Abstract

The invention discloses a universal valve performance test device which comprises a test stand. A tee is arranged at the front end of the test stand, two branch pipes of the tee are respectively connected with an air pressure stabilizing system and a liquid flow stabilizing system, a computer control system is arranged on a side of the test stand, and the air pressure stabilizing system and the liquid flow stabilizing system can run under the control of the computer control system; the air pressure stabilizing system comprises an air compressor, the liquid flow stabilizing system comprises a water pump, the test stand comprises a to-be-tested valve, and a third branch pipe of the tee is connected with an inlet end of the to-be-tested valve; the computer control system comprises a computer, and the computer is in control connection with a first pressure sensor, a first flow sensor, a second pressure sensor, a liquid level sensor, a second flow sensor, a third pressure sensor, a temperature sensor and a fourth pressure sensor by a data collector. The universal valve performance test device has the advantages that low-pressure seal tests, high-pressure seal tests and flow characteristic tests can be carried out on the valve, and flow characteristic tests can be carried out on air-liquid double-phase flow valves.

Description

technical field [0001] The invention relates to a universal valve performance test device. Background technique [0002] Industrial valves, such as globe valves, ball valves, gate valves, butterfly valves, etc., must work normally under a certain pressure and flow. The quality of its performance directly affects the operation of the upstream, downstream and even the entire pipeline network of the valve during the production process. In actual production, the sealing ability of the valve is an important symbol to measure whether it is usable and durable. Through the valve test, check whether the leakage rate is within the allowable range, so as to judge whether the valve seal is qualified. The flow rate and flow resistance of the valve are the medium flow rate of the valve at different openings and the pressure loss of the medium after passing through the valve. For the valve used as a cut-off device, various factors affecting the flow resistance coefficient of the valve c...
