A fixing portion 25 having a protruding fixing portion 25a and a protruding fixing portion 25b is provided at the bottom of the cylindrical main body, and the closing valve 20 is connected to the side bulging portion 53 via the protruding fixing portion 25a and the protruding fixing portion 25b. It is attached. At this time, the cylindrical connection portion extends adjacent to the side bulge portion 53. Although other connecting members can be connected to the cylindrical connecting portion, the side bulging portion 53 interferes with the connection when the cylindrical connecting portion and the other connecting member are connected. There is a possibility that it is difficult or impossible to connect the connecting member. Then, the structure which ensures a space between the cylindrical connection part and the side bulging part 53 is provided as the closing valve 20 of this embodiment. As the configuration, a first configuration (FIGS. 4 to 6) configured to move away from the fixed surface 53a of the side bulging portion 53 as the central axis C2 of the cylindrical connection portion of the shut-off valve 20 goes to the tip. Examples include a second configuration (FIGS. 7 to 9) configured to incline the central axis C <b> 1 of the cylindrical body with respect to the fixed surface 53 a of the side bulge portion 53.

以下に閉鎖弁２０の第１の構成及び第２の構成についてそれぞれ説明する。   Below, the 1st structure and 2nd structure of the closing valve 20 are each demonstrated.

（３−１）第１の構成の閉鎖弁２０
（ａ）第１の構成の外観構成
まず、第１の構成の閉鎖弁２０の外観構成について、図４〜図６を用いて以下に説明する。図４は第１の構成の閉鎖弁２０が側面膨出部５３に取り付けられた状態を示す斜視図である。図５は、図４の矢印方向からみた場合の第１の構成の閉鎖弁２０及び側面膨出部５３の正面図である。図６は図４のＩ切断面で切断した場合の第１の構成の閉鎖弁２０の断面図である。 (3-1) First configuration closing valve 20
(A) External configuration of first configuration First, an external configuration of the first configuration of the closing valve 20 will be described below with reference to FIGS. 4 to 6. FIG. 4 is a perspective view showing a state in which the closing valve 20 having the first configuration is attached to the side bulging portion 53. FIG. 5 is a front view of the shut-off valve 20 and the side bulging portion 53 of the first configuration when viewed from the direction of the arrow in FIG. 4. FIG. 6 is a cross-sectional view of the first configuration closing valve 20 cut along the I-cut plane of FIG. 4.

第１の構成の閉鎖弁２０は、第１円筒部２１、第２円筒部２２、第３円筒部２３、第４円筒部２４を有している。また、第１円筒部２１の先端には弁蓋７０が、第３円筒部２３の先端にはバルブコアキャップ８５が、第４円筒部２４の先端にはフレアナットなどのナット８８が取り付けられている。第４円筒部２４の先端に連絡配管１４等の他の接続部材が接続される場合には、ナット８８は取り外される。第１〜第４円筒部２１〜２４は、内部に貫通孔が設けられた概ね円筒形状をそれぞれ有しており、互いに貫通孔の内周面が連続するように一端が接続されている。第１円筒部２１及び第２円筒部２２はその中心軸Ｃ１が概ね同一軸状に位置しており、第１円筒部２１及び第２円筒部２２により円筒状本体を構成している。   The closing valve 20 having the first configuration includes a first cylindrical portion 21, a second cylindrical portion 22, a third cylindrical portion 23, and a fourth cylindrical portion 24. A valve lid 70 is attached to the tip of the first cylindrical portion 21, a valve core cap 85 is attached to the tip of the third cylindrical portion 23, and a nut 88 such as a flare nut is attached to the tip of the fourth cylindrical portion 24. . When another connecting member such as the communication pipe 14 is connected to the tip of the fourth cylindrical portion 24, the nut 88 is removed. Each of the first to fourth cylindrical portions 21 to 24 has a substantially cylindrical shape with a through hole provided therein, and one end thereof is connected so that the inner peripheral surfaces of the through holes are continuous with each other. The first cylindrical portion 21 and the second cylindrical portion 22 have their central axes C1 positioned substantially on the same axis, and the first cylindrical portion 21 and the second cylindrical portion 22 constitute a cylindrical main body.

第２円筒部２２の底部には、第２円筒部２２に連続する固定部２５が設けられている。固定部２５は、第２円筒部２２に対して突出する突出固定部２５ａ及び突出固定部２５ｂを有する。突出固定部２５ａと突出固定部２５ｂとは、第２円筒部２２の外側面に対して対称となる位置に設けられている。突出固定部２５ａには締結孔２５ａ−１が設けられており、突出固定部２５ｂにも同様に締結孔２５ｂ−１（図示せず）が設けられている。突出固定部２５ａ、２５ｂの締結孔２５ａ−１、２５ｂ−１と、閉鎖弁取付板５０の取付孔５２ａ−１、５２ａ−２（図３参照）とにネジが挿入され、ネジ止めされることにより閉鎖弁２０が閉鎖弁取付板５０に取り付けられる。よって、閉鎖弁２０の突出固定部２５ａ、２５ｂの固定面２５ｃと、側面膨出部５３の被固定面５３ａとが互いに面するように固定されている。そして、第１円筒部２１及び第２円筒部２２の中心軸Ｃ１は、突出固定部２５ａ、２５ｂの固定面２５ｃ及び側面膨出部５３の被固定面５３ａに対して概ね直交する。   A fixed portion 25 that is continuous with the second cylindrical portion 22 is provided at the bottom of the second cylindrical portion 22. The fixing portion 25 includes a protruding fixing portion 25 a and a protruding fixing portion 25 b that protrude with respect to the second cylindrical portion 22. The protrusion fixing part 25 a and the protrusion fixing part 25 b are provided at positions that are symmetrical with respect to the outer surface of the second cylindrical part 22. The protruding fixing part 25a is provided with a fastening hole 25a-1, and the protruding fixing part 25b is similarly provided with a fastening hole 25b-1 (not shown). Screws are inserted into the fastening holes 25a-1 and 25b-1 of the projecting fixing portions 25a and 25b and the mounting holes 52a-1 and 52a-2 (see FIG. 3) of the shut-off valve mounting plate 50 and screwed. Thus, the closing valve 20 is attached to the closing valve mounting plate 50. Therefore, the fixing surfaces 25c of the protruding fixing portions 25a and 25b of the closing valve 20 and the fixed surface 53a of the side bulge portion 53 are fixed so as to face each other. The central axes C1 of the first cylindrical portion 21 and the second cylindrical portion 22 are substantially orthogonal to the fixing surfaces 25c of the protruding fixing portions 25a and 25b and the fixed surface 53a of the side bulging portion 53.

