Description

本発明は止水機能を有する給水管に関する。   The present invention relates to a water supply pipe having a water stop function.

従来の給水管は単なる管であり、止水機能を有するものでなかった。
なし Conventional water supply pipes are merely pipes and do not have a water stop function.
None

従来の給水管は単なる管であったため、施工現場で給水管に止水機能を付与する際には、給水管に止水弁を接続する必要があった。そのため、施工現場で給水管に止水弁を接続する作業が面倒であるという欠点があった。   Since the conventional water supply pipe was a mere pipe, it was necessary to connect a water stop valve to the water supply pipe when providing a water stop function to the water supply pipe at the construction site. For this reason, there is a drawback that the work of connecting the water stop valve to the water supply pipe at the construction site is troublesome.

本発明は前記欠点を解消するために以下の如き手段を採用した。
（１）請求項１の発明は、側周部に内外を連通させる開口を有する管本体と、この管本体の、開口が形成された部分の内部に収納された、弁座を有する弁ケーシングと、この弁ケーシング内に収納された可動の弁体と、前記開口に嵌められた弁体作動部材とを有するものである。
（２）請求項２の発明は、前記弁ケーシングが、管本体の軸心方向に所定間隔をあけてなる一対の弁ケーシング半体からなり、これら弁ケーシング半体の相互に対向する部分各々に、管本体の軸心を中心とする環状の弁座が設けられ、これら弁座にボール弁体が当接させられ、このボール弁体が管本体の軸心と直交する軸心を中心として閉位置と開位置との間で回転自在となされ、前記ボール弁体には、開位置において両弁座を連通させる貫通孔が形成されている請求項１記載のものである。 The present invention employs the following means in order to eliminate the above disadvantages.
(1) The invention according to claim 1 is a pipe main body having an opening for communicating the inside and the outside with a side peripheral portion, and a valve casing having a valve seat housed in a portion of the pipe main body where the opening is formed. The movable valve body housed in the valve casing and the valve body actuating member fitted in the opening are provided.
(2) In the invention of claim 2, the valve casing comprises a pair of valve casing halves with a predetermined interval in the axial direction of the pipe body, and each of the valve casing halves facing each other. An annular valve seat centered on the axis of the pipe body is provided, and a ball valve body is brought into contact with the valve seat, and the ball valve body is closed about an axis perpendicular to the axis of the pipe body. The ball valve body is rotatable between a position and an open position, and the ball valve body is formed with a through hole for communicating both valve seats in the open position.

本発明は前記した如き構成によって以下の如き効果を奏する。
（１）請求項１の発明によれば、給水管に止水機能が付与されているので、施工現場で給水管に止水弁を接続する面倒な作業が不要である。
（２）請求項２の発明によれば、弁ケーシングが一対の弁ケーシング半体からなるものであるから、管本体内への弁ケーシング半体及びボール弁体の収納作業が行いやすい。 The present invention has the following effects by the configuration as described above.
(1) According to the invention of claim 1, since the water stop function is given to the water supply pipe, the troublesome work of connecting the water stop valve to the water supply pipe at the construction site is unnecessary.
(2) According to the invention of claim 2, since the valve casing is composed of a pair of valve casing halves, it is easy to store the valve casing half and the ball valve body in the pipe body.

以下に本発明の実施の形態を説明する。
なお、この説明において、左とは図１左側を、右とは同図右側をいい、上とは図１上側を、下とは同図下側をいう。 Embodiments of the present invention will be described below.
In this description, the left means the left side of FIG. 1, the right means the right side of the figure, the upper means the upper side of FIG. 1, and the lower means the lower side of the figure.

止水機能を有する給水管１は、任意長さの（例えば５０ｃｍ程度の長さの）、軸心を上下方向に向けた管本体３を有している。前記管本体３には膨出部５が左側に膨出するかたちで形成されている。前記膨出部５は、軸心を水平とした円筒部５ａと、この円筒部５ａの左端に連設された平坦部５ｂとを有している。前記平坦部５ｂに、管本体３の内外を連通させる中心線を水平とした円形の開口６が形成されている。   The water supply pipe 1 having a water stop function has a pipe body 3 having an arbitrary length (for example, a length of about 50 cm) and an axial center directed in the vertical direction. The tube body 3 is formed with a bulging portion 5 bulging to the left. The bulging portion 5 includes a cylindrical portion 5a having a horizontal axis, and a flat portion 5b continuously provided at the left end of the cylindrical portion 5a. A circular opening 6 is formed in the flat portion 5b with a horizontal center line that communicates the inside and the outside of the tube body 3.

