A water inlet is provided with a water inlet valve sheet. A piston provided with a water outlet valve sheet is arranged in a cylinder. The utility model is also connected with a pressure storage tank through a one-way valve. A user can manually and repeatedly press a handle, and the hand pump can suck water, can store water and can delivering water. The delivery lift of the water which is delivered is high, and the pulsation is little. The utility model has the advantages of labor saving and high efficiency.
Description
The utility model relates to water pump, especially a kind of hand pump.
Common agricultural irrigation water pump has a variety of, be divided into power water pump and hand water pump, power water pump generally relies on diesel oil, gasoline or electric power as the energy, drives the water pump irrigation and drainage of drawing water, can reach high-lift, big flow, the requirement that the water yield is stable, but its cost is higher relatively, it is serious to waste energy, irrigation and drainage cost height is not suitable for the user of rural households economy, suitable requirement, and what be not suitable for more that shortage such as mountainous rural area can source area promotes the use of.Hand water pump is little with its volume, and cost is low, and is economic and practical, be subjected to the user's of rural households welcome, but common hand water pump, unreasonable structure, with low content of technology, it is short to occur lift in the use, flow is little, and flow fluctuation is big, and the current trapping phenomena is serious, so just cause efficient not high, use effort.
The purpose of this utility model provides a kind of only by manually just reaching high-lift, big flow, the water pump that waterflow stabilization requires.
Technical solution of the present utility model is as follows: a kind of hand pump, include cylinder body 26, lever 6, cylinder body 26 inside are provided with piston 19, piston rod 7 connects lever 6 and piston 19 by link rod 2, cylinder body 26 bottoms are provided with water intake 14, seal arrangement is arranged at the top, it is characterized in that the water intake 14 and the joint of cylinder body 26 are provided with inlet valve seat 12 and water inlet valve block 11; Be close to piston 19 upper surfaces and be provided with piston ring 9, on piston 19 and piston ring 9, be installed with several inletes 24 around piston rod 7, water outlet valve block 8 pivot bush units are on the piston rod 7 and be pressed on the inlet 24, piston rod 7 is provided with bayonet lock 25, is stuck in water outlet valve block 8 upsides; Cylinder body 26 tops are connected with pressure-stored tank 16 by an one-way valve 15, and water outlet 17 is arranged at pressure-stored tank 16 downsides.The seal arrangement at cylinder body top comprises seal ring 4 and seal ring gland 3, and seal ring 4 can be rubber parts.Piston ring 9 and water outlet valve block 8 can be rubber parts.Water inlet valve block 11 and inlet valve seat 12 can all be rubber parts also.
Described cylinder body 26 tops are connected with lengthening cylinder 27, and piston rod 7 passes lengthening cylinder 27, and one-way valve 15 and pressure-stored tank 16 link to each other with lengthening cylinder 27 tops.
Hand pump provided by the utility model makes the up power continuously that do not need of current owing to adopt special water inlet structure and piston structure, only uses manually, just can promote current, thereby but energy saving, and can reduce cost, reduce the irrigation and drainage cost.Utilize pressure-stored tank can make the water outlet waterflow stabilization, and the lift height.
Further specify the utility model below in conjunction with drawings and Examples.
Fig. 1 is the utility model overall structure schematic representation.
Fig. 2 is the A-A generalized section.
Fig. 3 is the utility model top view.
Fig. 4 is the utility model lengthening cylinder structure schematic representation.
Embodiment one: as shown in Figure 1, hand pump provided by the utility model, comprise cylinder body 26, lever 6, cylinder body 26 inside are provided with piston 19, piston 19 can pump along cylinder body 26 inwalls, piston rod 17 connects lever 6 and piston 19 by link rod 2, joint at piston rod 17 and link rod 2 is provided with coupling head 1, cylinder body 26 outer wall tops and lever 6 are connected with pole 23, lever 6 promotes link rod 2 and drives piston rod 7 piston 19 is pumped along cylinder body 26 inwalls under the effect of pressure handle 18.Cylinder body 26 bottoms are provided with water intake 14, and the top of cylinder body 26 seals, and it adopts the seal ring 4 that is made of rubber parts to make cylinder body 26 end sealings, and piston rod 7 is passed wherein and air tight, and seal ring gland 3 is pressed in seal ring 4 in the sealing seat 5.
During use, whole hand pump is placed on well or the water cellar, connect good intake pipe, outlet pipe.When pressing pressure handle 18 downwards, drive lever 6, link rod 2 jigger lifting piston bars 7, piston 19 is moved upward, so just use water valve plate 8 downward sliding closing inletes 24, make the setting-out cylinder 10 of piston 19 bottoms be vacuum state, under the vacuum draw effect, water inlet valve block 11 is opened, and water enters in the setting-out cylinder 10 by water intake 14.When upwards lifting pressure handle 18, piston 19 moves downward, and water outlet valve block 18 upwards slides, and inlet 24 is opened, and hydraulic action makes into water valve block 11 close water intake 14 downwards, and the water in the setting-out cylinder flows to piston 19 tops by inlet 24.When depressing pressure handle 18 once more, piston 19 moves upward, water intake 14 is opened, water is full of setting-out cylinder 10 again, simultaneously, and the upwards lifting of piston 19, the water on cylinder body 26 tops is pushed in the pressure-stored tank 16 by one-way valve 15, the increasing of the water yield makes pressure-stored tank 16 tops air pressure moment increases, and reacts on water, makes water slowly flow out water outlet 17.The motion repeatedly of pressure handle 18 makes current constantly flow into pressure-stored tank 16, because the single effect of one-way valve 15, along with the increase of the water yield in the pressure-stored tank 16, its upper air pressure also significantly increases, the reaction force of air pressure, the level that water outlet 7 is flowed out is steady, and it is little to pulse, and higher lift is arranged.
Embodiment two: as shown in Figure 3, connect a lengthening cylinder 27 at cylinder body 26 tops, lengthening cylinder 27 is a hollow tube, communicate with cylinder body 26 inside, piston rod 7 lengthenings pass lengthening cylinder 27 and the coupling head 1 that is arranged at lengthening cylinder 27 tops, and coupling rod 2 and lever 6 are connected, like this, though lever 6 has very long distance from piston 19, still can piston 19 be pumped in cylinder body 26 inside by pressing pressure handle 18.One-way valve 15 and pressure-stored tank 16 link to each other with lengthening cylinder 27 tops.The employing of lengthening cylinder 27 is to have in the water kiln of certain distance or the pond on distance ground for convenience to draw water, and during use, can put into water kiln or pond to whole cylinder body 26, and the people can press pressure handle 18 on the ground and draw water, and water is flowed out continuously from water outlet 17.
