Detailed Description
The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.
As shown in fig. 1-6, the embodiment of the application discloses a ball valve, which comprises a shell 10, wherein a valve core 23 is rotatably arranged in the shell 10, and a channel 24 is arranged in the middle of the valve core 23 and used for overcurrent; the upper end of the valve core 23 is provided with a driving module, the inlet and outlet of the shell 10 is inclined inwards, and the driving module is provided with a sealing module, the driving module is used for completing the basic switching function of the valve body, and the sealing module is used for sealing the valve core 23 and the opening.
In an embodiment, the sealing module includes an adjustable main ring 20 disposed at the inlet and outlet of the housing 10, a plurality of rubber rings are disposed at the outer edge of the adjustable main ring 20, the rubber rings contact with the outer wall of the inlet and outlet of the housing 10, which is inclined inwards, a middle sealing ring 19 is disposed at the side of the adjustable main ring 20 contacting the valve core 23, and an adjusting mechanism is abutted to the side of the adjustable main ring 20 away from the valve core 23.
In this example, the adjusting mechanism includes an adjusting block 17 abutting against the adjustable main ring 20, a screw 16 is rotatably disposed at an upper end of the adjusting block 17, the screw 16 is in threaded connection with the housing 10, and an adjusting button 15 is disposed at an outer end of the screw 16. When the sealing is not tight, the adjusting knob 15 may be screwed to enable the screw 16 to push the adjusting block 17 to move downwards, and the adjusting block 17 abuts against the adjustable main ring 20 and the contact surface is inclined, so the adjusting block 17 can push the adjustable main ring 20 to move inwards in the moving process, and the flange sealing ring 18 can further increase the sealing effect in the moving process and weaken the sealing not tight caused by aging of the flange sealing ring 18, and the middle sealing ring 19 can further cling to the valve core 23, so that the sealing effect of the middle part is guaranteed.
In an embodiment, the shape of the adjusting block 17 aims to push the adjustable main ring 20, as shown in fig. 7, the adjusting block 17 is annular, and the cross section is triangular, when the adjusting block is solid, the cross section of the water inlet pipe orifice is affected in the downward moving process, so that the cross section is reduced, and the purpose of auxiliary flow adjustment is achieved; when the water inlet pipe is of a mesh structure, the section of the water inlet pipe orifice is smaller, but the flow rate is not changed greatly.
Further, the adjustment mechanism may be replaced with a hydraulic push or other mechanism that achieves the same function.
In an embodiment, the driving module comprises a reduction housing 12 fixedly arranged on the upper side of the housing 10, the upper end of the valve core 23 is fixedly connected with a main shaft 21, the upper end of the main shaft 21 is provided with a worm wheel 22, the worm wheel 22 is meshed with a worm 14, and the outer end of the worm 14 extends out of the reduction housing 12 and is fixedly connected with a handle 13. When the valve body is required to be changed to be in a closed state, the handle 13 is screwed to enable the worm 14 to drive the worm wheel 22 to rotate, and then the main shaft 21 drives the valve core 23 to rotate, so that the on-off of a pipeline is completed.
Further, the driving module may be replaced by a solution in which the main shaft 21 is directly connected to a wrench, so as to cope with a pipeline with a smaller flow rate.
Further, the driving module can be replaced by other schemes for reducing speed and increasing torque, such as a planetary gear set or a gear set and other speed reducing schemes.
Further, a flange 11 is disposed at the water inlet and outlet of the housing 10.
The above examples are only illustrative of the preferred embodiments of the present utility model and do not limit the spirit and scope of the present utility model. Various modifications and improvements of the technical scheme of the present utility model will fall within the protection scope of the present utility model without departing from the design concept of the present utility model, and the technical content of the present utility model is fully described in the claims.
