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： A gate valve includes a valve body including a gate channel intersecting a flow passage that extends from a first opening to a second opening. In embodiments, the gate channel has a width constant across a length extending from an intersection of the flow passage and the gate channel away from the flow passage. In embodiments, the flow passage is defined by a perimeter surface, a semi-annular slot through the perimeter surface, and a center axis through a center of the first opening and the second opening, the semi-annular slot extending on both sides of a first plane, the first plane perpendicular to a center longitudinal axis of the gate channel, the first plane parallel to and intersecting the center axis of the flow passage. In embodiments, the flow passage has an outer diameter, and a span of the gate channel containing the diameter is greater than the outer diameter.

摘要： Provided is an adapter and a method of making the same. The adapter includes threads to connect a fire hydrant to one end of a fire hydrant elbow having a different scale than the fire hydrant, the fire hydrant elbow being connected at a second end to an underground water pipe. The adapter also includes at least one stainless steel tube extending at a first end thereof from a corresponding at least one port hole formed through a lower end of an inner surface of the adapter and a second end thereof extending through a corresponding at least one port hole formed through an approximate middle portion of an outer surface of the adapter. The corresponding port holes through the inner surface of the adapter and the outer surface of the adapter being in vertical alignment.

摘要： A limit switch assembly for a rising-stem valve includes an operating lever actuator element mounted to an outer end of an actuator arm. An electrical switch mounted adjacent the outer end has an operating lever. When the actuator arm is in an outward position, the operating lever actuator element retains the operating lever in a first position wherein the electrical switch is in a first state, and when the actuator arm is in an inward position the operating lever is in a second position wherein the electrical switch is in a second state. An adjustment nut is mounted to the outer end adjacent the operating lever actuator element, and the operating lever actuator element and the adjustment nut are configured to be adjusted along a longitude of the actuator arm to change a distance the operating lever actuator element must travel to move the operating lever into the first position.

摘要： A wrench for securing, actuating and preventing tampering with a fire hydrant is disclosed. In useful embodiments, the wrench can be a two-ended wrench having a loop that encloses a pentagonal opening at either end of an elongated handle, where the handle can include in a nonterminal portion a slot. In a locking mode, the wrench can accept at a first end an actuating nut of the fire hydrant and can be locked in place by inserting a locking arm of a padlock through an eye bolt that is secured to a side of the fire hydrant and inserted through the slot. The wrench can be unlocked and removed, whereupon a second end can be used to turn the actuating nut as well as to remove water outlet caps and adjust nozzles.

摘要： A fire hydrant stem includes a shaft having a center axis, a first end portion, a first end, and a second end. The first end portion extends axially a length from the first end, has external threads, and defines an internal cavity open through the first end. The second end is configured to engage a fire hydrant main valve operating assembly. A fire hydrant upper stem assembly includes a fire hydrant stem and a spring element. The fire hydrant stem defines an internal cavity, and the spring element is in the internal cavity.

摘要： A cushioned relief valve includes a housing, a piston, a cylinder cover, and a flexible diaphragm. The housing has an inlet, an interior, an outlet channel, and an outlet, the interior being a hollow cylinder in fluid communication with the inlet and the outlet channel, the outlet channel extending from a cylindrical side of the hollow cylinder to the outlet, the outlet opening outside the housing. The piston is located within the hollow cylinder and is slidable between a first position blocking the inlet and the outlet channel, and a second position opening a path for fluid flow between the inlet and the outlet channel. The cylinder cover defines a compressible gas volume in fluid communication with the second end of the hollow cylinder. The flexible diaphragm separates the compressible gas volume of the cylinder cover from the second end of the hollow cylinder.
