Diverter valve for roof water tank of building

Abstract

The invention provides a diverter valve for a roof water tank of a building. The diverter valve consists of a shell (1), a diverter shaft (2) and a pipeline (3), wherein the pipeline (3) penetrates through the shell (1); the diverter shaft (2) is arranged in the shell (1) and can move in a reciprocating manner; one end of the diverter shaft (2) is opposite to the side wall of the pipeline (3); a diverter channel (4) is formed in the diverter shaft (2); an inlet of the diverter channel (4) is formed in the side face of the diverter shaft (2); the diverter shaft (2) can completely cut off the pipeline (3) when penetrating through the pipeline (3), and the pipeline (3) is communicated with the diverter channel (4); an inlet of the pipeline (3) is further connected with a filtering pipe and a connection port with an inner diameter greater than the outer diameter of the filtering pipe; and the filtering pipe is provided with a pipe body with a blocked outer end. The diverter valve has the positive effects that when the pressure of the water tank is extremely high and a downstream pipeline leaks water, the diverter shaft penetrates through the pipeline to completely cut off the pipeline and make the pipeline communicated with the diverter channel; and furthermore, the inlet of the pipeline is further connected with the filtering pipe, thus realizing a filtering function of a diverter water path.

Description

technical field [0001] The invention discloses a diversion valve, in particular to a diversion valve for a water tank on the roof of a building, belonging to the field of plumbing equipment. Background technique [0002] The water tank on the roof of the building is often provided with a diversion valve. [0003] In the prior art, the diversion valve for the water tank on the roof of the building cannot automatically close and switch to the diversion state when the downstream pipeline leaks, and the diversion waterway does not have a filtering function, and the valve core is easily damaged. Contents of the invention [0004] In view of this, the present invention provides a diversion valve for a water tank on the roof of a building, which can automatically close the diversion valve when the downstream pipeline leaks, and make the diversion waterway have a filtering function, prolonging the use of the diversion valve life. [0005] Concrete scheme of the present invention...
