Problems solved by technology
[0002] It is an essential task to test the sealing, pressure or performance of the valve during the manufacturing process or before leaving the factory. The existing intelligent valve detection test bench usually adopts a liquid inlet high and low pressure switching method to pressurize, and the boosting speed Fast, during the boosting process, the fluid has an impact, which makes the detected pressure inside the valve fluctuate. Especially when the pressure is close to the target value, the boosting speed is fast, and the liquid impact makes the pressure display value unstable, causing the detection low precision

The invention discloses an intelligent synchronous boost relief valve experimental device including a base, a left arch, a middle arch, and a pressure supply system, and further including a pulsation eliminator, the pulsation eliminator eliminates the pressure pulsation caused by the low pressure switching to the high pressure when the two ends of a valve are synchronously subjected to boosting water supply, and the pulsation eliminator includes a casing, a balance device, a plurality of synchronizers, and a limiting device, a pair of liquid outlets in the casing are connected with the water inlet pipes at the two ends of the valve, the balance device is pivoted into the casing, the synchronizers are movably arranged on the lower circular wall in the casing, and the limiting device is arranged in the circular cavity and abuts between the synchronizers and the inner wall of the circular cavity. By means of the pulsation eliminator, the experimental device has the advantages of small impact, stable pressure rise when being close to the target pressure, and high detection precision.
Description
technical field [0001] The invention relates to the technical field of valve testing, in particular to an experimental device for intelligent synchronous increasing and draining valves. Background technique [0002] It is an essential task to test the sealing, pressure or performance of the valve during the manufacturing process or before leaving the factory. The existing intelligent valve detection test bench usually adopts the way of switching between high and low pressure at the liquid inlet to suppress the pressure. Fast, during the boosting process, the fluid has an impact, which makes the detected pressure inside the valve fluctuate. Especially when the pressure is close to the target value, the boosting speed is fast, and the liquid impact makes the pressure display value unstable, causing the detection Low precision. [0003] Therefore, there is an urgent need for an intelligent synchronous increase and release valve experimental device with small impact, stable boo...
