Abstract

The utility model relates to the liquid capacity changing type machinery, and is a mechanical manual water-lifting device for families and field watering, comprising a cylinder body, a piston part, a draw rod, a bottom plate, a water inlet and a water outlet connectors, a rocker rod and a stressing rod. The piston part of the cylinder body moves downwards, the ground water enters an upper cavity through the middle hole of the piston part. When the piston moves upwards, the movable valve (the middle of the movable valve is provided with a rubber cushion, the upper part of the movable valve is provided with a press plate, and the lower part of the movable valve is provided with a supporting plate and is fixed together by screws and screw nuts) of the piston part is downwards pressed on the middle hole by the pressure of the water self weight of an upper cavity. The sealing clearance between a rubber sealing bowl and the inner wall of the cylinder body is adjustable. The rubber cushion is provided between the cylinder body and the bottom plate. The utility model has labor-saving operation, small structural weight (16 kg) and large water output which reaches to more than 3 ton.

Description

Manual transfer pump

The utility model relates to fluid varactor machine, especially is a kind of good airproof performance, the big and a kind of hydraulic hand-pump in labour-saving of water-outlet quantity.

Existing armstrong's patent formula picotan need add diversion, effort, efficient is low, water-outlet quantity is few, mostly be people home-use (underground water is come up with being drawn into) seldom as the field usefulness of irrigating the fields during work; And the rubber Rubber washer of piston portion is because of damaging along pump easy fold of peripheral wall that (underground water is to be flowed toward epicoele by cavity of resorption along the space between rubber pad and the inboard wall of cylinder block in the work in the cylinder body bucket.Said upper and lower chamber means: the top of cylinder body inner carrier is epicoele, and the bottom is a cavity of resorption.) often change rubber pad, not only bothered but also waste material.

The purpose of this utility model is to overcome above-mentioned deficiency in the prior art and does not add diversion when a kind of work is provided, and water-outlet quantity is big, and the little manual picotan of labor intensity, and this picotan is for family's water lift usefulness, also can be for the farmland usefulness of irrigating the fields.

Task of the present utility model is finished by following approach.

Piston portion is in down stroke in the cylinder body, underground water enters inferior part of the cylinder block by the inlet valve doorway, and enters epicoele by the intermediate hole Movable valve place of piston portion, when piston portion during at up stroke, its Movable valve falls the intermediate hole that covers piston portion under the pressure of epicoele water; Guarantee good seal performance at three positions, promptly 1, the bottom of cylinder body, set up rubber gasket between cylinder body and the end (seat) plate, there is a rubber inlet valve upper end of water intake joint, and this inlet valve is locked on the end (seat) plate with a screw.There is a block pressur plate on the top of rubber inlet valve and with bolt and nut the two is fixed together, and to strengthen its skeleton, improves the sealing at place, inlet valve doorway during down stroke.2, the perisporium sealing of piston portion when inboard wall of cylinder block pumps, be to realize by the rubber seal bowl of this device piston portion setting, have under this seal bowl supporting plate, on have pressing plate, pressing plate top that setting sleeve is arranged, top board is arranged at setting sleeve top, all by wear the silk, nut check.3, the sealing of water inlet in the middle of the piston portion, be to realize by the movable inlet valve that is provided with, this movable inlet valve: on a limiting board arranged, have round supporting plate, a centre to accompany rubber gasket down, and with screw, nut check.This Movable valve moves about in the piston up-downgoing becomes, its radially rotary spacing be that (the loosening jaw of its opening fork plays leading role up and down on two setting sleeve surfaces for opening fork by the limiting board both sides.) realize.Because above-mentioned 1,2,3 sealing and past epicoele water inlet are to enter by piston portion intermediate hole passage, this picotan does not add diversion when working, water-outlet quantity is big, labor intensity is little.

Embodiment during the utility model is incited somebody to action in conjunction with the accompanying drawings is described further:

Fig. 1 is the down stroke structure diagram of " good airproof performance need not the manual picotan of diversion ",

Fig. 2 is the structural drawing of rubber seal bowl 6 in this device piston portion,

Fig. 3 is the structural drawing of the limiting board 15 of movable inlet valve in this device piston portion.

Zero, parts sequence number:

1 draws inlet valve rubber gasket 15 limiting boards in (pressure) bar 2 cylinder bodies 3 top boards 4 setting sleeves 5 press tables 6 rubber seal bowls 7 big palettes 8 pressing plate 9 rubber inlet valves, 10 bottom rubber gaskets 11 ends (seat) plates 12 water intake joints 13 little supporting plate 14 piston portions.

The utility model is a kind of mechanical type manual picotan, mainly by cylinder body (bucket) 2, piston portion, draw (pressure) bar 1, rocking bar, extension lever, the end (seat) plate 11, water intake joint 12, inlet valve 9, water outlet joint to constitute.Cylinder body is interior when the piston portion down stroke, underground water enters epicoele by the piston portion intermediate hole, a big palette 7 is arranged at the bottom of the rubber seal bowl 6 of piston portion, a press table 5 is arranged at top, two setting sleeves 4 are arranged and by wearing silk between press table 5 and the top board 3, nut is locked together all, the top of piston portion water intake is provided with a movable inlet valve, a little supporting plate 13 is arranged below the rubber gasket 14 of this movable inlet valve, there are both sides to have the limiting board 15 of opening fork above, and be locked together with screw and nut, the loosening jaw of the opening fork of limiting board is on the surface of two setting sleeves 4.Between cylinder body 2 and base plate 11, be provided with a sealing gasket 10, and be fixed together by three bolt and nuts that are uniformly distributed along the circumference.A pressing plate 8 is arranged at the top of rubber inlet valve 9, is fixed together by bolt, nut, is fixed at the end on (seat) plate 11 with this valve of key screw then.

Draw that can be between (pressure) bar 1 and the top board 3 lives in connecting also can be dead connection.

When rubber seal bowl 6 becomes to-and-fro motion (moving) in the piston portion up-downgoing, and seal between cylinder (bucket) body 2, after using a period of time wearing and tearing, the gap just increases, at this moment, can screw the nut of wearing on the silk, its metal setting sleeve 4 just compresses press table 5, and the circle of press table 5 (week) inclined-plane and bottom surface variograph are on rubber seal bowl 6, at this moment, the rubber seal bowl rises outward, can adjust its seal clearance.Cylinder body 2 is a foundry goods, and its inwall and lower end surface, bottom all need machining.

The physical dimension of rubber seal bowl 6: bowl end diameter is 144mm, and back cut diameter is 150mm, and the side height is 25mm, and bowl base thickness degree is 7mm, and middle water inlet aperture is 70mm.Between the madial wall of bowl and the inner bottom part is the obtuse angle, and certain inclination is promptly arranged.

In fact this picotan is exactly a kind of manpower single-acting water pump, close beta, and during work, if reciprocal 30-40 time of extension lever per minute, water-outlet quantity then hourly can reach more than 3 tons.Because of water-outlet quantity is big, so can be used as the use of watering of family's water lift and field.

The external diameter of cylinder body (bucket) 2 is 160mm, highly is 320mm, and the structure weight of this picotan is 16Kg, moves and manipulate all very convenient in the field.
