Description

Technical Field

[0001] The utility model relates to the technical field of safety valves, in particular to a safety valve. Background Art

[0002] A safety valve is a safety protection valve. Its opening and closing parts are in a normally closed state under the action of external forces. When the medium pressure in the pen or pipeline increases and exceeds the specified value, it automatically opens and discharges the medium outside the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value. Safety valves are automatic and are mainly used in boilers, pressure vessels and pipelines to control the pressure not to exceed the specified value, playing an important protective role in personal safety and equipment operation.

[0003] A safety valve disclosed in the Chinese utility model patent application publication specification CN219655359U includes: a locking mechanism installed on a gas valve body, a rotating valve capable of rotating on the gas valve body, a limiter provided on the rotating valve, and a locking mechanism capable of locking and fixing the limiter. One of the limiter plates on the rotating valve is inserted into the interior of the limiter slot, so that two limiter holes are aligned with two threaded holes, and two screws are screwed so that the lower ends of the screws can pass through the limiter holes and abut against the interior of the slot, so that the rotating valve can be effectively limited and locked, further increasing the safety of the use of the gas valve body. Although the above device fixes the valve through the locking mechanism to ensure the stability of the valve opening and closing size, the above device ignores the impact of external objects on the valve body, and the impact of the external environment on the valve body will also damage the normal operation of the valve body. Secondly, the above device is exposed to the outside world for a long time and is more susceptible to corrosion by various external elements, which will reduce the service life of the valve body.
