Abstract
The invention discloses a tightness test cover, is applicable to the technical field of tightness test covers, and aims to provide the tightness test cover which is simple in structure, convenient to use and high in safety performance. The tightness test cover comprises a cover body (1), wherein the cover body (1) is provided with a cover opening (2), a sealing strip (3) is arranged at the edge of the cover opening (2), and a magnet (4) or an electromagnet is arranged in the sealing strip (3). When the cover body (1) covers a cabin opening, at least one magnetic pole of the magnet (4) or the electromagnet faces a contact surface between the sealing strip (3) and the cabin opening, the edge of the cover opening (2) and the edge of the cabin opening are kept sealed, and the cover body (1) and a cabin form an airtight space. An air inlet pipe (6) communicated with the airtight space is further arranged on the cover body (1).
Description
Technical field
The present invention relates to a kind of tightness test cover.
Background technology
In the manufacture process of boats and ships, often need the cabins such as forepeak, afterpeak, fresh-water tank or bin to carry out tightness test, guarantee that the cabins such as forepeak, afterpeak, fresh-water tank and bin have good watertightness and impermeability.When tightness test is carried out in cabin, general method of operating is: on hatchcover, weld shutoff, then setting pressure meter connector and air intake opening, in pressure tapping, be connected with tensimeter, then by air intake opening, detection is inflated in cabin.After tightness test completes, also need to carry out the loaded down with trivial details operations such as perforate, test period is long, operate very inconvenient, test in also there will be cabin internal pressure excessive, cause cabin or bin to deform, in addition, if now have personnel in cabin in construction, its personnel are sealed in cabin by mistake, and this will threaten the life security of cabin indoor occupant.
Summary of the invention
Technical matters to be solved by this invention is to overcome the deficiencies in the prior art, provides a kind of performance simple in structure, easy to use, safe high tightness test cover.
The technical solution adopted in the present invention is: the present invention includes cover body, described cover body is provided with cover mouthful, a described cover mouthful edge is provided with sealing strip, in described sealing strip, be provided with magnet or electromagnet, when described cover body covers on cabin mouth, at least one magnetic pole of described magnet or described electromagnet is towards the surface of contact of described sealing strip and cabin mouth, the edge of described cover mouthful edge and described cabin mouth keeps sealing, described cover body and cabin form confined space, are also provided with the draft tube being connected with described confined space on described cover body.
On described cover body, be also provided with the tensimeter being connected with described confined space.
Described sealing strip lower end is provided with several grooves.
Described cover body is made by transparent organic glass.
The invention has the beneficial effects as follows: the design that has adopted Magnetic Phase to inhale due to the present invention, the present invention includes cover body, described cover body is provided with cover mouthful, a described cover mouthful edge is provided with sealing strip, in described sealing strip, be provided with magnet or electromagnet, when described cover body covers on cabin mouth, at least one magnetic pole of described magnet or described electromagnet is towards the surface of contact of described sealing strip and cabin mouth, the edge of described cover mouthful edge and described cabin mouth keeps sealing, described cover body and cabin form confined space, on described cover body, be also provided with the draft tube being connected with described confined space, when the gas of described confined space reaches certain pressure, described magnet or described electromagnet can not normal sorption steel plates, meeting automatic leakage air, thereby cabin can not be out of shape because pressure is excessive, effectively guarantee construction safety, so, the present invention is simple in structure, easy to use, also there is higher security, guarantee can not damage tested cabin, in airtight cabin, also have personnel when construction, workmen, as long as firmly can open described tightness test cover, can effectively guarantee workmen's life security.

Embodiment
embodiment mono-:
As shown in Figures 1 to 4, the present invention includes cover body 1, described cover body 1 is provided with cover mouth 2, described cover mouthful 2 edges are provided with sealing strip 3, in described sealing strip 3, are provided with magnet 4, and a magnetic pole of described magnet 4 is the surface of contact with cabin mouth towards described sealing strip 3, the magnetic force of described magnet 4 is determined according to the test pressure of the size of described tightness test cover and requirement, in the present embodiment, the magnetic force of described magnet 4 is made as the gravity of suitable 3kg object, and the ultimate value of test pressure is made as 0.03Mpa.When described cover body 1 covers on cabin mouth, the edge of described cover mouthful 2 edges and described cabin mouth keeps sealing, the edge of cabin mouth must be the material that energy Magnetic Phase is inhaled, in the present embodiment, the edge of described cabin mouth is steel plate, described cover body 1 forms confined space 5 with cabin, is also provided with the draft tube 6 being connected with described confined space 5 on described cover body 1.During test, by described draft tube 6 to the interior inflation of described confined space 5, when the gas of described confined space 5 reaches 0.03Mpa, described magnet 4 can not normal sorption steel plate, meeting automatic leakage air, thus cabin can not be out of shape because pressure is excessive, effectively guarantees construction safety; In addition, also have personnel in airtight cabin when construction, workmen, as long as firmly can open described tightness test cover, can effectively guarantee workmen's life security, compares with welding shutoff in the past, and the present invention has improved security performance greatly.
On described cover body 1, be also provided with the tensimeter 7 being connected with described confined space 5, by described tensimeter 7, can understand in real time the air pressure in described confined space 5.
Described sealing strip 3 lower ends are provided with several grooves 8, and in the present embodiment, described sealing strip 3 lower ends are provided with two described grooves 8.
In the present embodiment, described cover body 1 is made by transparent organic glass, by transparent organic glass, can be clear that the situation in described cover body 1, guarantees construction safety.
embodiment bis-:
In the present embodiment, be with the difference of embodiment mono-, in described sealing strip 3, be provided with electromagnet, by changing the adjusting that can realize easily suction by the electric current of described electromagnet, thereby can regulate easily the ultimate value of test pressure, guarantee that cabin or bin are can pressure not excessive and be out of shape, guaranteed construction safety.
The present invention is applied to the technical field of tightness test cover.
Although embodiments of the invention are described with practical solution, do not form the restriction to implication of the present invention, for those skilled in the art, according to this instructions to the modification of its embodiment and with the combination of other schemes be all apparent.
