Description
Technical field
The utility model relates to fuel gas transmission fields, more particularly to a kind of pressure regulator.
Background technique
The maximum function of natural gas pressure regulating device, which is to maintain combustion gas when in use, stable pressure, to guarantee gas appliance
Obtain stable fuel air ratio (mixing ratio of combustion gas and air)；Gas pressure is reduced using pressure regulator in fuel gas supply system
And stablizing can make gas obtain safety, on the economic and proper level that efficiently utilizes at one, pressure regulator output pressure can
Range is adjusted, requires to reach defined precision within this range, the rod-type as described in application publication number CN105443830A file
Pressure regulating device, wherein；Voltage regulation diaphragm between the shell and the pressure regulator membrane cover is set, is arranged in the voltage regulation diaphragm
Pressure spring between the pressure regulator membrane cover, the lever being connected with the voltage regulation diaphragm, the pressure in P2 as shown in Figure 1
Power is adjusted by pressure spring 32 and is adjusted, and instantaneous pressure is excessive in P2 to be adjusted.
Summary of the invention
Purpose of the invention is to overcome the deficiencies of the prior art and provide that a kind of structure is simple, safe and reliable pressure regulator,
Including valve body；It is characterized in that the valve body is to be divide into upper part and lower part, top is mainly by pressure chamber, rubber membrane, connector, film
Piece, the first spring, second spring composition；Lower part includes air inlet, gas outlet, adjusting rod, water conservancy diversion cavity, the pressure chamber with lead
It is separated between stream cavity using rubber membrane, described adjusting rod one end is connect with connector；The adjusting rod other end and diversion cavity
Body connection, the adjusting rod jag are connect with air inlet one end；The gas outlet is connect with water conservancy diversion cavity, the diaphragm side
It is connect with second spring, the diaphragm side is connect with pressure chamber, due to rubber membrane pair during air pressure transient rise and shakiness
The elastic module for determining air pressure is limited, increases pressure chamber's diaphragm, and when increasing air pressure moment, diaphragm generation type, which becomes, reduces in pressure chamber
Pressure makes pressure chamber pressure more tend to stationary value to supply gas.
Further, the pressure regulation bar is threadedly coupled with valve body top, long-term spring type is become and elastic failure
A kind of compensation.
Further, further include the adjusting rod fixed point to connector distance with fixed point to water conservancy diversion cavity apart from lever
Than for 7:1, effective lever arm can effectively switch the air-suction state between pressure chamber and air inlet.
Beneficial effect；Pressure regulator increases diaphragm and second spring compared with prior art, the diaphragm when increasing air pressure moment
Generation type, which becomes reduction pressure room pressure, makes pressure chamber's air pressure more tend to stationary value.
Detailed description of the invention
Such as Fig. 1 pressure regulator schematic diagram in the prior art；
Such as Fig. 2 pressure regulator schematic diagram；
Shell 1, pressure regulator membrane cover 2, lever pressure regulating device 3, voltage regulation diaphragm 31, pressure spring 32, lever 33, pressure regulator
Valve rod 34；
Valve body 1a, top 11, lower part 12, air inlet 2a, gas outlet 3a, pressure chamber 4, rubber membrane 41, connector 42, diaphragm
43, the first spring 5, second spring 52, pressure regulation bar 51, adjusting rod 6, water conservancy diversion cavity 7.
Specific embodiment
Valve body 1a as shown in Figure 2 is to be divide into upper part and lower part, and top 11 is mainly by pressure chamber 4, rubber membrane 41, connector
42, diaphragm 43, the first spring 5, second spring 52 form；Lower part 12 includes air inlet 2a, gas outlet 3a, adjusting rod 6, diversion cavity
Body 7 is separated between the pressure chamber 4 and water conservancy diversion cavity 7 using rubber membrane 41, and described 6 one end of adjusting rod and connector 42 connect
It connects；6 other end of adjusting rod is connect with water conservancy diversion cavity 7, and 6 jag of adjusting rod is connect with the one end air inlet 2a；It is described
Gas outlet 2a is connect with water conservancy diversion cavity 7, and 43 side of diaphragm is connect with second spring 52,43 side of diaphragm and pressure chamber
4 connection, pressure regulation bar 51 is threadedly coupled with valve body top 11 be adjusted second spring 52 come realize adjusting pressure chamber 4 air pressure
Value.
When combustion gas contributes to air inlet 2a by main pipeline, since main pipeline air pressure is greater than water conservancy diversion cavity 7, lead in the prior art
Pipeline gas enters that the pressure regulator time is all very short, and once at 1 second, rubber membrane 41 and diaphragm 43 will be under pressure simultaneously, rubber membrane
41 are connect by connector 42 and adjusting rod 6,41 one end of rubber membrane with the first spring 5, and the elastic force of the first spring 5 makes to adjust
Folding relationship is formed between 6 one end of bar and air inlet 2a, makes at the 3a of gas outlet pressure mean values in required value section.
When main pipeline air pressure is excessive, prevent type between rubber membrane 41 and the first spring 5 from becoming excessive influence its gas outlet 3a
Pressure and service life reduce water conservancy diversion cavity 7 wherein deformation occurs with second spring 52 in 7 one latallae 43 of water conservancy diversion cavity
Interior pressure, cooperation adjusting rod fixed point 61 to 42 distance of connector are 7:1 apart from lever ratio with fixed point 61 to water conservancy diversion cavity 7,
Reach test optimum value.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
