Embodiment Construction

[0014] The technical solution of the present invention is further described below in conjunction with the accompanying drawings, but the scope of protection is not limited to the description.

[0015] Such as figure 1 As shown, the liquid-controlled hydraulic balance valve of the present invention is mainly composed of a safety valve 1, a one-way valve 2, and a back pressure regulating valve 3. The present invention also relates to a test method for a liquid-controlled hydraulic balance valve, Firstly, the safety pressure value of the safety valve is obtained by adjusting and locking the safety valve, and then the forward flow resistance and reverse flow resistance of the single channel of the hydraulic balance valve are obtained through the single-channel flow resistance test (forward channel, reverse channel). Finally, the flow resistance of the entire balance valve is calculated by shorting the oil port.

Abstract

The invention discloses a hydraulic control type test method for a hydraulic balance valve. The hydraulic control type test method comprises the following steps of: at first, adjusting and locking a security pressure value of a safety valve; secondly, obtaining positive flow resistance and inverse flow resistance of a single path of the hydraulic balance valve through a single-path flow resistance test (a positive channel and an inverse channel); and finally, calculating flow resistance of the entire balance valve by means of shortly connecting an oil opening. With the adoption of the method provided by the invention, basic parameters (such as security valve pressure, single-path positive flow resistance, inverse flow resistance, and flow resistance of the entire valve) of the hydraulic control type test method for the hydraulic balance valve can be obtained, so as to provide certain important foundations for examination and acceptance inspection of the balance valve.

Description

technical field [0001] The invention belongs to the technical field of hydraulic transmission control, and in particular relates to a test method for a hydraulic control type hydraulic balance valve. The method of testing in inspection and delivery re-inspection greatly improves the consistency of product production and delivery. Background technique [0002] In the development of the hydraulic system of a certain type of product, hydraulic balance valves are used in several heavy-duty load-bearing circuits to improve the impact resistance of each system circuit and to maintain the stability of the system operation. However, in actual use, the consistency and interchangeability of each balancing valve is poor. After repeated investigations, it was found that there was no uniform test standard and method during the production test and delivery test of the hydraulic balance valve, resulting in insufficient product testing, and the consistency and interchangeability of the hyd...
