Further, on the said inlet end pipeline suction valve is installed.
The economical gas anti-explosion safety device of the utility model is connected with gas cylinder with the air outlet through suction port; Pipeline has certain anti-pressure ability; Shi Buhui bursts easily blasting; Even the gas valve of gas cylinder is blown up, also can realize the inlet end pipeline is closed automatically, and then prevent further to leak or blast.
The utility model compact structure, Safety performance is high, low cost of manufacture, energy consumption is low, and is applied widely.
Description of drawings
Fig. 1 is the utility model one embodiment's a structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
With reference to Fig. 1, present embodiment comprises piston 5, and piston 5 one ends link to each other with elastic support member 4 one ends; Elastic support member 4 is a spring, and elastic support member 4 the other ends are fixed on the inlet end pipeline 13 through support plate 3, and inlet end pipeline 13 1 end openings are suction port 1; Pipeline 14 1 end openings in outlet side are air outlet 8; Piston 5 places in the piston chamber 12, and piston chamber's 12 diameters are bigger than inlet end pipeline 13 and outlet side pipeline 14, between inlet end pipeline 13 and outlet side pipeline 14, are provided with a collapsible flexible Sealing 7; Sealing 7 is a plastic seal; Sealing 7 is built-in with plunger 72, and plunger 72 upper ends are disc 71, can drive collapsible flexible Sealing 7 and move together; The lower end of plunger 72 is a hemisphere 721, and the inlet end pipeline place under the plunger 72 is provided with the hemispherical groove 11 that the hemisphere lower end 721 with plunger 72 adapts, and is beneficial to realize the sealing to gas.
Said piston chamber 12 is the ball chamber; Piston 5 is a cylindrical piston; Inlet end pipeline 13 is a cylindrical pipe with outlet side pipeline 14, and the equal diameters of the diameter of piston 5 and inlet end pipeline 13 and outlet side pipeline 14 can play better seal action when being beneficial to work.
Said plunger 72 is a cylindrical bar scapus plug.
Working principle:
When combustion gas is blasted when gas valve blown up; Pressure in the outlet side pipeline 14 increases, and collapsible Sealing 7 upper ends stretch, the lower end compression; Thereby make plunger 72 hemisphere lower ends 721 go deep into closely cooperating with hemispherical groove 11 in the inlet end pipeline 13, inlet end pipeline 13 is blocked.Simultaneously, the effect that places the piston 5 in the piston chamber 12 to be under pressure, with length of spring compressed, piston 5 moves down, and inlet end pipeline 13 is blocked, and has constituted the double seal to inlet end pipeline 13 with plunger 72, thereby has prevented the further leakage and the blast of combustion gas.
When pipeline 14 internal pressures in outlet side were too high, insulation blocking sheet 6 was blown, and has prevented that manifold pressure is too high, has protected the safety of gas cylinder.
When insulation blocking sheet 6 is blown or after outlet side pipeline 14 bursts; Pressure-less state appears suddenly in outlet side pipeline 14 places; This moment, piston chamber's 12 interior pistons 5 bore the pressure from inlet end pipeline 13, made and moved stretching on the spring, and piston 5 moves under the effect of spring; Outlet side pipeline 14 is blocked, avoided the gas leakage in the gas cylinder.
