Abstract

A fully serviceable frost proof mixing hydrant for supplying water at various temperatures to the exterior of a building. The mixing hydrant includes hot and cold water inlets and a chamber in which the water is mixed based on the position of a cammed wheel acting on a pair of poppets. These poppets act as temperature regulators and check valves to prevent cross-flow leakage and/or contamination. The mixing hydrant includes an inside tube or flow sleeve for delivery of water to an outside body tube in communication with a spout on the head of the hydrant. The flow from the inside tube to the outside body tube reduces turbulence and provides a better outlet flow from the spout. Flow control and temperature control are independent allowing the user to set the flow as desired then adjust the temperature as desired without affecting the flow. A turbulence reducer may be integrated in the vacuum breaker prevents leakage during use of the hydrant by reducing turbulence acting on the vacuum breaker poppet. Additionally, the user is able to service all aspects of the hydrant from outside the building

Claims22

Dependent claims

A mixing hydrant comprising:

a head, a valve body, a valve temperature regulator assembly, and hot and cold water inlets;
said head having a flow control knob, a temperature control knob, and a spout;
said valve temperature regulator assembly having a housing, a poppet valve body received in said housing, said poppet valve body having a hot water inlet nipple coupled to said hot water inlet, a cold water inlet nipple coupled to said cold water inlet, a hot water poppet valve aperture adapted to receive a hot water poppet valve, and a cold water poppet valve aperture adapted to receive a cold water poppet valve;
a temperature control wheel in communication with said hot water poppet valve and said cold water poppet valve, and coupled to said temperature control knob;
and
a flow control stem having a first end coupled to said flow control knob, and a second end coupled to a seat bibb washer adapted to alternately engage a seat in a closed position and release from said seat in an open position;
said valve body having a flow sleeve coupled to said valve temperature regulator assembly housing and a valve body surrounding and in fluidic communication with said flow sleeve and said spout;
wherein rotation of said temperature control knob rotates said temperature control wheel to selectively permit movement of said hot water poppet valve and said cold water poppet valve between a closed position and an open position;
wherein in rotation of said flow control knob translates said flow control stem longitudinally to selectively move said seat bibb washer from said closed position to said open position.

A mixing hydrant comprising:

a head having a flow control knob, a temperature control knob, and a spout;
a valve body coupled to said head,
a valve temperature regulator assembly having a housing, a poppet valve body received in said housing, and a valve sealing surface;
said poppet valve body having a hot water inlet nipple coupled to a hot water inlet, a cold water inlet nipple coupled to a cold water inlet, a hot water poppet valve aperture adapted to receive a hot water poppet valve, and a cold water poppet valve aperture adapted to receive a cold water poppet valve;
a temperature control wheel having a cammed surface in communication with said hot water poppet valve and said cold water poppet valve, and coupled to said temperature control knob;
and
a flow control stem having a first end coupled to said flow control knob, and a second end coupled to a seat bibb washer adapted to alternately engage said valve sealing surface in a closed position and release from said valve sealing surface in an open position;
said valve body having a flow sleeve coupled to said housing of said valve temperature regulator assembly opposite said head and a valve body surrounding and in fluidic communication with said flow sleeve and said spout;
wherein rotation of said temperature control knob rotates said temperature control wheel to selectively allow movement of said hot water poppet valve and said cold water poppet valve between closed positions and open positions;
wherein in rotation of said flow control knob translates said flow control stem longitudinally to selectively move said seat bibb washer from said closed position in contact with said valve sealing surface to said open position away from said valve sealing surface.
