Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a ball valve with a heat dissipation structure. Background Art

[0002] In order to cut off, connect and regulate the medium in the pipeline, the staff usually installs a ball valve on the pipeline to control the fluid in the pipeline. The existing ball valve usually consists of a valve body, a valve cover, a valve stem and a valve ball.

[0003] For example: the utility model with application number CN202020695695.0 discloses a heat dissipation ball valve, specifically including a valve body, the valve body including a side wall, the side wall is provided with a water inlet pipe and a water outlet pipe, the water inlet pipe and the water outlet pipe are connected to each other, the side wall is also provided with a plurality of heat dissipation pipes between the water inlet pipe and the water outlet pipe, the heat dissipation pipe and the water outlet pipe are connected to the same heat collecting pool, the top of the heat collecting pool is provided with an air outlet, one side of the valve body is provided with a plurality of horizontally distributed cross bars, the opening of the valve body is provided with a plurality of vertical bars arranged perpendicular to the cross bars, the valve body is provided with sliding grooves on both sides of the valve body at the opening, and the vertical bars can move in the sliding grooves along the length direction of the cross bars. The utility model has the advantage of enhancing the heat dissipation of the ball valve.

[0004] However, as far as the current traditional ball valve is concerned, the valve body and the valve cover are usually fixed directly by bolts. But when the valve ball needs to be inspected, the staff needs to use tools to unscrew the bolts fixing the valve cover before removing the valve cover to inspect the valve ball. The operation is cumbersome and inconvenient to use. Utility Model Content

[0005] In view of this, the utility model provides a ball valve with a heat dissipation structure, which has a connecting slide that can facilitate the staff to quickly separate the valve cover. The rotating ring is rotated by toggling the rotating ring. The auxiliary torsion spring is twisted during the rotation of the rotating ring. The first wedge block is driven to move through the fixed column during the rotation of the rotating ring. As the first wedge block moves, the second wedge block is squeezed. After the second wedge block is squeezed, it drives the connecting slide to slide along the guide slide rod and squeeze the connecting spring. As the connecting slide slides, the connecting slide will be detached from the connecting slot. At this time, the staff can remove the valve cover and inspect the valve ball.

[0006] The utility model provides a ball valve with a heat dissipation structure, specifically comprising: a valve body; a valve cover is arranged on the top end surface of the valve body; a valve stem is rotatably connected inside the valve cover; an operating handle is fixedly connected to the top end surface of the valve stem; a valve ball is fixedly connected to the bottom end surface of the valve stem; the valve ball is arranged in the valve body; two sealing gaskets are symmetrically arranged in the valve body; the two sealing gaskets are aligned with the position of the valve ball; a plurality of groups of connecting slots are provided on the outside of the valve cover in an annular array; a plurality of groups of guide slide rods are fixedly connected to the upper part of the valve body in an annular array; the plurality of groups of guide slide rods are respectively aligned with the positions of the plurality of groups of connecting slots.

[0008] Optionally, the top surface of the rotating ring is fixedly connected to multiple groups of fixed columns in a circular array; the top surfaces of the multiple groups of fixed columns are fixedly connected to a first wedge block; the outsides of the multiple groups of guide slides are slidably connected to connecting slides; the multiple groups of connecting slides are respectively inserted into the multiple groups of connecting slots; the rear parts of the multiple groups of connecting slides are fixedly connected to connecting springs; the ends of the multiple groups of connecting springs are respectively fixedly connected to the outsides of the multiple groups of guide slides; the lower parts of the multiple groups of connecting slides are fixedly connected to second wedge blocks; the multiple groups of second wedge blocks are respectively aligned with the positions of the multiple groups of first wedge blocks.

[0009] Optionally, two groups of control slides are symmetrically slidably connected in the valve body; a group of control slide rods are fixedly connected to the outer sides of the two groups of control slides; a group of return springs are fixedly connected to the inner sides of the two groups of control slides; and the ends of the two groups of return springs are fixedly connected in the valve body.

[0010] Optionally, a group of transmission racks are fixedly connected to the inner sides of the two groups of control slides; two groups of transmission shafts are symmetrically rotatably connected inside the valve body; the outsides of the two groups of transmission shafts are fixedly connected to transmission gears; the two groups of transmission gears are respectively meshed with the two groups of transmission racks; and sealing baffles are fixedly connected to the outsides of the two groups of transmission shafts.

[0011] Optionally, two groups of heat sinks are symmetrically and fixedly connected to the outside of the valve body; the two groups of heat sinks are aligned with each other.

[0012] Beneficial Effects

[0013] The utility model discloses that when testing the valve ball, the staff can turn the rotating ring to drive the first wedge block to move. As the first wedge block moves, the second wedge block is squeezed. Then, through a series of transmissions, the connecting slide seat is disengaged from the connecting slot. At this time, the staff can remove the valve cover to inspect the valve ball. The operation is simple and quick, which reduces the labor intensity of the staff, effectively improves the convenience of the ball valve, and is more convenient and quick to use.

[0014] When replacing the pipeline, after the pipeline is separated from the ball valve, the control slide plate will be reset under the action of the elastic potential energy of the reset spring itself, and then the transmission shaft will drive the sealing baffle to flip through a series of transmissions, so that the sealing baffle automatically closes to seal the ball valve, preventing the medium from leaking out of the ball valve, effectively improving the convenience of the ball valve.

[0015] The heat sink can provide heat conduction for the ball valve when high-temperature media flows through the ball valve, transferring heat from the ball valve to the surrounding environment, ensuring that the ball valve can still maintain its performance and reliability in a high-temperature environment.
