Abstract
The utility model discloses an air-tight test negative pressure cover which is used to detect tightness of a pipeline penetration structure. The air-tight test negative pressure cover comprises one arc-shaped glass cover which is provided with a negative pressure meter and at least one air valve. A concave arc-shaped side surface of the arc-shaped glass cover is matched with an external surface of a pipeline to be detected. The concave arc-shaped side surface is provided with at least one opening. A cavity is formed in the arc-shaped glass cover. The air-tight test negative pressure cover also comprises a sealing strip used for being contacted closely and tightly with the opening. The air-tight test negative pressure cover apparatus of the utility model is portable and has simple operation. By using the cover of the utility model, when a ship does not form a sealed cabin, a sealing state can be detected and sealing data can be provided.
Description
Technical field
The utility model relates to a kind of air-tightness detection device, particularly a kind of air-tight test negative pressure cover.
Background technology
In recent years, International Maritime Organization (IMO) (IMO) can constantly promulgate new mandatory standard, one of them be exactly boats and ships in building course, to the paint in ballast tank region, can only to carry out limited repairing be PSPC requirement, cause thus the close property of cabin to detect must to move forward to the segmentation fabrication phase that even the parts-moulding stage completes.Therefore, when boats and ships not yet form pressurized capsule, just can detect sealing state and sealing data are provided, becoming this area and be badly in need of the major issue solving.
Utility model content
The technical problems to be solved in the utility model is the defect that cannot shift to an earlier date signal piping sealing state while running through close property bulkhead in prior art in order to overcome, provide a kind of can detect easily and fast, exactly pipeline crossing cabin wall time the pipeline of sealing state run through the air-tight test negative pressure cover of structure.
The utility model solves above-mentioned technical matters by following technical proposals:
A kind of air-tight test negative pressure cover, the sealing that runs through structure for detection of pipeline, its feature is, described air-tight test negative pressure cover comprises that one is provided with the circular arc cloche of a vacuum table and at least one air valve, the indent arcuate flanks of described circular arc cloche is mated with the outside surface of pipeline to be detected, described indent arc side opening is provided with at least one opening, in described circular arc cloche, form a cavity, described air-tight test negative pressure cover also comprises a sealing strip for being closely adjacent to described opening.
Preferably, the radian of described circular arc cloche is 155 °～161 °.
Preferably, the material of described circular arc cloche is transparent organic glass.
Preferably, the thickness of described transparent organic glass is 7mm～9mm.The negative pressure that described transparent organic glass can bear is 0.015MP～0.025MP.
Preferably, the thickness of described circular arc cloche is 100mm～110mm.
Preferably, the quantity of described air valve is two.
Preferably, the width of described sealing strip is 20mm～22mm, and the thickness of described sealing strip is 25mm～30mm.
Wherein, the diameter of described circular arc cloche can regulate according to the diameter of pipeline concrete to be detected.
Meeting on the basis of this area general knowledge, above-mentioned each optimum condition, can combination in any, obtains each preferred embodiments of the utility model.
Positive progressive effect of the present utility model is: air-tight test negative pressure cover device of the present utility model is light, simple to operate, efficiently solve the problem that just can detect sealing state and sealing data are provided when boats and ships not yet form pressurized capsule, and the impermeability that this air-tight test negative pressure cover pipe of also going for other industry runs through structure detects.
Accompanying drawing explanation
Fig. 1 is the perspective view of air-tight test negative pressure cover of the present utility model.
Embodiment
Lift a preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
As shown in Figure 1, the air-tight test negative pressure cover of the present embodiment can run through for detection of pipeline the sealing of structure, it comprises that one is provided with a vacuum table 11, the circular arc cloche 1 of a gas admittance valve 12 and an air outlet valve 13, the radian of this circular arc cloche is 158 °, the thickness of this circular arc cloche is 105mm, it is the transparent organic glass of 7mm that this circular arc cloche is selected thickness, the indent arcuate flanks of described circular arc cloche is mated with the outside surface of pipeline to be detected, described indent arc side opening is provided with an opening, in described circular arc cloche, form a cavity, described air-tight test negative pressure cover also comprises a sealing strip 2 for being closely adjacent to described opening, the width of sealing bar is 20mm, thickness is 25mm.
Adopt the air-tight test negative pressure cover signal piping of the present embodiment as follows through the operating process of the sealing of bulkhead:
1) cleaning channels is through the weld seam of the required detection of bulkhead.
2) will show that masking liquid (industrial liquid detergent) spreads upon on the weld seam of needs test.
3) air-tight test negative pressure cover is covered on to the position while welding that needs test, and compress.
4) open gas admittance valve and observe vacuum table.
5) when vacuum table data reach requirement, close gas admittance valve and wait for quietly several minutes, guaranteeing vacuum table data stabilization.
6) see through whether bubble of demonstration masking liquid that transparent air-tight test negative pressure cover observes commissure.
7) if there is bubble, record emits bubble position, opens air outlet valve, detaching device, the leak source of correction weld seam.
Although more than described embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these changes and modification all fall into protection domain of the present utility model.
