ストレーナ付ボールバルブは、ＬＰＧ貯蔵設備やＬＰＧ供給配管などの分野で 多用されているが、このストレーナ付ボールバルブとしては、例えば実開昭６４ −３１６２号公報に開示されたものがある。これは左右に流出入口を設け、中間 部に流入口に連通するボール収納室を設け、中間上部に弁棒貫通部を設け、弁棒 貫通部の上端にストッパーを突設し、中間下部にボール収納室と流出口とに連通 するフィルター収納室を設けた弁箱と、弁箱の弁棒貫通部の上端に螺着した蓋と 、蓋と弁箱の弁棒貫通部とを貫通する弁棒と、弁棒の上端に固定され、全開時と 全閉時に弁箱のストッパーに当接するハンドルと、弁箱のフィルター収納室に装 着したフィルターと、フィルター収納室の下端に螺着したプラグと、弁箱のボー ル収納室の左右両端に取付けた一対のシートリングと、シートリングによって挟 持され、側面から下面にわたる連通孔を有し、弁棒の下端と係合するボールとを 有するストレーナ付ボールバルブである。 その際従来のストレーナ付ボールバルブでは、弁箱のボール収納室、弁棒貫通 部及びフィルター収納室の中心線が、弁箱の流入口と流出口との中央に設けられ ており、すなわち流入口と上記中心線との間隔と、流出口と上記中心線との間隔 が等しく形成されていた。また従来のストレーナ付ボールバルブでは、全開時に はハンドルの先端に形成したストップ部と当接し、全閉時にはハンドルの側面と 当接するストッパーが、弁箱の弁棒貫通部の上端に１個だけ設けられていた。 The ball valve with a strainer is widely used in the fields of LPG storage equipment, LPG supply piping, etc. As the ball valve with a strainer, for example, there is one disclosed in Japanese Utility Model Laid-Open No. 64-3162. It has outlets on the left and right sides, a ball storage chamber in the middle that communicates with the inlet, a valve rod penetrating part in the middle upper part, a stopper protruding from the upper end of the valve rod penetrating part, and a ball in the middle lower part. A valve box provided with a filter storage chamber that communicates with the storage chamber and the outlet, a lid screwed to the upper end of the valve rod penetrating portion of the valve casing, and a valve rod penetrating the lid and the valve rod penetrating portion of the valve casing. A handle that is fixed to the upper end of the valve stem and comes into contact with the stopper of the valve box when fully opened and fully closed, a filter installed in the filter housing chamber of the valve housing, and a plug screwed to the lower end of the filter housing chamber. , A strainer having a pair of seat rings attached to the left and right ends of the ball accommodating chamber of the valve box, and a ball held between the seat rings, having a communication hole extending from the side surface to the lower surface, and engaging with the lower end of the valve rod. It is an attached ball valve. At that time, in the conventional ball valve with strainer, the center line of the ball storage chamber of the valve box, the valve rod penetrating portion and the filter storage chamber is provided at the center of the inlet and outlet of the valve box, that is, the inlet. The distance between the center line and the center line is equal to the distance between the outlet and the center line. In the conventional ball valve with strainer, only one stopper is provided at the upper end of the valve stem penetrating part of the valve box, which comes into contact with the stop part formed at the tip of the handle when fully opened and with the side face of the handle when fully closed. It was being done.

上記従来のストレーナ付ボールバルブでは、流入口より流入した流体は、ボー ルにおいて９０°転向して下方に向かい、フィルターを通過した後に流出口に向 かう。しかるに流入口と流出口とは同軸に配置されており、また上記従来のスト レーナ付ボールバルブでは、流入口とボール収納室との間隔と、フィルター収納 室と流出口との間隔が等しく形成されていたから、フィルター収納室から流出口 に向かう流路は殆ど垂直上方に近くなり、その後更に水平方向に転向して流出口 に至ることとなる。すなわちフィルターに入る流体の方向は下方であるにも拘ら ず、フィルターを出る流体は殆ど上方に向かうから、フィルターの流出入部にお いて流体の流れ方向は殆ど１８０°転向する。このために流路抵抗が大きくなり 、したがって圧力損失が大きくなり、この結果ストレーナ付ボールバルブ自体の 耐圧や管路の耐圧を高くする必要を生じ、また流体を駆動するポンプの揚程を高 くする必要を生じていた。 In the conventional ball valve with a strainer, the fluid flowing from the inflow port turns 90 ° in the ball and goes downward, and after passing through the filter, goes to the outflow port. However, the inflow port and the outflow port are arranged coaxially, and in the above conventional ball valve with a strainer, the space between the inflow port and the ball storage chamber and the space between the filter storage chamber and the outflow port are formed to be equal. Therefore, the flow path from the filter storage chamber to the outlet becomes almost vertically upward, and then it further turns horizontally to reach the outlet. That is, although the fluid entering the filter is directed downward, the fluid exiting the filter is directed almost upward, so that the flow direction of the fluid is turned about 180 ° at the inlet and outlet of the filter. For this reason, the flow path resistance increases, resulting in a large pressure loss. As a result, it becomes necessary to increase the pressure resistance of the ball valve with strainer itself and the pressure resistance of the pipeline, and also to raise the lift of the pump that drives the fluid. There was a need.
