Description

Manual valve of oil pump performance test bench Technical Field The utility model relates to the technical field of performance test of an engine oil pump, in particular to a manual valve of an oil pump performance test bench. Background In the performance test process of the oil pump of the automobile engine, the diameter of the oil outlet pipeline of the test board needs to be adjusted and fixed in the test process, and the performance parameters of the oil pump are used for judging whether the pressure and the flow are qualified or not through the rotation speed of the oil pump. The performance of the manual valve as a key component of the test bench directly affects the accuracy and reliability of the test results. In the existing oil pump performance test process, a manual valve is generally an outsourcing ball valve or a gate valve, is arranged in an oil outlet pipeline, is reduced according to technological parameters, and then obtains pressure and flow values through rotating speed. The existing manual valve has the problems of easy loosening, irregular change of the drift diameter, incapability of accurately positioning and the like in the test process. Disclosure of utility model The utility model aims to provide a manual valve of an oil pump performance test bench, which aims to solve the problems in the background technology. In order to achieve the purpose, the utility model provides the technical scheme that the manual valve of the oil pump performance test bench comprises: The manual valve body is connected with oil pipe joints at two ends, and a driven disc and a retention disc are respectively sleeved at the left end and the right end of the manual valve body; the bottom of the rotary table is connected with a positioning disk, the positioning disk is connected with the top of the valve core of the manual valve body, and the front surface of the positioning disk is provided with scale marks; and the driven plate and the positioning plate are respectively nested with a positioning screw in a threaded manner, and the tail end of the positioning screw is abutted against the side wall of the positioning plate. Further, a plurality of locking bolts are nested on the retention disc, the tail ends of the locking bolts penetrate through the driven disc and are sleeved with first locking nuts in a threaded mode, stability of the driven disc and the retention disc is improved, and meanwhile maintenance and replacement are convenient.
