Leakage-preventing water-stop valve

Abstract

The invention relates to a leakage-preventing water-stop valve comprising a water-stop valve core, a transmission device, a water absorbing body and a water-collecting tray, wherein the water-stop valve core is at least partially arranged in a main water inlet pipe; the transmission device is connected with the water-stop valve core in a transmission way; the water absorbing body is changed in volume or weight after meeting water; the water-collecting tray is used for collecting leaked liquid; the water absorbing body is arranged in the water-collecting tray and connected with the transmission device in the transmission way; and pressure generated due to the volume expansion or weight increase of the water absorbing body after water absorbing body absorbs the water drives the water-stop valve core to open or close the main water inlet pipe through the transmission device. According to the invention, the water-stop valve core is driven to actuate by adopting a physical method without energy consumption and can still keep the action under the condition of power off, thereby having more reliable leakage prevention.

Description

technical field [0001] The invention relates to a physical induction type anti-leakage valve. Background technique [0002] Currently commonly used water treatment equipment, such as pipeline machines or water dispensers, often have water leakage problems in daily use. Water leakage may cause problems such as machine failures and damage to residential decorations. These are all issues that manufacturers need to consider and Avoid problems. In the prior art, the leak-proof shut-off valves of water treatment equipment are usually electronic induction type, which has many disadvantages: [0003] 1. Power consumption. The existing electronic induction leak-proof water shut-off valve needs additional wiring for power supply, so it needs to consume power; [0004] 2. Leak-proof failure in the case of power failure. Since the electronic induction leak-proof water shut-off valve is powered by the power supply of the water treatment equipment, the leak-proof water shut-off valve ca...

AI Technical Summary

Problems solved by technology

[0003] 1. Power consumption. The existing electronic induction leak-proof water shut-off valve needs additional wiring for power supply, so it needs to consume power;

[0004] 2. Leak-proof failure in the case of power failure. Since the electronic induction leak-proof water shut-off valve is powered by the power supply of the water treatment equipment, the leak-proof water shut-off valve cannot operate normally in the event of a power failure, which will seriously affect product safety;

[0005] 3. The cost is high, and the electronic sensor leak-proof water shut-off valve requires many electronic accessories and the cost is high
