They are typically installed between pipelines to control on / off states. Existing valves often suffer from limited flow rates, restricting their application scenarios. Furthermore, when installed at pipeline heads or connections, valves are prone to unstable on / off states due to accidental activation or misoperation, resulting in compromised safety. Utility Model Content

[0003] The purpose of this invention is to provide a high-flow-rate valve that can quickly open and close the fluid channel while ensuring the stability of the fluid channel and preventing changes in the fluid's opening and closing state due to accidental contact.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-flow-rate valve, comprising: a tubular body, a sphere rotatably disposed within the tubular body, the sphere having a flow channel through hole in a direction perpendicular to its rotation axis, one end of a rotating handle disposed on the outside of the tubular body being connected to the sphere and used to drive the sphere to rotate; when the sphere rotates to the 0° position with the rotating handle, the direction of the flow channel through hole on the sphere is perpendicular to the axial direction of the tubular body and the outer circumferential surface of the sphere is sealed to the inner wall of the tubular body; when the sphere rotates to the 90° position with the rotating handle, the direction of the flow channel through hole on the sphere is parallel to the axial direction of the tubular body and the internal flow channels of the tubular body located on both sides of the sphere are connected through the flow channel through hole on the sphere.

[0005] A receiving hole is formed on the side surface of the other end of the rotating handle facing the tubular body. A limiting ball that can rotate with the rotating handle is rotatably embedded in the receiving hole. A guide plane is formed on the outer wall of the tubular body to roll with the limiting ball. A strip-shaped groove extending normally along the rolling trajectory of the limiting ball is formed on the rotating handle. A limiting pin is embedded in the strip-shaped groove communicating with the receiving hole. The other end of the limiting pin, which can extend to the outside of the strip-shaped groove, is connected to the bottom surface of the strip-shaped groove. A spring is connected to the limiting pin, which slides in contact with the inner wall of the strip groove. A ring groove is provided in the middle of the limiting pin, into which a limiting ball can be inserted. A stop groove is provided at both ends of the arc-shaped guide plane, into which the limiting ball can be inserted. When the spring is in a compressed state, the limiting ball, which is in rolling contact with the guide plane, is inserted into the stop groove. When the ball is rotated to the 0° and 90° positions and the spring is in a natural state, the limiting ball is inserted into the stop groove at both ends of the guide plane respectively.

[0006] The following are further improvements to the above technical solution:

[0007] 1. In the above scheme, the two opposite sidewalls of the annular groove are set as sloping surfaces that cooperate with the limiting sphere.

[0008] 2. In the above scheme, a limiting annular groove communicating with the annular groove is opened on the limiting pin and on the side of the annular groove near the spring. The annular bottom surface of the limiting annular groove, which is less than the depth of the annular groove, is in abutting contact with the other side of the limiting ball that is embedded in the stop groove on one side.

[0009] 3. In the above scheme, the sidewall of the limiting annular groove is set as a sloping surface that engages with the limiting ball.

[0010] 4. In the above scheme, the inner wall of the stop groove is a spherical surface.

[0011] 5. In the above scheme, a sealing ring is provided between the inner wall of at least one end of the tubular body and the outer circumferential surface of the sphere.

[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0013] This utility model relates to a high-flow-rate valve, in which a sphere is rotatably disposed within a tubular body. When the sphere is rotated to the 0° position with the rotating handle, the direction of the flow channel through-hole on the sphere is perpendicular to the axial direction of the tubular body, and the outer circumferential surface of the sphere is in a sealing fit with the inner wall of the tubular body. When the sphere is rotated to the 90° position with the rotating handle, the direction of the flow channel through-hole on the sphere is parallel to the axial direction of the tubular body, and the internal flow channels of the tubular body located on both sides of the sphere are connected through the flow channel through-hole on the sphere. A receiving hole is opened on the side surface of the rotating handle facing the tubular body, and a limiting sphere that can rotate with the rotating handle is rotatably embedded in the receiving hole. A guide plane that rolls with the limiting sphere is formed on the outer wall of the tubular body. A strip groove extending normally along the rolling trajectory of the limiting sphere is opened on the rotating handle, and a device is embedded in the strip groove communicating with the receiving hole. A limiting pin, with one end extending to the outside of a strip groove, has a spring connected to the bottom surface of the strip groove at the other end. The limiting pin, which slides in contact with the inner wall of the strip groove, has an annular groove in its middle for a limiting ball to be inserted. An arc-shaped guide plane has stop grooves at both ends for the limiting ball to be inserted. When the spring is compressed, the limiting ball, which rolls in contact with the guide plane, is inserted into the stop groove. When the ball rotates to 0° and 90° positions and the spring is in its natural state, the limiting ball is respectively inserted into the stop grooves at both ends of the guide plane. This design allows for rapid opening and closing of the fluid channel, enabling the opening and closing of large-flow fluid channels while ensuring stability in both open and closed states, preventing accidental changes in the fluid's opening and closing state during use.

