Description

Squeezer

The utility model relates to a kind of being used for and particularly mainly is suitable for the manual squeezer that household water or small farm are irrigated from the lower position squeezer of suction upwards.

Present widely used manual squeezer, its main structure is used to one-way valve, cylinder body, the piston of water into, the water storage tank that has water outlet etc. by the bottom and forms, when manpower is done to carry by the piston in the leverage drive cylinder body and is pressed down to-and-fro motion, under the control of one-way valve, constantly in inferior part of the cylinder block formation negative pressure and with water inspiration cylinder body, and the one-way sealing water that utilizes piston enters water storage tank above the piston by the gap between piston and the cylinder body, discharged by water outlet again.This its piston of manual squeezer is an integrated type elastic rubber plug, when moving downward, piston has sealing between it and the cylinder body, and form the gap and the sealing of not having between it and the cylinder body when moving upward, realize that with this water can enter the water storage tank above the piston, the shortcoming of this one-piece piston structure is: the surface friction drag between piston and the cylinder body is big and sealing is poor, because water is to enter water storage tank by the gap between piston and the cylinder body, so resistance of water drainage is big.The water inlet one-way valve of this squeezer bottom generally all is the form that adopts split type valve block and valve body and link to each other with hinge, and structure is complexity, and sealing effect is relatively poor.The structural deficiency of this in sum squeezer, thus caused its setting-out efficient low, use effort, wearing and tearing and life-span are short easily.

The purpose of this utility model provides a kind of improved squeezer, and it can improve setting-out efficient greatly, and the setting-out amount is big in the unit time, and uses laborsavingly, reduces wearing and tearing and increases the service life.

For achieving the above object, the utility model is taked following technological scheme:

The squeezer main structure is made up of cylinder body, cylinder body base, water inlet one-way valve, piston, the water storage tank etc. that has a water outlet.Wherein piston is to have a built-up piston that water one-way valve, this piston has the piston body that is shaped as the hollow belt cylinder, the space of its hollow space is built-in with the one-way valve spool, on piston body, be with ring-type tazza shape seal ring, the one-way valve valve body of shape is embedded in the piston body ringwise, have corresponding sealed faying face with the one-way valve spool, the while valve body has a prominent edge and tightly suppresses seal ring.The one-way valve of wherein intaking is the integrated type valve that valve block links to each other with valve body, this valve is for to excavate a circular valve block with the corresponding elastic caoutchouc of cylinder body base geomery center, making it to keep continuous partly reaching does not separate with parent to play a hinge effect, and on valve block, being fixed with the metal weights thing, the diameter of this valve block is greater than the diameter of water intake on the cylinder body base.

As further improvement of the utility model, the above-mentioned piston body that is shaped as the hollow belt cylinder is a uniform board rib on hollow circular cylinder, the plate rib crosses to form in the center and limits the cage that the one-way valve spool in it moves, and intersection forms a boss, middle tapping.

As further improvement of the utility model, the taper pawl that the one-way valve spool in the above-mentioned piston body equates for uniform width on the disk with accurately machined external conical shape face, thickness, Dui Ying one-way valve valve body also has accurately machined inner conical face accordingly with it.

After adopting the technological scheme of above-mentioned squeezer, the piston of this squeezer is parent with the dish type foundry goods and is with ring-type tazza shape seal ring thereon, strengthened the seal thickness between piston and the cylinder body, increased sealing, compared simultaneously and reduced surface friction drag with existing integral rubber piston; Have an one-way valve in the centre of piston, when piston moves downward, the one-way valve spool moves upward and opens, underpiston water can enter water storage tank swimmingly thus, reduced resistance of water drainage greatly, when piston moves upward, this one-way valve spool is moved downward to the one-way valve valve body under the effect of deadweight and hydraulic pressure, spool matches with the fine finishing conical surface of valve body and has reached good sealing, the metal cage that plate rib on the piston body crosses in the center and forms, limit the one-way valve spool mobile space in it, can reset well to guarantee it.Its valve block of water inlet one-way valve and valve body in cylinder base are an integral body, and be simple in structure, simple for production, simultaneously good sealing effect arranged also, and this weight of metal that is fixed on the valve block can guarantee that valve block is closed smoothly, makes it have better sealing.Squeezer of the present utility model is in sum compared with existing squeezer, its piston seal is good, frictional resistance is little, also reduced resistance of water drainage with advancing its structure, water inlet one-way valve in bottom also has better sealing, so can improve setting-out efficient greatly when using, the setting-out amount is big in the unit time, and also laborsaving, reduce wearing and tearing and increase the service life.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is a kind of example structure sectional view of the present utility model.

Squeezer structure of the present utility model as shown in Figure 1, it mainly is made up of cylinder body 4, cylinder body base 20, water inlet one-way valve, piston, the water storage tank 12 etc. that has a water outlet 14.Wherein piston is to have a built-up piston that water one-way valve, this piston has the piston body 8 that is shaped as the hollow belt cylinder, it is a uniform board rib 9 on annular disc, plate rib 9 crosses in the center and forms the metal cage, to limit the mobile space of the one-way valve spool 15 in it, guarantees that it can reset well and makes the one-way valve closing seam, intersection forms a boss 10, in tapping, cooperate with connecting rod 11 to link to each other, connecting rod 11 links to each other with hinge with rocking handle 13 again.Be with seal ring 7 on piston body 8, it is a ring-type tazza shape elastic caoutchouc circle, and its tazza shape is in order to have strengthened the seal thickness between piston and the cylinder body, to have guaranteed sealing.The one-way valve valve body 18 of shape is embedded in the piston body 8 ringwise, and it has one and prominent tightly suppresses seal ring 7 along 5, is connected one with adopting bolton between the piston body 8.The one-way valve spool of in the metal cage of piston body 8, being put 15, it and one-way valve valve body 18 have corresponding sealed faying face, this junction plane adopts the fine finishing external conical shape face 16 of spool 15 to match with the accurately machined inner conical face 6 of valve body 18 in the present embodiment, the while spool 15 taper pawl 17 that uniform width, thickness equate on its disk, this structure can guarantee that spool 15 successfully slips in the valve body 18, have leading role, make one-way valve closing seam well.The water inlet one-way valve is the integrated type valve that valve block 2 links to each other with valve body 19, it is specially and is excavating a circular valve block 2 with the corresponding elastic caoutchouc of cylinder body base 20 geomeries center, making it to keep continuous partly reaching does not separate with parent to play a hinge effect, and on valve block 2, be fixed with metal weights thing 3, can guarantee that valve block 2 is closed smoothly, make it have better sealing, the diameter of this valve block 2 is greater than the diameter of water intake 1 on the cylinder body base 20, this integral check valve is installed on the bottom of cylinder body 4, is compressed and is fixed by base 20.
