本発明は、電磁弁に取り付けた安全弁に関し、特に危険
ガス、有毒ガス等特殊ガス配管の安全機構に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a safety valve attached to a solenoid valve, and particularly to a safety mechanism for special gas piping such as dangerous gas or toxic gas.
従来技術を図を用いて説明する。第３図が従来の電磁弁

−クローズタイプ）電磁弁である。The conventional technology will be explained using figures. FIG. 3 is a sectional view of a conventional solenoid valve, and what is shown is a normally closed type solenoid valve.

よって８の流体は弁座部にて遮断される。In FIG. 3(a), the electromagnet 6 is in an OFF state, and the elastic force of the spring in the cylinder 4 pushes the piston 3 toward the valve seat 2. The piston number 3 has a magnetic disk number 7 and a number 1
The valve seat seal is attached, and the valve seat and valve seat seal are pressed down by the force of the spring. As a result, the fluid No. 8 is shut off at the valve seat.

できる。In FIG. 3(b), the electromagnet is in the on state, and the magnetic disk 7 is attracted to the electromagnet. At this time, the piston of 3 is 5
The valve seat seal 1 is lifted up against the elastic force of the spring 2, and the valve seat seal 1 is separated from the valve seat 2. Therefore, the fluid of 8 can pass through the valve seat.
上述した従来の電磁弁では、電磁石がｏｆｆの状態では
弁座が閉じて流体を遮断する構造（ノーマリークローズ
）となっていた。The conventional electromagnetic valve described above has a structure (normally closed) in which the valve seat closes to shut off fluid when the electromagnet is off.

た。Malfunctions of solenoid valves used in special gas piping, such as when the electromagnet part shorts out and becomes welded to the cylinder, or when the valve seat and valve seat seal stick together and cannot be separated by the magnetic force of the electromagnet. In this case, the solenoid valve must be replaced. However, if the piping is clogged with dangerous gas, this dangerous gas will leak into the atmosphere when the solenoid valve is replaced, making it very dangerous.

In addition to the general solenoid valve structure consisting of a piston and valve seat with a valve seat seal and a magnetic disc, we have: 1) A structure in which a female thread is cut outward from the valve seat part, and a male thread that matches the female thread is cut. It has a structure in which the stem is inserted into the valve seat, a structure in which a handle is attached to the outside of the stem, and a structure in which a cap nut is attached to seal the stem threaded portion from the outside.

There is a structure in which an external container having an inner diameter slightly larger than the diameter of the plate is attached to an external pedestal via a sealing material, a structure in which a sealing material is attached between the disk and the inner wall of the external container, and an external container. It has a structure in which a joint for compressed air piping is attached to a position facing the disc, and a structure in which an air vent hole is provided in a position close to the attachment part of the external container.
本発明の実施例を図面を参照して説明する。 Embodiments of the present invention will be described with reference to the drawings.
第１図は本発明の第１の実施例の断面図である。FIG. 1 is a sectional view of a first embodiment of the invention.

つけられる（以上電磁弁の構造）。The valve seat seal 1 is connected to the piston 3 together with the magnetic disk 7. This piston is housed in a cylinder 4 via a spring 5, and around the cylinder there are 6
An electromagnet is attached. When the electromagnet is turned on, the magnetic disk 7 is pulled by the magnetic force, and therefore the piston 3 moves up inside the cylinder against the elastic force of the spring 5. This causes the valve seat and valve seat seal to separate. On the other hand, when the electromagnet is turned off, the valve seat seal is pressed against the valve seat by the elastic force of the spring (the above is the structure of the electromagnetic valve).
弁座部は外部−向りてメネジが開けられておシ、ここに

る。The valve seat part has a female thread facing outward, and a stem number 9 with a male thread that matches the female thread is inserted here. Ten handles are attached to the end of the stem. A cap nut 11 prevents fluid from flowing from the valve seat through the stem and mixing with the outside atmosphere.
今、電磁弁の故障、もしくは停電等のトラブルが発生し
たとすると、弁座と弁座シールとは互いに押しつけられ
、流体は弁を通過できず、配管内に流体がとじ込められ
る。If a problem such as a failure of the solenoid valve or a power outage occurs, the valve seat and valve seat seal will be pressed against each other, preventing fluid from passing through the valve and trapping the fluid in the piping.
この状態で１０のハンドルを回すと、９のステムは上昇
し、１の弁座シールを持ち上げるので、流体は弁を通過
できるようになる。When the handle 10 is turned in this state, the stem 9 rises and lifts the valve seat seal 1, allowing fluid to pass through the valve.
〔実施例２〕 第２図は本発明による第２の実施例の断面図である。[Example 2] FIG. 2 is a sectional view of a second embodiment according to the invention.

材が取り付けられている。A hole is made from the valve seat part 2 toward the pedestal 15 on the outside, and the stem 9 is inserted into the hole. Twelve springs are attached to the pedestal side of the stem, and thirteen discs are attached to the end. The external container 14, which has an inner diameter slightly larger than the diameter of the disk, is attached to the pedestal 15 via a sealing material (16), and the valve seat fluid passes through the stem to the outside. Prevents leakage. 17 joints are attached to the portions of the 14 external containers facing the discs, and 18 compressed air pipes are further connected to these joints. Additionally, 19 air vent holes are provided near the base of this external container. Furthermore, 16 sealing materials are attached between the disk and the inner wall of the external container.
今、電磁弁の動作が何らかの原因で停止したとすると、
流体は弁座部を通過できなくなる。この状態で１８の圧
縮空気配管に高圧空気を導入すると、１３の円板は圧力
差によって押し上げられる。Now, suppose that the solenoid valve stops operating for some reason.
Fluid will no longer be able to pass through the valve seat. When high pressure air is introduced into the compressed air pipe 18 in this state, the disc 13 is pushed up due to the pressure difference.
それに伴ってステムが上昇して弁座シールを持ち上げる
ので、流体は再び流れることができるようになる。The stem then rises and lifts the valve seat seal, allowing fluid to flow again.
尚、本実施例では高圧空気によってステムを駆動するの
で遠隔操作が可能であるという利点がある。In this embodiment, since the stem is driven by high-pressure air, there is an advantage that remote control is possible.
以上説明したように本発明は弁座側に、弁座シール部を
弁座から引き離すことが可能なステムを有することによ
シ、電磁弁の交換の際のガス抜き作用、および停電時に
電磁弁の動作が失われた時のガス抜き作用が可能になる
という効果がある。As explained above, the present invention has a stem on the valve seat side that is capable of separating the valve seat seal portion from the valve seat. This has the effect of making it possible to release gas when the operation is lost.
