Add water level recognition automatic valve closing device on the mechanical valve body

Abstract

The invention provides a method for adding a water-level-recognition automatic-valve-closing device on a mechanical valve, and belongs to the field of water feeding or oil feeding systems for household solar water heaters, factory water towers, oil-field oil storage tanks, various water storage tanks and the like. The method includes the step that the mechanical valve (1) is additionally provided with a main clamping support (2), a modified eccentric wheel (3), an original eccentric wheel (-3), a hoisting bucket (4), a water receiving tray (5), a reducing straight-through joint (6), a secondary water return pipe (7), a hoisting belt (8), a water outlet pipe (9), a packaging shell (10), an elastic hose (11-1), a positioning fork (11-5), a water level regulating support (11-4), a water return pipe (12) and other accessories, wherein the elastic hose (11-1), the positioning fork (11-5) and the water level regulating support (11-4) are located on a water tank (11). According to the principle, the positioning fork is used for determining the water level, overflowing return water which is higher than the positioning fork passes through the water return pipe, the reducing straight-through joint, the secondary water return pipe and the hoisting bucket and then generates acting force which is transmitted to an eccentric wheel, and then the mechanical valve is closed. The device has the effects that the valve can be automatically closed through water level recognition, the trouble that people wait to close water is saved, and semi-automation is achieved after the soul is added to the stiff mechanical valve.

Description

technical field [0001] The present invention relates to a mechanical valve widely used by people in daily life. The function of the valve body is to pass water, oil and various liquids, and it is manually opened or closed. Commonly used in household solar water heaters, factory water towers, oil field oil storage tanks and various water storage tanks and other water and oil systems. Background technique [0002] At present, there are two control methods for household solar water heaters, factory water towers, oil storage tanks, and various water storage tanks. One is to use a mechanical valve that is manually turned left or right to control the opening or closing. The advantage is that it is durable and stable, not affected by other external environments, and does not consume energy; the disadvantage is that it is easy to cause water leakage accidents due to opening the valve and forgetting to close it, and it increases the trouble of manual duty. 2. It is very good to use ...

AI Technical Summary

Problems solved by technology

[0003] In view of the deficiency that the existing mechanical valve cannot be automatically closed after opening, I have developed an automatic valve closing device after thinking about it. When the water level is low, the force generated by the overflowing return water can automatically close the valve and cut off the water, avoiding water leakage accidents due to manual opening and forgetting to close the valve, eliminating the trouble of manually waiting for the water to be closed, and not consuming energy, so that the rigid mechanical valve can be semi-automatic. , to achieve the desired effect
