Abstract

This application relates to an anti-scaling ball valve, comprising a valve seat and a valve body. A ball is housed within the valve seat, and the valve body is disposed on both sides of the valve seat. An anti-scaling structure is provided within the valve body. The anti-scaling structure includes a deformable cleaning ring, an abutment portion connected within the cleaning ring, and a sliding plate fixed to the cleaning ring. The sliding plate is installed and movably connected to the valve body. The circumferential sidewall of the cleaning ring abuts against the inner sidewall of the valve body, and the abutment portion extends from the center of the cleaning ring towards its inner sidewall. This application uses a sliding plate to achieve the connection and movement of the cleaning ring within the valve body. The abutment portion supports the cleaning ring, ensuring it is tightly pressed against the inner sidewall of the valve body, reducing contact gaps without affecting the movement of the cleaning ring. When water flows through the valve body, the cleaning ring can slide within the valve body under the force of the water flow, ensuring that the inner sidewall of the valve body is cleaned promptly after each water flow. This solves the problem of easy scaling in ball valves, reduces ball valve clogging, and maintains ball valve performance.

Description

Technical Field

[0001] This application relates to the technical field of ball valves, and in particular to an anti-scaling ball valve. Background Technology

[0002] Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of media. They can be tightly closed with just a 90-degree rotation and a very small torque.

[0003] After long-term use, existing ball valves are prone to scale buildup on the inner wall of the valve body. If this is not treated, it can affect the performance of the ball valve. Regarding the relevant technologies mentioned above, the applicant believes that there is still room for improvement in some current ball valves. Utility Model Content

[0004] To address the problem of scale buildup in ball valves, reduce blockage, and maintain valve performance, this application provides an anti-scaling ball valve.

[0005] The anti-scaling ball valve provided in this application adopts the following technical solution: An anti-scaling ball valve includes a valve seat and a valve body. The valve body is disposed on both sides of the valve seat. An anti-scaling structure is provided in the valve body. The anti-scaling structure includes a deformable cleaning ring, an abutment portion connected to the cleaning ring, and a sliding plate fixed on the cleaning ring. The sliding plate is installed and movably connected to the valve body. The circumferential sidewall of the cleaning ring is attached to the inner sidewall of the valve body. The abutment portion extends from the center of the cleaning ring toward the inner sidewall of the cleaning ring.

[0006] By adopting the above technical solution, a sliding plate is set to realize the connection and movement of the cleaning ring in the valve body. The abutment part can support the cleaning ring so that it fits against the inner wall of the valve body, increasing the contact area without affecting the movement of the cleaning ring. When water flows through the valve body, the cleaning ring can slide in the valve body under the force of water flow, so that the inner wall of the valve body is cleaned in time after each water flow. This solves the problem of easy scaling in ball valves, reduces ball valve blockage, and maintains ball valve performance.

[0007] Preferably, a plurality of deformation grooves are spaced apart on the inner sidewall of the cleaning ring; the abutting part includes an abutting rod and a pressing rod, the abutting rod and the pressing rod are coaxial and extend from the center of the cleaning ring toward the two opposite inner sidewalls of the cleaning ring; the ends of the abutting rod and the pressing rod that are far apart from each other are respectively fixed to corresponding positions on the inner sidewall of the cleaning ring, a rotating rod is rotatably connected to the abutting rod, a mating rod is rotatably connected to the pressing rod, and the rotating rod is inserted into and threadedly connected to the pressing rod.

[0008] By adopting the above technical solution, the coaxial abutting rod and pressure rod abut against both ends of the cleaning ring respectively. The inner diameter of the cleaning ring is adjusted by the threaded engagement of the rotating rod and pressure rod. The setting of the deformation groove enables the cleaning ring to have a higher deformation capacity, thereby making the outer wall of the cleaning ring fit as closely as possible to the inner wall of the valve body, increasing the contact area and achieving a higher cleaning effect.

[0009] Preferably, the valve body has a sliding groove for sliding the sliding plate, and one end of the sliding groove extends through the outward side of the valve body. A sliding rod is fixed on the sliding plate, and the sliding rod is connected to the sliding groove by a connecting spring.

