Description
【０００１】[0001]
この考案は真空槽の隔離壁の開口部に着座する矩形逆耐圧仕切弁に関するもの である。 The present invention relates to a rectangular reverse pressure sluice valve that is seated in the opening of the isolation wall of a vacuum chamber.
【０００２】[0002]
従来の矩形逆耐圧仕切弁は図６および図７に示されており、これらの図におい て、真空槽１の隔離壁１ａには長方形の開口部２が縦長に設けられ、その開口部 ２近傍の左下方の隔離壁１ａの位置には軸受３が固定され、また、真空槽１の天 板１ｂにも軸受４が固定され、軸受３と軸受４とで弁棒５が支承されている。弁 棒５には２つのアーム６が上下に取り付けられ、更に、その２つのアーム６の先 端には弁体７が取り付けられ、その弁体７が開口部２近傍の隔離壁１ａの弁座に 着座できるようになっている。矢印は弁体７が弁座に着座しているとき、弁体７ に逆圧が作用する方向を示している。 A conventional rectangular reverse pressure sluice valve is shown in FIGS. 6 and 7, and in these drawings, a rectangular opening 2 is provided vertically in a partition wall 1a of a vacuum chamber 1, and the vicinity of the opening 2 is provided. A bearing 3 is fixed to the position of the isolation wall 1a at the lower left of the above, and a bearing 4 is also fixed to the ceiling plate 1b of the vacuum chamber 1, and a valve rod 5 is supported by the bearing 3 and the bearing 4. Two arms 6 are vertically attached to the valve rod 5, and a valve element 7 is attached to the front ends of the two arms 6, and the valve element 7 is attached to the valve seat of the isolation wall 1 a near the opening 2. It is possible to sit on. The arrow indicates the direction in which the counter pressure acts on the valve body 7 when the valve body 7 is seated on the valve seat.
【０００３】 なお、図中、８は弁棒５を回転させる回転駆動機構である。In the figure, 8 is a rotary drive mechanism for rotating the valve rod 5.
【０００４】 このような矩形逆耐圧仕切弁において、回転駆動機構８により弁棒５を回転さ せ、弁体７を弁座に着座させる。弁体７が弁座に着座しているとき、弁体７には 矢印に示される方向より逆圧が作用するようになる。In such a rectangular reverse pressure gate valve, the rotary drive mechanism 8 rotates the valve rod 5 to seat the valve body 7 on the valve seat. When the valve body 7 is seated on the valve seat, the counter pressure acts on the valve body 7 in the direction indicated by the arrow.
【０００５】[0005]
従来の矩形逆耐圧仕切弁は、弁棒５を回転させて、弁体７を弁座に着座させる ようにしているが、弁体７が弁座に着座しているとき、弁体７には逆圧が作用す るので、弁座における弁体７のシール性が悪くなる問題があった。また、弁棒５ の回転により、アーム６と弁体７とが回転して、弁体７が弁座に着座するように なっているので、弁体７が大きい場合にはた回転半径が大きくなり、仕切弁の専 有空間が大きくなる等の問題があった。 In the conventional rectangular reverse pressure gate valve, the valve rod 5 is rotated so that the valve body 7 is seated on the valve seat. However, when the valve body 7 is seated on the valve seat, Since the counter pressure acts, there is a problem that the sealing performance of the valve body 7 at the valve seat deteriorates. Further, the rotation of the valve rod 5 causes the arm 6 and the valve body 7 to rotate, so that the valve body 7 is seated on the valve seat. Therefore, when the valve body 7 is large, the turning radius is large. Therefore, there was a problem that the exclusive space of the gate valve became large.
【０００６】 この考案の目的は、従来の上記問題を解決して、弁体に逆圧が作用しても、弁 体のシール性が悪くならず、仕切弁の専有空間を小さくすることの可能な矩形逆 耐圧仕切弁を提供することである。The object of the present invention is to solve the above-mentioned problems of the prior art, and even if a back pressure acts on the valve element, the sealing performance of the valve element does not deteriorate, and the space occupied by the gate valve can be reduced. It is to provide a rectangular reverse pressure proof gate valve.