第３円筒部２３の中心軸Ｃ３は、第１円筒部２１及び第２円筒部２２の中心軸Ｃ１と概ね直交する。一方、第４円筒部２４の中心軸Ｃ２は、第１円筒部２１及び第２円筒部２２の中心軸Ｃ１と斜めに交差する。より具体的には、第４円筒部２４の中心軸Ｃ２は、図５に示すようにその先端にいくほど側面膨出部５３の被固定面５３ａから離れる。この第４円筒部２４の他端には、図５、図６に示すように、連絡配管１４等を接続可能な第４接続ポート１１１が設けられている。第４円筒部２４は、先端に行くほど被固定面５３ａから離れるため、第４円筒部２４の先端と側面膨出部５３の被固定面５３ａとの間にスペースを確保することができる。よって、第４円筒部２４の第４接続ポート１１１と連絡配管１４等の他の接続部材との接続を、側面膨出部５３の被固定面５３ａとの接触を避けつつ容易に行うことができる。   The central axis C3 of the third cylindrical portion 23 is substantially orthogonal to the central axes C1 of the first cylindrical portion 21 and the second cylindrical portion 22. On the other hand, the central axis C <b> 2 of the fourth cylindrical portion 24 obliquely intersects with the central axes C <b> 1 of the first cylindrical portion 21 and the second cylindrical portion 22. More specifically, the central axis C2 of the fourth cylindrical portion 24 is further away from the fixed surface 53a of the side bulging portion 53 as it goes to the tip as shown in FIG. At the other end of the fourth cylindrical portion 24, as shown in FIGS. 5 and 6, a fourth connection port 111 to which the connection pipe 14 and the like can be connected is provided. Since the fourth cylindrical portion 24 moves away from the fixed surface 53a as it goes to the distal end, a space can be secured between the distal end of the fourth cylindrical portion 24 and the fixed surface 53a of the side bulged portion 53. Therefore, the connection between the fourth connection port 111 of the fourth cylindrical portion 24 and another connection member such as the connection pipe 14 can be easily performed while avoiding contact with the fixed surface 53a of the side bulge portion 53. .

（ｂ）第１の構成の断面構成
次に第１の構成の閉鎖弁２０の断面構成について主に図６を用いて説明する。 (B) Cross-sectional Configuration of First Configuration Next, a cross-sectional configuration of the first configuration closing valve 20 will be described mainly with reference to FIG.

第１の構成の閉鎖弁２０は、本体部８０、弁体８２、弁蓋７０、バルブコア８４、バルブコアキャップ８５及び図示しないナット８８を備える。本体部８０は、第１円筒部２１、第２円筒部２２、第３円筒部２３、第４円筒部２４を有する。各円筒部２１〜２４は、内部に貫通孔が設けられた略円筒形状をそれぞれ有しており、互いに貫通孔の内周面が連続するように一端が接続されている。第１円筒部２１の他端には、弁体８２を移動させるためのレンチが挿入される操作ポート１１５が設けられている。第２円筒部２２の他端には、室外機内の内部配管が接続される第２接続ポート１１２が設けられている。また、第２円筒部２２の他端には、閉鎖弁２０を側面膨出部５３に固定するための固定部２５が連続して形成されている。第３円筒部２３の他端には、真空ポンプ(図示せず)からのホースなどが接続されるサービスポート１１４が設けられている。第４円筒部２４の他端には、連絡配管１４等が接続される第４接続ポート１１１が設けられている。   The closing valve 20 having the first configuration includes a main body 80, a valve body 82, a valve lid 70, a valve core 84, a valve core cap 85, and a nut 88 (not shown). The main body 80 includes a first cylindrical part 21, a second cylindrical part 22, a third cylindrical part 23, and a fourth cylindrical part 24. Each of the cylindrical portions 21 to 24 has a substantially cylindrical shape with a through hole provided therein, and one end thereof is connected so that the inner peripheral surfaces of the through holes are continuous with each other. An operation port 115 into which a wrench for moving the valve body 82 is inserted is provided at the other end of the first cylindrical portion 21. A second connection port 112 to which an internal pipe in the outdoor unit is connected is provided at the other end of the second cylindrical portion 22. In addition, a fixing portion 25 for fixing the closing valve 20 to the side bulging portion 53 is continuously formed at the other end of the second cylindrical portion 22. At the other end of the third cylindrical portion 23, a service port 114 to which a hose from a vacuum pump (not shown) is connected is provided. The other end of the fourth cylindrical portion 24 is provided with a fourth connection port 111 to which the communication pipe 14 and the like are connected.

また、第４円筒部２４の直径Ｄ１は第３円筒部２３の直径Ｄ２よりも大きい（Ｄ１＞Ｄ２）。よって、第４円筒部２４に連絡配管１４等の他の接続部材を接続する際に側面膨出部５３の被固定面５３ａが邪魔になりやすい。しかし、上記の通り、第４円筒部２４は、先端に行くほど被固定面５３ａから離れるため、第４円筒部２４の先端と側面膨出部５３の被固定面５３ａとの間にスペースが確保され、被固定面５３ａが接続の邪魔になりにくい。一方、第３円筒部２３の直径は比較的小さいため第３円筒部２３に他の接続部材を接続する際に被固定面５３ａは邪魔になりにくい。   The diameter D1 of the fourth cylindrical portion 24 is larger than the diameter D2 of the third cylindrical portion 23 (D1> D2). Therefore, when the other connecting member such as the communication pipe 14 is connected to the fourth cylindrical portion 24, the fixed surface 53a of the side bulging portion 53 tends to be an obstacle. However, as described above, since the fourth cylindrical portion 24 moves away from the fixed surface 53a as it goes to the tip, a space is secured between the tip of the fourth cylindrical portion 24 and the fixed surface 53a of the side bulged portion 53. Thus, the fixed surface 53a is unlikely to obstruct the connection. On the other hand, since the diameter of the third cylindrical portion 23 is relatively small, the fixed surface 53a is less likely to get in the way when another connecting member is connected to the third cylindrical portion 23.

