Description

Technical Field

[0001] This utility model relates to the field of engine oil pump performance testing technology, specifically to a manual valve for an oil pump performance testing bench. Background Technology

[0002] During the performance testing of an automotive engine oil pump, it is necessary to adjust the diameter of the oil outlet pipe on the test bench and fix it during the test. The performance parameters are then determined by the oil pump speed to assess whether the pressure and flow rate are within acceptable limits. The manual valve, as a key component of the test bench, directly affects the accuracy and reliability of the test results.

[0003] In existing oil pump performance testing processes, manual valves typically employ purchased ball valves or gate valves, which are installed in the oil outlet pipeline. Their diameter is adjusted according to process parameters, and pressure and flow rates are then determined by measuring rotational speed. However, existing manual valves suffer from problems during testing, including susceptibility to loosening, irregular diameter changes, and inability to achieve precise and repeatable positioning. Utility Model Content

[0004] The purpose of this invention is to provide a manual valve for an oil pump performance test bench to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a manual valve for an oil pump performance test bench, comprising:

[0006] The manual valve body has oil pipe joints connected to both ends, and a driven plate and a fixed plate are respectively sleeved on the left and right ends of the manual valve body.

[0007] A turntable, the bottom of which is connected to a positioning plate, the positioning plate being connected to the top of the valve core of the manual valve body, and the front of the positioning plate being marked with scale marks.

[0008] Both the driven plate and the fixed plate are threaded with positioning screws, and the tail end of the positioning screw abuts against the side wall of the positioning plate.

[0009] Furthermore, the retaining plate is nested with multiple locking bolts, the tail ends of which are threaded through the driven plate and connected to a first locking nut, which enhances the stability of the driven plate and the retaining plate, while also facilitating maintenance and replacement.

[0010] Furthermore, the upper side of the positioning disk is provided with multiple threaded grooves, and the top of the positioning disk is connected to two support rods. Both ends of the two support rods are provided with screws. The lower screw and the thread are nested in the corresponding threaded groove, and the upper screw passes through the turntable and is threaded with a second locking nut, so that the connection between the positioning disk and the turntable is simple and reliable. At the same time, when the turntable rotates, the positioning disk can be driven to rotate synchronously through the two support rods.

[0011] Furthermore, the positioning plate has a mounting hole that matches the shape of the upper part of the valve core, and a third locking nut is provided in the mounting hole. The third locking nut is threaded onto the top of the valve core, making the connection simple and stable.

[0012] Furthermore, the turntable is provided with multiple grip grooves, which allows for a better grip on the turntable during operation, improving the convenience and comfort of operation.

[0013] Furthermore, a sealing ring is provided at the connection between the oil pipe joint and the manual valve body to improve sealing performance and prevent fluid leakage.

[0014] Furthermore, the driven disk and the stationary disk have the same diameter.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By using a positioning plate with scale markings on its front, the diameter can be precisely adjusted to ensure the accuracy of the test.

[0017] 2. By threading positioning screws into both the driven plate and the fixed plate, and with the tail end of the positioning screws abutting against the side wall of the positioning plate, the manual valve is effectively prevented from loosening during the test. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figures 1 to 5 The manual valve shown on the oil pump performance test bench includes:

[0028] Manual valve body 1, both ends of manual valve body 1 are connected to oil pipe joints 2, and the left and right ends of manual valve body 1 are respectively fitted with driven plate 3 and fixed plate 4.

[0029] Turntable 5, with a positioning plate 6 connected to the bottom of the turntable 5. The positioning plate 6 is connected to the top of the valve core of the manual valve body 1. The front of the positioning plate 6 is marked with scale marks. The turntable 5 is provided with multiple grip grooves 14, which makes it easier to grip the turntable 5 during operation, improving the convenience and comfort of operation.

[0030] Both the driven plate 3 and the fixed plate 4 are threaded with positioning screws 7, and the tail end of the positioning screws 7 abuts against the side wall of the positioning plate 6.

[0031] Multiple locking bolts 8 are nested on the fixed plate 4. The tail ends of the multiple locking bolts 8 pass through the driven plate 3 and are threaded with the first locking nut 9, which enhances the stability of the driven plate 3 and the fixed plate 4, and at the same time facilitates maintenance and replacement.

[0032] The upper side of the positioning disk 6 has multiple threaded grooves 15. The top of the positioning disk 6 is connected to two support rods 10. Both the upper and lower ends of the two support rods 10 are provided with screws 16. The lower screw 16 is nested in the corresponding threaded groove 15, and the upper screw 16 passes through the turntable 5 and is threaded with a second locking nut 11. This makes the connection between the positioning disk 6 and the turntable 5 simple and reliable. At the same time, when the turntable 5 rotates, it can drive the positioning disk 6 to rotate synchronously through the two support rods 10.

[0033] The positioning plate 6 has a mounting hole 12 that matches the shape of the upper part of the valve core. The mounting hole 12 has a third locking nut 13, which is threaded onto the top of the valve core, making the connection simple and stable.

[0034] A sealing ring is provided at the connection between the oil pipe joint 2 and the manual valve body 1 to improve the sealing performance and prevent fluid leakage.

[0035] The driven disk 3 and the stationary disk 4 have the same diameter.

[0036] In this invention, the positioning disc 6 is connected to the valve core of the manual valve body 1, and the turntable 5 is connected to the positioning disc 6 via two support rods 10. Rotating the turntable 5 can synchronously drive the positioning disc 6 to rotate, thereby rotating the valve core of the manual valve body 1. The front of the positioning disc 6 is provided with scale markings, which can be used to precisely adjust the flow diameter to ensure the accuracy of the test. The driven disc 3 and the fixed disc 4 are both threaded with positioning screws 7, and the tail end of the positioning screw 7 abuts against the side wall of the positioning disc 6. During adjustment, first rotate the positioning screws 7 on the driven disc 3 and the fixed disc 4 so that the tail end of the positioning screw 7 moves away from the side wall of the positioning disc 6, thereby releasing the lock on the positioning disc 6 and facilitating the rotation of the positioning disc 6. After the flow diameter is adjusted, tighten the positioning screws 7 on the driven disc 3 and the fixed disc 4 so that the tail end of the positioning screw 7 tightly abuts against the side wall of the positioning disc 6, thereby locking the positioning disc 6 and effectively preventing the manual valve from loosening during the test.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
