摘要： A gate valve includes a solid wedge-shaped disc integrated with a cartridge at opposite ends thereof. Each cartridge includes rollers, guides and scrapers therein to roll along respective internal ribs while cleaning the ribs. The disc moves back and forth within the gate valve via the cartridges along ribs to open and close a water passage way formed in the gate.

摘要： A fire hydrant includes an upper barrel, which further includes a body and at least one outlet. The body has a longitude, a longitudinal axis, a first portion, and a second portion, the first portion forming a first length of the longitude, the second portion forming a second length of the longitude, the first portion coupled to the second portion, the body having at least one wall defining an internal cavity. The first portion has a first dimension spanning the cavity perpendicular to the longitudinal axis between opposing points on the at least one wall. The second portion has a second dimension spanning the cavity perpendicular to the longitudinal axis between opposing points on the at least one wall. The first dimension is greater than the second dimension.

摘要： A cushioned check valve includes a flow channel with an inlet, a check valve, and an outlet. Bypass channels connect the outlet, a cylinder containing a piston, and the inlet. The piston is biased toward a first end of the cylinder by a diaphragm and a hermetically sealed gas volume containing a compressible gas, blocking the bypass channels. When the fluid pressure in the outlet exceeds a nominal operating range, the piston moves toward a second end of the cylinder until the fluid pressure acting on the piston is equalized by the piston bias, and fluid flows through the bypass channel. Once the fluid pressure and piston bias are equalized, the piston returns to a position blocking the bypass channels.

摘要： An expanding disk gate valve assembly comprises two gate disks and an elastomeric disk. A first flange on a first gate disk mates to a second flange on a second gate disk forming an internal volume surrounding the elastomeric disk. An elastomeric sheath covers the mated disks with the first gate disk being radially offset from, and radially movable relative to, the second gate disk. A width of the gate disk assembly is less than a width between two valve seats when the gate disk assembly is in an open position. In a closed position, the first flange moves radially toward the second flange, compressing elastomeric disk, and causes the elastomeric disk to expand axially against the two gate disks, forcing them apart, and increasing the gate disk assembly width so that the gate disk assembly actively seals against the valve seats.

摘要： A butterfly valve seal arrangement in a butterfly valve having a cylindrical flow channel with a wall includes a seal flange, an elastomeric seal, a seal channel, and an annular seal retaining ring. The seal flange extends into the cylindrical flow channel from the wall of the cylindrical flow channel. The seal channel is recessed into the wall of the cylindrical flow channel adjacent to the seal flange. And the annular seal retaining ring includes tabs extending into the seal channel which hold the annular seal retaining ring in the cylindrical flow channel. An elastomeric seal is held in compression in the seal channel and against the seal flange by the annular seal retaining ring, and extends into the cylindrical flow channel forming a seal surface held in compression against a vane seat of a vane in a position perpendicular to a direction of flow.

摘要： A hydrant main valve includes a main seal elastically deformable between a first state and a second state, such that a main valve assembly may be inserted into a main valve elbow without removable valve seats. A main valve assembly rotation lock engages a rotation block inside the elbow preventing rotation of the main valve assembly. A rotating operating stem extension moves a main valve bottom plate relative to a drain valve body, causing main valve seal elastic deformation.

摘要： A drain valve slide and drain valve facing seal an elbow drain hole in a dry barrel fire hydrant when the main valve is closed. A first wedge on the main valve assembly engages the elbow when the main valve is opened and biases the drain valve slide and drain valve facing toward the elbow drain hole, creating a positive seal.

摘要： A mud valve having a flange frame and yoke that are permanently connected to form a single unit without the aid of removable fasteners is described. Installation of the drain plug is facilitated by an arrangement of guide tabs on either side of the drain plug that are of different distances from the surface of the drain plug. This staggered arrangement allows the drain plug to be installed through a tilting and rotating of the drain plug that brings the tabs into alignment with guide rails on the yoke without necessitating the separation of the yoke from the flange frame. Similarly, the construction described allows the drain plug to be removed for repair or replacement in the field without disassembling the yoke and flange frame.