前記管本体３の、開口６が形成された部分の内部に弁ケーシング８が収納・固定されている。前記弁ケーシング８は、管本体３の軸心方向に所定間隔をあけてなる上下一対の弁ケーシング半体９から構成されている。前記弁ケーシング半体９の相互に対向する部分各々に、管本体３の軸心を中心とする、合成樹脂等からなる環状の弁座１０が設けられ、これら弁座１０にボール弁体１２が当接させられ、このボール弁体１２が管本体３の軸心と直交する軸心を中心として（水平軸心を中心として）「閉位置」と「開位置」との間で回転自在となされている。前記ボール弁体１２には、「開位置」において両弁座１０を連通させる貫通孔１３が形成されている。なお、云うまでもないが、ボール弁体１２が図示の状態から９０度回転して、「閉位置」に位置すると、ボール弁体１２によって両弁座１０は閉塞される。   A valve casing 8 is housed and fixed inside the portion of the pipe body 3 where the opening 6 is formed. The valve casing 8 is composed of a pair of upper and lower valve casing halves 9 spaced apart from each other in the axial direction of the pipe body 3. An annular valve seat 10 made of a synthetic resin or the like centering on the axis of the pipe body 3 is provided in each of the mutually opposite portions of the valve casing half 9, and a ball valve body 12 is provided on the valve seat 10. The ball valve body 12 is brought into contact with the tube body 3 so as to be rotatable between a “closed position” and an “open position” about an axis perpendicular to the axis of the tube body 3 (centering on the horizontal axis). ing. The ball valve body 12 is formed with a through hole 13 for communicating the valve seats 10 in the “open position”. Needless to say, when the ball valve body 12 rotates 90 degrees from the illustrated state and is positioned at the “closed position”, both valve seats 10 are closed by the ball valve body 12.

前記上の弁ケーシング半体９、ボール弁体１２及び下の弁ケーシング半体９が、上下方向に並び、且つ、相互に隣接するもの同士が密接する状態となされ、その状態で上の弁ケーシング半体９、ボール弁体１２及び下の弁ケーシング半体９が上下に動かないようにするための上下一対の欠環状のスナップリング１６が、管本体３の内周面に形成された環状溝１５に嵌め止められている。なお、弁ケーシング半体９の外周部には環状溝１７が形成され、この環状溝１７に環状パッキン１８が嵌め止められている。   The upper valve casing half 9, the ball valve body 12, and the lower valve casing half 9 are arranged in the vertical direction and adjacent to each other are in close contact with each other. An annular groove formed on the inner peripheral surface of the pipe body 3 is a pair of upper and lower cut-off snap rings 16 for preventing the half body 9, the ball valve body 12 and the lower valve casing half body 9 from moving up and down. 15 is fixed. An annular groove 17 is formed in the outer peripheral portion of the valve casing half 9, and an annular packing 18 is fixed to the annular groove 17.

前記膨出部５に弁体作動部材２０が嵌められている。前記弁体作動部材２０は、短円柱状の本体２２と、この本体２２の右端に突設された係合突片２３と、本体２２の左端に突設された、開口６に嵌まった状態の円板状の突起２４とを有している。   A valve body actuating member 20 is fitted into the bulging portion 5. The valve body actuating member 20 is fitted into a short columnar main body 22, an engagement protrusion 23 protruding from the right end of the main body 22, and an opening 6 protruding from the left end of the main body 22. Disc-shaped protrusion 24.

前記本体２２の外周部には環状溝２６が形成され、この環状溝２６に環状パッキン２７が嵌められている。前記係合突片２３は、ボール弁体１２に形成された凹所２９に嵌まっていて、弁体作動部材２０の回転（水平軸心を中心とする回転）に伴ってボール弁体１２が回転するようになされている。前記突起２４にはドライバー挿入用の溝３０が形成されている。   An annular groove 26 is formed in the outer peripheral portion of the main body 22, and an annular packing 27 is fitted in the annular groove 26. The engagement protrusion 23 is fitted in a recess 29 formed in the ball valve body 12, and the ball valve body 12 is rotated along with the rotation (rotation around the horizontal axis) of the valve body operating member 20. It is designed to rotate. The protrusion 24 is formed with a groove 30 for inserting a driver.

前記弁体作動部材２０、弁ケーシング８及びボール弁体１２の組み立て方法を以下に説明する。
まず、弁体作動部材２０を膨出部５に嵌める。
その後、下のスナップリング１６を下の環状溝１５に嵌め、次いで、下の弁ケーシング半体９、ボール弁体１２、上の弁ケーシング半体９を順次、管本体３に嵌め、その後、上のスナップリング１６を上の環状溝１５に嵌める。
なお、ボール弁体１２を管本体３に嵌める際、係合突片２３を凹所２９に嵌めることは云うまでもない。 A method for assembling the valve element actuating member 20, the valve casing 8, and the ball valve element 12 will be described below.
First, the valve body operating member 20 is fitted into the bulging portion 5.
Thereafter, the lower snap ring 16 is fitted into the lower annular groove 15, and then the lower valve casing half 9, the ball valve body 12, and the upper valve casing half 9 are sequentially fitted to the pipe body 3, and then the upper The snap ring 16 is fitted into the upper annular groove 15.
Needless to say, when the ball valve body 12 is fitted into the pipe body 3, the engagement protrusion 23 is fitted into the recess 29.

以下に変形例等について説明を加える。
（１）弁体はボール弁体１２以外であってもよい。
（２）弁ケーシング８の構造も図示ものに限定されない。 A description will be given below of modifications and the like.
(1) The valve body may be other than the ball valve body 12.
(2) The structure of the valve casing 8 is not limited to the illustrated one.
