Embodiment Construction
[0013] As shown in the accompanying drawing, the top of the water tank 3 is open, and one side of the water tank 3 is connected with a water inlet pipe 1. The water tank 3 is provided with a water control pipe 4. One end of the water outlet pipe 2 is a water outlet, and the other end is a water outlet. The water inlet and the water inlet end of the water outlet pipe 2 penetrate the water tank 3 from the bottom of the water tank 3 and communicate with the lower end of the water control pipe 4. A piston 5 is provided, and the outer surface of the piston 5 is liquid-tightly matched with the inner surface of the water control pipe 4. When the piston 5 is at the bottom of the water control pipe 4, the water inlet 6 can be blocked; the upper end of the water control pipe 4 is higher than the water tank 3, and the water tank 3 A sealing cover 13 is provided between the upper part and the water control pipe 4 to prevent water from running out. The sealing cover 13 is combined with the ...

The invention discloses a pipeline anti-running device, which comprises a water inlet pipe and a water outlet pipe. A sealed water tank is connected to the water inlet pipe. A water control pipe is arranged in the water tank. A piston is arranged in the water control pipe. The inner surface is liquid-tightly matched, the lower part of the water control pipe wall is provided with a water inlet hole, the upper end of the water control pipe is fixedly connected with an end cover, and the end cover is provided with a vent hole connecting the inner cavity of the water control pipe with the external air, and the water inlet of the water outlet pipe It is connected with the lower end of the water control pipe, and the outlet pipe is connected with a water outlet valve, and a water control valve is arranged above the water outlet pipe, and the water inlet of the water control valve is connected with the water tank, and the water outlet and the water outlet pipe of the water control valve are located between the water outlet valve and the water tank The pipe section is connected. The outlet valve and the water control valve are a pair of linkage valves controlled by the operating mechanism. When one of the valves is in the open state, the other valve is in the closed state. The device, when the water is stopped and the water outlet valve is forgotten to be closed, can prevent the water from running out after the water comes in again.
Description
technical field [0001] The invention relates to a pipeline anti-running water device. Background technique [0002] Households and office places use water generally through water taps. When using water, the water taps are turned on, and the water taps are turned off after use. At present, the commonly used faucet is to change the position of the valve core by the handle to realize the on-off of water. This kind of faucet has a simple structure and is convenient to use. When the faucet is turned off, it is easy to cause water to run out after the water comes in again, which is a waste of water resources and an unnecessary economic expenditure for users. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pipeline anti-running device for the above defects. [0004] In order to solve the above technical problems, the present invention provides a pipeline anti-running device with the following structure, which includ...
