Abstract
The utility model relates to a compression natural gas pressure reducing regulator for an automobile, a pressure reducing chamber consists of a primary pressure reducing chamber and a secondary pressure reducing chamber, wherein the secondary pressure reducing chamber is provided with a pressure-regulating device which comprises a secondary spring regulating screw and a secondary spring regulating gland, and the pressure regulating device can regulate the pressure of the secondary pressure reducing chamber within the pressure range of 1.5 to 2.6 bar. The utility model is under secondary pressure reducing, has simpler structure and less cost, directly and sequentially jets the natural gas into a cylinder to be mixed with air, can be suitable for more automobiles, can supply the air flow required by an engine at any condition, can regulate the secondary pressure, is suitable to be conveniently installed under the condition that when the engine power is less than 145KW, a low pressure air outlet is parallel with the primary pressure reducing chamber and the secondary reducing chamber, and can supply enough flow, stable pressure to the engine of the automobile, thereby the acceleration performance of the automobile can be completely reflected, and the starting power is perfectly represented.
Description
Technical field
The utility model relates to a kind of decompressor, relates in particular to a kind of automobile compressed natural gas pressure reducing regulator that adopts second depressurized.
Background technique
Existing home and overseas because energy scarcity and oil can not be regenerated, adds the modern industry fast development, the energy scarcity aggravation.Automobile power Fuel Demand and the variation of automobile power fuel are just extremely urgent.
Automotive fuel is generally diesel oil, gasoline or rock gas at present, and other automobile power energy costs such as solar energy and electric energy are too high, are unfavorable for popularizing, and diesel oil, gasoline contamination are serious, and the rock gas clean environment firendly.So the utilization of rock gas just becomes the first-selected automobile power energy.Gas-fueled vehicles all use the canned rock gas of compression, and before entering motor car engine, compressed natural gas all will be through the decompressor decompression, and this decompressor is automobile compressed natural gas pressure reducing regulator.Present rock gas pressure reducing regulator, be generally three grades of decompressions, as the patent No. is the Chinese patent " automobile compressed natural gas pressure reducing regulator " of ZL 2,007 20081141.6, such pressure reducing regulator is installed on the automobile and miscellaneous part, electric fittings constitute automotive fuel natural gas supply system jointly, is that mixer is installed on air intake branch.Air and rock gas are entered motor after the mixing in advance on request, and the ratio of rock gas and air mixing can not be fully guaranteed, and make automobile bigger at the power loss that uses rock gas, and the pressure of decompression chamber can not be regulated.
The model utility content
The purpose of this utility model just is to provide a kind of new automobile compressed natural gas pressure reducing regulator that adopts second depressurized and decompression chamber's pressure to regulate within the specific limits.
To achieve these goals, the technical solution adopted in the utility model is such: comprise high pressure admission threeway, safety valve, decompression chamber and low pressure air outlet, described decompression chamber is made of one-level decompression chamber and second depressurized chamber, described second depressurized chamber is provided with pressure regulator, the two-level spring adjustment gland that described pressure regulator is adjusted screw by two-level spring and placed two-level spring to adjust the screw lower end is formed, and described pressure regulator can be adjusted the pressure of second depressurized chamber in the pressure range of 1.5-2.6bar.
As preferably: described low pressure air outlet is parallel to one-level decompression chamber and second depressurized chamber.
Compared with prior art, advantage of the present utility model is: the utility model is a second depressurized, structure is simpler, reduce cost, adopt rock gas directly to spray in order behind the cylinder and air mixing, suitable vehicle is wider, can be provided at the desired tolerance of motor under any condition, can regulate secondary pressure simultaneously, secondary pressure is regulated arbitrarily between 1.5-2.6bar, be applicable to that engine power is below the 145KW, the low pressure air outlet is parallel to one-level decompression chamber and second depressurized chamber, and convenient the installation is for motor car engine provides sufficient flow, pressure stable, the automobile acceleration performance finds full expression, perfect reproduction start power.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment 1:
Referring to Fig. 1 and Fig. 2, the utility model comprises high pressure admission threeway 1, safety valve 2, circulating water joint 3, one-level decompression chamber 4, second depressurized chamber 5 and low pressure air outlet 6.
Wherein, three interfaces of high pressure admission threeway 1 connect the compressed natural gas pipe respectively, i.e. suction tude, and another connects pressure gauge, also has one to be connected with pressure reducing regulator.
Safety valve 2 is positioned at one-level decompression chamber 4 outer left side of face, one-level decompression chamber 4 is parallel combined with second depressurized chamber 5, cover plate 9 on both shared diaphragms 10 and the diaphragm is respectively equipped with the adjusting of reducing pressure of one-level spring 11 and two-level spring 12 in one-level decompression chamber and the second depressurized chamber.
Be provided with pressure regulator in second depressurized chamber 5 upper ends, the two-level spring adjustment gland 8 that pressure regulator is adjusted screw 7 by two-level spring and placed two-level spring to adjust the screw lower end is formed, and pressure regulator can be adjusted the pressure of second depressurized chamber 5 in the pressure range of 1.5-2.6bar.
Two circulating water joints 3 are in a plane, promptly adopt 180 degree around mode, not only be convenient to install circulating pipe, and can prevent effectively that more stagnant ice blocks up.
Low pressure air outlet 6 is parallel to one-level decompression chamber 4 and second depressurized chamber 5, greatly facilitates installation.
During use, compressed natural gas through one-level inlet valve seat and one-level valve port, enters one-level relief chamber 4 by high pressure admission threeway 1, through the I and II passage, the secondary valve port enters second depressurized chamber 5 again, through low pressure air outlet 6, be connected again, enter motor again with combustion gas spray rail.
All joints adopt all that tightness detects under fabulous sealing material, first-class accessory processing technique and the 25Mpa pressure in the utility model, have guaranteed that durable nothing leaks.
The utility model is a second depressurized, structure is simpler, reduce cost, adopt rock gas directly to spray in order behind the cylinder and air mixing, suitable vehicle is wider, can be provided at the desired tolerance of motor under any condition, simultaneously can regulate secondary pressure, secondary pressure is regulated arbitrarily between 1.5-2.6bar, is applicable to that engine power is below the 145KW, and the low pressure air outlet is parallel to one-level decompression chamber and second depressurized chamber, the convenient installation, for motor car engine provides sufficient flow, pressure stable, the automobile acceleration performance finds full expression, perfect reproduction start power.
