Description

Technical Field

[0001] This utility model relates to the field of regulating valve technology, and more specifically, to a novel remote intelligent regulating valve. Background Technology

[0002] Control valves are key components of fluid control systems, precisely adjusting valve opening based on preset signals. By altering the flow area, they effectively control fluid flow, pressure, and temperature, ensuring stable and efficient production processes. With their compact structure and sensitive operation, they are widely used in chemical, power, and construction industries, forming an indispensable part of industrial automation. Remote-controlled intelligent control valves, on the other hand, are equipped with remote control systems, transforming manual operation into remote automatic control.

[0003] In operation, remote-controlled intelligent control valves primarily rely on a motor-driven screw to raise and lower the valve core for opening and closing regulation. This screw is subject to wear. If the fluid pressure controlled by the valve is high, or if the friction between the valve core and seat is significant, the load on the screw during transmission increases, accelerating wear. Worn screws exhibit a free-spinning angle, slowing the valve's response and reducing its sensitivity, thus hindering its normal operation. Therefore, we propose a novel remote-controlled intelligent control valve. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a new type of remote intelligent regulating valve to solve the technical problem that the current screw regulation is prone to wear, which slows down the response speed of the regulating valve and reduces the regulation sensitivity.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel remote intelligent regulating valve, comprising a valve body and an regulating mechanism disposed on the valve body, wherein a valve core is disposed within the valve body, a valve stem is mounted on the upper end of the valve core, an inclined regulating hole is provided on the upper part of the valve stem, a sealing sleeve is mounted on the upper end of the valve body by bolts, the regulating mechanism comprises a telescopic tube disposed within the sealing sleeve, a triangular plate is disposed on the inner wall of the telescopic tube, two triangular plates are disposed, the two triangular plates are diagonally distributed, an regulating rod is disposed between the triangular plates, and the regulating rod is located within the regulating hole.

[0006] Preferably, an inlet is provided at the upper part of one side of the valve body, and an outlet is provided at the lower part of the side of the valve body opposite to the inlet. Both the inlet and the outlet are welded with flanges.

[0007] Preferably, mounting rods are symmetrically installed on the side ends of the sealing sleeve, and a mounting plate is provided between the mounting rods. An electric push rod is provided on the mounting plate, and the piston rod of the electric push rod is connected to the telescopic tube.

[0008] Preferably, the lower end of the sealing sleeve is closed, and an extension hole is provided on the inner wall of the bottom end of the sealing sleeve, through which the valve stem extends into the telescopic tube.

[0009] Preferably, the triangular plate is a right triangle, and a limiting groove is provided on one end of the triangular plate near the center of the telescopic tube. Limiting sliders are symmetrically arranged on the adjusting rod, and the limiting sliders are slidably installed in the limiting groove.

[0010] Preferably, the adjusting rod is inclined, and the adjusting rod has a bent portion from the middle to both ends, with the bending angle of the bent portion being ninety degrees. The bends at both ends of the adjusting rod form a Z-shape.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the design of a triangular plate and adjusting rod structure, uses the triangular plate and the Z-shaped adjusting rod to achieve the opening and closing adjustment of the regulating valve, replacing the screw adjustment. This reduces problems such as the idle angle caused by screw wear and other factors, making the opening and closing operation of the regulating valve more timely, ensuring the normal use of the regulating valve and extending its service life. It solves the problem that the current screw adjustment is prone to wear, which slows down the response speed of the regulating valve and reduces the adjustment sensitivity.

[0013] 2. This utility model also designs a limiting slider and a limiting groove structure. When the regulating valve is opened and closed, the limiting slider of the regulating rod can slide in the limiting groove of the triangular plate, which can limit the regulating rod and prevent the regulating rod from deviating from its position. The electric push rod can accurately control the moving distance of the telescopic tube, thereby accurately controlling the movement of the regulating rod, and finally achieving precise adjustment of the valve core position, meeting the high-precision control requirements of fluid flow rate, pressure and other parameters under different working conditions.

