Abstract

The invention relates to a mixing valve. The mixing valve comprises a valve body housing, wherein transverse two sides of the valve body housing are separately equipped with a left side connecting cover and a right side connecting cover; a water inlet connecting tube is arranged on the left side connecting tube; a ring-shaped water return tube is arranged on the outer wall of the water inlet connecting tube; one axial end of the water return tube is equipped with a sealed structure and the other end of the water return tube is provided with an opening structure; the end part of the water inletconnecting tube is further equipped with a water reflux tube; the outer wall of the water reflux tube is in sleeve connection to the inner part of the water return tube through the inner wall of thewater return tube; a tapered movable sleeve is arranged on a sealed position of the water reflux tube; one axial end of the movable sleeve is arranged on a tapered guide surface; the ring-shaped sidewall surface of the movable sleeve is in sliding connection with the sealed end of the water reflux tube; a water exhaust tube is further arranged on the right side connecting cover of the valve bodyhousing; a water discharge cover which is of a gradual reducing structure is connected on the water exhaust tube; a reducing end of the water discharge cover is connected with the water exhaust tube;the water exhaust tube is fixed with the movable sleeve; and a supporting spring is arranged between the water discharge cover and the water reflux tube.

Description

technical field [0001] The invention relates to a mixing valve, which belongs to the field of valves. Background technique [0002] The traditional flow limiting valve uses a floating piston block, which is connected by a spring, and uses water flow to impact the piston block to realize the floating of the piston block, so that the valve can be closed when the water flow is too fast. The size of the gap between the inner walls is limited, it is easy to be blocked, and when the valve is closed, there is a lack of buffer for the fluid, which can easily cause the pipeline to be impacted and affect the stability of the overall pipeline. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mixing valve to overcome the technical problem in the prior art that the flow limiting valve is easily impacted when closed. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005...
