When shutting off the flow of fluid, it is used as a shut-off valve when controlling the opening and closing of the flow path, and as a check valve when shutting off the back flow of fluid.

これらのバルブとして、弁箱内に弁座が設けられ、該弁座に対して弁軸に支持された弁体が当接、離反するようになっているバルブがある。かかるバルブにあっては、一般に、１つの弁座と、該弁座に対して当接、離反する１つの弁体が設けられた構造となっている。（例えば、特許文献１参照。）。   As these valves, there is a valve in which a valve seat is provided in a valve box, and a valve body supported by a valve shaft contacts and separates from the valve seat.

In addition, the valve box 1 is provided with a plunger receiving plate 23 that restricts the movement of the plunger 21 in the direction of the valve body 11 so that the weight of the plunger 21 is not applied to the valve body 11 when the electromagnetic coil 19 is not energized.

このような構成のバルブによれば、遮断時に、弁座６を構成する小径の弁座部６ａと大径の弁座部６ｂに、弁体１１を構成する小径の弁体部１１ａと大径の弁体部１１ｂが当接し、２段シールを行うので遮断性が向上し、そして、前記小径の弁座部６ａはゴム等の弾性材料で形成され、前記大径の弁座部６ｂは金属等の剛性材料で形成されており、他方、これらに当接する小径の弁体部１１ａは金属等の剛性材料で形成され、前記大径の弁体部１１ｂはゴム等の弾性材料で形成されているので、小径の弁座部６ａと小径の弁体部１１ａとの間にゴミ等が挟まれて遮断が不完全になったとしても、ゴム等の弾性材料で形成されている小径の弁座部６ａが変形することにより大径の弁座部６ｂと大径の弁体部１１ｂが確実に当接し、或いは、大径の弁座部６ｂと大径の弁体部１１ｂとの間にゴミ等が挟まれて遮断が不完全になったとしても、ゴム等の弾性材料で形成されている大径の弁体部１１ｂが変形することにより小径の弁座部６ａと小径の弁体部１１ａが確実に当接し、これにより流路４の遮断が確保され、確実な遮断性が得られる。   According to the valve having such a configuration, the small-diameter valve body portion 11a constituting the valve body 11 and the large-diameter valve seat portion 6b are separated from the small-diameter valve seat portion 6a and the large-diameter valve seat portion 6b constituting the valve seat 6 when shut off. Since the valve body portion 11b contacts and performs two-stage sealing, the blocking performance is improved, and the small-diameter valve seat portion 6a is made of an elastic material such as rubber, and the large-diameter valve seat portion 6b is made of metal. On the other hand, the small-diameter valve body portion 11a that is in contact with these is formed of a rigid material such as metal, and the large-diameter valve body portion 11b is formed of an elastic material such as rubber. Therefore, even if dust or the like is sandwiched between the small-diameter valve seat portion 6a and the small-diameter valve body portion 11a and the shut-off is incomplete, the small-diameter valve seat formed of an elastic material such as rubber is used. Due to the deformation of the portion 6a, the large-diameter valve seat portion 6b and the large-diameter valve body portion 11b abut securely, or the large-diameter Even if dust or the like is sandwiched between the valve seat portion 6b and the large-diameter valve body portion 11b and the shut-off is incomplete, the large-diameter valve body portion 11b formed of an elastic material such as rubber is used. By deforming, the small-diameter valve seat portion 6a and the small-diameter valve body portion 11a are surely brought into contact with each other, whereby the blockage of the flow path 4 is ensured and a reliable blocking property is obtained.

また、前記ゴム等の弾性材料で形成されている小径の弁座部６ａの小径の弁体部１１ａとの当接面は同心状に環状に突設された線状突起部９を備えているので、前記小径の弁座部６ａの当接面に備えた線状突起部９に小径の弁体部１１ａが当接したとき、線接触となり、線状突起部９の接圧が高まり、遮断性を一層向上させることができる。   Further, the contact surface of the small-diameter valve seat portion 6a formed of an elastic material such as rubber with the small-diameter valve body portion 11a is provided with a linear projection portion 9 that is concentrically protruded in an annular shape. Therefore, when the small-diameter valve body portion 11a comes into contact with the linear projection portion 9 provided on the contact surface of the small-diameter valve seat portion 6a, line contact occurs, and the contact pressure of the linear projection portion 9 increases, thereby blocking. Property can be further improved.

また、前記弁軸１０の先端には球面体１４が一体に設けられ、該球面体１４に前記弁軸１０に嵌合した筒状の弁体支持体１２の先端部が揺動自在に支持され、該弁体支持体１２に前記弁体１１が支持されているので、弁軸１０の先端で弁体１１が自由に向きを変えることができ、弁体１１を確実に弁座６に当接させることができる。   A spherical body 14 is integrally provided at the distal end of the valve shaft 10, and a distal end portion of a cylindrical valve body support 12 fitted to the valve shaft 10 is swingably supported by the spherical body 14. Since the valve body 11 is supported by the valve body support body 12, the direction of the valve body 11 can be freely changed at the tip of the valve shaft 10, and the valve body 11 is reliably brought into contact with the valve seat 6. Can be made.
