Abstract
The utility model relates to an improved dual-purpose inflator capable of pumping air, which not only can be used for making up air, but also can be used as a hand-driven air pump. An air outlet one-way valve 1 and an air suction one-way valve 4 are arranged on a base of a cylinder body 2. A cylinder piston 3 is a bi-directional sealing piston, and can freely move up and down in the cylinder body 2. According to the different purposes of inflation or air suction, an air pipe 6 is connected with the air outlet one-way valve 1 or the air suction one-way valve 4 by a special clamp 5 of the air pipe. When sucking air, the other end of the air pipe 6 is connected with a vacuum switch 7 by the special clamp 5 of the air pipe.
Description
The utility model relates to a kind of follow-on dual-purpose pump of bleeding, it be existing inflate to improve on the simple radical plinth form, both can be used to make-up gas, can be used as the manual suction pump use again.
The pump that uses at present is single acting piston, disposes a gas outlet valve, can only be as inflating the usefulness of make-up gas.
The purpose of this utility model is exactly by the improvement to existing pump, but forms a kind of both make-up gas, dual-purpose pump able to drawing air again.
The purpose of this utility model realizes in the following way, the dual-purpose pump of can bleeding comprises gas outlet valve, cylinder block, cylinder piston and tracheae, it is characterized in that increasing a reverse Aspirating valves, on the same base that is fixed on cylinder block with gas outlet valve, and be communicated with cylinder block, it is the two way sealed piston that cylinder piston in the cylinder block changes single acting piston, tracheae can be according to the different purposes of inflating or bleeding, be connected with gas outlet valve or Aspirating valves by the tracheae exclusive clamps, when using as air-breathing purposes, the other end of tracheae is fixed a vacuum switch by the tracheae exclusive clamps.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a vacuum switch structure schematic representation of the present utility model.
Embodiment below in conjunction with accompanying drawing provides is described in detail the utility model.As shown in Figure 1, the dual-purpose pump of can bleeding comprises outgassing nonreturn valve 1, cylinder block 2, cylinder piston 3, breather cheek valve 4, tracheae exclusive clamps 5, tracheae 6 and vacuum switch 7, breather cheek valve 4 is reverse with outgassing nonreturn valve 1, is arranged on the base of cylinder block 2, and be communicated with cylinder block 2, cylinder piston 3 is the two way sealed piston, can easy on and off activity in cylinder block 2 by piston rod, and tracheae 6 is by tracheae exclusive clamps 5, according to inflating or air-breathing different purposes, be connected with outgassing nonreturn valve 1 or breather cheek valve 4 at any time.The utility model is when using as suction pump, and the other end of tracheae 6 connects a vacuum switch 7 by the tracheae exclusive clamps.As shown in Figure 2, vacuum switch 7 bags regulating handle 7-1 alive, adjusting screw rod 7-2, vaccum case 7-3, top 7-4, rubber sheet gasket 7-5 and gland nut 7-6 when needs are bled, make vacuum switch be connected with the cavity that need bleed by gland nut 7-6, wait to bleed finish after, rotate regulating handle 7-1, drive adjusting screw rod 7-2, the vacuum cavity that top 7-4 sealing has been bled.
