DETAILED DESCRIPTION

[0042] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0043] like Figures 1 to 6As shown, a sewage discharge valve of the present invention comprises a valve body 1, a valve stem 2, a hand wheel 3, a pressing rod 4 and a storage cylinder 5; a water flow channel 11 is arranged in the valve body 1, a connector 12 is formed at the lower end of the water flow channel 11, an output port is formed in the connector 12, a valve port 13 is formed in the valve body 1, the valve port 13 is located in the water flow channel 11, and the valve port 13 is located directly above the output port; a blocking member 21 is arranged at the lower end of the valve stem 2, and the valve stem 2 can be raised and lowered in the valve body 1 so that the blocking member 21 blocks or does not block the valve port 13; an installation channel is formed in the valve stem 2; a hand wheel 3 is arranged at the upper end of the valve stem 2, and the hand wheel 3 is rotated to drive the valve stem 2 to rise or fall; the pressing rod 4 can be raised and lowered in the installation channel, a pressing head 41 which can be inserted into the storage cylinder 5 is formed at the lower end of the pressing rod 4, and the upper end of the pressing rod 4 is connected to the pressure wheel 42 after passing through the valve stem 2; the storage cylinder 5 is connected to the connector 12, a storage cavity is formed in the storage cylinder 5, and the storage cavity is located directly below the output port.

[0044] The present invention relates to a sewage discharge valve. After the sewage discharge valve is installed on the discharge pipe 9, force is applied to the hand wheel 3 to rotate the hand wheel 3. The hand wheel 3 rotates and drives the valve stem 2 to rise or fall. When it is necessary to close, the valve stem 2 falls, so that the blocking member 21 blocks the valve port 13, thereby closing the water flow channel 11. When it is necessary to open, the valve stem 2 rises, so that the blocking member 21 is away from the valve port 13, thereby opening the water flow channel 11. The overall operation is relatively simple. When debris is blocked at the valve port 13, the main valve is closed, and then the pressure wheel 42 is pressed to drive the pressing rod 4 to press down. The pressing rod 4 presses down and drives the pressing head 41 to press down, so that the pressing head 41 squeezes the debris at the valve port 13 and presses the debris into the storage tube 5 for storage. When the debris in the storage tube 5 is stored to a certain amount, the storage tube 5 is disassembled, the debris in the storage tube 5 is cleared, and then the storage tube 5 is reinstalled. Therefore, the present invention provides a pressing rod 4 to facilitate pressing the debris into the storage tube 5, making cleaning more convenient.

[0045] In the embodiment of the present invention, a water inlet connection end 14 is formed at one end of the valve body 1, and a water outlet connection end 15 is formed at the other end of the valve body 1. When installing the sewage discharge valve, the water inlet connection end 14 and the water outlet connection end 15 are locked and connected with the discharge pipe 9, thereby completing the installation of the sewage discharge valve.

[0046] In order to make the plugging member 21 conveniently and firmly connected to the valve stem 2, an anti-dropping convex ring 22 is formed at the end of the valve stem 2, and a locking member 23 is also included. The locking member 23 is sleeved on the valve stem 2, and an external thread is arranged on the outer side of the locking member 23. The lower end of the locking member 23 abuts against the upper side of the anti-dropping convex ring 22; a top step 211 abutting against the lower side of the anti-dropping convex ring 22 is formed in the plugging member 21, and an internal thread connected to the external thread is arranged in the plugging member 21. Among them, a positioning ring 231 is formed at the upper end of the locking member 23 for the plugging member 21 to abut.

[0047] When the valve stem 2 is connected to the plugging member 21, the locking member 23 is first sleeved on the valve stem 2, and then the plugging member 21 is rotated. Under the action of the internal thread and the external thread, the plugging member 21 and the locking member 23 are locked together. Since the upper side of the anti-slip convex ring 22 abuts against the locking member 23, and the lower side of the anti-slip convex ring 22 abuts against the abutting step 211, after the valve stem 2 and the plugging member 21 are connected, the plugging member 21 is difficult to be separated from the valve stem 2, and the plugging member 21 is firmly fixed on the valve stem 2. Specifically, when installing the plugging member 21, the positioning ring 231 on the locking member 23 can be pressed, and then the plugging member 21 can be rotated. When the end of the plugging member 21 abuts against the positioning ring 231, the installation of the plugging member 21 is completed, and the installation process is relatively simple.

