Abstract
The utility model relates to an air cylinder or an air pump applied to positive pressure and negative pressure, wherein an inflator pump and a vacuum pump are integrated; in order to reduce the shortage of simultaneously purchasing and carrying a pressurizing air cylinder or a pressurizing pump and a vacuum pump, the utility model provides a scheme and a device which are aimed at realizing the purpose of air extraction and high-pressure air inflation by implementing air suction and air exhaust according to the two strokes of air inlet and air exhaust, and the air suction and the air exhaust are carried out by moving a piston up and down. The air cylinder or an air pump applied to positive pressure and negative pressure provided by the utility model is characterized in that the bottom part outside a lower piston dead point of an inflating pump or a vacuum pump is equipped with two air holes and is equipped with two one-way air valves which are opposite in the direction so as to form an air suction pipeline and a high-pressure air exhaust pipeline, the air suction pipeline can be used for sucking the air within the container to be exhausted, and the high-pressure air exhaust pipeline can be used for implementing high-pressure air inflation to the other container to be inflated, so that the air cylinder or an air pump applied to positive pressure and negative pressure provided by the utility model is a dual-purpose tool with the function of a vacuum pump and the function of a pressurizing air cylinder or a pressurizing pump.
Description
Affiliated technical field:
The present invention relates to a kind ofly in cylinder, move and two Non-return air valves carry out the method and apparatus that high-pressure aerated and extraction or draw gas function are integrated with piston.
Background technique:
At present, in the industry or the place of the gas of need annotating to some, all carry out with adding pneumatic tube or adding compression pump; Extracting some or the industry or the place of draw gas, all be to realize work with manual or motor-driven vacuum pump; Add pneumatic tube or add compression pump and vacuum pump must be bought respectively, use respectively; Need at the same time to use or same unit needs use respectively when adding pneumatic tube or compression pump and vacuum pump, need purchase respectively to add pneumatic tube or compression pump and vacuum pump; During operation in the open air, need carry two instruments simultaneously, very inconvenient.
Summary of the invention:
1, two pores are offered in the bottom beyond the piston lower dead center of pump or high-pressure pump, press opposite direction respectively on two pores a Non-return air valve door (7) (8) is installed.
2, on two air valves, connect a high-pressure air pipe (9), (10) respectively, connect the interface of needs at the tip of two tracheaes separately.
Description of drawings:
Figure of description is " positive and negative pressure dual-purpose inflator or air pump " schematic representation, among the figure 1, Joystick; 2, piston rod; 3, air cylinder cover; 4, air cylinder body; 5, piston; 6, cylinder cavity; 7, breather cheek valve door; 8, inflation one-way cock; 9, aspirating air pipe; 10, gas ducting; 11, inflator base.
Embodiment:
The scheme that the present invention solves its technical problem is; Bottom beyond the piston lower dead center of a pump or inflating pump, offer two pores, on two pores, a Non-return air valve door (7), (8) are installed respectively according to opposite direction, on two air valves, connect a high-pressure air pipe (9), (10) respectively, connect the interface of needs at the tip of two tracheaes separately.During implementation, piston (5) moves up, and forms an intake stroke, utilizes aspirating air pipe (9) just can draw gas in the container that needs exhaust; Piston (5) moves down, and forms an exhaust stroke, utilizes the high pressure gas pipeline just can inflate another container that need inflate; Like this, just formed a vacuum pump that has the draw gas function simultaneously and pressurized air and needed the gas container of aerating to carry out the pump or the high-pressure service pump of aerification function, two instruments of difference in functionality have been synthesized an integral body another.
Beneficial effect of the present invention:
1 do not change the general structure of inflator or high-pressure pump and vavuum pump, only increased the pressure piping of an air inlet or exhaust;
2 have reduced the purchase cost of buying simultaneously inflator or high-pressure pump and vavuum pump;
Or else need to carry simultaneously pump and two instruments of vacuum pump during 3 uses, use more convenient;
4 are connected piston rod with other mechanical device, just form a dual-purpose air pump of motor-driven positive and negative pressure.
Claims (2)
1. positive and negative pressure dual-purpose inflator or air pump is characterized in that; Two pores are offered in bottom beyond the piston lower dead center of pump or high-pressure pump, press opposite direction respectively on two pores a Non-return air valve door (7) (8) is installed.
2. positive and negative pressure dual-purpose inflator according to claim 1 or air pump is characterized in that; On two air valves, connect a high-pressure air pipe (9), (10) respectively, connect the interface of needs at the tip of two tracheaes separately.
