A salt circuit control device for a softening valve

Abstract

The invention discloses a salt path control device of a softening valve. The salt path control device comprises a shell, a piston rod assembly, a locking sleeve and an end plug. A cavity is formed in the shell. A fluid inlet path is formed on the side wall of the shell. A sealing step is further arranged on the side wall under the fluid inlet path. The end plug is fixed at the bottom of the shell. A second through hole is formed on the end plug. The piston rod assembly comprises a piston rod, a clamping ring, a positioning seal ring and a positioning table. The piston rod penetrates a first through hole. The positioning table is fixed at the bottom end of the piston rod. The positioning seal ring is sleeved outside the positioning table. The clamping ring is fixed on the piston rod. A spring for resetting the piston rod assembly is arranged on the piston rod between the clamping ring and the shell. The piston rod assembly penetrates the locking sleeve and is locked through the same. Structures of the piston rod assembly and the shell are changed, members are reduced, cost is saved, assembling is simple, and time consumption is short.

Description

technical field [0001] The invention relates to a control device, in particular to a salt path control device for a softening valve. Background technique [0002] The salt circuit control device of the softening valve is mainly responsible for the opening and closing of the salt circuit of the softening valve. When it is opened, the liquid can enter and exit. When it is closed, the internal liquid will not leak and the external liquid will not enter. [0003] The traditional salt circuit control device of the softening valve includes a housing, a piston assembly and an end plug. The housing is provided with a cavity that penetrates up and down, and the side wall of the housing is provided with a liquid inlet channel. The port of the port is fixed with an open flow bracket, and the side wall below the liquid inlet channel is also fixed with a flow-limiting orifice bracket. The flow-limiting orifice bracket is fixed with a flow-limiting buckle. The piston assembly includes a t...