円筒状本体を構成する第１円筒部２１及び第２円筒部２２は、それらの中心軸Ｃ１が同一軸上にあり、直線状に並んで配置されている。第３円筒部２３は、第１円筒部２１及び第２円筒部２２に対して概ね９０°の角度を成している。   The first cylindrical portion 21 and the second cylindrical portion 22 constituting the cylindrical main body have their central axes C1 on the same axis and are arranged in a straight line. The third cylindrical portion 23 forms an angle of approximately 90 ° with respect to the first cylindrical portion 21 and the second cylindrical portion 22.

第４円筒部２４は、第１円筒部２１及び第２円筒部２２に対して、９０°よりも大きい角度を有して、図６中上方に延在するように配置されている。つまり、第４円筒部２４と第２円筒部２２との成す角度θが９０°よりも大きい。   The fourth cylindrical portion 24 has an angle larger than 90 ° with respect to the first cylindrical portion 21 and the second cylindrical portion 22, and is arranged to extend upward in FIG. That is, the angle θ formed by the fourth cylindrical portion 24 and the second cylindrical portion 22 is larger than 90 °.

第４円筒部２４の内部には、第１冷媒流路９５ａが設けられており、第２円筒部２２の内部には第２冷媒流路９５ｂが設けられている。また、第３円筒部２３の内部には、バルブコア通路９３が設けられており、第１円筒部２１の内部には、弁通路９４が設けられている。第１冷媒流路９５ａ、第２冷媒流路９５ｂ、バルブコア通路９３および弁通路９４は、中間流路９５ｃを中心にして４方に放射状に配置されており、中間流路９５ｃに連通している。第２冷媒流路９５ｂと弁通路９４とは中間流路９５ｃを挟んで同軸に配置されている。第１冷媒流路９５ａは、第２冷媒流路９５ｂに対して９０°よりも大きい角度を有して傾斜するように配置されている。バルブコア通路９３は、第２冷媒流路９５ｂに対して概ね９０°の角度を有して配置されている。   A first refrigerant channel 95 a is provided inside the fourth cylindrical part 24, and a second refrigerant channel 95 b is provided inside the second cylindrical part 22. A valve core passage 93 is provided inside the third cylindrical portion 23, and a valve passage 94 is provided inside the first cylindrical portion 21. The first refrigerant flow path 95a, the second refrigerant flow path 95b, the valve core passage 93, and the valve passage 94 are arranged radially in four directions around the intermediate flow path 95c, and communicate with the intermediate flow path 95c. . The second refrigerant channel 95b and the valve passage 94 are arranged coaxially with the intermediate channel 95c interposed therebetween. The first refrigerant channel 95a is arranged to be inclined with an angle larger than 90 ° with respect to the second refrigerant channel 95b. The valve core passage 93 is disposed with an angle of approximately 90 ° with respect to the second refrigerant passage 95b.

なお、バルブコア通路９３はバルブコア８４によって閉塞され、弁通路９４は弁体８２によって閉塞されるため、第１冷媒流路９５ａ、中間流路９５ｃおよび第２冷媒流路９５ｂは冷媒が流れる冷媒流路９５を形成している。以下、第２冷媒流路９５ｂと弁通路９４とを通る軸に平行な方向のうち弁通路９４から第２冷媒流路９５ｂへ向かう方向を第１方向（図６の矢印Ａ１参照）と呼び、第２冷媒流路９５ｂから弁通路９４へ向かう方向を第２方向（図６の矢印Ａ１と逆方向）と呼ぶこととする。中間流路９５ｃと第２冷媒流路９５ｂとの境界には、弁体８２の先端が当接・離反する弁座８１が設けられており、弁座８１は、第２方向へ向けて拡径するテーパ形状を有している。   Since the valve core passage 93 is closed by the valve core 84 and the valve passage 94 is closed by the valve body 82, the first refrigerant passage 95a, the intermediate passage 95c, and the second refrigerant passage 95b are refrigerant passages through which refrigerant flows. 95 is formed. Hereinafter, the direction from the valve passage 94 toward the second refrigerant passage 95b in the direction parallel to the axis passing through the second refrigerant passage 95b and the valve passage 94 is referred to as a first direction (see arrow A1 in FIG. 6). The direction from the second refrigerant channel 95b toward the valve passage 94 is referred to as a second direction (the direction opposite to the arrow A1 in FIG. 6). At the boundary between the intermediate flow path 95c and the second refrigerant flow path 95b, a valve seat 81 is provided in which the tip of the valve body 82 abuts and separates. The valve seat 81 increases in diameter in the second direction. It has a tapered shape.

弁体８２は、略円柱状の形状を有しており、第１円筒部２１の弁通路９４に軸方向に移動可能に配置されている。弁体８２の先端は、中間流路９５ｃに面しており、第１方向に向けて縮径するテーパ形状を有している。また、弁体８２の後端には６角レンチが挿入される６角穴（図示せず）が形成されており、６角レンチと共に弁体８２を回転させることによって弁体８２を軸方向に移動させることができる。   The valve body 82 has a substantially columnar shape, and is disposed in the valve passage 94 of the first cylindrical portion 21 so as to be movable in the axial direction. The tip of the valve body 82 faces the intermediate flow path 95c and has a tapered shape that decreases in diameter in the first direction. Further, a hexagonal hole (not shown) into which a hexagonal wrench is inserted is formed at the rear end of the valve body 82, and the valve body 82 is axially rotated by rotating the valve body 82 together with the hexagonal wrench. Can be moved.

