Abstract
The utility model discloses a dismounting-proof three-way valve for gas apparatus, comprising a shell, a gag and a dismounting-proof cover, wherein the gag is sealed in one of the passages of the three-way valve, on top of which a dismounting-proof cover is added. The upper end of the gag is a fan-shaped special start-stop key. The dismounting-proof cover is opened with a club lockhole. The structure of the dismounting-proof three-way valve for gas apparatus adopted by this utility model must use special tool to open, which may effectively prevent random or arbitrary dismounting and prevents occurrence of stealing gas because of random or arbitrary dismounting the three-way valve and gas leaking accidents.
Description
Technical field
The utility model relates to a kind of special-purpose tamper threeway of combustion gas that is used for gas pipeline.
Background technique
At present, three-port structure such as Fig. 4 of generally using of gas industry.Wherein, a channel interface in the threeway seals at Transverse plane by common gag.Three of this spline structure is connected with the defective of a maximum, is exactly that it can be by random dismounting, causes violating the regulationsly to steal gas and combustion gas is revealed, even can cause more serious consequence, as fire etc.The people life property safety is caused great hidden danger.
Summary of the invention
The purpose of this utility model provides a kind of can preventing arbitrarily or the caused special-purpose tamper threeway of combustion gas of stealing the generation of gas and combustion gas leakage accident violating the regulations of dismounting without authorization.
Task of the present utility model is finished like this: the special-purpose tamper threeway of a kind of combustion gas, comprise housing, gag and tamper lid, and its gag plug closes in one of them passage of threeway, adds a cover the tamper lid on it.The gag upper end portion is that the fan-shaped special use of a class opens and closes spoon.Tamper covers and has a plum blossom lockhole.
The special-purpose tamper threeway of combustion gas of the present utility model has twice tamper function, and the gag plug closes in three circulation passage, and the special use of its upper end portion opens and closes spoon and must just can open with special tool, and in addition, the plum blossom lockhole that tamper covers also must adopt special tool to open.Because the utility model is to design on the basis of former threeway, does not influence the pattern that connects with pipeline like this, and can effectively prevent arbitrarily or dismounting without authorization.
Description of drawings
Fig. 1 is a cut-away view of the present utility model.
Fig. 2 is a gag plan view of the present utility model.
Fig. 3 is a tamper lid plan view of the present utility model.
Fig. 4 is the sectional view of former threeway.
Among the figure, symbol 1 is represented three-way body, and symbol 2 is represented gag, and symbol 3 is represented the tamper lid, and symbol 4 is represented lead sealing, and symbol 5 is represented the special-purpose spoon that opens and closes.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in the figure, be a kind of sectional view of the present utility model, can be clearly seen that constituent element of the present utility model: the special-purpose tamper threeway of a kind of combustion gas comprises housing, gag and tamper lid, its gag plug closes in one of them passage of threeway, adds a cover the tamper lid on it.The gag upper end portion is that the fan-shaped special use of a class opens and closes spoon.Tamper covers and has a plum blossom lockhole.
Concrete installation steps are as follows: gag is made the threeway sealing with special tool by being threaded, again with tamper lid with special tool by the shutoff that is threaded at the Transverse plane place, water lead sealing then, with lathe lead sealing is scabbled, finally reach and prevent arbitrarily or the purpose of dismounting without authorization, solved the generation of stealing gas and combustion gas leakage accident violating the regulations that gas industry causes because of dismounting threeway arbitrarily or without authorization.
Claims (3)
