Secure with the thrust bearing screws (15).

그리고 랙크(5)의 상부에는 피스톤(3)을 장착하고 외부에는 실린다 튜브(13)를 장착한 후 실린다 튜브(13)의 상부 끝단에는 엔드 플랜지(4)로서 덮고, 타이 로드(14)와 너트(25)로서 죄임한 후 상부 스톱 세팅 나사(30)는 엔드 플렌지(4)의 중심에 심고, 하부 스톱 세팅 나사(30)는 하우징(1)의 하부 중심에 심는다.Then, the piston 3 is mounted on the upper part of the rack 5 and is mounted on the outside. The tube 13 is mounted on the outside, and the upper end of the tube 13 is covered with an end flange 4, the tie rod 14 and the nut. After tightening as 25 the upper stop setting screw 30 is planted in the center of the end flange 4 and the lower stop setting screw 30 is planted in the lower center of the housing 1.

이와 같이 된 본 고안은 엑츄에이타의 하우징(1)내부에 랙크(5)와 랙크기어(2) 내장하고 랙크(5)의 상단에는 실린다 튜브(13)를 형성하여 그 내부에는 피스톤(3)을 취부하여 콤프레샤의 공기압을 실린다 튜브(13) 상·하부에 주입하여 피스톤(3)이 상·하로 작동하면 밸브가 자동으로 개폐토록 한 것이다.The present invention has a rack (5) and rack gear (2) in the housing (1) of the actuator, and the tube (13) formed on the upper end of the rack (5) to form a piston (3) inside the When the piston (3) is operated up and down by injecting the upper and lower parts of the tube (13), the valve is automatically opened and closed.

이와 같이 된 본 고안은 상·하수도, 공업용수, 정수장, 댐등의 관로 및 관로의 유입 및 유출축에 설치되는 각종 대형밸브 및 수문의 개폐장치인 랙크기어 내장 더블(DOUBLE) 공기압식 엑츄에이타에 관한 것으로서, 종래에는 밸브를 개폐하기 위하여 밸브의 몸통에 웜 감속기 및 전동 엑츄에이타를 부착하여 사용하므로 인해 회전효율이 급격하게 저하되어 많은 토오크(TORQUE)가 발생하고, 개폐속도가 느려 밸브의 디스크가 스무스(SMOOTH)하게 작동하지 않아 절도있는 동작이 되지 않음은 물론 많은 힘과 동력이 소요되어 유지관리에 상당한 애로가 있었으나 상기와 같은 장치로 밸브를 개폐하면 종래의 밸브의 저효율, 저속도 등을 방지하여 준다.In this way, the present invention relates to a rack-mounted double-acting pneumatic actuator, which is an opening / closing device for various large valves and gates installed on inflow and outflow shafts of water pipes, industrial water, water purification plants, dams, and the like. Conventionally, in order to open and close a valve, a worm reducer and an electric actuator are attached to the body of the valve so that the rotation efficiency is drastically reduced, resulting in a large amount of torque, and the opening and closing speed of the valve is smooth. (SMOOTH) It was not operated so steeply as well as it took a lot of power and power, and there was considerable difficulty in maintenance, but opening and closing the valve with the above device prevents the low efficiency and low speed of the conventional valve. .

이와 같은 본 고안은 일반장소, 방폭장소에서 약한 공기압으로 더블 엑팅(DOUBLE ACTING)의 힘을 발휘하여 대형의 밸브를 스무스하게 작동하게 하고 전기선이 없이 방폭지역에 사용하면 커다란 효과가 있다.Such a design has a great effect when the large valve is operated smoothly by using a double acting force with a weak air pressure in a general place and an explosion-proof place, and there is no electric wire.