図６に示すように冷媒流路９５が開かれた開状態においては、弁体８２の先端は、弁通路９４から中間流路９５ｃへと僅かに突出している。この状態においては、弁体８２の先端と第２冷媒流路９５ｂとの間は開かれており、中間流路９５ｃは開放されている。一方、冷媒流路９５が閉じられた閉状態においては、弁体８２の先端は弁座８１に当接している。この状態においては、弁体８２の先端と第２冷媒流路９５ｂとの間は隙間無く閉じられており、中間流路９５ｃは閉塞されている。閉鎖弁２０を閉じる場合には、弁体８２を第１方向に移動させることによって、弁体８２の先端と弁座８１とを当接させて、第１冷媒流路９５ａと第２冷媒流路９５ｂとの間を遮断する。また、閉鎖弁２０を開く場合には、弁体８２を第２方向に移動させることによって、その先端を弁座８１から離反させて、第１冷媒流路９５ａと第２冷媒流路９５ｂとを連通させる。なお、弁体８２の外周には環状の溝８２ａが形成されており、溝８２ａにはオーリング８３が外嵌されている。これにより、弁通路９４の内周面と弁体８２の外周面との間がシールされ、外部に冷媒が漏れないようにされている。   As shown in FIG. 6, in the open state in which the refrigerant flow path 95 is opened, the tip of the valve body 82 slightly protrudes from the valve passage 94 to the intermediate flow path 95c. In this state, the end of the valve body 82 and the second refrigerant flow path 95b are opened, and the intermediate flow path 95c is opened. On the other hand, in the closed state in which the refrigerant flow path 95 is closed, the tip of the valve body 82 is in contact with the valve seat 81. In this state, the tip of the valve body 82 and the second refrigerant flow path 95b are closed without a gap, and the intermediate flow path 95c is closed. When closing the shut-off valve 20, the valve body 82 is moved in the first direction to bring the tip of the valve body 82 into contact with the valve seat 81, so that the first refrigerant channel 95a and the second refrigerant channel Block between 95b. Further, when opening the closing valve 20, the valve body 82 is moved in the second direction, so that the tip of the valve body 82 is separated from the valve seat 81, and the first refrigerant channel 95a and the second refrigerant channel 95b are connected. Communicate. An annular groove 82a is formed on the outer periphery of the valve body 82, and an O-ring 83 is fitted on the groove 82a. Thereby, the space between the inner peripheral surface of the valve passage 94 and the outer peripheral surface of the valve element 82 is sealed, so that the refrigerant does not leak to the outside.

弁蓋７０は、通常時には第１円筒部２１の他端に取り付けられており、操作ポート１１５を塞ぐ。閉鎖弁２０の開閉が行われる場合には、第１円筒部２１の他端から取り外される。なお、弁蓋７０と本体部８０と間は、シール部材によりシールされている。   The valve lid 70 is normally attached to the other end of the first cylindrical portion 21 and closes the operation port 115. When the closing valve 20 is opened and closed, it is removed from the other end of the first cylindrical portion 21. The valve lid 70 and the main body 80 are sealed with a seal member.

バルブコア８４はバルブコア通路９３に挿入されており、バルブコア通路９３を塞ぐ。バルブコア８４に真空ポンプからのホースが接続されると、バルブコア８４が開き、サービスポート１１４および第４接続ポート１１１を介して第４接続ポート１１１に接続された連絡配管１４内の真空引きが行われる。   The valve core 84 is inserted into the valve core passage 93 and closes the valve core passage 93. When the hose from the vacuum pump is connected to the valve core 84, the valve core 84 is opened, and the communication pipe 14 connected to the fourth connection port 111 through the service port 114 and the fourth connection port 111 is evacuated. .

バルブコアキャップ８５は、通常時は第３円筒部２３の他端に取り付けられており、サービスポート１１４を塞ぐ。バルブコアキャップ８５は、連絡配管１４内の真空引きを行う場合には第３円筒部２３の他端から取り外される。なお、バルブコアキャップ８５の内周のネジ１１８と第３円筒部２３の内周のネジ１１７との間はシールされている。   The valve core cap 85 is normally attached to the other end of the third cylindrical portion 23 and closes the service port 114. The valve core cap 85 is removed from the other end of the third cylindrical portion 23 when evacuating the communication pipe 14. The space between the inner peripheral screw 118 of the valve core cap 85 and the inner peripheral screw 117 of the third cylindrical portion 23 is sealed.

図示しないナットは、第４接続ポート１１１の外周に形成されたネジ１１６と螺合するネジを内周に有し、第４接続ポート１１１と連絡配管１４とを接続する。   A nut (not shown) has a screw threadedly engaged with a screw 116 formed on the outer periphery of the fourth connection port 111 on the inner periphery, and connects the fourth connection port 111 and the communication pipe 14.

（３−２）第２の構成の閉鎖弁２０
（ａ）第２の構成の外観構成
次に、第２の構成の閉鎖弁２０の外観構成について、図７〜図９を用いて以下に説明する。図７は第２の構成の閉鎖弁２０が側面膨出部５３に取り付けられた状態を示す斜視図である。図８は、図７の矢印方向からみた場合の第２の構成の閉鎖弁２０及び側面膨出部５３の正面図である。図９は図７のＩ切断面で切断した場合の第２の構成の閉鎖弁２０の断面図である。 (3-2) Shutdown valve 20 of the second configuration
(A) External Configuration of Second Configuration Next, an external configuration of the second configuration closing valve 20 will be described below with reference to FIGS. 7 to 9. FIG. 7 is a perspective view showing a state in which the closing valve 20 having the second configuration is attached to the side bulging portion 53. FIG. 8 is a front view of the closing valve 20 and the side bulging portion 53 of the second configuration when viewed from the direction of the arrow in FIG. FIG. 9 is a cross-sectional view of the closing valve 20 having the second configuration when cut along the I-cut surface of FIG. 7.

第２の構成の閉鎖弁２０では、第１〜第４円筒部２１〜２４が内部に貫通孔が設けられた概ね円筒形状をそれぞれ有しており、互いに貫通孔の内周面が連続するように一端が接続されている。第１円筒部２１及び第２円筒部２２はその中心軸Ｃ１が概ね同一軸状に位置しており、第１円筒部２１及び第２円筒部２２により円筒状本体を構成している。第３円筒部２３及び第４円筒部２４はその中心軸Ｃ２が概ね同一軸状に位置しており、中心軸Ｃ１と中心軸Ｃ２とは概ね直交する。なお、第１円筒部２１の先端には弁蓋７０が、第３円筒部２３の先端にはバルブコアキャップ８５が、第４円筒部２４の先端にはフレアナットなどのナット８８が取り付けられている。第４円筒部２４の先端に連絡配管１４等の他の接続部材が接続される場合には、ナット８８は取り外される。   In the shut-off valve 20 having the second configuration, the first to fourth cylindrical portions 21 to 24 each have a substantially cylindrical shape in which a through hole is provided, and the inner peripheral surfaces of the through holes are continuous with each other. One end is connected to. The first cylindrical portion 21 and the second cylindrical portion 22 have their central axes C1 positioned substantially on the same axis, and the first cylindrical portion 21 and the second cylindrical portion 22 constitute a cylindrical main body. The third cylindrical portion 23 and the fourth cylindrical portion 24 have their central axes C2 located substantially on the same axis, and the central axis C1 and the central axis C2 are substantially orthogonal. A valve lid 70 is attached to the tip of the first cylindrical portion 21, a valve core cap 85 is attached to the tip of the third cylindrical portion 23, and a nut 88 such as a flare nut is attached to the tip of the fourth cylindrical portion 24. . When another connecting member such as the communication pipe 14 is connected to the tip of the fourth cylindrical portion 24, the nut 88 is removed.