上記目的を達成するために、この考案は、真空槽の隔離壁に設けられた矩形の 開口部近傍の弁座に矩形の弁体を着座させる矩形逆耐圧仕切弁において、上記矩 形の弁体を上記隔離壁に沿って上記矩形の開口部付近にまで移動可能な移動手段 と、上記矩形の開口部近傍の弁座に上記矩形の弁体を着座させたうえ、上記矩形 の弁体を上記弁座側に押圧する押圧手段とを備えたことを特徴とするものである 。 In order to achieve the above object, the present invention relates to a rectangular reverse pressure sluice valve in which a rectangular valve body is seated on a valve seat near a rectangular opening provided in an isolation wall of a vacuum chamber. A moving means that is movable along the isolation wall to near the rectangular opening, and the rectangular valve element is seated on the valve seat near the rectangular opening, and the rectangular valve element is It is characterized by comprising a pressing means for pressing the valve seat side.

Further, since the rectangular valve element is seated on the valve seat near the rectangular opening and the pressing means for pressing the rectangular valve element to the valve seat side is provided, even if a back pressure acts on the valve element. The sealing property of the gate valve does not deteriorate.

An embodiment of the present invention is shown in FIGS. 1 to 5. First, in FIGS. 1 and 2, a rectangular opening 2 is provided in a vertical direction in a partition wall 1a of a vacuum chamber 1, and the opening 2 A rectangular valve body 7 is seated on the valve seat of the isolation wall 1a in the vicinity of 2. In the vicinity of each long side of the rectangular valve body 7, two rotary shafts 10 are arranged along each long side. Four eccentric cams 11 are fixed to each of the two rotary shafts 10 at equal intervals, and by rotating the two rotary shafts 10, each eccentric cam 11 is rotated, and the rectangular valve body 7 is rotated by each eccentric shaft. The cam 11 presses the isolation wall 1a toward the valve seat side. 3 to 5, a guide 12 is fixed to the isolation wall 1a of the vacuum chamber 1 above the opening 2 in parallel with the short side of the opening 2 and guided horizontally by the guide 12. A rectangular valve body 7 is attached to the lower end of the arm 13. A rack 14 is attached to the upper end of the arm 13, and the rack 14 meshes with the pinion 15. The pinion 15 is connected to the pinion rotary drive 16. Further, a rotary actuator 17 is attached to the upper ends of the two rotary shafts 10, and the rotary actuators 17 rotate the two rotary shafts 10, respectively. The arrow indicates the direction in which the counter pressure acts on the valve body 7 when the valve body 7 is seated on the valve seat.
【００１０】 このような実施例において、ピニオン用回転駆動機１６でピニオン１５を回転 させると、これと歯合するラック１４が直線運動し、その直線運動に伴ってアー ム１３がガイド１２によって水平方向に案内され、長方形の弁体７が開口部２の 近傍に移動させられる。その後、ロータリーアクチュエーター１７により、２つ の回転軸１０がそれぞれ回転し、その回転に伴って偏心カム１１も回転し、偏心 カム１１が長方形の弁体７を隔離壁１ａの弁座側に押圧して、仕切弁のシール性 がよくなる。なお、弁体７を隔離壁１ａの弁座より離す場合には、上記手順と逆 にすればよい。In such an embodiment, when the pinion rotary drive 16 rotates the pinion 15, the rack 14 meshing with the pinion 15 linearly moves, and the arm 13 is horizontally moved by the guide 12 along with the linear motion. Guided in the direction, the rectangular valve element 7 is moved to the vicinity of the opening 2. After that, the two rotary shafts 10 are respectively rotated by the rotary actuator 17, and the eccentric cam 11 also rotates in accordance with the rotation, and the eccentric cam 11 presses the rectangular valve body 7 toward the valve seat side of the isolation wall 1a. As a result, the sealing property of the gate valve is improved. When the valve body 7 is separated from the valve seat of the isolation wall 1a, the above procedure may be reversed.
