The rotating rod 11 passes through the positioning column 8 and is inserted into the stirring assembly 10 to limit the position of the stirring assembly 10. The bottom end of the valve stem 2 is inserted into the top end of the valve disc 7 to limit the valve disc 7. At the same time, the bottom end of the valve stem 2 is wrapped around the top end of the rotating rod 11, and the rotating rod 11 is coaxially arranged with the valve stem 2. Finally, the sealing member 5 is used to seal the valve disc 7. The positioning column 8 and the rotating rod 11 are fixed, and the motor 6 is connected to the rotating rod 11 and installed on the sealing member 5. When in use, the discharge port of the valve body 1 is closed by rotating the valve stem 2, so that the medium inside the valve body 1 stops moving and is stored inside the valve body 1. The motor 6 is started to drive the rotating rod 11 to rotate, so that the rotating rod 11 drives the stirring assembly 10 to stir the medium inside the valve body 1, thereby reducing the solidification speed of the medium. At the same time, the stirring assembly 10 drives the cleaning assembly 9 to rotate along the inner side of the valve body 1, so that the cleaning assembly 9 scrapes off the medium solidified on the inner wall of the valve body 1.

[0038] Example 2

[0039] like Figure 1-2 As shown, the utility model proposes an eccentric hemispherical valve for easily solidifying media. Compared with Example 1, in this embodiment, a flange 4 is provided at the top end of the valve body 1, a stopper 3 is sealingly installed on the flange 4, and the valve stem 2 is installed in the middle of the stopper 3 and extends to the inner side of the valve body 1 to be connected with the valve disc 7 and the rotating rod 11.

[0040] In this embodiment, the flange 4 is used to increase the use interface of the valve body 1, so that the installation convenience of the inner structure of the valve body 1 is improved. At the same time, the middle part of the flange 4 is blocked by the block 3 to limit the opening size of the flange 4, and the flange 4 is sealed to the block 3. The bottom end of the valve stem 2 is extended into the valve body 1 and inserted into the top end of the valve flap 7 to install the valve flap 7.

[0041] Example 3

[0042] like Figure 2-4 As shown, the utility model proposes an eccentric hemispherical valve for easily solidifying media. Compared with the first embodiment, in this embodiment, the cleaning assembly 9 includes a scraper 91, an auxiliary scraper a92 and an auxiliary scraper b94;

[0043] The scraper 91 and the auxiliary scraper a92 are both arc-shaped, and there are two auxiliary scrapers a92. The two auxiliary scrapers a92 are symmetrically arranged on both sides of the scraper 91, and multiple ribs 93 are provided between the scraper 91 and the auxiliary scraper a92 to strengthen the installation stability. Among them, the valve flap 7 has two use parts, the first use part is a C-shaped block connecting the valve stem 2 and the positioning column 8, and the second use part is a sealing block in contact with the valve body 1. The two auxiliary scrapers a92 are provided on both sides of the scraper 91 for scraping the medium from the inner wall of the valve body 1 on both sides of the first use part of the valve flap 7 when the size on both sides of the first use part of the valve flap 7 is larger than the second use part.

[0044] There are multiple auxiliary scrapers b94, which are respectively arranged on the end side of the auxiliary scraper a92, and are used to scrape the medium from the inner wall of the valve body 1 in the upper and lower directions of the second use part of the valve flap 7 when the size of the first use part of the valve flap 7 is larger than the second use part.

[0045] In this embodiment, the scraper 91 is driven by the stirring assembly 10 to move along the inner wall of the valve body 1, so as to clean the solidified medium on the inner wall of the valve body 1. Since the valve flap 7 opens and closes the valve body 1 on the inner side of the valve body 1, when cleaning the inner wall of the valve body 1, the scraper 91 drives the auxiliary scraper a92 to clean the inner wall of the valve body 1 on both sides of the valve flap 7, and the auxiliary scraper b94 cleans the inner wall of the valve body 1 in the upper and lower directions of the valve flap 7, so that the cleaning of the inside of the valve body 1 is more convenient.

