The emergency unloading valve (safety valve) is a direct-acting self-resetting valve. Its release mechanism is a spring-loaded ball and ball seat structure. When the pressure exceeds the set value, it will automatically overflow, realizing automatic protection of personal safety and high-pressure systems. The top adjustment bolt can adjust the release pressure from 35MPa to 140MPa. When the pressure in the system exceeds the preset value, the valve automatically opens to release the pressure by relying on the pressure of the system itself; after the pressure drops to the normal value, the valve stem resets under the action of the spring, and the safety valve automatically closes. Ensure personal safety and equipment.
The high-pressure safety valve produced and sold by our company Huichi petro is forged with high-quality alloy structural steel. It is a device to protect equipment and personal safety, usually installed on cementing, fracturing pumps, high-pressure operation pipelines, pressure vessels, and equipment operating under high pressure and high flow conditions.
1. The internal disc spring is used to realize the automatic opening and closing of the valve, which can provide overpressure protection without stopping the machine, and its performance is better than that of the shear pin safety valve;
2. The safety valve has a simple structure and a small size; it adopts a union connection method, which is easy to install and disassemble;
3. There is no leakage under normal circumstances;
4. The function of the high-pressure safety valve in the remote control console is to protect the equipment from damage due to overpressure operation;
5. There are no frequently replaced wearing parts, the pressure regulation is stepless and accurate, and the unloading pressure can be adjusted at will;
6. The product implementation standard is API-6A, and the connection form and specifications are consistent with the specifications of similar products of other companies, and similar products have strong interchangeability.
