TECHNICAL FIELD

This disclosure relates to fire hydrants. More specifically, this disclosure relates to a spacer for a hydrant nozzle cap.

BACKGROUND

Fire hydrants are commonly connected to fluid systems, such as municipal water infrastructure systems and water mains, through standpipes. A leak detection system may be provided for detecting leaks in the fluid system and can be attached to a nozzle cap, and the nozzle cap be attached to a nozzle of the fire hydrant. Leak detection systems often comprise an antenna, which should be appropriately oriented for ideal transmission and reception of signal. A gasket may be positioned between the nozzle cap and the fire hydrant to adjust the rotational indexing of the nozzle cap relative to the fire hydrant, thus adjusting the orientation of the antenna.

In some fire hydrants, such as some wet barrel hydrants, a leak path might be provided in the nozzle cap to allow water or air to leak out the nozzle cap, relieving pressure between the nozzle and the nozzle cap when the nozzle is closed after use. In some aspects, the leakage of water out of the nozzle cap can indicate that a valve within the nozzle is not fully closed. However, a gasket for sealing the nozzle cap with the nozzle can resiliently deform into the leak path, blocking water from draining out of the nozzle cap and preventing the pressure therein from being reduced.

SUMMARY

It is to be understood that this summary is not an extensive overview of the disclosure. This summary is exemplary and not restrictive, and it is intended neither to identify key or critical elements of the disclosure nor delineate the scope thereof. The sole purpose of this summary is to explain and exemplify certain concepts of the disclosure as an introduction to the following complete and extensive detailed description.

Disclosed is a nozzle cap spacer for a hydrant nozzle cap comprising a spacer body defining an outer body edge; and a resilient first spacer spring arm extending from the outer body edge, wherein the first spacer spring arm is biased away from the spacer body in an extended orientation.

Also disclosed is a spaced nozzle cap assembly comprising a nozzle cap comprising a cap body, the cap body comprising a bore sidewall defining a threaded bore; and a nozzle cap spacer comprising a spacer body and a spacer spring arm extending from the spacer body, the nozzle cap spacer received within the threaded bore, the spacer spring arm engaging the bore sidewall.

Also disclosed is a method for adjusting a rotational indexing of a nozzle cap, the method comprising providing a nozzle cap and nozzle connector, the nozzle cap defining a threaded bore; inserting a nozzle cap spacer into the threaded bore to adjust a rotational indexing of the nozzle cap relative to the nozzle connector; and connecting the nozzle cap to the nozzle connector.

Various implementations described in the present disclosure may include additional systems, methods, features, and advantages, which may not necessarily be expressly disclosed herein but will be apparent to one of ordinary skill in the art upon examination of the following detailed description and accompanying drawings. It is intended that all such systems, methods, features, and advantages be included within the present disclosure and protected by the accompanying claims.
