Description

Technical Field

[0001] The present invention relates to the technical field of ball valves, in particular to a double-track ball valve suitable for high-frequency opening and closing. Background Art

[0002] In modern industrial fluid control systems, ball valves, as an efficient and reliable control element, are widely used in the transportation and control of various media.

[0003] A search revealed Chinese patent publication number CN221525621U, which discloses a track ball valve. While this ball valve allows for smooth and free rolling of the stop pin, reducing friction between the valve stem track groove and the stop pin, and altering the trajectory of the valve stem track groove to increase the turning angle and reduce the stop pin load, the existing track ball valve design relies primarily on the guidance of the valve stem and ball for sealing. Rotation or the push-pull action of the valve stem forces the top end of the valve ball to tilt to one side, allowing the ball to fit tightly against the valve seat, achieving a seal.

[0004] However, this design has a significant technical flaw: the bottom of the valve ball remains stationary during the sealing process, unable to form an effective sealing contact with the valve seat. Due to the low pressure on the contact surface between the bottom of the valve ball and the valve seat, the sealing performance between the lower half of the valve ball and the valve seat is poor. This problem is particularly prominent under high-frequency opening and closing conditions, because frequent opening and closing actions will cause the contact surface between the valve ball and the valve seat to continuously wear, further reducing the sealing performance, and ultimately affecting the reliability and service life of the valve. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a dual-track ball valve that is suitable for high-frequency opening and closing, which solves the problem of uneven pressure between the valve ball and the valve seat sealing surface of the existing track ball valve proposed in the background technology, which easily leads to poor sealing on local sealing surfaces.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a double-track ball valve adapted to high-frequency opening and closing, comprising: A valve body, wherein a medium flow channel is provided inside the valve body; A valve ball is installed inside the valve body and controls the opening and closing of the medium flow channel by rotating; Sealing components, installed at both ends of the valve body, used to connect the valve body with external pipelines; A transmission mechanism, connected to the valve ball, for controlling the valve ball to switch; The hand wheel is located at the top of the transmission mechanism and is connected to the transmission mechanism.

At the same time, the rectangular limiting groove at the top and the sliding connection between the two connecting arms at the bottom and the inside of the valve seat ensure the precise guidance and positioning of the valve ball during the opening and closing process, effectively solving the problem of uneven pressure on the sealing surface between the valve ball and the valve seat in the prior art, and improving the sealing performance and service life of the valve under high-frequency opening and closing conditions. The guide head is always connected to the limiting groove, and the valve ball rotates at an angle of ninety degrees under the restriction of the track.

[0013] Preferably, the outer wall of the guide rod is slidably connected to the slider, and guide posts are bolted to both ends of the slider. The guide posts are slidably connected to the interior of the valve seat. A spring is provided at the top end of the guide post, and the bottom end of the guide post has an inclined surface. This transmission mechanism achieves smooth movement and precise control of the valve ball through the sliding connection between the guide rod and the slider, and the sliding cooperation between the guide posts at both ends of the slider and the interior of the valve seat. The inclined surface structure at the bottom of the guide post and the spring design at the top ensure uniform sealing pressure distribution of the valve ball during opening and closing.

