Flat low-pressure water valve assembly with small floating ball

Abstract

The invention discloses a flat low-pressure water valve assembly with a small floating ball. The flat low-pressure water valve assembly comprises a control module used for controlling the in and out of water, and an executing module used for introducing and discharging water, wherein a water inlet valve of the control module is communicated with a flat water valve of the executing module by a pipeline. A control mode of the water inlet valve of the control module adopts a normally-closed inner-blocking type, and is of derivative jogging control based on an electromagnetic valve of a washing machine, resulting that the small floating ball controls the on and off of the water inlet. A culvert used for controlling water flowing forwardly or backwardly is formed on a shell of the flat water valve, and opposite water flows can be formed respectively, so that the reversing of the water flows can be controlled.

Description

Technical field: [0001] The invention relates to a running water valve mechanism and a toilet flushing water tank component, in particular to a small floating ball flat low-pressure water valve assembly. Background technique: [0002] At present, the water inlet and outlet of the known flushing tanks have a floating ball, and the water valve of the water inlet part is mainly a floating ball with a diameter of ∮ 100mm, and the water valve is a normally open "outer plugging" type; the valve hole planes are opposite The rough gap is large, and a ∮100mm large floating ball mechanism is required to block the high-pressure water, because the large-diameter floating ball pin bearing is stressed, and the pin hole is easy to wear quickly, resulting in loose closing and reduced sensitivity. Therefore, the service life is short, causing water leakage. Again because of the valve cover of the water outlet, it is integrated with the float, but it can cause buoyancy and reduce the closing...

[0002] At present, the water inlet and outlet of the known flushing tanks have a floating ball, and the water valve of the water inlet part is mainly a floating ball with a diameter of ∮ 100mm, and the water valve is a normally open "outer plugging" type; the valve hole planes are opposite The rough gap is large, and a ∮100mm large floating ball mechanism is required to block the high-pressure water. Because the large-diameter floating ball pin bearing is stressed, the pin hole is easy to wear quickly, resulting in loose closing and reduced sensitivity.

Therefore, the service life is short, causing water leakage

And because the valve cover of the discharge port is integrated with the floating ball, it will cause buoyancy and reduce the closing force to cause leakage
