Description
Technical field
The utility model belongs to supply equipment technical field more particularly to non-negative pressure method of water supply field, and in particular to Yi Zhongwu
Tower supply equipment.
Background technique
Non-negative pressure water-supply device usually described in us, generally referred to as non-negative pressure frequency-changing water supply device, also cry frequency conversion without
Negative pressure water-supply installation, the supercharging equipment being directly on water supply network.Traditional way of supplying water be unable to do without reservoir, water storage
The general running water pipe supply of water in pond, becomes zero after having the water of pressure to enter pond in this way, causes a large amount of energy unrestrained in vain
Take.And non-negative pressure water-supply device is a kind of ideal energy-saving water supply equipment, it be it is a kind of can directly be connect with tap water pipe network, it is right
Tap water pipe network will not generate the secondary water supply equipment of any side effect, directly laminate confession on the basis of municipal ductwork pressure
Water, it is energy saving, and also have that totally-enclosed, pollution-free, land occupation amount is small, quick for installation, reliable for operation, easy to maintain etc. many
Advantage.
Diaphragm type pressurized tank is usually used in non-negative pressure water-supply device, but current diaphragm type pressurized tank is in the production process
It needs to use welding procedure, exists in production complexity and use and the problems such as membrane ruptures, gas leakage occur, the reason is that in pressurized tank
Manufacturing process in, need the case weld for docking two at a complete tank body, thus need first to be added in diaphragm
It is welded again in shell, and in order to guarantee that cell parts have enough spaces, diaphragm is generally arranged in pressurized tank
Between position, it is close with the weld of shell, but the heat generated in the welding process certainly will cause to damage to diaphragm, and then reduce
The service life of diaphragm and pressurized tank, the case where being frequently run onto membrane ruptures in use.
Utility model content
The utility model provides a kind of tower-free water supplying, is using for solving non-negative pressure water-supply device in the prior art
The technical issues of the case where being frequently run onto pressurized tank membrane ruptures in the process.
The technology employed by the present utility model is
A kind of tower-free water supplying, for solve existing non-negative pressure water-supply device be frequently run onto use pressurized tank every
The problem of film ruptures, including pressurized tank, the steady-flow tank connected by diversion pipe, is connected on diversion pipe into water water pump, the pressure
Power tank includes that hemispheric upper tank body a and lower tank a, the upper tank body a and lower tank a are mutually interlockingly connected and constitute the spherical pressure of sealing
Power tank, pressurized tank is interior to be equipped with diaphragm, and diaphragm is clamped at the snapping of upper tank body a and lower tank a and is divided into pressurized tank up and down
Two seal cavities, the upper tank body a be equipped with intake valve, the bottom lower tank a be equipped with pressure control water feed apparatus, check-valves,
Outlet valve.
The course of work of this supply equipment are as follows: the water in steady-flow tank is pressed and delivered in pressurized tank by water inlet water pump, current stabilization
Tank, which plays, prevents the case where negative pressure is flow backwards, and then water enters pressurized tank by diversion pipe and water inlet water pump, wherein pressure
The working principle of tank are as follows: first according to the atmospheric pressure state of upper tank body a choose whether to be added from intake valve into upper tank body a air or
Air is discharged, reaches suitable initial gas pressure to adjust the air pressure in upper tank body a, then starting water inlet water pump, water is passed through only