[0048] like Figure 3 As shown, further, the pressing head 41 includes an upper connecting section 411, a middle connecting section 412 and a lower connecting section 413. The upper connecting section 411 can fit in the receiving groove 212, one end of the middle connecting section 412 is connected to the upper connecting section 411, and the lower connecting section 413 is connected to the other end of the middle connecting section 412. Among them, the outer diameter of the middle connecting section 412 is greater than the outer diameter of the upper connecting section 411, and the outer diameter of the middle connecting section 412 is greater than the outer diameter of the lower connecting section 413. By providing the upper connecting section 411, the upper connecting section 411 can fit in the receiving groove 212, thereby preventing sewage from flowing out of the installation channel.

[0049] In this embodiment, the outer diameter of the lower connecting section 413 gradually decreases from the direction close to the middle connecting section 412 to the direction away from the middle connecting section 412, and an outer connecting curved surface 4131 is formed on the outer side of the lower connecting section 413, and a hook 4132 facing the center is provided on the outer connecting curved surface 4131. After the debris blocks the valve port 13, the pressure wheel 42 is pressed to press the pressing head 41 downward. When the pressing head 41 is pressed downward, the hook 4132 can hook the debris, thereby facilitating the debris to be pressed into the storage tube 5.

[0050] Furthermore, a receiving groove 212 for receiving the upper part of the pressing head 41 is formed at the bottom of the plugging member 21, and a sealing ring 2121 is provided on the groove wall of the receiving groove 212. When the upper connecting section 411 is fitted into the receiving groove 212, the outer side of the upper connecting section 411 is tightly pressed against the sealing ring 2121, thereby improving the sealing effect and preventing sewage from flowing out of the installation channel. When sewage flows from the water channel 11, the pressing head 41 is subjected to the pressure of the sewage, and under the action of the sewage water pressure, the pressing head 41 realizes that the outer side of the upper connecting section 411 is tightly pressed against the sealing ring 2121.

[0051] In order to further make the outer side of the upper connecting section 411 tightly against the sealing ring 2121, a compression spring 24 is sleeved on the outer side of the valve stem 2, one end of the compression spring 24 rests on the hand wheel 3, and the other end of the compression spring 24 rests on the pressure wheel 42. The compression spring 24 is in a compressed state, and the pressure wheel 42 is acted upon by the compression spring 24, so that the pressing head 41 has a tendency to move upward, so that the outer side of the upper connecting section 411 tightly rests on the sealing ring 2121, further preventing sewage from flowing out of the installation channel.

[0052] In a preferred embodiment of the present invention, the storage cylinder 5 includes an upper cylinder 51, a lower cylinder 52 and an opening and closing door 53. The upper section of the upper cylinder 51 forms a connecting cylinder 511, the connecting cylinder 511 is connected to the connecting head 12, a material discharge port is formed in the connecting cylinder 511, the lower cylinder 52 is connected to the upper cylinder 51, and the opening and closing door 53 includes a door body 531 and a rebound assembly 532. The door body 531 includes a horizontal plate 5311 and a vertical plate 5312. The horizontal plate 5311 is recessed inward to form a pressure groove 53 111, the vertical plate 5312 and the horizontal plate 5311 are integrally formed, and a perforation is set on the vertical plate 5312. The rebound assembly 532 includes a positioning rod 5321, a connecting nut 5322 and a rebound spring 5323. The end of the positioning rod 5321 is fixed to the inner wall of the upper cylinder 51, and the positioning rod 5321 passes through the perforation and is connected to the connecting nut 5322. One end of the rebound spring 5323 is set on the vertical plate 5312, and the other end of the rebound spring 5323 is set on the upper cylinder The pressure groove 53111 includes a first pressure groove 53111a and a second pressure groove 53111b, the door body 531 includes a first door body 531a and a second door body 531b, the first door body 531a is provided with a first pressure groove 53111a, and the second door body 531b is provided with a second pressure groove 53111b, the rebound component 532 includes a first rebound component 532a and a second rebound component 532b, and the first rebound component 532a drives The first door body 531a is close to the second door body 531b, and the second rebound component 532b drives the second door body 531b to approach the first door body 531a. The first door body 531a and the second door body 531b are close to each other and lean against each other. The first pressure groove 53111a of the first door body 531a and the second pressure groove 53111b of the second door body 531b are leaned against each other to form a socket for inserting the pressing head 41, and the width of the socket is smaller than the width of the middle connecting section 412.

