Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for increasing air pressure and a low-pressure and high-pressure air compressor, and it is possible to stably produce high-pressure compressed air from a low-pressure air compressor. The purpose is to pursue.

[0002]

2. Description of the Related Art As a conventional technique, when using low-pressure compressed air, an air compressor that produces low-pressure compressed air is used. When using high-pressure compressed air, high-pressure compressed air is produced. High pressure air compressor was used. That is,
Two air compressors were used.

On the other hand, techniques for producing high-pressure compressed air using an air compressor that produces low-pressure compressed air include:
The use of booster valves has been known for some time, but has had problems.

[0004]

However, the conventional methods for increasing the pressure of air and the low-pressure and high-pressure air compressors have the following problems. First, when you want to use both low-pressure and high-pressure compressed air, use a low-pressure air compressor for low pressure, use a high-pressure air compressor for high pressure, and connect two air compressors. I was using. In this case, the high-pressure air compressor is used less frequently in spite of the high purchase price, and there are many problems in terms of the operation rate.

[0005] Second, a technique for producing high-pressure compressed air using a pressure-intensifying valve has been conventionally known, but it has pulsation and is unstable. Third, when the high pressure compressed air is produced and used by the booster valve and the low pressure compressed air is also used at the same time, two air tanks for high pressure and low pressure are required. Management was troublesome, and it was difficult in terms of cost and securing an installation place.

Fourth, the use of compressed air produced by an air compressor in pneumatic equipment requires a large number of joints and is cumbersome to connect. Fifth, when connecting piping to use pneumatic equipment, low-pressure and high-pressure compressed air are used, so high-pressure compressed air is incorrectly fed to low-pressure pneumatic equipment. In some cases, low-pressure pneumatic equipment could be damaged.

Sixth, the use of a one-touch joint makes it easy to connect the pipes. When a one-touch joint is used, the pressure builds up particularly when high-pressure compressed air passes through the joint, making it difficult to attach and detach the one-touch joint. There was a case. Seventh, this air compressor uses various high-pressure hoses and low-pressure hoses, but it has been difficult to strike these long hoses. An object of the present invention is to solve such a problem.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for increasing air pressure and a low-pressure and high-pressure air compressor according to the present invention will be described in detail with reference to the drawings.

In general, the air compressor 40 is shown in FIGS.
As shown in FIGS. 3 and 4 showing the first to fourth examples of the air compressor according to the present invention, the air compressor body 4
5 and an electric motor 46, and sucks air from an air intake 47 provided in the air compressor main body 45.
In the present invention, the air compressor 40 includes the compressed air tank 10.
A, when it is installed on the upper part of the air compressor 21 and the air compressor 4
There is a case where the air compressor A 40A is constituted by the zero and the base 48 and is separately provided.

Further, in the present invention, the air compressor 40
Is characterized in that the compressed air created by the above is made into compressed air of higher pressure by the pressure increasing valve 61.
In this case, it is a feature of the present invention to generate pulsation-free compressed air and to supply the compressed air to both the low-pressure and high-pressure pneumatic devices 53 and 58. The low-pressure compressed air is compressed air of 10 kgf / cm ² or less, and the high-pressure compressed air is 2 to 4 times the low-pressure compressed air.

Here, the structure and operation of the pressure increasing valve 61 will be described.
First, the structure is as shown in FIG.
A booster valve body 62 composed of a chamber 62A, a central portion 62B and a chamber 62C, a piston 63A and a piston rod 63B.
And a piston 63 comprising a piston filter 63C and a governor 6
4, a switching valve 65, and four sets of check valves 66A, 6
6B, 66C and 66D. On the other hand, a piston rod 63B slides in the middle of a central portion 62B of the pressure-intensifying valve main body 62, and a governor 64 and a switching valve 65
And four sets of check valves 66A, 66B, 66C, 66D
And other air piping.

The piston 63 has a piston 63A.
The piston rod 63C is arranged to operate the full stroke of the chamber 62C while the piston operates the full stroke of the chamber 62A. That is, the stroke of the chamber A 62A and the stroke of the chamber B 62C are set to be the same.

Further, when the piston 63A operates inside the chamber 62A, the piston 63A moves the chamber 62A to the drive chamber 62AA on the opposite side of the piston rod 63B and the pressure increasing chamber 62AB on the piston rod 63B side. When the piston filter 63C operates the chamber 62C, the piston filter 63C
, The chamber 62C is connected to the drive chamber 62CB on the opposite side of the piston rod 63B and the pressure increasing chamber 6 on the piston rod 63B side.
2CA.

Next, the operation is as follows.
The check valves 66A and 66B communicate with the pressure-intensifying chamber A 62AB and the pressure-increasing chamber B 62CA. On the other hand, air is supplied to the drive chamber 62CB via the governor 64 and the switching valve 65. Then, the air pressure in the driving chamber B 62CB and the pressure in the pressure increasing chamber A 62AB acts on the piston 63 to increase the pressure in the air in the pressure increasing chamber B 62CA. Then, the air whose pressure is increased by operating the piston 63 is sent from the check valve 66D to OUT (secondary side).

At the end of the stroke, the switching valve 6
5 switches to a state in which the driving chamber B 62CB exhausts and the driving chamber A 62AA supplies. Then, the piston 63 reverses, and the pressure in the pressure-intensifying chamber B 62CA and the pressure in the driving chamber A 62AA increases the pressure in the air in the pressure-increasing chamber A 62AB.
(Secondary side). In this manner, while repeating the above, air at a pressure higher than IN is continuously supplied to OUT.

In this case, the secondary pressure can be arbitrarily set by operating the handle of the governor 64 mechanism that feeds back the secondary pressure. The structure of the booster valve 61 is such that the cross-sectional area of the chamber A 62A is different from the cross-sectional area of the chamber B 62C, and the drive chamber A 62AA, the pressure booster chamber 62A, the pressure booster chamber 62CA, and the drive chamber 62CB are different. By exchanging positions, structures other than those described are possible.
