摘要: A dual plate backflow and breakaway check valve that features a warning system to alert individuals when fire hydrants are dislocated. The dual plate check valve comprises an upper surge protection valve assembly and a lower backflow protection valve assembly. When fire hydrant or pipes conveying fluids are damaged, the locking mechanism enables a plurality of upper witness stream holes to generate at least one plume of fluid to indicate and readily visualize location of damage and allows an upper barrel assembly to operate in a closure mode. In this mode, a high pressure spray of fluid emits from the upper valve barrel and an optimum inclination of the lower portion of the upper valve barrel enables the upper witness stream holes to collide with an inner side wall of the upper valve barrel which causes the plurality of upper witness stream holes to disperse into a warning signaling mist.

摘要: A dual plate backflow and breakaway check valve designed to mount above grade. The dual plate check valve includes a barrel assembly having an upper portion, a lower portion and an annular groove. An upper dual valve includes an upper front plate and an upper back plate. A lower dual valve includes a lower front plate and a lower back plate. A lower valve keeper bar moves up from between a plurality of lower valve stay tabs upon breakage of the annular groove thereby allowing the lower front plate and the lower back plate to rotate about a lower valve pin and closing the lower dual valve upon a lower barrel bevel and simultaneously allowing the upper front plate and the upper back plate to rotate about an upper valve pin and closing upon an upper barrel bevel.

摘要: A break-away check valve is disclosed. The check valve may be configured between two passageways and may regulate the flow of liquid between the passageways. The check valve may include an actuation assembly that may actuate the check valve upon the system becoming dislodged or otherwise dislocated from at least one of the passageways.
