Description

Technical Field

[0001] This utility model relates to the field of fluoropolymer-lined ball valve technology, specifically to high-performance fluoropolymer-lined ball valves. Background Technology

[0002] Fluorine-lined ball valves use a ball with a circular through hole as the opening and closing element. The ball rotates around the valve body centerline with the valve stem to open and close the valve. A special molding process is used to make the sealing surface dense and good. The ball and valve stem are cast as one piece, eliminating the possibility of the valve stem being pushed out of the pressure-bearing part due to pressure changes, thus fundamentally ensuring safety during use. The all-plastic lining process is used to resist strong corrosion of the media.

[0003] For example, patent document CN 221683660 U discloses a novel fluoropolymer-lined high-performance ball valve, including a first valve body, a second valve body mounted on one side of the first valve body, a valve ball between the first and second valve bodies, a rotating shaft mounted on the valve ball, a connecting plate on the upper part of the first valve body, one end of the rotating shaft penetrating the connecting plate, a spiral groove on the rotating shaft, movable blocks at both ends on one side of the first valve body, and a threaded rod at the lower part of the first valve body. In this invention, rotating the threaded rod causes the two movable blocks to move closer together along the threaded rod. Through the action of a connecting rod, the connecting plate moves upward along the rotating shaft. Under the action of the spiral groove, the connecting plate drives the rotating shaft to rotate, and the valve ball rotates accordingly, opening the fluoropolymer-lined ball valve. The threaded rod limits and fixes the movable blocks, preventing the valve ball from rotating during material conveying, improving the stability and accuracy of the conveying system, and ensuring the efficiency of material conveying.

[0004] However, in practice, workers often have to rely on the torque of the valve stem to tighten the ball inside the fluoropolymer-lined ball valve. This can easily lead to loosening during subsequent sealing, affecting the overall sealing performance. Furthermore, the equipment cannot be reinforced to better fit the ball's position, failing to meet daily usage requirements. Therefore, there is an urgent need to design a high-performance fluoropolymer-lined ball valve to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a high-performance fluoropolymer-lined ball valve to solve the problem mentioned in the background art. In actual operation, the existing structure of the fluoropolymer-lined ball valve can only be tightened by the torque of its own valve stem. This can easily lead to loosening during the subsequent sealing process, affecting the overall sealing performance. At the same time, the equipment cannot perform reinforcement operations to better fit the position of the ball, which cannot meet the needs of daily use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-performance PTFE-lined ball valve, comprising a valve body, with pipe seats fixedly connected to both ends of the valve body, a control seat fixedly connected to the top of the valve body, a control component provided at the top of the control seat, and a locking component provided at the center of the side of the valve body;

[0007] The control assembly includes a rotating sleeve, the rotating sleeve is fixedly connected to the surface of the control seat, and a threaded rod is movably arranged inside the rotating sleeve;

[0008] The locking assembly includes an arc-shaped cover, which is fixedly connected to the center of the side of the valve body.

[0009] Preferably, the arc-shaped cover is provided with air control valve ports at both ends, and the inner wall of the arc-shaped cover is provided with a telescopic arc groove at the center.

[0010] Preferably, the telescopic arc groove is provided with a telescopic airbag inside, and the inner wall of the telescopic airbag is fixedly connected with a reinforcing arc insert plate.

[0011] Preferably, a rotating valve stem is fixedly connected to the bottom end of the threaded rod, and damping rubber strips are provided at the four corners of the side of the rotating valve stem.

[0012] Preferably, a valve ball is fixedly connected to the bottom end of the rotating valve stem, and the valve ball has arc-shaped reinforcing grooves evenly distributed at the four corners of its side.

[0013] Preferably, a control air pump is provided at one end of the surface of the control seat, and control air valve seats are provided at the center of both sides of the control seat.

[0014] Preferably, the inner wall of the valve body is provided with a sealing inner ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This high-performance PTFE-lined ball valve, through its valve body, connecting pipe seat, regulating seat, arc-shaped cover, air control valve port, telescopic arc groove, telescopic air bladder, reinforcing arc insert plate, air control pump, and air control valve seat, enables the equipment to perform high-performance sealing and switching operations on the PTFE-lined ball valve. In actual use, the operator first connects the pipeline to the connecting pipe seats at both ends of the valve body. Normally, the valve ball inside the valve body is rotated by the threaded rod and the rotating valve stem, thus realizing the opening and closing operation of the PTFE-lined ball valve inside the valve body. At the same time, the air control pump at one end of the regulating seat can be activated to supply air to the air control valve ports at both ends of the arc-shaped cover through the air control valve seats on both sides of the regulating seat. This causes the telescopic air bladder at the telescopic arc groove on the inner wall of the arc-shaped cover to expand and contract accordingly, and the reinforcing arc insert plate on the inner wall fits onto the side of the valve ball, further reinforcing the valve ball inside the valve body and ensuring the overall performance, demonstrating the practicality of the equipment design.

