Automatic test system and method for hydraulic check valve

Abstract

An automatic test system for a hydraulic check valve comprises a factory detection end, a client detection end and a processing background, wherein the factory detection end comprises a liquid oil injection device, one end of a first oil pipe is connected to the liquid oil injection device, a check valve detection area is connected to the other end of the first oil pipe, one end of a second oil pipe is connected to the check valve detection area, a first valve is further arranged at the other end of the second oil pipe, and a first pressure sensor is arranged on the part, between the check valve detection area and the first valve, of the second oil pipe. The automatic test system has the beneficial effects that after passing detection of the factory detection end, each qualified check valve is labeled, the check valves are in one-to-one correspondence with labels, loss to a client due to abnormity of the check valves is prevented, and the problem that in a traditional method, damage tocheck valves is realized during overflow leakage is changed; and meanwhile, different lengths of the life of the check valves under different hydraulic environments can be analyzed and obtained by recording the installation time point and the abnormity time point, and the client can make a choice conveniently according to actual demands.

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.
