Valve body automatic detection device and method

Abstract

The invention discloses a valve body automatic detection device, which comprises a mechanical operation system and an electrical control system, wherein the mechanical operation system is used for achieving blockage and air inflation of a water inlet port and a water outlet port of a valve body, and the electrical control system controls the mechanical operation system to operate during the test process. The invention further discloses a valve body automatic detection method, which comprises the steps of compiling a programmable controller according to process steps, actions and time of drain valve detection, outputting a command via the programmable controller to control a corresponding relay, and driving an electromagnetic valve to make a pneumatic device complete required actions according to a program, thereby achieving the automatic detection purpose. The valve body automatic detection device and the valve body automatic detection method adopts the program for controlling a first pneumatic mechanism and a second pneumatic mechanism to complete actions of steps automatically, automatically control the air inflation time and pressure maintaining time, and automatically detect air pressure variation, so as to judge whether the valve body is qualified or not, thereby completing the transformation from manpower to machine and from manual to automatic; in addition, the valve body automatic detection device changes the traditional water immersion detection method for many years, and completes the transformation from ''wet'' to ''dry''.

Description

technical field [0001] The invention relates to an automatic detection device for a valve body, in particular to a non-submerged automatic detection device for a drain valve and a detection method thereof. Background technique [0002] The drain valve is an important part of a fully automatic washing machine. With the continuous improvement of people's living standards, the demand for high-end household appliances is increasing, and the market demand for automatic washing machines is also growing rapidly. However, the factory inspection of the drain valve is an important link. But it has become a bottleneck restricting the increase of production. [0003] At present, the detection of drain valves in the industry still adopts the original manual detection method of immersion, that is, the water inlet and outlet of the drain valve are manually blocked, and then the valve cavity on the water inlet side and the water outlet side of the drain valve are filled respectively.
