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 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.

Apparatus for forming a fluidic seal such as in a clean service relief valve. In accordance with some embodiments, a ring-shaped sealing member has an annular main body portion with an innermost surface at an innermost diameter, an outermost surface at an outermost diameter and opposing top and bottom flat surfaces which respectively extend between the innermost surface and the outermost surface. An annular first projection extends away from the top flat surface in a first direction, and an annular second projection extends away from the bottom flat surf...

1. An apparatus comprising a ring-shaped sealing member comprising an annular main body portion with an innermost surface at an innermost diameter, an outermost surface at an outermost diameter, opposing top and bottom flat surfaces which respectively extend between the innermost surface and the outermost surface, an annular first projection which extends away from the top flat surface in a first direction, and an annular second projection which extends away from the bottom flat surface in an opposing second direction, the innermost surface of the sealing member forming a cylindrically shaped sealing surface, the apparatus further comprising a movable valve member having a cylindrically shaped wall that contactingly engages the innermost surface to establish a fluidic seal, the apparatus further comprising first and second housing components of a valve assembly between which the sealing member is compressingly disposed to form a fluidic seal, the first housing component having a first base surface which contactingly engages the top flat surface of the sealing member and a first annular groove into which the annular first projection contactingly extends, the second housing component having a second base surface which contactingly engages the bottom flat surface of the sealing member and a second annular groove into which the annular second projection contactingly extends, the apparatus further comprising a main body formed from the first and second housing components and a moveable piston arranged for axial movement within the main body, the moveable piston having an outer cylindrical surface contactingly engaging the innermost surface of the sealing member, the apparatus further comprising a clamp ring which engages flanges on the first and second housing components on opposing sides of the sealing member to apply a compressive force upon the sealing member and establish the fluidic seal. 2. The apparatus of claim 1, in which the annular main body portion has a rectilinear cross-sectional shape. 3. The apparatus of claim 2, in which the first and second projections each have a circular cross-sectional shape. 4. The apparatus of claim 1, in which the first projection is axially aligned with the second projection. 5. The apparatus of claim 1, in which the first projection is axially offset with respect to the second projection. 6. The apparatus of claim 1, in which the first and second projections are nominally centered between the innermost surface and the outermost surface so that a first distance from a centerpoint of each of the first and second projections to the innermost surface is nominally equal to a second distance from the centerpoint of each of the first and second projections to the outermost surface. 7. An apparatus comprising: a first housing component;a second housing component; andan annular ring-shaped sealing member comprising an annular main body portion with an innermost surface, an outermost surface, opposing top and bottom flat surfaces, an annular first projection which extends from the top flat surface, and an annular second projection which extends from the bottom flat surface, the sealing member compressingly engaged between an upper annular extent of the first housing component and a lower annular extent of the second housing component to form a sealed housing;a moveable piston arranged to axially move within the first and second housing components, the piston comprising a cylindrical outer surface which sealingly engages the innermost surface of the sealing member to form a fluidic seal, the apparatus characterized as a clean service pressure relief valve comprising an inlet port and an outlet port, the cylindrical outer surface of the piston sealing engaging the innermost surface of the sealing member to form the fluidic seal between the inlet port and the outlet port to provide a normally closed valve; anda mechanically collapsible member connected to the moveable piston, wherein responsive to a pressure of a pressurized fluid proximate the inlet port reaching a predetermined threshold, the piston moves axially away from the inlet port and mechanically collapses the mechanically collapsible member to transition the valve to an open position that fluidically couples the inlet port to the outlet port, wherein the cylindrical outer surface slides along and then disengages from the innermost surface of the sealing member during transitioning to the open position. 8. The apparatus of claim 7, further comprising a clamp ring which surrounds the sealing member to compressingly engage the first and second housing components to secure the second housing component to the first housing component and to compress the sealing member therebetween. 9. The apparatus of claim 8, further comprising a threaded fastener which engages a corresponding set of threads of the clamp ring. 10. The apparatus of claim 7, wherein the annular ring-shaped sealing member is a first sealing member, and wherein the apparatus further comprises: a third housing component axially aligned with the first and second housing components; anda second annular ring-shaped sealing member comprising an annular main body portion with an innermost surface, an outermost surface, opposing top and bottom flat surfaces, an annular first projection which extends from the top flat surface, and an annular second projection which extends from the bottom flat surface, the second sealing member compressingly engaged between an upper annular extent of the second housing component and a lower annular extent of the third housing component to form the sealed housing. 11. A clean service valve, comprising: a housing defining an inlet port, an outlet port and an interior fluidic passage therebetween, the housing comprising: a first housing component; anda second housing component;an annular ring-shaped sealing member comprising an annular main body portion with an innermost surface, an outermost surface, opposing top and bottom flat surfaces, an annular first projection which extends from the top flat surface, and an annular second projection which extends from the bottom flat surface, the sealing member compressingly engaged between an upper annular extent of the first housing component and a lower annular extent of the second housing component;a valve assembly disposed within the housing comprising a piston moveable between a normally closed position and a bypass open position, the piston having a cylindrical outer surface which sealingly engages the innermost surface of the sealing member to form a fluidic seal in the normally closed position; anda mechanically collapsible member connected to the moveable piston, wherein responsive to a pressure of a pressurized fluid proximate the inlet port reaching a predetermined threshold, the piston moves axially away from the inlet port and mechanically collapses the mechanically collapsible member to transition the valve to the open position, wherein the cylindrical outer surface slides along and then disengages from the innermost surface of the sealing member during transitioning to the open position. 12. The apparatus of claim 11, further comprising: a clamp ring assembly comprising first and second hinged clamp segments which surround and contactingly engage corresponding flanges on the first and second housing components and the outermost surface of the sealing member, and a fastener which threadingly engages the respective first and second housing components to apply a compressive force upon the sealing member to establish the fluidic seal.