[0049] There are multiple stirring rods 102, which are arranged at equal distances on the side of the sleeve 101 and connected to the cleaning component 9, wherein the end projection shape of the stirring rod 102 is diamond-shaped, which is used to stir the medium of the valve body 1 through the corners when in use, so that the medium inside the valve body 1 moves through the inclined surface of the sleeve 101 and turns over the medium in the valve body 1, lowering the valve disc 7 to close the discharge port of the valve body 1 so that the internal contact causes solidification.

[0050] In an optional embodiment, the rotating rod 11 includes a rotating section 111 , a connecting section 112 and a transmission section 113 arranged coaxially. The rotating section 111 is inserted into the bottom end of the valve stem 2 , and the transmission section 113 is connected to the output shaft of the motor 6 .

When the stirring assembly 10 and the rotating rod 11 are in a state of cooperative installation, the connecting section 112 is cooperatively accommodated in the sleeve 101. In order to avoid the rotating section 111 from obstructing the connection between the sleeve 101 and the connecting section 112, the diameter of the transmission section 113 is set to be larger than the diameter of the rotating section 111. When the transmission section 113 drives the connecting section 112 and the rotating section 111 to pass through the positioning column 8 to move toward the inside of the valve body 1, the rotating section 111 can pass through the middle of the sleeve 101 without hindrance and connect with the valve stem 2. At the same time, the connecting section 112 is cooperatively connected with the sleeve 101, so that the position of the sleeve 101 on the connecting section 112 is limited by the shape of the connecting section 112.

[0052] To sum up, in the present invention, the cleaning assembly 9, the stirring assembly 10 and the valve disc 7 are placed in the middle of the valve body 1 at the same time through the cooperation of the inlet and outlet of the valve body 1 and the flange 4, and are rotated on the valve body 1, the stopper 3 is installed in the middle of the flange 4 to limit the opening size of the flange 4, the flange 4 is sealed and connected to the stopper 3, and the bottom end of the valve stem 2 is extended into the valve body 1 and inserted into the top end of the valve disc 7, the positioning column 8 is installed at the bottom end of the valve body 1 and inserted into the bottom end of the valve disc 7, so that the valve disc 7 is installed and fixed, making the installation of the valve disc 7 and the cleaning assembly 9 more convenient, the transmission section 113 drives the connecting section 112 and the rotating section 111 to move toward the inside of the valve body 1 through the positioning column 8, so that the transmission section 113 drives the rotating section 111 and the connecting section 112 to pass through the positioning column 8 and be inserted into the sleeve 101 and the bottom end of the valve stem 2, and the sleeve 101 is limited to the inner part of the valve disc 7 by the shape of the connecting section 112. On the other hand, the cleaning component 9 is installed on the inner side of the valve body 1 through the stirring rod 102. When in use, the valve disc 7 is rotated to close the discharge port of the valve body 1 through the rotation of the valve stem 2, so that the medium inside the valve body 1 stops moving and is stored inside the valve body 1. The motor 6 is started to drive the transmission section 113 to rotate, so that the transmission section 113 drives the stirring rod 102 to stir the medium inside the valve body 1 through the interconnected connecting section 112 and the sleeve 101, thereby reducing the solidification speed of the medium. At the same time, the stirring rod 102 drives the scraper 91 to rotate along the inner side of the valve body 1, so that the scraper 91 scrapes off the medium solidified on the inner wall of the valve body 1. At the same time, due to the structural shape of the valve disc 7, when cleaning the inner wall of the valve body 1, the scraper 91 drives the auxiliary scraper a92 to clean the inner wall of the valve body 1 on both sides of the valve disc 7, and the auxiliary scraper b94 cleans the inner wall of the valve body 1 in the upper and lower directions of the valve disc 7, so that the cleaning of the inside of the valve body 1 is more convenient and more thorough.
