[0031] According to this specific embodiment, the two connecting pipes 102 are respectively connected to the valve body 101 and are respectively located on one side of the valve body 101; the two connecting plates 103 are respectively fixedly connected to the two connecting pipes 102 and are respectively located on one side of the two connecting pipes 102; the valve body 101 is a throttle valve in the prior art, and the two connecting plates 103 are connected to the flange of the external pipeline through the two connecting components 104.

[0032] Among them, multiple connecting mechanisms 105 are respectively arranged on the connecting tube 102; the mounting seat 108 is fixedly connected to the connecting tube 102 and is located on the side of the connecting tube 102; the rotating frame 109 is rotatably connected to the mounting seat 108 and is located on one side of the mounting seat 108; the screw 110 is rotatably connected to the rotating frame 109 and is located on the inner side of the rotating frame 109; the clamping frame 111 is threadedly connected to the screw 110, and is slidably connected to the rotating frame 109, and passes through the rotating frame 109; the worm wheel 112 is fixedly connected to the screw 110 and is sleeved on the screw 110; the worm 113 is rotatably connected to the rotating frame 109 and meshes with the worm wheel 112; the knob 114 is fixedly connected to the worm 113 and is located on one side of the worm 113. The connecting disk 103 is docked with the flange of the external pipe through multiple connecting mechanisms 105; during installation, the connecting disk 103 is aligned with the flange of the external pipe, and then the rotating frame 109 is rotated so that the rotating frame 109 is buckled on one side of the flange of the external pipe, and then the knob 114 is held and the worm 113 is rotated. The worm 113 drives the worm wheel 112 to rotate, and the worm wheel 112 drives the screw 110 to rotate. The screw 110 drives the clamping frame 111 to slide and clamp against one side of the flange of the external pipe, so that the flange of the external pipe is tightly attached to the connecting disk 103; therefore, during installation, it is only necessary to rotate multiple rotating frames 109 in turn, and then tighten multiple knobs 114 in turn, thereby solving the problem that the existing throttle valve installation is more troublesome.

Then, the knob 114 is held and the worm 113 is rotated. The worm 113 drives the worm wheel 112 to rotate, and the worm wheel 112 drives the screw 110 to rotate. The screw 110 drives the clamping frame 111 to slide to be clamped on one side of the flange of the external pipe, so that the flange of the external pipe is tightly attached to the connecting plate 103, and the sealing ring 107 in the middle is clamped. Therefore, during installation, it is only necessary to rotate the multiple rotating frames 109 in turn, and then tighten the multiple knobs 114 in turn, thereby solving the problem that the existing throttle valve is relatively troublesome to install.

At this time, the sliding ring 202 is directly loosened. Under the action of the spring 303, the sliding ring 202 slides in the direction away from the valve body 101, and the multiple rotating frames 109 are driven to rotate synchronously through the multiple connecting rods 203, and are synchronously buckled on one side of the flange of the external pipe, and then it is only necessary to tighten the multiple knobs 114 in sequence; therefore, the installation process can be simplified as follows: slide the sliding ring 202 to compress the spring 303 and hold it, dock the connecting plate 103 with the flange of the external pipe, and then loosen the sliding ring 202, wait for the multiple rotating frames 109 to rotate synchronously, and be synchronously buckled on one side of the flange of the external pipe, and finally tighten the multiple knobs 114 in sequence.

Then, the connecting plate 103 is aligned with the flange of the external pipe through the multiple guide rods 106. At this time, the sliding ring 202 is directly loosened. Under the action of the spring 303, the sliding ring 202 slides in the direction away from the valve body 101, and the multiple rotating frames 109 are driven to rotate synchronously through the multiple connecting rods 203 and buckle synchronously on one side of the flange of the external pipe. Then, it is only necessary to tighten the multiple knobs 114 in sequence. Therefore, the installation process can be simplified as follows: slide the sliding ring 202 to compress the spring 303 and hold it, dock the connecting plate 103 with the flange of the external pipe, then loosen the sliding ring 202, wait for the multiple rotating frames 109 to rotate synchronously, buckle synchronously on one side of the flange of the external pipe, and finally tighten the multiple knobs 114 in sequence.
