Further, in order to preferably realize the present invention, the power below outlet pressure increase, Small diaphragm-piece is more than regulation bullet The elastic force of spring, Small diaphragm-piece are moved up, and secondary flap moves to closing direction, and the gas for making to enter below big diaphragm is reduced, main valve Valve aperture reduces, and outlet pressure declines and reaches balance.
Further, in order to preferably realize the present invention, the automobile fuel gas electric control operation valve includes adjusting screw, regulation Spring, Small diaphragm-piece, secondary flap, main valve clack, big diaphragm, adjusting screw are connected through the top cover of valve seat with regulation spring, adjust bullet The lower end of spring is connected by Small diaphragm-piece with secondary flap, and secondary flap is connected by spring with main valve clack, and the lower end of main valve clack is connected with Connecting tube, connecting tube are connected with big diaphragm, and the regulation spring, Small diaphragm-piece, secondary flap, main valve clack, big diaphragm are respectively positioned on valve seat It is interior.
Further, in order to preferably realize the present invention, chamber where the secondary flap is from upper end and big diaphragm institute position Chamber in valve seat lower end.
Further, in order to preferably realize the present invention, chamber that the main valve clack, connecting tube, big diaphragm are located at Chamber isolation where secondary flap (4), and connected by communicating pipe (4).
The present invention compared with prior art, has the following advantages and advantages:
The inlet pressure of fluid is lowered and is automatically held in a certain needs by the technical program by using the principle of throttling Outlet pressure regulating valve, pressure-reducing valve is mainly used in steam supply, supply, water supply and oil supply system.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention;
Wherein:1- adjusting screws 2-regulation 3-Small diaphragm-piece of spring, 4-secondary flap, 5-main valve clack, 6-big diaphragm, 7- Valve seat, 8-laminate pipe, 9-communicating pipe, 10-valve seat.
Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, with reference to embodiment, the present invention is made Further to describe in detail, exemplary embodiment of the invention and its explanation are only used for explaining the present invention, are not intended as to this The restriction of invention.
Embodiment 1:
As shown in figure 1, a kind of operating method of automobile fuel gas electric control operation control valve, including adjusting screw 1, regulation spring 2nd, Small diaphragm-piece 3, secondary flap 4, main valve clack 5, big diaphragm 6, adjusting screw 1 are connected with regulation spring 2 through the top cover of valve seat 10, adjusted The lower end of section spring 2 is connected by Small diaphragm-piece 3 with secondary flap 4, and secondary flap 4 is connected by spring with main valve clack 5, main valve clack 5 Lower end is connected with connecting tube 8, and connecting tube 8 is connected with big diaphragm 6, it is described regulation spring 2, Small diaphragm-piece 3, secondary flap 4, main valve clack 5, Big diaphragm 6 is respectively positioned in valve seat 10.
Wherein, the chamber where the secondary flap is located at the chamber of valve seat lower end from upper end and big diaphragm.
Wherein, the chamber that the main valve clack 5, connecting tube 8, big diaphragm 6 are located at completely cuts off with the chamber where secondary flap 4, And connected by communicating pipe 4.
Turn adjusting screw 1 and open secondary flap 4, combustion gas enters the lower section of big diaphragm 6, and the big movement of diaphragm 6 opens main valve clack 5 Open, gas into the lower section of Small diaphragm-piece 3, adjusts outlet pressure simultaneously.
When outlet pressure increase, the power of the lower section of Small diaphragm-piece 3 is more than the elastic force of regulation spring 2, and Small diaphragm-piece 3 moves up, secondary Flap 4 is moved to closing direction, and the gas for making to enter the big lower section of diaphragm 6 is reduced, and the aperture of main valve clack 5 reduces, and outlet pressure declines And reach balance.
During concrete operations:Turn adjusting screw and open secondary flap, gas enters the big Xia Fang ﹐ of diaphragm 6 because big diaphragm 6 is (or living Plug) (or downwards) is mobile upwards after area ﹐ stress bigger than main valve clack 5 opens main valve clack 5 to open ﹐ fluids by exporting also while entering Then outlet pressure is gradually increased to required numerical value to the Xia Fang ﹐ of Small diaphragm-piece 3.At this moment gas is acted on Small diaphragm-piece 3 total power with The elastic force Xiang Ping Heng ﹐ flap positions for adjusting spring 2 keep constant.Such as outlet pressure Zeng Gao ﹐ because the power of the lower section of Small diaphragm-piece 3 is more than tune The Dan Li ﹐ Small diaphragm-pieces 3 of section spring 2 are to make to enter the big lower section of diaphragm 6 to closing direction Yun Dong ﹐ therewith Xiang Shang Yi Dong ﹐ secondary flaps 4 Fluid subtracts few ﹐ pressure and ﹐ is also dropped under then the aperture of main valve clack 5 subtracts small ﹐ outlet pressures and also reaches new balance therewith declining. The aperture Zeng great ﹐ outlet pressures of anti-﹐ outlet pressures Xia Jiang Shi ﹐ main valve clacks 5 rise again.Zhe Yang ﹐ outlet pressures are automatically kept Within prescribed limit.
Above-described embodiment, the purpose of the present invention, technical scheme and beneficial effect are carried out further Describe in detail, should be understood that the embodiment that the foregoing is only the present invention, be not intended to limit the present invention Protection domain, within the spirit and principles of the invention, any modification, equivalent substitution and improvements done etc., all should include Within protection scope of the present invention.