【０００４】 また上記従来のストレーナ付ボールバルブでは、弁箱の弁棒貫通部上端のスト ッパーは１個しか設けられておらず、したがってハンドルは一定の状態でしか取 り付けることができなかった。しかるにこのストレーナ付ボールバルブを使用す るＬＰＧ貯蔵設備やＬＰＧ供給配管などの分野では、同一の系統を２個用意して 両系統を切り替えて使用することが多く、したがって左右対称に配管することが 多い。この結果図４に示すように、例えば右系統では流入口を右側に配置してス トレーナ付ボールバルブＶを取付け、左系統では流入口を左側に配置してストレ ーナ付ボールバルブＶを取付けることとなる。ここで全開状態Ｏよりハンドル４ を時計方向に９０°回転させて全閉状態Ｓにするとき、右系統ではハンドル４を 手前側の開放空間に回転させて閉弁操作を行うことができるが、左系統ではハン ドル４が奥側の壁Ｗと干渉するために閉弁操作を行うことができないという問題 点があった。 したがって本考案は、流路抵抗が小さくしたがって圧力損失が小さいストレー ナ付ボールバルブを提供し、併せて壁等との干渉を回避して支障なく開閉操作を 行うことができるストレーナ付ボールバルブを提供することを目的とする。Further, in the above conventional ball valve with strainer, only one stopper is provided at the upper end of the valve rod penetrating portion of the valve box, and therefore the handle can be mounted only in a fixed state. . However, in fields such as LPG storage equipment and LPG supply piping that use this ball valve with strainer, it is common to prepare two identical systems and switch between the two systems for use, and therefore, symmetrical piping is required. Many. As a result, as shown in FIG. 4, for example, in the right system, the inlet is arranged on the right side and the ball valve V with a strainer is attached, and in the left system, the inlet is arranged on the left side and the ball valve V with a strainer is attached. It will be. Here, when the handle 4 is rotated clockwise 90 ° from the fully open state O to the fully closed state S, the handle 4 can be rotated to the front open space in the right system to perform the valve closing operation. The left system has a problem that the valve 4 cannot be closed because the handle 4 interferes with the back wall W. Therefore, the present invention provides a ball valve with a strainer that has a small flow path resistance and thus a small pressure loss, and also provides a ball valve with a strainer that can be opened and closed without interference with walls and the like. The purpose is to do.

本考案は上記目的を達成するためになされたものであり、すなわち、左右に流 出入口を設け、中間部に流入口に連通するボール収納室を設け、中間上部に弁棒 貫通部を設け、弁棒貫通部の上端にストッパーを突設し、中間下部にボール収納 室と流出口とに連通するフィルター収納室を設けた弁箱と、弁箱の弁棒貫通部の 上端に螺着した蓋と、蓋と弁箱の弁棒貫通部とを貫通する弁棒と、弁棒の上端に 固定され、全開時と全閉時に弁箱のストッパーに当接するハンドルと、弁箱のフ ィルター収納室に装着したフィルターと、フィルター収納室の下端に螺着したプ ラグと、弁箱のボール収納室の左右両端に取付けた一対のシートリングと、シー トリングによって挟持され、側面から下面にわたる連通孔を有し、弁棒の下端と 係合するボールとを有するストレーナ付ボールバルブにおいて、弁箱のボール収 納室、弁棒貫通部及びフィルター収納室を、弁箱の流入口と流出口との中央より も流入口側に片寄せて設けたことを特徴とするストレーナ付ボールバルブである 。その際、弁箱の弁棒貫通部上端のストッパーを１８０°回転対象に２個形成し 、全開時には一方のストッパーに当接し全閉時には他方のストッパーに当接する ストップ部をハンドルの先端に形成することができる。 The present invention has been made to achieve the above-mentioned object. That is, the inlet and outlet are provided on the left and right sides, the ball storage chamber communicating with the inlet is provided at the middle portion, and the valve stem penetrating portion is provided at the upper middle portion. A valve box is provided with a stopper protruding from the upper end of the rod penetrating part and a filter accommodating chamber in the lower middle part that communicates with the ball accommodating chamber and the outlet. , The valve stem that penetrates the lid and the valve stem penetrating part of the valve casing, the handle that is fixed to the upper end of the valve stem and contacts the stopper of the valve casing when fully opened and fully closed, and the filter storage chamber of the valve casing.

