Check valve clamping stagnation simulator

The invention discloses a one-way valve clamping stagnation simulator, which relates to the technical field of hydraulic system simulation and comprises a valve body and a valve core arranged in the valve body in a sliding manner, the one-way valve clamping stagnation simulator further comprises a push rod, the push rod is in threaded connection with one end of the valve body, one end of the push rod is located in the valve body and connected with the end of the valve element, and the other end of the push rod extends out of the valve body. The device and the method have the advantages that the device and the method are simple in structure, and different influences of clamping stagnation faults of the one-way valves at different positions on the hydraulic system can be simulated. 本发明公开了一种单向阀卡滞模拟器，涉及液压系统模拟技术领域，包括阀体，和滑动设于阀体内的阀芯；还包括：推杆，推杆与阀体的一端螺纹连接，推杆的一端位于阀体内部，且与阀芯的端头连接，推杆的另一端延伸至阀体外部，将单向阀卡滞模拟器安装于液压系统中液压阀块上，通过旋转调节推杆，可以带动阀芯在阀套内发生双向位移，进而模拟单向阀卡滞在阀芯最大开度中的任意位置，从而模拟故障对液压系统工作的影响，本发明结构简单，能够模拟单向阀在不同位置的卡滞故障对液压系统的不同影响。
