Detailed introduction:

Network optimization information:



Three conductive solenoid valves.


Working principle: When energized, the electromagnetic force drives the pilot valve to open the pilot valve, the pressure in the upper cavity of the main valve drops rapidly, and a pressure difference is formed in the upper and lower cavities of the main valve. The closing part of the main valve is moved up by the medium pressure, and the valve opens; when the power is off , The spring force closes the pilot valve. Through the pilot hole, the inlet medium pressure quickly enters the upper cavity of the main valve, forming a pressure difference, and closing the main valve.


Features: Small size and low power, but the pressure difference range of the medium is limited, and it must meet the pressure difference condition of a certain price of the two-position three-way solenoid valve.


The so-called multi-port solenoid valve means that it usually has a spool that can slide under the electromagnetic force of the coil. When the spool is in different positions, its passages are different. This kind of solenoid valve has several working positions in the spool. This kind of solenoid valve is called a several-position solenoid valve: the number of ports on the valve body, that is, the number of ports of the solenoid valve, and the number of ports. The valves are called several solenoid valves. After the solenoid valve is installed, generally all interfaces must be connected. The so-called working position is the position of the spool. When the coil is not energized, the spool is in the A position, when the coil is energized, the spool is in the B position. When the solenoid valve spool of the gas water heater is in different positions, each interface will work, or be connected or closed.


The solenoid valve core has two different working positions (open and closed), which are called solenoid valve two positions. Two-way and three-way solenoid valves refer to two or three passage ports on the valve body of the solenoid valve; for example, a two-position two-way solenoid valve has one inlet and one outlet (two passages, the most common), two-position three-way solenoid valve The valve control liquid is one inlet and two outlets (two channels are one normally open and normally closed), the pneumatic reversing solenoid valve is one inlet, one outlet and one exhaust; the hydraulic valve is one inlet, one outlet and one oil return.
