Description

Technical Field

[0001] The utility model relates to the field of regulating valves, in particular to a regulating valve component. Background Art

[0002] A regulating valve is a valve used to adjust process parameters such as medium flow, pressure, temperature, liquid level, etc. in the field of industrial automation process control. It automatically adjusts the valve opening according to the control signal in the automation system, thereby achieving the regulation of medium flow, pressure, temperature and liquid level.

[0003] Chinese patent publication number CN217463607U discloses a sealing assembly for a regulating valve, including a valve body and a water inlet pipe, wherein a sealing plate is fixedly connected to the right side of the valve body. The utility model provides an engagement groove so that the sealing ring can be used by the engagement of the sealing block and the engagement groove after installation, thereby reducing the contact gap between the sealing ring and the right side of the inner wall surface of the valve body. Then, by providing a stress ring, the water flow impact force generated when the valve body is opened squeezes the inner wall of the sealing ring. At this time, the sealing ring greatly reduces the contact gap between the sealing ring surface and the right side of the inner wall surface of the valve body due to the squeezing force of the water flow, thereby solving the problem of using a flange to fix the regulating valve and the water inlet pipe, and using the flange for sealing at the same time. Since the flange itself is a hard object, there will be a large gap between the flanges when the user uses the flange for sealing and they cannot fit tightly to each other, causing the problem of water loss. However, although the above patent can increase the sealing performance of the valve body when it is used, there are still some shortcomings when it is used. For example, although the connecting pipe part is extended to the inside of the valve body when it is used, due to the lack of a sealing auxiliary mechanism inside the valve body, the medium flowing inside the valve body is prone to leak in the gap between the sealing ring and the sealing plate. Therefore, those skilled in the art provide a regulating valve assembly to solve the problems raised in the above background technology. Utility Model Content

[0023] The two conduits 15 are fixedly connected to a guide ring 16 on the side away from each other, and the outer surfaces of the two guide rings 16 are respectively fixedly connected to the inner walls of the two connecting pipes 1. The guide ring 16 can be provided to guide the flowing medium to reduce the impact on the conduits 15. The inner wall of the valve body 2 is fixedly connected to two top rings 12, and the side of the two top rings 12 away from each other is respectively fixedly connected to the side of the two first magnetic rings 11 close to each other.
