Abstract

PURPOSE:To provide a piping system for manufacturing and using compressed air, and prevent a plurality of pipes from being connected by mistake. CONSTITUTION:Compressed air manufactured by a compressor 1 for manufacturing a compressed air of middle pressure (e.g. 10-30kg/cm<2>) passes through a currently generally employed female fluid coupling A combined to a decompressing valve (A) 4 which is limited only to e.g. 10kg/cm<2> at the maximum in its pressure rise, and then, through a hose (A) 6, fed into a pneumatic driving machine (A) 2 equipped with a currently generally employed male fluid coupling (A) 10. Whereas, compressed air that is an initial pressure or somewhat decompressed by a compressing valve (B) 5 attached to the compressor 1 passes through a female fluid coupling (B) 9 having no compatibility with a current fluid coupling combined to a decompressing valve (B) 5, and then, through a hose (B) 7, fed into a small and light-weight pneumatic driving machine (B) 3 equipped with a male fluid coupling (B) 11 having no compatibility being the same as the foregoing.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system including a compressor, which is used as a power source for a nailer, etc., using compressed air as a power source, and a hose.

0002

2. Description of the Related Art A conventional system of a compressor, an air-driven driving machine, and a hose will be described, for example, in the case where two driving machines are used instead of one compressor.

The compressor is equipped with two or more mutually compatible female fluid couplings, the two hoses are each equipped with interchangeable female and male fluid couplings, and ,
Each air intake of the driving machine was equipped with a compatible female fluid coupling. Therefore, since the fluid couplings are compatible, the above-mentioned hose and driving machine can be interchanged and connected.

[Problems to be Solved by the Invention] In conventional systems, because the fluid couplings are compatible, for example, the pressure of the compressed air is set lower than the internal pressure in the tank by a pressure reducing valve installed in the compressor. There have been cases in which a hose that supplies a pressure approximately close to the internal pressure of the tank is mistakenly connected to a compressor or an air-driven driving machine. Therefore, for example, if the hose of a driving machine used with reduced air pressure is connected to a fluid coupling that supplies a pressure close to the internal pressure of the tank, air may leak from the sealing surface of the driving machine. There was a problem in that the pressure vessel of the driving machine was at risk of bursting.

[0005] Furthermore, if the connection is reversed to the above, there is a problem of insufficient implantation.

An object of the present invention is to solve the above-mentioned two problems.

[0007]

The above object is achieved by making the fluid couplings attached to the compressor, hose, and driving machine incompatible with each other, thereby preventing erroneous connections.

[0008]

[Operation] In the system achieved with at least two types of incompatible fluid couplings as described above, low-pressure compressed air is supplied to the low-pressure driving machine, and medium-pressure compressed air is supplied to the medium-pressure driving machine.

[0009]

[Embodiment] An embodiment of a system of a pneumatic driving machine and a compressor according to the present invention will be described with reference to FIG. Compressor 1 has medium pressure (for example, about 10 to 30 kg/cm2)
One of the pressure reducing valves (A) 4 attached to the compressor 1 can raise the pressure up to a low pressure (for example, about 7 to 10 k
g/cm2), and the other pressure reducing valve (B) 5 can take out the maximum pressure up to medium pressure, and the former is equipped with a commonly used female fluid coupling (A) 8. A new female fluid coupling (B) 9, which is incompatible with the female fluid coupling (A) 8, is attached to the latter. The hose that supplies the compressed air generated by the compressor to the pneumatic driving machine is
A generally used female fluid coupling (A) 8, a hose (A) with a similarly commonly used male fluid coupling (A) 10 attached to both ends, a female type, a male type There is a hose (B) in which a female fluid coupling (B) 9 and a male fluid coupling (B) 11, both of which are incompatible with the aforementioned fluid couplings, are attached to both ends. The driving machine uses a commonly used male fluid coupling (
A) Pneumatic driving machine with 10 attached to the air intake (
There is a male fluid coupling (B) 11 that is incompatible with A) 2 and the male fluid coupling (A) 10 described above. By connecting each of the above-mentioned devices as shown in the arrows shown in FIG.
It is supplied to the pneumatic driving machine (A) 2 and the pneumatic driving machine (B) 3 via the hose (B) 7, and nails etc. can be driven by the respective driving machines. The air pressure supplied to the pneumatic driving machine (B) 3 is higher than the air pressure supplied to the pneumatic driving machine (A) 2, so if nails of the same size are driven, the former driving machine will It can be made smaller and lighter than the latter.

A modified embodiment is shown in FIG. 2 and will be described. Medium-pressure (for example, about 10 to 30 kg/cm 2 ) compressed air generated by the compressor (C) 14 is supplied to the air dunk 16 via a hose 15 . The air tank 16 has a pressure reducing valve (A) 4 attached to the compressor 1 shown in FIG.
