Description
Technical Field
The utility model belongs to the technical field of the valve body, more specifically says, it relates to a zero water pressure water intaking valve.
Background
The existing water inlet valve for controlling water flow of equipment such as washing machines, water heaters and the like is usually set to have a working water pressure range of 0.02-1.0 MPa. When the electromagnetic valve is opened, the sealing diaphragm is jacked up by means of the water pressure difference between the valve inner cavity and the water inlet to form a water passing state. In order to ensure the sealing performance under low water pressure, the rubber diaphragm is designed to form a certain pressure to act on the end surface of the water outlet. When the water pressure of the water inlet is lower than 0.02MPa, the thrust formed by the water pressure difference is not enough to overcome the pressure of the rubber diaphragm acting on the end face of the water outlet. At this time, only a dripping phenomenon occurs, and a normal continuous water flow cannot be formed. At present, a large number of household electrical appliances such as washing machines, solar water heaters and the like enter foreign markets, similar to countries such as India with water resource shortage, and due to low water pressure, the existing water inlet valve cannot meet the use requirements easily. The market has urgent demand for a water inlet valve with large flow under the water pressure of 0-0.02 MPa, and the existing electromagnetic water inlet valve can be completely opened only when the pressure difference is large enough. And only when the water inlet pressure is large enough, the enough pressure difference can be generated. Therefore, the common water inlet valve cannot work normally under the non-pressure condition.
