Description

Technical Field

[0001] This utility model relates to the field of regulating valve technology, and in particular to a switching mechanism for a regulating valve. Background Technology

[0002] Control valves are one of the important control components in industrial pipeline systems, widely used in industries such as petroleum, chemical, power, and water treatment. They are mainly used to control changes in fluid flow, pressure, or temperature to ensure the stability and safety of the production process. The function of a control valve is to change the flow state of the medium by adjusting the valve opening, thereby achieving precise regulation. However, with the continuous improvement of industrial automation, higher requirements are placed on the control accuracy, response speed, stability, and reliability of control valves.

[0003] Traditional control valve switching mechanisms mostly employ mechanical structures, typically consisting of an actuator, valve stem, valve core, and transmission mechanism. In these traditional designs, the valve's switching operation usually relies on a single drive system, such as pneumatic, electric, or hydraulic actuation. While these technologies perform well in some applications, they generally suffer from the following problems:

[0004] Insufficient precision: The drive mechanism and transmission device in traditional control valve systems have certain mechanical clearances and wear problems, resulting in low valve opening control precision. When the valve responds, there may be lag or overshoot, affecting the regulation performance, especially in applications requiring precise control of flow and pressure.

[0005] Poor safety: Traditional actuators usually rely on mechanical locking or other simple fixing devices to ensure the stability of the valve position. However, under complex working conditions, these devices may not be able to fully guarantee the safe fixation of the valve state, leading to valve malfunctions or operational errors during the opening and closing process.

[0006] High maintenance costs: Traditional control valves have a relatively complex mechanical structure and are prone to wear, jamming and other problems, leading to frequent maintenance. In order to maintain the efficient operation of the system, a lot of maintenance work is often required, which increases the operating cost and downtime of the equipment.

[0007] Poor adaptability: Traditional control valve designs may not be able to flexibly adapt to changing operating conditions when facing different environments and control requirements. For example, in some highly corrosive, extreme temperature or high vibration environments, existing control valve structures may have problems such as short service life and unstable performance.

[0008] Therefore, it is essential to invent a switching mechanism for a regulating valve. Utility Model Content

[0009] To address the aforementioned technical problems, this utility model provides a switching mechanism for a control valve, solving the issues of insufficient accuracy, poor safety, high maintenance costs, and poor adaptability inherent in existing control valves. The switching mechanism for a control valve includes an actuator housing, a switch control seat, a tension display seat, a valve stem, and an actuation drive structure. The switch control seat is slidably mounted below the actuator housing, and the tension display seat is slidably mounted above the actuator housing. The valve stem is fixedly mounted at the bottom of the switch control seat and connected to the valve core. The actuation drive structure is fixedly mounted on both sides of the actuator housing.

[0010] The actuator housing includes a base plate, side protective shells, extension slide tubes, mounting plate, and titanium wire locks. The side protective shells are fixedly installed on the outside of the base plate, and the extension slide tubes are fixedly installed on the top, bottom, and sides of the base plate. The mounting plate is fixedly installed on the surface of the base plate, and the titanium wire locks are fixedly installed on the surface of the mounting plate.

[0011] The actuator drive structure includes an actuator slide, a drive push rod, a connecting seat, a push arm, and a fixing latch. The actuator slide is slidably installed inside the extension slide tubes on both sides of the actuator housing. One end of the drive push rod is fixedly installed on the outer end of the actuator slide. The other end of the drive push rod is fixedly installed at the top end inside the extension slide tubes on both sides of the actuator housing. The connecting seat is fixedly installed on the inner end of the actuator slide. One end of the push arm is rotatably installed on the inner end of the connecting seat. The other end of the push arm is rotatably installed on the switch control seat and the tension display seat, respectively. The fixing latch is fixedly installed on the inner end of the connecting seat.

[0012] The actuator housing has a cross-shaped structure, and the extension slide tube consists of four metal pipes. The interior of this extension slide tube allows for the sliding of the switch control seat, tension display seat, and two sets of actuator drive structures. The titanium wire lock uses a set of titanium wire locks, with lock holes on all four outer surfaces. These locks serve the following functions: ① Support and protection: As the external structure of the entire switching mechanism, the actuator housing provides a robust support frame, ensuring that all internal components operate in the correct position and a stable environment. Through its overall design, the housing also protects internal components from external environmental influences such as dust, moisture, or mechanical damage. ② Transmission and distribution of driving force: The actuator housing, through its design, supports the actuator drive structures, namely the actuator slide and drive push rod, and transmits power from the drive source to the internal actuator components. ③ Locking function: Regardless of whether the valve is open or closed, the titanium wire lock effectively locks the position of the actuator slide or connecting seat, preventing unnecessary movement due to external interference or internal vibration.

[0013] The actuator slide inside the actuator drive structure can reciprocate within the extended slide tube via the operation of the drive push rod. When the actuator slide slides towards the center of the actuator housing, it can push the switch control seat and tension display seat away from the center of the actuator housing via the push arm. When the actuator slide is close to the center of the actuator housing, the locking buckle at the front end of the connecting seat can engage with the titanium wire lock. This has the following functions: ① Providing power and driving motion: The actuator drive structure receives power from the drive push rod and converts it into movement of the actuator slide and other related components. Through this conversion, the actuator drive structure can drive the valve stem and valve core to perform corresponding operations. ① To control the opening and closing of the valve; ② To link multiple components: The actuator not only drives the actuator slide, but also coordinates with multiple components to ensure that the opening and closing process of the entire regulating valve is coordinated and consistent. For example, the actuator acts on the switch control seat and the tension display seat through the push arm to realize the opening or closing of the valve, and at the same time realizes the physical display of the tension, ensuring that the opening and closing of the valve and the display of the tension are synchronized; ③ To simplify the system: The actuator can also be used with safety devices such as titanium wire locks to provide necessary locking during the movement of the actuator slide or other components, to prevent misoperation caused by system vibration or external interference, and to ensure that the system always operates stably according to the predetermined trajectory.

[0014] A connecting plate is fixedly installed on the extended slide tube at the bottom of the actuator housing, and the actuator housing is fixedly installed on the valve body through the connecting plate at its bottom; a stabilizing sleeve is fixedly installed inside the extended slide tube at the bottom of the actuator housing, and a valve stem is slidably installed inside the stabilizing sleeve.
