Description

A safety valve air intake device Technical Field

[0001] This utility model relates to the field of safety valve technology, specifically to a safety valve air inlet device. Background Technology

[0002] Safety valves are important safety accessories for boilers, pressure vessels and other pressure equipment. In modern industrial production, the requirements for safety performance are getting higher and higher. A safety valve is a special valve that is normally closed under the action of external force. When the pressure of the medium in the equipment or pipeline rises to exceed the specified value, it prevents the pressure of the medium in the pipeline or equipment from exceeding the specified value by discharging the medium to the outside of the system.

[0003] A search revealed that patent application number 201320069729.5 discloses a safety valve air intake device, including a safety valve body, an air intake pipe, a sealing element disposed on the air intake pipe, an air intake hole on the sealing element, and an isolation layer fixedly connected to the air intake pipe, with a small hole in the center of the isolation layer. This invention uses the small hole in the center of the isolation layer to perform preliminary filtration of the gas, ensuring that the gas entering the air intake hole does not contain large particulate impurities. The relatively large diameter of the air intake hole ensures the smooth flow of gas into the safety valve body, and it has the advantages of simple structure and reliable air intake method.

[0004] In existing technologies, the intake pipe and safety valve generally use a spiral connection. However, this traditional connection method has obvious drawbacks: First, the sealing structure of the spiral connection is easily affected by factors such as assembly process and material deformation, posing a risk of gas leakage, which in turn leads to a decrease in the pressure monitoring and release accuracy of the safety valve; Second, during long-term use, the spiral connection is prone to corrosion due to repeated stress and environmental factors, which not only reduces the connection strength but also seriously affects the overall performance and service life of the safety valve, increasing equipment maintenance costs and safety hazards.

[0005] Therefore, we propose a safety valve air intake device. Summary of the Invention

[0014] The air plate and its air groove are designed to clear the fluid flowing through them, ensuring that airflow is injected into the safety valve.

[0015] As a preferred embodiment of this utility model, the top side of the air plate is provided with an air groove and a slot, and the sealing assembly is fitted with a filter plate through the slot. The filter plate is a truncated disc.

[0016] The filter disc is designed to be easily installed in the air plate, making it easy to disassemble and replace.
