QFRH-25 High Pressure Filter Pressure Reducing Valve
Description
The pressure relief valve of compressed air filter adopts rolling
diaphragm. When the pressure at the input end fluctuates, the
diaphragm of the pressure relief valve automatically adjusts to
make the pressure output stable and ensure the pressure stability.
Application
The combined filter pressure relief valve can select high precision
pressure relief valve according to the requirement of output
pressure precision. In the process of using, the compressed air can
be removed oil, water, dust and other impurities in the compressed
air through two-stage and three-stage filters, which greatly
improves the service life of the valve diaphragm and the precision
of regulating pressure. The service life of the filter element is
longer, and the filter element and the decompression element can be
repaired separately in maintenance, without the need for overall
replacement, which greatly saves the cost.
Ordering Code
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.
