[0002] The flanged static balancing valve is a fluid control device, mainly used in fluid pressure control systems in the industrial and construction fields to ensure that the pressure of the fluid remains stable when it flows in the pipeline. This valve adjusts the flow rate by adjusting the cross-sectional area of the fluid channel, thereby maintaining the pressure balance of the system. It is usually composed of a valve body, a valve cover, a valve disc, a sealing gasket and other components. The valve cover is the part covering the upper end of the valve disc and used to seal the entire valve. The sealing gasket under the valve cover is a key component to ensure the sealing of the valve. As the use time increases, the sealing gasket may be worn or damaged and needs to be replaced regularly. If the valve cover is designed to be easy to disassemble and assemble, it can greatly simplify maintenance work and reduce downtime.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a flange type static balancing valve, comprising a mounting end 1, a valve cover 2 is fixedly connected inside the mounting end 1, a positioning cylinder 3 is fixedly connected to the outer wall of the valve cover 2, a threaded rod 4 is threadedly connected inside the valve cover 2, a handle 5 is fixedly connected to one end of the threaded rod 4, a rotating block 6 is rotatably connected to the other end of the threaded rod 4, a push block 7 is fixedly connected to the outer wall of the rotating block 6, the outer wall of the push block 7 is slidably connected to the inner wall of the positioning cylinder 3, a clamping block 8 is slidably connected inside the positioning cylinder 3, a telescopic rod 9 is fixedly connected to the outer wall of the clamping block 8, a spring 10 is sleeved on the outer wall of the telescopic rod 9, both ends of the spring 10 are fixedly connected to the outer wall of the clamping block 8, a limiting component is arranged on the inner wall of the positioning cylinder 3, and the limiting component comprises a limiting block 11, and the outer wall of the limiting block 11 is fixedly connected to the inner wall of the positioning cylinder 3;
[0024] Specifically, first, the handle 5 is driven. By driving the handle 5 to rotate, the threaded rod 4 will start to rotate inside the valve cover 2. As the threaded rod 4 rotates, one end of the threaded rod 4 will rotate synchronously inside the handle 5, thereby driving the rotating block 6 to start working. The rotating block 6 is cleverly designed and can effectively convert the rotational motion of the threaded rod 4 into linear motion, thereby pushing the push block 7 to slide inside the positioning cylinder 3. In this process, the push block 7 will apply pressure to the two clamping blocks 8, so that they move in the opposite direction inside the positioning cylinder 3. The spring 10 will be stretched during the movement of the clamping block 8, ensuring the stability of the clamping block 8 during the movement. As the clamping block 8 moves, it slides inside the positioning cylinder 3 and the mounting end 1, thereby realizing a convenient connection between the valve cover 2 and the mounting end 1. In order to ensure that the movement of the push block 7 will not damage the spring 10, a limit block 11 is specially added in the design. The function of the limit block 11 is to limit the moving range of the push block 7 to prevent it from exceeding the safety range and causing unnecessary pressure or damage to the spring 10, thereby realizing a convenient connection between the valve cover 2 and the mounting end 1, and allowing the internal valve core to be quickly disassembled and assembled.
[0025] Reference Figure 1 and Figure 3 The outer wall of the valve cover 2 is provided with a hand wheel 12, the bottom of the mounting end 1 is fixedly connected with an outer shell 13, the outer wall of the outer shell 13 is fixedly connected with a sealing ring 14, the bottom of the outer shell 13 is fixedly connected with a fixing ring 15, one end of the fixing ring 15 is rotatably connected with a movable ring 16, the other end of the fixing ring 15 is rotatably connected with a screw 17, the outer wall of the screw 17 is threadedly connected with a nut 18, the outer wall of the sealing ring 14 is attached with a connecting pipe 19, the outer wall of the connecting pipe 19 is arranged between the fixing ring 15 and the movable ring 16, and the inner wall of the movable ring 16 is attached to the outer walls of the outer shell 13 and the fixing ring 15;
[0026] Specifically, firstly, the connecting pipe 19 is correctly placed on the inner wall of the fixing ring 15 to ensure the close fit between the connecting pipe 19 and the outer shell 13. By accurately placing the connecting pipe 19 in the fixing ring 15, the stability and sealing of the valve are ensured. Next, the sealing ring 14 on the outer wall of the outer shell 13 is used to ensure the seamless connection between the connecting pipe 19 and the outer shell 13, thereby preventing any possible leakage. Then the movable ring 16 is rotated to make it closely fit with one end of the fixing ring 15, thereby ensuring the stability and firmness of the valve structure and the close fit between the movable ring 16 and the fixing ring 15. Next, the screw 17 is accurately rotated to the inside of the movable ring 16 to ensure that the screw 17 can smoothly pass through the movable ring 16 and be tightly combined with it. Finally, the nut 18 is driven to rotate on the outer wall of the screw 17, thereby tightly connecting the fixing ring 15 and the movable ring 16. By rotating the driving nut 18, the tightness between the fixing ring 15 and the movable ring 16 can be accurately adjusted, thereby realizing the installation of the static balancing valve.
[0027] Working principle: When the flange type static balancing valve is needed, first drive the handle 5 to drive the threaded rod 4 to rotate inside the valve cover 2, and then make one end of the threaded rod 4 rotate inside the handle 5, so that the rotating block 6 drives the push block 7 to slide inside the positioning cylinder 3, thereby applying pressure to the two blocks 8, so that the two blocks 8 move in opposite directions inside the positioning cylinder 3. This process will drive the spring 10 to stretch, and then make the block 8 slide inside the positioning cylinder 3 and the mounting end 1, so as to achieve the effect of facilitating the connection between the valve cover 2 and the mounting end 1. In this process, the push block 7 is limited by the limit block 11 The movement of the push block 7 is prevented from damaging the spring 10, thereby facilitating the disassembly and assembly of the internal valve core. Then, the connecting pipe 19 is placed on the inner wall of the fixed ring 15 to make the connecting pipe 19 fit with the outer shell 13, and the sealing is achieved through the sealing ring 14 on the outer wall of the outer shell 13. Then, the movable ring 16 is rotated to fit with one end of the fixed ring 15, and then the screw 17 is rotated to the inside of the movable ring 16. Finally, the nut 18 is driven to rotate on the outer wall of the screw 17 to tightly connect the fixed ring 15 and the movable ring 16, thereby achieving the installation of the static balancing valve.