[0010] By adopting the above technical solution, the sliding plate is moved within the valve body under the impact of water flow by utilizing the elastic force of the connecting spring, and is reset by the restoring force after the connecting spring is stretched; it can also play an auxiliary role when cleaning is performed manually.

[0011] Preferably, a rotating block is fixed on both the rotating rod and the mating rod, and a rotating groove is correspondingly opened in the abutting rod and the pressing rod for the rotating block to connect and rotate.

[0012] By adopting the above technical solution, the cooperation between the rotating block and the rotating groove allows the rotating rod to rotate relative to the abutting rod and the cooperating rod to rotate relative to the pressure rod, thereby adjusting the distance between the abutting rod and the pressure rod, and achieving the purpose of the circumferential sidewall of the auxiliary cleaning ring fitting against the inner sidewall of the valve body.

[0013] Preferably, the anti-scaling structure further includes support rods, with several support rods fixed at intervals to the side walls of the abutment rod and the pressure rod, and the ends of the support rods abutting against the inner side wall of the cleaning ring.

[0014] By adopting the above technical solution, the support rod further assists the abutment rod and the pressure rod in abutting the cleaning ring, so that the cleaning ring can fit against the inner wall of the valve body for better cleaning.

[0015] Preferably, the cleaning ring is connected to the valve body via a connecting structure.

[0016] By adopting the above technical solution, the connection structure helps to improve the installation stability of the cleaning ring in the valve body.

[0017] Preferably, the connection structure includes a connecting block and a connecting groove. The connecting block is deformable and is fixed to the outer wall of the cleaning ring and arranged opposite to each other. The upper ends of the opposite connecting blocks extend in a direction away from each other. The connecting groove is opened on the inner wall of the valve body corresponding to the connecting block, and the connecting block is inserted into the corresponding connecting groove.

[0018] By adopting the above technical solution, the inclined connecting block and the connecting groove cooperate to further stabilize the installation of the cleaning ring in the valve body, and the downward-extending connecting groove can reduce water accumulation.

[0019] Preferably, both the end of the rotating rod that passes through the mating rod and the end of the sliding rod are fixed with sealing rings.

[0020] By adopting the above technical solution, the sealing ring improves the sealing effect when the rotating rod and the mating rod rotate, as well as the sealing performance when the sliding rod slides, thereby reducing the erosion of the structure by water flow.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. A sliding plate is installed to enable the connection and movement of the cleaning ring within the valve body. The abutment part supports the cleaning ring, allowing it to fit against the inner wall of the valve body. This increases the contact area without affecting the movement of the cleaning ring. When water flows through the valve body, the cleaning ring can slide within the valve body under the force of the water flow, ensuring that the inner wall of the valve body is cleaned promptly after each water flow. This solves the problem of scale buildup in ball valves, reduces ball valve blockage, and maintains ball valve performance. 2. The coaxial abutting rod and pressure rod abut against both ends of the cleaning ring respectively. The cooperation of the rotating block and the rotating groove allows the rotating rod to rotate relative to the abutting rod and the cooperating rod to rotate relative to the pressure rod. The inner diameter of the cleaning ring is adjusted by the threaded cooperation of the rotating rod and the pressure rod. The setting of the deformation groove gives the cleaning ring a higher deformation capacity, thereby making the outer wall of the cleaning ring fit as closely as possible to the inner wall of the valve body, increasing the contact area and achieving a higher cleaning effect. 3. The support rod further assists the abutment rod and pressure rod in abutting the cleaning ring, allowing the cleaning ring to fit snugly against the inner wall of the valve body for better cleaning.

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] This application discloses an anti-scaling ball valve, as shown in the embodiments below. Figure 1 It includes a valve seat 1 and a valve body 2. The valve body 2 is located on both sides of the valve seat 1. The valve body 2 is provided with an anti-scaling structure 3. The anti-scaling structure 3 includes a deformable cleaning ring 31. The circumferential sidewall of the cleaning ring 31 is attached to the inner sidewall of the valve body 2. The purpose of descaling the valve body 2 is achieved by the reciprocating sliding of the cleaning ring 31 in the valve body 2.

