What is safety valve seal
The safety valve seal refers that wearing the detachable or adjustable place of the safety valve with a copper wire, and then fixing it at the two ends of the copper wire with a lead block. The purpose is to prevent abnormal opening and destroy the factory state or the already-deployed security (standard) state. When used, the seal damage indicates that the safety valve may not be able to perform its safety protection and should be adjusted until it recovers. The difference between safety valve lock and seal
The seal is usually sealed after the test, and after sealing, it is not allowed to change the opening pressure without the safety valve check qualification. The lock is generally required when there is a stop valve at the entrance to the library, which needs to be locked, for fear that someone will shut the stop valve and cause an accident.
