[0021] 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.

[0022] Please see Figure 1-4This utility model provides a technical solution: a manual regulating valve to prevent misoperation, including a valve body 1 and a locking sleeve 3. The inner wall of the locking sleeve 3 is rotatably connected to the top of the valve body 1. The inner wall of the valve body 1 is rotatably connected to a locking body 4 via an adjusting valve rod 5, and the outer wall of the adjusting valve rod 5 is rotatably connected to the inner wall of the valve body 1. A temperature acquisition interface 8 is inserted into the bottom of the valve body 1, which can be connected to a temperature acquisition device to obtain temperature information in the system and provide a reference for flow regulation. A V-shaped regulating ball 7 is rotatably connected to the inner wall of the valve body 1.

[0023] A valve seat 6 is fixedly installed on the inner wall of the valve body 1. The top of the regulating valve rod 5 is fixedly connected to the bottom of the lock body 4. The outer wall of the lock body 4 is rotatably connected to the inner wall of the lock sleeve 3 through a limiting ring 10. The outer wall of the limiting ring 10 is fixedly connected to the inner wall of the lock sleeve 3. The outer wall of the limiting ring 10 is also rotatably connected to the outer wall of the lock body 4. This structural design allows the lock body 4 to rotate within the lock sleeve 3 while being restricted by the limiting ring 10, thus ensuring the stability of the rotation.

[0024] The outer wall of the limiting ring 10 is rotatably connected to the outer wall of the lock body 4. The bottom of the regulating valve stem 5 is fixedly connected to the connecting block 9. The bottom of the connecting block 9 is inserted into the top of the V-shaped regulating ball 7. The outer wall of the connecting block 9 is rotatably connected to the inner wall of the valve body 1. The outer wall of the valve seat 6 is slidably connected to the outer wall of the V-shaped regulating ball 7.

[0025] This manual regulating valve, designed to prevent misoperation, mainly consists of a valve body 1, a locking sleeve 3, a locking body 4, a regulating valve stem 5, a V-shaped regulating ball 7, a valve seat 6, a limit ring 10, and a connecting block 9. It is suitable for heating, central air conditioning, and user heating systems. Through its unique structural design, it achieves regulation of user flow and prevents misoperation. Its specific working principle is as follows:

[0026] The valve body 1 serves as the basic structure of the entire regulating valve, providing space for the installation and operation of other components. A temperature acquisition interface 8 is inserted at the bottom of the valve body 1, which can be connected to a temperature acquisition device to obtain temperature information in the system and provide a reference for flow regulation.

[0027] The inner wall of the locking sleeve 3 is rotatably connected to the top of the valve body 1. Together with the lock body 4 and the limiting ring 10, it forms a horseshoe-type locking device to prevent misoperation. The outer wall of the lock body 4 is rotatably connected to the inner wall of the locking sleeve 3 through the limiting ring 10, and the outer wall of the limiting ring 10 is fixedly connected to the inner wall of the locking sleeve 3. The outer wall of the limiting ring 10 is also rotatably connected to the outer wall of the lock body 4. This structural design allows the lock body 4 to rotate within the locking sleeve 3, while being restricted by the limiting ring 10, ensuring the stability of the rotation. The lock body 4 plays a crucial locking role. When the valve does not need to be adjusted, the lock body 4 is locked by the key opposite to it, restricting the rotation of the regulating valve stem 5, thereby protecting the valve from being opened and adjusted by others and preventing misoperation.

[0028] The regulating valve stem 5 is a key transmission component for achieving flow regulation. Its top is fixedly connected to the bottom of the lock body 4, and a connecting block 9 is fixedly connected to the bottom. When it is necessary to regulate the flow, the lock body 4 is first turned by a specific key, which in turn causes the regulating valve stem 5 to rotate.

[0029] The bottom of the connecting block 9 is inserted into the top of the V-shaped adjusting ball 7, and the outer wall of the connecting block 9 is rotatably connected to the inner wall of the valve body 1. This allows the adjusting valve rod 5 to rotate through the connecting block 9 to drive the V-shaped adjusting ball 7 to rotate inside the valve body 1. The valve seat 6 is fixedly installed on the inner wall of the valve body 1, and its outer wall is slidably connected to the outer wall of the V-shaped adjusting ball 7, providing support and sealing for the rotation of the V-shaped adjusting ball 7.

[0030] The V-shaped regulating ball 7 is the core component for achieving linear flow regulation. When the regulating valve stem 5 drives the V-shaped regulating ball 7 to rotate, the relative position between the V-shaped regulating ball 7 and the valve seat 6 changes, thereby changing the channel area through which the fluid passes through the valve. Depending on the rotation angle, the channel area will increase or decrease accordingly, thus achieving regulation of the fluid flow rate through the valve.
