Alternate one-way valve and pressurization system

Abstract

The invention discloses an alternate one-way valve and a pressurization system. The alternate one-way valve comprises a valve body and a valve core; a liquid inlet and a liquid return opening are respectively formed in two ends of the valve body; a working opening is formed in the middle part of the valve body; the valve core is arranged in the valve body; the front end of the valve core faces the liquid inlet; a spring is arranged between the rear end of the valve core and the liquid return opening; the pressurization system comprises a pressurizer, a choke plug and a liquid return tank; the alternate one-way valve is connected between the large cavity of the pressurizer and the choke plug; the liquid inlet of the alternate one-way valve is connected with the choke plug; the liquid return opening of the alternate one-way valve is connected with a liquid return pipeline; the working opening of the alternate one-way valve is connected with the large cavity of the pressurizer. The alternate one-way valve is applied to the pressurization system in a laboratory, so the pressure is stably increased, and the test efficiency is increased.

Description

technical field [0001] The invention relates to a hydraulic test system, in particular to an alternate check valve and booster system. Background technique [0002] At present, when performing high-pressure tests on the test piece in the test system, since there is no such high-pressure pump source, it is necessary to first fill the booster with the emulsion flowing out of the pump station and then pressurize the test piece. , so as to carry out the high pressure test. However, when the high-pressure emulsion output from the high-pressure chamber of the supercharger flows into the test piece, overpressure often occurs due to various reasons, which leads to the failure of this test. Adding a throttle plug to the booster pipeline can achieve stable growth pressure effect; however, the liquid filling time is lengthened, resulting in low test efficiency. Contents of the invention [0003] The object of the present invention is to provide an alternate check valve and a pressu...
