제 1 도는 본 발명의 구성도를 나타낸 것으로서 바틀(Bottle)(1)(1')(1")과 압력레귤레이터(3)(3')(3"), 체크밸브(4)(4')(4"), 파워미터(5)(5')(5")를 직렬연결하되 바틀(1)(1')(1")과 압력레귤레이터(3)(3')(3") 사이에 가스가 흘러가는 과정에서 일정한 기압을 유지할 수 있도록 압력스위치(2)(2')(2")를 연결하였다. 그리고 상기 파워미터(5)(5')(5")의 각 출구를 결합하여 하나의 출구로 한 후 이 출구를 "온", "오프" 스위치 역할을 하는 2웨이 솔레노이드밸브(2Way Solenoid Valve)(6)와 일정한 기압으로 유지하기 위한 바틀(9)과 연결하되, 상기 2웨이 솔레노이드밸브(6)와 바틀(9) 사이에는 가스기압의 양을 자동으로 적고 많은 양을 조절하여 주는 압력스위치(7)(8)를 연결하였다. 그리고 바틀(9)은 캐피티(Cavity) 내의 압력상태를 유지하면서 필요한 양만큼 가스를 조절하여 흘러 보낼 수 있도록 압력게이지(10)가 연결된 상태로 압력레귤레이터(11), 파워미터(12)와, 니이들밸브조절 모터(13)를 연결하고, 이 니이들밸브조절모터(13)의 출구에"온", "오프" 스위치 역할만 하는 2웨이 솔레노이드밸브(14)와 연결하였다.1 shows a schematic diagram of the present invention, in which a bottle 1, 1 ', 1 ", a pressure regulator 3, 3', 3", and a check valve 4, 4 'are shown. (4 "), connect the power meter (5) (5 ') (5") in series but between the bottle (1) (1') (1 ") and the pressure regulator (3) (3 ') (3") Pressure switches (2), 2 ', and 2 "are connected to maintain a constant air pressure during the flow of gas. And each outlet of the power meter (5), 5', 5" is coupled The outlet is connected to a two-way solenoid valve 6 serving as an "on" and an "off" switch and a bottle 9 for maintaining a constant air pressure. Between the solenoid valve (6) and the bottle (9) was connected to the pressure switch (7) (8) to automatically reduce the amount of gas pressure and to adjust a large amount. And the bottle 9 is the pressure regulator 11, the power meter 12, and the pressure gauge 10 is connected to the flow of the gas to adjust the required amount while maintaining the pressure state in the cavity (Cavity), The needle valve regulating motor 13 was connected and connected to the outlet of this needle valve regulating motor 13 with a two-way solenoid valve 14 serving only as an "on" and "off" switch.

그리고 상기 압력게이지(10)와 압력레귤레이터(11) 사이에는 빨리 개피티내에 압력상태를 유지하기 위하여 니이들밸브(16)를 연결하되, 이 니이들밸브(16)의 출구에는 2웨이 솔레노이드밸브(17)를 연결하였다. 또한 니이들밸브(16)의 입구측으론 대기압으로 갈때 사용하는 2웨이 솔레노이드밸브(15)를 연결하여 가스를 혼합할 수 있도록 구성된 것이다.In addition, a needle valve 16 is connected between the pressure gauge 10 and the pressure regulator 11 so as to quickly maintain a pressure state in the pit fit, and the outlet of the needle valve 16 is a 2-way solenoid valve ( 17). In addition, the inlet side of the needle valve 16 is configured to connect the two-way solenoid valve 15 used when going to atmospheric pressure to mix the gas.

이와같이 구성된 본 발명은 바틀(1)(1')(1")의 가스를 압력스위치(2)(2')(2")에서 어느 일정한 기압을 유지하여 압력레귤레이터(3)(3')(3")로 흘러보내준다. 이때 압력레귤레이터(3)(3')(3")의 입구측에서는 바틀(1)(1')(1")의 압력과 같도록 유지시켜주는 것이 바람직하다.According to the present invention configured as described above, the gas of the bottle 1, 1 ', 1 "is maintained at a certain air pressure at the pressure switch 2, 2', 2", and the pressure regulator 3, 3 '( 3 "). At the inlet side of the pressure regulator 3, 3 ', 3", it is desirable to maintain the same pressure of the bottle 1, 1', 1 ".

