Description

Technical Field

[0001] The utility model relates to the technical field of valve body testing, in particular to a surge valve testing tooling. Background Art

[0002] The surge phenomenon usually occurs when the compressor operates at low or high flow rates, which can lead to unstable air flow and then cause periodic vibration. This not only reduces the efficiency of the compressor, but may also cause serious damage to the mechanical structure. The surge valve can keep the operating point of the compressor away from the surge area by adjusting the flow rate or pressure, effectively avoiding the surge phenomenon and protecting the compressor from damage. It is a key component to ensure the stable operation of the centrifugal gas compressor.

[0003] In the intake system of a large-displacement natural gas engine, the role of the surge valve is particularly crucial. Specifically, when the engine suddenly unloads, the air pressures at both ends of the turbine are unbalanced, forming a turbulent flow, which impacts the turbine and the supercharger. At this time, the surge valve controls the air pressure within the surge range to balance the air pressures at both ends and protect the engine.

[0004] Due to the special structure of the surge valve, the process of its ex-factory performance testing is rather cumbersome. Before testing, the test cover plates need to be respectively installed on the intake port and the outlet port and tightened with screws. A plastic pad needs to be added at the front end of the screw to prevent scratching of the installation end face. The interfaces connected to the air pipes need to be blocked to ensure the accuracy of the test results, and the intake port opening pressure test and the outlet port leakage test need to be carried out respectively. The overall process requires a long test time and it is difficult to improve the efficiency of the test work.

[0005] The information disclosed in this background art section is only intended to deepen the understanding of the overall background art of the utility model, and should not be regarded as an admission or any form of implication that this information constitutes the prior art known to those skilled in the art.

[0037] A clamping assembly 30, arranged opposite to the ventilation block 21, for limiting the position of the valve body 01 to be tested, including a clamping block 31, a plug 32, a cylinder 33 and a three-axis cylinder 34.

The design of the profiling surface 31a enables the clamping block 31 to fit more precisely with the outer side surface of the valve body 01 to be tested, thus ensuring the stability and positioning accuracy of the valve body during the test; it also reduces the friction between the valve body and the clamping block 31, helping to reduce the wear of the valve body and the fixture during the test. In addition, the clamping block 31 with a suitable profiling surface 31a can be selected according to the specific shape of the valve body 01 to be tested, so that the test fixture can adapt to anti-surge valves of different sizes and shapes, increasing the versatility and flexibility of the fixture.

[0041] On the basis of the above embodiment, sealing grooves are provided on the sides of the test bottom plate 10 and the ventilation block 21 facing the valve body 01 to be tested, and the first sealing ring 11 and the second sealing ring 22 are respectively embedded in the sealing grooves of the test bottom plate 10 and the ventilation block 21. The design of the sealing grooves ensures that the sealing rings can be evenly stressed, reducing the possibility of the sealing rings shifting due to pressure changes, providing a better sealing effect, preventing gas leakage during the test, and thus improving the stability of the entire test fixture.

One end of the plug 32 facing the valve body 01 to be tested is hollow, and the sealing ring is placed inside the plug 32. Since a cylindrical convex sealing surface is formed at the hose connection of the valve body 01 to be tested, by providing the third sealing ring 35 in the plug 32, the sealing performance between the hose connection port 01c of the valve body 01 to be tested and the plug 32 can be ensured on the premise of protecting the sealing surface, preventing gas leakage. The built-in setting form also facilitates the inspection and replacement of the third sealing ring 35.

[0048] Based on the above embodiments, three-way interfaces 55 are arranged on both the first connecting air pipe 53 and the second connecting air pipe 54. Both the first connecting air pipe 53 and the second connecting air pipe 54 include a section of main pipe 54a and two sections of branch pipes 54b. The main pipe 54a connects the three-way interface 55 and the manual reversing valve 51. The branch pipe 54b of the first connecting air pipe 53 connects the three-way interface 55 and the speed control valve 52. The branch pipe 54b of the second connecting air pipe 54 connects the three-way interface 55 and the air cylinder 33 or the three-axis cylinder 34; the design of the three-way interface 55, the main pipe 54a, and the branch pipe 54b allows multiple branches to be separated from a single air source, providing flexible air circuit layout options to adapt to different control requirements, and also simplifies maintenance work, enabling quick disassembly and replacement, and facilitating inspection and repair.

[0049] When using the surge valve test tooling for testing, first place the surge valve to be tested on the test base plate 10, so that the assembly hole 01d on the side of the valve body air outlet 01b is sleeved on the positioning pin 41 for positioning. Move the entire valve body until the side of the air outlet 01b of the valve body 01 to be tested that is away from the positioning pin 41 abuts against the first limiting portion 42a provided on the limiting plate 42, and the outer side surface of the valve body 01 to be tested abuts against the second limiting portion 42b provided on the limiting plate 42. At this time, control the manual reversing valve 51 to supply air and adjust the speed control valve 52 to control the three-axis cylinder 34 and the cylinder 33 respectively, so that the piston of the three-axis cylinder 34 is pushed out, driving the clamping block 31 to move towards the surge valve to be tested, and the outer side surface of the valve body 01 to be tested is closely attached to the profiling surface 31a of the clamping block 31. The piston of the cylinder 33 is pushed out, driving the plug 32 to move towards the hose connection port 01c of the surge valve to be tested and forming a blocking effect, completing the assembly process of the surge valve to be tested.

After the test bench starts the test work, observe the action performance and sealing performance of the surge valve. When the test work is completed, control the piston rods of the three-axis cylinder 34 and the cylinder 33 to retract through the manual reversing valve 51, driving the clamping block 31 and the plug 32 to release the clamping effect on the surge valve. At this time, the surge valve can be removed, and the next surge valve to be tested can be replaced to repeat the above test process.
