Abstract

The utility model discloses a closed bidirectional lift water pump which is provided with a first water inlet pipe, a secondary water inlet pipe, a first water outlet pipe and a secondary water outlet pipe. The openings of the water outlet pipes are closed. The water inlet pipes, the water outlet pipes, a cylinder plunger and a check valve form a bidirectional composite intake system. When the lever handle of the water pump is lifted upwards and is pressed downwards, the water can be obtained. Thus the water output of the water pump is big. The water pumped has a certain lift. The use is not influenced by terrain and the height of a water level. The utility model has the advantages of simple structure, convenient operation and low cost. The closed bidirectional lift water pump can be widely used for water drinking, water using and farm fields irrigating for rural districts and towns.

Description

Closed two-way lift water pump

The present invention relates to a kind of water intaking instrument, a kind of specifically closed two-way lift squeezer.The manual squeezer that generally use in existing rural area is unidirectional squeezer, this squeezer is uncovered structure or non-tight structure, and for once intake pipe and outlet pipe, thereby can only be when the piston of cylinder barrel rises come on hydraulic pressure, water only replaced in cylinder barrel when piston descended, by chamber down going to the chamber and can not extrude outside the cylinder barrel.The water yield of this squeezer is little, and the low and water that extrude of efficient does not have lift or lift very low, simultaneously summer when drawdown after, it is also very difficult to fetch water, and has not generally just inhaled water when drawdown when the distance piston is more than 8 meters.

The present invention proposes a kind of enclosed construction, the two-way lift squeezer that piston rises, descends and all fetch water.

Task of the present invention is achieved in that by intake pipe, secondary intake pipe, and compound turnover water pipe and cylinder barrel, piston, safety check that outlet pipe, a secondary outlet pipe are formed form a two-way water intake system.Intake pipe be connected on cylinder barrel below, the top and mouth of pipe that outlet pipe is connected on cylinder barrel is closed, the piston that piston rod passes outlet pipe and cylinder barrel connects together.The secondary intake pipe is identical with a turnover water pipe parallel connection respectively with the secondary outlet pipe, and by the flow direction of safety check control water, four safety check are contained in respectively in the pipeline of first and second intake pipe and first and second outlet pipe.When piston rose, the chamber formed vacuum under the cylinder barrel, and underground water is inhaled into the following chamber of cylinder barrel by intake pipe, meanwhile piston with the water of chamber on the cylinder barrel outside outlet pipe extruder; When piston descends, the water of chamber is forced out outside the machine through the secondary outlet pipe under the cylinder barrel and since this moment cylinder barrel on the chamber negative pressure appears, underground water then enters chamber on the cylinder barrel through the secondary intake pipe, when piston rises and descend, can both put on water come like this, extrude and go, realize two-way water intaking.Because suitable for reading a sealing of intake pipe of this squeezer do not have the pressure loss, or the pressure loss is very little, thereby the glassware for drinking water that extrudes during continuous setting-out has certain lift.Because an outlet pipe of this squeezer is connected on above the cylinder barrel, and an outlet pipe is on the stand-down when installing and using, and other parts such as cylinder barrel are embedded in underground, therefore as long as the length of the outlet pipe above the cylinder barrel that suitably extends, make the position of piston cylinder and the distance of level of ground water remain in certain scope, when groundwater recession, still water can be drunk up.

The great advantage of closed two-way lift squeezer is that water-outlet quantity is big, efficient is high, can not be subjected to the influence of landform and water level, and simple in structure, operates lightly, cheap, uses the water hygiene, can be widely used in rural area, town dweller's the drinking water, water, irrigation.

The specific embodiment of this invention is provided by following accompanying drawing.Accompanying drawing is the structural representation of the closed two-way lift squeezer of proposition according to the present invention.(1) is pipe joint among the figure, and (2) are an intake pipe, and (3) are the secondary outlet pipe, (4) be waste pipe, (5) are lever dolly, and (6) are lever handle, (7) be sealing gland, (8) are piston rod, and (9) are an outlet pipe, (10) be pipe collar, (11) are cylinder cap, and (12) are cylinder barrel, (13) be the opening tensioner ring, (14) be piston, (15) are the secondary intake pipe, (A), (B), (C), (D) be four safety check.An outlet pipe (9) adopts the steel pipe of φ 32mm, and the lower end is connected on the cylinder cap (11) by pipe collar (10), and the upper end is sealed with sealing gland (7); Secondary outlet pipe (3) and secondary intake pipe (15) are made with the steel pipe of φ 25mm, and an intake pipe (2) is connected with outside well casing by a pipe joint (1), and its size is matched according to actual needs; Cylinder barrel (12) is the gray castings of φ 127 * 4mm, or weld with seamless steel pipe, piston (14) is for being the steel casting of bowl type, on outer wall, be added with the opening tensioner ring (13) of twice steel or nylon, to guarantee that piston (14) and inner wall of cylinder can form good sealing, it is again little to move resistance; (A), (B), (C), (D) four safety check have adopted commercially available tongue plug formula structure, also can adopt spring structure or heavy hammer type structure.During work, on the bar handle (6) of arguing, piston rod (8) drives on the piston (14) and moves, cylinder barrel (12) is gone up the water of chamber through an outlet pipe (9), safety check (D), waste pipe (4) is forced out outside the pipe, and underground water then enters the following chamber of cylinder barrel (12) through an intake pipe (2), safety check (A).Lever handle (6) when pressing down piston rod (8) drive piston (14) and move down, the water of chamber is through safety check (B), secondary outlet pipe (3) under the cylinder barrel (12), waste pipe (4) is forced out outside the pipe, and underground water then enters the last chamber of cylinder barrel (12) through safety check (C), secondary intake pipe (15).Squeezer can both be got up underground water when lifting and pressing down last like this, and because outlet pipe is suitable for reading seal, and the glassware for drinking water that extrudes during continuous setting-out has certain lift, has realized two-way lift setting-out.
