Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to an angle regulating valve. Background Technology

[0002] Control valves are an important component of industrial automation control systems, primarily used to regulate process parameters such as flow rate and pressure of media. Based on control signals from the automation system, the valve opening is automatically adjusted to precisely control the flow rate and pressure of the media within the pipeline.

[0003] Angle control valves, as a type of control valve, are characterized by their simple flow path and low resistance, making them particularly advantageous for regulating fluids with high pressure drops, high viscosity, and those containing suspended solids and particulate matter. They prevent coking, adhesion, and clogging, and are easy to clean and self-clean. In heavy chemical industries, angle control valves generally operate under high pressure differentials and with high-viscosity media that are prone to coking and contain suspended particulate matter. In these cases, the best installation method is side inlet and bottom outlet.

[0004] Existing angle control valves are susceptible to internal structural damage due to prolonged exposure to water flow: the valve seat and valve core are prone to wear, leading to internal leakage, which only worsens over time. When the valve seat is worn, it usually needs to be replaced, but existing valve seats are not easily replaceable.

[0005] The inlet and outlet channels of an angle control valve are at right angles, resulting in a large pressure difference between them. High-pressure fluid flows directly into the valve body cavity from the inlet channel, which can easily cause significant impact on the valve body, leading to damage and affecting its service life. Utility Model Content

[0006] The purpose of this utility model is to provide an angle regulating valve to solve the problems mentioned in the background art.

[0007] To solve the above technical problems, this utility model adopts the following technical solution: an angle regulating valve, including an actuator, a valve body, a valve stem, a valve core, and a valve seat. The valve core is connected to the valve stem. The bottom of the valve body is provided with an inlet channel and the side is provided with an outlet channel. The inner wall of the valve body is provided with an annular groove corresponding to the lower end of the valve core. The bottom of the valve seat is provided with a boss that matches the annular groove. The side wall of the valve body is provided with a threaded hole that penetrates the outer side. The inner end of the threaded hole communicates with the annular groove. The side of the boss facing the threaded hole is provided with a connecting groove. A screw is threaded into the threaded hole. The inner end of the screw extends into the connecting groove. The side wall of the valve core is fitted with a buffer sleeve and the bottom is provided with a buffer assembly.

[0008] Using the above technical solution, when water flows in from the inlet channel, a buffer component is set to weaken the impact force on the valve core, extending the service life of the valve core. When the valve body is closed, the actuator controls the valve stem to descend, causing the valve core to seal with the valve seat. A buffer sleeve is set to reduce the collision force between the valve core and the valve seat, thereby extending the service life of both. When the valve seat is worn and needs to be replaced, the screw is rotated, and the screw is displaced in the threaded hole and disengaged from the connecting groove to unlock the valve seat. Then, the valve seat is pulled upward to remove it. The boss of the new valve seat is then inserted into the annular groove. The screw is rotated again, and after the screw is displaced in the threaded hole, it extends into the positioning groove, locking the valve seat and completing the installation.

[0009] As a further optimization of this utility model, the side wall of the valve seat is provided with several arc-shaped grooves along the circumference, and the inner wall of the valve body is provided with positioning grooves that correspond one-to-one with the several arc-shaped grooves. The positioning grooves are provided with positioning springs and sliding positioning blocks. The outer end of the positioning block is arc-shaped and elastically abuts against the arc-shaped groove.

[0010] Using the above technical solution, when the valve seat is installed, the positioning block pops into the positioning groove and makes a popping sound, thus confirming that the mounting groove is aligned with the threaded hole, playing a positioning role and improving installation efficiency. Several positioning blocks can play a radial clamping role for the mounting seat, improving the stability of the mounting seat during installation.

[0011] As a further optimization of this utility model, the buffer assembly includes a telescopic tube disposed at the bottom of the valve core, a damping spring disposed inside the telescopic tube, and a conical guide portion disposed at the bottom of the telescopic tube.

[0012] By adopting the above technical solutions, the flow guide can disperse the fluid and reduce its impact intensity. The damping spring is compressed under the impact of the fluid, which weakens the impact force of the fluid, thereby preventing the valve core from being directly subjected to the impact force.

[0013] As a further optimization of this utility model, the inner wall of the valve body connection of the outflow channel is arc-shaped.

[0014] By adopting the above technical solution, when the high-pressure fluid flows directly into the valve body cavity from the inlet channel, the arc-shaped surface can guide the fluid, reduce the impact force on the valve body, and extend the service life of the valve body.

