Description

Technical Field

[0001] The utility model provides a symmetrical ball valve, which relates to the technical field of ball valves. Background Art

[0002] Ball valve, the valve with the ball driven by the valve stem and rotating around the axis of the ball valve, can be used for fluid regulation and control. Ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It can be closed tightly with only a 90-degree rotation and a very small torque.

[0003] Existing ball valves generally only connect pipelines at both ends. If there are two pipelines, two ball valves are required to separately control the flow between the pipelines. If two sets of pipelines need to control the flow and closure at the same time, the use of two ball valves not only requires two operations to open and close the pipeline, which is time-consuming and labor-intensive, but also wastes the production cost and funds of the ball valves.

[0004] Therefore, it is necessary to provide a symmetrical ball valve that can simultaneously control the communication between two groups of pipelines. Utility Model Content

DETAILED DESCRIPTION

[0024] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0025] Example 1: A symmetrical ball valve, see Figure 1-Figure 5 As shown, it includes: a valve body 1, a joint 2, a valve ball 3 and a valve seat 4, two joints 2 are fixedly connected to both sides of the valve body 1 by welding, a valve seat 4 is embedded in each joint 2, and a valve ball 3 for controlling the flow of water is rotatably arranged on each of the two valve seats 4, and also includes: a valve stem 5, a handle 7 and a fastening screw 8, two valve stems 5 are rotatably arranged in the middle of the valve body 1, the two valve stems 5 are respectively clamped with the two valve balls 3, a handle 7 is rotatably arranged in the middle of the valve body 1, the handle 7 is sleeved with the two valve stems 5, and the valve body 1 and the two valve stems 5 are threadedly arranged with a fastening screw 8.

[0026] When it is necessary to regulate two groups of pipelines at the same time, first, the two ends of the two groups of pipelines are respectively sleeved and fixed on the joints 2, and then the two valve stems 5 are driven to rotate synchronously when the handle 7 is turned. The two valve stems 5 drive the two valve balls 3 to rotate 90 degrees between the valve seats 4 to control the two groups of pipelines to be connected or cut off at the same time.

[0027] Example 2: Based on Example 1, refer to Figure 4 and Figure 6As shown, it also includes: two protective shells 9 installed on the valve body 1 by bolt connection, a temperature-controlled water tank 11 is installed in the protective shell 9 by bolt connection, a temperature-controlled water tank 11 is connected and communicated with a temperature-regulating pipe 12, the temperature-regulating pipe 12 is laid in the protective shell 9, three exhaust pipes 13 are connected and communicated between the bottom of the protective shell 9 and the valve body 1, a controller 10 is installed on the protective shell 9 by bolt connection, and the controller 10 is electrically connected to the temperature-controlled water tank 11.

[0028] When the weather is hot, in order to prevent the valve body 1 from expanding, cracking and deforming due to thermal expansion and contraction, the controller 10 controls the temperature-controlled water tank 11 to perform cooling, so that the ice water in the temperature-controlled water tank 11 cools the air in the protective shell 9 when flowing through the thermostatic tube 12. At this time, the cold air in the protective shell 9 directly contacts the valve body 1 through the exhaust pipe 13, absorbs the heat from the valve body 1, and heats the valve body 1. When the weather is hot, in order to prevent the water in the valve body 1 from freezing and making it difficult for the valve ball 3 to rotate, the controller 10 controls the temperature-controlled water tank 11 to perform heating to conduct heat to the valve body 1.

[0029] See also Figure 4 and Figure 7 As shown, it also includes: a fixed block 14 sleeved on the joint 2 by bolt connection, two fixed rods 15 are fixedly connected on both sides of the fixed block 14 by welding, and a connecting plate 16 is fixedly connected to the two fixed rods 15 on the same side by welding. A clamping plate 18 for clamping and fixing the pipeline is slidably provided on the two fixed rods 15. The clamping plate 18 is arc-shaped to facilitate fitting the pipeline and increase friction. A pull rod 17 is fixedly connected to the side away from each other by welding. The pull rod 17 is slidably connected to the connecting plate 16. A reset spring 19 is wound around the pull rod 17. The reset spring 19 is arranged between the connecting plate 16 and the clamping plate 18. The reset spring 19 pushes the clamping plates 18 on both sides to slide toward the side close to each other.

[0030] When the pipeline needs to be connected to the valve body 1, first slide the pull rod 17 to the side away from each other. At this time, the return spring 19 is compressed and deformed by the force. Then, the pipeline is put on the joint 2, and the pull rod 17 is loosened. At this time, the return spring 19 pushes the clamping plate 18 to slide and reset along the fixing rod 15, so that the clamping plates 18 on both sides jointly clamp the pipeline on the joint 2.

[0031] See also Figure 1 , Figure 4 and Figure 7 As shown, two sealing rings 6 are sleeved on the valve stem 5; a rubber pad 20 is installed on the side of the two clamping plates 18 close to each other by bonding; and a filter screen 21 is embedded in the joint 2.

[0032] The sealing ring 6 can increase the sealing between the valve body 1 and the valve stem 5 to prevent water from seeping from the valve stem 5 to the handle 7 and outward due to excessive water pressure; the rubber pad 20 can enhance the friction between the clamping plate 18 and the pipeline, so that the pipeline is fixed on the joint 2 and is not easy to slip; the filter net 21 can block and intercept impurities in the flowing water.
