CN203098223U - Small-type oil-well pump - Google Patents

Abstract

The utility model discloses a small-type oil-well pump which comprises a pump body, a suction pipe, an output pipe and a valve core, wherein the valve core and the suction pipe are respectively connected on the upper side and the lower side of the pump body respectively, the output pipe is horizontally connected on the pump body, an operation rod is arranged at the top of the valve core and is provided with a closed screw cap, a transverse valve slice and a longitudinal valve slice are arranged inside the pump body in sequence, the transverse valve slice is located at the position of an outlet of the suction pipe, and the longitudinal valve slice is located at the position of an inlet of the output pipe. When the small-type oil-well pump is used, the closed screw cap is firstly screwed tightly, the valve core is pinched by a hand for 3-5 times, therefore, alternate opening and closing of the transverse valve slice and the longitudinal valve slice in the pump body can be driven, and the steps of sucking liquid, preventing the liquid from backflow and draining the liquid can be finished in sequence. The closed screw cap is loosened and the operation is stopped. The liquid can be pumped only by easy action operation. Meanwhile, the small-type oil-well pump has the advantages of being light in weight, efficient and labor-saving.

Description

A kind of small-sized oil well pump

Technical field

The utility model belongs to Liquid extracting and conversion equipment, particularly a kind of small-sized oil well pump.

Background technique

Hand oil pump is a kind of instrument that is used for extracting out from liquid holding container liquid, is usually used in water, 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 small-sized 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 small-sized oil well pump, comprise pump main body, suction pipe, output tube and spool, described spool and suction pipe are connected to the upper and lower both sides of pump main body, described output tube level is connected on the pump main body, described spool top is provided with operating stem, the nut of holding one's breath is installed on the operating stem, is provided with horizontal valve block that is positioned at the suction pipe outlet port and the vertical valve block that is positioned at the output tube ingress in the described pump main body successively.

The beneficial effects of the utility model are: tighten the nut of holding one's breath when this oil well pump uses earlier, with hand pinch spool 3-5 times, vertical valve block in can the driven pump main body with and the laterally alternately folding of valve block, finish suction liquid successively, prevent liquid return, the step of drain, back-outing the nut of holding one's breath can quit work, only need simple motion action can extract liquid, have advantage in light weight, high-effective and labour-saving.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 to Fig. 5 is a 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 small-sized oil well pump, comprise pump main body 1, suction pipe 2, output tube 3 and spool 5, described spool 5 and suction pipe 2 are connected on the pump main body 1, following both sides, described output tube 3 levels are connected on the pump main body 1, described spool 5 tops are provided with operating stem 6, the nut 7 of holding one's breath is installed on the operating stem 6, be provided with horizontal valve block 12 that is positioned at suction pipe 2 outlet ports and the vertical valve block 11 that is positioned at output tube 3 ingress in the described pump main body 1 successively, during use, close the nut 7 of holding one's breath earlier, this oil well pump is put into oil drum, use hand pinch spool 53-5 times then, can the driven pump main body in 1 vertical valve block 11 with and the laterally alternately folding of valve block 12, as Fig. 2, Fig. 3, Fig. 5 and shown in Figure 5 finishes suction liquid successively, prevents liquid return, the step of drain, back-outing the nut 7 of holding one's breath can quit work, and only needs simple motion action can extract liquid, has in light weight, the advantage of high-effective and labour-saving.

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.