弁箱のボール収納室、弁棒貫通部及びフィルター収納室の中心線を、弁箱の流 入口と流出口との中央よりも流入口側に片寄せることにより、流入口とボール収 納室との間隔は短くなり、フィルター収納室と流出口との間隔は長くなる。この うち流入口からボール収納室までの間では、流体は単に直進するだけであるから 従来と特に変わりはない。しかるにフィルター収納室と流出口との間では、その 間隔が長くなったことにより、フィルター収納室出口の流路を上方に向かって形 成する必要がなくなり、斜め上方の流出口に向けて斜行した流路とすることがで きる。この結果フィルターの流出入部において流体の流れ方向は１８０°近くも 転向する必要がなくなり、したがって流路抵抗が顕著に減少して圧力損失も減少 する。 またストッパーを１８０°回転対象に２個形成したストレーナ付ボールバルブ では、開閉操作時にハンドルが壁等と干渉するときでも、ハンドルの取付け方向 を１８０°変更することにより、支障なく開閉操作を行うことができることとな る。 By aligning the center lines of the ball storage chamber, valve stem penetration and filter storage chamber of the valve box to the inlet side rather than the center of the inlet and outlet of the valve box, the inlet and the ball storage chamber are separated. The space between the filter storage chamber and the outflow port becomes longer. Among these, between the inflow port and the ball storage chamber, the fluid simply travels straight, so there is no particular difference from the conventional case. However, since the distance between the filter storage chamber and the outlet is longer, it is not necessary to form the flow path of the filter storage chamber outlet upward, and the flow path is inclined toward the upper outlet. It can be a flow path. As a result, the flow direction of the fluid does not have to be turned around 180 ° at the inflow / outflow portion of the filter, so that the flow path resistance is significantly reduced and the pressure loss is also reduced. With a ball valve with a strainer that has two stoppers that can be rotated by 180 °, even if the handle interferes with the wall during opening / closing, the handle mounting direction can be changed by 180 ° to allow opening / closing without hindrance. Will be possible.

Thus, the plug 6 holds the filter 5 in the filter storage chamber 1e. The filter 5 is fixed by pressing it toward the upper end of 1e. A pair of seat rings 7 and 7 are attached to the left and right ends of the ball storage chamber 1c of the valve box, and balls 8 are mounted between the seat rings 7 and 7, and the seat ring 7 on the inlet side is attached. Is pressed toward the ball 8 side by the retainer 9 and the insert 10, and thus the ball 8 is rotatably sandwiched by the two seat rings 7, 7. The ball 8 is formed with a communication hole 8a extending from the side surface to the lower surface thereof so as to communicate / block the inflow port 1a of the valve box and the filter storage chamber 1e. Moreover, a notch 8b is formed in the upper part of the ball 8 from the front side to the back side of the paper of FIG. 1, and a hole 8c facing the center of the ball is formed at the center bottom of the notch 8b. . The lower end of the valve rod 3 is formed in a shape that fits into the notch 8b of the ball and the hole 8c, and thus the ball 8 is configured to rotate coaxially with the rotation of the valve rod 3. There is. .
