[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 5As shown, this utility model provides an oil extraction regulating valve, including a valve body 1 and through pipes 2 installed on the left and right sides of the valve body 1. A valve seat 3 is screwed to the center of the bottom of the valve body 1, which facilitates the installation and removal of the valve seat 3. The bottom of the valve seat 3 has a valve port. A sealing ring 4 is fixedly sleeved on the upper part of the outer wall of the valve seat 3. The sealing ring 4 can seal the connection between the valve seat 3 and the valve body 1 to ensure sealing. The sealing ring 4 is supported at the bottom of the valve body 1. Two handles 5 are symmetrically welded to the outer wall of the valve seat 3, which facilitates the application of force to turn the valve seat 3. A top cover 6 is screwed to the center of the top of the valve body 1, which facilitates the installation and removal of the top cover 6. A sealing cover 7 is integrally die-cast on the top of the top cover 6. The sealing cover 7 can seal the connection between the top cover 6 and the valve body 1 to ensure sealing. The sealing cover 7 is supported at the bottom of the valve body 1. A valve stem 9 is installed on the top of the valve body 1 and the middle of the sealing cover 7. A handle 11 is connected to the top of the valve stem 9 by screws. The valve stem 9 can be rotated by the handle 11 to open and close the valve port of the valve seat 3 through the valve disc 10. The valve stem 9 passes through the top cover 6 and is connected to the valve disc 10 located on the top of the valve seat 3 by screws. The side wall of the sealing cover 7 has two fixed parts 8 that are symmetrically die-cast and integrally formed. The die-cast integral structure has high strength and is not easily damaged. The fixed parts 8 are screwed to the top of the valve body 1. The fixed parts 8 are fixed by the fixed screws, so that the sealing cover 7 can be stably fixed to the top of the valve body 1, and the sealing cover 7 and the top cover 6 can be prevented from loosening. Two grips 12 are symmetrically welded to the top of the sealing cover 7. The two grips 12 make it easy to apply force to turn the sealing cover 7.

[0019] Specifically, both ends of the grip 11 are connected to circular limiting parts, and the top of the grip 11 is symmetrically provided with two rows of concave holes, which can improve the stability when holding and facilitate smooth rotation of the grip 11.

[0020] Furthermore, the top of the sealing ring 4 has a groove, and a sealing ring 13 is nested inside the groove. The sealing ring 13 abuts against the corresponding side of the bottom of the valve body 1, further increasing the sealing performance at this point and preventing leakage at the connection between the valve seat 3 and the valve body 1.

[0021] Furthermore, the inner side of the through pipe 2 is threaded with a connecting ring 14. The threaded connection makes it easy to install and remove the connecting ring 14. A filter screen 15 is nested inside the connecting ring 14. The filter screen 15 can filter impurities in the oil and prevent impurities from clogging the inside of the valve body 1.

[0022] It is worth noting that a support ring 17 is installed on the inner side of the connecting pipe 2 to prevent the connecting ring 14 from being screwed in too deeply and becoming difficult to unscrew. The support ring 17 is supported on the corresponding side of the connecting ring 14. The side of the connecting ring 14 away from the support ring 17 is connected to a handle 16 by a screw, which makes it easy to apply force to turn the connecting ring 14.

[0023] It is worth noting that a first flange is welded to the end of the through pipe 2 away from the valve body 1, which facilitates the connection of external pipes to the through pipe 2. A second flange is welded to the bottom of the valve seat 3, which facilitates the connection of external pipes to the valve seat 3.

[0024] It is worth mentioning that a nameplate 18 is attached to the front side of the valve body 1, and a protective film is attached to the surface of the nameplate 18 to prevent wear. The surface of the nameplate 18 is marked with the parameter information of the current device for easy reference.

[0025] The device's "front, back, left, and right" perspectives are... Figure 1 The direction shown in the diagram is the reference.

[0026] Working principle: The device is as follows Figure 1 During installation and use, the filter screen 15 intercepts impurities in the oil, preventing them from entering the valve body 1 and causing blockages. The filter screen 15 is screwed to the inside of the connecting pipe 2 via the connecting ring 14. To clean it, first disconnect the connecting pipe 2 from the external pipeline, and then unscrew it using the handle 16. Cleaning the filter screen 15 is relatively convenient. If internal maintenance is required, simply unscrew the valve seat 3 using the two handles 5, then unscrew the fixing screws and unscrew the top cover 6 using the two grips 12. After that, internal maintenance of the valve body 1 is relatively convenient. The main body of the device can be easily disassembled, making internal maintenance more convenient.
