연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

1. A method of controlling the flow of a fluid in a pipe system comprising: controlling a sleeve valve in the pipe system, the sleeve valve including a valve body having an inner surface and an outer surface, the inner surface and the outer surface defining an inlet, an outlet, and a body cavity between the inlet and the outlet;a sleeve disposed at least partially within the body cavity, the sleeve including at least one opening fluidly connecting the inlet to the outlet;a gate proximate to the sleeve, the gate including a front stop and a back stop; anda drive assembly including a pair of drive lines, each drive line including a drive shaft, a first drive line of the pair of drive lines including a sync cam on the drive shaft of the first drive line, the sync cam of first drive line movably positioned between the front stop and the back stop, a first gap defined between the front stop and the sync cam, a second gap defined between the back stop and the sync cam;moving the sync cam to a front stop position, wherein the front stop position reduces the first gap; andmoving the gate to uncover the at least one opening to allow fluid to flow from the inlet to the outlet. 2. The method of claim 1, further comprising partially obstructing the at least one opening with the gate to partially reduce a flow rate of fluid from the inlet to the outlet. 3. The method of claim 1, wherein each drive line of the pair of drive lines is connected to an actuator motor, the method further comprising turning the drive shaft of each drive line at equal speeds. 4. The method of claim 1, wherein: the front stop is a first front stop, the back stop is a first back stop, and the sync cam is a first sync cam; andthe sleeve valve further includes a second drive line of the pair of drive lines, the second drive line including a second sync cam, the second sync cam movably positioned on the drive shaft of the second drive line and between a second back stop and a second front stop, a third gap defined between the second front stop and the second sync cam, and a fourth gap defined between the second back stop and the second sync cam. 5. The method of claim 4, wherein the front stop position is a first front stop position, the method further comprising moving the second sync cam to a second front stop position, wherein the second front stop position reduces the third gap. 6. The method of claim 5, wherein the first sync cam contacts the first front stop at the first front stop position. 7. The method of claim 6, wherein the second sync cam contacts the second front stop at the second front stop position simultaneously with the first sync cam contacting the first front stop at the first front stop position. 8. The method of claim 6, further comprising syncing the first sync cam and the second sync cam if the second sync cam does not contact the second front stop at the second front stop position simultaneously with the first sync cam contacting the first front stop, wherein syncing causes the first sync cam to contact the first front stop at the first front stop position simultaneously with the second sync cam contacting the second front stop at the second front stop position. 9. The method of claim 8, wherein the second sync cam further comprises at least one front direction load balancing screw and wherein syncing the first sync cam and the second sync cam comprises adjusting the at least one front direction load balancing screw to cause the second sync cam to contact the second front stop at the second front stop position simultaneously with the first sync cam contacting the first front stop at the first front stop position. 10. The method of claim 4, further comprising moving the first sync cam to a first back stop position, wherein the first back stop position reduces the second gap; andmoving the gate to cover the at least one opening to reduce fluid from flowing from the inlet to the outlet. 11. The method of claim 10, further comprising moving the second sync cam to a second back stop position, wherein the second back stop position reduces the fourth gap, and wherein the first sync cam contacts the first back stop at the first back stop position. 12. A method of controlling the flow of a fluid in a pipe system comprising: controlling a sleeve valve in the pipe system, the sleeve valve including a valve body having an inner surface and an outer surface, the inner surface and the outer surface defining an inlet, an outlet, and a body cavity betweenthe inlet and the outlet;a sleeve disposed at least partially within the body cavity, the sleeve including at least one opening fluidly connecting the inlet to the outlet;a gate proximate to the sleeve, the gate including a front stop and a back stop; anda drive assembly including a pair of drive lines, each drive line including a drive shaft, a first drive line of the pair of drive lines including a sync cam on the drive shaft of the first drive line, the sync cam of first drive line movably positioned between the front stop and the back stop, a first gap defined between the front stop and the sync cam, a second gap defined between the back stop and the sync cam;moving the sync cam to a back stop position, wherein the back stop position reduces the second gap; andmoving the gate to cover at least one opening to reduce fluid from flowing from the inlet to the outlet. 13. The method of claim 12, wherein the at least one opening comprises a plurality of openings, the method further comprising uncovering some of the plurality of openings with the gate to partially increase a flow rate of fluid from the inlet to the outlet. 14. The method of claim 12, wherein each drive line of the pair of drive lines is connected to an actuator motor, the method further comprising turning the drive shaft of each drive line at equal speeds. 15. The method of claim 12, wherein: the front stop is a first front stop, the back stop is a first back stop, and the sync cam is a first sync cam; andthe sleeve valve further includes a second drive line of the pair of drive lines, the second drive line including a second sync cam, the second sync cam movably positioned on the drive shaft of the second drive line and between a second back stop and a second front stop, a third gap defined between the second front stop and the second sync cam, and a fourth gap defined between the second back stop and the second sync cam. 16. The method of claim 15, wherein the back stop position is a first back stop position, the method further comprising moving the second sync cam to a second back stop position, wherein the second back stop position reduces the fourth gap. 17. The method of claim 16, wherein the first sync cam contacts the first back stop at the first back stop position. 18. The method of claim 17, wherein the second sync cam contacts the second back stop at the second back stop position simultaneously with the first sync cam contacting the first back stop at the first back stop position. 19. The method of claim 17, further comprising syncing the first sync cam and the second sync cam if the second sync cam does not contact the second back stop at the second back stop position simultaneously with the first sync cam contacting the first back stop, wherein syncing causes the first sync cam to contact the first back stop at the first back stop position simultaneously with the second sync cam contacting the second back stop at the second back stop position. 20. The method of claim 19, wherein the second back stop further comprises at least one backward direction load balancing screw and wherein syncing the first sync cam and the second sync cam comprises adjusting the at least one backward direction load balancing screw to contact the second sync cam at the second back stop position simultaneously with the first sync cam contacting the first back stop at the first back stop position.
