Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

As shown in fig. 1-6, a reversing T-shaped three-way ball valve includes a valve body 1, a valve cover 2, a valve core 3 and a valve rod, the valve body 1 and the valve cover 2 are matched to form two medium inflow channels 5 and a medium outflow channel 6, valve seats 7 capable of being matched with the valve core 3 are arranged in the two medium inflow channels 5, and the valve core 3 is of a hemispherical structure and is driven by the valve rod to rotate. The sealing surface of the valve core 3 is a spherical surface, and the sealing surface can seal one valve seat 7 to completely seal one medium inflow channel 5, and can also be positioned between two medium inflow channels 5, so that the rotation of the valve core 3 can switch the flow direction, confluence and shunting functions.

The valve body 1 is provided with a mixing unit 8 used for changing the flowing state of fluid in the valve in the medium outflow channel 6, the mixing unit 8 comprises a fixing ring 9, the axis of the fixing ring 9 is provided with a through hole 10 communicated with the medium outflow channel 6, the through hole 10 is internally provided with a plurality of mixing assemblies 11 linearly distributed along the axis, a channel 12 for the mixed medium to flow through is arranged between each mixing assembly 11 and the fixing ring 9, and two adjacent channels 12 are arranged in a staggered mode.

When the three-way ball valve described in the present application is opened, the mixing unit 8 located in the medium outflow passage 6 can merge the media from the two medium inflow passages 5, thereby sufficiently mixing the two different medium fluids. Meanwhile, because the channels 12 on the adjacent mixing modules 11 are arranged in a staggered manner, after two medium fluids pass through the channel 12 of one mixing module 11, the two medium fluids need to be blocked by the other adjacent mixing module 11 to change the flowing state of the fluids, so that the purposes of good dispersion and full mixing of different fluids are achieved.

Further, the outer side of the fixing ring 9 is fixedly connected with the inner wall of the medium outflow channel 6, so that the axis of the fixing ring 9 is consistent with the axis of the medium outflow channel 6.

Further, each mixing component 11 comprises a first fixing rod 13, and both ends of the first fixing rod 13 are fixedly connected with the fixing ring 9. One side of the first fixing rod 13 is sleeved with a plurality of first rotating blocks 14 which are linearly arranged. When a plurality of transmission media pass through the mixing unit 11, the flow of the media causes the first rotating block 14 to rotate about the first fixing rod 13. Meanwhile, the rotating first rotating block 14 can guide various transmission media to flow, and the first rotating block 14 and the first fixing rod 13 rotate, so that the shearing force of the first rotating block 14 on the various transmission media can be reduced while the guiding media are mixed, and the device is suitable for transmitting high-molecular mixed media with long molecular chains.

Furthermore, each mixing assembly 11 further comprises a second fixing rod 15 perpendicular to the first fixing rod 13, and the second fixing rod 15 is integrally connected with the first fixing rod 13. Both ends of the second fixing rod 15 are fixedly connected with the fixing ring 9. One side of the second fixing rod 15 is sleeved with a plurality of second rotating blocks 16 which are linearly arranged. By additionally arranging the second rotating block 16 in each mixing assembly 11, the guiding and mixing effects on various transmission media can be enhanced, and the disturbing effect on the various transmission media can be increased, so that the flowing state of the fluid in the pipe can be further changed, and the purposes of good dispersion and full mixing among different fluids can be achieved.

Further, the first rotating block 14 and the second rotating block 16 are both spherical. Since the surface of the valve element 3 is smooth, there is no sharp projection. So that the first rotating block 14 and the second rotating block 16 have a low shearing effect on various transmission media when being in contact with the transmission media. Thereby being suitable for transmitting the macromolecular mixed medium with long molecular chains.

Further, the valve rod includes upper valve rod 4 and lower valve rod 17, and the upper and lower both ends of case 3 are connected with upper valve rod 4, lower valve rod 17 key respectively.

Furthermore, rotating bearings 18 are respectively arranged between the valve body 1 and the upper valve rod 4 and between the valve body 1 and the lower valve rod 17. By providing the rotary bearing 18, the valve element 3 has a high rotational stability in the valve body 1.

Further, one side of each valve seat 7 is provided with a hard seal 19 which can form a sealing fit with the valve element 3.

Furthermore, an elastic part 20, a pressing ring 21 and a graphite ring 22 are sequentially arranged between the valve cover 2 and the valve seat 7, one end of the elastic part 20 is connected with the valve body 1, and the other end of the elastic part 20 is connected with the pressing ring 21. The side of the pressing ring 21 facing the graphite ring 22 is provided with a V-shaped lug 23, and one side of the graphite ring 22 is provided with a V-shaped groove 24 which can be matched with the V-shaped lug 23. Under the action of the elastic member 20, the V-shaped protrusion 23 is tightly attached to the V-shaped groove 24.

By rotating the valve stem to rotate the valve element 3, the rotation of the valve element 3 is transmitted to the valve seat 7 through the mating hard seal 19, so that the valve seat 7 moves in the direction of compression of the elastic member 20. Thereby avoid the friction of transition between hard sealing member 19 and case 3, reduce under the condition of the wearing and tearing of hard sealing member 19 so that the valve rod drives case 3 and rotates for the valve rod low moment can drive case 3 and rotate. And the fit between the V-shaped lug 23 and the V-shaped groove 24 can make the fit between the V-shaped lug 23 and the graphite ring 22 more tight. The movement of the valve seat 7 can be transmitted to the elastic part 20 through the graphite ring 22 and the V-shaped lug 23 in sequence, the valve seat 7 can be ensured to be always in sealing fit with the valve core 3, and the sealing performance is good.

The working principle is as follows: the two medium inflow passages 5 are A, B, respectively, and the one medium outflow passage 6 is C. When the flow direction is switched, the valve core 3 is rotated, the sealing surface of the valve core 3 blocks the channel A or the channel B, and the other channel is communicated with the channel C. When the flow is mixed, the valve core 3 is rotated to enable the C channel to be communicated with the A, B channel respectively, and the flow mixing is realized. In the mixed flow state, the mixing unit 8 can change the flow state of different fluids in the valve, thereby leading to good dispersion and sufficient mixing between different media.
