Abstract

The invention relates to an exhaust valve performance test system and a test method. The test system comprises a compressor, a gas storage section pipeline, a flow measurement section pipeline and a test container, wherein the compressor, the gas storage section pipeline, the flow measurement section pipeline and the test container are successively connected in the gas flow direction. A first total valve is arranged between the compressor and the gas storage section pipeline. A number of parallel gas storage tanks are connected with the gas storage section pipeline. A first switching valve is arranged between the gas storage tanks and the gas storage section pipeline. The flow measurement section pipeline comprises a number of branch pipelines with different calibers, wherein the branch pipelines are arranged in parallel. A second switching valve is arranged in the inlet of each branch pipeline. A third switching valve is arranged in the outlet of each branch pipeline. Each branch pipeline is provided with a pressure regulating valve and a flowmeter. The test container is connected with a mounting pipe used for mounting a tested valve. A first pressure sensor is arranged in the inlet of the tested valve. The exhaust valve performance test system provided by the invention is extensible, and can support subsequent tests of larger exhaust valves by increasing the number of gas storage tanks or the number of branch pipelines.

Description

technical field [0001] The invention belongs to the field of exhaust valves, and in particular relates to an exhaust valve performance testing system and a testing method. Background technique [0002] The exhaust valve is usually installed at the highest point of the water supply pipeline to discharge the gas precipitated in the water in the pipeline to avoid head loss caused by gas accumulation in the pipeline. The exhaust valve is a key component to ensure smooth exhaust and safe operation of the water supply pipeline. The flowmeter in the existing exhaust valve performance testing device has a single measuring range, and can only be tested for exhaust valves with specific caliber specifications. Therefore, those skilled in the art urgently need to provide a system that is scalable and capable of performing performance tests on exhaust valves of various calibers. Contents of the invention [0003] In order to solve the above technical problems, the present invention pr...
