Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides as Figures 1 to 4An adjustable flow control device for water reducer production shown in the figure includes a control valve 1. Both ends of the control valve 1 are connected with first connection flanges 2 through conduits. On both sides of the control valve 1, there are pipelines 3 for conveying water reducer. At the end of the pipeline 3, a second connection flange 4 is installed. On the top of the control valve 1, a box body 5 is fixed. On both sides of the box body 5, movable seats 6 are arranged. Inside the cavity of the movable seat 6, two groups of clamps 7 are rotatably connected through movable shafts. On the side of the clamp 7 close to the control valve 1, a positioning column 8 is fixed, which is docked with the mounting holes on the first connection flange 2 and the second connection flange 4. Inside the cavity of the box body 5, an adjusting component 9 for relatively moving the movable seat 6 is arranged;

[0023] By driving the movable seats 6 on both sides to move towards the middle through the adjusting component 9, then the clamps 7 movably arranged at the bottom of the movable seats 6 are clamped on the outer side of the pipeline 3. At the same time, the positioning column 8 is inserted into the mounting holes on the first connection flange 2 and the second connection flange 4, and the pipeline 3 and the control valve 1 are docked by using the first connection flange 2 and the second connection flange 4. The operator only needs to operate the worm 94 inside the box body 5 to disassemble and assemble the pipelines 3 on both sides synchronously, and the operation is convenient and fast.

[0024] The adjusting component 9 includes a bidirectional threaded sleeve 91 rotatably arranged in the cavity of the box body 5 through a bearing. At both ends inside the cavity of the bidirectional threaded sleeve 91, screw rods 92 are threadedly connected. The screw rods 92 penetrate through the box body 5 and are fixed to the movable seat 6. In the middle section of the bidirectional threaded sleeve 91, a worm gear 93 is fixed. Inside the cavity of the box body 5, a worm 94 is installed. The side of the worm 94 facing the worm gear 93 is meshed. Through the cooperation of the worm 94 and the worm gear 93, the bidirectional threaded sleeve 91 is driven to rotate, so that the screw rods 92 move telescopically inside the bidirectional threaded sleeve 91, thereby regulating the distance between the movable seats 6 and facilitating the disassembly and assembly of the first connection flange 2 and the second connection flange 4 by using the clamps 7.

[0025] The control valve 1 includes a shell 101. Inside the shell 101, a fixed seat 102 is fixed. Flow notches are opened on both sides of the fixed seat 102. Inside the cavity of the fixed seat 102, an adjusting plate 103 is slidably arranged. On the front of the shell 101, a threaded rod 104 is threadedly connected through a threaded sleeve. One end of the threaded rod 104 penetrates into the cavity of the shell 101 and is rotatably connected to the adjusting plate 103 through a bearing. The other end of the threaded rod 104 is fixed with a rotating handle. By driving the adjusting plate 103 to move inside the fixed seat 102 through the threaded rod 104, the flow rate is controlled by the amount of occlusion of the flow notches by the adjusting plate 103.

[0026] A cover plate 10 is hinged to the front of the box body 5. A lock hole 11 is provided at one end of the worm 94. The box body 5 can be covered by the cover plate 10, and then the worm 94 can be rotated by using a tool through the lock hole 11.

[0028] Two groups of limiting rods 14 are fixed on the opposite sides of the movable seat 6. The end of the limiting rod 14 far from the movable seat 6 penetrates into the inner cavity of the box body 5. Through the arrangement of the limiting rods 14, it is convenient to limit the movable seat 6 and prevent the movable seat 6 from shaking under the movement of the screw rod 92, resulting in the deviation of the position of the clamp 7.

[0029] Two groups of positioning rods 15 are fixed in the inner cavity of the fixed seat 102. Positioning holes for clamping the positioning rods 15 are formed on the adjusting plate 103. The adjusting plate 103 can be positioned through the positioning rods 15 to prevent the adjusting plate 103 from shaking and affecting the fitting degree between the adjusting plate 103 and the fixed seat 102.

[0030] During specific use, the control valve 1 is moved between the pipelines 3, the first connecting flange 2 and the second connecting flange 4 are butted, and then the clamp 7 is sleeved on the outer side of the pipeline 3. A tool is inserted into the lock hole 11 to rotate the worm 94. The worm 94 drives the bidirectional threaded sleeve 91 to rotate through the worm gear 93, so that the movable seat 6 moves towards the middle in cooperation with the screw rod 92. During this period, the positioning column 8 penetrates through the mounting holes on the first connecting flange 2 and the second connecting flange 4. Continuing to rotate the worm 94, the clamp 7 tightly fits the second connecting flange 4 on the outer side of the first connecting flange 2, and the butt joint installation is completed.
