摘要： A gripper for a pipe connector includes a body, a first tooth, and a second tooth. The body has a first side, a second side adjacent the first side, a third side adjacent the first side and opposite the second side, and a fourth side adjacent the second side and the third side and opposite the first side. The first tooth extends from the fourth side of the body at a first distance from the first side of the body perpendicular to the first side of the body. The second tooth extends from the fourth side of the body at a second distance from the first side of the body perpendicular to the first side of the body. The second distance is less than the first distance.

摘要： In embodiments, a gate valve includes a body including a flow passage from a first opening to a second opening, and a gate channel from the flow passage to a third opening, the gate channel having a central longitudinal axis and a ridge defining a perimeter of the opening. A valve cover can fit over the third opening and exert a clamping force on the ridge, the clamping force having a first force component perpendicular to the central longitudinal axis and a second force component parallel with the central longitudinal axis. In embodiments, a valve cover includes a first mating surface configured to extend over an opening of the gate valve, a first clamping section extending at a first non-parallel angle from a first side of the first mating surface, and a second clamping section extending at a second non-parallel angle from a second side of the first mating surface.

摘要： A pipe connector includes a body, a cam ring, a seal element, a push ring, and a gripper. The body has an aperture through an outer surface. The cam ring is configured to be located around the outer surface. The seal element is configured to be seated around an inner surface of the body. The push ring is configured to be slideably located within the body, and to have an aperture configured to be aligned with the aperture of the body. The gripper is configured to be located through the aperture in the body and into a first depth of the cam element. The cam ring is configured to rotate, moving the gripper axially to draw the push ring against the seal element and to move the gripper radially to grip the pipe.

摘要： A gate for a gate valve includes a first body portion and a second body portion. The first body portion has a disc shape and a first wedging element extending from the disc shape. The second body portion has a disc shape and a second wedging element extending from the disc shape. The second body portion is pivotably connected to the first body portion. A gate valve includes a valve body and the gate. The valve body includes a first opening, a second opening, a flow passage from the first opening to the second opening, and a gate channel intersecting the flow passage. The gate is configured to move along a center axis of the gate channel between a closed position where the gate is fully in the flow passage to block fluid flow through the flow passage and an open position where fluid can flow through the flow passage.

摘要： A fire hydrant nozzle includes an annular sleeve, which has an annular wall, an inlet end, and an outlet end. The inlet end has a fire hydrant connection element extending from the inlet end and configured to couple with a fire hydrant outlet. The fire hydrant connection element has a portion protruding radially inward, the portion protruding radially inward configured to be moved with respect to the outlet end to connect with the fire hydrant outlet. Another embodiment includes an inlet end and an outlet end, the outlet end configured to couple with a fire hose, the inlet end having a fire hydrant connection element and a first portion with a wall thickness less than a wall thickness of the outlet end. The first portion of the inlet end is configured to be bent to facilitate movement of the fire hydrant connection element into connection with a fire hydrant.

摘要： In an embodiment, a fire hydrant elbow includes a first portion joined with a second portion, the second portion having a center axis angled from a center axis of the first portion. A main valve seat faces radially inward toward the first center axis from the first annular wall, the main valve seat defining a step from a first radius to a second radius, the first radius being larger than the second radius. A guide rib is adjacent the main valve seat between the first portion and the second portion, the guide rib protruding radially inward toward the first center axis.In another embodiment, a main valve seal guide for a fire hydrant includes an annular body and a plurality of guide ribs coupled to the annular body. Each guide rib has a first surface, and each guide rib extends from the annular body to the first surface.

摘要： A fire hydrant barrel includes a body having at least one wall and an anti-rotation pin opening through the at least one wall. The at least one wall defines an internal cavity. The fire hydrant barrel also includes a stem extending through the cavity of the body. The stem has an anti-rotation element, and the anti-rotation pin opening and the anti-rotation element are configured to receive an anti-rotation pin to lock the stem from rotating with respect to the body.

摘要： A limit switch assembly, for a rising-stem valve having a stem with a diameter and a groove marking a desired stem position, includes an actuator arm having an inner end and an outer end. The inner end of the actuator arm forms a follower. A radius washer is mounted to the outer end of the actuator arm. An electrical switch has an operating lever and is mounted adjacent to the outer end of the actuating arm such that when the actuator arm is in an outward position the radius washer moves the operating lever, operating the electrical switch. When the actuator arm is in an inward position the radius washer does not move the operating lever and the electrical switch is not operated. A bias spring biases the actuating arm toward the inward position.
