[0030] like Figures 1 to 4 As shown, a double-sided display structure of a regulating valve includes:
[0031] The valve body 1 has a transverse channel 11 and a longitudinal channel 12 provided therein. The transverse channel 11 passes through both ends of the valve body 1, and the longitudinal channel 12 passes through the top of the valve body 1. A valve stem 13 is provided in the longitudinal channel 12. One end of the valve stem 13 extends out of the top of the valve body 1 and moves vertically in the longitudinal channel 12. A valve cylinder 14 is provided in the transverse channel 11. The valve cylinder 14 moves horizontally to control the on / off of the working medium in the transverse channel 11.
[0032] Among them, a guide rod 15 is provided inside the valve cylinder 14, and the guide rod 15 is connected to the bottom end of the valve stem 13. When the valve stem 13 moves upward, the guide rod 15 drives the valve cylinder 14 to move rightward;
[0033] The support base 2 is provided with two symmetrical opening indicator plates on the outside and a trapezoidal screw 22 on the inside;
[0034] One end of the trapezoidal screw 22 extends out of the top of the support seat 2, and the other end is connected to the top of the valve stem 13; a slider pointer 25 is provided on the opening indicator plate, and one side of the slider pointer 25 is fixedly set on the side of the trapezoidal screw 22;
[0035] The valve stem 13 pushes the trapezoidal screw 22 to move in the vertical direction, and the trapezoidal screw 22 drives the slider pointer 25 to move accordingly in the vertical direction.
[0036] A transverse channel 11 and a longitudinal channel 12 are provided inside the valve body 1. A valve stem 13 is provided in the longitudinal channel 12. The top end of the valve stem 13 extends to the outside of the valve body 1 and can move vertically in the longitudinal channel 12. The bottom of the valve stem 13 is connected to the valve cylinder 14 located in the transverse channel 11. When the valve stem 13 moves upward, the connected guide rod 15 also drives the valve cylinder 14 to move horizontally to the right to realize the circulation or cutoff of the working medium; the support seat 2 is provided with two front-to-back symmetrical opening indicator plates, and the internal structure includes a trapezoidal screw 22, one end of the trapezoidal screw 22 is connected to the top of the support seat 2, and the other end is connected to the top of the valve stem 13. The slider pointer 25 on the opening indicator plate is fixed to the side of the trapezoidal screw 22. When the valve stem 13 pushes the trapezoidal screw 22 to move in the vertical direction, the slider pointer 25 will also move accordingly in the vertical direction to display the current valve position status.
[0037] Through internal mechanical connections and movement, the circulation of the working medium is precisely controlled, ensuring the operational accuracy and reliability of the regulating valve; the double-sided opening indicator plate provides the possibility of observation from both sides of the valve body 1, greatly improving the convenience of operation; the movement of the slider pointer 25 along the trapezoidal screw 22 can accurately reflect the actual position of the valve stem 13, thereby accurately displaying the opening and closing status of the valve in real time, which not only enhances the functionality of the regulating valve, but also improves its overall working performance.
[0038] In this embodiment, a plurality of ball bearings 23 are provided at the contact point between the slider pointer 25 and the trapezoidal screw 22 , and the trapezoidal screw 22 moves in the vertical direction to drive the ball bearings 23 .
[0039] Several ball bearings 23 are configured at the contact point between the slider pointer 25 and the trapezoidal screw 22. The setting of the ball bearings 23 allows the trapezoidal screw 22 to smoothly drive the ball bearings 23 when moving in the vertical direction, thereby ensuring the smooth movement of the slider pointer 25, greatly reducing the friction and resistance that the slider pointer 25 may encounter during the movement, and improving the continuity and accuracy of the movement. Moreover, since the ball bearings 23 can effectively disperse and withstand the pressure generated during the movement, it not only extends the service life of the trapezoidal screw 22 and the slider pointer 25, but also ensures the long-term stability and reliability of the indication system. The smooth movement of the ball bearings 23 also ensures the accuracy of the opening indication.
[0040] In this embodiment, scale lines 211 are provided on both opening indicator plates, and the scale lines 211 are used to provide valve position readings.
