摘要： An improved method and apparatus for use with an underground tank of fire suppression fluid in which the fluid level within the tank can be visually determined quickly during pumping operations. Also, the fluid in the underground tank is protected from freezing by draining the fluid standing above the top of the tank. Protection against collapse or rapture of the underground tank is provided by a method of ventilating air into and out of the tank.

摘要： A dry (unpressurized) hydrant utilizes a hydrant pipe wherein a submerged end carrying a strainer assembly is placed at a predetermined depth within a body of water, such as a lake or a pond, with the unsubmerged end being located above ground adjacent the water surface. A check valve installed behind the underwater strainer allows the pipe to be filled with water delivered from a tank onboard a pumper truck. Flooding the pipe in this manner allows the pumper truck to then pump water from the lake or pond, through the hydrant, with little or no priming necessary so as to meet fire suppression demands. A vent valve located on the pumper intake connected to the unsubmerged end allows air to escape from the pipe during the filling process. In a further embodiment, a bypass system enables the strainer to be periodically back-flushed, without removal of the strainer, through the provision of a bypass check valve which opens in the reverse direction from the main check valve at a pressure greater than the normal filling pressure.
摘要翻译：干燥（非加压）消火栓采用消防龙头管，其中承载过滤器组件的浸没端放置在诸如湖泊或池塘的水体内的预定深度处，其中未浸没的端部位于水面附近。安装在水下过滤器后面的止回阀允许管道上装满从泵车上的罐中输送的水。以这种方式对管道进行喷射，使得泵车从湖泊或池塘通过消防栓泵送水，几乎不需要或不需要底漆，以满足灭火需求。位于连接到未浸泡端的泵送器上的排气阀允许空气在填充过程中从管道逸出。在另一个实施例中，旁路系统使得过滤器能够周期性地反冲洗，而不需要去除过滤器，通过设置旁路止回阀，该旁通止回阀在大于正常压力的压力下从主止回阀以相反方向打开填充压力。

摘要： An intake strainer for establishing a sufficient water supply to a suction hose. The intake strainer includes a triangular-shaped body having an elongated bottom, a screened intake, and foot members extending from the body for elevating the intake. The body also includes interior guide vanes angled from the intake towards a central opening of the body to form water-receiving channels. Optional low water-level control blades may also be used with the intake. Extending from the side opening of the body is an outlet member which serves to fluidly connect to a hose, such as a fire hose, or a threaded coupler which would in turn connect to a threaded part of the fire hose. The strainer may be attached to a support plate for being affixed to a supporting frame of the holding tank or alternately may be used in a skimmer assembly and/or be attached to a flotation member.
摘要翻译：用于为吸入软管建立足够的供水的进气过滤器。进气过滤器包括具有细长底部的三角形体，筛选的进气口和从主体延伸以升高进气口的脚部件。身体还包括从入口朝向身体的中心开口成角度的内部导向叶片，以形成受水通道。可选的低水位控制叶片也可与进气口一起使用。从主体的侧开口延伸的是用于流体地连接到诸如消防水带的软管或螺纹联接器的出口构件，螺纹联接器又将连接到消防水带的螺纹部分。过滤器可以附接到支撑板上以固定到保持箱的支撑框架，或者可替代地可以用于撇渣器组件和/或附接到浮选构件。

摘要： A dry (unpressurized) hydrant utilizes a hydrant pipe formed from PVC. One end engages a sliding swivel mount attached to a post with the other end of the pipe being free to swing and to be placed within a nearby body of water. The free end may include a strainer assembly, also formed of a PVC material. The strainer end may be placed at a predetermined depth within a body of water, such as a lake, pond or the like, by means of a second support located proximate the body of water. Alternatively, the strainer end of the hydrant pipe may be provided with a buoyant float to maintain the level of the strainer end of the hydrant pipe just below the water surface. In another embodiment, the strainer end of the hydrant pipe is provided with a rotating wheel assembly which enables the strainer end of the hydrant pipe to be rolled into position beneath the surface of the body of water. The dry hydrant is formed from inexpensive and lightweight materials and can be stored dry when not in use.