第２円筒部２２の底部には、第２円筒部２２に連続する固定部２５が設けられている。固定部２５は、第２円筒部２２の外側面に対して対称に突出する突出固定部２５ａ及び突出固定部２５ｂを有する。この突出固定部２５ａ、２５ｂの締結孔２５ａ−１、２５ｂ−１と、閉鎖弁取付板５０の取付孔５２ａ−１、５２ａ−２（図３参照）とにネジが挿入され、ネジ止めされることにより閉鎖弁２０が閉鎖弁取付板５０に取り付けられる。   A fixed portion 25 that is continuous with the second cylindrical portion 22 is provided at the bottom of the second cylindrical portion 22. The fixing portion 25 includes a protruding fixing portion 25 a and a protruding fixing portion 25 b that protrude symmetrically with respect to the outer surface of the second cylindrical portion 22. Screws are inserted into the fastening holes 25a-1 and 25b-1 of the projecting fixing portions 25a and 25b and the mounting holes 52a-1 and 52a-2 (see FIG. 3) of the shut-off valve mounting plate 50 and screwed. Thus, the closing valve 20 is attached to the closing valve mounting plate 50.

第２の構成の閉鎖弁２０では、突出固定部２５ａ、２５ｂが第２円筒部２２に対して斜めに取り付けられている。なお、突出固定部２５ａ、２５ｂの厚みは一定である。突出固定部２５ａ、２５ｂを側面膨出部５３の被固定面５３ａに取り付けると、第１円筒部２１及び第２円筒部２２からなる円筒状本体は、側面膨出部５３の被固定面５３ａに対して中心軸Ｃ１が傾斜する。より具体的には、第１円筒部２１及び第２円筒部２２の中心軸Ｃ１は、被固定面５３ａに直交する仮想の中心軸Ｃ５３ａに対して傾斜する。ここで、突出固定部２５ａ、２５ｂの固定面２５ｃと側面膨出部５３の被固定面５３ａとは同一面にある。よって、突出固定部２５ａ、２５ｂの固定面２５ｃと交差する中心軸Ｃ５３ａが、第１円筒部２１及び第２円筒部２２の中心軸Ｃ１に対して傾斜するように突出固定部２５ａ、２５ｂが第２円筒部２２の外側面に取り付けられていると言える。   In the closing valve 20 having the second configuration, the protruding fixing portions 25 a and 25 b are attached to the second cylindrical portion 22 at an angle. In addition, the thickness of the protrusion fixing | fixed part 25a, 25b is constant. When the protruding fixing portions 25 a and 25 b are attached to the fixed surface 53 a of the side bulging portion 53, the cylindrical main body composed of the first cylindrical portion 21 and the second cylindrical portion 22 is fixed to the fixed surface 53 a of the side bulging portion 53. On the other hand, the central axis C1 is inclined. More specifically, the central axes C1 of the first cylindrical portion 21 and the second cylindrical portion 22 are inclined with respect to a virtual central axis C53a orthogonal to the fixed surface 53a. Here, the fixing surfaces 25c of the protruding fixing portions 25a and 25b and the fixed surface 53a of the side bulging portion 53 are on the same plane. Therefore, the protrusion fixing portions 25a and 25b are arranged so that the central axis C53a intersecting the fixing surface 25c of the protrusion fixing portions 25a and 25b is inclined with respect to the center axis C1 of the first cylindrical portion 21 and the second cylindrical portion 22. 2 It can be said that it is attached to the outer surface of the cylindrical portion 22.

ここで、第４円筒部２４は、第１円筒部２１及び第２円筒部２２に対して概ね９０°の角度を有して延在している。そのため、第４円筒部２４の先端は側面膨出部５３の被固定面５３ａから離れるように中心軸Ｃ２が被固定面５３ａに対して傾斜する。よって、第４円筒部２４の先端と側面膨出部５３の被固定面５３ａとの間にスペースを確保することができ、第４円筒部２４の第４接続ポート１１１と連絡配管１４等の他の接続部材との接続を、側面膨出部５３の被固定面５３ａとの接触を避けつつ容易に行うことができる。   Here, the fourth cylindrical portion 24 extends at an angle of approximately 90 ° with respect to the first cylindrical portion 21 and the second cylindrical portion 22. Therefore, the center axis C2 is inclined with respect to the fixed surface 53a so that the tip of the fourth cylindrical portion 24 is separated from the fixed surface 53a of the side bulge portion 53. Therefore, a space can be secured between the tip of the fourth cylindrical portion 24 and the fixed surface 53a of the side bulged portion 53, and the fourth connection port 111 of the fourth cylindrical portion 24, the connection pipe 14, and the like. This connection member can be easily made while avoiding contact with the fixed surface 53a of the side bulging portion 53.

（ｂ）第２の構成の断面構成
次に第２の構成の断面構成について、主に図９を用いて説明する。なお、第１の構成の閉鎖弁２０と重複する構成については説明を省略するか簡単に説明する。 (B) Sectional Configuration of Second Configuration Next, a sectional configuration of the second configuration will be described mainly with reference to FIG. In addition, about the structure which overlaps with the closing valve 20 of a 1st structure, description is abbreviate | omitted or demonstrated easily.

第２の構成の閉鎖弁２０は、本体部８０、弁体８２、弁蓋７０、バルブコア８４、バルブコアキャップ８５及び図示しないナット８８を備える。第１円筒部２１の他端には操作ポート１１５が、第２円筒部２２の他端には第２接続ポート１１２が、第３円筒部２３の他端にはサービスポート１１４が、第４円筒部２４の他端には、連絡配管１４等が接続される第４接続ポート１１１が設けられている。   The closing valve 20 of the second configuration includes a main body 80, a valve body 82, a valve lid 70, a valve core 84, a valve core cap 85, and a nut 88 (not shown). An operation port 115 is provided at the other end of the first cylindrical portion 21, a second connection port 112 is provided at the other end of the second cylindrical portion 22, a service port 114 is provided at the other end of the third cylindrical portion 23, and a fourth cylinder. At the other end of the section 24, a fourth connection port 111 to which the communication pipe 14 and the like are connected is provided.

