The valve body cylinder (13) has an inwardly protruding valve body limit platform (19) on the upper inner wall of the valve body guide cavity (18). The upper part of the valve body limit platform (19) is a valve body sealing cavity (17) corresponding to the valve core sealing ring (3) when the sewage valve is in a closed state. ), the cross-sectional area of ​​the valve body inner cavity (14) portion at the upper part of the valve body sealing cavity (17) is larger than the cross-sectional area of ​​the valve core cylinder (9), and the top of the valve body sealing cavity (17) and the valve body inner cavity (14) portion at the upper part of the valve body sealing cavity (17) are connected via a valve body fixed limiting flange (20), the valve body cylinder (13) is provided with a valve body water inlet (16) at the connection with the valve body fixed limiting flange (20), the height of the valve body sealing cavity (17) is smaller than the distance between the valve core sealing ring (3) and the valve core guide limiting block (4), the lower side of the valve body fixed limiting flange (20) is provided with a valve body sealing ring (22) at the connection with the valve body fixed threaded sleeve (21), the cross-sectional area of ​​the valve body fixed threaded sleeve (21) is equivalent to the opening on the breeding container, and also includes a valve body fastening lock nut (23) matched with the valve body fixed threaded sleeve (21).

[0008] Preferably, the valve core guide columns (1) are two evenly distributed along the circumference of the outer wall of the valve core, respectively corresponding to two symmetrical valve body annular guide grooves (10).

[0009] Preferably, the portion of the valve core cylinder (9) connected to the upper side of the valve core guide limit block (4) is an elastic valve core spring sheet (6) that can be bent inwards.

[0010] Preferably, the valve body annular guide groove (10) is a rotating rising platform on the inner wall of the valve body cylinder (13), one end of which is a high point platform (11) and the other end of which is a low point platform (12), and valve body guide groove limit columns (24) are respectively provided at the high point platform and the low point platform.

[0013] Further preferably, the upper part of the body of the wire mesh cylinder (A3) has a wire mesh cylinder overflow port (26).

[0014] Preferably, the outer wall of the valve core cylinder (9) has a plurality of protruding valve core positioning columns (2).

[0015] The technical effects of the present invention are as follows:

[0016] When the sewage valve of the present invention is in use, the valve body fixing threaded sleeve passes through the bottom plate hole of the breeding container, so that the valve body fixing limiting flange is attached to the bottom plate passing through the breeding container and is locked by the valve body fastening lock nut, and the valve body sealing ring is attached to the bottom plate of the breeding container to form a seal.

[0017] The valve core is installed in the valve body, and can be deformed inwards through the valve core spring sheet, so that the valve core guide limit block passes through the valve body limit platform, the valve core sealing ring enters the valve body sealing cavity, the valve core guide column fits with the bottom end of the valve body annular guide groove, and the valve is in a closed state. When water enters the breeding container, a driving force is formed by the liquid level difference between the water level and the valve core overflow port, forcing water to pass through the valve body water inlet, through the cavity waterway between the valve core and the valve body, flow upward, enter the valve core cavity through the valve core overflow port, and be discharged from the breeding container by gravity, thereby realizing the renewal of water in the breeding container, and impurities in the water will also be discharged with the water flow. When the breeding tank stops taking in water, the water level is maintained at the height of the valve core overflow port;

[0018] When the valve core rotates upward from the bottom end to the upper end of the valve body annular guide groove along the valve body, the valve core guide column will interact with the valve body annular guide groove to generate an upward thrust, driving the valve core to rotate and move upward. When it reaches the upper end of the valve body annular guide groove, the valve core guide column is limited by the valve body guide groove limit column, and the valve core guide limit block is limited by the valve body limit platform. The valve core cannot continue to rotate in this direction, nor will it fall, nor will it continue to move upward and separate from the valve body. At the same time, since the height of the valve body sealing cavity is less than the distance between the valve core sealing ring and the valve core guide limit block, the valve core sealing ring and the valve core drain port are forced to separate upward from the valve body sealing cavity, so that the valve body water inlet is connected to the valve core inner cavity through the valve core drain port, the valve is opened, and water is directly discharged from the bottom.

[0019] When the valve core rotates along the valve body annular guide groove from the upper end of the valve body annular guide groove to the lower end of the valve body annular guide groove, the valve core guide column will interact with the valve body annular guide groove, press the valve core, generate a downward thrust, and force the valve core to rotate and move downward. When it reaches the lower end of the valve body annular guide groove, the valve core guide column is limited by the valve body guide groove limit column, and cannot continue to rotate in this direction, nor will it fall. At the same time, the valve core sealing ring and the valve core drain port are forced to enter the valve body sealing cavity downward, so that the valve body water inlet is disconnected from the valve core drain port, and the valve is closed.

[0020] Preferably, the valve core positioning column acts on the inner cavity of the valve body, and the valve core always remains concentric with the valve body during the process of the valve core being installed into the valve body and the process of the valve core moving up and down.

[0021] Preferably, the overflow port of the valve core, the overflow port of the valve body, and the overflow port of the net tube are interconnected. When the waterway is blocked, the water in the breeding tank can directly enter the inner cavity of the valve core through the overflow port and be discharged.

[0022] Preferably, a wire mesh tube is further used on the outside to prevent the cultured aquatic organisms from escaping.

[0023] The self-purifying sewage valve of the present invention is used for removing excrement and food in the breeding of fish and aquatic organisms to meet the water cleanliness and provide a good living environment for fish and aquatic organisms. Under the condition that no external valve is required, the functions of upper overflow and bottom discharge are realized by switching the valve core position. At the same time, the two processes share the waterway and there is no dead corner for water and sediment. While improving the efficiency of water renewal for aquatic organisms such as fish, the connecting pipeline is greatly simplified, the factors of water pollution are reduced, and the operability is improved.

Figure 5 , 6 It can be seen that the valve core guide pillars 1 are two evenly distributed along the circumference of the outer wall of the valve core, respectively corresponding to two symmetrical valve body annular guide grooves 10. The rotating rising platform on the inner wall of the valve body cylinder 13 has one end higher than the other end, one end is a high point platform 11, and the other end is a low point platform 12. The high point platform 11 and the low point platform 12 are respectively provided with valve body guide groove limit pillars 24. The valve core guide column 1 can move up and down along the valve body annular guide groove 10 to drive the valve core A1 to move up and down when the valve core A1 rotates.

The valve body cylinder 13 has an inwardly protruding valve body limit platform 19 on the upper inner wall of the valve body guide cavity 18. The upper part of the valve body limit platform 19 is a valve body sealing cavity 17 corresponding to the valve core sealing ring 3 when the sewage valve is in the closed state.

When it reaches the upper end of the valve body annular guide groove, the valve core guide column is limited by the valve body guide groove limit column, and the valve core guide limit block is limited by the valve body limit platform. The valve core cannot continue to rotate in this direction, nor will it fall, nor will it continue to move upward and separate from the valve body. At the same time, since the height of the valve body sealing cavity is less than the distance between the valve core sealing ring and the valve core guide limit block, the valve core sealing ring and the valve core drain port are forced to separate upward from the valve body sealing cavity, so that the valve body water inlet is connected to the valve core inner cavity through the valve core drain port, the valve is opened, and water is directly discharged from the bottom.

[0045] When the valve core rotates along the valve body annular guide groove from the upper end of the valve body annular guide groove to the lower end of the valve body annular guide groove, the valve core guide column will interact with the valve body annular guide groove, press the valve core, generate a downward thrust, and force the valve core to rotate and move downward.
