Industrial steam safety valve

Industrial steam safety valves play a safety protection role in the system. When the system pressure exceeds the specified value, the safety valve opens and releases a portion of the gas/fluid in the system into the atmosphere/pipeline, ensuring that the system pressure does not exceed the allowable value and preventing accidents due to excessive pressure.

Industrial steam safety valve is a type of safety protection valve, whose opening and closing components are in a normally closed state under external force. When the pressure of the medium in the equipment or pipeline increases and exceeds the specified value, it automatically opens to prevent the pressure of the medium in the pipeline or equipment from exceeding the specified value by discharging the medium outside the system. Safety valves belong to the category of automatic valves, mainly used in boilers, pressure vessels, and pipelines to control pressure not exceeding the specified value, playing an important protective role in personal safety and equipment operation.

There are two main types of structures:

Spring type and lever type. Spring type refers to the sealing between the valve disc and the valve seat relying on the force of the spring.

The lever type relies on the force of the lever and heavy hammer. With the demand for large capacity, there is another type of pulse type safety valve, also known as pilot operated safety valve, which consists of a main safety valve and an auxiliary valve. When the pressure of the medium in the pipeline exceeds the specified pressure value, the auxiliary valve opens first, and the medium enters the main safety valve along the pipeline, and the main safety valve is opened to reduce the increased medium pressure.

Compressed air system with pressure protection A simple and low-cost type of component that can be directly connected to pressure vessels and related components.

A 40AC directional control component that can be installed at any node of the compressed air system.

The selection of suitable industrial steam safety valves should consider the following aspects:

1. The structural form mainly depends on the process conditions, working medium, and characteristics of the equipment. Spring type safety valves are often used when the discharge capacity of boilers and pressure vessels is not large, otherwise it is better to choose full opening safety valves;

2. If the medium is toxic, flammable and explosive, a closed safety valve should be selected;

3. Each safety valve has its own working pressure range, and the selection should be based on actual needs;

4. The discharge capacity of the selected safety valve must be greater than the discharge capacity of the equipment, in order to ensure that some media is discharged and avoid further pressure rise.
