    摘要: A hydrant valve assembly including a spool member having at least one spool seal which is at times under extremely high pressure tending to cause the seal to be displaced from an associated recess, the spool member forming venting passages in the seal recess to alleviate seal pressure, the invention also including a new wet pipe design and a new collar design.

    摘要: A nonfreezing, nonpolluting hydrant construction. The hydrant includes an above-ground discharge head, a main valve body disposed below frost line, and a stand pipe interconnecting the two. A flow tube is mounted inside the stand pipe. The upper end of the flow tube is connected to a hydrant opening and closing actuator which reciprocates the flow tube. The lower end of the flow tube carries an ejector assembly incorporating a venturi. In its lower position the ejector engages a seat to close off an inlet line. When the hydrant is shut off, water in the upper portion of the hydrant drains to the valve body and lower portion of the stand pipe below frost line. On subsequent opening of the hydrant, this water is ejected through the venturi. The hydrant also includes a float and check valve assembly to prevent filling of the stand pipe in the event the discharge line is blocked while the hydrant is open. A modified unit in which the hydrant mechanism is embodied in a drinking fountain is also disclosed.

    摘要翻译: 非冻结,无污染的消防栓结构。 消防栓包括一个地上排放头,一个设置在霜冻线之下的主阀体和一个连接两者的立管。 流管安装在立管内。 流管的上端连接到使流管往复运动的消火栓打开和关闭致动器。 流管的下端装有一个装有文丘里管的喷射器组件。 在其较低的位置,喷射器接合座,以关闭入口线。 当消防栓被关闭时,消防栓上部的水会排出到阀体和立管下方的霜管下方。 在随后打开消防栓时,这些水通过文丘里管喷出。 消防栓还包括浮子和止回阀组件,以防止在消防栓打开时排放管路被堵塞的情况下填充立管。 还公开了一种在饮水机中体现消火栓机构的改进单元。
