Problems solved by technology

[0003] Therefore, it is necessary to test the performance of the air supply adjustment valve. However, the maintenance workshop of the depot does not have special equipment for the inspection of the air supply adjustment valve. Generally, the outsourced calibration method is used. The calibration cost of a single valve is about 500 yuan, which is relatively expensive. High, and the valve returned after calibration has been stored for a long time, and the performance of the air supply adjustment valve cannot be guaranteed before loading and use. Therefore, after loading and use, an on-vehicle test is required. Part of the performance of the valve is tested. If there are many performance problems with the air supply adjustment valve, frequent rework is required, and the replacement of the air supply adjustment valve is relatively difficult, which greatly affects the overall repair progress and quality. A test bench capable of performing performance tests on air supply control valves before use

Embodiment 1

[0037] refer to figure 1 , this embodiment discloses a micro-control air supply adjustment valve test bench, including a host system and a control system, the host system includes a cabinet 1, a test clamping device 2, and an air circuit system;

[0038] Cabinet 1 is a square integral structure, and its frame is welded by square tubes, which can ensure the quality well and is not easy to deform;

[0039] At the same time, the surface of the cabinet 1 is treated with plastic spraying, which is not only anti-corrosion, but also beautiful;

[0040] The inside of the cabinet 1 is equipped with a starting disk, a filter pressure reducing valve, an electromagnetic on-off valve, an electromagnetic reversing valve, a pressure sensor and other electrical components.

[0041] The cabinet 1 is also provided with operation buttons 11 , a touch screen 12 and a pressure gauge 13 .

[0042] refer to figure 2 and image 3 , the test clamping device 2 includes a base plate 21, a support 2...

Embodiment 2

[0089] refer to Figure 5 The difference between this embodiment and the first embodiment is that the test clamping device 2 is also provided with a positioning sleeve shaft 29 and a positioning sleeve 210; the positioning sleeve shaft 29 is fixedly installed on the bottom plate 21, and the positioning sleeve is located on the positioning plate 27 and the Between the seat 25; the positioning sleeve 210 is detachably installed on the positioning shaft sleeve.

[0090] The test clamping device 2 of this embodiment is used to clamp the threaded air supply adjustment valve. The bottom of the threaded air supply adjustment valve is cylindrical, and the bottom of the threaded air supply adjustment valve is placed in the positioning sleeve 210. And hold the threaded air supply adjustment valve and start the cylinder 23 at the same time, and clamp and fix the threaded air supply adjustment valve.

Abstract

The invention discloses a test bench for a micro-control air supply adjustment valve. The base plate is fixedly installed on the cabinet, the support is fixedly installed on the base plate, the cylinder is fixedly installed on the support, and the air outlet mold is fixedly installed on the piston rod of the cylinder. The air outlet mold is provided with a first air channel, and the air inlet of the first air channel is connected to the air system; the support seat is fixedly installed on the bottom plate, and the support seat is located in the direction of the piston rod of the cylinder, and the air inlet mold is fixedly installed on the support On the seat, there is a second air channel in the mold of the air inlet, and the air outlet of the second air channel is connected to the air system; the positioning plate is fixedly installed on the bottom plate and is located between the support and the support seat, and the positioning plate is provided for Place the positioning groove of the air supply adjustment valve; two positioning round pins are fixedly installed on the support seat, and are symmetrically arranged on both sides of the air inlet of the second air duct; the invention adopts an automatic control system, and the test process is carried out automatically; The problem of high strength improves the efficiency and quality of car repair.

Description

technical field [0001] The invention relates to the technical field of valve testing, in particular to a test bench for a micro-control air supply adjustment valve. Background technique [0002] The air supply adjustment valve is a safety component of the railway freight car, which is used in the pneumatic control device; when the positive air pressure of the air supply adjustment valve reaches a predetermined value, it will open in the positive direction to provide air for the control valve and brake air cylinder, etc. When the positive wind pressure is lower than the predetermined value, it will be closed in reverse to prevent the air pressure leakage of the control valve and the brake cylinder. [0003] Therefore, it is necessary to test the performance of the air supply adjustment valve. However, the maintenance workshop of the depot does not have special equipment for the inspection of the air supply adjustment valve. Generally, the outsourced calibration method is used...
