[0032] Specifically, the outer wall of the pipeline 1 is fixedly connected with the valve body 3 through welding, realizing effective control and management of the fluid, ensuring the close connection between the pipeline 1 and the valve body 3, and creating good flow conditions for the fluid, ensuring smooth operation of the entire conveying link. The top of the valve body 3 is provided with a valve cover 4 which tightly covers the valve body 3, providing the valve body 3 with all-round sealing protection, effectively preventing the intrusion of dust, debris and impurities from the outside, avoiding the entry of these impurities into the valve body 3, thereby ensuring that the valve body 3 can always be in a normal and stable working state, to some extent, enhancing the structural strength of the valve body 3 and prolonging its service life. The top of the valve cover 4 is uniformly distributed with a plurality of screws 5 made of high-strength material, which are tightly connected with the valve cover 4 and the valve body 3 in a threaded connection manner. The bottom end of the screw 5 penetrates the valve cover 4 and is screwed into the pre-designed threaded hole of the valve body 3, forming a stable and reliable connection structure. The threaded connection manner not only facilitates installation and removal, but also enables the valve cover 4 to be tightly attached to the valve body 3 through precise tightening operation, enhancing the stability of the connection between the two, ensuring that the valve cover 4 will not loosen or displace under various complex working conditions. The internal core component of the valve body 3 is a ball 6, which is the key to controlling the fluid on-off of the valve body 3. When the through hole of the ball 6 is in the same straight line with the flow passage of the pipeline 1 and the valve body 3, the fluid can flow smoothly without any obstruction, realizing the on state. When the ball 6 is rotated to make its through hole perpendicular to the flow passage, the fluid passage is blocked, thereby realizing precise and effective control of the fluid flow, meeting the needs of different production processes. The top of the ball 6 is fixedly connected with a valve stem 7 through mechanical processing, providing a necessary operation interface for the rotation of the ball 6. The outer side of the top of the valve stem 7 is further fixedly connected with a rocker 8, which greatly reduces the torque required by the operator when rotating the valve stem 7. With the help of the rocker 8, the operator can easily rotate the valve stem 7, realizing precise control of the ball 6, and significantly improving the convenience and efficiency of the operation. Inside the front side of the pipeline 1, a flexible sliding piston 9 is arranged. The middle part of the piston 9 is a hollow structure, which is precisely adapted to the inner wall of the pipeline 1, enabling smooth forward and backward sliding in the pipeline 1 and ensuring tight adhesion to the inner wall of the pipeline 1, without fluid leakage. During the long-term operation of the pipeline 1, various impurities will inevitably adhere to the inner wall, which not only affects the conveying efficiency of the pipeline 1, but also damages the subsequent equipment. The piston 9 can slide forward and backward in the pipeline 1 to thoroughly clean the impurities on the inner wall of the pipeline 1, effectively maintaining the cleanliness and smoothness of the pipeline 1, and ensuring the stability and efficiency of fluid conveying. The front side of the piston 9 is fixedly connected with a pull rod 10, and the operator can control the sliding position and speed of the piston 9 by holding the pull rod 10, realizing precise control of the working state of the piston 9 and ensuring that the impurities on the inner wall of the pipeline 1 are cleaned in a timely and effective manner. In order to further improve the impurity treatment function of the pipeline 1, a box body 11 is fixedly connected to the outer side of the bottom of the pipeline 1.The box 11 is responsible for collecting various impurities generated in the pipeline 1 and accumulated liquid. During the impurity cleaning process of the piston 9 on the inner wall of the pipeline 1, the removed impurities naturally settle and flow into the box 11, realizing the centralized collection and management of these substances, avoiding the random accumulation of impurities and liquid in the pipeline 1. The bottom of the box 11 is designed with a threaded plug 12. The threaded plug 12 is tightly matched with the bottom of the box 11 through a threaded connection mode. When it is necessary to discharge and treat the impurities or liquid collected in the box 11, the operator only needs to unscrew the threaded plug 12 to open the discharge channel of the box 11, quickly and conveniently discharging the substances therein, completing the cleaning work. After the cleaning work is completed, the threaded plug 12 is tightened again to ensure the sealing of the box 11 and prepare for the next impurity collection work. The filter mechanism 2 is arranged on the outer side of the front end of the pipeline 1. The filter mechanism 2 is responsible for filtering impurities in the fluid flowing in the pipeline 1.

