Safety type QTYH-15 1/2 inch Throttle element pressure relief check
valve Pressure Relief Valve
Description
Pressure relief valve is a valve that can automatically maintain
stable outlet pressure by adjusting the inlet pressure to a
required outlet pressure and relying on the energy of the medium
itself.
Application
The pressure reducing valve is a valve that adjusts the inlet
pressure to a certain required outlet pressure and relies on the
energy of the medium itself to automatically maintain the outlet
pressure. From the point of view of fluid mechanics, the pressure
reducing valve is a throttling element whose local resistance can
be changed, that is, by changing the throttling area, the flow
velocity and the kinetic energy of the fluid are changed, resulting
in different pressure losses, thereby achieving the purpose of
decompression. Then, relying on the adjustment of the control and
regulation system, the fluctuation of the post-valve pressure is
balanced with the spring force, so that the post-valve pressure
remains constant within a certain error range.
Ordering Code
Principle
The pressure reducing valve adopts the opening degree of the
opening and closing member in the control valve body to adjust the
flow rate of the medium, reduce the pressure of the medium, and
adjust the opening degree of the opening and closing member by the
action of the pressure behind the valve, so that the pressure
behind the valve is maintained within a certain range. Inside, the
cooling water is sprayed into the valve body or behind the valve to
lower the temperature of the medium. This type of valve is called a
vacuum desuperheating valve.
Pressure relief valve quick and easy automatic selection is
included. The valve is characterized by keeping the outlet pressure
and temperature within a certain range in the case of constant
changes in inlet pressure.

| It reduces the high liquid pressure in the front line of the valve
to the level required in the back line of the valve. |
Function
1. Reduced water waste and rationalized system flow distribution,
improved system layout and operating conditions
2.Simple structure and easy disassembly.
3. Reliable quality and low failure rate.
Fault phenomenon: unstable pressure fluctuation
Failure analysis:
1. Air is mixed into the oil. Damping holes are sometimes blocked
3. The roundness of the spool and the valve body exceeds the
specified value, causing the valve to become stuck
4. The spring is deformed or stuck in the spool, making the slide
move difficult or the spring is too soft
5. The steel ball is not round, the steel ball is not well matched
with the valve seat or the poppet valve is not installed correctly.
