Abstract
The utility model relates to an oil adding and pumping appliance, which is composed of a main body 1 and a ventilating nut 4. An air gate one-way valve plate 2 and a wave-shaped cushion ring 3 are arranged between the main body 1 and the ventilating nut 4. The work of pumping oil is achieved by means of definite external force action by adopting the method of one-way air flow passing and inverted air flow closing. The utility model has the advantages of simple structure and easy use, convenient operation, portability, easy fabrication and low cost. The utility model is suitable for various oil pipes with different specifications of pipe diameters.
Description
The utility model relates to the utensil that the driver refuels or pumps, particularly a kind of self-priming oil pumping mouth.
Big to being divided into electronic oil-sucker in existing oil-sucker, machinery oil-sucker and self-flow type oil-sucker, it is complicated that the former two all belongs to manufacturing, and technical difficulty is big, and limited by certain specific condition, use inconvenience, and the self-flow type oil-sucker is just being accepted by people, but this type of oil-sucker kind is more, mostly all to design complexity, machinery is various, makes to be difficult for, and can not be accepted by people.
The purpose of this utility model is at the deficiencies in the prior art, and provide a kind of simple in structure, easy to use, not limited by environmental conditions, the utilization one-way gas flow is passed through, and the method that back draught is closed relies on certain external force effect to finish the self-priming oil pumping mouth of oil pumping work.
The concrete technological scheme that realizes the utility model purpose is: the oil pumping mouth is by main body, and the ventilation nut is formed, and between main body and ventilation nut one valve check valve sheet and wave washer is arranged; The valve check valve sheet be pad on main body, the wave washer pad on the valve check valve sheet, the main body and the scyewed joint between nut of ventilating.
The utlity model has simple in structurely, easy to use, be easy to carry, make advantages such as easy processing, be suitable for the oil pipe of various different size calibers.
Fig. 1 is the utility model structural representation,
Fig. 2 is a sectional drawing of the present utility model.
In the accompanying drawing: 1-main body, 2-valve check valve sheet, 3-wave washer, the 4-nut of ventilating.
The oil pumping mouth is connected with an end of oil pick-up tube, the other end of oil pick-up tube inserts by in the drawing liquid body, at this moment the interior valve check valve sheet 2 of mouth of pumping is boosted, because the external diameter of valve check valve sheet 2 is less than the internal diameter of ventilation nut 4, air is discharged through the pore of ventilation nut 4 by space on every side, when not leaving liquid level when oil pick-up tube is upwards drawn, air in the pipe is walked downwards, valve check valve sheet 2 in the oil pumping mouth is close on the main body 1 by the air of coming in from the pore of ventilation nut 4, thereby air-flow path is closed, liquid can't reflux, pull oil pick-up tube up and down so repeatedly will full of liquid in the oil pipe, and the mouth of will pumping is at last pulled up, liquid will flow out automatically, finishes its work.
Claims (2)
1, a kind of self-priming oil pumping mouth, by main body 1, ventilation nut 4 is formed, and it is characterized in that main body 1 and 4 on nut of ventilation have a valve check valve sheet 2 and wave washer 3.
2, oil pumping mouth according to claim 1 is characterized in that valve check valve sheet 2 is to fill up on main body 1, and wave washer 3 fills up on valve check valve sheet 2, main body 1 and 4 scyewed joint of ventilation nut.
