Softening valve with mixed flow function

Abstract

The invention discloses a softening valve with a mixed flow function. Mixed flow station water holes are formed in the hermitically connected end surfaces of a group of a valve core and a valve seat; when treated softening water is required to be mixed and proportioned with raw water, a first end surface water hole rotating position on the lower end surface of the valve core is controlled to be communicated with the first station water hole in the end surface of the valve seat; a second end surface water hole rotating position on the lower end surface of the valve core is communicated with the second station water hole, the third station water hole and the first station water hole in the end surface of the valve seat respectively; the third and fourth end surface water hole rotating positions on the upper end surface of the valve core as well as the station water holes in the end surface of the valve seat are closed. Therefore, the softening water with higher flow entering the inner cavity of the second end surface water hole in the lower end surface of the valve core from the second station water hole in the end surface of the valve seat and raw water with lower flow entering the inner cavity through the first station water hole in the end surface of the valve seat are mixed and proportioned to be output. Small size and compact structure are realized. Compared with the prior art, the softening valve has the advantage of obviously reducing the processing cost of a product.

Description

technical field [0001] The invention relates to water treatment facilities; in particular, it relates to a softening valve with mixed flow function. Background technique [0002] The structure of the water treatment valve in the prior art is that a group of valve seats and valve cores are arranged in the core cavity of the valve body with sealing and butt joint end faces. Some softening, backwashing, forward washing, salt suction and slow washing station water holes are connected or closed in turn, and water treatment with different functions is performed sequentially. When the water treatment is softened, the hardness value of the treated water is certain. According to production needs, people usually need to adjust the mixing ratio of softened water and raw water to the water hardness value of the treated softened water before using it. At present, domestic and foreign water treatment valves are limited by the connection position and structure of each flow channel in the...

AI Technical Summary

Problems solved by technology

At present, domestic and foreign water treatment valves are limited by the connection position and structure of each flow channel in the valve body, and the station where the softened water and raw water are mixed and proportioned cannot be provided on the end face of the group of valve cores and valve seats.

Usually people can only control the mixing ratio of softened water and raw water through external pipelines and switches on the softened water outlet and raw water inlet of the valve body. Increased product processing costs