Detailed Implementation

[0021] like Figures 1 to 6 As shown, this utility model relates to a novel remote intelligent regulating valve, including a valve body 101 and an regulating mechanism 200 disposed on the valve body 101. A valve core 103 is disposed inside the valve body 101, and a valve stem 104 is installed at the upper end of the valve core 103. An inclined regulating hole 105 is opened at the upper part of the valve stem 104. A sealing sleeve 102 is installed at the upper end of the valve body 101 by bolts. The regulating mechanism 200 includes a telescopic tube 201, which is disposed inside the sealing sleeve 102. A triangular plate 202 is disposed on the inner wall of the telescopic tube 201. Two triangular plates 202 are disposed, and the two triangular plates 202 are diagonally distributed. An regulating rod 203 is disposed between the triangular plates 202, and the regulating rod 203 is located inside the regulating hole 105. This utility model uses a specially shaped adjustment structure to adjust the valve core 103, thereby opening and closing the regulating valve. It replaces screw adjustment, reduces problems such as idling angle caused by screw wear, and makes the opening and closing operation of the regulating valve more timely, ensuring the normal use of the regulating valve and improving its service life.

[0022] Specifically, an inlet is located at the upper part of one side of the valve body 101, and an outlet is located at the lower part of the side of the valve body 101 opposite to the inlet. Flanges are welded to both the inlet and the outlet. The flanges are used for installing and connecting the control valve to the fluid pipeline.

[0023] Furthermore, mounting rods 204 are symmetrically installed on the side end of the sealing sleeve 102, and a mounting plate is provided between the mounting rods 204. An electric push rod 205 is provided on the mounting plate, and the piston rod of the electric push rod 205 is connected to the telescopic tube 201. The electric push rod 205 is used to control the lifting and lowering adjustment of the telescopic tube 201, thereby adjusting the valve core 103.

[0024] It is worth noting that the lower end of the sealing sleeve 102 is closed, and an extension hole is provided on the inner wall of the bottom end of the sealing sleeve 102. The valve stem 104 extends from the extension hole into the telescopic tube 201. The extension hole facilitates the raising and lowering of the valve stem 104.

[0025] It is worth noting that the triangular plate 202 is a right triangle. A limiting groove 206 is provided on one end of the triangular plate 202 near the center of the telescopic tube 201. Limiting sliders 207 are symmetrically arranged on the adjusting rod 203, and the limiting sliders 207 are slidably installed within the limiting groove 206. When the regulating valve is opened or closed, the limiting sliders 207 of the adjusting rod 203 can slide within the limiting groove 206 of the triangular plate 202, thus limiting the adjusting rod 203 and preventing it from deviating from its position.

[0026] It is worth noting that the adjusting rod 203 is inclined, and both ends of the adjusting rod 203 have bends at a bending angle of 90 degrees, forming a Z-shape. The triangular plate 202 and the Z-shaped adjusting rod 203 work together to adjust the opening and closing of the regulating valve, replacing screw adjustment. This reduces problems such as idle rotation caused by screw wear, ensuring the normal operation of the regulating valve and extending its service life.

[0027] Working Principle: This embodiment provides a novel remote intelligent regulating valve. In use, the electric push rod 205 is remotely controlled by the existing remote control system to extend or shorten the piston rod, which can raise or lower the telescopic tube 201. When the telescopic tube 201 rises or falls, the regulating rod 203 can move left or right under the limiting action of the two triangular plates 202. As the regulating rod 203 moves left or right, the valve stem 104 can rise or fall due to the special Z-shaped shape of the regulating rod 203, thereby adjusting the position of the valve core 103 to open and close the regulating valve. The adjustment operation is simple and quick, with a fast response speed. Since no screw adjustment is used, wear will not affect the normal use of the regulating valve.

[0028] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
