The flow and pressure of a medium in a pipeline are sensed by the actuator with a sensor, and then the built-in controller processes the data for adjustment. The balance control of the flow and pressure of the medium in the pipeline is achieved by adjusting the position of the valve core. The Bluetooth module is used for signal transmission, thereby realizing remote monitoring and management.

The positioning convex ring 12 and the valve body 1 are coaxial, and the outer diameter of the positioning convex ring 12 corresponds to the inner diameter of the corresponding connecting pipeline 7. The valve body 1 is detachably provided with a fixing frame 3 on the side close to the inlet, and the fixing frame 3 is directly opposite to the inlet end flange 11. Two positioning pins 5 are inserted one above and one below the fixing frame. The positioning pin 5 is parallel to the center line of the valve body 1, and the head of the positioning pin 5, that is, the end thereof away from the fixing frame 3, is directly opposite to the mounting hole of the inlet end flange 11. The two positioning pins 5 are respectively inserted into the two mounting holes of the inlet end flange 11, and the head of the positioning pin 5 protrudes from the mounting hole of the inlet end flange 11, that is, the head of the positioning pin 5 protrudes from the front end surface of the inlet end flange 11. An elastic structure is provided between the positioning pin 5 and the fixing frame 3, and the positioning pin 5 can retract when the head of the positioning pin 5 is subjected to axial pressure.

[0024] The structure of the fixed frame 3 is as follows Figure 2 As shown, it includes a pipe clamp 31, which is preferably a double semicircular clamp structure. The pipe clamp 31 is used to connect and fix with the valve body. The two semicircular clamp plates of the pipe clamp 31 are radially and outwardly provided with a fixing plate 32, and each fixing plate 32 is provided with a through hole 33 for inserting a positioning pin 5, and the center line of the through hole 33 is parallel to the center line of the pipe clamp.

[0025] The structure of the positioning pin 5 is as follows Figure 3 As shown, it includes a positioning portion 51, a shoulder 52 and a mounting portion 53 arranged in sequence from top to bottom, wherein the diameter of the positioning portion 51 matches the aperture of the mounting hole on the inlet end flange 11 of the balancing valve, and the length of the positioning portion 51 is greater than the thickness of the inlet end flange 11, the head of the positioning portion 51 is a protruding spherical structure, and the bottom end of the mounting portion 53 is provided with an external threaded portion 531.

[0026] In the utility model, the fixing frame 3 is connected and fixed to the valve body 1 through the pipe clamp 31, the mounting portion 53 of the positioning pin 5 is movably inserted into the through hole 33 of the fixing frame 3, the external threaded portion 531 extends from the through hole and is provided with a nut 6, the positioning portion 51 is inserted into one of the mounting holes of the inlet end flange 11, and the head of the positioning portion 51 extends from the mounting hole, the positioning pin 5 is provided with a spring 4 between its shoulder 52 and the fixing plate 3, and the two ends of the spring 4 respectively abut against the shoulder 52 and the fixing plate 31 of the fixing frame 3, under the action of the elastic structure, the shoulder 52 is close to the rear end face of the inlet end flange 11, or the nut 6 is close to the side of the fixing plate 31 of the fixing frame 3 away from the inlet end flange 11.

At this time, a supporting and limiting structure is formed between the positioning protruding ring 12 and the inner pipe wall of the corresponding connecting pipe 7. The positioning pin 5 retracts into the mounting hole of the inlet end flange 11 under the action of the pipe flange 71, and then the valve body 1 is rotated. Since a supporting and limiting structure is formed between the positioning protruding ring 12 and the corresponding connecting pipe 7, the balancing valve can rotate around its center line which is also the center line of the corresponding connecting pipe 7. When the head of the positioning pin 5 is re-extended and inserted into the mounting hole of the pipe flange 71, it means that the mounting hole of the pipe flange 71 and the mounting hole of the inlet end flange 11 are facing each other. Bolts are used to connect and fix the pipe flange 71 and the outlet end flange 11 to realize the installation of the balancing valve and the corresponding connecting pipe 7. The device can quickly align the inlet flange 11 of the balancing valve with the mounting holes of the pipe flange 71 of the corresponding connecting pipe, that is, quickly locate the installation position of the balancing valve, and realize the rapid installation of the balancing valve.

[0028] In the process of fixing the balancing valve and the corresponding connecting pipe 7 with bolts, a fixing and disassembly-at-the-same-time fixing method is adopted, that is, after determining the installation position of the balancing valve, first use 2-4 bolts to connect and fix the inlet end flange 11 and the pipe flange 71 to achieve preliminary fixation of the balancing valve, then remove the fixing frame 3 from the valve body 1, and then remove the two positioning pins 5, and finally complete the bolts to fix the balancing valve and the corresponding connecting pipe 7.

[0029] In the present invention, the height of the positioning protruding ring 12 itself is 8-10mm, that is, the height of the positioning protruding ring 12 protruding from the front end surface of the inlet end flange 11 is 8-10mm, and a 3×30° chamfer structure 122 is provided between the end surface of the positioning protruding ring 12 and its outer circumferential surface. This structure has a guiding function, making it easy to insert the positioning ring 12 into the corresponding connecting pipe 7.