Detailed Implementation

[0020] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0021] Example 1: A high-flow-rate valve includes: a tubular body 1, a ball 2 rotatably disposed inside the tubular body 1, and a flow channel through hole 3 extending in a direction perpendicular to its rotation axis on the ball 2, which can rotate around one of its diameter directions; a rotating handle 4 disposed on the outside of the tubular body 1, one end of which is connected to the ball 2 and used to drive the ball 2 to rotate; when the ball 2 rotates to the 0° position with the rotating handle 4, the direction of the flow channel through hole 3 on the ball 2 is perpendicular to the axial direction of the tubular body 1 and the outer circumferential surface of the ball 2 is sealed to the inner wall of the tubular body 1; when the ball 2 rotates to the 90° position with the rotating handle 4, the direction of the flow channel through hole 3 on the ball 2 is parallel to the axial direction of the tubular body 1 and the internal flow channels of the tubular body 1 located on both sides of the ball 2 are connected through the flow channel through hole 3 on the ball 2.

[0022] A receiving hole 8 is formed on the side surface of the rotating handle 4 facing the tubular body 1. A limiting ball 91 that can rotate with the rotating handle 4 is rotatably embedded in the receiving hole 8. A guide plane 92 is formed on the outer wall of the tubular body 1 to roll with the limiting ball 91. A strip groove 10 extending normally along the rolling trajectory of the limiting ball 91 is formed on the rotating handle 4. A limiting pin 11 is embedded in the strip groove 10 that communicates with the receiving hole 8. The other end of the limiting pin 11, which can extend to the outside of the strip groove 10, is connected to the bottom surface of the strip groove 10. A spring 12 has an annular groove 13 in the middle of the limiting pin 11 that slides in contact with the inner wall of the strip groove 10, into which a limiting ball 91 can be inserted. The two ends of the arc-shaped guide plane 92 have stop grooves 93 into which the limiting ball 91 can be inserted. When the spring 12 is in a compressed state, the limiting ball 91 that rolls in contact with the guide plane 92 is inserted into the stop groove 93. When the ball 2 rotates to the 0° and 90° positions and the spring 12 is in a natural state, the limiting ball 91 is respectively inserted into the stop grooves 93 at both ends of the guide plane 92.

[0023] When the flow channel needs to be opened, first manually push the end of the rotating handle extending out of the slot into the slot to compress the spring until the annular groove on the rotating handle aligns with the receiving hole, allowing the limiting ball to partially embed into the annular groove through the receiving hole. Then drive the rotating handle to rotate until the ball rotates to a 90° position. During the rotation of the rotating handle, the moving limiting ball rolls into contact with the guide plane on the tubular body until it aligns with the stop groove at one end of the guide plane. At this point, release the rotating handle so that it moves out of the slot and resets under the action of the compressed spring. As the rotating handle moves, the annular groove on the rotating handle gradually moves away from the limiting ball, and the limiting ball embeds into the stop groove under the push of the side surface of the rotating handle. This prevents the rotating handle from rotating under the limiting position of the limiting ball and the stop groove on the tubular body. At this time, the direction of the flow channel through hole on the ball at the 90° position is parallel to the axis of the tubular body, and the internal flow channels of the tubular body on both sides of the ball are connected through the flow channel through hole on the ball, thus opening the flow channel.

