Description
Technical Field
The utility model belongs to the technical field of mechanical detection, and particularly relates to automation equipment for one-way valve detection.
Background
Currently, a check valve assembly is composed of a valve frame, a spring, a valve core and a shell (as shown in fig. 3). In the actual detection, arrange the check valve that the assembly was accomplished in the die cavity by the manipulator, the cylinder drives sealing device and pushes down, aerifys and detects, and collocation ATEQ D620, ATEQ F620 accomplish the detection, and the detection process is in proper order: forward flow pressure drop test, reverse leakage test, forward leakage test rely on PLC control between each process, realize full-automatic circulation and detect, each detects that the process all is furnished with the waste material and kicks automatically and remove mechanism and waste recovery case, prevents that unqualified material spare from flowing.
During manual detection, a forward flow pressure drop test is realized by additionally arranging a flow meter at a product inlet and pressure meters at two ends of an air inlet/outlet under a rated flow, during actual detection, after the flow meter reaches a rated value manually through visual inspection, pressure values at two ends of the air inlet/outlet pressure meters are recorded, and a pressure difference value is obtained through an air inlet pressure value and an air outlet pressure value.
During manual detection, forward and reverse leakage tests adopt manual work to completely place products in water, and whether bubbles are generated in the products or not is observed by means of a water immersion bubble method, so that whether air leakage occurs or not is judged.
However, in the manual detection, there are the following problems: 1) because the check valve (check valve) is small in size, missing inspection is easy to occur when 100% of the whole inspection is carried out, and complaint risks exist, so that complaints and complaints of customers and even OEM (original equipment manufacturer) whole factories are caused. 2) Accurate differential pressure values and leakage values cannot be accurately monitored, and the quantification of press-fitting data is not facilitated. 3) When the manual detection is carried out, the waste materials are automatically kicked out to have an alarm function, and NG materials are easily mixed into qualified products.
Through the above analysis, the problems and defects of the prior art are as follows:
(1) because the check valve (check valve) is small in size, missing inspection is easy to occur when 100% of the whole inspection is carried out, and complaint risks exist, so that complaints and complaints of customers and even OEM (original equipment manufacturer) whole factories are caused.
(2) The prior art can not accurately monitor the accurate differential pressure value and the leakage value, and is not beneficial to the quantification of press mounting data.
(3) When the manual detection is carried out, the waste materials are automatically kicked out to have an alarm function, and NG materials are easily mixed into qualified products.
The difficulty in solving the above problems and defects is: during the assembly of the non-return valve, problems generally arise: the copper square rod of the valve core is clamped with the square hole of the valve frame, the spring is not installed, the valve core is not installed, the contact surface of the shell and the valve core is scratched, the spherical surface of the valve core is damaged, the elastic force of the spring exceeds the tolerance upper and lower limits, and the like.
The significance of solving the problems and the defects is as follows: the 3 airtight testers mainly detect the defect and kick out 100%, and the positive flow pressure drop (ATEQ D620): and (3) main detection: 1. the copper square rod of the valve core is blocked with the square hole of the valve frame, the spring force exceeds the upper limit, when the copper square rod of the valve core is blocked, the valve core can not be opened under the rated flow or the spring force exceeds the upper limit but is not completely opened, so that the pressure difference is continuously increased within the rated time and exceeds the set 22Kpa to give an alarm; reverse leakage test (ATEQ F620): the method mainly comprises the steps of detecting a neglected-installed valve core, wherein the contact surface of a shell and the valve core is scratched, the spherical surface of the valve core is damaged, when the assembling defect occurs, the contact surface of the spherical surface of the valve core and the shell cannot be completely sealed, so that leakage is caused, and a tester gives an alarm to kick out an unqualified assembling part; forward leakage test (ATEQ F620): the leakage detection method mainly detects that the spring is neglected to be installed, the elasticity of the spring exceeds the lower limit, and if the defects occur, the leakage amount exceeds the standard due to the neglected to be installed and the elasticity of the spring exceeds the lower limit under the rated small air pressure (the actual working condition is 10 Kpa). The main function of the one-way valve is that the fuel vehicle is automatically opened when being started to ensure fuel supply, and when the fuel vehicle is flamed out, the spring automatically resets to reserve certain fuel to ensure secondary normal ignition, so that the defects that the functions of the product are affected by 3 air tightness testers are completely avoided, and the condition that the delivered parts are completely qualified is ensured.