그리고 상기 압력레귤레이터(3)(3')(3")의 출구에서 항상 일정한 기압이 유지되는 상태로 체크밸브(4)(4')(4")를 통과하여 가스의 양을 조절하는 파워미터(5)(5')(5")로 필요한 양만큼 조절하면서 보내주게 된다. 그리고 파워미터(5)(5')(5")에서는 가스기압의 양을 솔레노이드밸브 전압에 의거하여 적고, 많은 양을 압력스위치(7)(8)에서 조절하여 바틀(9)로 흘러보내게 된다.And a power meter that adjusts the amount of gas through the check valves 4, 4 ', 4 "while maintaining a constant air pressure at the outlet of the pressure regulator 3, 3', 3". (5) (5 ') (5 ") to adjust the required amount. And in power meter (5) (5') (5"), the gas pressure is small based on the solenoid valve voltage. The amount is controlled by the pressure switch (7) (8) to flow to the bottle (9).

이때 상기 바틀(9)로 흘러온 가스는 솔레노이드 전압에 의하여 일정한 기압을 유지하면서 Low, High 양이 조절된다.At this time, the gas flowing into the bottle 9 is controlled to a low, high amount while maintaining a constant air pressure by the solenoid voltage.

그리고 상기 바틀(9)의 출구에서는 압력레귤레이터(11), 2웨이 솔레노이드밸브(15), 니이들밸브(16)로 흘러보내되 일정한 가스기압만 자동으로 조절하여 흘려보낼 때에는 바틀(9)에서 압력레귤레이터(11)와 파워미터(12)를 통과하고 니이들밸브조절모터(13)를 통과하여 자동조절되어 "온", "오프" 스위치인 2웨이 솔레노이드밸브(14)에 의하여 조절되는 것이다. 이때 2웨이 솔레노이드밸브(14)는 "온", "오프" 스위치 역할만 한다. 그리고 빨리 캐피티내의 압력상태를 유지할 때에는 바틀(9)에서 필요한 양의 가스가 조절되면 가스를 니이들밸브(16)로 보내 자동조절한 후 2웨이 솔레노이드밸브(17)에 의해 자동조절하여 흘러보내고, 대기압으로 갈때에는 바틀(9)에서 2웨이 솔레노이드밸브(15)를 통하여 곧바로 통과하게 조절하는 것이다.At the outlet of the bottle 9, the pressure regulator 11, the two-way solenoid valve 15, the needle valve 16 flows, but only the constant gas pressure is automatically adjusted and flowed through the bottle 9 when flowing. It passes through the regulator 11 and the power meter 12 and passes through the needle valve control motor 13 and is automatically adjusted by the two-way solenoid valve 14 which is an "on" and "off" switch. At this time, the 2-way solenoid valve 14 serves only as an "on" and "off" switch. In order to maintain the pressure in the cavity quickly, when the required amount of gas is adjusted in the bottle 9, the gas is sent to the needle valve 16 for automatic adjustment, and then automatically adjusted by the two-way solenoid valve 17 for flow. When going to atmospheric pressure, the bottle 9 is adjusted to pass straight through the two-way solenoid valve 15.

이상 설명한 바와같이 본 발명은 바틀에서 압력스위치의 작동에 따라 일정한 기압을 유지하여 압력레귤레이터, 체크밸브, 파워미터를 통과하여 "온", "오프" 스위치 역할을 하는 2웨이 솔레노이드밸브로 각각의 파워미터에서 모아져 통과한 후 가스기압량을 솔레노이드밸브 전압으로 적고 많은 양을 자동조절하여 일정한 기압을 유지하게 하여 바틀로 흘려 보내준다.As described above, the present invention maintains a constant air pressure according to the operation of the pressure switch in the bottle, and passes through the pressure regulator, the check valve, and the power meter to act as an "on" and "off" switch. After collecting and passing through the meter, the gas pressure is reduced by the solenoid valve voltage, and a large amount is automatically adjusted to maintain a constant air pressure and flow it into the bottle.

이와같이 바틀에 모아진 혼합가스는 니이들밸브조절모터에서 가스량을 조절하여 통과시키고 가스량을 빨리 통과시키고자 할 때에는 바틀에서 니이들밸브로 통과하며, 대기압으로 통과시킬 때에는 바틀에서 곧바로 2웨이 솔레노이드밸브를 통하여 통과시키므로서 가스의 양을 자동으로 조절하기 때문에 가스의 소비량을 현저히 줄일 수 있을 뿐아니라, 이산화탄소 레이저의 방전 및 파워를 안정시킬 수 있는 효과가 있다.In this way, the mixed gas collected in the bottle passes through the needle valve regulating motor to regulate the gas volume and passes from the bottle to the needle valve to pass the gas volume quickly. Since the amount of gas is automatically adjusted by passing, the consumption of the gas can be significantly reduced, and the discharge and power of the carbon dioxide laser can be stabilized.