[0041] The scale line 211 enables the operator to read the precise value of the valve position directly from the opening indicator plate, providing a quick and intuitive method to judge and adjust the open and closed state of the valve. Through the accurate valve position reading, the operator can better control the working medium flowing through the valve body 1 and ensure the efficient operation of the working system.
[0042] In this embodiment, a plurality of ball bearings 23 are fixed with shaft retaining rings 24 to prevent them from falling off.
[0043] By installing a ball bearing 23 fixing ring between the trapezoidal screw 22 and the slider pointer 25, it is ensured that the ball bearing 23 will not fall off or shift even during long-term operation or in a vibrating environment, reducing mechanical failures caused by component shedding, avoiding potential operational interruptions and maintenance needs, thereby improving overall stability and ease of maintenance. Maintaining the stable fixation of the ball bearing 23 also ensures that the movement of the slider pointer 25 along the trapezoidal screw 22 is smoother and more precise, enhancing the accuracy of the opening indication, and enabling the operator to more effectively monitor and control the status of the regulating valve.
[0044] In this embodiment, a plurality of sealing rings 3 are provided at the contact parts of the valve body 1 and each component, and the sealing rings 3 are used to prevent leakage of the working medium.
[0045] The contact parts of the valve body 1 and its internal components are equipped with several sealing rings 3. The main function of the sealing ring 3 is to prevent the leakage of the working medium, effectively maintain the closedness of the control valve, and ensure that the working medium such as gas or liquid will not escape when flowing in the transverse channel 11 and the longitudinal channel 12 in the valve body 1. The use of the sealing ring 3 improves the operational safety of the control valve, avoids potential environmental pollution and waste of resources, and also protects the staff from possible harm from dangerous media. By maintaining the sealing performance, the sealing ring 3 also helps to maintain the pressure stability of the system, thereby improving the control accuracy and efficiency of the control valve.
[0046] In this embodiment, the opening indicator plate is made of a high-temperature-resistant and corrosion-resistant alloy material.
[0047] The opening indicator plate is made of high-temperature resistant and corrosion-resistant alloy material. The selection of alloy material significantly improves the performance and durability of the control valve in harsh environments. The high-temperature resistance ensures that the opening indicator plate will not be deformed or damaged under high-temperature working conditions, maintaining its structural integrity and normal function; the corrosion resistance enables the opening indicator plate to resist the erosion of chemical media, avoiding material degradation and performance reduction caused by corrosion, which not only extends the service life of the opening indicator plate, but also ensures that the accuracy of the valve position reading will not be affected by the deterioration of environmental conditions.
[0048] In this embodiment, anti-skid patterns 221 are provided on the side surface of the trapezoidal screw 22 , and the anti-skid patterns 221 are used to enhance the friction force when the slider pointer 25 is moved.
[0049] The anti-slip grooves 221 help the slider pointer 25 move more stably on the trapezoidal screw 22 by providing additional surface roughness, avoiding sliding or jumping that may occur due to insufficient friction during operation. The increased friction makes the movement of the slider pointer 25 smoother and more precise, thereby directly improving the accuracy and reliability of the opening indication. The anti-slip grooves 221 on the trapezoidal screw 22 not only simply improve the interaction between components, but also play an important role in ensuring the accuracy and long-term stability of the entire control valve operation.
[0050] In this embodiment, a protective cover 4 is provided on the top of the valve body 1 . A through hole 41 is provided on the protective cover 4 . The valve stem 13 passes through the through hole 41 to move in the vertical direction.
[0051] A protective cover 4 is mounted on the top of the valve body 1. A through-hole 41 in the protective cover 4 allows the valve stem 13 to pass through and move vertically. The protective cover 4 provides an additional layer of protection, preventing external debris and contaminants from entering the interior of the valve body 1. At the same time, the protective cover 4 helps reduce direct contact between the interior of the valve body 1 and the external environment, thereby reducing the impact of environmental factors such as dust, water, and other corrosive substances on the valve stem 13 and other internal components. The through-hole 41 in the protective cover 4 ensures that the valve stem 13 can move freely without any physical obstruction, maintaining the flexibility and responsiveness of the control valve's operation, effectively enhancing the overall durability and reliability of the control valve, and ensuring its stability and long-term performance under various operating conditions.
