Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline switching valve technology, specifically a multi-energy coupled pipeline switching valve. Background Technology
[0002] The switching valve is the core control device of multi-energy coupling pipeline. It prevents energy crosstalk by isolating the medium, realizes flexible switching of the process to optimize energy supply, has emergency shut-off to ensure safety, supports segmented maintenance to reduce downtime, and ensures stable operation of multiple energy sources under different parameters such as pressure and temperature.
[0003] A liquid valve disclosed in patent publication number CN216143201U includes a connecting rod and a second through hole. During operation, a wedge-shaped slider is pressed towards the spring, placing it within the second through hole of the connecting rod. The movable rod is then pushed downwards until the slot is flush with the third through hole. Under the restoring force of the spring, the wedge-shaped slider slides away from the spring, locking into the slot, thus installing the handle. Rotating the handle causes the flow pointer to point to a designated scale on the dial. After flow adjustment, pulling the handle upwards moves the movable rod upwards, causing the wedge-shaped slider to move against the spring's elasticity and retract into the third through hole. Continuing to pull the handle upwards removes it from the connecting rod, preventing accidental operation from affecting chemical production. When adjusting the valve again, the above operation is repeated, attaching the handle to the connecting rod via the movable rod for valve adjustment.
[0004] The aforementioned device uses a wedge-shaped slider and a spring to rotate the valve stem by engaging it in a slot. During rotation, the wedge-shaped slider is prone to radial wobble, affecting operational accuracy. Secondly, axial downward pressure and rotational torque must be applied simultaneously during operation. If the pressure is insufficient, the slider may dislodge from the slot, posing a risk of operational failure. Therefore, stability needs to be improved. To address these issues, a multi-energy coupling pipeline switching valve is proposed. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 Figures 1-4 In this embodiment, a multi-energy coupling pipeline switching valve includes a valve body 11, a valve ball 15 rotatably connected within the valve body 11, a fixed seat 12 mounted on the top of the valve body 11, and a valve stem 13 rotatably connected within the valve body 11. The bottom of the valve stem 13 is connected to the valve ball 15, and a handle 14 is connected to the valve stem 13 via a fixing component. One end of the handle 14 is fixedly connected to a positioning block 16. At least three sets of arc-shaped fixing blocks 17 are fixedly connected to the fixed seat 12. The positioning block 16 is slidably disposed within the arc-shaped fixing block 17, and a limiting component for positioning the positioning block 16 is provided within the arc-shaped fixing block 17.
[0026] The limiting component includes a moving groove 20 and a locking block 19. The moving groove 20 is located at the bottom of the inner wall of the arc-shaped fixing block 17 and extends through the fixing seat 12. The locking block 19 is slidably connected within the moving groove 20. The bottom of the positioning block 16 has a locking groove 18 for engaging the locking block 19. The bottom of the locking block 19 is connected to a spring 21. The end of the spring 21 away from the locking block 19 is connected to the bottom of the inner wall of the moving groove 20. The bottom of the locking block 19 is fixedly connected to a positioning rod 22. The spring 21 is sleeved on the positioning rod 22, and the positioning rod 22 extends out of the moving groove 20. When the handle 14 is rotated, the positioning block 16 connected to it moves in an arc-shaped trajectory within a track formed by at least three sets of arc-shaped fixing blocks 17. During rotation, the bottom of the positioning block 16 gradually contacts the locking block 19 in the moving groove 20 and applies pressure, forcing the locking block 19 to overcome the elastic force of the spring 21 and slide downward along the moving groove 20, simultaneously compressing the spring 21 and causing the positioning rod 22 to move downward. Until the slot 18 on the positioning block 16 is precisely aligned with the moving slot 20, the spring force of the spring 21 will quickly lift the block 19 and make it lock into the slot 18, thus achieving initial positioning. If the handle 14 needs to be rotated further, thanks to the arc-shaped structure design at the top of the block 19, the squeezing force generated by the positioning block 16 on the block 19 when rotating will cause the block 19 to slide down along the moving slot 20 again, which can reduce the shaking amplitude of the positioning block 16 when the valve stem 13 is rotated, and ensure the accuracy and stability of the pipeline switching operation.
