Special manual air inlet valve for device in bearing water storage equipment

Abstract

The invention relates to an air inlet valve, in particular to a special manual air inlet valve for a device in bearing water storage equipment, and solves the problem of incapability of automatic outlet water upon water supply cut-off of an external water supply system and formation of negative pressure at a high position of a pipeline system existing in the bearing water storage equipment. The special manual air inlet valve for the device in the bearing water storage equipment comprises an air collection pipe, an air collection pipe joint, an air inlet pipe, a seal ring, a push rod, a push button, a compression spring and a valve seat, wherein the lower end of the air collection pipe is provided with an opening; the air collection pipe joint is hermetically connected to the upper end of the air collection pipe; the upper end of the air inlet pipe extends into the inner cavity of the air collection pipe, and is close to the lower end face of the air collection pipe joint; and the lower end of the air inlet pipe extends out of the air collection pipe and is hermetically connected with a middle circular hole of the valve seat. Through the valve, the problem of incapability of automatic outlet water upon water supply cut-off of the external water supply system and formation of negative pressure at the high position of the pipeline system existing in the bearing water storage equipment is effectively solved; and the valve is suitable for various kinds of bearing water storage equipment.

Description

technical field [0001] The invention relates to an air intake valve, in particular to a special manual air intake valve installed in a pressurized water storage device. Background technique [0002] During the use of pressurized water storage equipment, when the external water supply system stops water and negative pressure is formed at the high level of the pipeline system, since the pressurized water storage equipment is filled with water, the sensitivity of the automatic valve of the pressurized water storage equipment will be affected by the The negative pressure at the water inlet decreases, causing the user to occasionally have no water when opening the water valve, which affects the normal use of the pressurized water storage equipment. In order to ensure the normal use of the pressurized water storage equipment, it is necessary to invent a special manual air intake valve installed in the pressurized water storage equipment in view of the phenomenon of no water coming...
