Abstract
A pressure self-adaption multiple-air-source nozzle comprises a base and an upper cover and is characterized in that a spring locating sheet is located on a film which is installed in a film cavity formed by the upper cover and the base. The film cavity is communicated with an air inlet channel on the base. One end of a seal rod penetrates through the film to be connected with the spring locating sheet, and the lower end of the seal rod is located in an adjusting cavity. A seal ring which is matched with the lower end of the seal rod and can achieve connecting or disconnecting between the seal cavity and the film cavity is arranged in the seal cavity. The seal cavity is communicated with an air inlet cavity of an outer nozzle installed in a nozzle installation cavity, an inner nozzle is installed in the outer nozzle, and an air inlet of the inner nozzle is directly communicated with the air inlet channel arranged on the base. The pressure self-adaption multiple-air-source nozzle is simple in structure and capable of automatically opening the corresponding nozzles according to air source pressure.

At present, many sources of the gas, especially the dual gas supply gas equipment is accepted by market gradually, and it has expanded the choice of user to source of the gas widely, has made things convenient for user and manufacturing enterprise.In many sources of the gas gas equipment, need to use a large amount of selector valves to adapt to the needs of different sources of the gas, should design a manual selector valve like many (two) gas source nozzle, this design not only makes structure of nozzle complicated; Connecting pipeline increases; And can have potential safety hazard, if the user forgets or operate miss, because bleed pressure not of the same race is different; Will cause the generation of gas equipment cisco unity malfunction or security incident; To this, be necessary to design a kind of manual intervention that need not, can select respective nozzles to carry out many gas source nozzles of work automatically according to bleed pressure automatically.
Summary of the invention
The purpose of the utility model is to need manually-operated to select correct choice valve ability operate as normal to existing many gas source nozzles, causes and uses inconvenience, has the problem of potential safety hazard, designs the many gas source nozzles of a kind of pressure adaptive formula.
The technical scheme of the utility model is:
The many gas source nozzles of a kind of pressure adaptive formula; Comprise base 6 and loam cake 2, loam cake 2 is installed on the base 6, and pressure spring 14 is installed in the loam cake 2; One end and the adjusting nut 1 of pressure spring 14 offset; The other end and spring spacer 3 offset, and in the installing hole of the pressure spring 14 of adjusting nut 1 spinning on loam cake 2, it is characterized in that described spring spacer 3 is positioned on the epithelium 5; Epithelium 5 is fitted in the epithelium chamber of being made up of loam cake 5 and base 6 15; This epithelium chamber 15 is connected with inlet channel 16 on the base 6, and an end of seal bar 10 passes epithelium 15 and links to each other with spring spacer 3, and the lower end of seal bar 10 is arranged in regulates chamber 17; The sealing ring 11 that can realize annular seal space 17 and epithelium chamber 15 on-offs that matches with seal bar 10 lower ends is installed in annular seal space 17; Described annular seal space 17 is connected through the inlet chamber of the outer nozzle 8 installed in the air flue on the base 6 18 and the nozzle installation cavity 19, in described outer nozzle 8, inner nozzle 7 is installed, and the air inlet of inner nozzle 7 directly is communicated with inlet channel 16 on the base 6.
Described spring spacer 3 is fixed on the intermediate plate 9, and intermediate plate 9 is installed on the epithelium 5.
Described sealing ring 11 is installed on the skeleton 13, and skeleton 13 is fixedly mounted in the annular seal space 17.
The beneficial effect of the utility model:
1, the utility model can be saved the manual selector valve that existing nozzle institute must installation.Do not need artificial switching-over to make things convenient for operation, automatically according to admission pressure identification natural gas nozzle and liquefied gas nozzle.
2, save aluminum pipe and nut, reduced craft port, improved security.
3, the utility model can realize that a control valve and a plurality of drive nozzle combine to control the work of a plurality of burners.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is that the source of the gas of the utility model when working in low-pressure source of the gas (like natural gas) moves towards sketch map.
Fig. 3 is that the source of the gas of the utility model when working in high pressure source of the gas (like liquefied gas) moves towards sketch map.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Shown in Fig. 1-3.
The many gas source nozzles of a kind of pressure adaptive formula comprise base 6 and loam cake 2, and loam cake 2 is installed on the base 6 through rivet 4; Pressure spring 14 is installed in the loam cake 2, and an end and the adjusting nut 1 of pressure spring 14 offset, and the other end and spring spacer 3 offset; In the installing hole of the pressure spring 14 of adjusting nut 1 spinning on loam cake 2, spring spacer 3 is fixed on the intermediate plate 9, realizes the location of spring spacer 3 on epithelium 5 on the epithelium 5 thereby intermediate plate 9 is installed in; Be fitted between loam cake 5 and the base 6 around the epithelium 5; The main body of epithelium 5 is arranged in the epithelium chamber of being made up of loam cake 5 and base 6 15, and this epithelium chamber 15 is connected with inlet channel 16 on the base 6, and an end of seal bar 10 passes epithelium 15 and links to each other with spring spacer 3; The lower end of seal bar 10 is arranged in regulates chamber 17; The sealing ring 11 that can realize annular seal space 17 and epithelium chamber 15 on-offs that matches with seal bar 10 lower ends is installed in annular seal space 17, when specifically installing, can sealing ring 11 be installed in earlier on the skeleton 13; Skeleton 13 is fixedly mounted in the annular seal space 17; Described annular seal space 17 is connected through the inlet chamber of the outer nozzle 8 installed in the air flue on the base 6 18 and the nozzle installation cavity 19, in described outer nozzle 8, inner nozzle 7 is installed, and the air inlet of inner nozzle 7 directly is communicated with inlet channel 16 on the base 6.As shown in Figure 1, among Fig. 1,12 for being installed in the steel ball that in the fabrication hole fabrication hole is sealed.
