Description
Technical Field
The invention relates to the field of shipbuilding, in particular to a cabin air tightness detection tool.
Background
At present, the cabin tightness is a project which must be submitted to inspection in the ship construction process, and is an important way for inspecting whether the welding seam of the ship has defects. For sealed cabins, such as oil cabins, water cabins and the like, only the manhole is sealed by a door cover, compressed air is injected into the sealed cabin, and after the specified pressure and the duration are reached, the test liquid is sprayed on the surface of the tested welding seam to check the penetration condition of the welding seam. After the detection is finished, the detection personnel generally judge the residual pressure in the closed cabin according to the display value of the pressure gauge, however, the indication of the pressure gauge is not visual, and the risk of display error exists.
Disclosure of Invention
The invention aims to provide a cabin air tightness detection tool which is visual in display and capable of eliminating potential safety hazards, aiming at the defects in the prior art.
In order to achieve the purpose, the cabin air tightness detection tool adopts the technical scheme that:
the utility model provides a cabin gas tightness detects frock, is provided with the sealing member including the apron that is used for the shutoff manhole between the back of apron and the manhole frame, the front of apron be provided with intake pipe and the monitoring pipe of manhole intercommunication, the mid-mounting of intake pipe has first control valve, the mid-mounting of monitoring pipe has the second control valve, the manometer is installed to the afterbody of monitoring pipe, the explosion-proof hole with the manhole intercommunication is seted up to the apron, and the positive one side of the orientation apron of explosion-proof hole is provided with the explosion-proof piece, and the explosion-proof piece is used for the shutoff through-hole. After the cover plate blocks the manhole, the cabin is inflated through the air inlet pipe, and the explosion-proof sheet bulges along with the increase of the pressure in the cabin; when the detection is finished, after the cabin is decompressed, the explosion-proof sheet is restored to the original state to show that no residual pressure exists in the cabin.
Preferably, the diameter of the explosion-proof air hole is 25-35mm, and the diameter of the explosion-proof sheet is 35-45 mm.
Preferably, the explosion-proof sheet is made of rubber.
Preferably, the thickness of the explosion-proof sheet is 1.5-2.5 mm.
