A method of manufacturing a main valve of a hydrant includes: forming an internal rigid structure including a top surface, a bottom surface, a side surface, and a locating feature, the locating feature defined in a one of the top surface and the bottom surface; positioning the internal rigid structure in a mold by contacting the locating feature with the mold; and forming an outer shell around the internal rigid structure.

The present disclosure provides shortening prevention sleeves for adjustable underground utility boxes, underground utility boxes including such sleeves, and methods of preventing shortening of underground utility boxes with such sleeves. A sleeve comprises a substantially rigid elongate tube that defines an internal cavity. The tube is configured to allow a stem portion of an adjustable underground utility box to extend fully therethrough via the internal cavity. The sleeve also comprises an opening that extends along the length of the tube and provides a passageway into the internal cavity. The tube is configured to allow the stem portion of the box to pass through the opening and into the internal cavity. The sleeve is configured to extend over and along the stem portion and between enlarged top and bottom portions of the box to prevent the stem portion, and thereby the box as a whole, from shortening.

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.

The disclosure teaches an adjustable/extendable piping system/module for associating fluid access products (such as fire hydrants) to a buried fluid source. The piping system defines an adjustable configuration that allows for the overall length of the piping system to be modified to compensate for different bury depths. The disclosure further teaches a flex module configured for associating a fluid product with a piping system connected to a fluid source. The flex module is configured to flex a predefined amount to prevent damage to the system from low energy impacts.

A hydrant includes a standpipe, a discharge nozzle, and a subterranean valve operated by a valve stem. The operating stem is hollow and has an inlet at its lower end and a drain outlet at its upper end, thereby providing a path to flush the sampling station when the subterranean valve is shut and the discharge nozzle and drain outlet are open by applying a differential pressure. The subterranean valve includes a cartridge having a fixed portion and a moveable portion. The fixed portion is fixed to the end of the stem and turns with it but does not move axially. The moveable portion moves axially but does not rotate. The fixed and moveable portions are connected to each other by a threaded connector. The cartridge, including a valve plug, a valve seat, and a threaded operating mechanism can be removed simply by removing a top cap on the standpipe.

An opening tool for a locking cap of a fire hydrant includes a collar with multiple protrusions that can attach to corresponding protrusions provided on an outer surface of the locking cap. The opening tool also includes a main support portion coupled to the collar, a guide supported by the main support portion, the guide including a shaft support, a pin moveably disposed within the guide and a cam lever rotatably coupled to the guide by a shaft. The shaft extending through the cam lever. The shaft being supported by a shaft support. The cam lever including a cam surface in contact with a first end of the pin. The cam surface including a first flat surface, a second flat surface and a curved surface that extends between the first flat surface and the second flat surface.

Provided is an enclosure with an integrated hydrant. The enclosure includes a fluid flow conduit that transfers fluid from a fluid supply tube to a fluid outlet, which may be associated with the backflow preventer. The enclosure has a conduit that carries water from the fluid supply tube to the backflow preventer. Thus, a lower profile, lighter, and more aesthetically pleasing enclosure is provided.

A hydrant device includes a faucet body, a rotation shaft, an upper rotation cap, a check valve, a switch valve, a lower fixed cap, and a water intake seat. The faucet body is provided with a rotary knob connected with the rotation shaft which is connected with the upper rotation cap. A first elastic member is biased between the rotation shaft and the upper rotation cap. A second elastic member is biased between the upper rotation cap and the check valve. The check valve is provided with a stop face. The switch valve is combined with the upper rotation cap. The water intake seat is mounted on the faucet body. Thus, the stop face forms an anti-reverse state to seal the switch valve, thereby preventing water from being gathered in the switch valve.

An infrastructure monitoring assembly includes a nozzle cap, the nozzle cap comprising a metallic material; an antenna cover, the antenna cover attached to the nozzle cap, the antenna cover comprising a plastic material, the antenna cover defining an antenna cavity; and an antenna extending into the antenna cavity. An infrastructure monitoring assembly includes a fire hydrant, the fire hydrant defining a nozzle; a nozzle cap, the nozzle cap comprising a metallic material, the nozzle cap attached to the nozzle and sealing the nozzle; an antenna cover attached to the nozzle cap, the antenna cover comprising a plastic material, the antenna cover defining an antenna cavity; and an antenna disposed within the antenna cavity.
