[0002] A balancing valve is a type of valve used to regulate parameters such as flow rate and pressure in fluid systems. It is widely used in air conditioning, heating, water supply and drainage, and other fields. Traditional balancing valves are usually of an integral structure, with components fixed together by welding or flange bolts.

[0003] When a balancing valve malfunctions and requires maintenance, the entire valve must be removed from the system and completely disassembled before the faulty component can be repaired or replaced. This maintenance method is not only time-consuming and labor-intensive, but also costly. Furthermore, the disassembly process can easily damage other components, affecting the valve's lifespan and reliability.

[0004] Therefore, this utility model provides a modular balancing valve that is easy to maintain, in order to solve the above problems. Utility Model Content

[0017] Beneficial effects

[0018] This invention provides a modular balancing valve that is easy to maintain. Compared with the prior art, it has the following advantages:

[0019] 1. This easy-to-maintain modular balance valve allows for quick connection by first inserting the positioning rod into the extension tube for positioning, then pushing the main sliding sleeve to slide diagonally downwards along the separating sleeve. This causes the threaded sliding sleeve to move synchronously, and the positioning strip prevents them from shifting. Once the sliding sleeve reaches a certain position, it disengages from the positioning strip and, after rotation, screws onto the outer wall of the extension tube, thus securing the separating sleeve. For separation, rotate the threaded sliding sleeve in the opposite direction to disengage it from the extension tube. Once the sliding groove of the positioning strip aligns with the groove of the main sliding sleeve, push the main sliding sleeve diagonally upwards to quickly separate the separating sleeve from the extension tube. The process is simple.

[0020] 2. This easy-to-maintain modular balance valve features a spring-loaded pin that tightly engages with a threaded sleeve, preventing rotation caused by external impacts. Pulling the lever disengages the pin, quickly releasing the restriction and allowing the threaded sleeve to rotate in the opposite direction. Turning the handwheel rotates the lead screw, which, being integrated with the limit block and constrained by the limit groove, moves along the lead screw. This movement, in turn, drives the valve plug via the long rod, easily controlling the flow of the liquid outlet. Attached Figure Description

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0029] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Reference Figures 1 to 5This application provides a modular balance valve that is easy to maintain, including a main valve body 1. A module separation assembly 2 is provided on the outer wall of the main valve body 1. The module separation assembly 2 includes an extension tube 21, which is fixedly connected to the outer wall of the main valve body 1 and communicates with the interior of the main valve body 1. The module separation assembly 2 also includes a separation sleeve 28, one end of which is fixedly connected to a positioning rod 213, which is inserted into the interior of the extension tube 21. A main sliding sleeve 210 is slidably connected to the outer wall of the separation sleeve 28, and a threaded sliding sleeve 211 is rotatably connected to one end of the main sliding sleeve 210. The inner wall of the threaded sliding sleeve 211 is threadedly connected to the outer wall of one end of the extension tube 21. A positioning slide bar 29 is fixedly connected to the outer wall of the main sliding sleeve 210, and the positioning slide bar 29 is slidably connected to the interior of the main sliding sleeve 210 and the threaded sliding sleeve 211.

[0031] In practice: First, the positioning rod 213 is inserted into the extension tube 21 to complete the initial quick docking and positioning. Then, the main sliding sleeve 210 is pushed to slide obliquely downward along the separating sleeve 28. The main sliding sleeve 210 will also push the threaded sliding sleeve 211 to slide together. The positioning strip 29 fixed on the outer wall of the separating sleeve 28 can effectively prevent the main sliding sleeve 210 and the threaded sliding sleeve 211 from shifting positions when sliding. When sliding to a certain position, due to the length of the positioning strip 29, the threaded sliding sleeve 211 can disengage from the positioning strip 29. With the limitation of 9, the inner wall of the sleeve can be rotated to screw it onto the outer wall of the extension tube 21, thereby quickly fixing the separating sleeve 28. When separation is required, the threaded sleeve 211 can be rotated in the opposite direction to disengage it from one end of the extension tube 21. At the same time, the groove for the positioning slide 29 to slide is aligned with the groove of the main sleeve 210, which pushes the main sleeve 210 to move obliquely upward, thereby quickly separating the separating sleeve 28 from the extension tube 21. The process is simple and convenient.

