Abstract
The utility model relates to a pressure differential water storage tank automatic water supply device, which is composed of a normally open valve, a connecting rod, a gas-tight silo, a corrugated pipe (or a piston), a check valve, etc. The utility model is arranged in a water storage tank. Because the cross-sectional area of the corrugated pipe (or the piston) is greater than that of a valve plate of the normally open valve, when water level of the water storage tank reaches a certain height, water pressure forms pressure difference on the cross section of the corrugated pipe (or the piston) and the valve plate of the normally open valve to push the corrugated pipe to elongate (or the piston to move) top close the normally open valve, realizing automatic water-supply control. The device has the advantages of compact structure, flexible operation, tight opening and closing, strong integrity, small size, and convenient installation and replacement.
Description
The utility model relates to a kind of storage tank automatic water supply device, specifically a kind of pressure reduction that utilizes storage tank hydraulic pressure to cause, the mechanical device of control automatically of realizing supplying water.
Common storage tank automatic water-supply is by ball float control, and when water storage tank water level changed, ball float fluctuated thereupon, drives transmission mechanism and makes valve opening and closing, realizes the control of supplying water.Because the ball float volume is big, stroke is long, makes the transmission mechanism size bigger, is difficult to accurate motion, causes switching not tight easily, and damage easily.Because of volume is big, globality is poor, install, change all inconvenient in addition.
The purpose of this utility model provides and a kind ofly operates flexibly, opens and closes accurately, compact conformation, globality are strong, be convenient to the differential storage tank automatic water supply device installing and change.
The purpose of this utility model is achieved in that automatic water supply device is by sorrowful wall or the bottom be fixed in by the water inlet (5) that connects water inlet pipe in the storage tank, and by closeable normally open valve valve plate (4), link with the guide rod of normally open valve valve plate (4), the back-moving spring (1) that keeps normally open valve valve plate (4) often to open, housing (19), water inlet (5) on the housing (19), delivery port (15) and normally open valve valve opening (3), unidirectional opening, and by the telescopic seal bellows (10) of openend and storage tank UNICOM, the seal bellows (7) that connection connects normally open valve valve plate (4) and housing (19) reaches by normally open valve valve plate (4), seal bellows (7), housing (19), the gas-tight silo (9) that seal bellows (10) constitutes constitutes; Back-moving spring (1) is connected on the housing (19), is connected by connecting rod (6) between the closed end face of normally open valve valve plate (4) and seal bellows (10), and the section area of seal bellows (10) is at least greater than the maximum cross-section area of normally open valve valve plate (4).
Above-mentioned seal bellows (10) can be substituted by a piston (22) that can move back and forth at housing (19) inwall, be connected with normally open valve valve plate (4) by connecting rod (6), and constituting gas-tight silo (9) jointly by normally open valve valve plate (4), seal bellows (7), housing (19) and piston (22), the section area of piston (22) is at least greater than the maximum cross-section area of normally open valve valve plate (4).After tap water enters water tank through automatic water supply device, normally open valve valve plate and piston (or bellows) are produced pressure, the size of pressure depends on the product of water storage pressure and compression area.The section area of piston (or bellows) is greater than the section area of normally open valve valve plate, when water storage tank water level reach a certain height, piston (or bellows) can be stressed greater than the summation of normally open valve valve plate pressure and back-moving spring thrust, piston (or bellows) promotes connecting rod and axially moves, the normally open valve valve plate is closed, realize automatic water-supply control.Gas-tight silo has guaranteed the pressure reduction at normally open valve valve plate two ends and piston (or bellows) two ends.
