[0002] The sewage valve evolved from the gate. It is a valve that controls the discharge of sewage by opening and closing the valve. The easy-to-install sewage valves currently on the market are easily accumulated at the pipe bends during actual use due to the soft impurities in the sewage. If this continues for a long time, it will cause pipe blockage, resulting in untimely sewage discharge. The valve is easily blocked due to the accumulation of debris, thus affecting the normal use of the valve. Utility Model Content

[0003] In order to overcome the above-mentioned defects, the utility model provides a sewage valve that is easy to install, which solves the problem that soft impurities in sewage are easily accumulated at the turning point of the pipeline, which will cause pipeline blockage in the long run, resulting in untimely sewage discharge, and the valve is easily blocked due to the accumulation of debris, thereby affecting the normal use of the valve.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sewage valve that is easy to install, comprising a first fixed ring, one side of the first fixed ring is fixedly connected to a connecting rod, an end of the connecting rod away from the first fixed ring is installed with a second fixed ring, one side of the first fixed ring is provided with a telescopic spring, one end of the telescopic spring is installed with a movable ring, the movable ring is movably connected to the connecting rod, the outer arc surface of the movable ring is provided with a groove, a movable wheel is installed in the groove, and a support column is fixedly connected inside the movable ring;

[0009] As a further solution of the utility model: a sealing ring is fixedly connected to one side of the input end, and a threaded rod is threadedly connected to the input end. The number of the threaded rods is four and they are distributed in a rectangular array.

[0010] As a further solution of the utility model: a toggle is fixedly connected to the threaded rod, and a clamping plate is installed under the threaded rod.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The easy-to-install sewage valve is equipped with a bidirectional motor, a propeller, a crushing rod and a crushing blade, so that the bidirectional motor can simultaneously drive the propeller, the crushing rod and the crushing blade to rotate through the output shaft, thereby crushing the impurities in the sewage, which not only reduces the volume of the impurities but also allows the sewage to continue to move when the valve is closed, thereby preventing the impurities in the sewage from accumulating in the valve and improving the anti-blocking effect of the valve.

[0013] 2. The easy-to-install sewage valve is provided with a connecting rod, a telescopic spring, a movable ring and a movable wheel. When the valve is opened, the water flow can impact the movable ring, so that the movable wheel outside the movable ring can drive the movable ring to move on the surface of the connecting rod. At the same time, the elastic force of the telescopic spring drives the movable wheel to move back and forth, thereby improving the crushing efficiency of the crushing rod and further improving the anti-blocking effect of the valve.

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a sewage valve that is easy to install, including a first fixing ring 1, the outer arc surface of the first fixing ring 1 is fixedly connected with a valve body 15, the inner wall of the valve body 15 is installed with a sealing seat 16, the sealing seat 16 is provided with a valve plate 17, the valve plate 17 is fixedly connected with a valve stem 18, the valve stem 18 is threadedly connected to the valve body 15, and a hand wheel 19 is installed at one end of the valve stem 18 away from the valve plate 17. By setting the valve plate 17, the valve plate 17 can control the discharge and stop of sewage by the valve;

[0021] An input end 20 is fixedly connected to one side of the valve body 15, and an output end 21 is arranged on the side of the valve body 15 away from the input end 20. A sealing ring 22 is fixedly connected to one side of the input end 20. A threaded rod 23 is threadedly connected to the input end 20. The number of the threaded rods 23 is four and they are distributed in a rectangular array. By arranging the sealing ring 22, after the pipeline is installed with the input end 20, the sealing ring 22 can play a role in sealing and leak-proofing the connection.

[0022] A twisting knob 24 is fixedly connected to the threaded rod 23, and a clamping plate 25 is installed under the threaded rod 23. By setting the twisting knob 24, the twisting knob 24 can drive the clamping plate 25 through the threaded rod 23 to clamp and limit the assembled pipe.

[0023] A connecting rod 2 is fixedly connected to one side of the first fixing ring 1, and a second fixing ring 4 is installed at one end of the connecting rod 2 away from the first fixing ring 1. A telescopic spring 3 is arranged on one side of the first fixing ring 1, and a movable ring 5 is installed at one end of the telescopic spring 3. The movable ring 5 is movably connected to the connecting rod 2. A groove 6 is provided on the outer arc surface of the movable ring 5, and a movable wheel 7 is installed in the groove 6. A support column 8 is fixedly connected to the inside of the movable ring 5. By setting the connecting rod 2, the connecting rod 2 can effectively limit the range of motion of the movable ring 5.

[0024] A bidirectional motor 9 is installed on the inner wall of the support column 8, a first connecting rod 10 is arranged at one end of the bidirectional motor 9 through a transmission shaft, a propeller 11 is fixedly connected to one end of the first connecting rod 10, a second connecting rod 12 is installed at the end of the bidirectional motor 9 away from the first connecting rod 10, a crushing rod 13 is fixedly connected to the outer arc surface of the second connecting rod 12, and a crushing blade 14 is installed on the outer arc surface of the second connecting rod 12.

[0025] The working principle of the utility model is:

[0026] When in use, the valve can be placed between two pipes first, and then one of the pipes is inserted into the output end 21, so that the pipe abuts against the sealing ring 22, and then the knob 24 is turned to drive the clamping plate 25 to move downward through the threaded rod 23 to clamp the pipe, and the output end 21 is assembled with the pipe. The input end 20 on the other side of the valve is assembled with the pipe in the same way.

[0027] Start the bidirectional motor 9 so that the bidirectional motor 9 can simultaneously drive the propeller 11, the crushing rod 13 and the crushing blade 14 to rotate through the output shaft, thereby crushing the impurities in the sewage and stirring the sewage at the same time, so that the sewage is constantly churning in the pipe, and the impurities in the sewage will also move with the sewage. When the valve is opened, the water flow can impact the movable ring 5, so that the movable wheel 7 outside the movable ring 5 can drive the movable ring 5 to move on the surface of the connecting rod 2, and at the same time, the elastic force of the telescopic spring 3 drives the movable wheel 7 to move back and forth.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0029] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
