What is the role of Anhui electric hydraulic butterfly valve in HVAC? How to distinguish the function of electric ball valve? There are three items as follows:
1. Leakage problem The action principle of the electric ball valve is angular travel, double-sided sealing, good sealing performance, not easy to leak. The operating principle of the solenoid valve is straight stroke, diaphragm or pilot type. The sealing face has very high requirements for the purity of the medium, and impurities in the medium will simply cause leakage.
2. The orientation of the device requires that the electric ball valve has no requirements for the device's viewpoint. The solenoid valve is a straight stroke action principle, and the sealing needs to be completed by the force of the gravity of the valve core and the electromagnet, so the solenoid valve can only be installed horizontally, and other sight devices will cause the leakage of the solenoid valve.
3. Service life The electric ball valve actuator will be powered off by the internal microswitch after the switch action is in place, and it has the function of working position persistence. It only needs to be powered on when the action is in place, and the motor will not be electrified after the action is in place. Its service life is longer than that of the solenoid valve, and its performance is stable. The opening and closing of the solenoid valve can only be operated by energizing the coil. When the station persists, the coil needs to be energized all the time (for example, the normally closed solenoid valve needs to be opened for a long time). The coil will heat if it is electrified for a long time, which simply causes the coil to burn out. This is a common problem
、 Generally speaking, the technology of electric butterfly valve is often reflected in its electric part, and its production requirements in this respect will naturally decline when users use it, which will lead to the decline of its quality in many aspects. Another aspect is that it should also meet high material requirements during production, Because the seal sample on the product is often related to its material.