[0014] The present invention provides a double-track ball valve that is adaptable to high-frequency opening and closing. It has the following beneficial effects: To close this dual-track ball valve, the operator turns the handwheel, which rotates the threaded rod. As the threaded rod rotates, its external threads interact with mating components, causing it to move downward, driving the guide rod downward in tandem. The downward movement of the guide rod causes the stop pin to slide within the track. The stop pin moves from the bottom of the track to the top. When it reaches the curved portion in the middle of the track, the stop pin guides the guide rod, allowing it to rotate 90 degrees. The guide head at the bottom of the guide rod engages the stop slot on the valve ball, pulling the valve ball in a synchronous 90-degree rotation, closing the flow path between the valve ball and the valve seat. As the guide rod continues to move downward, the gland pushes the slider downward, which in turn drives the guide post downward. The inclined surface at the bottom of the guide post contacts the connecting arm at the bottom of the valve ball. As the guide post moves downward, the inclined surface forces the connecting arm to move horizontally to one side, thereby driving the bottom of the valve ball in a horizontal displacement. Simultaneously, as the guide rod moves downward, its guide head contacts the top of the stop slot, pushing the stop slot and causing the top end of the valve ball to also move horizontally to one side. The guide mechanism synchronizes the bottom and top of the valve ball with horizontal displacement, allowing the ball's sealing surface to evenly press against the first sealing ring of the sealing seat. This design effectively overcomes the poor sealing performance of the bottom of the traditional orbital ball valve. Even if the valve ball wears, it can still maintain a good sealing effect, ensuring that the valve is suitable for high-frequency opening and closing conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Example 3: Please refer to Figure 1-8 , the embodiment of the present invention provides a technical solution: the sealing component 3 includes an inner copper tube 301, two of the inner copper tubes 301 are provided, one end of the two inner copper tubes 301 is respectively inserted into the valve seat 102 and the connecting seat 101, and the outer wall of the inner copper tube 301 is tightly fitted with the inner wall of the valve seat 102 and the connecting seat 101, the outer wall of the inner copper tube 301 is connected to the sealing gasket 302, and two of the sealing gaskets 302 are provided, and the two sealing gaskets 302 are respectively provided on the valve seat 102 and One end of the connecting seat 101, and the two sealing gaskets 302 are both in contact with the surface of the flange 305, and a second sealing ring 304 is provided on both sides of the sealing gasket 302. The outer side of the sealing gasket 302 is connected to the outer copper tube 303, and the inner wall of the outer copper tube 303 is in contact with the outer wall of the flange 305; the inner copper tube 301, the sealing gasket 302 and the outer copper tube 303 are an integrated structure and are all made of copper. The surface of the outer copper tube 303 is provided with annular grooves, and the grooves are distributed in a spaced pattern; In this embodiment, copper sealing assemblies 3 are provided at both ends of the valve body 1. When the connection between the valve and the external pipeline is exposed to high temperature, the sealing gasket 302 and the inner copper tube 301 will expand under the action of the high temperature, thereby causing the connecting pipe to expand between the valve seat 102 and the flange 305. This further strengthens the sealing between the valve seat and the flange 305 under the action of high temperature. At the same time, the thermal expansion of the inner copper tube 301 will further conform to the inner wall of the inner copper tube 301 and the valve seat 102, further strengthening the sealing between the inner copper tube 301 and the valve seat 102, thereby reducing the impact of high temperature on the connection between the valve and the pipeline, which may cause the sealing to deteriorate.

[0021] The working process of the double-track 403 ball valve in this scheme is as follows: Valve open: The hand wheel 5 is rotated, and the hand wheel 5 drives the threaded rod 401 in the transmission mechanism 4 to rotate.

[0022] The threaded rod 401 moves upward through the threads of the outer wall, thereby driving the guide rod 402 to move upward.

[0023] The movement of the guide rod 402 causes the limiting pin 404 to slide in the track 403 . When the limiting pin 404 moves to the middle arc portion of the track 403 , the guide rod 402 rotates a certain angle under the guidance of the limiting pin 404 .

[0024] The rotation of the guide rod 402 drives the valve ball 2 to rotate, so that the connection channel between the valve ball 2 and the valve seat 102 is opened, and the medium flow channel is opened.

[0025] Valve closed: The hand wheel 5 is rotated, and the hand wheel 5 drives the threaded rod 401 to rotate, and the threaded rod 401 moves downward through the thread of the outer wall.

[0026] The guide rod 402 moves downward accordingly, and the limiting pin 404 slides in the track 403. When the limiting pin 404 moves to the middle arc portion of the track 403, the guide rod 402 rotates a certain angle.

[0027] The guide head 406 at the bottom of the guide rod 402 is connected to the limiting groove 201 on the valve ball 2, driving the valve ball 2 to rotate, so that the connection channel between the valve ball 2 and the valve seat 102 is closed.

[0028] As the guide rod 402 continues to move downward, the guide rod 402 drives the slider 411 to move downward through the pressing block 410 .

[0029] The slider 411 drives the guide post 413 to move downward, and the inclined surface at the bottom of the guide post 413 contacts the connecting arm 202 at the bottom of the valve ball 2, forcing the connecting arm 202 to move horizontally to one side, driving the bottom of the valve ball 2 to move horizontally.

[0030] At the same time, the guide head 406 at the bottom of the guide rod 402 contacts the top of the limiting groove 201, forcing the limiting groove 201 to drive one end of the top of the valve ball 2 to move horizontally to one side.

[0031] Through the guiding effect, the bottom and top of the valve ball 2 are synchronously moved horizontally to one side, so that the sealing surface 203 of the valve ball 2 is evenly pressed against the first sealing ring 104 of the sealing seat 103, thereby closing the valve and maintaining good sealing performance.

[0032] During the entire working process, the cooperation between the transmission mechanism 4 and the valve ball 2, as well as the role of the sealing component 3, ensure that the valve can achieve reliable sealing and stable switching operation under high-frequency opening and closing conditions. The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from all points of view, the embodiments should be regarded as illustrative and non-restrictive.