[0024] The two opposing sidewalls of the aforementioned annular groove 13 are configured as sloping surfaces that cooperate with the limiting sphere 91.

[0025] On the aforementioned limiting pin 11, on the side of the annular groove 13 near the spring 12, there is a limiting annular groove 14 that communicates with the annular groove 13. The annular bottom surface of the limiting annular groove 14, which is less than the depth of the annular groove 13, is in abutting contact with the other side of the limiting ball 91 that is embedded in the stop groove 93 on one side.

[0026] The sidewall of the aforementioned limiting annular groove 14 is configured as a sloping surface that engages with the limiting ball 91; the inner wall of the aforementioned stopping groove 93 is a spherical surface.

[0027] A sealing ring 5 is provided between the inner wall of at least one end of the tubular body 1 and the outer circumferential surface of the sphere 2; a first annular flange 61 with an inner diameter smaller than the diameter of the sphere 2 is provided on the inner wall of at least one end of the tubular body 1, and a second annular flange 62 with a radially inward direction is provided on the inner wall of the first annular flange 61, and the sealing ring 5 is provided between the second annular flange 62 and the sphere 2.

[0028] Example 2: A high-flow-rate valve includes: a tubular body 1, a ball 2 rotatably disposed inside the tubular body 1, and a flow channel through hole 3 extending in a direction perpendicular to its rotation axis on the ball 2, which can rotate around one of its diameter directions; one end of a rotating handle 4 disposed on the outside of the tubular body 1 is connected to the ball 2 and used to drive the ball 2 to rotate; when the ball 2 rotates to the 0° position with the rotating handle 4, the direction of the flow channel through hole 3 on the ball 2 is perpendicular to the axial direction of the tubular body 1 and the outer circumferential surface of the ball 2 is sealed to the inner wall of the tubular body 1; when the ball 2 rotates to the 90° position with the rotating handle 4, the direction of the flow channel through hole 3 on the ball 2 is parallel to the axial direction of the tubular body 1 and the internal flow channels of the tubular body 1 located on both sides of the ball 2 are connected through the flow channel through hole 3 on the ball 2.

[0029] A receiving hole 8 is formed on the side surface of the rotating handle 4 facing the tubular body 1. A limiting ball 91 that can rotate with the rotating handle 4 is rotatably embedded in the receiving hole 8. A guide plane 92 is formed on the outer wall of the tubular body 1 to roll with the limiting ball 91. A strip groove 10 extending normally along the rolling trajectory of the limiting ball 91 is formed on the rotating handle 4. A limiting pin 11 is embedded in the strip groove 10 that communicates with the receiving hole 8. The other end of the limiting pin 11, which can extend to the outside of the strip groove 10, is connected to the bottom surface of the strip groove 10. A spring 12 has an annular groove 13 in the middle of the limiting pin 11 that slides in contact with the inner wall of the strip groove 10, into which a limiting ball 91 can be inserted. The two ends of the arc-shaped guide plane 92 have stop grooves 93 into which the limiting ball 91 can be inserted. When the spring 12 is in a compressed state, the limiting ball 91 that rolls in contact with the guide plane 92 is inserted into the stop groove 93. When the ball 2 rotates to the 0° and 90° positions and the spring 12 is in a natural state, the limiting ball 91 is respectively inserted into the stop grooves 93 at both ends of the guide plane 92.

[0030] When switching the flow channel from the open to the closed state, first manually push the end of the rotating handle extending from the slot into the slot to compress the spring until the annular groove on the rotating handle aligns with the receiving hole, allowing the limiting ball to partially embed into the annular groove through the receiving hole. Then drive the rotating handle to rotate until the ball rotates from the 90° position to the 0° position. During the rotation of the rotating handle, the limiting ball, moving with the rotating handle, crawls out from the stop groove on one end of the guide plane and contacts the guide plane, simultaneously embedding into the annular groove. Then, the limiting ball rolls into contact with the guide plane on the tubular body. Until it aligns with the stop groove at the other end of the guide plane, release the rotating handle so that it moves out of the slot under the action of the compressed spring and resets. As the rotating handle moves, the annular groove on the rotating handle gradually moves away from the limiting ball, and the limiting ball is pushed into the stop groove by the side surface of the rotating handle. This makes the rotating handle unable to rotate under the limiting ball and the stop groove on the tubular body. At this time, the direction of the flow channel through hole on the ball at the 0° position is perpendicular to the axis of the tubular body, and the outer circumferential surface of the ball is sealed with the inner wall of the tubular body, and the flow channel is closed.

