Problems solved by technology

During use, the outer surface of the transmission rod tends to accumulate dirt. When the dirt accumulates to a certain extent, the transmission rod cannot smoothly move in the perforation on the elbow-type diversion connection pipe, resulting in the float valve not working properly.

Abstract

The invention relates to an improved structure of a large flow ball float valve, which comprises a valve body, and a ball float mechanism driving a valve core of the valve body to act, wherein the valve body comprises a valve gate body with a valve gate, and a bent pipe type guide connecting pipe and the valve core which are connected with a water outlet of the valve gate body; the ball float mechanism comprises a bracket arranged on the bent pipe type guide connecting pipe, a ball float lever fixedly connected at the free end rotationally connected to the bracket, and a connecting rod; and one end of the connecting rod passes through a guide through hole on the bent pipe type guide connecting pipe and is connected with the valve core, and the other end of the connecting rod is connected with the lever. The improved structure is characterized in that the connecting rod positioned in the bent pipe type guide connecting pipe is provided with a descaling rotating wheel; and the descalingrotating wheel comprises a descaling rotating sleeve, and a helical blade which is arranged on the descaling rotating sleeve and drives the descaling rotating sleeve to rotate. Compared with the prior art, the improved structure has the advantages of automatically removing dirt accumulated on a transmission rod and ensuring movement smoothness of a transmission rod.

Description

Technical field: [0001] The invention relates to a float valve. Background technique: [0002] In the existing large-flow floating ball valve, the transmission rod that drives the spool to move must pass through the elbow-type diversion connecting pipe outside the valve, and the floating ball drive device installed on the elbow-type diversion connecting pipe bracket drive. Due to structural requirements, the perforation on the elbow-type flow guiding connecting pipe through which the transmission rod passes has a moving guiding effect, so the aperture of the perforation cannot be too large. During use, the outer surface of the transmission rod tends to accumulate dirt, and when the dirt accumulates to a certain extent, the transmission rod cannot smoothly move in the perforation on the elbow type diversion connecting pipe, causing the ball float valve to malfunction. Invention content: [0003] The object of the present invention is to provide an improved structure of a ...
