Background technique
Present most of reduction valve self can only reduce pressure to a kind of source of the gas, and there are a lot of differences in the pressure of same a kind of source of the gas of different regions; Also there is pressure gap in source of the gas because of the length of transmission line; Pressure can be fluctuated in transmission course for gas, cause the combustion gas tool unsettled situation in use to occur like this, the dual gas supply reduction valve of application before our company, its application number is: 200820037780.7, it has the corresponding respectively different fuel gas source of two reduction valve and uses, but the reduced pressure capabilities of itself a little less than, can not satisfy the desired gas pressure that reduces pressure when big flow gas is imported, can not tackle the situation that the fluctuated and combustion gas tool that causes of suction pressure can not smooth working, therefore, need to produce a kind of high-flow pressure reducing valve and be applicable to two source of the gas decompressions of planting, also can make simultaneously under the situation that suction pressure constantly changes, keep atmospheric pressure in the scope of setting, thereby guarantee the proper functioning of combustion gas tool.
Summary of the invention
For solving the problems referred to above that prior art exists, the utility model proposes a kind of double gas source high-flow pressure reducing valve, it is not only applicable to the fuel gas source of different sources of the gas and is applicable to the situation that suction pressure constantly changes.
The utility model can be solved by the following technical programs:
A kind of double gas source high-flow pressure reducing valve of the utility model, it comprises a valve body, described valve body comprises two suction ports and at least one air outlet, valve body comprises that two decompression chamber are respectively first decompression chamber and second decompression chamber, be respectively equipped with decompression member in described two decompression chamber, described decompression member is divided into first space and second space of two variable sizes to described decompression chamber, and described first space and described suction port connect; The air outlet side of corresponding each described decompression chamber is established a duct respectively on the described valve body, and described duct communicates with described second space; The decompression dynamics of the decompression member in described first decompression chamber is less than the decompression dynamics of the decompression member in described second decompression chamber.
Decompression member described in the utility model comprises pressure regulation epithelium, epithelium supporting plate, pressure adjusting spring, described pressure regulation epithelium is pressed to be located between a valve gap and the valve body described decompression chamber is divided into described two spaces, and the space that described pressure regulation epithelium and described valve gap form is described second space; Establishing an aperture on the described pressure regulation epithelium makes the duct communicate with described second space with the perforation of described duct; Described pressure regulation epithelium is established a projection towards the surface of valve gap, and described epithelium supporting plate and pressure adjusting spring are located on the described projection; The elastic force of the pressure adjusting spring in described first decompression chamber is less than the elastic force of the pressure adjusting spring in second decompression chamber.
Valve outer surface described in the utility model is established an adjustment screw vertical with described duct, and penetrates in the described duct.
Owing to adopt above technological scheme, a kind of double gas source high-flow pressure reducing valve of the present utility model, the design that communicates with second space by above-mentioned duct, when the big flow gas of input, gas pressure is excessive to be flowed into above-mentioned second space and then oppresses the discharge that epithelium moves downward minimizing gas from the duct, make it reach required pressure with this further depressurized that reaches input gas.

Among the figure 1, valve gap; 2 and 7, pressure adjusting spring; 3, the epithelium supporting plate; 4, the pressure regulation epithelium; 5, adjust screw; 6, valve body; 8, the duct; 9, aperture; 10, suction port; 11, the air outlet; 12, the first decompression chamber; 13, the second decompression chamber.
Embodiment
Below in conjunction with embodiment, further set forth the utility model:
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of double gas source high-flow pressure reducing valve of the utility model, it comprises a valve body 6, valve body 6 comprises two suction ports 10 and at least one air outlet 11, valve body 6 comprises that two decompression chamber are respectively first decompression chamber and second decompression chamber, be respectively equipped with decompression member in two decompression chamber, this decompression member is divided into first and second spaces of two variable sizes to decompression chamber, and first space and suction port 10 connect; 11 sides corresponding each decompression chamber in air outlet establishes a duct 8 respectively on the valve body, and this duct 8 communicates with second space; The decompression dynamics of the decompression member in first decompression chamber is less than the decompression dynamics of the decompression member in second decompression chamber.
As an embodiment, as shown in Figure 3, above-mentioned decompression member comprises pressure regulation epithelium 4, epithelium supporting plate 3, pressure adjusting spring 2 or 7, and pressure regulation epithelium 4 is pressed to be located between valve gap 1 and the valve body 6 and decompression chamber and is divided into above-mentioned two spaces, and pressure regulation epithelium 4 is above-mentioned second space with the space that valve gap 1 forms; Pressure regulation epithelium 4 is established a projection towards the surface of valve gap, and epithelium supporting plate 3 and pressure adjusting spring 2 or 7 are located on the projection; The elastic force of the pressure adjusting spring 2 in first decompression chamber is less than the elastic force of the pressure adjusting spring in second decompression chamber 7; Establishing duct 8 on an aperture 9 and the above-mentioned valve body on the pressure regulation epithelium 4 connects the duct is communicated with above-mentioned second space.These valve body 6 outer surfaces are established an adjustment screw 5 vertical with duct 8 and are penetrated in the duct 8, can adjust the cross section in duct 8 by adjusting this adjustment screw 5, adjust the gas flow that flows into above-mentioned second space according to this.
Its working principle of reduction valve of the present utility model is: two suction ports on the valve body connect gas with various respectively, can connect rock gas, liquid gas respectively, the rock gas suction pressure enters first decompression chamber for a short time, and promotion pressure regulation epithelium 4, because pressure regulation epithelium 4 is supported by pressure adjusting spring 2, the elastic force of pressure adjusting spring 2 is fixed, so gas pressure meets when setting suction pressure, gas enters the outlet side through the gap between pressure regulation epithelium and valve body, thereby reaches the purpose of decompression.Big strength gas stream is fashionable when suction pressure surpasses the setting suction pressure, still be higher than required pressure through post-decompression gas pressure, enter above-mentioned second space through post-decompression gas by the opposite side that the aperture on the valve body flows to epithelium this moment, enter on the gas load and epithelium and epithelium supporting plate in second space, promote epithelium, reduce the air inlet gap between epithelium and the housing, thereby reach the purpose of decompression.If gas then enters second decompression chamber by suction port when being liquid gas, its decompression principle and above-mentioned rock gas are away from identical.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
