[0019] Please see Figure 1 A ball valve for dairy products includes a left valve body 1, a handle 2 on the left valve body 1, a right valve body 3 on the right end of the left valve body 1, an O-ring 4 on the right valve body 3 that contacts the left valve body 1, a sealing ring 5 on the right valve body 3 that contacts the left valve body 1, a filter screen 6 that is slidably connected inside the right valve body 3, an installation mechanism 7 on the right valve body 3, and a cleaning mechanism 8 on the filter screen 6.

[0020] Please see Figures 1-2 The installation mechanism 7 includes a fixing ring 71. The fixing ring 71 is fixedly connected inside the right valve body 3. A guide rod 72 is slidably connected inside the fixing ring 71. A retaining ring 73 is fixedly connected to the left end of the guide rod 72, and the retaining ring 73 is slidably connected to the right valve body 3. A supporting ring 74 is fixedly connected to the right end of the guide rod 72, and the supporting ring 74 is slidably connected to the right valve body 3. A spring 75 is provided on the outside of the guide rod 72. One end of the spring 75 is fixedly connected to the fixing ring 71, and the other end of the spring 75 is fixedly connected to the supporting ring 74. By setting the spring 75, the... The retaining ring 74 is pushed to the right and is slidably connected to the filter screen 6. The retaining ring 73 is fixedly connected to the insert block 76, which is slidably connected to the filter screen 6. By setting the insert block 76, the filter screen 6 is limited. The inside of the right valve body 3 is connected to the pressure ring 77 by threads. The pressure ring 77 contacts the filter screen 6. The filter screen 6 filters the dairy fluid passing through the device, and the retaining ring 74 is supported by the spring 75. The pressure ring 77 and the right valve body 3 cooperate to limit the filter screen 6, thereby making it easy to disassemble and replace the filter screen 6.

[0021] Please see Figures 1-3The cleaning mechanism 8 includes a support shaft 81. The support shaft 81 is mounted inside the filter screen 6 via bearings. A blade 82 is fixedly connected to the surface of the support shaft 81. A square rod 83 is fixedly connected to the surface of the support shaft 81. A stop block 84 is fixedly connected to the right end of the square rod 83. A slip ring 85 is slidably connected to the outside of the square rod 83. A compression spring 86 is provided on the outside of the square rod 83. One end of the compression spring 86 is fixedly connected to the stop block 84, and the other end of the compression spring 86 is fixedly connected to the slip ring 85. By setting the compression spring 86, the slip ring 85 is elastically compressed. A scraper 87 is fixedly connected to the surface of the slip ring 85. The scraper 87 is slidably connected to the filter screen 6. By setting the scraper 87, the filter screen 6 is scraped. The dairy fluid drives the blade 82 to rotate the support shaft 81, which in turn causes the square rod 83 to rotate the slip ring 85, which in turn causes the scraper 87 to rotate and scrape the surface of the filter screen 6. This makes it easier to clean the impurities attached to the filter screen 6, avoids clogging of the filter screen 6 after long-term use, and improves the service life of the filter screen 6.

[0022] The specific implementation process of this utility model is as follows: When installing the filter screen 6, slide the filter screen 6 into the right valve body 3, and insert the block 76 on the support ring 74 into the filter screen 6. Manually rotate the pressure ring 77. The pressure ring 77 rotates and the right valve body 3 makes a threaded movement, thereby causing the pressure ring 77 to move to the left, which in turn causes the filter screen 6 to be squeezed to the left. This causes the support ring 74 to move and squeeze the spring 75. The dairy fluid passing through the device is filtered through the filter screen 6, and the support ring 74 is supported by the spring 75. The pressure ring 77 and the right valve body 3 cooperate to limit the position of the filter screen 6, thereby making the device easy to disassemble and replace the filter screen 6. When the device is in use, the dairy fluid driving blade 82 drives the support shaft 81 to rotate, thereby causing the filter screen 6 to move to the left. The square rod 83 drives the slip ring 85 to rotate, which in turn causes the scraper 87 to rotate and scrape the surface of the filter screen 6, making it easier to clean the impurities attached to the filter screen 6, preventing the filter screen 6 from clogging after long-term use, and improving the service life of the filter screen 6. By setting the left valve body 1 and the right valve body 3 in cooperation, unlike the traditional one-piece or multi-bolt connected valve bodies, the operator can separate the valve bodies without the need for complicated tools when cleaning or maintenance is required, which greatly improves maintenance efficiency. The flow channel is full-bore and optimized. The internal flow channel of the valve body is designed as a full-bore structure, and the flow channel profile has been optimized by precise fluid dynamics simulation. When the medium flows through the valve, there is almost no obstruction, and the flow resistance is reduced compared to ordinary dairy ball valves. By setting the O-ring 4 and the sealing ring 5 in cooperation, and using high-performance sealing materials such as food-grade silicone rubber or polytetrafluoroethylene, it has excellent corrosion resistance and temperature resistance, and can effectively resist the erosion of various components in dairy products.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
