Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] Please see Figures 1 to 2 This utility model provides an embodiment of a hand-cranked regulating valve, comprising a valve assembly and a valve body assembly, with the valve assembly located above the valve body assembly. The valve assembly includes a bracket 1, a valve stem 2, a valve plate 3, and a hand crank 4. The bracket 1 is U-shaped, with a detachable movable seat 5 mounted on its top. The top of the valve stem 2 is connected to the hand crank 4, and the valve stem 2 passes sequentially through the movable seat 5 and an opening. The valve stem 2 and the movable seat 5 are rotatably connected via bearings. The valve stem 2 is a lead screw, with a lead screw seat 6 threaded onto it. The lead screw seat 6 is fixedly connected to the valve plate 3. The valve body assembly includes two panels 7 and a U-shaped plate 8. The two panels 7 clamp the U-shaped plate 8. Each panel 7 has a flow channel 9, which is adapted to the shape of the U-shaped opening 10 of the U-shaped plate 8. The valve plate 3 is inserted into the U-shaped opening 10 from top to bottom to control the flow channel.

[0019] The bracket 1 has a bending part 11 at both ends of the bottom, and each panel 7 has a bending part 2 12 at the top. The bending part 11 and the bending part 2 12 are adapted to each other and are both provided with a first mounting through hole 13. The bending part 11 and the bending part 2 12 are locked by locking screws and nuts, thereby fixing the valve assembly and the valve body assembly.

[0020] One of the bends 11 is equipped with a bearing 14, and the bottom end of the valve stem 2 is rotatably connected to the bearing 14 to ensure that the valve stem 2 rotates smoothly.

[0021] A triangular reinforcing rib 15 is provided between the support 1 and the bending part 11 to improve the structural strength.

[0022] Both panels 7 and the U-shaped plate 8 are provided with corresponding second mounting through holes 16, which are locked together by locking screws and nuts to fix the two panels 7 and the U-shaped plate 8.

[0023] The bracket 1 has two limiting grooves 17 on its inner side. The valve plate 3 is embedded in the limiting grooves 17 at both ends. The valve plate 3 can slide up and down along the limiting grooves 17 to ensure that the valve plate 3 does not deviate when it moves. The panel 7 has a sleeve 18 extending outward from the flow channel 9 to facilitate connection with the pipeline.

[0024] The valve plate 3 has a bending part 3 19 on the top, which is an isosceles trapezoid. The movable seat 5 and the bending part 3 19 can be detached and installed, which facilitates the disassembly and maintenance of the valve plate 3. A handle 20 can be detachably installed on the hand crank 4 for easy operation.

[0025] Working principle: In operation, the hand crank 4 is turned to drive the valve stem 2 to rotate. Since the valve stem 2 is a lead screw, it is threadedly connected to the lead screw seat 6. The lead screw seat 6 drives the valve plate 3 to move up and down along the limiting groove 17. When the valve plate 3 moves downward, it is inserted into the U-shaped opening 10, blocking the flow channel. When the valve plate 3 moves upward, it is withdrawn from the U-shaped opening 10, opening the flow channel. By adjusting the position of the valve plate 3, the flow rate of the fluid can be controlled.

[0026] Since the valve assembly and valve body assembly are connected by locking screws, they can be easily disassembled for maintenance or replacement of parts. The flow port 9 is compatible with the U-shaped opening 10 and can be directly connected to the pipeline without additional interfaces. In addition, by adjusting the installation angle of the panel 7 and the U-shaped plate 8, the overall direction of the valve can be changed to adapt to different pipeline layouts.

[0027] Furthermore, the aforementioned components are all standard parts or can be manufactured by punching or bending with a stamping machine, resulting in low manufacturing costs and simple assembly, further reducing production costs.

[0028] In practical applications, the hand-cranked regulating valve of this invention can be widely used in industrial piping systems. In air conditioning and ventilation systems, the airflow of the pipes often needs to be adjusted. The user first selects the appropriate sleeve part 18 according to the pipe size and connects the pipe to the flow port 9. During installation, the valve assembly is fixed to the valve body assembly by tightening screws and nuts, eliminating the need for welding and simplifying the installation process. If the pipe layout needs to be changed at an angle, simply loosen the tightening screws, adjust the relative position of the panel 7 and the U-shaped plate 8, and then tighten them again to achieve angle adjustment. When maintenance is required, the movable seat 5 and valve plate 3 can be disassembled for cleaning or replacement, greatly reducing maintenance costs. The handle 20 on the hand crank 4 is detachable, facilitating operation in confined spaces.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
