摘要： A domestic water distribution system that continuously delivers heated water to one or more hot water faucets. The system utilizes a convective return loop from the desired faucets, which is regulated by a flow control device. The control device is specifically designed to allow unhindered flow during circulation without allowing reverse flow when a faucet is opened. The flow control device has an easily accessible handwheel adjustment that is used to select the three modes of operation and the flow rate. These modes are called: HELD-ON, HELD-OFF, and NORMAL-OPERATION. With the first two modes being used to fill and flush the system as is necessary with new installation and recreation vehicles. Also, a lighter-than-water checking element is used, which allows the system to function in single-level plumbing installations without the need for inclined supply and return routing. The circulation is further assured by having the plumbing return and cold water supply connected to the base of the water heater, which creates a flushing action of sediment that accumulates inside and since plumbing insulation is not restricted, heat loss is limited.
摘要翻译：一种将一个或多个热水龙头连续输送加热水的家用配水系统。该系统利用来自所需水龙头的对流返回回路，该回路由流量控制装置调节。控制装置专门设计成允许循环期间不受阻的流动，而当水龙头打开时不允许逆流。流量控制装置具有容易接近的手轮调节，用于选择三种操作模式和流量。这些模式被称为：HELD-ON，HELD-OFF和NORMAL-OPERATION。使用前两种模式用于填充和冲洗系统，如新安装和娱乐车辆所必需的。此外，使用比水更轻的检查元件，其允许系统在单级管道安装中运行，而不需要倾斜的供应和返回路由。通过将管路返回和冷水供应连接到热水器的底部进一步确保循环，这产生了内部积聚的沉积物的冲洗作用，并且由于管道绝缘不受限制，热损失受到限制。

摘要： A cylindrical heat-generating member is disposed in a valve casing including a valve seat in a flow path connecting main ports, a valve member for opening and closing the valve seat, and a rod connecting the valve member and a piston. A first heater is mounted in the heat-generating member. The heat-generating member and a heat receiving member of the valve member are connected to each other by a heat-transfer member for expansion and contraction. As a result, the valve member is constantly heated through the heat-transfer member irrespective of its open/closed position. When the valve member is open, the heat receiving member comes in contact with the heat-generating member and the valve member is directly heated.

摘要： Methods and devices for the management of fluid flow within nanoscale analytical systems, comprising a freeze thaw valve having differing geomentries to constrict a frozen plug within the freeze thaw segment. The freeze thaw valve is directed to use in high-pressure analytical systems. The geometry of an inner diameter of a channel or tube within a freeze thaw segment is configured to cause constriction of a freeze plug when axial force is applied. The constriction is used in the flow-path of a freeze thaw valve to prevent movement of the frozen plug at high pressures to avoid valve leakage.

摘要： A counter-flow prevention valve is disposed within a body of a pilot-type channel valve. While electrical power is applied to a solenoid coil and the pilot-type channel valve is opened, i.e., while a gas is flowing through the counter-flow prevention valve and the gas is expanding, heat generated by the application of electrical power to the solenoid coil is conducted via the body and is effectively transferred to the counter-flow prevention valve. Therefore, even if the gas contains water vapor and even if this gas is cooled due to significant expansion, the water vapor can be prevented from freezing within the counter-flow prevention valve. Moreover, the volume of the pipe between the pilot-type channel valve and the counter-flow prevention valve is small, thereby resulting in a fast rise in pressure within the pipe and a quick opening of the counter-flow prevention valve, which provides an excellent valve-opening response.

摘要： A thermostatically controlled bypass valve for bypassing water away from a hot water valve until the water temperature reaches a desired level at a fixture in use for home or industrial applications. The bypass valve has a valve body with a thermally sensitive actuator disposed between the hot water inlet and discharge ports and the cold water inlet and discharge ports that is thermally responsive to the temperature of the water. A bias spring pushes against the piston on the thermal actuator to close the actuator and open a passage between the cold and hot water sides when water needs to be bypassed. When the water from the hot water heater reaches the desired temperature level at the bypass valve, the bypass valve closes and hot water is made available to the hot water side of the fixture. Until then, the thermal actuator remains open and cold or tepid water is allowed to bypass the hot water side of the fixture. Flexible hoses attach the inlet and discharge ports on the hot and cold water sides to the hot and cold water supply systems and the hot and cold water valves on the fixture. A check valve can be placed on the cold water side to prevent the flow of cold water through the bypass valve when only the hot water side is flowing. The bypass valve can used as part of a water circulating system having a pump placed in the hot water piping system that can also include a pump check valve for bypassing high flows around the pump and a flow rate switch for turning off the pump. The bypass valve can be incorporate integrally into the fixture.
