Leakproof device for water storing container

Abstract

The invention relates to a leakproof device for a water storing container, belonging to the technical field of the control of a fluid transportation pipeline. The device comprises a first port communicated with a water supply pipeline, a second port communicated with the water storing container, and a third port communicated with a water use end. The leakproof device is characterized in that the second port is formed by a water inlet cavity and a water outlet cavity, which are separated form each other; a first water flowing passageway arranged between the first port and the water inlet cavity of the second port is provided with a on-off controller, and the water outlet cavity is communicated with the third port by a second water flowing passageway; when the water use end is turned off, the on-off controller is under the status of switching off the first water flowing passageway; and when the water use end is turned on, the on-off controller is under the status of switching on the first water flowing passageway. Therefore, when the water use end is turned off and users does not need to use water, the first water flowing passageway is turned off, and even if the water storing container leaks, the water of a water source can not be compensated to the water storing container, so that the continuous leakage can be effectively avoided no matter whether the leakage is known by the user or not.

Description

Technical field [0001] The invention relates to an anti-leakage device, in particular to an anti-leakage device for a water storage container, which belongs to the technical field of fluid transport pipeline control. Background technique [0002] According to the applicant’s understanding, water storage containers such as storage-type electric water heaters will undergo oxygen and hydrogen evolution reactions due to the effect of galvanic batteries, resulting in corrosion. Even if the surface is painted, the anode rod is added, or the stainless steel material is used to delay corrosion, it is still inevitable that corrosion perforation will cause leakage. When the leakage occurs, if the user does not know, the leakage will continue because the existing water storage container is connected to the water source, causing a large area of ​​flooding and causing losses. [0003] In order to solve this problem, the Chinese utility model with application number 200820006351.3 discloses an ...

Problems solved by technology

[0004] The above-mentioned existing technologies all require the joint action of the detection and induction system, the signal processing system and the water inlet controller to cut off the water after leakage. If the control is not timely, if the reaction is too sensitive, it is prone to false alarms and malfunctions, and additional power supply is required, the structure is complicated, and it also brings troubles such as the need to prevent electric shocks and occupying too much space
