ZGQ-W solenoid valve structure analysis (self-retaining electromagnetic)

ZGQ-W Solenoid Valve Analysis: ZGQ-W solenoid valve for zero pressure and pressure pipe is an energy-saving solenoid valve, according to the use of different divided into zero pressure start and pressure start, through the double coil control. A coil control start, B coil control closed, when the A coil energized moving rod moves up into the card slot by the ball will be killed. When the B coil energized steel ball to the activities around the activities of the rod down to close the deputy valve so that the pressure difference between the upper and lower main valve to make the valve closed so as to achieve energy-saving effect ZGQ-W solenoid valve can also be installed upon request Signal feedback device can also be installed explosion-proof device. This product can be divided into a single zero-pressure self-holding and multi-function can be used for compressed air, steam, water, oil and so on. ZGQ-W solenoid valve internal structure: internal structure by the looper, piston, afterburner rod. By the ring is divided into two chambers, by the extension of the active rod is divided into two parts inside and outside. 1. Internal metal seal can be used for high temperature and pressure Internal activities can also be used to seal soft PTFE, rubber can be used for natural gas, gas, compressed air. Due to the double-layer structure, the distance between the coil and the heat source is far and at the same time, there are also ways to separate the heat pipe from the outer pipe of the ZCG solenoid valve, which greatly reduces the damage of the heat source to the coil and reduces the probability of coil burning. ZGQ-W single-body only applies to zero-pressure pipe, according to the actual needs of the choice of this product can be used to design a single zero-pressure system, the price is relatively cheap. About ZGQ-W Solenoid Valve Troubleshooting: Valve does not open: Possible coil burnout (due to long-term energization work) Check if the valve ring is damaged Medium contains solid particles in the pipe Check whether the structure of B coil is working Check for activity of ball Valve stem is not deformed Valve can not be closed: Check live A coil is power failure Check whether the piston seal is damaged or the activity of the rod is worn Check whether the ball at B is working, if not, that is, to join the oil or repair repairs