[0017] This high-performance PTFE-lined ball valve, through its valve body, regulating seat, rotating sleeve, threaded rod, rotating valve stem, damping rubber strip, valve ball, arc-shaped reinforcing groove, and sealing inner ring, further enhances the overall performance of the equipment. During daily use, operators can install the valve ball inside the valve body via the rotating valve stem and threaded rod. The sealing inner ring inside the valve body can fit snugly against the valve ball. The rotating valve stem can then be damped and limited at the four corners of the regulating seat and rotating sleeve via the damping rubber strips. Furthermore, when the valve ball rotates to the open / close position, the telescopically connected reinforcing arc-shaped insert plate can be switched and plugged into the arc-shaped reinforcing grooves at the four corners of the valve ball's side, ensuring the internal stability of the valve ball during opening and closing, demonstrating the comprehensiveness of the equipment design.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5One embodiment provided by this utility model:

[0026] A high-performance PTFE-lined ball valve includes a valve body 1, with pipe seats 2 fixedly connected to both ends of the valve body 1, a control seat 3 fixedly connected to the top of the valve body 1, a control component on the top of the control seat 3, a locking component at the center of the side of the valve body 1, a control air pump 15 at one end of the surface of the control seat 3, control air valve seats 16 at the center of both sides of the control seat 3, and a sealing inner ring 17 on the inner wall of the valve body 1. The valve ball 13 is installed inside the valve body 1 by rotating the valve stem 11 and the threaded rod 5. The sealing inner ring 17 inside the valve body 1 can fit snugly with the valve ball 13. At this time, rotating the valve stem 11 can perform damping and limiting operation at the back of the control seat 3 and the rotating sleeve 4 through the damping rubber strips 12 at the four corners of the side.

[0027] The control assembly includes a rotating sleeve 4, which is fixedly connected to the surface of the control seat 3. A threaded rod 5 is movably arranged inside the rotating sleeve 4. The locking assembly includes an arc-shaped cover 6, which is fixedly connected to the center of the side of the valve body 1. Air control valve ports 7 are provided at both ends of the arc-shaped cover 6. A telescopic arc groove 8 is opened at the center of the inner wall of the arc-shaped cover 6. A telescopic air bladder 9 is arranged inside the telescopic arc groove 8. A reinforcing arc insert plate 10 is fixedly connected to the inner wall of the telescopic air bladder 9. The threaded rod 5... A rotating valve stem 11 is fixedly connected to the bottom end. Damping rubber strips 12 are provided at the four corners of the side of the rotating valve stem 11. A valve ball 13 is fixedly connected to the bottom end of the rotating valve stem 11. Arc-shaped reinforcing grooves 14 are evenly provided at the four corners of the side of the valve ball 13, so that the telescopic airbag 9 at the telescopic arc groove 8 on the inner wall of the arc-shaped cover 6 can be adapted to telescopic, and the reinforcing arc insert plate 10 on the inner wall can be adapted to be abutted to the side of the valve ball 13, so as to further reinforce the valve ball 13 inside the valve body 1.

[0028] Working principle: During use, the user first connects the pipeline to the pipe fittings 2 at both ends of the valve body 1. Normally, the threaded rod 5 and the rotating valve rod 11 drive the valve ball 13 inside the valve body 1 to rotate, thus opening and closing the PTFE-lined ball valve inside the valve body 1. Simultaneously, the air pump 15 on one end of the control seat 3 can be activated, supplying air through the air control valve seats 16 on both sides of the control seat 3 to the air control valve ports 7 at both ends of the arc-shaped cover 6. This causes the telescopic airbags 9 at the telescopic arc grooves 8 on the inner wall of the arc-shaped cover 6 to extend and retract, fitting the reinforcing arc plate 10 on the inner wall to the side of the valve ball 13, further reinforcing the valve ball 13 inside the valve body 1. To ensure overall performance, during daily use, the operator can install the valve ball 13 inside the valve body 1 by rotating the valve stem 11 and threaded rod 5. The sealing inner ring 17 inside the valve body 1 can fit snugly with the valve ball 13. At this time, rotating the valve stem 11 can perform damping and limiting operation on the back of the control seat 3 and the rotating sleeve 4 through the damping rubber strips 12 at the four corners of the side. At the same time, when the valve ball 13 is rotated to the switch position, the telescopic top-connected reinforcing arc insert plate 10 can perform switching adaptation insertion operation at the arc-shaped reinforcing grooves 14 at the four corners of the side of the valve ball 13, thereby ensuring the internal firmness of the valve ball 13 when the PTFE-lined ball valve is switched. The above is the complete working principle of this utility model.
