Description
Technical field
The utility model belongs to the water works engineering technical field, when relating to tap water pipe network pressure and can not satisfy the requirement of building pressure of supply water, adopts the way of supplying water of secondary pressurization, and being specifically related to a kind of energy saving water supply does not have negative pressure line.
Background technology
Non-negative pressure method of water supply is to be the water source with the city planting ductwork, has made full use of the original pressure of city planting ductwork, forms airtight continuous relay supercharging way of supplying water, and good energy-conserving effect does not have the secondary pollution of water quality, is the development and the extension of pressurization or constant pressure water supply mode.
Present way of supplying water generally is divided into two types of direct supply or forced feeds, and the most frequently used still pressurization is supplied water.The mode that pressurization is supplied water is more, and common have three kinds of modes: a kind of is that tap water is held into pond or water tank, is conducted to attic tank through force (forcing) pump, is conducted to resident family by attic tank again; Another kind is through the frequency conversion Pressure Unit, and the water in the pond directly is conducted to resident family; Also having a kind of is that the non-negative pressure stabilized feeding engine of releasing is in recent years formed complete equipment; Be that the municipal tap water pipe network directly is connected with the complete unit that feeds water, and can not produce the novel way of supplying water of negative pressure to city planting ductwork, this way of supplying water biggest advantage is the own energy that has made full use of a water source; Reduced the pressurization pump lift; Reduced the power of force (forcing) pump, thereby made the operation and the cost of investment reduction by a relatively large margin of force (forcing) pump, energy-saving effect is obvious.
The utility model content
The purpose of the utility model is not have negative pressure line through a kind of energy saving water supply simple in structure, that cost of investment is lower.
In order to realize said purpose; The technical scheme that the utility model is taked is following: a kind of energy saving water supply does not have negative pressure line; Comprise running water pipe webmaster road, force (forcing) pump, high service pipe; It is characterized in that: on the running water pipe webmaster road of force (forcing) pump inlet, syphon is set, horizontal automatic air valve is installed at siphonal top.
The utility model is not changed the structure of the force (forcing) pump water side of prior art, and the structure of force (forcing) pump water side is that user's pipe network system is identical with prior art in other words.
The utility model syphon can be arranged in the piping shaft.Siphonal effect is to prevent the tap water pipe network is produced negative pressure, and when the hydraulic pressure at syphon top was negative pressure, air got into syphon through automatic air valve and destroys siphonage, and eliminating influences tap water pipe network negative pressure; The decision of siphonal height is to the influence degree of tap water pipe network, and is highly more little, influence big more, otherwise, influence more for a short time, can set according to the user situation of periphery.
The utility model utilizes the original pressure of pipe network one time, is after a kind of part with a pipe network water supply insufficient pressure is supplied through force (forcing) pump, satisfies the novel way of supplying water that building supplies water.This novel way of supplying water can substitute existing three kinds of way of supplying water; Need not build reservoir; Directly running water pipe is linked to each other with force (forcing) pump through syphon; Electrical control system is identical with the control principle of " reservoir+force (forcing) pump " way of supplying water, and switch board can adopt the frequency conversion mode, also can adopt the mode of non-frequency.
Different with existing two kinds of way of supplying water (a kind of is that reservoir+force (forcing) pump supplies water, and another kind is a non-negative pressure method of water supply current stabilization water supply facilities).The utility model is after a supply channel is not had the negative pressure design, the tap water pipe network directly to be inserted force (forcing) pump, has both utilized the energy that once supplies water, and has overcome the influence to a pipe network generation negative pressure again; Do not use the non-negative pressure method of water supply unit, but reach the effect of non-negative pressure stabilized feedwater unit, in addition a pipe network is not produced negative pressure and energy-conservation double technique effect, and the utility model is simpler than non-negative pressure stabilized feedwater unit, practice thrift cost of investment.
The way of supplying water that the utility model provides is avoided the secondary pollution of tap water effectively, and running cost is low, once invests for a short time, and the fabricating yard is little; Can utilize existing water facilities to transform, avoid overlapping investment, practice thrift cost; Electric automatic control is simple, and is identical with the control principle of existing way of supplying water; Realized full-automatic unmanned control on duty.
The utility model operating principle
:The tap water pipe network is in case supply water, and tap water directly gets into user's water supply network after syphon gets into force (forcing) pump, and the pressure sensor that user's pipe network system is equipped with is controlled the automatic start-stop of force (forcing) pump through the detected pressure signal of sensor.At the tap water pipe network promptly under normal situation of ductwork pressure, the opening, stop controlling of force (forcing) pump by the pressure signal of user's pipe network system; When the tap water pipe network supply water to occur unusually, pressure of supply water descends, and hydraulic pressure is during less than siphonal height H; Automatic vent is opened, and air gets into, and has destroyed siphonage; Decline along with liquid level in the syphon; The level sensing signal controlling force (forcing) pump of force (forcing) pump influent side quits work, thereby eliminated the tap water pipe network is produced action of negative pressure, has also protected the idle running of force (forcing) pump.After hydraulic pressure recovered normally, force (forcing) pump was opened automatically, and normal water supply has been realized the purpose that automatic control is supplied water fully.
