Abstract
A covering is provided to protect nozzles from outdoor elements while allowing the nozzle to discharge fluid when needed. The covering includes a water way portion with a cap, a lock ring, a clamp, and a flexible collar, and may also include a body cover attached to the water way portion and extending over the body of the nozzle. The cap is configured to cover the water way of the nozzle and is attached such that when pressure is applied from the water way, the cap is released allowing water to flow from the nozzle. The cap may then be reattached to the collar when the nozzle is not is use. In this way, the cover protects and covers fire nozzles up to the moment that the equipment is activated.
Claims19
A protection system for a nozzle having a body with an inlet end and a discharge end with an opening, the opening including an outer nozzle opening surface having an outer diameter, comprising:
- a flexible collar sized and configured to fit around a portion of the body at the discharge end and including a collar engagement member on an end facing the discharge end when the flexible collar is on the body;
- a lock ring sized and configured to fit over the discharge end and a portion of the flexible collar, the lock ring including a receptor configured to receive the collar engagement member;
- a clamp sized to fit around the flexible collar when the flexible collar is on the body and configured to tighten the flexible collar onto the body;
- and
- a cap sized and configured to cover the opening and be releasably attached to the lock ring and disengage from the lock ring when a threshold pressure is exerted on a nozzle-facing surface of the cap from the discharge end,
- wherein the lock ring is configured to remain attached to the body when the cap disengages when the threshold pressure is exerted.
A method of protecting a nozzle having a body with an inlet end and a discharge end with an opening, the opening including an outer nozzle opening surface having an outer diameter, comprising:
- placing a flexible collar around a portion of the body at the discharge end, wherein the flexible collar includes a collar engagement member on an end facing the discharge end;
- placing a lock ring over the discharge end and a portion of the flexible collar, wherein the lock ring includes a receptor that engages with the collar engagement member;
- tightening a clamp around the flexible collar such that the flexible collar is secured to the body;
- and
- attaching a cap to the lock ring, wherein the cap covers the opening and is attached to the lock ring such that the cap disengages from the lock ring when a threshold pressure is exerted from the discharge end on a nozzle-facing surface of the cap;
- wherein the lock ring is configured to remain attached to the body when the cap disengages when the threshold pressure is exerted.
