VALVE FOR POOL WATER TREATMENT INSTALLATIONS Russian patent published in 2022 - IPC C02F103/42 E04H4/16 

FIELD: water filtration.

SUBSTANCE: invention relates to the field of water filtration in swimming pools and baths and can be used to create valves that ensure the operation of purification plants, both in filtration modes and in filter washing modes. The valve for water purification installations contains a vertically oriented body in the form of a hollow cylinder, the upper end of which is made with the possibility of connection with the sewerage system, while in its upper part there is a branch pipe for connecting to the first inlet of the filter, a pipe for connecting to the outlet of the filtration pump, a connection pipe to the second inlet of the filter and a connection pipe to the pool, as well as a power cylinder installed on a single vertical axis with the body, the upper wall of which is connected to the outlet end of the body, and a controlled electromagnetic valve. A rod is installed along the single axis of the housing and the power cylinder, on which the upper and lower switching pistons are fixed in the housing, and the power piston is fixed in the power cylinder. A channel for controlling the position of the power piston is introduced into the device, made in the form of a tube, the inlet end of which is connected to the connection pipe to the filtration pump outlet, and the outlet end is connected to the inlet of a controlled electromagnetic valve, the first and second outlet tubes of which are connected, respectively, to the inlet of the power cylinder made in the wall under its upper wall, and with the input of the power cylinder, made in its lower wall.

EFFECT: simplifying the device and reducing power consumption.