また、第２円筒部２２の他端には、閉鎖弁２０を側面膨出部５３に固定するための固定部２５が連続して形成されている。固定部２５は突出固定部２５ａ、２５ｂを有しており、突出固定部２５ａ、２５ｂは、図９に示すように第２円筒部２２の外側面に対して斜めに取り付けられている。よって、突出固定部２５ａ、２５ｂを側面膨出部５３の被固定面５３ａに取り付けると、第４円筒部２４の先端は側面膨出部５３の被固定面５３ａから離れるように中心軸Ｃ２が被固定面５３ａに対して傾斜し、第４円筒部２４とケース側壁部４１２の鉛直面との間にスペースを確保できる。これにより、第４円筒部２４に連絡配管１４を接続する際の作業性を向上させることができる。   In addition, a fixing portion 25 for fixing the closing valve 20 to the side bulging portion 53 is continuously formed at the other end of the second cylindrical portion 22. The fixing portion 25 has protruding fixing portions 25a and 25b, and the protruding fixing portions 25a and 25b are attached obliquely to the outer surface of the second cylindrical portion 22 as shown in FIG. Therefore, when the protruding fixing portions 25a and 25b are attached to the fixed surface 53a of the side bulging portion 53, the central axis C2 is set so that the tip of the fourth cylindrical portion 24 is separated from the fixing surface 53a of the side bulging portion 53. It is inclined with respect to the fixed surface 53a, and a space can be secured between the fourth cylindrical portion 24 and the vertical surface of the case side wall portion 412. Thereby, workability | operativity at the time of connecting the communication piping 14 to the 4th cylindrical part 24 can be improved.

また、第４円筒部２４の直径Ｄ１は第３円筒部２３の直径Ｄ２よりも大きい（Ｄ１＞Ｄ２）。よって、第４円筒部２４に連絡配管１４等の他の接続部材を接続する際に側面膨出部５３の被固定面５３ａは邪魔になりやすい。しかし、上記の通り、第４円筒部２４の先端は側面膨出部５３の被固定面５３ａから離れるように中心軸Ｃ２が被固定面５３ａに対して傾斜する。よって、第４円筒部２４の先端と側面膨出部５３の被固定面５３ａとの間にスペースが確保され、被固定面５３ａが接続の邪魔になりにくい。一方、第３円筒部２３の直径は比較的小さいため第３円筒部２３に別の接続部材を接続する際に被固定面５３ａは邪魔になりにくい。特に、第２の構成の閉鎖弁２０では、第４円筒部２４及び第３円筒部２３の中心軸Ｃ２が同一軸状にあり、かつ、第４円筒部２４の先端が側面膨出部５３の被固定面５３ａから離れるように被固定面５３ａに対して傾斜している。よって、第３円筒部２３の先端は被固定面５３ａに対して近づくように傾斜している。しかし、第３円筒部２３の直径は比較的小さいため、第３円筒部２３と被固定面５３ａとの間に或る程度のスペースを確保でき、第３円筒部２３に別の接続部材を接続する際に被固定面５３ａは邪魔になりにくい。   The diameter D1 of the fourth cylindrical portion 24 is larger than the diameter D2 of the third cylindrical portion 23 (D1> D2). Therefore, when other connection members such as the communication pipe 14 are connected to the fourth cylindrical portion 24, the fixed surface 53a of the side surface bulging portion 53 tends to become an obstacle. However, as described above, the central axis C2 is inclined with respect to the fixed surface 53a so that the tip of the fourth cylindrical portion 24 is separated from the fixed surface 53a of the side bulge portion 53. Therefore, a space is secured between the tip of the fourth cylindrical portion 24 and the fixed surface 53a of the side bulging portion 53, and the fixed surface 53a is unlikely to obstruct connection. On the other hand, since the diameter of the third cylindrical portion 23 is relatively small, the fixed surface 53a is less likely to get in the way when another connecting member is connected to the third cylindrical portion 23. In particular, in the shut-off valve 20 of the second configuration, the central axes C2 of the fourth cylindrical portion 24 and the third cylindrical portion 23 are the same axis, and the tip of the fourth cylindrical portion 24 is the side bulged portion 53. It inclines with respect to the to-be-fixed surface 53a so that it may leave | separate from the to-be-fixed surface 53a. Therefore, the tip of the third cylindrical portion 23 is inclined so as to approach the fixed surface 53a. However, since the diameter of the third cylindrical portion 23 is relatively small, a certain amount of space can be secured between the third cylindrical portion 23 and the fixed surface 53a, and another connection member is connected to the third cylindrical portion 23. In doing so, the fixed surface 53a is less likely to get in the way.

円筒状本体を構成する第１円筒部２１及び第２円筒部２２は、それらの中心軸Ｃ１が同一軸上にあり、直線状に並んで配置されている。第３円筒部２３及び第４円筒部２４は、第１円筒部２１及び第２円筒部２２に対して概ね９０°の角度を成している。   The first cylindrical portion 21 and the second cylindrical portion 22 constituting the cylindrical main body have their central axes C1 on the same axis and are arranged in a straight line. The third cylindrical portion 23 and the fourth cylindrical portion 24 form an angle of approximately 90 ° with respect to the first cylindrical portion 21 and the second cylindrical portion 22.

第１冷媒流路９５ａ、第２冷媒流路９５ｂ、バルブコア通路９３および弁通路９４は、中間流路９５ｃを中心にして４方に放射状に配置されており、中間流路９５ｃに連通している。また、第１冷媒流路９５ａとバルブコア通路９３とは中間流路９５ｃを挟んで同軸に配置され、第２冷媒流路９５ｂと弁通路９４とは中間流路９５ｃを挟んで同軸に配置されている。このため、冷媒流路９５は、途中で９０度に屈曲したＬ字型の形状となっている。   The first refrigerant flow path 95a, the second refrigerant flow path 95b, the valve core passage 93, and the valve passage 94 are arranged radially in four directions around the intermediate flow path 95c, and communicate with the intermediate flow path 95c. . The first refrigerant flow path 95a and the valve core passage 93 are arranged coaxially with the intermediate flow path 95c interposed therebetween, and the second refrigerant flow path 95b and the valve passage 94 are arranged coaxially with the intermediate flow path 95c interposed therebetween. Yes. For this reason, the refrigerant flow path 95 has an L-shape bent at 90 degrees in the middle.

その他の構成については、第１の構成の閉鎖弁２０と同様であるので説明を省略する。   The other configuration is the same as that of the first configuration of the shut-off valve 20, and the description thereof is omitted.

