Abstract
The utility model relates to a device for testing air tightness of ship tanks. The device comprises storage tanks and an air compressor; the storage tanks are connected with the air compressor by a high pressure hose; the high pressure hose is provided with an air bag; each storage tank is provided with a pressure gauge; the storage tanks comprise a first storage tank and a second storage tank; the first storage tank is communicated with the second storage tank by an air guide pipeline; and a check valve is arranged on the air guide pipeline. The device is convenient to operate and simple in structure; the air tightness testing time of the two storage tanks can be shortened by 1/3 to 1/2, the working efficiency is improved, the construction period is shortened, and loss of air tightness testing equipment can be greatly reduced; and the device can be reused, so that the cost is reduced.
Description
Technical field
The utility model relates to a kind of device that is used for ship jar air-tight test.
Background technology
At present, the energy and chemical industry mainly rely on full voltage type LPG cargo ship with the transportation of liquefied gas, and the LPG cargo ship generally is made up of 2 or 2 above storage tanks, and volume is from 2500m
3To 6900m
3Not etc.Press the boats and ships related specifications, the ship jar belongs to the I grade pressure vessels, and construction must be carried out tightness test after accomplishing.Traditional tightness test method is that single storage tank carries out tightness test separately, adopts high-pressure hose that the pressurized air bag is connected with sweeping pipe on the storage tank air chamber, utilizes oilless air compressor that pressurized air is squeezed in the storage tank then, carries out air-tight test by code requirement.Equipment such as air compressor machine needed continuous working 7～15 days, and the test period is long and increased equipment loss virtually.
The utility model content
The utility model technical matters to be solved provides a kind of device that is used for ship jar air-tight test, and it can shorten for 1/3～1/2 duration, reduces equipment loss simultaneously.
A kind of device that is used for ship jar air-tight test; It comprises storage tank, air compressor machine, connects with high-pressure hose between storage tank and the air compressor machine, and high-pressure hose is provided with pressure dome; Storage tank is provided with tensimeter; It is characterized in that: described storage tank comprises first storage tank and second storage tank, uses the air guide pipeline connection between first storage tank and second storage tank, and the air guide pipeline is provided with stop valve.
The technique effect that the utility model is obtained:
1, the utility model is easy to operate, frock is simple, can two storage tank air-tight test times be shortened 1/3～1/2, has improved work efficiency, has shortened the duration, can reduce the loss of air-tight test equipment greatly, and this device can be reused, and has reduced cost.
Description of drawings
Fig. 1 is the vertical view of the utility model;
Fig. 2 is the front view of the utility model.
Embodiment
Further specify the embodiment of the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1-2, a kind of device that is used for ship jar air-tight test, it comprises storage tank, air compressor machine 1; Connect with high-pressure hose between storage tank and the air compressor machine; High-pressure hose 3 is provided with pressure dome 2, and storage tank is provided with tensimeter 6, and described storage tank comprises first storage tank 7 and second storage tank 8; Be communicated with air guide pipeline 5 between first storage tank and second storage tank, the air guide pipeline is provided with stop valve 4.
The utility model is to utilize hull and air guide pipeline as auxiliary mould, treat that the lifting of two storage tanks is gone on board after, carry out air-tight test again.With the air guide pipeline two storage tanks are coupled together, the centre is provided with a stop valve.Utilize air compressor machine that pressurized air is squeezed into first storage tank; Finish air-tight test by ship specification, qualified on inspection after, slowly open the stop valve in the middle of the air guide pipeline again; Utilize the pressure official post pressurized air of two storage tanks to import second tank body through pipeline; When the pressure of two storage tanks is consistent, close the stop valve in the air guide pipeline, stop air guide.At this moment, utilize air compressor machine to proceed to suppress again, reach the air-tight test requirement, by the standard end that makes an experiment up to pressure.This method can shorten for 1/3～1/2 duration, reduces the wearing and tearing that the plant equipment running has reduced equipment simultaneously.
The operating process of the utility model: treat two storage tanks all lift go on board after, and utilize pipeline that two storage tanks are connected as one, the centre is provided with stop valve.The sweeping pipe on air compressor machine 1, pressure dome 2 and high-pressure hose 3 and the air chamber is coupled together again, start air compressor machine 1 then and inflate to first storage tank 7, should close stop valve 4 this moment.Carry out the air-tight test of the left side first storage tank 7 earlier, adopt air compressor machine that pressurized air is squeezed into first storage tank 7, carry out air-tight test, finish until the air-tight test of first storage tank by code requirement.Stop valve 4 is slowly opened, the air in first storage tank 7 is imported the right second storage tank 8 through air guide pipeline 5, when the pressure of both sides tensimeter 6 demonstrations is consistent, close stop valve 4 (as shown in Figure 1).High-pressure hose 3 is connected (as shown in Figure 2) with the sweeping pipe of the right storage tank air chamber, utilizes oilless air compressor to suppress the air-tight test of carrying out second storage tank.
The protection domain of the utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and do not depart from the scope of the present invention and spirit the utility model.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, then the intention of the utility model also comprises these changes and is out of shape interior.
