A multi-way valve for multi-stage compound bed series process

Abstract

The invention relates to a multi-channel valve used for a multistage double-bed series connection process. The multi-channel valve comprises a valve body. The valve body is internally provided with an overflow control cavity. The overflow control cavity is internally provided with a control valve rod. The left end of the valve body is provided with a sealing wall. The right end of the valve body is provided with a sealing wall. The left end of the control valve rod is located in the overflow control cavity. The right end of the control valve rod penetrates through the sealing wall. The valve rod comprises a valve rod body and a plurality of control sections. The control sections are in tight contact with the overflow control cavity. The valve body is provided with a first overflow channel, negative ion overflow valve ports, positive ion overflow valve ports and a second overflow channel. The first overflow channel and the second overflow channel each comprise a left overflow channel port and a right overflow channel port. The negative ion overflow valve ports and the positive ion overflow valve ports are alternately arranged. Each negative ion overflow valve port comprises a left negative ion overflow valve port body and a right negative ion overflow valve port body. Each positive ion overflow valve port comprises a left positive ion overflow valve port body and a right positive ion overflow valve port body. By adopting the multi-channel valve, the operation procedures are simplified, operation errors are reduced, cost is reduced, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to a valve body used for producing pure water and purifying organic products, in particular to a multi-way valve used for multi-stage compound bed series process. Background technique [0002] When multi-stage compound beds are used for series connection, the number of valves used to connect the compound beds will also increase greatly with the increase of series stages. Due to the large number of valves, the operation is cumbersome, slow, and error-prone when switching processes; There are also some valves that adopt fully automatic control, but the cost is obviously increased, and the use is uneconomical, which is not conducive to popularization. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a multi-way valve for the multi-stage compound bed series process in view of the deficiencies of the prior art. The disadvantage is to simplify the operation steps, reduce ope...
