Water distributing and collecting device

Abstract

The invention relates to a water distributing and collecting device which comprises a housing, a cylinder and a driving mechanism. The housing is provided with a hollow inner cavity; a first opening and at least two second openings formed at an interval are formed in the housing; the cylinder is positioned in the inner cavity of the housing and extends axially in the direction where the second openings are formed at the interval; the outer peripheral surface of the cylinder always keeps in contact with the wall surface, in which the second openings are formed, of the housing; a first through hole always keeping in communication with the first opening is formed in the end wall of the cylinder; at least two second through hole groups are formed in the axial direction at an interval on the outer peripheral wall of the cylinder; and the driving mechanism drives the cylinder to rotate in a stepping manner. The second through hole groups capable of controlling the open / close of the second openings of the housing and the open / close quantity of the second openings are arranged on the cylinder, and control valves for controlling the on-off state of waterflow do not need to be formed in thecorresponding second openings.

Description

technical field [0001] The invention belongs to the technical field of heating, and in particular relates to a water diversion device. Background technique [0002] In recent years, the use of geothermal heating in home decoration has gradually increased, and the application of sub-collectors matched with geothermal heating systems has become more and more extensive. The sub-collector is composed of a water-distributing main pipe and a water-collecting main pipe. The water-dividing main pipe is connected to the water supply pipe of the pipe network system. Its main function is to distribute the hot water from the pipe network system to the room through the floor heating pipe buried under the floor. Each room that needs to be heated. When hot water flows in the floor heating pipe, heat is transferred to the floor, and then radiated to the room through the floor. The other end of the floor heating pipe is connected to the water collecting main pipe of the sub-catchment, and ...

AI Technical Summary

Problems solved by technology

[0004] It can be seen from the above that the adjustment of the existing sub-catchment either uses a manual valve to control the opening and closing of a certain waterway, which is troublesome to operate; or uses an electric actuator that can be automatically controlled, but each branch waterway is installed, and the cost is relatively high.
