Description
Technical Field
The utility model belongs to the technical field of shipbuilding and specifically relates to a cabin gas tightness detection device.
Background
With the development of the ship industry, the requirement on the tightness of the cabin is higher and higher. For an open cell, water-filling tests are required to test the cell to ensure that the air-tightness of the weld at the cell boundary and the structural strength of the cell meet industry standards.
The special air tightness detection equipment has high manufacturing cost, high input cost for small-scale shipyards, large occupied area, heavy transportation and inconvenient carrying.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a simple structure, experimental effectual creates storehouse gas tightness detection device.
The utility model adopts the following technical scheme:
the utility model provides a cabin gas tightness detection device, includes the liquid level pipe, and the liquid level pipe is connected through the permeability cell of flange one with the cabin, is provided with the water injection pipe on the liquid level pipe.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model has the advantages of simple structure, easy to assemble, portable, it is with low costs moreover, the operating personnel direct observation experimental result of being convenient for.
Further, the utility model discloses a preferred scheme is:
the axis of the liquid level pipe and the axis of the water injection pipe form an included angle of 35-40 degrees.
And a connecting sleeve is arranged in the center of the flange I and is in threaded connection with the liquid level pipe.
The distance between the top end of the liquid level pipe and the upper surface of the cabin top plate is 1.5-1.7 m.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a diagram illustrating the operation of the present invention;
in the figure: a first flange 1; a connecting sleeve 2; a liquid level pipe 3; a water injection pipe 4; a second flange 5; a connecting bolt 6; a cabin 7; air outlet a 8; air outlet b 9; and a third flange 10.
Detailed Description
The invention is further described with reference to the following figures and specific embodiments.
The utility model provides a cabin gas tightness detection device, includes liquid level pipe 3, and liquid level pipe 3 is the straight tube, and the lower extreme of liquid level pipe 3 is provided with external screwed joint, and the lower extreme of liquid level pipe 3 is provided with flange 1, and welding has a connecting sleeve 2 in the centre bore of flange 1, and the upper end of connecting sleeve 2 is provided with the internal thread structure, and connecting sleeve 2 forms a whole with 3 threaded connection of liquid level pipe.
Be provided with a water injection pipe 4 on the lateral wall of liquid level pipe 3, the lower extreme of water injection pipe 4 is inserted in the water filling port of liquid level pipe 3 and is welded with liquid level pipe 3, and the axis of water injection pipe 4 is 35 with the axis contained angle of liquid level pipe 3.
In the application of the embodiment, the liquid level pipe 3 is in threaded connection with the first flange 1, then the first flange 1 is fixedly connected with the second flange 5 of the air outlet a8 of the cabin 7 through the connecting bolt 6, then the water injection pipe 4 is externally connected with a fire hydrant, water is injected into the cabin 7 until an air outlet b9 in the cabin 7 overflows outwards, it is proved that the cabin 7 is filled with water, and then the overflowed air outlet b9 is tightly sealed and covered through a third flange 10 (the third flange 10 is a blind flange); and continuously injecting water into the cabin 7, adjusting the water yield of the fire hydrant when the top of the liquid level pipe 3 begins to overflow outwards, keeping the liquid level of the liquid level pipe 3 at the highest point, and slowly overflowing, and then checking the water leakage condition from the next door cabin of the cabin 7 along the welding line.
Two air outlets are usually arranged on the same cabin 7, if the two air outlets of the cabin 7 are not at the same height, the device is arranged at the air outlet at the lower position, the air outlet at the higher position is used as the air-permeable end, and when the air outlet at the higher position overflows outwards, the situation that the water in the cabin is filled is proved. Then the air outlet at the higher end is sealed and covered tightly.
The utility model utilizes the pressure difference principle to detect the air tightness and the structural strength of the cabin 7, thereby being convenient for observing the liquid level change; moreover, the device is convenient to disassemble and assemble, convenient to carry and capable of being repeatedly used. Constructors use the device to detect the air tightness of the cabin 7, so that the detection efficiency is improved, and the equipment cost is reduced. The device can be used for detecting the air tightness and the structural strength of the cabin 7 and detecting container equipment such as a cabin cabinet, a pressure container cabinet and the like.
The above is only the concrete implementation manner of the present invention, but the protection of the present invention is not limited to this, and all the equivalent replacements or changes proposed to the technical features of the present technical solution that can be thought by those skilled in the art are included in the protection scope of the present invention.
