摘要： An automatic draining back flow prevention apparatus comprises tubular body structure having main passage structure between flow entrance and exit ports; the body structure having first and second side ports communicating with the passage structure; first and second diaphragms carried by the body structure to be exposed to flow in the passage structure; a stopper in the passage structure cooperating with the first diaphragm to pass forward fluid flow while a first diaphragm flexes to block exit flow of fluid through the first side ports, and to block back flow of fluid through the main passage structure when the first diaphragm moves to unblock exit flow of fluid through the first side port; the second diaphragm movable to allow in-flow of air through the second side port when the stopper and first diaphragm block back flow of fluid through the main passage structure.

摘要： Fire hydrant drain holes are unplugged from within a hydrant barrel by removing the bonnet and valve gear from the top of the barrel and using a specialized drilling tool which is inserted into the barrel to fit on the valve seat. The tool has a drill bit which aligns with the drain hole and a flexible drive wire for the drill bit which extends to the top of the barrel for operation from above the hydrant.

摘要： A water hydrant is provided with a number of valves operable to eliminate freezing problems and to prevent backflow into potable water, thereby precluding the danger of contamination. Water and air valves operate in conjunction such that trapping of water in the hydrant is averted by the admission of air after each closing of the water valve. By a somewhat different arrangement in outlet spout valving, air is also admitted to the spout after each closing of the water valve or other reduction in water pressure, the spout valving having the additional feature of blocking backflow, all of which meets the anti-contamination requirements of the hydrant.
摘要翻译：消防栓设有多个可操作的阀，可以消除冷冻问题，防止回流进入饮用水，从而排除污染的危险。水和空气阀联合操作，使得在每个关闭水阀之后，通过吸入空气来避免消防栓中的水的捕获。通过在出口喷口阀门中有一些不同的布置，每次关闭水阀之后，空气也被允许进入喷口或其他水压降低，喷口阀具有阻止回流的附加特征，所有这些都符合抗污染消防栓的要求。

摘要： A yard hydrant includes an improved valve assembly connecting the hydrant standpipe at a point below the frost line to a source of water under pressure. A hollow and generally cylindrical housing of such assembly is provided with a bore concentrically reduced relative to the diameter of the housing and having an upper plane spaced inwardly from the upper end of the housing to receive a rod mounted and handle operated valve. The bore terminates at its lower end in a valve seat defining a further concentrically reduced access opening to the water supply. In spaced concentric relationship about the bore are a plurality of water passageways each in communication with said bore and each extending from the upper plane thereof for communication with the standpipe to a point spaced above the valve seat so that the bore is full circle only intermediate the valve seat and the lower limits of the passageways. A drain hole is provided through the housing to the bore near the upper plane thereof. The seated valve shuts off the water supply and exposes the drain hole for water drainage to the surrounding ground from the standpipe and in the opening of the valve, water cannot flow to the standpipe until the valve has not only moved off of the valve seat but has moved beyond the full circle bore area to expose the lower end of the water passageways to communication with the source of water and at which time, the valve has closed the drain hole to prevent escape of incoming water at that point so that all of such water flows directly to the standpipe and nozzle. The design of the housing makes possible the use of plastic materials for economy in manufacture and efficiency in operation.
摘要翻译：一个码头消防栓包括一个改进的阀门组件，该组件将霜冻管线下方的消火栓立管连接到压力下的水源。这种组件的中空的和大致圆柱形的壳体设置有相对于壳体的直径同心地减小的孔，并且具有从壳体的上端向内间隔开的上平面，以容纳杆安装和手柄操作的阀。孔在其下端终止在阀座中，限定了进一步同心减小的进水开口。围绕孔的间隔的同心关系是多个水通道，每个水通道与所述孔连通，并且每个水通道从其上平面延伸以与立管连通到在阀座上方间隔开的点，使得孔是完整的圆阀座和通道的下限。排水孔通过壳体设置到靠近其上平面的孔。座阀关闭供水装置，将排水孔从立管和阀门的开口处暴露在周围地面，水不能流到立管，直到阀门不仅从阀座离开，而且已经移动到全圆孔区域以露出水通道的下端以与水源连通，此时阀已经关闭排水孔，以防止在那一点进入的水的逸出，使得所有这些水直接流到立管和喷嘴。房屋的设计使得塑料材料的使用成为制造经济和运行效率的可能。

摘要： A valve is located below the frost line in the water supply line for a drinking fountain or the like. When the valve is opened, a piston is raised by the water pressure, compressing a spring. When the valve is closed, the spring retracts the piston, sucking the water in the line down below the frost line. Water is retained within the valve and not drained into the surrounding earth. Hence, danger of pollution is reduced.

摘要： A hydrant for controlling the flow of water from an underground supply includes a casing connected at its lower end to the supply and its upper end to a nozzle for delivery of water from the casing. The flow of water from the supply to the casing is controlled by a main valve operated by a handle on the hydrant casing. An ejector purge apparatus drains the casing after the flow of water through the casing has been terminated by the main valve in order to prevent frost damage. The ejector purge apparatus includes a purge valve controlling flow from the supply through a conduit to a location outside of the hydrant casing. The conduit includes a flow constricting element and a port adjacent the flow constricting element that is in fluid communication with the casing. Flow through the purge valve and the flow constricting element results in venturi evacuation of the water within the casing. The purge valve is maintained in an open position for a limited time by a motion dampening dash pot after closure of the main valve to allow complete evacuation.

摘要： A fluid connector apparatus or hydrant including an insulated casing enclosing a valve control element to supply water to a utilization station. A heating element is positioned within the fluid connector apparatus to prevent freezing of liquid therein. A fluid removal line is provided to remove accumulated water from within casing as required. The valve control element, the heating element and, in some applications, the fluid removal line are inserted in the casing in a manner facilitating ease of withdrawal of the elements for maintenance, servicing and replacement of the internal parts of the connector unit as required.
