Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a wear-resistant ceramic sealed Y-type three-way ball valve. Background Art

[0002] The three-way ball valve is a connection component used for diverting and merging materials. It is often used in the working process of various industrial equipment. In industrial or civil infrastructure, pipelines are usually used to transport media. Due to changes in pressure or temperature, the pipeline needs to be adjusted. In order to adjust the flow, an adjusting mechanism, especially a ball valve, is used in the pipeline to ensure optimal working conditions and environmental safety.

[0003] Currently, Chinese patent publication number CN 213017875 U discloses a three-way ceramic ball valve comprising a valve body, a feed pipe and two discharge pipes for conveying materials, a plug installed within the valve body, and both the discharge pipe and the feed pipe comprising an outer sleeve and an inner sleeve, the inner sleeve being disposed within the outer sleeve and extending through the valve body's outer shell into the valve body. The plug is mounted within the valve body and defines an arcuate flow channel that can be rotated to a set position to connect the feed pipe and either discharge pipe. The outer sleeve is made of metal, the inner sleeve is made of ceramic, and the outer surface of the plug and the arcuate flow channel are coated with a wear-resistant non-metallic material layer. Using this three-way valve structure, the valve body pipes will not chemically react with lithium battery positive and negative electrode material powders, preventing metal contamination of the positive and negative electrode materials. The valve can be used to convey lithium battery positive and negative electrode material powders.

[0004] This patent has the following problems:

[0005] 1. Small angle turns in the pipeline can easily cause the granular medium to wear and break, affecting the integrity of the medium particle size;

[0006] 2. After long-term use, dirt is likely to accumulate between the valve body and the plug. If it cannot be discharged in time, it will affect the normal use of the valve and the purity of the medium. Utility Model Content

[0029] The present invention will be described in further detail below with reference to the accompanying drawings.

[0030] Example 1: This embodiment discloses a wear-resistant ceramic sealed Y-type three-way ball valve. Figure 1 and 2As shown, it includes a ball valve body 1 and an upper valve cover 2 fixedly connected to the ball valve body 1, a ball valve cavity 11 and a ceramic ball 3 located in the ball valve cavity 11 are provided on the ball valve body 1, an arc-shaped ball channel 31 is provided in the ceramic ball 3, and a feed flange joint 12, a first diverter flange joint 13 and a second diverter flange joint 14 are provided on the ball valve body 1, which are connected to the ball valve cavity 11. The head 14 is respectively fixedly connected with a matching feed elbow 4, a first diversion elbow 5 and a second diversion elbow 6. The feed elbow 4, the first diversion elbow 5 and the second diversion elbow 6 are all arranged in an arc-shaped structure. The feed elbow 4, the first diversion elbow 5 and the second diversion elbow 6 are all fixedly connected with an arc-shaped ceramic liner 7. One end of the inner side of the ceramic liner 7 is provided with a ceramic valve seat 71 integral with it. The ceramic valve seat 71, the ceramic liner 7 and the ceramic ball 3 are all made of ceramic material. The liner 7, ceramic valve seat 71 and ceramic ball 3 can isolate the medium fluid from contacting the metal valve wall of the valve, ensuring the purity of the medium fluid and the reliability of materials that are sensitive to metals such as food raw materials and new energy battery powder. An arc-shaped liner channel is opened in the ceramic liner, and the liner channel forms an inlet channel 72, a first diversion channel 73 and a second diversion channel 74 in the feed elbow 4, the first diversion elbow 5 and the second diversion elbow 6 respectively, and the angle between the inlet channel 72 and the first diversion channel 73 or the second diversion channel 74 is set to 135 degrees. The large angle can divert the medium fluid, which can greatly reduce the erosion and wear of the valve internals by the medium, and at the same time prevent the granular medium from being broken due to small angle turns in the medium fluid channel, thereby protecting the particle size integrity of the medium. An actuator 8 compatible with it is provided on the upper valve cover 2, and an upper valve stem 32 compatible with it is provided at the lower end of the actuator 8. The upper valve stem 32 passes through the upper valve cover 2 and is fixedly connected to the upper end of the ceramic ball 3.

