Abstract

The invention provides a zero gauge pressure opened diaphragm valve comprising a valve body, a bonnet, a seal base, a diaphragm and a miniature pump. The valve body is provided with an inlet cavity and an outlet cavity communicated with each other. The bonnet is disposed on the valve body. The seal base is disposed between the inlet cavity and the outlet cavity. The diaphragm is disposed between the valve body and the bonnet. A first control cavity is formed between the diaphragm and the bonnet. The diaphragm and the seal base are hermetically fitted. One end of the miniature pump is communicated with the first control cavity. Since the first control cavity is communicated with the miniature pump, under zero gauge pressure, the miniature pump freely controls the valve to fully open or close; water passing efficiency of the valve is improved.

Description

technical field [0001] The invention relates to the field of diaphragm valves, in particular, to a diaphragm valve that is opened at zero gauge pressure. Background technique [0002] At present, the diaphragm valve is connected to the compression member with an elastic diaphragm. The compression member is operated by the valve stem to move up and down. When the compression member rises, the diaphragm is lifted up to form a passage. When the compression member is lowered, the diaphragm is pressed on the valve. body, the valve is closed. This valve is suitable for breaking and throttling. [0003] Diaphragm valves are mainly used in the operation of low pressure water 1400kP. They are especially suitable for systems containing sand and other solid particles, especially in farmland irrigation. Under zero gauge pressure conditions, due to low water pressure, diaphragm valves are not fully opened, resulting in low efficiency. SUMMARY OF THE INVENTION [0004] The purpose of...
