Description

Technical Field

[0001] The utility model belongs to the technical field of ball valves, in particular to a low-friction and high-life ball valve. Background Art

[0002] A ball valve is a valve whose opening and closing part is a sphere. The ball rod is driven by the valve stem and rotates around the axis of the valve stem. The ball is provided with a channel for the flow of medium. The medium flows in the channel of the ball to achieve conduction. When the ball rotates until the channel is closed, it blocks the medium and achieves blocking.

[0003] When the existing ball valve is in use, water usually flows in the pipe. Due to the presence of more impurities and particles in the water flow, long-term use will cause the internal ball to be constantly rubbed, causing serious wear of the ball, which not only reduces the service life of the ball, but also seriously affects the sealing effect and causes waste of water resources. Therefore, we propose a low-friction and long-life ball valve. Utility Model Content

[0004] The purpose of the utility model is to provide a low-friction and high-life ball valve. The utility model sets a filter assembly, specifically, after the filter box is placed, the connecting pipe is fixed to the left side of the valve body by bolts. When the water flows, the filter box intercepts impurities and particles in the water flow, reduces the contact between the particles and the ball, thereby reducing the friction with the ball and increasing the service life of the ball. This solves the problem that the long-term use of the existing ball valve will cause the internal ball to be constantly rubbed, thereby causing serious wear of the ball and reducing the service life of the ball.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] A rotating shaft is fixedly connected to the bottom of the valve, and the bottom of the rotating shaft passes through the valve body and extends to the inside. The bottom of the rotating shaft is rotatably connected to the bottom of the inner wall of the valve body, and a ball is fixedly connected to the outer surface of the rotating shaft. By setting a filter assembly, specifically, after the filter box is placed, the connecting pipe is fixed to the left side of the valve body by bolts. When the water flows, the filter box intercepts impurities and particles in the water flow, reduces the contact between the particles and the ball, thereby reducing the friction with the ball and increasing the service life of the ball.

[0008] Furthermore, the left side of the filter box contacts with a guide ring, the right side of the inner wall of the filter box contacts with a rotating rod, a limiting hole groove is provided on the right side of the rotating rod, the inner wall of the limiting hole groove is rotatably connected with a fixed shaft, and the fixed shaft is used to support and limit the rotating rod. When the rotating rod is pulled, the filter box can be driven to move through the fixed shaft, which is convenient for taking the filter box.

[0009] Furthermore, a plurality of positioning holes are opened on the left side of the filter box, a placement ring is fixedly connected to the inner wall of the filter box, and a sealing ring is in contact with the left side of the placement ring. The sealing ring is used to seal, and when the connecting pipe and the valve body are installed and fixed, the guide ring will be squeezed, so that the guide ring and the sealing ring are tightly attached.

[0010] Furthermore, the outer surface of the guide ring is provided with a plurality of sliding grooves, the inner wall of the sliding groove is slidably connected with an arc-shaped clamping plate, the left side of the arc-shaped clamping plate is fixedly connected with a limit plate, and the right side of the guide ring is fixedly connected with a plurality of positioning blocks. By setting the arc-shaped clamping plate, specifically, the guide ring is sleeved on the left side of the filter box, the arc-shaped clamping plate will be squeezed into the inside of the guide ring after contacting the filter box, thereby squeezing the spring sheet, and the arc-shaped clamping plate will be tightly attached to the inner wall of the filter box under the elastic action of the spring sheet, thereby preventing the guide ring from falling off during installation and making the operation more convenient.

[0011] Furthermore, a spring sheet is arranged inside the slide groove, and a rotating hole is opened at the top and bottom of the spring sheet, and the inner walls of the two rotating holes are rotatably connected with a connecting shaft, and the front and back sides of the two connecting shafts are fixedly connected with connecting blocks, and the right side of the connecting pipe contacts the left side of the guide ring, and the top of the connecting block located above is fixedly connected to the bottom of the arc-shaped clamping plate, and the bottom of the connecting block located below is fixedly connected to the bottom of the inner wall of the slide groove, and the spring sheet can rotate on the connecting shaft so that it can be squeezed smoothly.

[0012] Furthermore, a cleaning plate is fixedly connected to the bottom of the rotating rod, the right side of the cleaning plate contacts the inner wall of the filter box, and the right side of the fixed shaft is fixedly connected to the right side of the inner wall of the filter box. The cleaning plate can quickly clean the inner wall of the filter box, making it convenient to remove particulate matter inside the filter box for next use.

[0013] Furthermore, the outer surface of the sphere contacts the inner wall of the valve body, a positioning ring is fixedly connected to the inner wall of the valve body, the right side of the filter box contacts the left side of the positioning ring, the outer surface of the filter box contacts the inner wall of the valve body, the positioning block is matched with the positioning hole, the outer surface of the arc-shaped clamping plate contacts the inner wall of the filter box, and the right side of the guide ring contacts the sealing ring. After the guide ring is placed inside the filter box, the guide ring is rotated to make the positioning block enter the positioning hole, thereby positioning the guide ring and completing the installation, which can make the guide ring more stable after installation.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model sets a filter assembly, specifically, after the filter box is placed, the connecting pipe is fixed to the left side of the valve body by bolts. When the water flows, the filter box intercepts impurities and particles in the water flow, reduces the contact between the particles and the sphere, thereby reducing the friction with the sphere and increasing the service life of the sphere.

[0016] 2. The utility model sets an arc-shaped clamping plate, specifically, sets the guide ring on the left side of the filter box. After the arc-shaped clamping plate contacts the filter box, it will be squeezed into the guide ring, thereby squeezing the spring piece.

After the arc clamping plate 321 contacts the filter box 131, it will be squeezed into the guide ring 132. The arc clamping plate 321 squeezes the spring piece 324 through the upper connecting shaft 325 and the connecting block 326, so that the guide ring 132 can smoothly enter the filter box 131. Then, by rotating the guide ring 132, the positioning block 323 enters the positioning hole 313, so that the guide ring 132 is positioned and the installation is completed.

By rotating the valve 12 to drive the rotating shaft 121 to rotate, the rotating shaft 121 drives the ball 122 to rotate, and the opening and closing of the valve body 1 are adjusted. Then, the water flow will first pass through the filter box 131 for filtering. The guide ring 132 and the rotating rod 133 are used to play a guiding role, and the filter box 131 intercepts impurities and particles in the water flow, reduces the contact between particles and the ball 122, thereby reducing the friction with the ball 122 and improving the ball The service life of the body 122 is shortened, and the intercepted particles will remain in the filter box 131. When the inside of the filter box 131 needs to be cleaned, the connecting pipe 11 is first disassembled, and then the rotating rod 133 is pulled to take out the filter box 131, and then the guide ring 132 is pulled to disassemble it, and the arc clamping plate 321 is reset under the elastic action of the spring piece 324, which is convenient for the next installation, and the limiting plate 322 is used to play a limiting role to prevent the arc clamping plate 321 from moving too far.
