摘要： There is disclosed a gate valve having a cast body which is of sufficiently low height that the upper end of the gate remains partially within a cavity in the bonnet connected to the body as it moves between opened and closed positions. Guide surfaces are formed in the open end of the bonnet cavity for guiding the side edges of the gate as it is so moved. The stem is of a non-rising type having a ring mounted for rotation without reciprocation between upper and lower axial thrust bearings in the bonnet and connected to a one-piece stem by means of a pin which is adapted to shear in response to a predictable axial load on the stem.

摘要： A gate valve apparatus suitable for controlling the flow of fluids in a conduit, especially gases in high temperature applications, is disclosed. The apparatus includes a gate member adapted for sliding movement through an aperture in the gate valve assembly. Each opposing side of the aperture has fixedly mounted cooperating flat sealing strips to seal the aperture in both the conduit-open and conduit-closed positions. In certain embodiments a plurality of substantially parallel gate members, each having aperture sealing means, may be used to provide increased sealing effectiveness for highly toxic gaseous mediums.

摘要： The valve of the present invention includes an inflatable seal element located in the housing seat and a gas-pressure-purge arrangement. The inflatable seal element is inflated by means of pressurized fluid to grow in size and close up clearances between gate and seat, thereby establishing a gas-tight seal between the two parts, at will. So this can be done, for example, after the valve has been operated to close (slide gate driven into the valve housing) and a gas-pressure-tight seal is desired. Prior to this event, the gas-pressure-purge arrangement is activated to blast-off solid particles from the gate surfaces where these make contact with the inflatable seal element. It is not mandatory that each and every solid particle be removed from the gate contact surfaces by means of the gas-pressure-purge arrangement. Only a reasonable amount of cleanliness on the gate contact surfaces is desirable. The inflatable seal element is capable of sealing gas-tight even when some solid particles become trapped and embedded on the inflatable seal surface. The purpose of the gas-pressure-purge arrangement is to keep the contact surfaces reasonably free of solid particles only to improve the life of the inflatable seal element. Furthermore, the inflatable seal element can be deflated to shrink in size, thereby providing increased clearance between gate and seat, when desired. So this is done just prior to the moment when the gate is to be operated (driven out of the housing) to open the valve. No scoring can occur on gate or seat on account of the increased clearance.

摘要翻译： 本发明的阀包括位于壳体座中的可膨胀密封元件和气体压力清除装置。 充气密封元件通过加压流体膨胀以增大尺寸，并且关闭门和座之间的间隙，从而在两部分之间随意建立气密密封。 因此，例如，在阀已经操作以关闭（滑动门驱动到阀壳体中）之后，可以进行这种操作，并且需要气密密封。 在此事件之前，气体压力吹扫装置被激活以从门表面吹出固体颗粒，这些颗粒与可膨胀的密封元件接触。 通过气体压力清除装置，不必强制每个固体颗粒从栅极接触表面上除去。 在栅极接触表面上仅需要合理的清洁度是理想的。 即使当一些固体颗粒被捕获并嵌入在可充气密封表面上时，该充气密封元件也能够气密地密封。 气体压力吹扫装置的目的是使接触表面合理地不含固体颗粒，以改善可充气密封元件的使用寿命。 此外，充气密封元件可以放气以缩小尺寸，从而当需要时在门和座之间提供增加的间隙。 所以这是在门被操作（从外壳驱动出来）打开阀门之前完成的。 由于增加的清关，不得在门口或座位上发生得分。

摘要： A packingless gate valve comprises a housing having two opposed resilient sleeve units that compressibly engage end to end in valve open condition and engage opposite sides of the gate in valve closed condition. Each sleeve unit is a resilient annular body formed at one end with an axially projecting seal lip near the inner periphery and has a bonded stiffening and gate guide element around the outer periphery at the one end. An integral gasket forming flange is formed on the other end of the sleeve body.

摘要： A gate valve structure having a pair of opposed spacer carriers (72,74) fitting within the valve chamber in abutting relation to each other and spacing the floating upstream and downstream seats (60, 62) from each other a predetermined minimum distance. Each carrier (72, 74) has an annular base (76) adjacent one of the flow passages and a pair of spacers or guides (78, 80) secured to the base and extending from the base (76) in a direction axially of the flow passage. The spacers (78, 80) on opposed carriers are in abutting relation to each other and form a smooth continuation. An expanding gate assembly (28) fits between the spacers and moves between open and closed positions relative to the flow passages.

摘要： A gate valve structure for use in mains carrying a fluid under high pressure, the fluid being of the type which could possibly cause corrosion to the elements of the gate valve structure including the casing. An improved valve gate member is provided which permits operation from closed to open position and vice versa with a minimum of torque and with maximum holding power in the closed position. The valve gate member is designed so that there is unobstructed communication between the ports of the valve casing to thereby reduce turbulence and currents within the valve structure and thus effectively reduce corrosion deposits and collection of debris within the structure. The valve gate member is a flat and hollow chamber for reception of a valve operating stem and means are provided to completely protect the valve gate member and the track in which it operates from corrosion and possible damage.