[0027] The arc-shaped fixing block 17 is provided with a positioning component for fixing the positioning block 16.
[0028] The fixing component includes a through hole 26 and a fixing ring 27. The through hole 26 is formed on the handle 14, and the fixing ring 27 is threaded to the valve stem 13. The bottom of the fixing ring 27 overlaps with the top of the handle 14. Both the through hole 26 and the valve stem 13 have rectangular cross-sections. The through hole 26 on the handle 14 is precisely inserted into the valve stem 13. The fitting design of their rectangular cross-sections achieves a tight circumferential limiting fit, effectively preventing the handle 14 from rotating relative to the valve stem 13. Subsequently, the fixing ring 27 is threaded to the valve stem 13. By rotating the fixing ring 27, its bottom is tightly overlapped with the top of the handle 14, further limiting the handle 14 axially. This double limiting structure not only reduces the possible shaking of the valve stem 13 when the handle 14 rotates, but also ensures that the force of operating the handle 14 can be stably and efficiently transmitted to the valve stem 13, avoiding the valve stem 13's inability to drive the valve ball 15 to rotate normally due to the handle 14 spinning freely, thereby ensuring the accuracy and stability of pipeline switching operations.
[0029] The positioning component includes a first fixing groove 23 and a second fixing groove 25. The first fixing groove 23 is formed on the positioning block 16, and the second fixing groove 25 is formed on the arc-shaped fixing block 17 and passes through the fixing seat 12. The second fixing groove 25 and the first fixing groove 23 are internally threaded with a set of fixing rods 24. After sliding to the designated position, the locking block 19 is locked into the locking groove 18. The two sets of fixing rods 24 are inserted into the first fixing groove 23 and the second fixing groove 25 and rotated to fix the positioning block 16 and the arc-shaped fixing block 17. This can prevent the positioning block 16 from shaking and falling out of the arc-shaped fixing block 17, thus improving stability.
[0030] The top of the locking block 19 is set to be arc-shaped. By setting the locking block 19 to be arc-shaped, the positioning block 16 can be positioned easily when rotating, and the rotation angle of the valve ball 15 can be easily adjusted.
[0031] The handle 14 is equipped with a rubber pad, which can cover the part of the handle 14 held by the operator, reducing the possibility of accidental injury to the operator when operating the handle 14.
[0032] The side of the positioning block 16 connected to the arc-shaped fixing block 17 is arc-shaped. By setting one side of the positioning block 16 to be arc-shaped, it can slide more closely to the arc-shaped fixing block 17, avoiding gaps that could cause the card block 19 and the card slot 18 to misalign.
[0033] The working principle of this utility model is as follows: In use, firstly, the through hole 26 on the handle 14 is engaged with the valve stem 13. A retaining ring 27 is threaded onto the valve stem 13 to limit the position of the handle 14. During adjustment, the handle 14 is rotated, causing the valve stem 13 to rotate. The valve stem 13 then rotates the valve ball 15 within the valve body 11, thereby changing the direction of liquid flow and switching the pipeline. When the handle 14 rotates, the positioning block 16 rotates within at least three sets of arc-shaped fixing blocks 17. During rotation, it presses against the locking block 19, causing the locking block 19 to press downwards against the spring 21 and the positioning rod 22 within the moving groove 20. The rotation continues until the locking groove 18 and the moving groove 20 are engaged. During alignment, the spring force of spring 21 is used to pop the locking block 19 upward and lock it into the locking slot 18. When the lever handle 14 is rotated, due to the arc shape of the locking block 19 surface, the locking block 19 is squeezed and slides downward in the moving slot 20 during rotation. This can reduce the wobbling of the positioning block 16 during the rotation of the valve stem 13, which would affect the accuracy. After sliding to the designated position, the locking block 19 is locked into the locking slot 18. Two sets of fixing rods 24 are inserted into the first fixing slot 23 and the second fixing slot 25 for rotation to fix the positioning block 16 and the arc-shaped fixing block 17. This can prevent the positioning block 16 from wobbling and falling out of the arc-shaped fixing block 17, thus improving stability.
[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
