Abstract
The utility model discloses a bogie pipeline pressure-maintaining testing device, which comprises a quick joint, a ball valve, a manual exhaust valve, a pressure gauge and hoses connected with the quick joint. The quick joint is sequentially and serially connected with the ball valve, the manual exhaust valve and the pressure gauge through steel pipes to form a pressure testing pipeline, the two hoses connected with the quick joint are connected in parallel to form a connecting pipeline, and the pressure testing pipeline is connected with the connecting pipeline in parallel. The bogie pipeline pressure-maintaining testing device is small in size, convenient to carry, conveniently connectable to a pipeline to be tested, simple in structure and low in failure rate.
Description
Technical field
The utility model relates to a kind of pressure test device, a kind of specifically bogie pipeline pressure-maintaining test device.
Background technology
Bogie air pressure test machine in original production also can be given the abundant pressurize of air spring because purposes is wider; Volume is big, and heavy, and the dirigibility portability is all undesirable, and equipment is prone to software fault; Need direct mounting gauge and blast pipe on brake piping during the pressurize test, it is cumbersome to operate, and manometric installation may need to destroy the integrality of the brake piping that has installed, and labour productivity is not high yet simultaneously, and labor strength is big.
The utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, proposes a kind of bogie pipeline pressure-maintaining test device, and it is little, easy to carry to have a volume; And can be connected to easily in the pipeline of required detection, simple in structure, the characteristics that failure rate is low.
In order to solve above technical matters, the utility model provides a kind of bogie pipeline pressure-maintaining test device, comprises rapid-acting coupling, ball valve, manual exhaust valve, tensimeter and is connected with the flexible pipe of rapid-acting coupling; Described rapid-acting coupling is followed in series to form the pressure measurement pipeline by steel pipe and described ball valve, manual exhaust valve and tensimeter, and is with two described flexible pipe formation in parallel connecting lines that are connected with rapid-acting coupling, again that described pressure measurement pipeline is in parallel with described connecting line.
The technical scheme that the utility model further limits is:
Aforesaid bogie pipeline pressure-maintaining test device in order to make the numerical value that records more accurate, is about 0.6MPa according to the force value of estimating, and selected manometric pressure measurement scope is 0～1MPa.
Further, this device use on bogie easily for convenience, aforesaid bogie pipeline pressure-maintaining test device, described hose length is 16～18m.
In order to be the good sealing effect of whole device, and can overhaul this device easily, aforesaid bogie pipeline pressure-maintaining test device, described connected mode be all for being threaded, and be wound with the sealing property that teflon guarantees pipeline on screw thread mouth.
The beneficial effects of the utility model are: the utility model is easy to be easy-to-use, both satisfies the needs of boosting productivity, and accuracy that again can warranty test has reached the purpose of saving cost simultaneously, meets the principle of lean production.This device mounting means is simply accurate, can shorten workman's built-up time greatly, alleviates labor strength, has obtained reaching satisfied effect after coming into operation.
Description of drawings
Fig. 1 is the utility model principle schematic.
Embodiment
A kind of bogie pipeline pressure-maintaining test device that present embodiment provides, structure comprise rapid-acting coupling 1, ball valve 2, manual exhaust valve 3, tensimeter 4 and are connected with the flexible pipe 5 of rapid-acting coupling as shown in Figure 1; Described rapid-acting coupling 1 is followed in series to form the pressure measurement pipeline by steel pipe and described ball valve 2, manual exhaust valve 3 and tensimeter 4, select the two approximately flexible pipe that has rapid-acting coupling 5 formation connecting lines in parallel of long 15 meters, again that described pressure measurement pipeline is in parallel with described connecting line.
Principle of work: pipeline pressurize test: connect air intake opening rapid-acting coupling, the bogie pipeline is connected with the rapid-acting coupling of flexible pipe, can begin test.Observe tensimeter, close ball valve after the pressure stability, the dwell time is as requested carried out pressurize, and the variation that can observe tensimeter numerical value in the pressure maintaining period determines whether to leak out and leakage rate.Carry out the pressurize test again after must filling exhaust three times earlier by operations platoon's air valve before the general pressurize.Close ball valve after test is finished, open vent valve, last detaching device.
Pipeline is revealed test: connect air intake opening rapid-acting coupling, the bogie pipeline is connected with the rapid-acting coupling of flexible pipe, can begin test.Observe tensimeter, must be earlier before the general leak detection fill exhaust three times by operations platoon's air valve after, inflate until tensimeter basicly stable once more.Be the leak case of available leak test fluid inspection pipe system this moment.Close ball valve after having checked, open vent valve, last detaching device.The purpose of this test mainly is to seek the leakage point of pipeline, and the effect of this device provides the quick access of pressure air.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
