Description
Technical field
The present invention relates to a kind of water pump, particularly a kind of water pump of pressure differential of not power consumption.
Background technique
Pump working all can be consumed energy, the wretched insufficiency of the energy day by day highlights in the world today, because the serious scarcity of China's water resources, the water saving cry is surging, middle water reuse is also more and more admitted by people, but the recycling of middle water all relates to water pump, therefore the energy-conservation social effect that has more.People also do a lot of work on energy-conservation at present.Known middle water recycle device, multiple as (Chinese patent 01109949.6) structure, volume is big, and the cost height is unfavorable for promoting the use of.
Summary of the invention
In order to overcome the deficiency of aforementioned Waste water utilization device, the present invention discloses a kind of pressure-driven that supplies water and release of utilizing, and continuous type small volume, low cost, water pump simple in structure reach the purpose of energy-saving and water-saving.
The scheme that technical solution problem of the present invention adopts is: described pressure differential water pump, have only in the housing master chamber of four mouths of pipe one, with barrier film it is divided into two Room up and down, last chamber is the pressure of supply water chamber, following chamber is the pump hydroecium, and the fixing bar of center membrane passes the tube valve loose joint of chamber center hole and upper end, hole.Housing upper end two mouths of pipe are straight-through, and straight tube right part axis is provided with spout, and corresponding spout has the through hole that leads to the chamber on increaser and the tube wall to constitute Jet injector.Pressure water supply flows through spout from left to right for use.Housing lower end two mouths of pipe warp constitutes the water pump intake-outlet in the chamber down, and the water inlet direction is by two ducted one-way valves decisions.
The present invention inserts in the water supply line, in case people's water is arranged, spout produces negative pressure just continuous operation of water pump under the cooperation of central tube valve but pressure water supply is flowed through.
But the water pump that the invention has the beneficial effects as follows described pressure differential need not be specialized in energy continuous operation.Simple in structure, volume is little, cost is low, has reached the purpose of energy-saving and water-saving.
Describe concrete structure of the present invention and working procedure in detail below in conjunction with drawings and Examples.
Description of drawings

Fig. 2 is static schematic representation
Fig. 3 is a Venturi tube
Among the figure: the one-way valve of (1) water pump body (2) lower end cap (3) pressure of supply water chamber (4) pump hydroecium (5) barrier film (6) pull bar (7) spring (8) tube pump mouth of a river, valve (9) spout (10) increaser (11) through hole (12) water intake (13) water outlet (14) water sucking mouth (15) (16)
Embodiment
Described pressure differential water pump, be to form water pump body by water pump body that has intake-outlet and the lower end cap that has the water sucking mouth and the pump mouth of a river at one, with barrier film or piston main chamber is divided into pressure of supply water chamber and pump hydroecium in the housing master chamber, film or piston center fixation have the pull bar that passes center, chamber and turnover water pipe cinclides, the intrinsic flange plate in pull bar upper end, flange plate is set with outward and can makes axially movable tube valve with pull bar, the plane is fixed with spring on the pull bar flange, spring moves with pull bar, between tube valve and the hole wall the mobile gap of can supplying water is arranged, guarantee by 3 the projection of being no less than that evenly vertically distributes, projection can place hole wall or tube valve outer wall, the center hole effective section that its effective section passes greater than tube valve lower link.Right-hand member is provided with water orifice on the turnover water pipe axis, and corresponding spout place is provided with increaser is connected the chamber with aforementioned tube wall lower plane through hole formation Jet injector, and pressure water supply is flowed through spout from left to right for use.
Housing lower end cap two mouths of pipe warp chamber down constitutes the water pump intake-outlet, and one-way valve is arranged in the pipeline, and pump water aspect is by the direction decision of the forward one-way valve of two Guan Guanzhong.
In the described pressure differential water pump cut-in pressure water supply line, in case people's water is arranged, supply water and penetrate through spout at a high speed, last chamber via through holes produces negative pressure, but just continuous operation of water pump under the cooperation of central tube valve.
In the embodiment of the invention, pressure water supply takes place to flow when static, and water flows to the pressure chamber through center hole and through hole, force the descending drive pull bar of barrier film descending, barrier film is reached home and is contacted with the lower end cap upper surface, and pull bar drives tube valve closing center hole, keeps this state to take place to flow until pressure water supply.When water action generation consciously, open as water valve, pressure water supply will spray at a high speed through increaser through spout, and through hole produces negative pressure, makes the water sucking-off of chamber, this moment center hole closure can not continue upwards chamber water inlet, last chamber is the negative pressure attitude forces barrier film up, and negative pressure doffing valve closure is tighter, and following chamber volume increases, through water pump suction pipe, one-way valve is intake to water pump.Through the energy storage of pull bar pressure spring, a valve was up after spring force has overcome tube valve area and the long-pending value of negative pressure when barrier film went upward to top dead center.Because the tube valve area is definitely greater than the center hole section, entering the chamber negative pressure with the unlatching water of tube valve suddenly disappears, because a tube valve is a cylinder under shed, remain under buoyancy function in the pump that certain position is to keep the conducting of center hole in the water, this moment, pressure water supply entered chamber on the water pump.The present invention the time guarantees center hole definitely greater than the through hole section in design, so the water yield of Jet injector unit time sucking-off is less than the water yield that the center hole unit time enters the chamber, and the state that barrier film is descending when being returned to static state goes round and begins again.As long as have pressure water supply to flow through turnover water pipe in the pressure differential water pump of the present invention, pump will continuously be worked.In order to simplify technology, the turnover water pipe right-hand member can be reduced to the Venturi tube structure.Consider some specific (special) requirements of water supply, septation of the present invention also can adopt double-layer structure, or big or small structure of piston, or the composite structure of film and piston, so just, can overcome under the fortuitous event and to supply water and the pump water is interfered mutually, and can recently regulate pump bigcatkin willow journey and flow by the area that changes two barrier films or piston.Also can add constant pressure arrangement in water system will make the water pump cost lower and higher precision arranged.
Pressure differential water pump structure of the present invention is simple, cost is low, volume is little, reliable operation, energy-saving and water-saving have very high promotional value.
