Transient rise if P1, P2 will then increases, the diaphragm chamber pressure within 6, initiation of thrust on the diaphragm may increase, the thrust mutilate the balance of the original force, mobile diaphragm 5 progresses, there are less local 12, exhaust air flow through the overflow hole eye discharge. 。 Gas reduced pressure valve are: straight acting by pressure valves and pilot operated by two kinds of pressure valve, understanding to reduce gas pressure valve, the user can reduce the starting pressure valve office principle through gas. Office principle a: q: low gas pressure valve reduce pressure valve is mainly used for gas pipeline, such as air, nitrogen, hydrogen and other gases, it mainly office after adjusting the spring pressure setting outlet pressure, outlet pressure changes in the use of diaphragm sensor, after this after a pilot valve opening and closing drive piston to adjust the main valve throttle, so successful implementation effect. Straight acting to reduce the pressure valve work principle of compressed air for P1, from left side input after 10 throttling valve, pressure drop for P2 output. The P2 volume can be adjusted by elements of the regulating spring 2, 3. Straight acting principle of reducing pressure valve office it with straight acting basically the same. If the input pressure transient current, output pressure is decreased, the diaphragm down 5, 8 with the valve core down, intake valve 10 big open mouth, throttling utility decreases, and the output pressure is also the basic back to its original value. The knob counterclockwise 1, relax the regulating spring 2, 3, gas utility of thrust is greater than the pressure regulating spring on diaphragm 5 for Marine valve, diaphragm aspirant, rely on the utility of the reset spring close the inlet valve opening 10. In the diaphragm up at the same time, because of the utility of the reset spring 9, 8 also makes the Industrial Valves core progressive movement, turning down the intake valve opening 10, throttling utility increase, make the output pressure loss, until reaching a new equilibrium as output pressure basic back to the original value. When the distance between the nozzle, and the baffle is subtle change occurs, will cause the pressure in the room B very superficial changes, so the boot 10 have larger displacement of diaphragm, and 6 to curb the valve core to move up and down, the inlet valve mouth 8 up or down, rose to alert degree of the valve core stem, which increase the voltage regulation precision. The knob clockwise 1, compression spring, 2, 3, 8 down and diaphragm may make the valve core, Industrial Valves mouth opening of 10 P2 increase. If reduce the small straight acting pressure valve is installed inside the body, it is called a pilot operated reducing pressure valve; If cut small straight acting pressure valve is installed on the outside of the main body, is called external guiding type reducing pressure valve. 1 if counterclockwise rotation knob, opening of valve port 10 is reduced, the P2 is less. Pilot operated out of decrease the pressure valve regulating body, is provided by a small straight acting to reduce pressure valve. And straight by acting to reduce the pressure valve, the valve is increased by the nozzle, 4, 3, 9 and fixed orifice gas damper chamber B of the nozzle flapper amplification. Through above straight acting to reduce pressure valve principle and guiding type office office principle of reducing pressure valve, we can be more clear understanding to the gas reduced pressure valve office conditions, as this kind of product use range increasing in our country, to speed up the development of this kind of products is of great significance. Rotate knob 1 again, the top of the inlet valve core 8 4 will release with the overflow valve seat, diaphragm chamber via the overflow hole 12, six of compressed air exhaust eye discharge, make the valve in the output.
