Abstract
The utility model discloses a manual oil-well pump comprising a pump body, a sucking pipe and a discharging pipe. The sucking pipe is connected with the pump body horizontally, and the discharging pipe is connected with the pump body vertically. A spool is arranged on the pump body opposite to the sucking pipe. An outer housing connected with the pump body in a sealing manner is arranged outside the spool, and is connected with an operating rod which is provided with a gas check valve bonnet. A valve block a and a valve block b are vertically arranged in the pump body. The valve block a is flexibly connected to an outlet port of the sucking pipe, and the valve block b is flexibly connected to an inlet port of the discharging pipe. The operating rod moves up and down to drive the valve block a and the valve block b of the pump body to open and close alternately so as to complete liquid sucking and prevent the liquid from flowing back; thus, Siphon effect, automatically pumping or discharging steps are achieved, and the liquid can be pumped by simple operating acts; and the manual oil-well pump has the advantages of light weight, high efficiency, labor saving, wide application range and environment-friendliness, and is adaptable to water, oil, chemical and acid and alkali resistant solutions.
Description
Technical field
The utility model belongs to all kinds of Liquid extractings and conversion equipment, particularly a kind of manual oil well pump.
Background technique
Manually oil well pump is a kind ofly to be usually used in water for the instrument of extracting liquid from liquid holding container out, oil, chemical industry class, the extraction of soda acid liquid etc., conversion.
Existing hand oil pump mainly is the cast iron moulding, and is bulky and heavy, and complex structure is not easy to operate, acid resistant alkali not, and not environmental protection, usage range is limited, and practicability has much room for improvement.
The model utility content
The purpose of this utility model provides a kind of manual oil well pump in light weight, easy and simple to handle simple in structure.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of manual oil well pump, comprise the pump main body, level be connected on the pump main body suction pipe and vertically to the output tube that is connected on the pump main body, the pump main body is provided with and the rightabout spool of suction pipe, described spool is provided with outward and the airtight outer cover that is connected of pump main body, be connected with operating stem on the outer cover, operating stem is provided with the nut of holding one's breath, be provided with orthogonal valve block a and valve block b in the described pump main body, described valve block a is movably connected in the outlet port of suction pipe, and described valve block b is movably connected in the ingress of output tube.
Wherein, described pump main body is provided with and is positioned at the outer screw of suction pipe.
In addition, described screw is the standard oil bung adaptive with the oil drum opening.
The beneficial effects of the utility model are: by the operating stem knee-action, get final product the alternately folding of the interior valve block a of driven pump main body and valve block b when this oil well pump uses, finish suction liquid successively, prevent that liquid from refluxing, thereby reach siphon effect, the step of Automatic Extraction or discharge liquid, only need simple motion action can extract liquid, have in light weight, efficient, the labour-saving advantage, and be applicable to water, oil, chemical industry class, acid resistant alkali solution, using scope is extensive, environmental protection.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 to Fig. 5 is working principle schematic representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to shown in Figure 1, the utility model discloses a kind of manual oil well pump, comprise pump main body 1, level be connected on the pump main body 1 suction pipe 2 and vertically to the output tube 3 that is connected on the pump main body 1, pump main body 1 is provided with and suction pipe 2 rightabout spools 4, described spool 4 outer being provided with and the pump main body 1 airtight outer cover that is connected 5, be connected with operating stem 6 on the outer cover 5, operating stem 6 is provided with the nut 7 of holding one's breath, be provided with orthogonal valve block a11 and valve block b12 in the described pump main body 1, described valve block a11 is movably connected in the outlet port of suction pipe 2, described valve block b12 is movably connected in the ingress of output tube 3, described pump main body 1 is provided with the screw 8 that is positioned at outside the suction pipe 2, and described screw 8 is the standard oil bung adaptive with the oil drum opening.
During use, close the nut 7 of holding one's breath earlier, this oil well pump is put into oil drum, screw in oil drum cap and mounted pump main body 1 by screw 8, then spool 4 is upwards extracted out, pump main body 1 interior valve block a11 opened and sucked liquid this moment, and valve block b12 sealing, prevent that by holding one's breath liquid from refluxing, and finishes the suction step as shown in Figure 2.
Press down spool 4 then, valve block a11 sealing prevent that by holding one's breath liquid from refluxing, and valve block b12 is opened suction liquid, finishes the extrusion step as shown in Figure 3.
This moment spool 4 motionless one-tenth natures, valve block b12 opens discharge liquid, and valve block a11 opens suction liquid, form vacuum state in the entire pump main body 1 this moment, liquid is extracted out automatically, finishes the self-priming step as shown in Figure 4.
Outward winding nut 7 back of holding one's breath becomes the natural inflow states, and valve block a11 becomes the nature open mode to finish to extract and stops with valve block b12, and as shown in Figure 5, the screw 8 on the oil drum of outwarding winding this moment gets final product manual oil well pump.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
