摘要： A method and an apparatus to aid in the prevention of pipe freezing. This method utilizes fluid in motion to help pipes resist freezing. When initiated by the control circuit, fluid flows through the pipes to prevent freezing. The control system utilizes either a fixed duty cycle, a variable duty cycle, a duty cycle which can be selected or a temperature sensor. Other apparatus of this sort use the heat produced by electrical current to heat a pipe to prevent freezing. The method and apparatus described here utilizes fluid in motion to accomplish a similar task. This method is particularly suited for hot water circulating types of systems.

摘要： A freeze prevention device for water systems includes a relief valve and an actuator having an elongated chamber which contains water and segments that sequentially sense the incremental expansion caused by ice formation therebetween. The segments are axially aligned within the chamber. The segments may be balls, truncated pyramids, and the like that have a sealing portion and an axial portion with a foot which is adapted to engage an adjusting screw or a wear compensating spring at the bottom of the chamber or the top of the adjacent segment. An actuation linkage transmits linear meovement of one or more segments to a poppet in a valve seat, thereby opening a valve port connecting water, from a water supply system or a tank, to a discharge port, whereby water may be bled from the water system to prevent freezing thereof, or steam from a steam system for admission to tracer lines.

摘要： A freeze preventing valve which comprises a valve body longitudinally provided with an inserting hole at the upper part thereof in a hollow valve housing connected to a steam feed pipe, a valve element having a shaft disposed movably through the inserting hole of the valve body to be able to open an exhaust port at the lower end of the housing and to be vertically guided through the inserting hole of the housing. A collar is secured at an intermediate position on the shaft and a spring of shape memory alloy is interposed between the upper surface of a valve seat of the valve housing and the lower surface of the collar for urging the valve element to close the valve, by moving the valve element upwardly. A bias spring is mounted between the lower surface of the upper part of the valve body and the upper surface of the collar for urging the valve element to open the valve. Thus, the valve element of the freeze preventing valve is effectively operated by the both springs via the collar mounted on the shaft of the valve element, disposed in the valve body.

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： A freeze protection valve can be reset under cold ambient conditions without the need for artificial heating of the valve's temperature sensor. An auxiliary latch is used to hold the valve element closed. The auxiliary latch is automatically released as the primary latching mechanism of the valve becomes operative upon an increase in temperature of the liquid system served by the valve. Release of the auxiliary latch is effected by virtue of a small downward movement of the valve stem resulting from a camming action inherent in the operation of the valve's primary latch.In one version of the valve, a simple, drop-away key temporarily holds the valve stem down until the primary latch becomes operative. In another version, the valve stem is reset remotely through a bowden wire, and the resetting mechanism automatically engages an auxiliary latch.
摘要翻译：冷冻保护阀可在寒冷环境条件下复位，无需人工加热阀门温度传感器。辅助闩锁用于将阀门元件关闭。当阀门的主要锁定机构随着阀门所服务的液体系统的温度升高而变得可操作时，辅助闩锁自动释放。辅助闩锁的释放是由于阀杆的小的向下运动而产生的，这是由于阀的主闩锁的操作固有的凸轮作用引起的。在一个版本的阀门中，一个简单的掉落钥匙将阀杆暂时保持下来，直到主闩锁变得可操作。在另一个版本中，阀杆通过弓形导线远程复位，复位机构自动接合辅助闩锁。
