The invention belongs to the field of lubricating oil system testing, and particularly relates to a temperature and pressure difference valve testing device and method. A traditional temperature and pressure difference bypass valve performance testing device only adopts a single-cavity structure and cannot accurately test. The valve performance testing device adopts a two-cavity structure of the inner cavity and the outer cavity, the valve can fully sense the medium temperature of the inner cavity to realize opening and closing, the accuracy of a tested temperature value is high, the reliability and the stability are good, and a steel bushing (or other wear-resistant materials) is mounted on the end surface, matched with the valve, of the shell in the testing device, so that the wear is reduced, and the testing efficiency is improved. The service life of the device is prolonged, repeated use of the device is achieved, the matching face of the valve and the device is in face clearance fit, the force exerting area is increased, it is guaranteed that clamping stagnation is avoided in the guiding process, the measured performance parameters are accurate, the detachable self-locking nut is adopted for locking and fixing, and maintainability is good.
本发明属于滑油系统测试领域,具体涉及一种温度压差活门测试装置及测试方法。传统温度压差旁通活门性能测试装置仅采用单腔体结构,无法准确测定。本发明活门性能测试装置采用内腔体和外腔体两腔结构,活门可充分感受内腔体介质温度实现打开和关闭,测试温度值准确性高,可靠性、稳定性良好,且测试装置中壳体与活门配合端面安装钢衬套(或其他耐磨材料),减少磨损,延长装置的使用寿命及装置的重复使用,且活门与装置配合面采用面间隙配合方式,增大着力面积,保证导向过程中不卡滞,测定性能参数准确,且采用可拆卸自锁螺母进行锁紧固定,维修性好。
