EXPLOSION-PROTECTIVE VALVE FOR PROCESS EQUIPMENT Russian patent published in 2012 - IPC F16K17/40 F16K17/16 F16K17/12 

FIELD: mechanics.

SUBSTANCE: invention relates to mechanical engineering and is intended for explosion protection of process equipment. In the explosion-protective valve comprising valve body, valve, heat insulating and discontinuous elements, there is additionally lined cargo bolt. This cargo bolt is movably connected to the valve body by at least three flexible connectors, such as chains. One end of the chain is pivotally connected to the valve body. The other end is pivotally connected to the cargo bolt. The valve body is designed as bottom cylindrical, middle conical and upper cylindrical parts. In the bottom cylindrical part the lined cargo bolt that overlaps the hole on the protected object is placed. In the upper cylindrical part of the valve bode the insulation and sealing membrane is placed. The membrane is pressed against the valve body through the lid. The lid is pivotally connected with a lever coupled to the striker. Attachment point of the burst element is mounted on the lever by its upper part and to the upper cylindrical part of the valve body by its bottom part. The burst element consists of wire, locking bolt, plug, valve led lever, nuts, two drums, located respectively in the plug of the valve lid lever and in the plug of the upper cylindrical part of the valve body. The ends of the wire are inserted into the drums holes and then are wound up on them.

EFFECT: improved protection efficiency of the process equipment from explosions by increasing the speed and reliability of operation.