[0015] As a further optimization of this utility model, a buffer pad is fixedly arranged around the inner wall of the outflow channel.

[0016] By adopting the above technical solutions, when high-pressure fluid flows directly from the inlet channel into the valve body cavity and then into the outlet channel, the buffer pad is reduced and the impact force on the valve body is decreased, thus extending the service life of the valve body.

[0017] As a further optimization of this utility model, a rotating rod is provided vertically at the outer end of the screw.

[0018] The beneficial effects of this utility model are as follows: When water flows in from the inlet channel, a buffer component is set to weaken the impact force on the valve core, extending the service life of the valve core. When the valve body is closed, the actuator controls the valve stem to descend, driving the valve core and valve seat to seal and cooperate. A buffer sleeve is set to reduce the collision force between the valve core and valve seat, thereby extending the service life of both. When the valve seat is worn and needs to be replaced, the screw is rotated, and the screw is displaced in the threaded hole and disengaged from the connecting groove to unlock the valve seat. Then, the valve seat is pulled upward to remove it. The boss of the new valve seat is then inserted into the annular groove. The screw is rotated again, and after the screw is displaced in the threaded hole, it extends into the positioning groove to lock the valve seat and complete the installation.

[0022] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0023] See appendix Figure 1-2 The present embodiment of this utility model further includes: an angle regulating valve, comprising an actuator 11, a valve body 12, a valve stem 13, a valve core 14, and a valve seat 15. The valve core 14 is connected to the valve stem 13. The bottom of the valve body 12 is provided with an inlet channel 16 and the side is provided with an outlet channel 17. The inner wall of the valve body 12 is provided with an annular groove 21 corresponding to the lower end position of the valve core 14. The bottom of the valve seat 15 is provided with a boss 151 adapted to the annular groove 21. The side wall of the valve body 12 is provided with a threaded hole 2 penetrating the outer side. The inner end of the threaded hole 2 communicates with the annular groove 21. The boss 151 is provided with a connecting groove 1511 on the side facing the threaded hole 2. A screw 3 is threadedly connected to the threaded hole 2. The inner end of the screw 3 extends into the connecting groove 1511. The outer end of the screw 3 is provided with a vertical rotating rod 31.

[0024] The valve core 14 is fitted with a buffer kit 6 on its side wall and a buffer assembly at its bottom. Specifically, the buffer assembly includes a telescopic tube at the bottom of the valve core 14, a damping spring 51 inside the telescopic tube, and a conical guide 52 at the bottom of the telescopic tube. The buffer kit 6 is preferably made of rubber.

[0025] Furthermore, the inner wall of the valve body 12 connection of the outlet channel 17 is arc-shaped, and a buffer pad 7 is fixedly fixed around the inner wall of the outlet channel 17. When the high-pressure fluid flows directly into the valve body 12 cavity from the inlet channel 16, the arc-shaped surface can guide the fluid and reduce the impact force on the valve body 12. When the high-pressure fluid flows directly into the valve body 12 cavity from the inlet channel 16 and enters the outlet channel 17, the buffer pad 7 reduces the impact force on the valve body 12, thereby extending the service life of the valve body 12.

[0026] The principle of this utility model is as follows: when water flows in from the inlet channel 16, a buffer component is set to weaken its impact on the valve core 14 and extend the service life of the valve core 14; the guide part 52 can disperse the fluid and reduce its impact intensity; the damping spring 51 is compressed under the impact of the fluid, weakening the impact force of the fluid, thereby preventing the valve core 14 from being directly impacted.

[0027] When the valve body 12 is closed, the actuator 11 controls the valve stem 13 to descend, causing the valve core 14 to seal with the valve seat 15. A buffer sleeve is set to reduce the collision force between the valve core 14 and the valve seat 15, thereby extending the service life of both.

[0028] When valve seat 15 is worn and needs to be replaced, rotate screw 3. Screw 3 will displace within threaded hole 2 and disengage from connecting groove 1511, unlocking valve seat 15. Then, pull valve seat 15 upward to remove it. Insert the boss 151 of the new valve seat 15 into annular groove 21. At the same time, positioning block 41 will spring into positioning groove 152 and make a popping sound, thus confirming that the mounting groove is aligned with threaded hole 2, which plays a positioning role and improves installation efficiency. Several positioning blocks 41 can provide radial clamping for the mounting seat, improving the stability of the mounting seat during installation. Then, rotate screw 3 again. Screw 3 will displace within threaded hole 2 and extend into positioning groove 152, locking valve seat 15 and completing the installation.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