[0031] like Figure 1 and 2 As shown, the feed bend 4, the first diversion bend 5 and the second diversion bend 6 have the same structural arrangement, and an integrated bend flange joint 41 is arranged on the inner side of the feed bend 4, and the bend flange joint 41 is fixedly connected to the feed flange joint 12, the first diversion flange joint 13 and the second diversion flange joint 14 respectively by setting mounting bolts 411. The bend flange joint 41 is also provided with an integrated bend connection part 42, and the bend connection part 42 is bent and passed through the feed flange joint 12 or the first diversion flange joint 13 or the second diversion flange joint 14. The bend connection part 42 is also provided with a pressing groove 421 adapted to the ceramic valve seat 71, and the pressing groove 421 plays a limiting role on the ceramic valve seat 71. The bend connection part 42 facilitates the fixed connection between the feed bend 4, the first diversion bend 5 and the second diversion bend 6 and the ball valve body 1, ensuring that the ceramic lining and the ceramic valve seat 71 are installed in place.

[0032] like Figure 1 As shown, a first sealing ring 21 and a second sealing ring 321 are provided at the connection between the upper valve cover 2 and the upper valve stem 32, and a first sealing groove 22 and a second sealing groove 322 that are compatible with the first sealing ring 21 and the second sealing ring 321 are respectively provided on the upper valve cover 2 and the valve stem. The first sealing ring 21 and the second sealing ring 321 improve the sealing performance of the upper valve stem 32.

[0033] like Figure 1 As shown, a rotating boss 15 adapted to the ceramic sphere 3 is provided at the bottom of the ball valve chamber 11, and a lower rotating groove 151 is provided on the rotating boss 15. A lower valve stem 33 fixedly connected to the lower end of the ceramic sphere 3 is passed through the lower rotating groove 151. The lower valve stem 33 is also sleeved with a third sealing ring 331 adapted to the lower rotating groove 151, and a third sealing groove 332 adapted to the third sealing ring 331 is provided on the lower valve stem 33. The lower rotating groove 151 facilitates the rotation of the lower valve stem 33 and the ceramic sphere 3, and the rotating boss 15 facilitates the cleaning of the interior of the ball valve chamber 11.

[0034] like Figure 2 As shown, the lower part of the ball valve body 1 is provided with two drain holes connected to the ball valve cavity 11, and the drain holes are penetrated by drain bolts 34 threadedly connected thereto, and the drain bolts 34 are sleeved with sealing gaskets 35 adapted to the drain holes. The two drain bolts 34 cooperate with each other to facilitate cleaning of dirt accumulated in the valve, and the sealing gaskets 35 improve the sealing performance between the drain bolts 34 and the drain holes.

[0035] The working process is as follows:

[0036] The actuator 8 drives the ceramic ball 31 to rotate forward and reverse by 35 degrees, so that the ball channel 31 connects the feed channel and the first diversion channel 73 or connects the feed channel and the second diversion channel 74. The valve switches the discharge mode between the first diversion channel 73 and the second diversion channel 74. When the ceramic ball 3 rotates, the feed channel is blocked by it, and the valve is in a closed state.

[0037] In the sewage discharge mode, when the staff cleans the dirt accumulated in the ball valve, the actuator 8 is actuated to put the ceramic ball 3 in a diversion state, that is, one end of the ball channel 31 is connected to the feed channel, and the other end is connected to the first diversion channel 73 or the second diversion channel 74. At this time, a sealed space is formed between the ceramic ball 3, the ball valve body 1, and the upper valve cover 2. Then, the two sewage discharge bolts 34 are unscrewed, and cleaning liquid is poured into any one of the two sewage discharge holes. The accumulated dirt will be discharged from the other sewage discharge hole along with the cleaning liquid, thereby achieving the effect of cleaning the valve dirt.

[0038] Example 2: This example is based on Example 1. Figure 3As shown, the feed flange joint 12, the first diverter flange joint 13 and the second diverter flange joint 14 are provided with a connecting protrusion 121 adapted to the elbow flange joint 41, and the elbow flange joint 41 is provided with a connecting groove 412 adapted to the connecting protrusion 121. The inner wall of the connecting groove 412 is embedded with a fourth sealing ring 413 adapted to the connecting protrusion 121. The elbow flange joint 41 is respectively connected to the feed flange joint 12, the first diverter flange joint 13 and the second diverter flange by installing bolts 411. The joints 14 are connected to each other, and a compression spring 414 and an adjusting nut 415 are also sleeved on the mounting bolt 411. The ceramic valve seat 71 of the ball valve will still wear out after long-term use, resulting in a gap between the ceramic valve seat 71 and the ceramic sphere 3. At this time, the adjusting nut 415 can be screwed to make the elbow flange joint 41 closer to the ball valve body 1, thereby pushing the elbow connection part toward the inside of the ball valve cavity 11, and then driving the ceramic valve seat 71 to move and re-fit the ceramic sphere 3, thereby extending the service life of the valve.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
