Description

Liquid guiding pump

The utility model relates to liquid transporting device, specifically a kind of Liquid guiding pump.

We know that oil, chemical industry and car and boat carrier transporting oil or liquids such as acid, alkali often need special instrument.At present, how to adopt a conducting tube simply,, will be in high-order liquid importing by siphonage and be in the container of position, the end, during use, fluidsupply container must be placed a high position by potential difference; Common pumping cylinder drives a piston of being with one-way valve by a handle, and liquid is extracted out from fluidsupply container, discharges from liquid outlet, and this pumping cylinder blow-by is used easily to pollute, and is dangerous; A kind of Liquid guiding pump is abroad arranged, be made up of the pump housing, piston, one-way valve, slotted link mechanism, liquid inlet pipe, drain pipe, one-way valve is located at the piston bottom, and piston links to each other with slotted link mechanism.When fluidsupply container is in a high position, reliable siphonage drain, when fluidsupply container was in low level, by operator's push-and-pull slotted link mechanism, the drive piston pumped and reaches the purpose of drain.After this Liquid guiding pump drain finishes, have residual liquid in the pump, both wasted, may pollute again, bring danger, must pour out from drain pipe carefully, use inconvenience, it is suitable for Oil Guide in addition, can not lead corrosive liquids such as acid, alkali.

The purpose of this utility model is in order to overcome the deficiency of above-mentioned drainage set, the manufacturing of a kind of employing new material to be provided, and processing is simple, and is applied widely, and residual liquid can be put back to former container, safe in utilization, Liquid guiding pump easily.

For achieving the above object, a kind of Liquid guiding pump is provided with piston, one-way valve, slotted link mechanism, pump cover, pump barrel, liquid inlet pipe, drain pipe, one-way valve is located at the piston bottom, piston links to each other with slotted link mechanism, it is characterized in that the pump barrel lower end also is provided with a tapping device, the flat axle of this device passes from the hole of an one-way valve, is horizontally set with in pump barrel.

The said one-way valve of the utility model is " ten " font cylinder that has round cap, and the centre is provided with a square hole.The jointing of said liquid inlet pipe and pump barrel can also be equipped with filter screen.

Whole parts of the present utility model adopt poly-carbon ester plastic processing, and easy processing both can be used to Oil Guide, can lead liquid such as acid, alkali again, and the residual solution in the pump can be put back to former fluidsupply container by the tapping handle, and is easy to use, safe and reliable.

Below in conjunction with accompanying drawing embodiment of the present utility model is done detailed description:

Fig. 1 is a structural representation of the present utility model, also is embodiment's schematic representation.

Label among the figure is: handle 1, main shaft 2, jackscrew 3, connecting rod 4, little axle 5, support 6, piston 7, seal ring 8, one-way valve 9, one-way valve 10, filter screen 11, seal ring 12, pump cover 13, bleed valve 14, drain pipe 15, seal ring 16, pump barrel 17, seal ring 18, tapping handle 19, locking nut 20, liquid inlet pipe 21.

As can be seen from the figure, this Liquid guiding pump is mainly by pump cover 13, pump barrel 17, and slotted link mechanism, piston 7, one-

