Abstract

The utility model relates to a semi-automatic liquid pumping device. A liquid pumping pipe and an air inlet pipe are both arranged on a screw cover on the mouth of a liquid containing vessel; air inlet valve is a three-way valve; upper side is also provided with a safety valve; so excessive compressed air can be automatically removed; air conduction can be controlled, and siphon automatic liquid pumping is achieved. The utility model can pressurize and fetch liquid by adopting compressed air source, or pumps liquid with the mode of siphon. The utility model has the advantages of stable operation, convenient operation, labour saving and high efficiency, and the phenomenon of spreading and leaking when the liquid is pumped can be effectively prevented.

Description

Semi-automatic liquid pump

The utility model relates to a kind of pumping device.

Existing pumping device is centrifugal manual pumping device mostly, and effort and very inconvenient easily spills liquid during use.

The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and a kind of laborsaving efficient and semi-automatic easily liquid suction is provided

The utility model includes pumping pipe and valve, suction tude, suction valve and spiral cover.Suction valve directly connects source of the gas, and valve is housed on the pumping pipe, is used to control the pumping pipe break-make.Suction tude and pumping pipe all are loaded on the spiral cover, and the spiral cover periphery has screw thread, can directly be screwed on the liquid container mouth.

During use, suction valve is connected source of the gas, feed pressurized air through suction tude in liquid container, liquid is flowed out by pumping pipe under gas pressure.In order to exclude excessive pressurized air, suction valve adopts three-way valve, safety valve is housed above, so that excess compressed air excludes automatically.

Safety valve includes valve body, valve gap, piston, pull bar and spring, have pore on the valve body, valve body directly is loaded on the three-way valve by screw socket, piston, pull bar and spring are housed in the valve body, spring is loaded between piston and the valve gap, tune just adjustable springs pressure of valve gap, and then air pressure in the regulation and control container.The piston normal condition is in closed condition, as the liquid container internal air pressure when too high, but jack-up valve body inner carrier, pore is discharged on valve body.The pull bar external part stretches out from valve gap, also has a joint on the pull bar.Higher as the liquid container position, when wanting to adopt the automatic drawing liquid of siphon, but pull-up pull bar and at the pull bar joint several angle of turning back makes that pore is in opening state on the valve body, just air can enter in the liquid container through suction tude, realizes the automatic drawing liquid of siphon.

Safety valve also can adopt gravity-type outlet valve or other structural type.

Below in conjunction with description of drawings:

Accompanying drawing is the utility model structural representation.

Among the figure: 1, valve, 2, pumping pipe, 3, adjust nut, 4, spiral cover, 5, suction tude, 6, suction valve, 7, piston, 8, pull bar, 9, valve gap, 10, the joint, 11, spring, 12, valve body, 13, pore.

Also be equipped with one and adjust nut 3 on the pumping pipe above the spiral cover 42, its effect is the orientation that is used to regulate pumping pipe 2.

The utility model can be used for extracting gasoline, diesel oil, machine oil, reaches edible wet goods liquid, and used source of the gas can be a source of compressed air, small-sized air compressor, treadle air pump, hand air pump etc.Laborsaving efficient, applied widely, stable and reliable working performance, easy to operate, and under the conditions permit situation, also can adopt the automatic drawing liquid of siphon mode, and spill phenomenon can effectively prevent drawing liquid the time.To utilizing the automobile of gas brake, the utility model can utilize also that source of the gas comes to the vehicle rapid refueling on the car.