[0033] With reference to Figure 2 and Figure 5 The filter mechanism 2 includes a filter barrel 201. The inside of the filter barrel 201 is fixedly connected to the outer wall of the pipeline 1. The filter mechanism 2 is tightly combined with the pipeline 1 to ensure the filtering effect. The top of the filter barrel 201 is fixedly connected with a support plate 202. The support plate 202 can provide support for the components above. The left side of the support plate 202 is fixedly connected with a hinge 203. The hinge 203 can make the cover 204 flexibly rotate, facilitating opening and closing. The right side top of the hinge 203 is fixedly connected with a cover 204. The cover 204 can protect the inside of the filter mechanism 2, preventing foreign matter from entering. The bottom of the cover 204 is fixedly connected with a rubber pad 205. The rubber pad 205 can enhance the sealing between the cover 204 and the filter barrel 201, preventing fluid leakage. The inside of the filter barrel 201 is provided with a filter screen 206. The filter screen 206 can filter the fluid in the pipeline 1, removing impurities therein.

[0034] Specifically, the core component of the filtering mechanism 2 is the filtering barrel 201, which is fixedly connected to the front side of the outer wall of the pipeline 1, ensuring seamless connection between the filtering barrel 201 and the pipeline 1. When the fluid flows from the pipeline 1 through this place, it can smoothly enter the inside of the filtering barrel 201 to receive fine filtering treatment, greatly guaranteeing the reliability and continuity of the filtering work. On the top of the filtering barrel 201, there is a sturdy support plate 202 made of high-strength metal material, which perfectly fits the top of the filtering barrel 201 and is fixed on the filtering barrel 201 by welding process, providing stable support for various components above and ensuring that the entire filtering mechanism 2 will not be displaced or shaken due to external forces or vibrations during operation, thereby ensuring the normal operation of the filtering mechanism 2 and the stability of the filtering effect. On the left edge of the support plate 202, there is a hinge 203 with excellent flexibility and durability, which is fixed at a specific position on the support plate 202 and is the key pivot connecting the support plate 202 and the cover 204. With the help of the hinge 203, the cover 204 can be opened and closed. During daily maintenance or cleaning of the inside of the filtering mechanism 2, the operator can easily rotate the cover 204 around the hinge 203 to open it. The right top of the hinge 203 is stably connected with the cover 204, and the cover 204 can completely cover the top opening of the filtering barrel 201, effectively blocking the invasion of dust, debris, foreign matter and impurities from the outside, avoiding the interference of impurities with the normal operation of the filtering mechanism 2, ensuring that the inside of the filtering barrel 201 always maintains a clean and pure working environment, thereby prolonging the service life of the filtering mechanism 2 and ensuring the stability and reliability of the filtering effect. On the bottom of the cover 204, a layer of rubber pad 205 is fixedly connected, which has good sealing performance and effectively prevents the fluid from leaking out from the connection between the cover 204 and the filtering barrel 201 during the filtering process, avoiding resource waste and environmental pollution, improving filtering efficiency and filtering quality. Inside the core position of the filtering barrel 201, there is a filter screen 206, which can accurately intercept various sizes of impurity particles in the fluid. When the fluid flows through the filter screen 206, the impurities will be effectively blocked on the surface of the filter screen, while the pure fluid can smoothly pass through the mesh of the filter screen and continue to flow along the pipeline 1, providing efficient and reliable impurity filtering service for the fluid in the pipeline 1, improving the purity of the entire fluid and guaranteeing the normal operation of the subsequent equipment.

[0035] Referring to Figure 1 and Figure 2The top right side of the cover 204 is fixedly connected with a handle 13, which facilitates the user to open and close the cover 204, and the operation is more labor-saving. The outer wall of the handle 13 is fixedly connected with a rubber sleeve 14, which can increase the comfort and friction of holding, prevent the hands from slipping, the top of the filter barrel 201 is fixedly connected with two fixed rods 15, the two fixed rods 15 can connect the handle 16 with the filter barrel 201, which is convenient for operating the filter barrel 201, the top of the two fixed rods 15 is fixedly connected with the same handle 16, the filter screen 206 can be conveniently taken out from the filter barrel 201 for cleaning or replacement, the outer wall of the pipeline 1 is fixedly connected with a fixed block 17 at the right end of the back side, the fixed block 17 can provide fixed support for the pressure gauge 18, so that it is more stable to install, the right side of the fixed block 17 is rotatably connected with the pressure gauge 18, the pressure gauge 18 can display the pressure in the pipeline 1 in real time, which is convenient for the user to understand the working state of the pipeline 1;

