摘要： A valve trim apparatus comprises a valve seat (216) and a closure member (214) to operatively engage the valve seat (216). One of the closure member (214) and the valve seat (216) includes a plurality of annular ribs (222), and at least one of the valve seat (216) and the closure member (214) defines at least one groove (218) to be positioned between at least two of the annular ribs (222) to receive material from a sealing surface (220) between the closure member (214) and the valve seat (216) when the closure member (214) is sealingly engaged with the valve seat (216).

摘要： The invention relates to a device for selectively blocking a fluid passage, particularly for a tap-filling intake, including a structure defining a channel for the passage of a fluid extending between an inlet at an upstream end and an outlet at a downstream end, a valve seat, a valve selectively mobile in the channel between a first position for blocking the passage by sealingly bearing on the seat and a second position for opening the passage in which the valve is not sealingly bearing on the seat, wherein the blocking device includes a deformable seal, supported by the mobile valve and/or the seat, for bearing against the seat and ensuring the seal of the blocking when the valve is in the first position, characterised in that the mobile valve includes a main body and a stop mobile relative to the main body, the main body and the mobile abutment defining a mechanism for selectively pressurising the seal and movable between a working position for pressuring the seal for increasing the force thereof on the seat and a rest position in which the pressure on the seal is released so as to reduce the force thereof on the seat.

摘要： A sealing microsawtooth ring joint, made between a toothed seating surface and a full plain seated surface by a microsawtooth ring with its tooth crest on the seating surface being a cutting edge whose corner or whose crest angle is about 90°~120°, with its tooth height Z t being about 10~20 times the roughness R a of the seated surface, and with the ratio of its tooth pitch X s to its tooth height Z t being 20~500 to ensure that the tight joint has a microcosmic line contact followed by a surface contact or to ensure that the tight joint has both such a line contact as to be able to provide a necessary seating stress locally and such a surface contact as to be able to protect the line contact from being excessively pressed to get blunt or disappeared, can be used either as a pressure-tight joint or as a self-energizing tight joint of any two surfaces such as flats to flats, cones to cones or spheres, spheres to spheres or cones etc., thus simplifying and unifying the designing, calculating, manufacturing, selecting, installing and maintaining of fussy gaskets for a tight joint of flat surfaces, avoiding the lapping of formed jointing surfaces without using soft gaskets, increasing the reliability of tight joints and the utilizing coefficient of natural resources. The sealing microsawtooth ring joint can still have an extra sealing reliability and safety sensation by selectively adding one of four basic gland seals.

摘要： Die Erfindung betrifft ein Kugelsitzventil 1 zur Einstellung eines Durchflusses eines fluiden Mediums, aufweisend einen Ventilsitz 6 und ein abgerundetes Schließelement 4, insbesonere eine Ventilkugel, weiterhin aufweisend einen Einlauf 7 mit einer Vordrossel 9, und einem zwischen der Vordrossel 9 und dem Ventilsitz 6 angeordneten Diffusor 10, wobei der Einlauf 7 eine Verengung aufweist. Erfindungsgemäß wird ein Kugelsitzventil 1 bereitgestellt, bei dem die Gefahr einer Erosion im Bereich des Ventilsitzes 6 reduziert ist. Dies wird dadurch erreicht, dass die Verengung einen Kegelstumpfabschnitt 11 mit einem scharfkantigen Absatz 13 auf der dem Ventilsitz 6 zugewandten Seite aufweist und ein Diffusorventilsitzabschnitt 12 oberhalb des Absatzes 13 fasenlos in den Ventilsitz 6 ausläuft.

摘要： The magnetically actuable valve has an interior space (10) which is surrounded by a magnetizable wall (11) and in which a valve body (15) can move, closing a valve opening (14) in the closed position. The magnetic circuit includes at least one intermediate piece (20) made from nonmagnetic material, while the wall (11) and the valve seat (13) consist of magnetizable material. As a result of the valve body (15) being arranged eccentrically or as a result of the intermediate pieces being arranged asymmetrically, the magnetic flux density is increased on one side, so that the valve body moves onwards towards this side from the valve opening (14).

摘要： A canister type flush valve has an upright cup-shaped hollow float (30) working under buoyancy forces without a captured air volume that controls the valve during a flush cycle. Hooded bleed openings (70) at a bottom wall of the float can be sized and numbered to selectively control the closuring timing of the valve. Baffles (72) of the hood bleed openings redirect water bleeding into the float to prevent the water from spraying up against the top of the tank. The geometry of a seal retaining groove (80) is designed to reduce leakage at the float/seal interface. For example, the groove has an annular wall with a compound profile forming a non-cylindrical, preferably serpentine, seal contact area (96). The seal is backed by a slotted flange (82) located just above the retaining groove.
