摘要： A drain valve to drain water from a dry barrel hydrant includes a drain valve body fixed to a main valve assembly of the hydrant, and a hollow drain hole sleeve positioned in a drain hole of an elbow of the hydrant. The drain valve body includes a drain valve facing configured to align with the drain hole of the elbow as a result of the main valve assembly being in an open position, and to not align with the drain hole of the elbow as a result of the main valve assembly being in a closed position. In another embodiment, an elbow of a fire hydrant includes a hollow body, an upper end defining a drain hole to allow water to drain out, and a hollow drain hole sleeve in the drain hole.

摘要： A sanitary hydrant comprises an isolated reservoir that can be positioned below a freeze level at the location of installation. A piston within the isolated reservoir is operable to expel, during a downward stroke, stored fluid from the reservoir before actuating a valve that allows fluid to flow from a fluid supply source through the hydrant. On an upward stroke, the piston releases the valve and generates a negative pressure within the reservoir that draws fluid from within the hydrant into the reservoir.

摘要： Integrated flow control backflow preventer valve (“IFCBPV”) for new and existing wet- and dry-barrel fire hydrants, with barrel drain assemblies for dry-barrel hydrants, and hydrants equipped with such IFCBPVs, are presented. An exemplary IFCBPV can have a retaining screen comprising equidistant concave radial spokes intersecting at a central ring structure, a freely suspended check ball, and a lower ball seat with a seal. The upper surface of the retaining screen can be affixed to the hydrant's axial shaft, and can thus be used to open and close the hydrant via the ball. Alternatively, the retaining screen can be fixed and the axial shaft provided with a cup on its bottom that mates with the freely suspended ball that is caged between the retaining screen and the ball seat. An exemplary barrel drain assembly can comprise a spring-loaded piston, or alternatively, a check ball design as in the main barrel.

摘要： An anti-freeze faucet structure contains: an outer pipe, an inner pipe, a control valve, a resilient element, a unidirectional sealing gasket, and a controlling assembly. The outer pipe includes an inlet, an outlet, an opening, an intake valve, and a channel, wherein the channel has plural inner threads. The inner pipe includes a connecting segment and a fitting segment opposite to the connecting segment, the fitting segment has a peripheral protrusion, and the peripheral protrusion has a plurality of outer threads screwing with the plural inner threads of the outer pipe. The control valve movably is fitted on the fitting segment to abut against and close the inlet; the resilient element is fixed in the inner pipe to push against the control valve; the unidirectional sealing gasket is fitted onto the inner pipe; and the controlling assembly is disposed on the opening of the outer pipe.

摘要： A hydrant main valve includes a main seal elastically deformable between a first state and a second state, such that a main valve assembly may be inserted into a main valve elbow without removable valve seats. A main valve assembly rotation lock engages a rotation block inside the elbow preventing rotation of the main valve assembly. A rotating operating stem extension moves a main valve bottom plate relative to a drain valve body, causing main valve seal elastic deformation.

摘要： A method of draining a standpipe includes moving a valve control device toward a closed position sufficient to uncover at least one drain hole before the valve control device achieves a fully closed position, the at least one drain hole being disposed in a slot of a saturation ring and draining a contents of the standpipe through a drain route to an external portion of the standpipe, the drain route is defined by the drain hole in the valve seat ring, drain ports in the drain ring, outlet notches and a drain channel in the saturation ring. The drain hole is radially offset from each of the drain ports in the drain ring and each of the drain ports are radially offset from each of the outlet notches in the saturation ring. A valve control device is also disclosed.