way valve

9,10, tapping handle 19 and liquid inlet pipe 21, drain pipe 15 is formed.Pump cover 13 is provided with bleed valve 14 and drain pipe 15, and the effect of bleed valve is to control transfusion situation when utilizing the siphonage drain, after promptly drain is finished, unscrews bleed valve 14, and drain can stop automatically.Pump barrel 17 is round funnel shape, and upper end and pump cover 13 connect sealing by screw thread and jackscrew 3 etc., and the lower end is communicated with by locking nut 20 and liquid inlet pipe 21, and the centre respectively is provided with seal ring 16 and seal ring 12.Slotted link mechanism is provided with handle 1, main shaft 2, connecting rod 4, little axle 5, support 6, main shaft 2 is installed in the pump cover 13, connecting rod 4 one ends link by spiral shell and are connected on the main shaft 2, the other end is connected with support 6 by little 5, handle 1 is gone into main shaft 2 from the pump cover extrapolation, shake handle 1 and can make main shaft 2 to-and-fro motion, drive support 6 and pump, reach the purpose of push-and-pull piston 7.Support 6 is connected with piston 7, is with a seal ring 8 around the piston 7, and the bottom is provided with a center hole, and an one-way valve 9 is housed in the hole.One-way valve 9 can be up and down in the hole, when piston moves downward, one-way valve 9 relatively upwards slides, and freely opens the slit with center hole, comes on following liquid or the air stream, and when piston 7 moves upward, one-way valve 9 moves downward relatively, shuts center hole, the drain pipe 15 that piston 7 is pushed the liquid or the air on its top to pump cover, the liquid of piston 7 bottoms is put on by the atmospheric pressure difference simultaneously, moves the vacuum that causes on the piston to remedy.Also be provided with an one-way valve 10 in the pump barrel lower end, its effect is to guarantee the liquid upper reaches, prevents when piston presses down, and the liquid in the pump is pressed to fluidsupply container.One-way valve the 9, the 10th, top has the slide block of round cap, and in order to save material, this Liquid guiding pump is processed into slide block the cylinder of " ten " type, and the centre is provided with a square hole.One-

way valve

9,10 is by poly-carbon ester plastics single injection-molded, the diameter of its circle cap is more bigger than the internal diameter of the center hole internal diameter of piston 7 and pump barrel lower end pipe, the diameter of " ten " font cylinder is more smaller than the internal diameter of center hole internal diameter and pump barrel lower end pipe, can guarantee being free to slide of one-way valve like this.

Tapping handle 19 is located at the pump barrel lower end, which is provided with a flat axle, and it passes from the square hole of one-way valve 10, is horizontally set with in pump barrel.Tapping handle 19 passes from the square hole of one-way valve 10, plays a part on the one hand to limit one-way valve 10 the sphere of activities, and promptly tapping handle 19 flat axles are horizontal, and the sphere of activities of restriction one-way valve 10 guarantees one-way valve 10 proper functioning, and the unlikely pump barrel of falling into; Play the tapping effect on the other hand, promptly after drain finishes, piston 7 is pressed onto bottom, at this moment, one-way valve 9 contacts with pilot valve 10, the tapping handle rotates 90 °, makes the plane of flat axle be in vertical position, and can contact with the square hole upper edge of one-way valve 10 like this, promotion one-way valve 10, one-way valve 9 move up, round cap on the one-way valve leaves corresponding contact position, and liquid flows down automatically, puts back to fluidsupply container.The outer end of tapping handle 19 is provided with seal ring 18, and to seal, liquid does not outflow, and is air tight.

This Liquid guiding pump liquid inlet pipe 21 can be connected with pump barrel 17 by locking nut 20, and at its jointing filter screen 11 and seal ring 12 is housed, in case during drain in the impurity inflow pump.

When utilizing this Liquid guiding pump drain, drawing handle 1, it is up and down to drive piston 7, and liquid constantly elevates by one-

way valve

9,10, discharges from drain pipe 15.When fluidsupply container is in a high position, after this, no longer need drawing handle 1, can continue drain by siphonage, after finishing, unscrew bleed valve 14, can stop drain; When if fluidsupply container is in low level,, can continue drain so that drain finishes by continuous drawing handle 1.Then unscrew bleed valve and rotate tapping handle 19, the residual liquid in the pump can be put back to former fluidsupply container, easy to use, safe and reliable.

This Liquid guiding pump can all adopt poly-carbon ester plastic processing, and easy processing promptly can be used to Oil Guide, can lead corrosive liquids such as soda acid again, owing to adopt the tapping device, and esy to use, safe and reliable.
