Abstract

The utility model discloses a prevent back pressure saddle -type, including electric smelting saddle type pipe fitting, be equipped with in the electric smelting saddle type pipe fitting and prevent the back pressure pipe, prevent being equipped with in the back pressure pipe and prevent the back pressure piece, prevent the back pressure piece and guarantee that the gas can not flow back and lead to gas conveying speed to become slow or spill over and various unsafe condition appear through setting up to be equipped with in preventing the back pressure pipe and preventing the back pressure pipe in electric smelting saddle type pipe fitting.

Description

Prevent back pressure saddle
Technical field
The utility model relates to pipeline connection area, is specifically related to prevent back pressure saddle.
Background technique
Electric smelting saddle type pipe fitting is the passage of fuel gas transmission, is mainly divided into three major types: straight-through saddle, bypass saddle, shutoff saddle; Straight-through saddle is applicable to as branch in the pipeline of main pipeline not with gas, laying not with pressure, new, substitutes threeway, needs special cutting tool, main pipeline is upon connection holed, then can use after connection; Bypass saddle is applicable in the pipeline of main pipeline band gas, subsidiary low pressure as branch, substitute threeway, incidentally there is in pipe fitting the combination cutting tool that can be cut supervisor's material wall, use combination cutting tool to cut after connecting and be responsible for material, after cutting completes, instrument restores, still staying in saddle pipe fitting, is the pipe fitting for constructing with gas; Shutoff saddle is then exclusively used in the special pipe fitting repairing scuffing and tiny gas leakage point on polyethylene pipe.
Electric smelting saddle type end cap is then electric smelting saddle type pipe fitting can be blocked the device preventing combustion gas from flowing out, but existing electric smelting saddle type end cap just adopts bolt tightening to be fixed on electric smelting saddle type pipe fitting by electric smelting saddle type end cap, easy generation loosens, and causes gas leakage; And the gas in electric smelting saddle type pipe fitting can reflux, electric smelting saddle type pipe fitting is caused to go wrong.
Model utility content
The purpose of this utility model be in order to provide can prevent combustion gas back pressure prevent back pressure saddle.
The utility model is achieved through the following technical solutions: prevent back pressure saddle, comprises electric smelting saddle type pipe fitting, is provided with anti-back pressure conduit in described electric smelting saddle type pipe fitting; Anti-back pressure part is provided with in described anti-back pressure conduit.
The utility model ensures that combustion gas can not reflux and causes fuel gas transmission to slow by arranging anti-back pressure conduit and be provided with anti-back pressure part in electric smelting saddle type pipe fitting in anti-back pressure conduit or overflow and occur various danger situation.
Usefulness of the present utility model is: 1) in electric smelting saddle type pipe fitting, be provided with anti-back pressure conduit, is provided with anti-back pressure part, prevents fuel gas return-flow in anti-back pressure conduit; 2) by electric smelting saddle type pipe fitting inner wall shave shape tooth and the supravasal shape tooth of shaving of anti-back pressure coordinates and cooperatively interacts, electric smelting saddle type pipe fitting and anti-back pressure conduit are fitted tightly, anti-sliding stop and cause gas leakage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
See Fig. 1, prevent back pressure saddle, comprise electric smelting saddle type pipe fitting 1, in described electric smelting saddle type pipe fitting 1, be provided with anti-back pressure conduit 8; Anti-back pressure part 9 is provided with in described anti-back pressure conduit 8.
In present embodiment, the shape tooth of shaving shaved on shape tooth and anti-back pressure conduit 8 on electric smelting saddle type pipe fitting 1 inwall cooperatively interacts, and makes electric smelting saddle type pipe fitting 1 and anti-back pressure conduit 8 more fit tightly by cooperatively interacting, anti-sliding stop and cause gas leakage.
In present embodiment, ensure that combustion gas can not reflux and cause fuel gas transmission to slow by arranging anti-back pressure conduit 8 and be provided with anti-back pressure part 9 in electric smelting saddle type pipe fitting 1 in anti-back pressure conduit or overflow and occur various danger situation; Ensure that the Security of fuel gas transmission, can the Development of Urban rock gas visual field better, utilize the energy scientifically and rationally, conservation of nature environment, air conservation also can meet social each field to the demand of rock gas.
Protection domain of the present utility model includes but not limited to above mode of execution; protection domain of the present utility model is as the criterion with claims, and any replacement that those skilled in the art will find apparent that, distortion, improvement made this technology all falls into protection domain of the present utility model.

Claims (2)
