SMC air control valves include 2, 3, and 5 ports. Taking the Japanese SMC3 vent control valve as an example, the flow direction of the medium in the Japanese SMC3 vent control valve should be consistent with the valve body
The direction of the arrow is consistent, and the external pressure pipe device must pass the pressure test before leaving the factory. It is strictly prohibited to damage the pressure pipe device during installation; The 1/2 pipe joint on the valve should be installed at the inlet of the water pump; Can be installed horizontally or vertically; When the required head of the flow limiting check valve is greater than 0.1 MPa, first open the four-way valve counterclockwise, and then gradually close the pressure regulating valve clockwise. During the closing process, the outlet pressure will gradually increase until the outlet pressure reaches the required head, which completes the initial adjustment. Repeatedly open and close the water pump 2-3 times, run for 3-5 minutes each time, and the outlet pressure remains unchanged, completing the debugging work; Depending on the water quality, the outlet pressure value should be checked regularly. When the outlet pressure is lower than the set value, the filter should be opened to remove dirt.
The Japanese SMC3 ventilation control valve is a supporting product for heating systems, widely used in electric water heaters, solar water heaters, and centralized heating water systems. And it can be matched with electric water heaters and solar water heaters. Users can adjust the temperature of the hot and cold water mixture according to their needs. The required temperature can be quickly reached and stabilized, ensuring a constant outlet temperature and not affected by changes in water temperature, flow rate, and pressure. It solves the problem of sudden changes in water temperature in the bath center. When the cold water is interrupted, the mixing valve can automatically close the hot water within a few seconds, providing safety protection.
The mixed outlet of the Japanese SMC3 ventilation control valve is equipped with a thermal sensor, which uses the characteristics of the temperature sensing element to push the valve core inside the valve body to move, block or open the inlet of cold and hot water. At the same time as blocking the cold water, turn on the hot water. When the temperature adjustment knob is set to a certain temperature, regardless of changes in the inlet temperature and pressure of the cold and hot water, the ratio of cold and hot water entering the outlet also changes accordingly, so that the outlet temperature remains constant. The temperature adjustment knob can be set arbitrarily within the specified temperature range of the product, and the constant temperature mixing valve will automatically maintain the outlet temperature.
The structure of a pneumatic control valve can be decomposed into two parts: the valve body (including the valve seat and valve hole, etc.) and the valve core. According to the relative position of the two, there are two types: normally closed and normally open. Valves can be classified structurally into three types: globe valves, sliding column valves, and sliding plate valves.
