The rear end of every above-mentioned pipeline is provided with safety valve: the outer end of every pipeline is that reaming forms large-diameter portion and minor diameter part, form valve seat between large-diameter portion and the minor diameter part, in large-diameter portion, be provided with piston, the front end of piston stretches in the minor diameter part and forms sealing with valve seat, the rear end of piston is formed with spring seat, adjusting nut is screwed onto the outer end of large-diameter portion, be bolted with adjusting screw rod at adjusting nut, the front end of adjusting screw rod is provided with spring seat, between the spring seat of the spring seat of adjusting screw rod and piston, be connected by Returnning spring elasticity, be provided with the front end of every pipeline of UNICOM and the vent of rear end at the sidewall of the head of piston.
Be connected with exhaust joint on the output pipeline of the outside delivery pressure that arranges on above-mentioned every stage pressure chamber.
Be provided with valve on the above-mentioned exhaust joint.
The advantage that the present invention gives prominence to compared to existing technology is:
1, the present invention is simple to operate, and once adjusting behind the pressure does not just need to regulate again;
2, the present invention adopts spring structure, can will be in the previous stage pressure chamber gas automatic shunt of over pressure in first class pressure chamber once, reduced energy waste, can also prevent the danger of the internal mold blast that superpressure causes;
3, the present invention is simple in structure, and good reliability will need several safety valves to be incorporated in the distributor, save a lot of adapters, make whole pipeline more succinct, save the space, and volume is little;
4, the pressure gauge of setting of the present invention can be monitored the pressure size in the distributor at any time, and is safe and reliable;
5, the present invention is applicable on the tire sulphureted jar.
Description of drawings:
Fig. 1 is generalized section of the present invention;
Fig. 2 is one of schematic perspective view of the present invention;
Fig. 3 is two of schematic perspective view of the present invention.
Embodiment:
The invention will be further described with specific embodiment for the below, referring to Fig. 1-3:
A kind of source of the gas automatic distributor with Safety function, in distributor body 10, be provided with the pressure chamber that two-stage is successively decreased successively with upward pressure, the pressure of previous stage pressure chamber branches in the rear first class pressure chamber, be provided with safety valve 180 between the adjacent two-stage pressure chamber, be provided with the output pipeline of outside delivery pressure in every stage pressure chamber, be linked with the input pipeline 30 that is connected with source of the gas in first class pressure chamber 20.
Be provided with the pressure gauge 40 of detected pressures cavity pressure size on above-mentioned every stage pressure chamber.
Pressure chamber more than the above-mentioned two-stage is formed by the pipeline of one or more, mutual UNICOM between every pipeline, every after the front end of pipeline all be connected to accordingly rear end at last pipeline, the equal passes therethrough body 10 in the rear end of every pipeline, the front end of first pipeline is first class pressure chamber 20, and be connected with the output pipeline 50 of source of the gas and outside delivery pressure respectively, the rear end of every one-level pipeline forms the next stage pressure chamber with the front end UNICOM of corresponding next bar pipeline, and the rear end of described every pipeline is provided with safety valve 180.
The rear end of every above-mentioned pipeline is provided with safety valve 180: the outer end of every pipeline is that reaming forms large-diameter portion and minor diameter part, form valve seat 60 between large-diameter portion and the minor diameter part, in large-diameter portion, be provided with piston 70, the front end of piston 70 stretches in the minor diameter part and forms sealing with valve seat 60, the rear end of piston 70 is formed with spring seat 80, adjusting nut 90 is screwed onto the outer end of large-diameter portion, on adjusting nut 90, be bolted with between two parties the adjusting screw rod 100 with adjusting nut 90 coaxial lines, the front end of adjusting screw rod 100 is provided with spring seat 110, between the spring seat 80 of the spring seat 110 of adjusting screw rod 100 and piston 70, be connected by Returnning spring 120 elasticity, sidewall at the head of piston 70 is provided with the front end of every pipeline of UNICOM and the vent 130 of rear end, when piston 70 seals with valve seat 60, pressure in the upper level pressure chamber is not shunted, when piston 70 separated with valve seat 60, the superpressure part in the upper level pressure chamber branched in next pressure chamber by the vent 130 on the piston 70.
