摘要：本發明揭示一種備援密封，其用於避免通過一主要機械密封洩漏至外界。該備援密封包含一聚合物啟動環，其為密封啟動的第一線，並且定義正常情況下與該轉軸相隔的一彈性密封唇。洩漏時，此元件下陷抵住該轉軸或轉軸套管，並且形成一初始密封。由於高速蒸氣、兩階段流動或氣體，將在顯著低洩漏流量上啟動此元件。再來，提供一金屬密封/防擠出環，在洩漏期間提供一第二密封。該聚合物環在低壓力差(例如低於10 psid)的洩漏期間提供該初始密封功能，並且一旦該聚合物環密封至該轉軸或轉軸套管，則增加的密封壓力施力讓該聚合物環抵住該金屬密封/防擠出環導致該環變形，如此該金屬環的內徑與該轉軸或轉軸套管接觸，形成一第二密封。密封啟動與溫度無關，而是與實際洩漏流有關。若無蒸氣洩漏或有非常低的蒸汽洩漏，除非液體洩漏流明顯更高，否則不會啟動。

摘要： A downstream ball valve purging inlet directs purging fluid intentionally onto a downstream portion of the valve ball. The Coanda effect attaches some of the fluid to the ball's surface, so that it flows around the ball to an opposite side thereof, thereby purging the downstream valve cavity more efficiently than designs that avoid impacting the ball and depend on mixing to distribute the purging fluid onto the ball. The purging inlet can be downstream of the ball and directed at an acute angle, proximate the ball and directed perpendicular to the outlet axis, or some combination thereof. A central cavity purging drain can be connected with the purging inlet, so that the same fluid purges both the valve interior and the downstream cavity. Embodiments include a plurality of downstream purging inlets, which can have equal purging angles and can be equally spaced about the outlet axes.

摘要： A heat exchanger for heat exchange between a working fluid and a coolant having an inner casing, an outer casing, and an annular space formed therebetween. A tube bundle including at least one tube formed into a helical coil is located within the annular space. End plates are removably secured and sealed to the ends of the outer casing. Bulkhead fittings are mounted in openings of the end plates to seal the tube ends which pass through the end plates. The bulkhead fittings are sized to permit the end plates to be moved off of the bulkhead fittings in a direction away from the helical coil. The tube bundle may also include a separating plate extending longitudinally between the coils of two tubes within the tube bundle creating two separate passages through which coolant may flow. External tubes may be connected at the tube ends, outside of the outer casing and the end plates, such that the working fluid flows in a parallel single-pass flow or a series double-pass flow through the annular space. A method for servicing the heat exchanger includes disconnecting the heat exchanger from a fluid delivery tube and a fluid return tube, removing the end plates off of the bulkhead fittings in a direction away from the helical coil, removing the inner and outer casings off of the tube bundle, and servicing the tube bundle.

摘要： A high temperature secondary seal between a rotating seal face adaptor sleeve and a rotating shaft does not consume additional axial space beyond the axial space occupied by the secondary seal. The seal includes a single ring drive collar comprising a plurality of radial directed bolts in tapped holes. As the bolts are tightened they enter a cylindrical cavity in the drive collar and impact therein a sloped surface of a crush ring. The vertical force thereby applied to the crush ring displaces the crush ring axially into a secondary graphite sealing element, thereby crushing the secondary sealing element against the adaptor sleeve and shaft, and forming a seal there between. The crush ring sloped surface can terminate in a vertical face, so that upon sufficient displacement of the crush ring the bolts abut the vertical face and impact the shaft, fixing the drive collar to the shaft.

摘要： A secondary seal of a mechanical seal comprises an annular sealing gasket and backing plate surrounding a cylindrical sealing surface, which all can be made of the same metallic material. The gasket is C-shaped in cross section, and is axially pressed during operation into a C-shaped groove formed in the backing plate that is shallower and larger in inner diameter than the gasket, whereby the gasket, when pressed into the groove, deforms radially inward and seals against both the backing plate and the sealing surface. The contact area between the gasket and sealing surface increases with pressure. In embodiments, when the pressure is released, the gasket retracts from the sealing surface, enabling easy disassembly and allowing axial movement of the gasket and backing plate. Highly polished surfaces of the gasket and sealing surface can allow axial motion thereof during operation to maintain the seal face gap.

摘要： An axial thrust balancing mechanism for a rotating shaft apparatus such as a rotary pump provides self-regulating thrust compensation while avoiding contact and wear between rotating and static elements. A rotor fixed to the shaft includes a cylindrical male section proximal to but not extending within a cylindrical female section of a non-rotating stator, such that a gap formed therebetween is varied in width by axial thrust shaft displacements. Pressurized fluid within the female section applies a thrust-compensating force to the rotor that is controlled by the gap size. The female section is larger in diameter than the male section, preventing any contact therebetween. The disclosed mechanism can be combined with a thrust-compensating drum to reduce the thrust to a residual level that can be regulated. The rotor and stator can be stepwise varied to provide a plurality of gaps and intermediate chambers therebetween.

摘要： A dry running mechanical seal is able to form a direct contact seal for extended periods at both low and high rotational speeds without undue heating or wear of the seal faces. A rear surface of the stator face and corresponding surface of a mounting plate are both lapped for maximum direct contact transfer of heat. Air from a region surrounding the shaft is circulated through a cooling annulus directly behind the stator face and out through exit ports. In embodiments, enlarged scallops or other features on the rotor seal face enhance air turbulence near the seal faces. In various embodiments a surface supporting a dynamic gasket is polished smooth, thereby reducing gasket drag, minimizing the required pressing force between the seal faces, and reducing frictional heating. In embodiments, the rotor seal face shape is optimized to minimize pressure distortions at high pressure.
摘要翻译：干式机械密封能够在低速和高速旋转下长时间形成直接接触式密封，而不会过度加热或磨损密封面。定子面的后表面和安装板的相应表面都被打磨以最大程度地直接接触热量传递。来自轴周围区域的空气通过定子正面后面的冷却环形空间循环并通过出口排出。在实施例中，转子密封面上的扩大扇形或其他特征增强了密封面附近的空气湍流。在各种实施例中，支撑动态垫圈的表面被光滑抛光，由此减少垫圈阻力，最小化密封面之间所需的按压力并减少摩擦加热。在实施例中，转子密封面形状被优化以最小化高压下的压力扭曲。

摘要： A parallel slide gate valve includes a valve body comprising an interior surface, and an obturator therein. A portion of the interior surface defines a groove having a longitudinal axis oriented substantially peipendicular to a direction of flow through the valve body. The groove has a first width at a first end proximate to the fluid flow path and a second width at a second end distal from the fluid flow path, the second width smaller than the first width. The obturator is at least partially within the at least one groove. The obturator is configured to translate from the first end of the at least one groove toward the second end of the at least one groove as the obturator moves from a closed position to an open position.
