    摘要: Valve having a valve housing, a valve member slidable in the valve housing between open and closed positions, and a friction reducer to reduce friction between the valve member and the valve housing. The friction reducer comprises at least one guide shoe made of low friction material, to provide a low friction sliding surface, the guide shoe being removably insertable into a slot in the valve member. The guide shoe is arranged to cooperate with the slot such that the ends of the slot prevent the guide shoe from being extracted from the valve member in the direction of movement of the valve member, when the valve member is in position with the valve housing.

    摘要: A sliding plate of a gate valve is guided in guide grooves formed in the region of a flow passage of the two-part gate valve housing. Each guide groove is bounded on both sides [upstream and downstream] by guide strips which extend into the flow channel. The guide strips have axially outwardly directed chamfers, and each such strip has a circular arcuate shaped recess. The recess, which starts at the upper entry point of the guide groove into the flow channel, extends to the lower third of the guide strip. The maximum depth of the recess is 3-5 mm less than the depth (t) of the guide groove 4b. The guide grooves 8a, 8b provide problem-free guiding of the sliding plate when said plate is moved to its closed position, particularly when said plate is moving through the lower third of the flow channel; nonetheless, the guide grooves 8a and 8b present only minimal flow resistance. When the sliding plate is being closed, material which may have deposited in the relatively short parts of the grooves which parts are not affected by the recess, can be expelled without problems via the closing-edge of the sliding plate.

    摘要: A guide slot for a valve plate is bounded on both sides by guide strips projecting into a flow channel of a valve housing for the plate. These guide strips contain notches at intervals. The notches of one guide strip are offset relative to the notches of the other guide strip. When the valve is open, medium entering the guide slot through the notches on the inflow side is deflected in the guide slot before it leaves the guide slot again through the offset notches on the outflow side. This generates in the guide slot a lengthwise current leading to a self-cleaning action for combatting deposits. During the valve plate closing process, a permanent self-cleaning takes place over the entire closing travel zone. For this reason, the valve is particularly well suited for use in conveyor lines for thickish, powdery, granular or solids-containing media.

    摘要: A shutoff wedge for a shutoff valve has a U-shaped sliding shoe of synthetic plastic material with good sliding properties, high wear resistance, and sufficient temperature strength, which is inserted in guiding grooves of the shutoff wedge which is sealingly enclosed by a rubber elastic jacket up to the sliding faces abutting against guiding strips of a shutoff valve housing. A method of anchoring of the synthetic plastic sliding shoe and a mold therefor are also provided.

The improved stem sealing assembly includes a U-shaped resilient seal ring with means in its open end to ensure sealing engagement of the multiple internal and external sealing lips with the stem and body sealing surfaces and support rings positioned in grooves between the sealing lips and anti-extrusion means engaging the closed end of the seal ring to prevent extrusion of the seal ring. A modified sealing assembly also includes a back-up seal and anti-extrusion means therefor.

    摘要: Disclosed is a slide valve in which the valve internals, the valve seat, guides and slide valve are maintained in position by a clamping action of an abutment in the valve body and on the valve liner secured in the body by a quick make-up connection. The slide valve is suited for all sizes of valves, both large and small and no screws or other fasteners are needed to maintain the valve internals in position. Advantageously, the guides and slides of the slide valve are maintained out of the flow path, and the valve internals including the orifice assembly with its valve seat and guides, and slide valve with its slides are readily removable through the bonnet area.
