A kind of cabin tightness simple operation box

technical field

The utility model relates to the technical field of ship tooling equipment, in particular to a cabin airtight simple operation box.

Background technique

In the process of ship construction, when the structural integrity of a certain tank is submitted, its tightness needs to be tested to check the welding quality of the relevant welds of the tank. Prior Art Chinese Patent No. CN201220520635.0 cabin tightness test device, CN200920211423.2 a test device for ship cabin tightness test, these traditional methods are by assembling U-shaped tubes and injecting water, by observing the water column in the U-shaped tube Lifting and lowering to judge the tightness of the cabin, this method requires a series of relatively complicated preparations such as self-tightness inspection and U-shaped tube placement when it is implemented, which increases the difficulty of operation; when it is recycled, the pressure gauge Frequent disassembly and assembly of connecting pipe parts will cause unnecessary damage. Prior Art Chinese Patent No. CN200920211423.2 is a test device for the tightness test of ship cabins. It uses connecting pipes to be placed in a U-shaped structure and fixed with brackets. However, due to the complexity of the cabin manufacturing environment, it is often difficult for such scattered device poses great difficulties.

Contents of the invention

The purpose of the utility model is to provide a simple operation box with tightness of the cabin, which solves the above technical problems.

In order to achieve the above-mentioned technical purpose and meet the above-mentioned technical requirements, the technical solution adopted by the utility model is: a cabin airtight simple operation box, including an airtight box; an airtight cavity is formed inside the airtight box; the airtight The upper end surface of the box body is provided with a detection installation pipe, a pressure gauge installation pipe, an air intake installation pipe and a water injection installation pipe; the detection installation pipe, the pressure gauge installation pipe, the air intake installation pipe and the water injection installation pipe are all communicated with the airtight cavity; It is characterized in that: the detection installation pipe extends into the bottom of the sealed box; the detection installation pipe is connected with a transparent hose; the pressure gauge installation pipe is connected with a pressure gauge; the water injection installation pipe is connected with a cut-off valve.

Preferably: the length of the transparent hose is at least 2m.

Beneficial effects of the utility model: a cabin airtight simple operation box, compared with the traditional structure: the overall box structure design is convenient for placement in complex environments, and it is more convenient to operate; Various installation tubes are convenient for later maintenance and replacement, and can be recycled.

detailed description

In order to make the purpose of the invention, technical solutions and beneficial technical effects of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods;

In the accompanying drawings: a cabin airtight simple operation box, including an airtight box body 1; an airtight cavity 2 is formed inside the airtight box body 1; a detection installation pipe 3 and a pressure gauge are arranged on the upper end surface of the airtight box body 1 The installation pipe 4, the air intake installation pipe 5 and the water injection installation pipe 6; the detection installation pipe 3, the pressure gauge installation pipe 4, the air intake installation pipe 5 and the water injection installation pipe 6 are all communicated with the airtight cavity 2; the detection installation The pipe 3 extends into the bottom of the sealed box; the detection installation pipe 3 is connected with a transparent hose 301; the pressure gauge installation pipe 4 is connected with a pressure gauge 401; the water injection installation pipe 6 is connected with a shut-off valve 601 ;Through the box-type integrated design, various installation pipes required for detection are arranged on the sealed box body 1, and only the required devices for detection need to be installed on the corresponding installation pipes during installation, which is easy to operate and convenient for later maintenance and maintenance; The shut-off valve 601 can be closed after filling water, so as to ensure that the sealing performance of the operation box is good during detection.

The length of the transparent hose 301 is at least 2m; the arrangement of the transparent hose can visually and safely display the real-time pressure of the cabin, and can be put away after use, saving space; the length of the transparent hose 301 is at least 2m, 2m The high water column is converted into pressure, which can meet the 0.2 bar required for measuring pressure.

The specific implementation of the utility model: first arrange the installation pipe required for detection on the sealed box body 1, wherein the detection installation pipe 3 needs to extend into the bottom of the sealed box body 1; arrange a transparent hose 301 on the detection installation pipe 3, transparent The length of the hose 301 is at least 2m; connect the pressure gauge 401 to the pressure gauge installation pipe 4, the commonly used test pressure is 0.2bar, and a pressure gauge with a range of 1bar can be selected; connect the air pipe to the air intake installation pipe 5, and the other end of the air pipe Connect to the air outlet of the airtight cabin; install a shut-off valve 601 on the water injection installation pipe 6, and connect the other end of the shut-off valve 601 to a water pump; inject water into the airtight box 1 through the water pump, and when the water surface is 3-5cm away from the inside of the box, the It can stop, and close the shut-off valve 601 at the same time; then check the airtightness of the entire operation box to ensure that the gas is filled into the air inlet hole of the airtight cabin after passing, and stop when the water column in the transparent hose 301 reaches 2m, and close it at the same time The stop valve installed on the air inlet; finally observe whether the height of the water column changes, if there is no change, it proves that the sealing performance of the airtight cabin is good.
