Problems solved by technology

However, the above-mentioned multi-way valves are all cock valves, and their disadvantages are that the cock surface is easily stuck by impurities in the fluid medium, causing the valve to fail to move or the sealing surface to wear and leak, and this kind of valve is not suitable for high work. pressure

Abstract

This invention is a hand-controlling multi-ported valve, its valve casing is a six grade column with the same axle center and the different diameter, in every grade of the valve casing is equipped with hollow disk-shaped back valve seats, disk-shaped front and back valve cores, radial and axle connected columnar front valve seat and valve cover, the valve rod is fixedly linked to the front and the back valve cores and treadly to the front and the back valve seats, the output interface is in the grade with front valve seat, the grade equipped with the front valve core has the interface matching with the inter-pipe of the bottom of the filter, the filtrating grade has the input interface, the grade equipped with the back valve core has the interface matching with the inter-pipe of the top of the filter, the back port of the valve casing is connected with the limber hole. The structure of this invention is reasonable, the operation is very convenient, the sealing capacity is good. It suits the high fluid pressure, and meanwhile it will not cause the block of the operation. Its fixing and maintaining are both convenient.

Description

technical field [0001] The invention relates to a control valve with multiple ports. Background technique [0002] For water treatment filters or some other filters, there is a production process of forward filtration and reverse flushing. The process piping and valve configuration are relatively complicated, the operation is cumbersome, and misoperation accidents are prone to occur. For this reason, many people have designed novel multi-way valves to replace the complex process pipelines and valve configurations of filters, such as "filter valves" and "multi-way control valves and their applications" disclosed in Chinese Patent Nos. 98225724.4 and 01205749.5 The "sand tank filter" composed of this valve effectively simplifies the process piping and valve configuration of the filter, greatly facilitating the operation. However, the above-mentioned multi-way valves are all cock valves, and their disadvantages are that the cock surface is easily stuc...