[0026] Reference Figure 1 , 2 The anti-scaling structure 3 also includes a sliding plate 32 fixed to the upper part of the cleaning ring 31. A sliding groove 21 for sliding the sliding plate 32 is provided in the valve body 2, and one end of the sliding groove 21 extends through the outward side of the valve body 2. A sliding rod 321 is fixed on the sliding plate 32. The sliding rod 321 is connected to the sliding groove 21 by a connecting spring 322. The sliding groove 21 extending through one side avoids water accumulation. The elastic force of the connecting spring 322 is used to move the sliding plate 32 within the valve body 2 under the impact of water flow, and it is reset by the restoring force after the connecting spring 322 is stretched. It can also play an auxiliary role when cleaning manually. A sealing ring is fixed to the end of the sliding rod 321 to improve the sealing performance when the sliding rod 321 slides and reduce the erosion of the structure by water flow.

[0027] Reference Figure 1 , 3 The cleaning ring 31 is further connected to the valve body 2 via the connecting structure 4. The connecting structure 4 includes a connecting block 41 and a connecting groove 42. The connecting block 41 is deformable and is fixed to the outer wall of the cleaning ring 31 and is arranged opposite to it. The upper ends of the opposite connecting blocks 41 extend in a direction away from each other. The connecting groove 42 is opened on the inner wall of the valve body 2 corresponding to the connecting block 41. The connecting block 41 is inserted into the corresponding connecting groove 42 by deformation and then reset. The inclined connecting block 41 cooperates with the connecting groove 42, which on the one hand further stabilizes the installation of the cleaning ring 31 in the valve body 2, and on the other hand, the downwardly extending connecting groove 42 can reduce water accumulation.

[0028] Reference Figure 2 , 3 The anti-scaling structure 3 also includes an abutment portion 33, which includes an abutment rod 331 and a pressure rod 332. The abutment rod 331 and the pressure rod 332 are coaxial and extend from the center of the cleaning ring 31 toward the two opposite inner sidewalls of the cleaning ring 31. The ends of the abutment rod 331 and the pressure rod 332 that are far apart from each other are respectively fixed to the corresponding positions on the inner sidewalls of the cleaning ring 31.

[0029] Reference Figure 2 , 3A number of deformation grooves 311 are spaced apart on the inner side wall of the cleaning ring 31; a rotating rod 5 is rotatably connected to one end of the abutment rod 331 near the pressure rod 332, and a mating rod 6 is rotatably connected to one end of the pressure rod 332 near the abutment rod 331. A rotating block 7 is fixed on both the rotating rod 5 and the mating rod 6. Rotating grooves are correspondingly opened in the abutment rod 331 and the pressure rod 332 for the rotating block 7 to connect and rotate, so that the rotating rod 5 can rotate relative to the abutment rod 331 and the mating rod 6 can rotate relative to the pressure rod 332, thereby realizing the adjustment of the distance between the abutment rod 331 and the pressure rod 332.

[0030] Reference Figure 2 , 3 The rotating rod 5 is inserted and threaded into the mating rod 6; a sealing ring is fixed to the end of the rotating rod 5 that passes through the mating rod 6, which improves the sealing effect when the rotating rod 5 and the mating rod 6 rotate, and reduces the erosion of the structure by water flow; the setting of the deformation groove 311 gives the cleaning ring 31 a higher deformation capacity. The inner diameter of the cleaning ring 31 is adjusted by the threaded engagement of the rotating rod 5 and the mating rod 6, thereby making the outer wall of the cleaning ring 31 fit as closely as possible to the inner wall of the valve body 2, increasing the contact area and achieving a higher cleaning effect.

[0031] Reference Figure 2 , 3 The anti-scaling structure 3 also includes support rods 34. Several support rods 34 are fixed at intervals on the side walls of the abutment rod 331 and the pressure rod 332, and the ends of the support rods 34 abut against the inner side wall of the cleaning ring 31. The support rods 34 further assist the abutment rods 331 and the pressure rod 332 in abutting against the cleaning ring 31, so that the cleaning ring 31 can fit against the inner side wall of the valve body 2 for better cleaning.
