Abstract
The utility model discloses a gas-liquid pump. The gas-liquid pump comprises a cylinder body, a piston, an upper end cover, a lower end cover, an air valve, a liquid inlet valve and a liquid outlet valve, wherein the piston is positioned in the cylinder body, and is in sealed sliding fit with the inner wall of the cylinder body; the upper end cover and the lower end cover are respectively connected to the upper end and the lower end of the cylinder body in a sealing manner; the air valve is arranged on the upper end cover and is communicated with an inner cavity of the cylinder body; the liquid inlet valve and the liquid outlet valve are arranged on the lower end cover and are communicated with the inner cavity of the cylinder body. The gas-liquid pump has the advantages that low-pressure liquid is accumulated in an lower part space formed by dividing the cylinder body by the piston through the liquid inlet valve, after the low-pressure liquid is accumulated to a certain extent, the liquid inlet valve is closed, the liquid outlet valve is opened, under the air pressure of an upper part space, the piston moves downward to extrude the liquid out, and the pressure of the extruded liquid can be adjusted by adjusting the air pressure in the upper part space to meet the requirements of pressure and flow.
Description
Technical field
The utility model relates to a kind of gas-liquid mixed power switching device, particularly a kind of Gas-liquid pump.
Background technique
The liquid pump is that the transformation of energy with prime mover is the device of liquid energy, existing liquid pump mostly adopts motor or internal-combustion engine as prime mover, transformation of energy by prime mover, the low pressure liquid high pressure is exported, but when the fluid flow that enter the liquid pump hour, prime mover is all the time in acting, can not adjust voluntarily according to operating mode, and output fluid pressure does not reach both provisioning requests, cause a large amount of energy wastes, if original machine power is less simultaneously, and the acting parts often can not satisfy the demands inefficiency when higher to fluid pressure and traffic demand very soon, drive large tank such as little oil pump, perhaps The Wash needs big-flow high-pressure water to carry out the vehicle flushing in the carwash process can not to satisfy the demands simultaneously.
The model utility content
Technical problem to be solved in the utility model provides a kind of Gas-liquid pump, can increase work efficiency according to the oil cylinder demand for its hydraulic oil that corresponding discharge and pressure are provided.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of Gas-liquid pump comprises cylindrical shell, piston, upper end cap, lower end cap, air valve, feed liquor valve and liquid valve; Described piston place in the cylindrical shell and with the cylinder inboard wall sealed sliding movingly; Described upper end cap and lower end cap are tightly connected with the cylindrical shell top and bottom respectively; Described air valve is located on the upper end cap and with cylinder lumen and is communicated with; Described feed liquor valve and liquid valve are located on the lower end cap and with cylinder lumen and are communicated with.
Described piston circumference is provided be used to the annular slot that holds O-ring seal, and O-ring seal is installed in the groove.
Described piston adopts the rubber material, its circumference be provided with for the annular projection of cylinder inboard wall sealing.
Described upper end cap is connected with cylinder screw respectively with lower end cap.
The beneficial effect that adopts technique scheme to produce is: sealing is slided piston is set in cylindrical shell, piston is divided into two spaces up and down with cylinder lumen, upper space is communicated with air valve, lower space is communicated with feed liquor valve and liquid valve, in upper space, inflate, certain air pressure can be provided, and lower space is liquid container, and the intermittently folding of feed liquor valve and liquid valve, in lower space, accumulate low-pressure liquid by the feed liquor valve, after running up to a certain degree, close the feed liquor valve, open liquid valve, under the upper space air pressure, piston moves downward, liquid is outwards extruded, and the fluid pressure of extrusion can be adjusted by adjusting the upper space gas pressure, to adapt to pressure and traffic demand.

Fig. 1 is the utility model structural representation;
In the accompanying drawings: 1, upper end cap; 2, cylindrical shell; 3, piston; 4, lower end cap; 5, liquid valve; 6, feed liquor valve; 7, air valve.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The utility model discloses a kind of Gas-liquid pump, comprises cylindrical shell 2, piston 3, upper end cap 1, lower end cap 4, air valve 7, feed liquor valve 6 and liquid valve 5; Described piston 3 places in the cylindrical shell 2 and with cylindrical shell 2 inner wall sealings and is slidingly matched; Described upper end cap 1 and lower end cap 4 are tightly connected with cylindrical shell 2 top and bottom respectively; Described air valve 7 is located on the upper end cap 1 and with cylindrical shell 2 inner chambers and is communicated with; Described feed liquor valve 6 and liquid valve 5 are located on the lower end cap 4 and with cylindrical shell 2 inner chambers and are communicated with, and use for convenience, air valve 7 can also be located on the cylinder lateral wall, only need guarantee that it is communicated with cylindrical shell 2 upper spaces that are divided into by piston 3 to get final product.
Described piston 3 circumference are provided be used to the annular slot that holds O-ring seal, and O-ring seal is installed in the groove; Piston 3 can also be used for reference the piston structure of disposable syringe, adopts the rubber material, and at its circumference circular protrusion formation sealing is set.
Described upper end cap 1 and lower end cap 4 are threaded with cylindrical shell 2 respectively, also can adopt the bonding or welding of adhesive, only need to satisfy fixing and sealing function getting final product.
In concrete application process, at first inject the gas of certain pressure from air valve 7, under the effect of gas pressure, piston 3 is descending, the size of air pressure is determined according to the pressure of liquid needs, under the little situation of the big flow of pressure of liquid, injects liquid from feed liquor valve 6, injecting the liquid process, liquid valve 5 is closed, and under fluid pressure, piston 3 slowly rises, the gas of extruding upper space, form big pressure, treat that fluid pressure reaches after the certain value, opens liquid valve 5, it is descending that this moment, pressurized gas promoted piston 3, form the liquid output of high-pressure high-flow, solved the problem that high-pressure low-flow is become the output of high-pressure high-flow liquid, be suitable for the water that The Wash provides high-pressure high-flow, be the equipment improvement of little oil pump large tank, satisfy the large tank work requirements.
