Description

Technical Field

[0001] The utility model relates to a single-seat regulating valve, belonging to the technical field of valves. Background Art

[0002] Valves are pipe accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow) of the conveying medium. Based on their function, they can be divided into shut-off valves, check valves, and regulating valves. Valves are control components in fluid conveying systems, performing functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion, and overflow pressure relief. Valves used in fluid control systems come in a wide variety of types and specifications, from the simplest shut-off valves to the various valves used in extremely complex automatic control systems. Valves are devices used to control the direction, pressure, and flow of fluids in fluid systems. They enable or stop the flow of media (liquids, gases, powders) within piping and equipment, and can control their flow.

[0003] Publication number: CN219345635U, mentions a single-seat regulating valve, by rotating the first bolt, the sealing gasket can be moved outside the sleeve rod, so that the sealing gasket clamps the water pipe, which has a sealing effect, thereby improving the sealing of the connection between the single-seat regulating valve and the water pipe. A spring is fixedly connected to the inside of the shell, and a clamping plate is fixedly connected to the outside of the spring, so that the clamping plate can be clamped along with the water pipe. By rotating the second bolt, the water pipe can be limited, which facilitates the installation of the water pipe.

The card block 4 is fixedly connected to the upper surface of one of the fixed clamping rings 3, the docking shell 10 is fixedly connected to the upper end of the other fixed clamping ring 3, the mounting shell 11 is fixedly connected to the upper end of the other fixed clamping ring 3, the sliding card box 14 is slidably connected in the mounting shell 11, the pull rod 12 is fixedly connected to the right end of the sliding card box 14, and the spring 13 is slidably connected to the circumferential surface of the pull rod 12. This design solves the problem that the original device only fixes the external pipeline to the channel of the single-seat regulating valve body 1, and there is still a gap in the connection surface between the single-seat regulating valve body 1 and the pipeline, which causes water leakage during use, resulting in waste of water resources.

[0023] As the first embodiment of the present utility model: a magnetic head 18 is fixedly connected to the lower right end of one of the fixing clamps 3, and a magnetic seat 21 is fixedly connected to the lower right end of the other fixing clamp 3. The magnetic head 18 installed at the lower end of the fixing clamp 3 can replicate the fixing assembly to fix the two fixing clamps 3 by docking with the magnetic seat 21. The upper and lower ends of one of the fixing clamps 3 are fixedly connected to positioning blocks 15. The two positioning blocks 15 are slidably connected to the grooves at the upper and lower ends of the other fixing clamp 3. The positioning blocks 15 installed at the upper and lower ends of the fixing clamp 3 can assist the card block 4 to slide accurately into the docking shell 10 by sliding into the groove of the other fixing clamp 3, so that the sliding card box 14 fixes the card block 4. The front and rear ends of the two slide bars 6 are fixedly connected to the limiting materials 7. The lower ends of the two fixed clamps 3 are fixedly connected to the placement platform 20. The limiting materials 7 installed at both ends of the slide bars 6 can limit the connection sleeve 5 on the surface of the slide bars 6, so that the worker can pull the fixed clamp 3 to move. The placement platform 20 installed at the bottom of the fixed clamp 3 can temporarily support the fixed clamp 3 to stand stably, and can prevent the single-seat regulating valve body 1 from falling sideways when the single-seat regulating valve body 1 is removed. The sliding card box 14 is slidably connected to the square hole of the block 4. The surface of the pull rod 12 is provided with a rubber layer. When the sliding card box 14 slides into the block 4, it can be clamped to the block 4 under the elastic force of the spring 13, thereby fixing the two fixed clamps 3. The rubber layer is provided on the surface of the pull rod 12. When the user pinches the pull rod 12, it can prevent the pull rod 12 from being corroded by hand sweat, while increasing the friction between the finger and the pull rod 12. Two sealing rings 17 are arranged between the two connecting flanges 2, and the block 4 is slidably connected to the docking shell 10. The sealing ring 17 can seal the two connecting flanges 2 by wrapping between the two connecting flanges 2, thereby preventing leakage between the single-seat regulating valve body 1 and the docking water pipe 8. When the block 4 slides into the docking shell 10, the block 4 will push the sliding card box 14 to retract inward. When the sliding card box 14 is aligned with the square hole on the surface of the block 4, the sliding card box 14 will clamp the block 4.

[0024] As a second embodiment of the present invention: the left end of the docking water pipe 8 is aligned with the right end of the single-seat regulating valve body 1, and the two connecting flanges 2 are fixedly connected by bolts, and the two fixing clamps 3 are wrapped around the two connecting flanges 2. At the same time, the clamping block 4 on the surface of the fixing clamping ring 3 slides into the docking shell 10. In the process of penetrating into the docking shell 10, the clamping block 4 pushes the sliding card box 14 inward to retract. When the square hole of the clamping block 4 and the sliding card box 14 are aligned with each other, the sliding card box 14 will clamp the clamping block 4 under the elastic force of the spring 13. The magnetic heads 18 and the magnetic seats 21 at the bottom of the two fixing clamps 3 are adsorbed and connected to each other, so that the two fixing clamps 3 can be fixedly connected. When the two fixing clamps 3 are fixed on the surfaces of the two connecting flanges 2, the two sealing rings 17 will wrap around the surface between the two connecting flanges 2, thereby achieving a sealing treatment for the two connecting flanges 2, thereby preventing water leakage between the single-seat regulating valve body 1 and the docking water pipe 8.
