Abstract
The utility model discloses a novel dustproof cover of a fuel gas shut-off valve shape and relates to a fuel gas shut-off valve, in particular to an improved dustproof cover of the fuel gas shut-off valve shape. The dustproof cover comprises a dustproof cover body (1). A button hole (2) is formed in the upper portion of the dustproof cover body (1). A ring-shaped groove (3) and a clamping table (5) are sequentially arranged along the periphery of the outer surface of the lower end opening of the dustproof cover body (1) from bottom to top. The section of the clamping table (5) is trapezoidal. A ring-shaped seal ring (4) is installed in the groove (3). The section of the seal ring (4) is oval. The novel fuel gas shut-off valve shape dustproof cover solves the problems that an existing dustproof cover of a fuel gas shut-off valve is inconvenient to disassemble and assemble, poor in sealing property and the like.
Description
Technical field
The utility model relates to gas cut off valve, is specifically related to the improvement of gas cut off valve shape dust-proof cover.
Background technique
Gas alarm cut-off device is the safety installations for gas pipeline.It forms the gas emergency cut-off system together with fuel gas alarm.When gas leakage reaches finite concentration, as the linkage of alarm within 0.5 second time by fuel gas shutoff, thereby avoided blast and intoxication accident.
The problems such as the dust-proof cover of existing gas cut off valve is to be threaded with main casing, has the dismounting inconvenience, and sealing is poor.
Summary of the invention
The problems such as the utility model provides a kind of novel gas cut off valve shape dust-proof cover, and the dust-proof cover that the utility model has solved existing gas cut off valve is to be threaded with main casing, causes the dismounting inconvenience, and sealing is poor.
For addressing the above problem, the utility model adopts following technological scheme: a kind of novel gas cut off valve shape dust-proof cover, comprise a dust boot body 1, be provided with button hole 2 above dust boot body 1, be disposed with annular groove 3 and Ka Tai 5 from bottom to top along the periphery place at dust boot body 1 lower end mouth outer surface, the sectional shape of card platform 5 is trapezoidal, and annular seal ring 4 is installed in groove 3, and the cross section of seal ring 4 is oval.
Advantage of the present utility model: owing to having adopted card platform mode to connect dust-proof cover and main casing, easy disassembly; Owing to having adopted seal ring, strengthened sealability.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Symbol description in figure: dust-proof cover main body 1, button hole 2, groove 3, seal ring 4, card platform 5.
Embodiment
Below by best embodiment, the utility model is described in detail
.
As shown in Figure 1, a kind of novel gas cut off valve shape dust-proof cover, comprise a dust boot body 1, be provided with button hole 2 above dust boot body 1, be disposed with annular groove 3 and Ka Tai 5 from bottom to top along the periphery place at dust boot body 1 lower end mouth outer surface, the sectional shape of card platform 5 is trapezoidal, and annular seal ring 4 is installed in groove 3, and the cross section of seal ring 4 is oval.
Card platform 5 downsides and dust boot body lower end surface included angle A are the 21-27 degree.
Finally it should be noted that: obviously, above-described embodiment is only for the utility model example clearly is described, and is not the restriction to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all mode of executions.And the apparent variation of being amplified out thus or change are still among protection domain of the present utility model.
Claims (2)