Thereby, a space can be secured between the tip of the fourth cylindrical portion 24 and the fixed surface 53a. Therefore, the connection between the fourth cylindrical portion 24 and the other connecting member can be easily performed while avoiding contact with the fixed surface 53a of the side bulging portion 53.

（４−２）
閉鎖弁２０は、第１円筒部２１及び第２円筒部２２（円筒状本体）をさらに備える。第１円筒部２１及び第２円筒部２２（円筒状本体）は、側面膨出部５３の被固定面５３ａに対して９０°の角度を持って固定部２５から延在する。第４円筒部２４は第１円筒部２１及び第２円筒部２２（円筒状本体）と接続されており、被固定面５３ａと隣接する側において、第１円筒部２１及び第２円筒部２２（円筒状本体）と第４円筒部２４とのなす角度が鈍角である。 (4-2)
The shut-off valve 20 further includes a first cylindrical portion 21 and a second cylindrical portion 22 (cylindrical main body). The first cylindrical portion 21 and the second cylindrical portion 22 (cylindrical main body) extend from the fixed portion 25 with an angle of 90 ° with respect to the fixed surface 53a of the side bulged portion 53. The fourth cylindrical portion 24 is connected to the first cylindrical portion 21 and the second cylindrical portion 22 (cylindrical main body), and on the side adjacent to the fixed surface 53a, the first cylindrical portion 21 and the second cylindrical portion 22 ( The angle formed by the cylindrical main body) and the fourth cylindrical portion 24 is an obtuse angle.

上記の通り、第１円筒部２１及び第２円筒部２２（円筒状本体）は、側面膨出部５３の被固定面５３ａに対して９０°の角度を持って固定部２５から鉛直上方に延在している。第４円筒部２４は、第１円筒部２１及び第２円筒部２２（円筒状本体）に対して鈍角をなして第１円筒部２１及び第２円筒部２２（円筒状本体）から斜め上方に分岐している。これにより、第４円筒部２４の先端と被固定面５３ａとの間にスペースを確保することができ、第４円筒部２４と他の接続部材との接続を、側面膨出部５３の被固定面５３ａとの接触を避けつつ容易に行うことができる。   As described above, the first cylindrical portion 21 and the second cylindrical portion 22 (cylindrical main body) extend vertically upward from the fixed portion 25 with an angle of 90 ° with respect to the fixed surface 53a of the side bulged portion 53. Exist. The fourth cylindrical portion 24 forms an obtuse angle with respect to the first cylindrical portion 21 and the second cylindrical portion 22 (cylindrical main body) and obliquely upward from the first cylindrical portion 21 and the second cylindrical portion 22 (cylindrical main body). Branched. Thereby, a space can be secured between the tip of the fourth cylindrical portion 24 and the fixed surface 53a, and the connection between the fourth cylindrical portion 24 and the other connecting member is fixed to the side bulged portion 53. This can be easily performed while avoiding contact with the surface 53a.

（４−３）
閉鎖弁２０は、第１円筒部２１及び第２円筒部２２（円筒状本体）をさらに備える。第１円筒部２１及び第２円筒部２２（円筒状本体）は、側面膨出部５３の被固定面５３ａに対して９０°の角度を持つ仮想軸に対して中心軸Ｃ１が傾斜するように固定部２５から延在する。第４円筒部２４は第１円筒部２１及び第２円筒部２２（円筒状本体）に対して９０°の角度を有して延在している。 (4-3)
The shut-off valve 20 further includes a first cylindrical portion 21 and a second cylindrical portion 22 (cylindrical main body). The first cylindrical portion 21 and the second cylindrical portion 22 (cylindrical main body) are arranged such that the central axis C1 is inclined with respect to a virtual axis having an angle of 90 ° with respect to the fixed surface 53a of the side bulged portion 53. It extends from the fixed part 25. The fourth cylindrical portion 24 extends at an angle of 90 ° with respect to the first cylindrical portion 21 and the second cylindrical portion 22 (cylindrical main body).

第４円筒部２４と第１円筒部２１及び第２円筒部２２（円筒状本体）とは９０°の角度を有するが、固定部２５から延在する第１円筒部２１及び第２円筒部２２（円筒状本体）が被固定面５３ａに対して傾斜している。これにより、第４円筒部２４の先端は側面膨出部５３の被固定面５３ａから離れるように中心軸Ｃ２が傾斜する。よって、第４円筒部２４の先端と被固定面５３ａとの間にスペースを確保することができ、第４円筒部２４と他の接続部材との接続を、側面膨出部５３の被固定面５３ａとの接触を避けつつ容易に行うことができる。   The fourth cylindrical portion 24, the first cylindrical portion 21, and the second cylindrical portion 22 (cylindrical main body) have an angle of 90 °, but the first cylindrical portion 21 and the second cylindrical portion 22 extending from the fixed portion 25. The (cylindrical main body) is inclined with respect to the fixed surface 53a. As a result, the central axis C2 is inclined so that the tip of the fourth cylindrical portion 24 is separated from the fixed surface 53a of the side bulge portion 53. Therefore, a space can be secured between the tip of the fourth cylindrical portion 24 and the fixed surface 53a, and the connection between the fourth cylindrical portion 24 and the other connecting member is connected to the fixed surface of the side bulging portion 53. This can be done easily while avoiding contact with 53a.

（４−４）
閉鎖弁２０は、第１円筒部２１及び第２円筒部２２（円筒状本体）に対して第４円筒部２４と対向するように延在する第３円筒部２３をさらに備える。 (4-4)
The shut-off valve 20 further includes a third cylindrical portion 23 that extends so as to face the fourth cylindrical portion 24 with respect to the first cylindrical portion 21 and the second cylindrical portion 22 (cylindrical main body).

第１円筒部２１及び第２円筒部２２（円筒状本体）に対して第４円筒部２４と対向する位置に第３円筒部２３を設けることで、さらに別の接続部材を第３円筒部２３に接続可能である。   By providing the third cylindrical portion 23 at a position opposed to the fourth cylindrical portion 24 with respect to the first cylindrical portion 21 and the second cylindrical portion 22 (cylindrical main body), another connecting member is provided as the third cylindrical portion 23. Can be connected to.

（４−５）
閉鎖弁２０は、第３円筒部２３は第４円筒部２４よりも直径が小さい。そのため、第３円筒部２３と別の接続部材とを接続する際に側面膨出部５３の被固定面５３ａが接続の邪魔になりにくい。 (4-5)
In the closing valve 20, the third cylindrical portion 23 has a smaller diameter than the fourth cylindrical portion 24. Therefore, when the third cylindrical portion 23 and another connecting member are connected, the fixed surface 53a of the side bulging portion 53 is unlikely to obstruct the connection.

（４−６）
閉鎖弁２０は、第３円筒部２３は第１円筒部２１及び第２円筒部２２（円筒状本体）に対して９０°の角度を有して延在している。 (4-6)
In the closing valve 20, the third cylindrical portion 23 extends at an angle of 90 ° with respect to the first cylindrical portion 21 and the second cylindrical portion 22 (cylindrical main body).

上述の通り、第３円筒部２３の直径は第４円筒部２４の直径よりも小さいため、第３円筒部２３が第１円筒部２１及び第２円筒部２２（円筒状本体）に対して９０°の角度を有して延在していても、第３円筒部２３と側面膨出部５３の被固定面５３ａとの間に或る程度のスペースを確保できる。よって、第３円筒部２３と別の接続部材とを接続する際に側面膨出部５３の被固定面５３ａが接続の邪魔になりにくい。   As described above, since the diameter of the third cylindrical portion 23 is smaller than the diameter of the fourth cylindrical portion 24, the third cylindrical portion 23 is 90 relative to the first cylindrical portion 21 and the second cylindrical portion 22 (cylindrical main body). Even if it extends at an angle of °, a certain amount of space can be secured between the third cylindrical portion 23 and the fixed surface 53 a of the side bulging portion 53. Therefore, when the third cylindrical portion 23 and another connecting member are connected, the fixed surface 53a of the side bulging portion 53 is unlikely to obstruct the connection.

（５−１）変形例１Ａ
上記実施形態では３つの冷媒流路を有するガス冷媒用閉鎖弁２０ａを例に説明したが、本発明は２つの冷媒流路を有する液冷媒用閉鎖弁２０ｂについても適用可能である。液冷媒用閉鎖弁２０ｂは、ガス冷媒用閉鎖弁２０ａとは異なり、サービスポート１１４が設けられる第３円筒部２３を有していない。 (5) Modification (5-1) Modification 1A
In the above embodiment, the gas refrigerant closing valve 20a having three refrigerant flow paths has been described as an example, but the present invention is also applicable to a liquid refrigerant closing valve 20b having two refrigerant flow paths. Unlike the gas refrigerant closing valve 20a, the liquid refrigerant closing valve 20b does not have the third cylindrical portion 23 in which the service port 114 is provided.

液冷媒用閉鎖弁２０ｂに第１の構成を適用した場合には、連絡配管１４等が接続される第４接続ポート１１１側の第４円筒部２４は、先端にいくほど側面膨出部５３の被固定面５３ａから離れるように中心軸Ｃ２が被固定面５３ａに対して傾斜している。   When the first configuration is applied to the liquid refrigerant shutoff valve 20b, the fourth cylindrical portion 24 on the fourth connection port 111 side to which the communication pipe 14 and the like are connected has the side bulging portion 53 closer to the tip. The central axis C2 is inclined with respect to the fixed surface 53a so as to be away from the fixed surface 53a.

The central axis C1 is inclined. At this time, the protruding fixing portions 25 a and 25 b are attached obliquely to the second cylindrical portion 22 , and therefore the tip of the fourth cylindrical portion 24 is centered so as to be separated from the fixed surface 53 a of the side bulging portion 53. The axis C2 is inclined with respect to the fixed surface 53a.

以上より、液冷媒用閉鎖弁２０ｂにおいても本実施形態のガス冷媒用閉鎖弁２０ａと同様の効果を得ることができる。   As described above, the same effect as that of the gas refrigerant closing valve 20a of the present embodiment can be obtained in the liquid refrigerant closing valve 20b.

（５−２）変形例１Ｂ
上記実施形態では、閉鎖弁取付板５０がケーシング４１に取り付けられた状態において、側面部５１及び側面膨出部５３は縦長に形成されている。しかし、閉鎖弁取付板５０の形状は限定されず、例えば側面部５１及び側面膨出部５３はガス冷媒用閉鎖弁２０ａ、液冷媒用閉鎖弁２０ｂの位置に応じて横長に形成されていてもよい。 (5-2) Modification 1B
In the above embodiment, in the state where the closing valve mounting plate 50 is mounted on the casing 41, the side surface portion 51 and the side surface bulging portion 53 are formed in a vertically long shape. However, the shape of the closing valve mounting plate 50 is not limited. For example, the side surface portion 51 and the side surface bulging portion 53 may be formed horizontally long depending on the positions of the gas refrigerant closing valve 20a and the liquid refrigerant closing valve 20b. Good.

（５−３）変形例１Ｃ
上記実施形態では第４円筒部２４に連絡配管１４が接続される際に、第４円筒部２４の先端と側面膨出部５３の被固定面５３ａとの間にスペースを確保する構成を開示した。しかし、第４円筒部２４には連絡配管１４以外の接続部材が接続されてもよい。この場合にも、第４円筒部２４の先端と側面膨出部５３の被固定面５３ａとの間にスペースを確保することで、第４円筒部２４に他の接続部材を接続する際に被固定面５３ａが邪魔になりにくい。 (5-3) Modification 1C
In the said embodiment, when the connection piping 14 was connected to the 4th cylindrical part 24, the structure which ensures a space between the front-end | tip of the 4th cylindrical part 24 and the to-be-fixed surface 53a of the side bulging part 53 was disclosed. . However, a connection member other than the communication pipe 14 may be connected to the fourth cylindrical portion 24. Also in this case, a space is secured between the tip of the fourth cylindrical portion 24 and the fixed surface 53a of the side bulged portion 53, so that when the other connecting member is connected to the fourth cylindrical portion 24, The fixed surface 53a is unlikely to get in the way.

上記実施形態では室外機と室内機とを接続する連絡配管１４が接続される閉鎖弁を例に挙げて説明している。しかし、本発明は、接続部材が接続可能な接続ポートを有する各種弁にも適用可能である。 (5-4) Modification 1D
In the above-described embodiment, the closing valve to which the communication pipe 14 that connects the outdoor unit and the indoor unit is connected is described as an example. However, the present invention can also be applied to various valves having connection ports to which connection members can be connected.

本発明は、弁に接続部材を容易に接続することが可能との効果を有し、閉鎖弁等の各種弁に適用可能である。   The present invention has an effect that a connecting member can be easily connected to a valve, and can be applied to various valves such as a closing valve.
