Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a regulating valve which is easy to install. Background Art

[0002] The regulating valve, also known as the control valve, is a final control element in the field of industrial automation process control that changes process parameters such as medium flow, pressure, temperature, and liquid level through power operation by receiving the control signal output by the regulating control unit. When the valve body is connected to the pipeline, a sealing flange assembly is generally used for connection. Since the traditional flange has an internal hole, the bolt passes through the hole and is connected to the nut, thereby clamping the two flanges together.

[0003] For example, the prior art Chinese utility model patent (CN217463694U) discloses a regulating valve that is easy to install, including a regulating tube, one end of which is provided with a fixing mechanism. By turning the knob, the threaded shaft rotates and the threaded shaft drives the control frame to move upward, so that the regulating rod rotates with the regulating shaft as the axis on the inner side of the regulating frame and the regulating rod drives the clamping rod to rotate, thereby achieving the purpose of easy fixed installation.

[0004] However, the prior art has the following defects: the device only applies a clamping force in a cross-sectional direction to the valve body and the pipeline, and applies a force in the flow direction of the pipeline, resulting in poor sealing performance of the valve body and the pipeline.

[0005] Based on this, a regulating valve that is easy to install is now provided to eliminate the disadvantages of the existing devices. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, Figures 1-4 As shown, a regulating valve that is easy to install includes: a regulating valve body 100 and an external pipe 101 arranged on both sides of the regulating valve body 100, a flange 102 is provided at the connection between the regulating valve body 100 and the external pipe 101, and a transmission mechanism is provided on the regulating valve body 100 at the flange 102, and the transmission mechanism includes a rotating disc 200, which is threadedly connected to the regulating valve body 100, and four arc-shaped limiting grooves 201 are provided on the rotating disc 200, and a fixing component is provided in the arc-shaped limiting groove 201. The regulating valve body 100 is connected to the external pipe 101, and the rotating disc 200 is rotated to move toward the position of the regulating valve body 100, while driving the fixing component to fix the regulating valve body 100 and the external pipe 101.

[0026] In this embodiment, if Figure 1-Figure 3As shown, the fixing member includes a sliding rod 301, the sliding rod 301 is slidably connected to the arc-shaped limiting groove 201, the sliding rod 301 is fixedly connected to the limiting block 302 at one end close to the regulating valve body 100, the other end of the sliding rod 301 is fixedly connected to one end of the connecting rod 303, the other end of the connecting rod 303 is fixedly connected to one end of the fixing plate 304, the other end of the fixing plate 304 is fixedly connected to the baffle 305, the outer end of the regulating valve body 100 is fixedly connected to the limiting rod 306, and the limiting rod 306 is provided with a sliding rod corresponding to the connecting rod 303. Slot 307, the sliding rod 301 slides in the arc-shaped limit groove 201, and the limit blocks 302 and the connecting rod 303 on both sides of the sliding rod 301 limit it. When the rotating disc 200 moves, the connecting rod 303 moves with the rotating disc 200. The limit rod 306 makes the connecting rod 303 only move left and right with the rotating disc 200 and will not rotate. As the rotating disc 200 rotates, the fixed plate 304 clamps and fixes the valve body and the cross-sectional direction of the pipeline, and the baffle 305 fixed on the fixed plate 304 clamps the flow direction of the regulating valve body and the external pipeline.

[0027] In one embodiment, Figure 4 As shown, a rebound module is provided at the contact surface between the baffle 305 and the external pipe 101, and the rebound module includes a rebound block 601, which is located in the rebound groove 602 of the baffle 305. A spring 603 is provided in the rebound groove 602, and one end of the spring 603 is fixedly connected to the rebound block 601, and the other end of the spring 603 is fixedly connected to the inner wall of the rebound groove 602. As the rotating disc 200 rotates, the rebound block 601 first contacts the external pipe and compresses the spring 603 to clamp the pipe flow direction of the regulating valve body and the external pipe, and then the fixed plate 304 continuously contracts inward to clamp and fix the valve body and the pipe cross-section direction.

[0028] In one embodiment, Figure 1 As shown, a limit unit is provided on the flange 102, and the limit unit includes four limit pins 400. The external pipe 101 is provided with grooves corresponding to the limit pins 400. The four limit pins 400 are inserted into the limit pins 401, so that the valve body and the pipe will not rotate relative to each other, which makes fixed installation more convenient.

[0029] In one embodiment, Figure 1 As shown, the connection between the flange 102 and the external pipe 101 is fixedly connected with a sealing ring 500, which increases the air tightness of the connection between the pipes, prevents liquid from flowing out, and ensures the normal operation of the device.

[0030] In one embodiment, Figure 1As shown, the outer end of the rotating disc 200 is provided with anti-slip grooves 202 to increase the friction of the outer end of the rotating disc 200 to prevent sliding, making it more convenient to fix the valve body and the pipeline.

[0031] In one embodiment, Figure 4 As shown, a rubber pad is fixedly connected to the contact surface between the rebound block 601 and the external pipe 101 to prevent wear between the devices and to play a role in shock absorption.

[0032] In one embodiment, Figure 1 As shown, the four arc-shaped limiting grooves 201 are distributed circumferentially on the disc 200, so that when clamping, the force is more uniform and the clamping is tighter.

[0033] The above embodiment discloses a regulating valve that is easy to install, wherein the regulating valve body 100 is connected to the external pipe 101, and four limit pins 400 are inserted into the limit pins 400, so that the valve body and the pipe will not rotate relative to each other, making it more convenient to fix and install. The rotating disc 200 is rotated and the rotating disc 200 moves toward the position of the regulating valve body 100. The rotating disc 200 is provided with an arc-shaped limit groove 201, and the sliding rod 301 slides in the arc-shaped limit groove 201. The limit blocks 301 on both sides of the sliding rod 301 02 and the connecting rod 303 limit it. When the rotating disc 200 moves, the connecting rod 303 moves with the rotating disc 200. The limiting rod 306 makes the connecting rod 303 only move left and right with the rotating disc 200 and will not rotate. As the rotating disc 200 rotates, the rebound block 601 first contacts the external pipe and compresses the spring 603 to clamp the flow direction of the regulating valve body and the external pipe. Then the fixing plate 304 continuously contracts inward to clamp and fix the valve body and the cross-sectional direction of the pipe.

[0034] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
