Abstract
The utility model belongs to the technical field of pipelines, and provides a blowing test device of locomotive pipelines. The blowing test device of locomotive pipelines is provided with a volume chamber (1) for storing wind quantity, a wind inlet pipe valve (2) for controlling wind supply of the volume chamber (1) is arranged on the volume chamber (1), a plurality of connecting pipes (7) for blowing the locomotive pipelines are arranged on the volume chamber (1), valves (4) matched with the diameter of the connecting pipes and used for controlling wind inlet and outlet quantity are respectively arranged on corresponding connecting pipes (7), and a pressure gage (3) for detecting pressure in the volume chamber is arranged on the volume chamber (1). The blowing test device of locomotive pipelines solves the problem of difficult blowing in the prior art, adopts the structural design, improves blowing efficiency, achieves clean wind utilization of the valves of a braking system, can not only perform high-pressure blowing on the pipelines in a blowing process, but also can display wind passing pressure of the pipelines. The locomotive pipelines are blocked to perform leakage finding tests.
Description
Technical field
The utility model belongs to the pipeline technical field, relates generally to a kind of lancing test experiment device of locomotive pipeline.
Background technology
At present; The purging apparatus of locomotive pipeline is exactly common sebific duct; Directly locomotive pipeline mouth of pipe hand is purged with the sebific duct port during purging, purge inserting for cover than the pipeline of minor diameter, the pipeline of big caliber purges for inserting; This blowing method not only leaks out, return air, pressure is low, energy waste is big, and purges poor effect.Above-mentioned in addition blowing method is often not quite clear with wind pressure to the purging of pipeline, can't judge the length and purging number of times of purge time.
Summary of the invention
For solving the problems of the technologies described above, the purpose of the utility model is the lancing test experiment device that proposes a kind of locomotive pipeline.
The utility model adopts following technical scheme for accomplishing the foregoing invention task:
A kind of lancing test experiment device of locomotive pipeline, described lancing test experiment device have in order to store the chamber volume of air quantity; On described chamber volume, has a blast pipe valve that is used to control the chamber volume air feed; Described chamber volume is provided with a plurality of tube connectors that the locomotive pipeline is purged; Corresponding described tube connector is provided with the valve that passes in and out air quantity with its diameter coupling, in order to control respectively; And the Pressure gauge in order to the detection volume room pressure is set on described chamber volume.
When purging, only open required valve and purge, check air-out port case (can carry out repeatable operation) until cleaning after, successively other each pipeline is purged the purpose that reaches in the pipeline clean.Airduct behind the purging adds stifled, can reveal, pressurize test.
The lancing test experiment device of a kind of locomotive pipeline that the utility model proposes has solved the problem that purges difficulty in the prior art, adopts the structural design of the utility model; Improved purging efficient, reached the clean of each valve of brakes, when purge with wind; Not only each pipeline can be purged by high pressure; The wind pressure of crossing that can also show this pipeline with the end sealing that purges back locomotive pipeline, can leak, the pressurize test.

Fig. 1 is the structural representation of the utility model.
Among the figure: 1, chamber volume, 2, the blast pipe valve, 3, Pressure gauge, 4, valve,
5, sebific duct, 6, hose coupling, 7, tube connector.
The specific embodiment
In conjunction with accompanying drawing and specific embodiment the utility model is explained:
As shown in Figure 1, a kind of blow device of locomotive pipeline, described lancing test experiment device have in order to store the chamber volume 1 of air quantity; On described chamber volume 1, has a blast pipe valve 2 that is used to control the chamber volume air feed; Described chamber volume 1 is provided with four tube connectors 7 that the locomotive pipeline is purged; Corresponding described four tube connectors 7 are provided with the valve 4 that passes in and out air quantity with its diameter coupling, in order to control respectively; Described valve 4 through sebific duct 5 and hose coupling 6, is connected with flexible pipe through hose coupling 6 respectively, and the locomotive pipeline is purged; Pressure gauge 3 in order to the detection volume room pressure is set on described chamber volume 1.
The utility model is opened blast pipe valve 2 in use, closes four valves 4 simultaneously; For chamber volume provides air intake, when the chamber volume internal pressure reaches 700 ~ 800KPa, open 4 pairs of flexible pipes of four valves 5 more respectively and purge with chamber volume 1; After the completion, the caliber of pressing tube connector connects sebific duct 5 and hose coupling 9, make blast be charged to 700 ~ 800KPa after; Open and need the scavenging pipeline corresponding valve that this pipeline on the locomotive is purged, 4 ~ 5 times repeatedly (the each purging needs single line to carry out), the pipeline of thick diameter as: blast main, train pipe will increase the purging number of times; By Pressure gauge detection volume chambers 31 internal pressure, make the chamber volume internal pressure remain on 700 ~ 800KPa when purging repeatedly, after purging finishes; Add stifledly at the end dress valve that is purged the locomotive pipeline, just can reveal test the locomotive pipeline.
When revealing test, when this test pipe fills wind to 800 ± 20KPa, close the tube valve 2 of the wind comes from, observe Pressure gauge 3, to be not more than 5KPa be qualified if per 5 minutes blast descend in the Pressure gauge 3, and pipeline is revealed test till qualified one by one.
