Abstract
The utility model relates to a filtering type hand-siphon liquid-feeding pump, which belongs to the technical field of machine tools. An upper cover, a lower cover, a pump casing, a liquid inlet pipe, a liquid outlet pipe, a piston assembly, a handle, a connecting rod, pins, a one-way valve, O-shaped rings, a light float valve plate, a spacing net and fixed screws are formed into a liquid-feeding pump. An outlet pipe is provided with a filter. The light float valve plate is arranged in the valve chamber of the lower cover and then covered by the spacing net and fixed by the screws to form a float one-way valve. Liquid in the pump can flow out automatically when siphonage condition is satisfied.
Description
The utility model is a kind of manual liquid feeding instrument, belongs to the machine tool technical field.
Fluid filling pump is a kind of common tool, and the manual fluid filling pump life-span of using in producing at present is short, the operation effort; The motor-drive pump complex structure, and can not in the production that the fire prevention conditional request is arranged, use.
The purpose of this utility model just provide a kind of simple and reliable for structure, easy to maintenance, use the laborsaving life-span long and filter is set at liquid outlet, the novel fluid filling pump of filtration is arranged.
Filtering type of the present utility model is manual---and the siphon fluid filling pump mainly comprises lightweight float valve block (1), spacing net (2), set screw (3), piston assembly (4), O type ring (5), drain pipe (6), filter (7), pump case (8), loam cake (9), pin (10), handle (11), connecting rod (12), one-way valve (13), lower cover (14) and liquid inlet pipe (15) composition.
To pressing down handle (11), piston assembly (4) moves from bottom to top during use, and one-way valve (13) is closed.Piston assembly (4) top air is discharged from outside the pump by compression; Piston assembly (4) below volume becomes the big negative pressure that forms.Under the atmospheric pressure effect, material is from liquid inlet pipe (15) mouthful inflow; Backing down the unsteady valve block (1) of lightweight enters in the pump case (8).At this moment lightweight valve block (1) the spacing net (2) that screw (3) fix that is fixed that floats blocks, can only be unsteady in the unidirectional valve pocket that spacing net (2) and lower cover (14) are formed, and the unsteady one-way valve of composition.
When upwards lifting handle (11), piston assembly (4) is operation downwards, and one-way valve (13) is opened, and the lightweight valve block (1) that floats is pushed down lower cover (14) valve port downwards.Material enters piston assembly (4) top.Up and down reciprocatingly pull handle (11), under the atmospheric pressure effect, material just can constantly be pressed in the pump case (8), flows in the container of accepting material through drain pipe (6) again.When discharging just often, handle (11) is pressed downwardly onto minimum point, at this moment piston assembly (4) is positioned at upper dead center.Form a connecting vessels by being inserted into liquid inlet pipe (15) pump case (8) and the drain pipe (6) that container adorned in the liquid material like this.At this moment as long as liquid outlet is lower than the liquid level of being taken out material in the container, the less material of viscosity just can be continuously outflowed by siphonage.Play manually---the effect of siphon liquid feeding.
Adopting the utility model filtering type manual---its advantage of siphon fluid filling pump is that the back several times material of manually-operable just can flow to another container from a container; Being used for the big material of viscosity can be manual, and can filter material.This tools structure is reasonable in addition, and few easy workout part uses laborsaving, easy to maintenance.
Figure of description is a structural representation of the present utility model.Wherein by lower cover (14), the lightweight unsteady one-way valve that the spacing net of valve block (1) (2) and set screw (3) form that floats.
Embodiment of the present utility model is as follows: the unsteady valve block (1) of lightweight is put into lower cover (14) valve port chamber, cover spacing net (2) and with set screw (3) spacing net (2) is fixed on the lower cover (14), form the one-way valve that floats.Respectively loam cake (9) and lower cover (14) are installed in pump case (8) upper and lower end; Piston assembly (4) is installed in the pump case (8); O type ring (5) and one-way valve (13) are contained in the groove of piston assembly (4) respectively and on the check-valve port; Load onto liquid inlet pipe (15) at lower cover (14), connecing connective pole (12) on drain pipe (6), the journal stirrup in the outlet of pump case (8); Filter (7) is housed on the drain pipe (6); Adorn handle (11) on the piston rod head of piston assembly (4), pin (9) is loaded onto in piston assembly (4) and handle (11), handle (11) and connecting rod (12), connecting rod (12) and pump case (8) journal stirrup hinged place.Just it is manual to form filtering type of the present utility model according to the above---the siphon fluid filling pump.
Claims (2)
1. a filtering type is manual---the siphon fluid filling pump, the structural design that it is characterized in that this pump inlet one-way valve is the unsteady valve block (1) of lightweight to be put into the valve port chamber of lower cover (14), cover spacing net (2), use set screw (3) to be fixed on the lower cover (14) again, filter (7) is housed on drain pipe (6) in addition.
2. manual according to right 1 described filtering type---the siphon fluid filling pump is characterized in that the unsteady one-way valve of being made up of the unsteady valve block (1) of lightweight, spacing net (2), set screw (3) and lower cover (14).