[0032] Reference Figures 1 to 5In one aspect of this embodiment, a protrusion 22 is fixedly connected to the outer wall of the extension tube 21, a reinforcing rod 23 is fixedly connected to one side of the protrusion 22, and an assembly block 24 is fixedly connected to one end of the reinforcing rod 23. A pin 27 is slidably connected inside the assembly block 24, a spring 26 is fixedly connected to one side of the inner wall of the assembly block 24, one end of the spring 26 is fixedly connected to one side of the pin 27, and a pull rod 25 is also fixedly connected to one side of the assembly block 24, passing through one side of the assembly block 24. One end of the pin 27 can be inserted into the inside of the threaded sleeve 211. A lead screw 219 is rotatably connected between the inner walls of the separating sleeve 28, a nut block 217 is threadedly connected to the outer wall of the lead screw 219, a limit groove 212 is formed on the inner wall of the separating sleeve 28, a limit block 218 is fixedly connected to the outer wall of the nut block 217, the limit block 218 is slidably connected to the inside of the limit groove 212, and a handwheel 216 is fixedly connected to one end of the lead screw 219. A long rod 214 is fixedly connected to one side of the nut block 217. The long rod 214 passes through one end of the separating sleeve 28, and a valve plug 215 is fixedly connected to one end of the long rod 214.

[0033] In practice: the spring force of the spring 26 causes the pin 27 to be tightly inserted into the threaded sleeve 211, which can restrict the threaded sleeve 211 and prevent it from rotating due to external force collision. When it is necessary to rotate the threaded sleeve 211 in the opposite direction to separate it, the pull rod 25 can be pulled to drive the pin 27 to disengage from the threaded sleeve 211, thereby quickly releasing the restriction on the threaded sleeve 211. By turning the handwheel 216, the screw 219 can be rotated. Since the nut block 217 and the limit block 218 are a whole, and the limit block 218 is restricted from sliding in the limit groove 212, when the screw 219 rotates, the nut block 217 can be moved along the screw 219. The nut block 217 then drives the long rod 214 to move, and the long rod 214 then drives the valve plug 215 to move, so as to easily control the flow of liquid outlet.

[0034] All electrical devices in this plan are powered by an external power source.

[0035] Working principle: First, the positioning rod 213 is inserted into the extension tube 21 for initial positioning, pushing the main sliding sleeve 210 to slide along the separating sleeve 28, while simultaneously driving the threaded sliding sleeve 211 to move synchronously. During the process, the positioning slide bar 29 on the outer wall of the separating sleeve 28 prevents the main sliding sleeve 210 from shifting from the threaded sliding sleeve 211. When sliding to the end of the positioning slide bar 29, the threaded sliding sleeve 211 is released from its restraint and can rotate, its inner wall being screwed to the outer wall of the extension tube 21, thus fixing the separating sleeve 28. At the same time, the spring 26 in the assembly block 24 pushes the pin 27 to insert into the threaded sliding sleeve 211, preventing it from loosening due to external impact.

[0036] During the separation operation, pulling the lever 25 causes the pin 27 to disengage from the threaded sleeve 211. After the restriction is released, the threaded sleeve 211 is rotated in the opposite direction to disengage it from the extension tube 21. When the positioning slide 29 is collinear with the groove of the main sleeve 210, the main sleeve 210 is pushed to move obliquely upward, thereby achieving rapid separation of the separation sleeve 28 and the extension tube 21.

[0037] In terms of flow control, rotating the handwheel 216 drives the lead screw 219 to rotate. Since the nut block 217 is restricted from sliding within the limiting groove 212 by the limiting block 218, the rotation of the lead screw 219 causes the nut block 217 to move along the lead screw 219, which in turn drives the valve plug 215 to move via the long rod 214, thus achieving precise control of the liquid outlet flow rate. The entire structure, through mechanical linkage and limiting design, ensures connection stability while enabling quick assembly / disassembly and flow adjustment, achieving a modular effect that facilitates maintenance.
