at present Oil cylinder manufacturer Self powered Lifting valve Because it does not need other external energy sources such as power and gas, it is driven only by the energy of the medium itself, which is energy-saving, environmentally friendly and easy to use; Moreover, the automatic operation can be realized when the pressure value is set after installation, so the self operated lifting valve has been widely used in various industrial departments in China.
However, in order to put the self operated lifting valve into normal operation, it must be ensured that its installation and use are correct. Now let's talk about the correct installation and use of the self operated lifting valve on the steam pipe.
1. When installing the self operated regulating valve above the steam pipe, a condensation tank must be added between the actuator and the pipe to prevent steam from entering the actuator diaphragm head;
2. The self operated lifting valve must be installed head down, and the condensation tank must be higher than the membrane head. For the first use, the condensation tank and membrane head must be filled with water; In order to ensure the normal operation of the regulating valve, the joint must not leak, and the condensate tank must not be short of water. Regular inspection is required, and water should be added at the right time.
3. If the steam pressure is high, it is better to choose a piston actuator rather than a diaphragm actuator. Since the pressure that the diaphragm can withstand generally does not exceed 0.4Mpa, although it can be used, it will greatly reduce the service life.
4. For the maintenance personnel of self operated lifting valve, they must pay more attention and check frequently to prevent accidents.
