For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0021] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0022] A disassembly-free self-cleaning valve, as shown in Figure 1 and Figure 2 includes a valve body 1, a cleaner is arranged in the valve body, and a driving mechanism for driving the cleaner is arranged on the valve body; the cleaner includes a working rod 2, a working head 3 is mounted at the end of the working rod, and the working head is eccentrically arranged on the working rod; the working rod is axially the same as the valve body; because the working head is eccentrically arranged on the working rod, when the working rod rotates, the working head has a larger working coverage in the pipeline, which ensures the use effect of the working head and avoids the working head occupying too much space in the pipeline.

[0023] The driving mechanism includes a driving rod 4, one end of the driving rod extending into the valve body cooperates with the working rod, the driving rod is rotationally matched with the mounting hole on the valve body, and a driving rod seal is arranged in the mounting hole. The driving rod rotates to realize the axial movement of the working rod, so that the working head generates a feeding action; one end of the driving rod extends out of the valve body, and an operating handle 5 is arranged at the end extending out of the valve body. As an example, the working rod, the driving rod and the working head are made of 316L or titanium material, which has good corrosion resistance.

[0024] The working head includes a cylindrical section and a tapered tip at the front end of the cylindrical section, and a threaded structure is arranged on the outer wall of the cylindrical section; in a further improved scheme, the working head includes a cylindrical section, tapered tips are arranged at the front end and the tail end of the cylindrical section, and a threaded structure is arranged on the outer wall of the cylindrical section; such a structure design enables both ends of the working rod to clean the deposits, which is very suitable for working conditions with more deposits.

[0025] As an example, the transmission between one end of the driving rod extending into the valve body and the working rod adopts a worm gear transmission mode; the working head is arranged at a position where deposits are prone to accumulate; when it is necessary to clean the deposits, the operating handle is simply screwed to make the driving rod rotate the working rod, and then the working head rotates to clean the deposits accumulated near the working head. In this scheme, in order to improve the stability of the working rod, as shown in Figure 3As shown, a working rod guide can be arranged in the valve body, the guide comprises a support rod 6 arranged on the side wall of the valve body, and a guide ring 7 is arranged at the end of the support rod, and the guide ring is in sliding fit with the optical axis segment of the working rod. As an example, one end of the support rod is welded and fixed to the inner wall of the valve body, and the other end is welded and fixed to the guide ring. The guide rod adopts a round rod.

[0026] The self-cleaning valve has simple structure and is easy to operate. When the pipeline or the liquid level meter is blocked, the valve can always be kept in an open state. By rotating the operating handle, the driving rod is rotated to drive the working rod, and then the working head cleans the precipitates. Therefore, the self-cleaning valve can be widely applied to occasions of crystallization, solid entrainment or crystallization material pipelines and liquid level meters of storage tanks. The accumulated solid substances in the pipeline can be removed without disassembling the pipeline. The accumulated solid substances can be removed by rotating the driving handle, which is convenient, efficient, safe and reliable.

[0027] The above description is only the preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
