Self-closing valve for water flow channel

This creation is about a valve body, especially a self-closing valve for a water flow channel.

According to the faucet assembly place and equipment are quite diverse. For some use states, the handle opening and closing modes are manually controlled, which may cause some problems, especially in public places, due to the water consumption of some users. Habits are not good, often there is a situation in which the faucet handle is not tightly closed after water use, resulting in waste of water resources. Therefore, it is necessary to design the faucet itself to prevent problems of user operation errors to ensure The faucet is maintained in normal operation.

At present, the common self-closing faucet structure is internally provided with a control valve. When used, the faucet water is opened by pressing, and the elastic force of the internal spring is used to allow the water to automatically block the water source to form a water shut-off state within a certain period of time, without After washing your hands, touch the faucet switch to save water and sanitation. However, in the conventional self-closing faucet structure, there is no see-through perforation to prevent vacuum inside the control valve. When the water flow pressure is greater than the spring pressure and the internal vacuum state is caused by poor diversion state, the control valve is delayedly closed. The time is not accurate, and it can't even be turned off automatically. It is a lack of conventional use, so it is necessary to improve it.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author has finally achieved a practical basis. creation.

The technical problem to be solved by the present invention is to provide a self-closing valve for a water flow channel in view of the above-mentioned shortcomings existing in the prior art.
