系列008PCQT适用于室内设施，用于防止受到污染的水倒虹吸到饮用水的供应管道中。供水与空气的隔离是通过采用隔膜密封的方法实现的。这个功能有助于在开启或运行期间防止任何泄漏或溢出。
　　Series 008PCQT is designed for indoor point of use applications to prevent backsiphonage of contaminated water back into the potable water supply. Separation of the water supply from the air inlet is accomplished by means of a diaphragm seal. This feature protects against any spillage during start-up or operation.

安装
Installation

　　008PCQT适用于安装在使用点上。当工厂在安装机械或设备上的台面/装置时，008PCQT的临界水平不得低于地面以上25毫米的高度。如果是在现场安装，应用在常用的管道设施上，则008PCQT的临界水平至少要比地面高出150毫米。
　　The 008PCQT is designed to be installed at the point of use. When factory installed deck/machine mounted on machines or equipment, the critical level of the 008PCQT shall be not less than 1" (25mm) above the flood rim. If field applied for general plumbing applications, the critical level of the 008PCQT shall be a minimum of 6" above the flood rim.

规格说明
Specifications

　　正如计划书中所注明的，根据制造商的说明，应该安装一个防溢出真空断路阀(SVB)。这种阀门应该由一个模块式止回阀和浮子组装构成，采用工程热塑塑料制造，安装在青铜阀体内。弹簧材质应该是不锈钢。这种阀门应该配置一个模压隔膜，将空气进口与饮用水供水管道隔离开来，以防止泄漏或溢出。这种阀门应该是美国瓦茨调节阀公司系列008PCQT.
　　A spill-resistant vacuum breaker (SVB) shall be installed, in accordance with the manufacturer's instructions, as noted on the plans. The valve shall consist of a one piece modular check and float assembly made of engineered thermoplastic and housed in a bronze body. Springs shall be stainless steel. The valve shall be constructed with a molded diaphragm separating the air inlet from the potable water supply to prevent spillage. The valve shall be a Watts Regulator Company Series 008PCQT.