【０００９】 本実施例のストレーナ付ボールバルブＶは以上のように構成されており、弁箱 のボール収納室１ｃ、弁棒貫通部１ｄ及びフィルター収納室１ｅの中心線は、弁 箱の流入口１ａと流出口１ｂとの中央よりも流入口１ａ側に片寄せて設けられて いるから、フィルター収納室１ｅと流出口１ｂとの間隔は従来例に比較して長く なる。この結果フィルター収納室１ｅ出口の流路１ｈは、斜め上方の流出口１ｂ に向けて斜行した流路となるから、このストレーナ付ボールバルブＶの圧力損失 は従来例に比較して減少する。 いま面間寸法、すなわち流入口１ａ側フランジと流出口１ｂ側フランジとの間 隔が１１０ｍｍの製品について、流入口１ａ側フランジの端面から、ボール収納 室１ｃ、弁棒貫通部１ｄ及びフィルター収納室１ｅの中心線までの間隔を４４． ５ｍｍ、流出口１ｂ側フランジの端面から上記中心線までの間隔を６５．５ｍｍ とした製品の圧力損失を、従来例、すなわち前記中心線が流入口１ａ側フランジ の端面からも流出口１ｂ側フランジの端面からも５５ｍｍである製品の圧力損失 と比較したところ、ＣＶ値で約１２．５％の改善が得られることが解った。The strainer-equipped ball valve V of the present embodiment is configured as described above, and the center line of the ball storage chamber 1c, the valve rod penetrating portion 1d and the filter storage chamber 1e of the valve box is the inlet of the valve box. Since it is provided closer to the inlet 1a side than the center between the outlet 1a and the outlet 1b, the distance between the filter storage chamber 1e and the outlet 1b becomes longer than in the conventional example. As a result, the flow passage 1h at the outlet of the filter storage chamber 1e becomes a flow passage oblique to the flow outlet 1b located obliquely above, so that the pressure loss of the ball valve V with strainer is reduced as compared with the conventional example. Now for the product with the face-to-face dimension, that is, the gap between the inlet 1a side flange and the outlet 1b side flange of 110 mm, from the end face of the inlet 1a side flange, the ball storage chamber 1c, the valve rod penetrating portion 1d and the filter storage chamber The distance to the center line of 1e is 44. 5 mm, the pressure loss of a product in which the distance from the end face of the outlet 1b side flange to the center line is 65.5 mm is the conventional example, that is, the center line is also the outlet 1b side flange from the end face of the inlet 1a side flange. It was found that an improvement of about 12.5% was obtained in the CV value when compared with the pressure loss of the product which was 55 mm from the end face.
【００１０】 また本実施例では、弁箱の弁棒貫通部１ｄ上端のストッパー１ｆ，１ｇが１８ ０°回転対象に２個設けられている。したがって図３に示すように、例えば右系 統では図１及び図２と同様にハンドル４を取付けることにより、ハンドルのスト ップ部４ａが一方のストッパー１ｆに当接する全開状態Ｏから、ストップ部４ａ が他方のストッパー１ｇに当接する全閉状態Ｓまでの弁の開閉操作を、壁Ｗと干 渉することなく手前側の開放空間内で行うことができる。他方左系統では、スト レーナ付ボールバルブＶは右系統と対称に取付け、しかる後にハンドル４につい ては１８０°変更して右系統と同一方向に取り付けることにより、ハンドルのス トップ部４ａが他方のストッパー１ｇに当接する全開状態Ｏから、ストップ部４ ａが一方のストッパー１ｆに当接する全閉状態Ｓまでの弁の開閉操作を、同様に 壁Ｗと干渉することなく手前側の開放空間内で行うことができる。Further, in the present embodiment, two stoppers 1f and 1g at the upper end of the valve rod penetrating portion 1d of the valve box are provided for 180 ° rotation. Therefore, as shown in FIG. 3, for example, in the right system, by attaching the handle 4 in the same manner as in FIGS. 1 and 2, from the fully open state O in which the stop portion 4a of the handle comes into contact with one stopper 1f, the stop portion 4a is stopped. The valve opening / closing operation up to the fully closed state S in which 4a contacts the other stopper 1g can be performed in the open space on the front side without interfering with the wall W. On the other hand, in the left system, the ball valve with strainer V is installed symmetrically with the right system, and then the handle 4 is changed by 180 ° and installed in the same direction as the right system, so that the handle top portion 4a becomes the other. Similarly, the opening and closing operations of the valve from the fully open state O in which the stopper 1g abuts to the fully closed state S in which the stop portion 4a abuts one stopper 1f are similarly performed in the open space on the front side without interfering with the wall W. It can be carried out.