[0036] Specifically, in the filter mechanism 2, the top right side of the cover 204 is fixedly connected with the handle 13, the handle 13 is made of a solid and durable metal with light texture, which ensures that the user can provide a powerful grip point while not adding too much weight to the cover 204, so that the user can complete the operation with minimal effort when opening or closing the cover 204, improving the convenience and labor-saving degree of operation. On the outer wall of the handle 13, a layer of carefully made rubber sleeve 14 is tightly attached, which has excellent flexibility, wear resistance and anti-skid performance, and the surface is also designed with unique texture. The texture not only increases the friction between the rubber sleeve 14 and the skin of the hand, making the grip more stable, effectively preventing slipping caused by sweating or uneven force during operation, ensuring that the user can always hold the handle 13 firmly. On the top of the filter barrel 201, two solid fixed rods 15 are symmetrically fixedly connected, which have excellent compression and tension resistance and can maintain stable structural strength in various complex working environments. The top of the two fixed rods 15 is fixedly connected with the same handle 16, which is made of the same material as the fixed rod 15, ensuring sufficient strength and good toughness. When cleaning or replacing the filter screen 206, the user only needs to easily hold the handle 16 and apply upward force to smoothly and conveniently remove the filter screen 206 from the filter barrel 201, reducing the time and labor cost required for maintenance and improving work efficiency. On the outer wall of the pipeline 1, a fixed block 17 is fixedly connected to the right end of the rear side, which is made of high-strength alloy material and is firmly attached to the pipeline 1 through a welding connection, providing a reliable fixed support point for the pressure gauge 18. The fixed block 17 has a precise mounting hole position to ensure that the pressure gauge 18 can be easily aligned and fixed during installation without installation deviation or loosening. The right side of the fixed block 17 is flexibly connected with the pressure gauge 18 through a rotating connection mechanism, which can ensure smooth rotation of the pressure gauge 18 and has good stability and reliability. The pressure gauge 18 can display the pressure in the pipeline 1 in real time and accurately, presenting the pressure value in the pipeline 1 to the user in an intuitive way. When pressure fluctuations or abnormal conditions occur, the user can observe the reading of the pressure gauge 18 to timely understand the working status of the pipeline 1 and take corresponding measures for adjustment or maintenance. Through the real-time pressure data provided by the pressure gauge 18, the user can effectively manage and maintain the entire valve to ensure its safe, stable and efficient operation.

[0037] Referring to Figure 3 and Figure 4The top of the valve cover 4 is fixedly connected with a protective shell 19, which can protect the components on the top of the valve cover 4 from being collided or damaged by the outside world. The top of the protective shell 19 is fixedly connected with a limiting block 20 on both sides, which can limit the opening and closing of the valve to prevent displacement. The inner rear side of the pipeline 1 is fixedly connected with a shock pad 21, which can reduce the impact force generated by the fluid flowing in the pipeline 1, reduce noise, and protect the pipeline 1. The inner side of the pipeline 1 is fixedly connected with a sealing ring 22 in the middle, which can enhance the sealing performance of the pipeline 1 to prevent fluid leakage. The front side of the sealing ring 22 is fixedly connected with a flow guide block 23, which can guide the flow direction of the fluid in the pipeline 1, making the fluid flow more smoothly. The bottom of the box body 11 is fixedly connected with a gasket 24, which can reduce the gap between the threaded plug 12 and the box body 11.

