Pneumatic valve 4L210-08 Hand control valve 5/2way 0-0.8Mpa Manual valve
Application
The manual valve is the control part in the pipeline fluid transportation system. It is used to change the channel section and the flow direction of the medium. It has the functions of diversion, cut-off, regulation, throttling, check, diversion or overflow pressure relief. For the valve used for fluid control, the nominal diameter of the valve is from the extremely small instrument valve to the industrial pipeline valve with the diameter up to 10 m. Under the action of pressure, temperature or other sensing signals, the valve can act according to the predetermined requirements, or simply open or close without depending on the sensing signals. The valve depends on the driving or automatic mechanism to make the opening and closing parts move up and down, slide, swing or rotate, so as to change the size of its flow passage area to realize its control function.
Principle
Rotate the adjusting screw clockwise, adjust the spring force and press the diaphragm downward, and move the connecting spool and chassis downward. At this time, a path is formed above the spool chassis, and the air pressure is exported through the outlet.
When the outlet pressure rises to the set pressure, it is transmitted to the bottom of the diaphragm through the outlet pressure sensing hole, and the spring pressure is balanced, and the set pressure is maintained.
When the outlet pressure is greater than the set pressure, it is transmitted to the bottom of the diaphragm through the outlet pressure induction hole, and the hole between the diaphragm and the chassis opens. The outlet pressure is transmitted to the spring chamber through the hole and discharged to the atmosphere to maintain the set pressure.