[0053] After the pressing head 41 is pressed down, the outer connecting curved surface 4131 of the pressing head 41 is inserted into the socket. Since the width of the socket is smaller than the width of the middle connecting section 412, the first door body 531a and the second door body 531b are moved away from each other under the action of the pressing head 41, thereby facilitating pressing the debris into the storage tube 5.

[0054] Since the storage cylinder 5 includes an upper cylinder 51 and a lower cylinder 52, the upper cylinder 51 can be threadedly connected to the connector 12, and the lower cylinder 52 can be threadedly connected to the upper cylinder 51, so that the lower cylinder 52 can be easily disassembled and the opening and closing door 53 can be easily installed. Among them, a close surface 121 is provided in the connector 12 to facilitate pressing the sundries into the storage cylinder 5. If there is no close surface 121, the sundries in the corners are not easy to be pressed into the storage cylinder 5.

[0055] The positioning rod 5321 and the connecting nut 5322 are provided to make the door body 531 move more smoothly. The first rebound assembly 532a and the second rebound assembly 532b are provided to facilitate the first door body 531a and the second door body 531b to be close to each other and lean against each other. After the first door body 531a and the second door body 531b lean against each other, the storage cavity in the storage tube 5 is connected to the water flow channel 11 through the socket, and the width of the socket is small, so that the phenomenon of debris escaping from the storage cavity can be effectively reduced.

[0056] Furthermore, a first sliding curved surface is formed on the upper surface of the first pressure groove 53111a, and a second sliding curved surface is formed on the lower surface of the first pressure groove 53111a. By providing the first sliding curved surface, after the pressing head 41 is pressed down, the outer connecting curved surface 4131 slides along the first sliding curved surface, so that the first door body 531a and the second door body 531b are separated from each other. After the sundries are pressed into the storage tube 5, the upper connecting section 411 moves along the second sliding curved surface, so that the first door body 531a and the second door body 531b are separated from each other, so that it is easy for the pressing head 41 to be separated from the storage tube 5.

[0057] In this embodiment, a limit rod 53121 is provided on the vertical plate 5312. The length of the limit rod 53121 is smaller than the length of the positioning rod 5321. The rebound spring 5323 is sleeved on the limit rod 53121. By providing the limit rod 53121, the rebound spring 5323 is not easily distorted when compressed.

The cylinder seat 741 is fixed on the outer wall of the sedimentation cylinder 7, and the cylinder 742 is arranged on the cylinder seat 741. One end of the horizontal connecting rod 743 is connected to the cylinder 742 and is driven by the cylinder 742. Lifting, the upper end of the lifting rod 744 is connected to the other end of the horizontal connecting rod 743 and is lifted and lowered synchronously with the horizontal connecting rod 743, the abutting plate 745 is fixedly connected to the lower end of the lifting rod 744, the bottom of the abutting plate 745 is set to abut against the inclined surface 733, the end of the rotating plate 746 can be rotatably connected to the abutting plate 745, one end of the elastic member 747 is connected to the abutting plate 745, and the other end of the elastic member 747 is connected to the bottom of the rotating plate 746, the outlet 748 is set at the side of the sedimentation cylinder 7, and the pressure block 749 is fixed to the inner wall of the sedimentation cylinder 7 and is located below the outlet 748; when the rotating plate 746 rises, the rotating plate 746 abuts on the pressure block 749, driving the rotating plate 746 to rotate along the abutting plate 745.
