Abstract
The utility model relates to a manual liquid pump for liquid extractors. A push-pull rod, an oil discharge pipe, a pump bonnet, an oil inlet valve, an oil inlet valve seat and an oil inlet cap are fixed on an upper barrel and a lower barrel. A semi-cylindrical shunting piston with an oil outlet valve is fixed on the push-pull rod. The lower barrel is divided into two parts, and the oil discharge pipe is fixed in a guide sleeve. Because of the function of the shunting piston, the oil inlet valve and the oil outlet valve, liquid is continuously output from the oil discharge pipe during the entire pumping and pressing cycle period. The manual liquid pump is made of plastic fully, and the manual liquid pump is light and convenient with strong universality, and therefore, the manual liquid pump is suitable for filling various kinds of oil for tractors, automobiles, boats, combustion engines, etc. and suitable for discharging water in small cabins, and the utility model is especially suitable for filling various corrosive liquids such as acid, alkali, amine and benzene in factories, warehouses, chemical engineering industry and electric plating industry.
Description
The utility model relates to a kind of liquid suction, manually liquid sorption pump.
Now for making things convenient for the relevant manual liquid suction patent of drawing liquid of a great variety, have their own characteristics each, CN2036216U " hydrocone type liquid transfer device ", CN2067329U " handle type liquid filler " etc. has a common drawback, when making progress drawing liquid, there is liquid to export, and when pressing down, just do not have liquid output, take out at one and press in the cycle period through oil outlet tube, have only half period in work, liquid output is discontinuous intermittent.
The purpose of this utility model is to provide a kind of manual liquid sorption pump, its simple in structure whole take out to press in the cycle period all have liquid from oil outlet tube, to export, be specially adapted to for transfusion continuously use in all kinds of perishable liquid such as electroplating industry and acid, alkali, amine, benzene.
The utility model is achieved in that pull bar, pump cover, oil outlet tube, oiling valve, oil-feed valve seat, feed cover all are fixed in the upper and lower tube, and the half round post shunting piston that also fixedly has outlet valve on the pull bar, doffing is divided into two parts, and oil outlet tube is fixed in the guide pin bushing.By the shunting piston and into and out of the effect of fuel tap make its whole take out to press in the cycle period all have continuous liquid from oil outlet tube, to export.
Fig. 1 is the utility model structural representation.
Fig. 2 a, 2b are the utility model working procedure schematic representation.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
This liquid sorption pump all adopts plastic materials to make, adopt the glassie of φ 20 into and out of fuel tap (9), (8), oil outlet tube (4) adopts φ 20 snakelike soft plastic pipes, oil outlet tube (4) muzzle has double end sealing plug (12), oil outlet tube (4) end is fixed in the guide pin bushing (5), and guide pin bushing (5) is fixed on the annular convex rib of doffing (7) upper end with the hot jacket method.
Pump cover (2) has outside thread for hexagon female cap periphery, and intermediate throughholes is passed pull bar (1), and the next door through hole passes oil outlet tube (4) next door and also has a return-air hole, on the upper and lower sidewall of top cylinder (3) free vent is arranged respectively.There is the disymmetrical protruding end that is fixed on top cylinder (3) with hot melt of taking doffing (7) upper end, pull bar (1) end thread is fixed on the semi-cylindrical shunting piston (6), one overhanging semicircle is arranged at shunting piston (6) bottom, through hole is arranged in the middle of the semicircle and close valve rod, oil-feed valve seat (10) is fixed with the terminal hot melt of doffing (7).Feed cover (11) sidewall periphery has long grid hole to make the impurity that is deposited in the bottom be difficult for rising from horizontal oil-feed, guarantee the turbidity test of oil, be fixed on oil-feed valve seat (10) bottom with hot melt, put respectively on the through hole that is placed on oil-feed valve seat (10) and shunting piston (6) bottom turnover fuel tap (9), (8).
Open oil drum cap during use pump is inserted in the oil drum, make pump cover (2) be spun on the oil drum cap fixing with screw thread.Upwards spur pull bar (1), oiling valve shown in Fig. 2 a (9) is opened automatically, make the interior full of liquid oil of doffing (7), simultaneously outlet valve (8) cuts out and begins outside oil transportation, again to pressing down pull bar (1), automatically open as the shown fuel tap of Fig. 2 b (8), oiling valve (9) cuts out voluntarily, because the effect of shunting piston (6) makes the constantly output from oil outlet tube (4) of the interior oil of doffing (7), reach upwards, moving down pull bar (1) Shi Douhui has oil to extract out to reach the purpose of continuous oil transportation, and the siphon oil transportation is the same with prior art does not voluntarily describe in detail as long as there are 20 cm height differences to treat need not spur after fuel-displaced pull bar (1).As long as making the capital of closing in shunting piston (6) lives in fuel tap (9) siphon and promptly stops.
During as if effumability liquid such as draw gas with this pump oil, oil of bananas, the little plug on the double end sealing plug (12) can be clogged the return-air hole on the pump cover (2) after using, clog oil outlet tube (4) mouth greatly, avoid evaporating.
This manual liquid sorption pump is overall plastic, simple in structure, adopt the shunting piston, during work not only lightly but also can infuse continuously, price is low, adaptability, highly versatile, the can that is applicable to all kinds of oil such as tractor, automobile, small boat, internal-combustion engine is used, and also can be used for the draining of canoe storehouse and uses, and the can that is specially adapted to factory position warehouse, chemical industry, electroplating industry, acid, alkali, amine, all kinds of corrosive liquids such as stupid is used.
Claims (5)
1, a kind of manual liquid sorption pump, form by pull bar (1), pump cover (2), tube, oil outlet tube (4), oiling valve (9), oil-feed valve seat (10), feed cover (11), it is characterized in that pull bar (1) upward fixedly has the shunting piston (6) of outlet valve (8), oil outlet tube (4) is fixed in the guide pin bushing (5).
2, liquid sorption pump according to claim 1 is characterized in that pull bar (1) utilizes end thread to be fixed on the half-cylindrical shunting piston (6), and an overhanging semicircle is arranged at shunting piston (6) bottom, through hole is arranged in the middle of the semicircle and close valve rod.