[0031] The two opposing sidewalls of the aforementioned annular groove 13 are configured as sloping surfaces that cooperate with the limiting sphere 91.

[0032] On the aforementioned limiting pin 11, on the side of the annular groove 13 near the spring 12, there is a limiting annular groove 14 that communicates with the annular groove 13. The annular bottom surface of the limiting annular groove 14, which is less than the depth of the annular groove 13, is in abutting contact with the other side of the limiting ball 91 that is embedded in the stop groove 93 on one side.

[0033] The end of the rotating handle 4 connected to the ball 2 has a protrusion 41 that extends radially into the tubular body 1. One end of the protrusion 41, which is connected to the ball 2 by a bolt, is embedded in the ball 2.

[0034] A sealing ring is provided between the protrusion 41 that rotatably engages with the tubular body 1 and the tubular body 1; the sphere 2 is connected to the inner wall of the tubular body 1 on the side opposite to the rotating handle 4 via a rotating shaft 7.

[0035] The working principle of this utility model is as follows:

[0036] It is generally used in conjunction with fluid pipelines to switch the open and closed states of fluid flow within the pipeline;

[0037] When the flow channel needs to be opened, first manually push the end of the rotating handle extending out of the slot into the slot to compress the spring until the annular groove on the rotating handle aligns with the receiving hole, allowing the limiting ball to partially embed into the annular groove through the receiving hole. Then drive the rotating handle to rotate until the ball rotates to a 90° position. During the rotation of the rotating handle, the limiting ball, which moves accordingly, rolls into contact with the guide plane on the tubular body until it aligns with the stop groove at one end of the guide plane. At this point, release the rotating handle so that it moves out of the slot and resets under the action of the compressed spring. As the rotating handle moves, the annular groove on the rotating handle gradually moves away from the limiting ball, and the limiting ball embeds into the stop groove under the push of the side surface of the rotating handle. This prevents the rotating handle from rotating under the limiting position of the limiting ball and the stop groove on the tubular body. At this time, the direction of the flow channel through hole on the ball at the 90° position is parallel to the axis of the tubular body, and the internal flow channels of the tubular body on both sides of the ball are connected through the flow channel through hole on the ball, thus opening the flow channel.

[0038] When switching the flow channel from the open to the closed state, first manually push the end of the rotating handle extending from the slot into the slot to compress the spring until the annular groove on the rotating handle aligns with the receiving hole, allowing the limiting ball to partially embed into the annular groove through the receiving hole. Then drive the rotating handle to rotate until the ball rotates from the 90° position to the 0° position. During the rotation of the rotating handle, the limiting ball, moving with the rotating handle, crawls out from the stop groove on one end of the guide plane and contacts the guide plane, simultaneously embedding into the annular groove. Then, the limiting ball rolls into contact with the guide plane on the tubular body. Until it aligns with the stop groove at the other end of the guide plane, release the rotating handle so that it moves out of the slot under the action of the compressed spring and resets. As the rotating handle moves, the annular groove on the rotating handle gradually moves away from the limiting ball, and the limiting ball is pushed into the stop groove by the side surface of the rotating handle. This makes the rotating handle unable to rotate under the limiting ball and the stop groove on the tubular body. At this time, the direction of the flow channel through hole on the ball at the 0° position is perpendicular to the axis of the tubular body, and the outer circumferential surface of the ball is sealed with the inner wall of the tubular body, and the flow channel is closed.

[0039] When using the aforementioned high-flow-rate valve, it can quickly open and close the fluid channel, and ensure the stability of the fluid channel in both open and closed states, thus avoiding changes in the fluid's open and closed state due to accidental contact during use.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
