Regulation system for water level of sump

본 발명은 집수정 수위 조절장치를 개시한다. 본 발명은 기초 시공기준면에 설치되어 지하수를 수집하는 집수관의 출구에 동축으로 연결되는 배수관부와, 이 배수관부에 수직으로 교차하는 실린더부를 갖는 밸브바디; 이 밸브바디의 실린더부 안에서 승강하고, 몸체의 하부에 배수관부와 선택적으로 연통하는 유로구멍을 가지며, 몸체의 상부 주면에 집수관 쪽으로 개구된 압력홈을 갖는 피스톤; 유로구멍이 배수관부에서 벗어나도록 피스톤을 하방으로 탄성바이어스 시키는 탄성수단;을 포함한다. 또한 집수관으로 유입된 지하수의 압력에 따라 피스톤이 승강할 때 회전이 발생되지 않도록 안내하는 안내수단을 더 포함할 수 있다. 본 발명은 집수관에 유입된 지하수의 압력이 설정압력을 초과하는 경우에만 지하수를 집수정으로 배수할 수 있으면서도 구성이 간단하여 제작과 시공이 용이함은 물론이고 원가절감에도 기여할 수 있다.

Lng storage tank level transmitter inspection window unit and lng storage system including the same

본 발명의 일 실시예에 따른 LNG 저장탱크 액위전송기용 점검창 유닛은 액위전송기에 설치되어 액위전송기의 센서의 위치를 육안으로 확인이 가능하다는 장점이 있습니다. 또한, 본 발명의 다른 실시예에 따른 LNG 저장 시스템의 LNG 저장탱크 액위전송기는 LNG 저장탱크에 설치된 차단밸브에 점검창 유닛을 통해 연결되는데, 액위전송기 고장시 LNG 점검창 유닛의 기체유입관으로 질소를 주입하여 초저온 상태인 센서의 웜업시간을 1시간에서 약 10분으로 단축시킬 수 있습니다. 반대로 수리한 액위전송기를 설치할 경우 점검창 유닛의 기체유입관을 통해 질소를 주입하여 센서에 부착된 수분 등을 제거하여 수분 등에 의해 센서가 이상동작하는 문제를 방지할 수 있습니다.

Nonlinear control of liquid level

NONLINEAR CONTROL OF LIQUID LEVEL Abstract of the Disclosure In a process in which liquid flows to a vessel and is then withdrawn from the vessel, method and apparatus is provided for implementing nonlinear liquid level control by providing a variable set point to a conventional level controller. The variable set point is a nonlinear function of the actual liquid level in the vessel. The variable set point enables the vessel to absorb disturbances in the flow rate of the liquid flowing to the vessel while the actual liquid level in the vessel remains between a desired high and low limit thus providing a smooth flow of liquid from the vessel.
