Abstract

Disclosed is a device making use of the flow inertia to pump the water level of the fluid to elevate in the mechanical engineering; the fixing plate surface of an overflow valve and a tangent direction at the cavity bottom of the circular curved surface form an angle which is less than 90 DEG; the overflow valve is provided with a double-plate flat plate whose middle is provided with a hole; the lower part of the hole is provided with two screws of a door hinge for fixing the movable plate of the overflow valve; the both sides of the bottom of the movable plate of the overflow valve are punched into two conjoined columns which are inserted into the screw of a door hinged; a butterfly-shaped adjustable screw penetrating through the nut of the plate surface of the valve extends into the bottom cavity of a pump body. The inertia impulsive force of the water flow enables the movable overflow valve plate repeatedly move; water is pressed into an energy storage chamber and then is pressed into a water storage tube; the water at low level is elevated without man-power and electricity power.

Description

Low-head hydraulic pump

The utility model relates to the device that utilizes fluid inertia pumping fluid water level to rise in the mechanical engineering.

From lower force feed eminence, usually adopt electricity, fuel to finish as the power-driven pump body running of equipment fluid, the defective of this mode is that consumes energy, cost of equipment height, maintenance load are big; Easy shaft bottom water fetching device is to shake handle by manpower, and the compressed air-driven fluid level rises, and this method then very consumes manpower.

The purpose of this utility model is a strength of utilizing fluid potential difference inertia, promotes relief valve and returns reciprocating motion, and compressed fluid is washed one-way cock open, and water level is progressively risen, and forms bigger potential energy, lives for people and irritates general or the generating use.

Overall structure of the present utility model as shown in Figure 1, the front view of relief valve as shown in Figure 2, the top view of one-way cock is as shown in Figure 3.

Introduce the intake pipe 1 at water source and select seamless steel pipe or welded steel pipe for use, the surface of pipe scribbles resin layer, influence pump housing work and make intake pipe and pump housing good seal in order to prevent that foreign material from flowing into, between water inlet pipe mouth and pump housing cavity 5, be added with filter screen 2 and rubber washer 3, intake pipe 1, filter screen 2, rubber washer 3 usefulness flange screws 4 are connected and fixed with pump housing cavity 5.

The below of pump housing cavity 5 water inlets place, be one and become downwards at the bottom of the curved chamber of circle 6, make flowing water flow to relief valve 10 bigger inertia is arranged, 6 tangent direction forms less than an angle of 90 degrees at the bottom of relief valve fixed plate face 7 and the chamber, to accept the bigger impulse force of flowing water, above the pump housing cavity 5, a fixedly plane 8 of one-way cock is arranged, pump housing cavity 5 can adopt cast iron, cast steel or steel plate welding, and shape can be rectangular, rhombus, circle, ellipse, polygonal.The base 9 of pump housing cavity 5 adopts screw to be fixed on concrete base on the ground.

Relief valve 10 has a centre to have the double-layer plate of hole 11, upper panel 12 cylinder iron, cast steel makes, dull and stereotyped 13 usefulness rubber-like rubber of lower floor or plastics are made, the middle part that contacts with activity overflow valve plate 14 of double-layer plate is equipped with spring 15, and there are two fixedly door hinge screws 16 of activity overflow valve plate 14 hole 11 belows.Activity overflow valve plate 14 is flat boards bigger than hole 11, and its two bottom sides strikes out two disjunctor cylinders 17, inserts a door hinge screw 16, makes activity overflow valve plate 14 can seal and open hole.Attacked a nut 18 in the middle of the activity overflow valve plate 14, butterfly adjusting screw 19 is passed the length that nut 18 stretches to chamber 6 at the bottom of the pump housing, decision activity overflow valve plate 14 and double-

layer plate

12,13 formed angles and movable distance, butterfly adjusting screw 19 is in the top and the bottom of valve plate nut 18, respectively have one in order to fixing nut 20, relief valve 10 left and right side are fixed on the relief valve fixed plate face 7 of the pump housing with screw.

When flowing water pours by intake pipe 1 and fills pump housing cavity 5, usually the activity overflow valve plate of opening 14 is pushed to, with double-

layer plate

12,13 closures, seal hole 11, press activity overflow valve plate 14 artificially, when at this moment the water in the pump housing cavity 5 flows out, also got rid of the air in the pump housing cavity 5.Unclamp activity overflow valve plate 14, the impulse force of flowing water is closed and seal hole 11 with activity overflow valve plate 14 and double-

layer plate

12,13 again, a kind of reaction force makes activity overflow valve plate 14 downward again, has compressed the water in the pump housing cavity 5, washes one-way cock 21 open and enters accumulation chamber 30.

One-way cock 21 is installed on the pump housing cavity upper plane 8, and it is the valve body of a general structure.The valve core bar 22 that has screw up and down is with Returnning spring 23, Returnning spring 23 is added with packing ring 24 up and down, after valve core bar 22 puts in the disjunctor circular hole of plane 8 conical valves 26 from top to bottom, nut 25 is inserted in the bottom, valve core bar 22 on plane 8, be with down little big cone rubber packing ring 27, put circular balancing weight 28 again, adjust fixing with nut 29 at last.When the strength of water in the pump housing cavity 5 is very big, can washes cone rubber packing ring 27 open and enter accumulation chamber 30; When the strength deficiency of water, rely on the strength of Returnning spring 23 to close conical valve 26.

Accumulation chamber 30 also claims air chamber, it is the container of a sealing, the bottom connects pump housing cavity 5, outlet pipe 31 is equipped with in the side, the reciprocating motion that returns owing to activity overflow valve plate 14, hydraulic pressure in the pump housing cavity 5 is gone into accumulation chamber 30, the air of accumulation chamber 30 has been compressed in the increase of the water yield, has formed pressure, pushes the check valve 32 of outlet pipe 31 open, water is stored in standpipe 33, when the water of the cavity pump housing 5 constantly is pressed into accumulation chamber 30, and enter standpipe 33, because the effect of one-way valve 21 and check valve 32, the current of standpipe 33 will constantly rise, and people can introduce the eminence wet pit as required or directly use.

When current when intake pipe 1 enters pump housing cavity 52 meters drops is arranged, can produce 0.2Kg/cm ²Pressure difference, adjust butterfly adjusting screw 19 balancing weights 28, retaining screw 25,29, by the impulse force of flowing water, it is moving to make activity overflow valve plate 14 constantly return resurrection, do not need fuel and manpower, rely on savings, just can make water deliver to water level, form bigger potential energy up to 30 meters from lower, for farm, forest, orchard, garden pouring, be industry, living water, set up small hydropower station, also can be the draining of exploiting field, mine.
