[0022] See also Figure 1-4 The utility model provides a technical solution: a two-way sealed ball valve, comprising: a shell 1 and a ball body 5, a sealing groove 2 is opened inside the shell 1, and circular grooves 201 are opened at equal distances on both sides of the inner wall of the sealing groove 2, and the number of the circular grooves 201 is four, and an extrusion component 3 is provided on both sides of the inner wall of the sealing groove 2, the extrusion component 3 includes a round rod 301, a spring 302 and an extrusion plate 303, and a sealing sheet body 4 is fixedly installed on one side of the extrusion plate 303, the surface of the sealing sheet body 4 is in contact with the surface of the ball body 5, a flow hole 1 501 is opened on the surface of the ball body 5, a flow hole 2 6 is opened inside the shell 1, and a control rod 7 is fixedly installed on the top of the ball body 5.

[0023] Specifically: When the device starts to be used, the sealing sheet body 4 fixedly installed on one side of the extrusion plate 303 fits tightly with the spherical body 5, so that the device can have a good sealing effect when in use. The two extrusion components 3 set on the inner wall of the sealing groove 2 can maintain the sealing between the sealing sheet body 4 and the spherical body 5, so that the sealing between the sphere and the sealing sheet can also be maintained under long-term friction, making the device more perfect.

[0024] In one embodiment, one end of the round rod 301 is movably embedded in the inner wall of the circular groove 201, and there are four round rods 301. The inner wall of the spring 302 is movably sleeved on the surface of the round rod 301. The other side of the extrusion plate 303 is fixedly installed on the other end of the round rod 301. One end of the extrusion plate 303 is fixedly installed on one side of the inner wall of the sealing groove 2, and the other end of the extrusion plate 303 is fixedly installed on the other side of the extrusion plate 303.

[0025] Specifically: the two ends of the spring 302 are respectively fixedly mounted on one side of the inner wall of the sealing groove 2 and the other side of the extrusion plate 303. The elasticity of the spring 302 allows the extrusion plate 303 to always provide an extrusion force to the sealing sheet body 4, so that the sealing sheet body 4 is squeezed on the surface of the spherical body 5, so that the sealing effect between the sealing sheet body 4 and the spherical body 5 can be maintained. One end of the round rod 301 is movably embedded in the inner wall of the circular groove 201, and the other end of the round rod 301 is fixedly mounted on the other side of the extrusion plate 303. The spring 302 is sleeved on the surface of the round rod 301, so that the force generated by the elasticity of the spring 302 can be better provided to the extrusion plate 303, so that the device can maintain its good sealing effect during long-term use, making the device more perfect.

[0026] In one embodiment, a sealing gasket 8 is fixedly mounted on the surface of the control rod 7 . The surface of the sealing gasket 8 is mounted inside the housing 1 . A handle 9 is fixedly mounted on the top of the control rod 7 .

[0027] Specifically: the sealing gasket 8 fixedly sleeved on the surface of the control rod 7 is installed inside the housing 1. The sealing gasket 8 improves the sealing effect of the device so that the liquid will not leak through the gap between the control rod 7 and the housing 1 during circulation, making the device more perfect.

[0028] In one embodiment, channels 10 are fixedly installed at both ends of the shell 1, a diverter block 11 is fixedly installed at the other end of the channel 10, and a connector 12 is fixedly installed at an equal distance on the other side of the diverter block 11, and each connector 12 is of a different size. A limiting block 13 is fixedly provided on the surface of the connector 12, and a sealing cap 14 is provided on the surface of the connector 12.

[0029] Specifically: when the device is connected to the pipeline, the liquid flowing through the channel 10 is diverted to each connector 12 according to the diversion block 11. Since the size of each connector 12 is different, the corresponding connection port is found by comparing the pipeline with the connector 12, and the connection position of the connector 12 is exposed by unscrewing the sealing cap 14, so that the pipeline and the connector 12 are connected, and the liquid can flow into the pipeline through the connector 12. The sealing caps 14 on the surfaces of other connectors 12 are not unscrewed, and the liquid will not flow out. Therefore, the device can select different connection ports according to the size of the pipeline, making the device more perfect.

[0030] In one embodiment, a block 15 is fixedly installed on the top of the shell 1, and a limiting groove 16 is opened on the surface of the block 15. A fixed block 17 is fixedly installed on one end of the handle 9, and a limiting rod 18 is fixedly installed on the bottom of the fixed block 17. The surface of the bottom of the limiting rod 18 is movably installed on the inner wall of the limiting groove 16.

[0031] Specifically: the limiting rod 18 fixedly installed at the bottom of the fixing block 17 moves in the inner wall of the limiting groove 16 opened at the top of the block 15, so that the rotation of the handle 9 is restricted, so that the handle 9 will not rotate excessively to cause leakage of the device, making the device more perfect.

[0032] Working principle: When the device starts to be used, the sealing gasket 8 fixedly mounted on the surface of the control rod 7 is installed inside the shell 1, and the sealing effect of the device is improved by the sealing gasket 8, so that the liquid will not leak through the gap between the control rod 7 and the shell 1 when it circulates. The ball body 5 can be controlled to rotate by rotating the handle 9. When the flow hole 1 501 is connected with the flow hole 2 6, the device is equivalent to being opened, and when the flow hole 1 501 is hidden, the device is closed. During the use of the ball valve, the two ends of the spring 302 are respectively fixed on one side of the inner wall of the sealing groove 2 and the other side of the extrusion plate 303. The elasticity of the spring 302 makes the extrusion plate 303 always provide an extrusion force to the sealing piece body 4, so that the sealing piece body 4 is squeezed on the surface of the ball body 5, so that the sealing effect between the sealing piece body 4 and the ball body 5 can be maintained all the time, and one end of the round rod 301 is movably embedded in the round groove 201. The other end of the round rod 301 is fixedly mounted on the inner wall, and the other end of the round rod 301 is fixedly mounted on the other side of the extrusion plate 303. The spring 302 is sleeved on the surface of the round rod 301, so that the force generated by the elasticity of the spring 302 can be better provided to the extrusion plate 303, so that the device can maintain its good sealing effect during long-term use, making the device more perfect; when the pipeline is connected to the device, the liquid flowing through the channel 10 is diverted to each connector 12 according to the diverter block 11. Since the size of each connector 12 is different, the corresponding connection port is found by comparing the pipeline with the connector 12, and the connection position of the connector 12 is revealed by unscrewing the sealing cap 14, so that the pipeline and the connector 12 are connected, so that the liquid can flow into the pipeline through the connector 12. The sealing caps 14 on the surfaces of the other connectors 12 are not unscrewed, and the liquid will not flow out, so that the device can select different connection ports according to the size of the pipeline, making the device more perfect.
