Description

Technical Field

[0001] This application relates to the field of valve core technology, specifically a novel regulating valve core opening structure. Background Technology

[0002] Regulating valves can regulate flow by changing the flow cross-sectional area through rotating the valve core.

[0003] Existing regulating valves have a V-shaped opening. When the valve core rotates, the V-shaped opening and the inner wall of the valve body squeeze against each other, which can prevent some particles from clogging the valve body through cutting force. However, when the range of valve core rotation is small, the particles stuck between the valve core opening and the inner wall of the valve body will affect the valve core's closing. At the same time, with continuous rotation of the valve core, the opening of the valve core and the inner wall of the valve body are two corners that clamp the particles. As the valve core rotates, the particles will create extrusion indentations on the valve core opening and the inner wall of the valve body, causing damage to the valve body.

[0004] Therefore, this application provides a novel regulating valve core opening structure to solve the above problems. Utility Model Content

[0005] This application provides a novel regulating valve core opening structure, which aims to solve the problems mentioned in the background art, such as the fact that when the rotation range of the existing valve core is small, particles stuck between the valve core opening and the inner wall of the valve body will affect the closure of the valve core, and continuous rotation of the valve core will cause extrusion indentations on the valve core opening and the inner wall of the valve body, thus damaging the valve body.

[0006] To achieve the above objectives, this application provides the following technical solution: a novel regulating valve core opening structure, applied to a ball valve, wherein the front of the ball valve has a V-shaped opening for regulating flow.

[0007] To facilitate particle movement: Symmetrical particle sliding removal components are provided on both sides of the inner wall of the V-shaped opening. Each removal component includes a central slider located in the middle of the side of the V-shaped opening and end sliders symmetrically located at the top and bottom of the central slider for engaging with it. When the ball valve is rotated, particles stuck between the V-shaped opening and the inner wall of the valve body will be gripped by the central slider or end slider, moving along the arcuate surface of the central slider or end slider. This allows the particles to slide between the V-shaped opening and the inner wall of the valve body, preventing them from being squeezed and damaged by the rotation of the ball valve. After prolonged use, scratches may appear on the central slider and end sliders. To prevent particles from getting stuck between these scratches, the central slider and end sliders need to be replaced. This can be done by removing the fixing bolts, moving the limiting block and connecting block out of the mounting slot, and replacing the central slider or end slider.

[0008] Preferably, to prevent movement of the middle slider and the end slider: a limiting block for mounting the middle slider and the end slider is provided on the side of the middle slider and the end slider facing the inner wall of the V-shaped opening, and a connecting block for connecting the limiting block and the middle slider or the end slider is fixedly connected to the side of the limiting block facing the middle slider or the end slider. By inserting the limiting block and the connecting block inside the mounting groove, the middle slider and the end slider are installed with the ball valve, preventing the middle slider and the end slider from shaking.

[0009] Preferably, the inner wall of the V-shaped opening is provided with a mounting groove for sliding insertion of the limiting block and the connecting block.

[0010] Preferably, to facilitate the movement of particles, the cross-sections of the middle slider and the end slider are semi-circular. The arc shape of the middle slider or the end slider, acting in conjunction with the inner wall of the valve body, guides the movement of particles, preventing them from being trapped and causing damage to the valve body and the V-shaped opening.

[0011] Preferably, for securing the limiting block: a fixing bolt for fixing the limiting block and the V-shaped opening is provided on one side of the limiting block; a mounting hole for the fixing bolt to pass through is provided on one side of the limiting block; a threaded hole is provided on one side of the inner wall of the mounting groove; the fixing bolt is inserted into the mounting hole and threadedly connected to the threaded hole. By simultaneously inserting the fixing bolt into the mounting hole and the threaded hole, the limiting block is fixed inside the mounting groove.

[0012] Preferably, to reduce corrosion of the fixing bolt threads: a sealing gasket is fitted over the fixing bolt to seal between the fixing bolt and the mounting hole. When the fixing bolt is installed in the mounting hole, the sealing gasket is compressed, preventing corrosion of the portion of the fixing bolt inserted into the threaded hole, thereby facilitating the removal of the fixing bolt.

[0013] Preferably, to reduce water inflow into the threaded hole: a sealing strip is fixedly connected to the outer walls of the limiting block and the connecting block for sealing between the limiting block and the mounting groove. By fixing the sealing strip to the outer walls of the limiting block and the connecting block, the sealing strip seals the gap between the mounting groove and the limiting block and the connecting block, preventing water from flowing into the threaded hole from the mounting groove.

[0014] This application utilizes a design incorporating a V-shaped opening, a removal component, a limiting block, and a fixing bolt. When the ball valve is rotated, particles stuck between the V-shaped opening and the inner wall of the valve body are gripped by the central or end slider, which engages with the inner wall of the valve body. The particles move along the arc-shaped surface of the central or end slider, allowing them to slide out from between the V-shaped opening and the inner wall of the valve body. This prevents the particles from being squeezed and damaged by the ball valve during rotation, thus avoiding the need to replace the central or end slider. In this case, the fixing bolt can be removed, and the limiting block and connecting block can be moved out of the mounting slot for replacement of the central or end slider.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] This embodiment provides a novel regulating valve core opening structure, such as... Figure 1-7 As shown, this opening structure is applied to ball valve 1, and a V-shaped opening 2 for adjusting the flow rate is provided on the front of ball valve 1.

