Background technique
At present, along with the continuous progress of conveying technology and the growing tension of petroleum resources, the combustion gas of low-pressure such as rock gas, biogas progressively enters in the daily life, the single energy in city is just progressively broken by multipotency source supply system, the steam line of connecting coal gas, rock gas, liquid gas, biogas equal energy source in same family has simultaneously become possibility, and people can use according to the combustion gas that the market price changes and the selection of air feed situation is suitable.With the fuel gas heating apparatus is example, be the structure of single liquid gas special use or rock gas special use in the past, because the calorific value difference of various combustion gas, the air pressure of its output, tolerance must have difference, must at first determine employed source of the gas when therefore the user buys, select suitable product according to source of the gas then, so, on the one hand when the user need change usefulness gas kind, just must buy new combustion gas tool again, or undergo technological transformation, cause the waste of customer investment increase and social resources, produced a difficult problem also on the other hand the product dealer, can't estimate the quantity of certain kind combustion gas tool, tend to occur a kind and overstock the phenomenon that another kind is out of stock.Meanwhile, concerning a kind of family, generally maximum may be to have the possibility maximum of two kinds of sources of the gas, if can design a kind of gas appliance that can satisfy two kinds of sources of the gas of use simultaneously, then can satisfy most users' needs substantially, and will realize this purpose, its key is that a kind of energy of design satisfies the pressure regulator valve that two kinds of combustion gas are used, and according to the knowledge of the applicant, still do not have a kind of pressure regulator valve that can be used for two kinds of combustion gas uses at present and can select for use for the user.
Summary of the invention
The purpose of this utility model is wide in variety at present gas source, and same fuel gas heating apparatus need use two kinds of combustion gas and not have the problem that suitable pressure regulator valve can Gong be selected for use, designs a kind of pair of pressure pressure maintaining valve.
The technical solution of the utility model is:
A kind of pair of pressure pressure maintaining valve, comprise valve seat 1, valve casing 2, spool 3, rubber valve plate 4, pressure adjusting spring 5, adjusting pressuring knob 6, rubber valve plate 4 is installed between valve seat 1 and the valve casing 2 and will be divided into common pressure chamber 7 and pressure stabilizing cavity 8 by the inner chamber that valve seat 1 and valve casing 2 are connected to form, valve casing 2 is provided with the vent 12 that communicates with common pressure chamber 7, it is characterized in that on described valve seat 1, being provided with two inlet holes 9, on the hole wall of each inlet hole 9, be provided with the regulator hole 10 that communicates with pressure stabilizing cavity 8, be provided with two pressure adjusting spring seats 11 at valve casing 2 with respect to the position of inlet hole 9, adjusting pressuring knob 6 spinnings are in pressure adjusting spring seat 11, pressure adjusting spring 5 is installed in the pressure adjusting spring seat 11, one end and adjusting pressuring knob 6 offset, one end of the other end and spool 3 offsets, the other end that has the conical surface of spool 3 passes rubber valve plate 4 and stretches in the regulator hole 10 on inlet hole 9 hole walls, and gas outlet 13 is positioned on the valve seat 1 and with pressure stabilizing cavity 8 and communicates.
One in described two inlet holes 9 is the high pressure gas inlet, and another is the low-pressure gas inlet.
Described pressure stabilizing cavity 8 is separated into high pressure pressure stabilizing cavity and low-pressure pressure stabilizing cavity by dividing plate 14, and they all communicate with gas outlet 13.
The utlity model has following advantage:
1, for two combustion gas users have solved a use difficult problem, mixes the change that relevant parts such as nozzle can be realized usefulness gas mode again, only need change corresponding intake interface during replacing and get final product.
2, make things convenient for the dealer and the manufacturing enterprise of combustion gas articles for use, be convenient to organize production and selling.
3, simple in structure, purposes is wide, not only can be used for fuel gas heating apparatus, and can be used for the kitchen tools product, as kitchen range, gas water-heater etc.
4, applicable to various combustion gas, only should be noted that during installation that combustion gas that calorific value is higher relatively and the relatively low combustion gas of calorific value are distinguished, connect according to product descritption and get final product, safe and reliable.
5, delivery pressure can be adjusted according to the kind demand of combustion gas, and pressure keeps stablizing constant in the output procedure.
Description of drawings
Fig. 1 is a perspective view of the present utility model.
Fig. 2 is that internal structure of the present utility model is cutd open and shown schematic representation.
Embodiment
Following structure drawings and Examples are further described the utility model.
As shown in Figure 1, 2.
The two pressure pressure maintaining valves of a kind of fuel gas heating apparatus, comprise valve seat 1, valve casing 2, spool 3, rubber valve plate 4, pressure adjusting spring 5, adjusting pressuring knob 6, rubber valve plate 4 is installed between valve seat 1 and the valve casing 2 and will be divided into common pressure chamber 7 and pressure stabilizing cavity 8 by the inner chamber that valve seat 1 and valve casing 2 are connected to form, valve casing 2 is provided with the vent 12 that communicates with common pressure chamber 7, on described valve seat 1, be provided with two inlet holes 9 (as Fig. 1), on the hole wall of each inlet hole 9, be provided with the regulator hole 10 that communicates with pressure stabilizing cavity 8, be provided with two pressure adjusting spring seats 11 at valve casing 2 with respect to the position of inlet hole 9, adjusting pressuring knob 6 spinnings are in pressure adjusting spring seat 11, pressure adjusting spring 5 is installed in the pressure adjusting spring seat 11, one end and adjusting pressuring knob 6 offset, one end of the other end and spool 3 offsets, the other end that has the conical surface of spool 3 passes rubber valve plate 4 and stretches in the regulator hole 10 on inlet hole 9 hole walls, gas outlet 13 is positioned on the valve seat 1 and with pressure stabilizing cavity 8 and communicates, pressure stabilizing cavity 8 can be separated into high pressure pressure stabilizing cavity and low-pressure pressure stabilizing cavity by dividing plate 14, but they must communicate with gas outlet 13, also can have the through hole that is communicated with high pressure pressure stabilizing cavity and low-pressure pressure stabilizing cavity on the dividing plate 14.
Two 9 one of inlet holes connect the high pressure combustion gas, and another connects the low-pressure combustion gas, when the calorific value of two kinds of combustion gas is more or less the same, also can be one and connects the higher relatively combustion gas of calorific value that another connects the relatively low combustion gas of calorific value.
Working principle of the present utility model is:
As shown in Figure 2, when having combustion gas to feed in high (low) calorific value fuel gas suction port 9, the regulator hole 10 of combustion gas from its hole wall enters the pressure stabilizing cavity 8 and to rubber valve plate 4 and produces an active force, promptly promoting spool 3 after rubber valve plate 4 is stressed moves to the direction of pressure adjusting spring 5, if the elastic force of pressure adjusting spring 5 and the active force of rubber valve plate offset, then spool 3 keeps different, be that delivery pressure is a setting pressure, when suction pressure becomes big (little), pressure phase strain in the pressure stabilizing cavity 8 big (little), the pressure that acts on the rubber valve plate 4 becomes big (little), then rubber valve plate 4 drive elastic force that spools 3 overcome pressure adjusting spring 5 upwards (descend) mobile, because the effect of the conical surface of the other end of spool 3, make the aperture of regulator hole 10 diminish (greatly), thereby make the gaseous-pressure that enters in the pressure stabilizing cavity 8 descend (rising), the pressure that guarantees gas outlet 13 is all the time within range of set value.
