Curb box and method
A curb box for underground gas and water services includes a tubular member such as a pipe that extends from a valve in an underground line up to surface. A resiliently flexible tubular member segment is installed in the tubular member between an uppermost end of the tubular member and a lower portion of the tubular member. The resiliently flexible tubular member segment allows the uppermost end to resiliently flex relative to the lower portion. As such, if impacted, the uppermost end can resiliently yield at the resiliently flexible tubular member, thereby preventing the tubular member from being bent and rendered inoperable as a conduit to the valve in the underground line.
Hydrant cap with retainer
A hydrant includes a hydrant body defining a top end and a bottom end distal from the top end, the top end defining a barrel diameter and an opening; and a hydrant cap defining an upper surface facing away from the hydrant body and a lower surface facing toward the top end of the hydrant body, the hydrant cap defining a cap diameter, the cap diameter being greater than the barrel diameter; and a cap fastener, the hydrant cap secured to the top end of the hydrant body with the cap fastener, a portion of the cap fastener extending through the opening defined in the top end of the hydrant body.
FIRE HYDRANT NOZZLE
A fire hydrant nozzle includes an annular sleeve. The annular sleeve has an annular wall, an inlet end, and an outlet end. The inlet end has a fire hydrant connection element configured to couple with a fire hydrant outlet, the outlet end has a fire hose connection element configured to couple with a fire hose, and the fire hydrant connection element has a portion protruding radially inward.
FIRE HYDRANT
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.
FIRE HYDRANT
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.
BREAKER CLAMP FOR FIRE HYDRANT
A breaker clamp member includes a curved body shaped to fit around a portion of an upper portion of a fire hydrant and a portion of a lower portion of the fire hydrant at a joint between the upper portion of the fire hydrant and the lower portion of the fire hydrant. The breaker clamp member also includes at least one connection element extending from the body to connect the breaker clamp member with at least one other breaker clamp member. The breaker clamp member also includes an upper rim protruding from the body and a lower rim protruding from the body. The upper protruding rim, the lower protruding rim, and the body define a concavity therebetween, the concavity being configured to receive the first ledge and the second ledge. In another embodiment, a breaker clamp includes two breaker clamp members.
Fire hydrant
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.
BREAK-AWAY TRAFFIC FLANGE FOR A HYDRANT
A traffic flange for a hydrant includes: a body portion defining an arcuate shape and including an upper surface, a lower surface, an inner radial surface, and an outer radial surface, the body portion defining a body portion width in a radial direction relative to a main axis of the traffic flange, the body portion further defining a plurality of holes extending in an axial direction of the traffic flange relative to the main axis from the upper surface to the lower surface; and a break-away portion including a plurality of tabs extending radially inward in the radial direction from the inner radial surface of the body portion, a total width of the traffic flange in the radial direction of the traffic flange at each of the plurality of tabs greater than the body portion width.
FITTING WITH MAINTENANCE OPENING
A fitting for shutting off and/or regulating flows of substance for use in pressure ranges above 50 bar has a housing body and a valve disc which can be operated from a drive lying outside the housing body via a valve shaft. The housing body is provided with a maintenance opening that can be shut off in a pressure-tight manner by a self-sealing lid that has a seal. In order to allow objects that are as large as possible, in particular the valve disc, to be guided through the maintenance opening during inspection works, without increasing the weight of the housing body, the maintenance opening has a rectangular passage cross section. In contrast to known circular maintenance openings which are known in this pressure range, a rectangular passage cross section permits a smaller surface area for the passage cross section and therefore a lighter housing body.
