摘要： A gate valve comprises a valve body (1) and a gate displaceably arranged inside said valve body transverse to the flow direction, said gate being provided on each side with a guide groove (14) guided by means of a mating guide rail formed on each side of the valve body (1). The gate (13) comprises a gate core (16) coated with a polymeric material, preferably an elastomer, which in the sealing surface areas (17, 18) of the gate (13) sealingly abuts the corresponding seat surfaces (19, 20) of the valve body (1) in the closed position of the gate. At least the guide grooves (14, 44) are coated with a harder and more wear-resisting polymeric material than the remaining portion of the gate, and the two coatings are moulded such that a molecular interbinding exists between said coatings in the transition areas therebetween.

摘要： An improved percussor assembly comprises a rigid body member having gas inlet and gas outlet means, the latter including a restricted passageway and an enlarged passageway, and a vent passageway communicating with the enlarged portion adjacent the junction of the restricted passageway whereby atmospheric air is entrained into the enlarged passageway as gas flows therein from the restricted passageway thereby increasing the volume of gas supplied to a remote applicator while economizing on the amount of pressurized gas required to operate the percussor. The vent passageway also relieves gas pressure from a remote pneumatic applicator between successive bursts of gas from the percussor assembly. An improved remote applicator having means for selecting the force of the percussive bursts is also provided.

摘要： The gate valve comprises a body having a horizontal flow passageway, a vertical housing opening into the flow passageway and a closure member movable in the housing and passageway. The closure member has on each side a vertical U-shaped guiding bearing surface which projects from a sealing bead on the closure member and extends from the lower end of the closure member to a region located above the equatorial plane of the valve. This bearing surface permanently cooperates with a vertical bearing surface provided in the body between the flow passageway and a seat surface and having, when viewed along the flow axis a downwardly open C-shape.

摘要： An expanding gate valve having a pressure-secured seat. The valve includes a valve body having a cavity formed therein and an inlet and outlet formed in the body, both of which intersect the cavity. A counterbore is formed about the circumference of both the inlet and the outlet at their respective intersections with the cavity. An annular seat having a rear surface and a front seat surface is received within the inlet counterbore. An annular seal is formed on the front seat surface and a second annular seal is disposed between the rear surface and the valve body. The front annular seal has a sealing diameter greater than the rear annular seal and an annular recess is formed on the front seat surface on the radially inward side of the annular seal. A second annular seat having a planar front seat surface is received within the outlet counterbore. An expandable gate is mounted for selective vertical positioning in the cavity for permitting flow between the inlet and outlet in one position and for sealing off such flow in another position. When in position for sealing off such flow, the gate is expanded into sealing engagement with the first and second seats.

摘要： Disclosed is a valve in which the valve internals, the valve seat, guides and slide valve are maintained in position solely by a clamping action of a quick make-up cylinder having an inlet flow passage into the valve. The valve is particularly suited for small valves as no screws or other fasteners are used to maintain the valve internals in position. Advantageously, the guides and slides are maintained out of the flow path, and the valve internals, including the cylinder, are readily removable through the bonnet area.

摘要： A shower-tub diverter valve has a housing with a diverter chamber and a water inlet and shower and tub outlets in communication with the chamber. A diverter formed of a stem and a loosely attached cylindrical member are reciprocal in the chamber between a position providing communication between the inlet and the tub outlet, and a second position in which the diverter cylindrical member blocks said communication. The diverter cylindrical member is in substantial sealing relation with the tub outlet when in the blocking position. The cylindrical portion of the diverter is movable relative to the stem and the diverter chamber includes guide means for use in aligning the diverter cylindrical portion as it moves between the described positions.
