Claims

[Scope of utility model registration request]

Fluid is blown out from the upstream side (-next side) of the valve body 2 into the main diaphragm chamber 3 in response to fluctuations in the downstream pressure (secondary pressure) of the pressure reducing valve body 2 interposed in the middle of the fluid pipe 1. The self-blade pressure reducing pressure regulator is configured to generate a driving pressure for opening and closing the valve body 2 by relatively changing the amount of fluid leaking from the main diaphragm chamber 3. The main diaphragm chamber 31 is connected to an auxiliary diaphragm chamber 6 via a throttle 4 and a capacity tank 5, and the diaphragm 7 of this auxiliary diaphragm chamber 6 is caused by fluctuations in secondary pressure accompanying opening and closing operations of the valve body 2. A pressure regulator for a self-cutting pressure reducing valve, characterized in that it is configured to apply a force in the direction of reducing the force to a pair of diaphragms 8.9 forming the main diaphragm chamber 3.
