Gravity type liquid quantitative water supply automatic closing apparatus

Abstract

The invention discloses a gravity-typed liquid quantitative water supply automatic closing device, comprising a frame, a water outlet tap, a positioning seat with a container positioning ring wall, a water closing valve with a side linked rod, a water taking container, a pressure spring, a container positioning platform with circumferential balance side walls and an independent connection hook which can hook the linked rod of the water closing valve. The working principle of the device is that liquid is injected into the water taking container on the positioning seat by the tap of the water inlet and the water outlet; when the accumulated gravity of the liquid flowed in the water taking container gradually presses the pressure spring to move downwards and synchronously drive the linked rod beside the water closing valve to move downwards, the water is injected continuously and the gravity presses down the pressure spring till the water inlet is closed when the quantitative water supply operation is completed as the quantitative liquid is injected into the water taking container. The gravity-typed liquid quantitative water supply automatic closing device can improve the collection work on the liquid with extremely low flowing speed, consumes no electric energy, and has no pollution, extremely low cost and high industrial utilization value.

Description

Technical field: [0001] The invention relates to an automatic closing device for liquid water supply, in particular to a gravity type automatic closing device for liquid quantitative water supply. Background technique: [0002] Most of the existing automatic shut-off devices for liquid water supply need to use components such as power supply, water level gauge and electromagnetic valve to complete the closing action when the water is full. The principle is that the liquid flows into the container through the designed flow channel through the electromagnetic valve in the flow channel. When the water level reaches the original design height, the water level gauge touches the liquid and floats up, cut off the power supply and close the electromagnetic valve in the water inlet flow channel, and the water inlet is closed synchronously. All water and electricity off actions. [0003] The mechanical water shut-off device that does not use electric energy mostly uses a float switch...

AI Technical Summary

Problems solved by technology

[0005] 1. Not suitable for filling smaller containers or containers with smaller openings

[0006] 2. It is not suitable for mobile containers, or continuous replacement container filling

[0007] 3. Use power supply, water level gauge, solenoid valve, easy loss, high maintenance cost, power consumption

[0008] 4. Part of the closing valve components must be installed in the container, soaked in the liquid for a long time, it is easy to contaminate the liquid, and the dirt is not easy to clean. If it is used in drinking water, it will easily lead to secondary pollution

[0009] 5. The stability of the float switch is poor, and it often leaks and cannot be closed, which does not save water
