But, combustion gas all has inflammable and explosive characteristic, no matter be that rock gas or biogas all have this characteristic, concerning fuel gas generation unit, be an important trouble free service therefore explosion-proof, the volume of the existing explosion-proof valve for fuel gas generation unit is all larger, installation and removal are inconvenient, and the gas pipeline diameter of fuel gas generation unit is required also stricter, serious restriction the development of fuel gas generation unit.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of gas machine explosion-proof valve, and this gas machine explosion-proof valve volume is small and exquisite, mounts and dismounts all more conveniently, and requires not tight, applied widely to the gas pipeline diameter of fuel gas generation unit.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of gas machine explosion-proof valve, comprises valve body, and one end of described valve body is provided with valve gap; Also comprise that one passes the screw mandrel of described valve body and described valve gap simultaneously, one end that described screw mandrel passes described valve gap is provided with nut, one end that described screw mandrel passes described valve body is provided with locating stud, on described screw mandrel between described locating stud and described valve body, be arranged with positioning block, on screw mandrel between described positioning block and described valve body, be arranged with elastic component, the two ends of described elastic component are separately fixed on described positioning block and described valve body.
Wherein, described valve body is provided with flange plate near one end of described valve gap.
Wherein, described flange plate and described valve body are structure as a whole.
Wherein, described positioning block is the nut matching with described screw mandrel.
Wherein, described elastic component is stage clip.
Adopted after technique scheme, the beneficial effects of the utility model are:
Because the utility model gas machine explosion-proof valve comprises valve body, one end of valve body is provided with valve gap; Also comprise that one passes the screw mandrel of valve body and valve gap simultaneously, one end that screw mandrel passes valve gap is provided with nut, one end that screw mandrel passes valve body is provided with locating stud, on screw mandrel between locating stud and valve body, be arranged with positioning block, on screw mandrel between positioning block and valve body, be arranged with elastic component, the two ends of elastic component are separately fixed on positioning block and valve body.In use, only a threeway need to be installed on the gas pipeline of gas machine, valve body is fixed in threeway, the end of screw mandrel is positioned at gas pipeline, in the time that the air pressure in gas pipeline raises, can drive valve gap to move up after screw mandrel is under pressure, compression elastic piece simultaneously, gas in the time that valve gap separates with valve body in gas pipeline can be discharged by valve body, and after the air pressure in gas pipeline reduces, elastic component can drive valve gap to reset.Visible the utility model volume is small and exquisite, simple in structure, and installation and removal are convenient, and the length of its screw mandrel can change according to the diameter of gas pipeline, makes its accommodation extensive.
In sum, it is large that the utility model gas machine explosion-proof valve has solved in prior art explosion-proof valve volume, loads and unloads inconvenient technical problem.The utility model gas machine explosion-proof valve volume is small and exquisite, and installation and removal are convenient, and requires not tight, applied widely to the caliber of gas pipeline.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model gas machine explosion-proof valve;
Wherein: 10, valve body, 20, valve gap, 30, screw mandrel, 32, locating stud, 40, elastic component, 50, nut, 60, flange plate, 70, positioning block.
Embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.
As shown in Figure 1, a kind of gas machine explosion-proof valve, comprises valve body 10, and one end of valve body 10 is provided with valve gap 20.Also comprise that one simultaneously through the screw mandrel 30 of valve body 10 and valve gap 20, one end that screw mandrel 30 passes valve gap 20 is provided with nut 50, and valve gap 20 is threaded with screw mandrel 30.One end that screw mandrel 30 passes valve body 10 is provided with locating stud 32, on the screw mandrel 30 between locating stud 32 and valve body 10, is arranged with positioning block 70, and positioning block 70 is the nut suitable with screw mandrel 30, and locating stud 32 is for giving positioning block 70 spacing.On screw mandrel 30 between positioning block 70 and valve body 10, be arranged with elastic component 40, the two ends of elastic component 40 are separately fixed on positioning block 70 and valve body 10, and elastic component 40 is stage clip.
As shown in Figure 1, valve body 10 is provided with flange plate 60 near one end of valve gap 20, and flange plate 60 is structure as a whole with valve body 10.Flange plate 60 is for being arranged on gas pipeline by valve body 10.
As shown in Figure 1, the length of screw mandrel 30 can be selected according to the diameter of gas pipeline.Can pass through to change stage clip gauge of wire size, and/or rotating nut 50 regulates the pressure size of opening explosion-proof valve.
As shown in Figure 1, working principle of the present utility model is as follows:
