进口电磁阀Inlet solenoid regulating valve

Product Description:

It is a common flow regulating device. Its working principle is as follows: after the coil is powered on, the fixed iron core surrounded by the coil generates magnetic force; The spring and plug head are fixed on the movable iron core. When the magnetic force of the movable iron core by the fixed iron core is greater than the elastic force of the spring, the movable iron core moves upward, the plug head leaves the valve port piece driven by the movable iron core, and the valve is in the open state; After the coil is powered off, the fixed iron core loses its magnetic force, the movable iron core resets under the elastic force of the reed, the plug seals the valve port, and the valve is closed.

进口电磁阀Features:

A cavity is arranged in the valve body; The fixed iron core and the movable iron core are fixedly arranged in the cavity, and the movable iron core can be movably arranged in the cavity; The valve seat is connected with the valve body, the valve seat is provided with a valve port piece, and the valve port piece is provided with an air inlet chamber for connecting with the external air source; The plug assembly is sealed on the valve port piece, the plug assembly is connected with the movable iron core, and the plug assembly is hermetically connected with the cavity to divide the cavity into independent upper cavity and lower cavity; The gas channel is arranged in the plug assembly, the first end of the gas channel is connected with the air inlet cavity, and the second end is connected with the upper cavity. With this arrangement, after the solenoid regulating valve is inflated, the gas in the air inlet chamber enters the upper chamber of the valve body through the gas channel in the plug assembly, so that the gas pressure in the air inlet chamber is the same as that in the upper chamber. Therefore, when the solenoid regulating valve is opened, there will be no vibration or overshoot because the pressure in the air inlet chamber is greater than that in the upper chamber, so as to ensure the stable and reliable operation of the solenoid regulating valve.

进口电磁阀Principle:

A gas channel is arranged in the plug assembly, the first end of the gas channel is connected with the air inlet cavity, and the second end is connected with the upper cavity. That is to say, as shown in Figure 2, when the solenoid regulating valve is inflated, the gas in the air inlet chamber flows upward through the gas channel and enters the upper chamber, making the air pressure in the air inlet chamber and the upper chamber equal. It does not flow downward and cannot enter the lower chamber. As the plug assembly seals the valve port, the gas can only flow in the direction indicated by the arrow in the figure, and the air inlet chamber is connected with the upper chamber through the gas channel in the plug assembly. It should be noted that the lower end of the gas channel in the figure is the first end of the gas channel, and the upper end of the gas channel in the figure is the second end of the gas channel.
