Embodiment 1
[0089] Embodiment one, figure 1 ~ Figure 3, Figure 5, Figure 7 ~ Figure 17. This multi-way control valve for softening water treatment equipment mainly includes a valve body connected with raw water inlet, clean water outlet and sewage outlet, and a valve core connected to the valve stem is placed in the valve body; it is composed of two valves The spool connected by the rod 4 is placed in the left and right spool cavities of the valve body 10; Combination sealing structure; the end faces of the two movable valve plates 5, 30 and the end faces of the valve stem 4 are respectively fitted with grooves and protrusions (as shown in Fig. 2-Fig. 6); in order to increase the water flow and In the flow space, a volume groove 12 is provided on the mating end faces of the two valve stems 4; a fan-shaped channel extending radially from the central hole to its edge is provided on the end faces of the moving valve plates 5 and 30. Hole 13 (shown in Figure 3 and Figure 5). On the end fac...
Embodiment 2
[0090] Embodiment two, figure 1 - Figure 2, Figure 4, Figure 5, Figure 9-Figure 17, Figure 21-Figure 22 shown. The structure of the present invention is the same as that of the first embodiment and will not be described in detail. Its difference is: at the salt inlet 31 and 32 place of described valve body, be connected with ejector 27. On the end face where the left movable valve plate 5 and the fixed valve plate 6 are joined, a guide blind hole 26 (shown in FIG. 4 ); On the end face between the holes 16, fan-shaped salt holes 28 ( Figure 21 Shown); On the end face between the fan-shaped water inlet hole 14 and the drain hole 16, the fixed valve plate 29 on the right is provided with a salt hole 23 ( Figure 22 shown). It not only constitutes a fixed bed countercurrent regeneration softening valve for softening water treatment equipment.
Embodiment 3
[0091] Embodiment three, figure 1 -Figure 2, Figure 4, Figure 5, Figure 9-Figure 16, Figure 18- Figure 22 shown. The structure of the present invention is the same as that of the second embodiment and will not be described in detail. The difference is that the upper and lower water distribution holes 15 and 17 on the left and right fixed valve plates pass through the upper water distribution hole 19 and the lower distribution water hole 20 of the left and right valve core chambers of the valve body respectively, and connect with the valve body. The lower water distributor connection hole 21 that is connected with the water distribution connector 25 is connected with the upper water distributor connection hole 36 (Fig. 18- Figure 20 shown). That is, it constitutes a floating bed softening valve for water treatment equipment.