[0026] To facilitate the movement of particles: On both sides of the inner wall of the V-shaped opening 2, there are symmetrically arranged removal components 3 for the sliding of particles. The removal components 3 include a central slider 31 disposed in the middle of the side of the V-shaped opening 2 and end sliders 32 symmetrically disposed at the top and bottom of the central slider 31 for cooperating with the central slider 31. When the ball valve 1 is rotated, particles stuck in the V-shaped opening 2 and the inner wall of the valve body will cause the middle slider 31 or the end slider 32 to cooperate with the inner wall of the valve body to clamp the particles. The particles will move along the arc surface of the middle slider 31 or the end slider 32, so that the particles will slide out between the V-shaped opening 2 and the inner wall of the valve body. This prevents the particles from being squeezed and damaged by the ball valve 1 as it rotates. After long-term use, scratches will appear on the middle slider 31 and the end slider 32. To prevent particles from getting stuck between the scratches, the middle slider 31 and the end slider 32 need to be replaced. This can be done by removing the fixing bolt 7, moving the limiting block 4 and the connecting block 5 out of the mounting slot 6, and replacing the middle slider 31 or the end slider 32.

[0027] Furthermore, the ball valve 1 is the valve core of an existing regulating valve, and the V-shaped opening 2 is a V-shaped opening. Thus, by rotating the ball valve 1, the flow rate is controlled by the area of ​​the flow through the V-shaped opening 2, which is a current technology in the existing field.

[0028] Specifically, to prevent the movement of the middle slider 31 and the end slider 32: a limiting block 4 for mounting the middle slider 31 and the end slider 32 is provided on the side of the middle slider 31 and the end slider 32 facing the inner wall of the V-shaped opening 2. A connecting block 5 for connecting the limiting block 4 and the middle slider 31 or the end slider 32 is fixedly connected to the side of the limiting block 4 facing the middle slider 31 or the end slider 32. The inner wall of the V-shaped opening 2 has a mounting groove 6 for sliding the limiting block 4 and the connecting block 5. By inserting the limiting block 4 and the connecting block 5 into the mounting groove 6, the middle slider 31 and the end slider 32 are installed with the ball valve 1, preventing the middle slider 31 and the end slider 32 from shaking. Two removal components 3 are symmetrically arranged. The outer edge of the removal component 3 is flush with the outer edge of the V-shaped opening 2. The top and bottom ends of the middle slider 31 are symmetrically arranged with end sliders 32. The contact parts of the middle slider 31 and the end sliders 32 are flush. The end of the end slider 32 away from the middle slider 31 is an arc end. A limiting block 4 and a connecting block 5 are arranged on the side of the middle slider 31 facing the ball valve 1. A limiting block 4 and a connecting block 5 are respectively arranged at both ends of the end slider 32 facing the ball valve 1. The connecting block 5 is fixed by welding to the part of the limiting block 4 and the middle slider 31 or the end slider 32. The limiting block 4 and the connecting block 5 form a transverse T-shape. The size of the mounting groove 6 is adapted to the total size of the limiting block 4 and the connecting block 5. The shape of the mounting groove 6 corresponds to the total shape of the limiting block 4 and the connecting block 5.

[0029] Specifically, to facilitate the movement of particles, the cross-sections of the middle slider 31 and the end slider 32 are semi-circular. The arc shape of the middle slider 31 or the end slider 32, acting in conjunction with the inner wall of the valve body, guides the movement of particles, preventing them from being trapped and causing damage to the valve body and the V-shaped opening 2.

[0030] Specifically, to secure the limiting block 4: a fixing bolt 7 is provided on one side of the limiting block 4 for fixing the limiting block 4 and the V-shaped opening 2; a mounting hole for the fixing bolt 7 to pass through is provided on one side of the limiting block 4; a threaded hole is provided on one side of the inner wall of the mounting groove 6; the fixing bolt 7 is inserted into the mounting hole, and the fixing bolt 7 is threadedly connected to the threaded hole. By simultaneously inserting the fixing bolt 7 into the mounting hole and the threaded hole, the limiting block 4 is fixed inside the mounting groove 6. The size of the mounting hole is adapted to the outer diameter of the fixing bolt 7, and the inner thread of the threaded hole meshes with the outer thread of the fixing bolt 7.

[0031] More specifically, to reduce corrosion of the threads of the fixing bolt 7, a sealing gasket 8 is fitted over the fixing bolt 7 to seal between the fixing bolt 7 and the mounting hole. By installing the fixing bolt 7 inside the mounting hole, the sealing gasket 8 is compressed, preventing corrosion of the portion of the fixing bolt 7 inserted into the threaded hole, thus facilitating the removal of the fixing bolt 7. The sealing gasket 8 is a ring-shaped rubber ring; through the installation of the fixing bolt 7, the sealing gasket 8 is continuously compressed, blocking the gap between the fixing bolt 7 and the mounting hole, reducing the inflow of water into the threaded hole.

[0032] More specifically, to reduce water inflow into the threaded hole: a sealing strip 9 is fixedly connected to the outer walls of the limiting block 4 and the connecting block 5 to seal the space between the limiting block 4 and the mounting groove 6. By fixing the sealing strip 9 to the outer walls of the limiting block 4 and the connecting block 5, the sealing strip 9 seals the gap between the mounting groove 6 and the limiting block 4 and the connecting block 5, preventing water from flowing into the threaded hole from the mounting groove 6. The sealing strip 9 is a rubber strip, adhered to the outer walls of the limiting block 4 and the connecting block 5. When the limiting block 4 and the connecting block 5 are placed inside the mounting groove 6, the sealing strip 9 is compressed, thereby filling the gap between the limiting block 4 and the connecting block 5 and the mounting groove 6, thus preventing water from flowing into the threaded hole through the mounting groove 6 and reducing corrosion at the connection between the fixing bolt 7 and the threaded hole.

[0033] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