[0038] Specifically, the top of the valve cover 4 is fixedly connected with the protective shell 19, which is made of a solid and durable metal material and can effectively resist external impact to prevent the valve stem 7 from being damaged due to collision. The top of the protective shell 19 is fixedly connected with a limiting block 20 on each side. The limiting block 20 has a certain toughness. During the operation of the valve, when the rocker 8 is rotated to a certain angle, that is, the valve is opened or closed to a predetermined position, the limiting block 20 can contact the rocker 8 to prevent it from continuing to rotate, thereby accurately limiting the opening and closing of the valve. This effectively avoids the problem of the rocker 8 rotating beyond the reasonable range due to excessive force or misoperation of the operator, which may cause the ball 6 to shift and the valve seat seal to be damaged. This ensures that the valve can always be operated within a safe and effective angle range, ensuring the normal service life and fluid control function of the valve. The inside rear side of the pipeline 1 is fixedly connected with a shock pad 21. The shock pad 21 is made of special rubber material and has excellent elasticity and damping characteristics. It is uniformly coated with strong glue and tightly attached to the inside rear side of the pipeline 1. During the operation of the pipeline 1, the fluid flows at a certain speed and pressure in the pipe, which may generate a large impact force on the valve. The shock pad 21 can absorb the energy of the fluid impact and convert it into its own elastic potential energy, thereby reducing the impact force of the fluid on the valve. This not only reduces the noise generated by the impact and avoids the interference of the noise with the surrounding working environment, but also greatly reduces the risk of wear and tear and rupture damage of the pipeline 1 due to long-term impact, prolongs the service life of the pipeline 1, and ensures the stability and safety of fluid transportation. The inside middle part of the pipeline 1 is fixedly connected with a sealing ring 22. The sealing ring 22 tightly surrounds the inside of the pipeline 1 and is firmly combined with the inner wall of the pipeline 1 through a special installation process. During the fluid transportation process, the pressure inside the pipeline 1 is high, and if the sealing performance is not good, fluid leakage may easily occur, which not only causes resource waste but also causes safety hazards. The sealing ring 22 acts like a tight barrier, filling the small gaps at the connection of the pipeline 1 with its good elasticity and sealing performance, enhancing the sealing performance of the inside of the pipeline 1 and ensuring that the fluid can be stably transported along the predetermined path in the pipeline 1, ensuring the efficient operation of the entire structure. The front side of the sealing ring 22 is fixedly connected with a flow guide block 23 made of smooth metal material. When the fluid flows through the pipeline 1, the flow direction of the fluid inside the pipeline 1 is easily disturbed due to the complex internal structure of the pipeline 1, which increases the flow resistance and affects the transportation efficiency. The flow guide block 23 can guide the flow direction of the fluid in the pipeline 1, making the fluid flow along a specific path, reducing the turbulence and eddy current inside the fluid, reducing the flow resistance, and improving the transportation capacity and operation stability of the entire device. The box body 11, as an important container for collecting impurities and liquid in the pipeline 1, is fixedly connected with a gasket 24 at the bottom. The gasket 24 is made of soft and slightly adhesive rubber material. Although the threaded connection can provide a certain sealing performance at the connection between the bottom of the box body 11 and the threaded plug 12, in actual use,Due to the influence of vibration, temperature change factors, there is still a small gap between the threads, causing the collected impurities or liquid leakage, the gasket 24 can be tightly filled between the threaded plug 12 and the gap between the bottom of the box 11, with its own viscosity and elasticity, further reducing the gap between the two, enhancing the sealing effect, effectively preventing the leakage of substances in the box 11, ensuring that the box 11 can continuously and stably play the impurity and liquid collection function.

[0039] Working principle: when the fluid flows into the pipeline 1, it first passes through the piston 9, because the piston 9 is a hollow structure, the fluid can pass through the middle into the valve body 3, then rotate the rocker 8, drive the rotation of the ball 6, adjust the flow size in the valve body 3 by controlling the rotation angle of the ball 6, when cleaning is needed, close the valve to stop the fluid flow in the pipeline 1, then manually pull the pull rod 10, drive the piston 9 to slide in the pipeline 1, clean the impurities on the inner wall of the pipeline 1 and make it flow into the box 11, unscrew the threaded plug 12 at the bottom of the box 11, discharge the impurities and liquid collected in the box 11, so as to realize the effect of cleaning the impurities on the inner wall of the pipeline 1, ensuring the normal flow of fluid in the pipeline 1 and maintaining the stable operation of the whole equipment;

[0040] The fluid in the pipeline 1 will first flow into the filter bucket 201, and the screen 206 in the bucket will simply filter the impurities therein, and the filtered fluid will flow into the pipeline 1, and the filtered impurities will accumulate at the bottom of the filter screen 206, when there is no fluid in the bucket, open the cover 204, pull the handle 16 to easily take out the filter screen 206, clean the filter screen 206, prolong the service life of the filter screen 206, and ensure the filtering effect.

[0041] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
