China's independent research and development of ammonia emergency fill-off valve to fill the gap

A new type of valve product developed by ammonia to absorb the advantages of many valves with emergency shut-off valves combines the advantages of globe valves, check valves, solenoid valves and pneumatic valves. It has the features of simple structure, responsiveness, and reliable operation.

The emergency shut-off valve for ammonia is a product of a senior engineer retired from the Ministry of Technology on the basis of years of design experience and on-site practical inspection. Most of the valves of the pipe network system are mainly used to cut off and regulate the medium. This part of the valve is The proportion and weight of the system account for a large proportion, requiring a large number of valves, requiring the valve to be durable and cost-effective. At the same time, it should be able to adjust and load when the medium is flowing forward. It can also prevent the reverse flow of the medium when the pressure difference is changed or overhauled. Features.

Installed on liquid ammonia, gas or gas pipelines, and used with gas source [nitrogen gas-free air], using gas source control valves to open and close so that when leakage or even fire occurs on pipelines or storage tanks, workers quickly pass through them. Remote solenoid valve or manual pressure relief, or high temperature ≥ 80 °C (fusible alloy) melting, and the cylinder automatically pressure relief, the valve quickly closed and leak, play a role in security.
