Description

Control valve structure convenient to tank material is changed

Technical Field

The utility model relates to a soften and clean system, especially a control valve structure convenient to tank material is changed.

Background

1. Softening and purification systems in the market at present are generally in threaded connection with the opening part of the tank body and the whole control valve. When the filter material needs to be replaced, the connecting pipes such as the inlet and the outlet of the control valve, the drain outlet, the salt absorption port and the like are detached firstly, then the control valve is taken down from the tank opening in a rotating mode, the central pipe is pulled out of the tank, and finally the filter material is poured out and the inner cavity of the tank is cleaned. And after the above steps are finished, replacing the filter material, putting the fresh filter material and the central pipe into a clean tank, screwing the control valve, connecting all pipelines, and cleaning the water.

Because the center tube is in free state in the jar body, preassemble in advance can lead to the skew in the in-process of transportation, emerge. The general industrial tank body is large and has a lot of filter materials, and after the problems are generated during pre-assembly and transportation in advance, the filter materials can only be poured out on site and then reassembled. Therefore, conventional filter media replacement is performed in the field, which results in increased difficulty and complexity in servicing the product.

2. The tanks of industrial facilities are generally large and heavy. The control valve can not be accurately oriented after being screwed in, and can only be adjusted by rotating the tank body if the angle of the control valve after being screwed is not matched with the connecting pipe during installation. When the system is used and the control valve is replaced, this weight makes it more difficult to rotate the tank, since the interior of the tank will be filled with liquid in addition to the filter material.
