Abstract
The utility model discloses a pump with the steel ball for the contra-stop, relating to the improvement of the civil pump. A steel ball which can be used as the contra-stop valve is arranged in an air-out nozzle. Thus, the air-out pressure of the common pump can reach about 1.5Mpa, so the utility model improves the efficiency of the common pump.
Description
The utility model relates to the improvement of civilian pump outlet nozzle.
Existing pump kind is more, generally can be divided into No. 1, No. 2, No. 3, No. 4 and No. 5 several models.
No. 1 pump is a high-pressure pump, and it is very big to be furnished with check valve, air inflow on the base, and going out atmospheric pressure can reach about 1.0MPa.
No. 2, No. 3, No. 4 pump is general pump, and the socket height is respectively 450～500mm, 400～450mm, 350～400mm.Its barrel dliameter is basic identical to be 25～28mm approximately.All being unworthy of check valve, is respectively 0.8Mpa so go out atmospheric pressure, 0.6Mpa, 0.4Mpa.Utilize between these pump loam cakes, socket and the base to be threaded, easy disassembling, cost is low, and is easy to carry, but maximum deficiency is that atmospheric pressure low.
The purpose of this utility model is under the prerequisite that does not change general pump original basic structure, proposes a kind ofly to go out atmospheric pressure and can reach pump about 1.5Mpa, goes out the low problem of atmospheric pressure thereby overcome general pump.
The utility model purpose is achieved in that
By the pump that handle, push rod, leather cup, loam cake, socket, base, outlet nozzle, sebific duct, duckbilled constitute, it is characterized in that outlet nozzle is equipped with a steel ball check valve.
Outlet nozzle is parts similar with hex head bolt, and the lower end has screw thread to be connected with base, and the upper end is not have the bolt of screw thread to link to each other with sebific duct, and the centre is a vent, is equipped with steel ball in vent, is referred to as check valve.
Check valve is manufactured like this, and the lower end is the little hole of diameter, and the upper end is the big hole of diameter, forms funnel shape in the middle of aperture and the macropore, is equipped with one piece of steel ball on this funnel shaped position, and diameter of the steel ball is bigger than hole diameter, gets final product than big bore dia is little.Atmosphere pressure losses and increase working life in order to reduce, be not provided with energizing spring on the steel ball, but utilize the difference of steel ball deadweight and air pressure to produce that backpressure seals.It is best that outlet nozzle utilizes copper material to make, and diameter of the steel ball is got 2～3mm chromium steel (Bearing Steel) and is advisable.
In order to prevent that steel ball from blowing off, the place is equipped with non-magnetic shim at the outlet nozzle upper outlet, or makes the outlet port be processed into the cross closing in, and integral body is axial arrangement.
In order to increase oppositely contrary sealing property, put into during making behind the steel ball again to steel ball impulse force in addition, utilize the sphere of steel ball itself, make good the coincideing of funnel surface and steel ball sphere, to reach excellent sealing performance (utilizing grinding machine processing certainly better).
The utility model is in the prior art, on the basis that does not change original structure, only is equipped with one piece of steel ball, the double check valve of making on the outlet nozzle vent.As if do not increase cost, do not increase amount of maintenance, can make the atmospheric pressure that goes out that atmospheric pressure surpasses high-pressure pump on the contrary that of general pump, can satisfy the inflation needs of bicycle, wheelbarrow, improve the usefulness of general pump.
Fig. 1 is the utility model structural representation
Fig. 2 is the utility model outlet nozzle structural representation
Below in conjunction with accompanying drawing the utility model is described further, with reference to scheming:
Handle 1, push rod 2, loam cake 3, socket 4, base 5, outlet nozzle 6, non-magnetic shim 7, steel ball 8, outlet nozzle vent 9, outlet nozzle screw thread 10 sebific ducts 11, duckbilled 12.
Other component slightly.
The vent of outlet nozzle is the little down big structure that, and the centre forms funnel shape, at one piece of steel ball of this holding.Air-flow blows afloat steel ball when push rod presses down, and gas circuit is unimpeded, and when carrying on the push rod, steel ball card stops return-air at the funnel place.
Claims (2)
1, a kind of pump that is made of handle, push rod, leather cup, loam cake, socket, base, outlet nozzle, sebific duct, duckbilled is characterized in that the double steel ball check valve of making axial arrangement of outlet nozzle.
2, it is characterized in that by the described pump of claim 1 inlet hole, steel ball, the air outlet hole of the double steel ball check valve of making of outlet nozzle all present axial arrangement.
