Technical Field

The invention relates to a safety valve, in particular to an explosion-proof safety valve.

Background

The safety valve is a valve for safety protection, the opening and closing part of which is in a normally closed state under the action of external force, and when the pressure of a medium in equipment or a pipeline rises and exceeds a specified value, the safety valve is automatically opened, and the medium pressure in the pipeline or the equipment is prevented from exceeding the specified value by discharging the medium to the outside of the system, so that the safety valve plays an important role in protecting personal safety and equipment operation. The safety valve process among the prior art is comparatively crude, and the case assembly reciprocates in the valve body and appears the card and hinder the phenomenon, and the leakproofness is poor between case and the disk seat, and the safety valve just leaks gas when not reaching opening pressure, has the potential safety hazard.

Disclosure of Invention

The invention provides an explosion-proof safety valve which has the advantages of simple structure, good safety, high sealing property, stable operation, long service life and sensitive reaction.

The technical scheme of the invention is as follows: the safety valve wholly be totally closed structure, the safety valve include valve cap, valve gap, valve rod, valve clack, disk seat and valve body, the valve cap setting at the safety valve top, valve cap lower part and valve gap can dismantle and be connected, connecting portion are equipped with the sealing washer, the safety valve still include the braces, the braces on be equipped with the bungee cord, bungee cord both ends connect respectively on valve cap and valve gap, institute the vertical setting of valve rod in the safety valve, the valve rod on be provided with the spring, the valve clack setting in the valve rod below, valve clack sub-unit connection disk seat, the valve body connect on the disk seat, valve body and disk seat pass through threaded connection, disk seat upper portion and valve gap can dismantle and be connected, connecting portion are provided with the sealing washer.

The invention has the advantages of simple structure, good safety, high sealing performance, stable operation, long service life and sensitive reaction.
