Abstract
The liquid pumping device belongs to a liquid transmission apparatus and comprises a shell with cylindrical surface axial sliding fit pairs (5, 11) and a piston, wherein a moving part is the piston (5), the upper part of the piston and a liquid inlet (7) are respectively provided with a sheet-shaped one-way valve (4, 6) opened and closed by the sliding fit pairs (4, 3, 10, 7), and a support leg (9) is arranged at the inlet. The structure is easy to manufacture, convenient to use, easy to carry and suitable for various use conditions.
Description
The utility model belongs to the liquid transfer apparatus, and the extraction that is mainly used in liquid is shifted.
Known liquid suction mostly is gear pump type oil pump, and manually-operable is used for extracting from container fluid, is widely adopted.But because of it is relatively heavy, cost is higher, is not easy to carry and has limited using scope.Syphon tube also can be realized the transfer of liquid, and structure is very simple, is widely used in the occasion that needs.But the height of liquid has particular requirement before and after shifting, and set up the siphon condition must the emptying air, be full of and be transferred liquid, bring some inconvenience to use again.
The purpose of this utility model is the practical plan that proposes to transfer with simple and easy pressure transform institution liquid.
The utility model purpose is to realize like this, liquid suction comprises housing, with housing sealing moving element is movingly arranged, the liquid in-out mouth that links with housing, the valve component of set control channel break-make on the passage between the liquid in-out mouth, import transmission part with the power that above-mentioned moving element links, and the parts that are connected and fixed between each parts.Its middle shell is a cylndrical surface axial sliding fit pair with the moving element section of cooperation, moving element is the piston that cooperates with the shell inner surface slipper seal, be equipped with one-way valve with the liquid entering hole place on piston, also be provided with the connecting rod that passes housing on the piston, connecting rod is that slipper seal cooperates with housing.Like this, by liquid entering hole, the one-way valve on the piston, housing and liquid outlet thereof can form the passage that the liquid turnover is shifted, the motion of piston can change the pressure of turnover sap cavity in the housing, realizes the suction and the discharge of liquid, the flow direction of each one-way valve may command transfer liquid; Connecting rod can be imported and impel liquid to shift moving power, and its sealing with the housing connection place can guarantee by movement liquid only by the outlet discharge.Thereby can realize the handover of liquid by this structure, and piston sleeve structure is fairly simple, is easy to carry, the convenient use, and the purpose of this utility model is achieved.
The valve block of the utility model one-way valve and valve base chamber adopt the pair that is slidingly matched to link each other.This simple in structure, hoisting capacity is little, be easy to realize the control of liquid shift direction, make use all more convenient.
The utility model is provided with leg in inlet, with the extreme lower position of limiting inlet in being transferred liquid, can avoid this liquid suction to suck the deposition foreign material of liquid bottom.
The utility model has been realized the transfer of stand-by liquid with simple piston sleeve structure, equipment making and use all very easyly, and size can be set according to requiring, and it is standby to be easy to carry.
Accompanying drawing has provided the utility model embodiment's structural diagrams.
Fig. 1 is the liquid suction structural representation.
Dash number is described as follows among the figure:
1, handgrip 2, outlet 3, pull bar 4, valve block 5, piston 6, valve block 7, bottom 8, import 9, a pawl 10, pin 11, sleeve 12, top cover 13, seal ring
Now the utility model is described in further detail in conjunction with the embodiments.
The present embodiment size of main body can be made into φ 38 * 1040mm, as Vehicular portable formula oil-sucker, is equipped with car, and is easy to use.
This example comprises sleeve 11, the piston 5 that cooperates of slipper seal with it.The cover tube bottom is provided with the bottom 7 that sealing with it links, and covers and is shaped on axial hole, as liquid entering hole.Its central through bore and pin 10 are slidingly matched, and the pin upper end is associated with import valve block 6, and valve block 6 lower end surfaces and bottom 7 upper-end surfaces can form the pair that is sealed and matched.Sleeve l1 makes claw type 9 in the lower end.
Piston 5 tops are associated with the pull bar 3 of concentric, and remaining part is shaped on axial hole.Valve block 4 is slidingly matched with connecting rod, and its lower end surface and piston upper-end surface also can form the pair that is sealed and matched.The sleeve upper end is sealed and matched with top cover 12, and cover wall is shaped on through hole at sleeve 11 axis places and pull bar 3 is slidingly matched, and seal ring 13 is housed therebetween guarantees sealing.Top cover 12 1 sides are shaped on outlet 2, and flowmeter (not marking among the figure) is equipped with at this place.
During work, this oil-sucker placed wait the liquid of pumping, can be along axis reciprocating sliding pull bar 3.When pull bar drive piston 5 relative sleeves 11 moved downward, valve block 6 formed sealing with bottom 7, and valve block 4 is backed down, up to lower dead centre.When pull bar was up, valve block 4 formed sealing with piston 5, made the space of piston cavity of resorption I become big, and pressure descends, and fluid can be by import 8, and the through hole on bottom enters cavity of resorption I, drives piston 5 up to pull bar and goes upward to top dead center, and fluid just is full of cavity of resorption I.Descent of piston then, valve block 6 are multiple under pin 10 guiding to form sealing with bottom 7, with the cavity of resorption volume reduce, the pressure increase, fluid just backs down valve block 4, enters piston upper cavity II, until the piston lower dead center, makes the fluid of cavity of resorption I all enter epicoele II.When pull bar drives piston when up once more, valve block 4 complex edge pull bars 3 fall after rise, and form sealing with piston, and then the fluid among the epicoele II is just discharged by outlet 2 by up piston, and the outlet port flowmeter can show the output of fluid.Treat that meanwhile drawing liquid once more by the through hole of import 8, bottom 7, enters cavity of resorption I.Form by the handover process once more of oil pumping liquid.Seal ring 13 can prevent that fuel-displaced connection place from pull bar and top cover from overflowing.Prop up pawl 9 and can guarantee that the liquid suction import is away from treating drawing liquid bottom impurity, and fluid can't enter liquid suction when treating that drawing liquid faces nearly its bottom, thereby avoids bottom impurity to be extracted out by liquid suction, and this liquid suction can be made into φ 20～60mm, the series product of long 500～1000mm are used for various occasions.
