One end of the main body 1 is fixedly provided with a connecting flange 2; the connecting flange 2 is coaxially arranged with the main body 1; the connecting flange 2 is used for connecting with a pilot valve 11 to be dredged.
The other end of the main body 1 is fixedly provided with a closing part 3; the closing portion 3 is welded and fixed to the other end of the main body 1. The closing part 3 is provided with a threaded hole; the threaded hole is coaxially arranged with the main body 1; in the present embodiment, the threaded hole is preferably a fine thread to increase the sealing performance between the dredging rod 4 and the threaded hole. Further preferably, the length of the threaded hole is not less than 2cm, so that a long sealing area is formed, and the ejection of materials such as steam is avoided.
The dredging rod 4 is provided with an external thread; the dredging rod 4 is arranged on the threaded hole and matched with the threaded hole; the dredging rod 4 rotates and can move along the axial direction relative to the main body 1; the dredging rod 4 moves towards the pilot valve 11 to be dredged along the main body 1 until extending into the pilot valve 11 to be dredged. One end of the dredging rod 4 is fixedly provided with a dredging head 5; the dredging head 5 is provided with a plurality of edges and corners, which is beneficial to extending into a blockage for dredging. In the preferred embodiment, the dredging head 5 has a pyramid structure, so that the processing is convenient, and the dredging head can conveniently extend into a blockage in the rotation process. The dredging rod 4 moves axially while rotating, so that scaling can be cleaned quickly; moreover, the dredging rod 4 is connected with the threaded hole through threads, and an operator can obtain larger axial thrust only by slightly rotating the dredging rod, so that firm scaling can be cleaned.
The other end of the dredging bar 4 is fixedly provided with a turning part 6 for the operator to take the dredging bar 4 to turn. In the present embodiment, the outer wall of the rotating portion 6 is preferably prism-shaped so as to facilitate the rotation of the opening lever 4 by a wrench operation. The middle part of the rotating part 6 is provided with a through hole; an operator can select other rod pieces or tools with proper length to pass through the through hole according to the operation space to rotate the dredging rod 4, and the operation is convenient and fast. The control valve 7 is communicated with the inner cavity of the main body 1 for controlling the communication of the inner cavity of the main body 1 with the outside. The rotating part 6 can be in a ring shape, and can rotate by a wrench or be penetrated by an operating rod with a proper length for use in a narrow space, so that the application range is wider; the nut can also be welded on the dredging rod 4 directly.
