AI Technical Summary
Existing pressure safety valves mostly rely on simple mechanical structures, such as simply relying on spring force to control the opening and closing of the valve core. When the gas pressure in the system changes suddenly and drastically, the impact force of the gas on the valve core is huge, which can easily damage the valve core, spring and valve stem, reduce service life and increase maintenance costs, and even affect system safety.
It adopts a magnetic loading buffer design, which uses a pressure monitor and an electromagnetic coil in conjunction with a magnetic sheet to monitor the gas pressure in real time and use magnetic force to control the movement speed of the valve core. Combined with a buffer plate to consume the kinetic energy of the gas flow, it reduces the impact on the valve core and valve stem. The use of stainless steel material improves stability.
This effectively avoids damage to the valve core, spring, and valve stem, improves the service life of the valve body and the stability of the system, reduces maintenance costs, and ensures the safe operation of the system.

Description
TECHNICAL FIELD
[0001] The utility model relates to pressure safety valve technical field, concretely relates to a magnetic force loading buffer type pressure safety valve. BACKGROUND
[0002] The safety valve plays a safety protection role in the system. When the system pressure exceeds the specified value, the safety valve opens, and part of the gas in the system is discharged into the atmosphere, so that the system pressure does not exceed the allowable value, thereby ensuring that the system does not have an accident due to excessive pressure. The safety valve is also called an overflow valve.
[0003] In the process of implementing the present application, it is found that the existing pressure safety valve relies on a simple mechanical structure, such as simply relying on spring force to control the opening and closing of the valve core. When the gas pressure in the system suddenly changes greatly, the impact force of the gas on the valve core is huge, directly acting on the valve core, spring and valve rod. Under frequent high pressure impact, the valve core is prone to wear and deformation, the spring elastic coefficient will gradually change, and the valve rod may be bent or even broken. This component damage problem caused by gas pressure impact not only reduces the service life of the pressure safety valve, but also greatly increases the equipment maintenance cost, and in severe cases, it may even affect the safe operation of the entire system, thus reducing the practicability of the equipment.
