A hydraulic check valve automatic testing system and method

Abstract

An automatic testing system for a hydraulic check valve, including a factory testing terminal, a customer testing terminal, and a processing background; wherein, the factory testing terminal includes a liquid oil injection device, and the liquid oil injection device is connected to one end of the first oil pipe, and the other end of the first oil pipe One end is connected to a one-way valve detection area, the one-way valve detection area is connected to one end of the second oil pipe, the other end of the second oil pipe is also provided with a first valve, and the second oil pipe between the one-way valve detection area and the first valve Partially provided with a first pressure sensor. The beneficial effect of the present invention is: after passing the detection of the factory inspection end, label each qualified one-way valve, and correspond the one-way valve with the label one by one, so as to prevent customers from causing losses due to abnormal one-way valves, and change the traditional The problem of damage to the one-way valve is realized only when there is leakage in the method; at the same time, by recording the time point during installation and the time point when it is abnormal, it can be analyzed to obtain the different life spans of the one-way valve under different hydraulic environments, which is convenient for customers according to actual needs. choose.

Description

technical field [0001] The invention relates to the field of testing hydraulic accessories, in particular to an automatic testing system for a hydraulic check valve. Background technique [0002] Hydraulic valves are an indispensable type of hydraulic components in hydraulic systems, and there are many types. Among them, the one-way valve is the most widely used valve. As the name implies, the one-way valve is to ensure that the hydraulic oil flows in one direction, and the reverse is cut off without leakage. This makes it necessary for hydraulic valve manufacturers to test the check valves one by one to ensure that the above requirements can be met. [0003] The traditional one-way valve is tested to be qualified after leaving the factory, and the one-way valve is often used abnormally due to various reasons during use; in actual situations, the use of the one-way valve is rarely tested, and the detection is very cumbersome and inaccurate. Customers often cannot find the...

[0003] The traditional one-way valve is tested to be qualified after leaving the factory, and the one-way valve is often used abnormally due to various reasons during use; in actual situations, the use of the one-way valve is rarely tested, and the detection is very cumbersome and inaccurate. Customers often cannot find the abnormality of the one-way valve at the first time during use. They need to see obvious leakage before they can find out, which will cause losses.
