Sleeve spring type safety relief Valves
Safety Relief of the Sleeve Spring Type In order to balance the force acting on the disc, valves utilise the force of the compression spring. By rotating the adjustment nut on the helical coil spring, the amount of compression can be changed. With this arrangement, the safety valve's opening (set) pressure can be adjusted as necessary.
Sleeve Spring Type Safety Relief Valves
Sleeve Spring Type Safety Relief Valves use the force of the compression spring to balance the force acting on the disc. The compression amount of the helical coil spring can be adjusted by turning the adjusting nut on it. With this structure, the opening (set) pressure of the safety valve can be corrected as required.
The advantages of Sleeve Spring Type Safety Relief Valves
Sleeve Spring Type Safety Relief Valves are light and compact in structure, relatively high in sensitivity, unlimited in installation position, and less sensitive to vibration, so they can be used on mobile pressure vessels.
The precautions of Sleeve Spring Type Safety Relief Valves
1. When the Sleeve Spring Type Safety Relief Valves leave the factory, no set pressure and constant pressure are shipped from the factory. It is recommended that you complete the constant pressure on site;
2. Sleeve Spring Type Safety Relief Valves only play the role of overvoltage protection system, and the accuracy of stabilizing pressure is not high. It is strictly forbidden to use safety valves in the occasion of controlling system pressure;
3. For the Sleeve Spring Type Safety Relief Valves that have not been used for a period of time, the initial unloading pressure will be higher than the set pressure of the valve, and it will return to normal after several times of opening and closing.
The working principle of Sleeve Spring Type Safety Relief Valves
Sleeve Spring Type Safety Relief Valves are automatically opened and closed according to the working pressure of the pressure system, and are generally installed on equipment or pipelines in closed systems to protect the safety of the system. When the pressure in the equipment or pipeline exceeds the set pressure of the safety valve, it will automatically open the pressure relief to ensure that the medium pressure in the equipment and pipeline is below the set pressure, protect the normal operation of the equipment and pipeline, prevent accidents and reduce losses.
