[0002] A throttle valve is a valve that controls the flow of a fluid by changing the throttle section or throttle length. A throttle valve and a check valve can be connected in parallel to form a one-way throttle valve. A throttle valve and a one-way throttle valve are simple flow control valves. In a quantitative pump hydraulic system, a throttle valve and a relief valve can be used together to form three types of throttle speed control systems, namely, an oil inlet throttle speed control system, an oil return throttle speed control system, and a bypass throttle speed control system.

[0023] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0024] Embodiment:

[0025] Example 1

[0026] The present application discloses a speed regulating throttle valve with a quick-insert connector. Different from the conventional speed regulating throttle valve in which both ends need to be fixedly connected by threaded connection, the present application provides a quick-connect structure 3 on the connector 2. The quick-connect structure 3 can be used to insert a light tube into the quick-connect structure 3 and fix it to generate a tightening force, thereby quickly completing the operation while stabilizing the device connection.

[0027] like Figure 1-4 As shown, the middle of the valve body 1 is connected with a connector 2, which is in communication with the inside of the valve body 1. A quick-connect structure 3 is provided on the connector 2, and the quick-connect structure 3 includes a collar 32 for fixing the light tube and providing locking. The collar 32 is connected to the connector 2. The collar 32 is a trumpet-shaped structure, that is, a trumpet structure similar to a suona, but with a larger flange. The collar 32 includes a curling edge formed by turning the edge of its large port toward the small port side and a conical trumpet body. Notches are provided on the curling edge and the trumpet body, and the notch is mainly used for deformation buffering of the collar 32. Due to the special conical inner wall structure, the collar 32 will swell. Furthermore, the edge of the curling and the inner wall of the clamping hole are in compression contact, so that the clamp ring 32 is clamped in the inner clamping sleeve 31. When the small port of the horn body expands due to the pushing action, the light tube to be connected can pass through; when the pushing force disappears, the small port of the horn body is released and shrinks, and the hose is naturally clamped to prevent it from falling off. The inner clamping sleeve 31 is connected to an end cap, which is threadedly connected to the connector 2, and the inner clamping sleeve 31 is squeezed by rotating the end cap.

[0028] Example 2

[0029] On the basis of Example 1, Figure 1-4 As shown, a hollow valve core 12 is installed at the bottom end of the valve body 1, and an adjusting knob 4 is rotatably connected to the top end of the valve body 1. A friction groove is provided at the outer end of the adjusting knob 4, and a valve stem 41 is connected to the bottom end of the adjusting knob 4. The top end of the valve stem 41 is threadedly connected to the inner wall of the top end of the valve body 1, and an abutment sleeve 42 is connected to the bottom end of the valve stem 41. A one-way sealing ring 43 is provided at the bottom end of the valve body 1. An inclined thin edge is provided on the outside of the one-way sealing ring 43, and the outer edge of the thin edge is inclined toward the end of the valve body 1 where the valve core 12 is installed. The bottom end of the abutment sleeve 42 abuts against the top end of the one-way sealing ring 43. The valve stem 41 is driven to move up and down by rotating the adjusting knob 4, thereby changing the flow rate of the device. The one-way sealing ring 43 has elastic force to ensure that the top end of the one-way sealing ring 43 is in contact with the bottom end of the abutment sleeve 42.

[0030] Example 3

[0031] On the basis of Example 2, Figure 1-4 As shown, a connecting pipe 11 is provided at the bottom end of the valve body 1, and a threaded connection portion is provided on the outer wall of the connecting pipe 11. The device is fixed at a designated position through the threaded connection portion, and the firmness of the device connection is ensured.
