型号85/90M的工作原理
HOW THE FIGURE 85/90M WORKS

　　正如右侧示意图所示，型号85或90M防冻洒水龙头上最靠近的部件(阀杆和阀瓣总成)，是通过顺时针方向旋转手柄来实现旋转关闭和逆时针方向旋转开启。
　　As shown on the schematic drawing on the right, the closing member (stem and disc assembly) of the Figure 85 or 90M Frostproof Sillcock operates by turning the handle in a clockwise manner to close and counter-clockwise to open.
　　阀门的阀座位于手柄对面的另一端。阀门结构使得阀座区域安全位于房间保温外墙的内侧。这可防止阀座区域不会暴露在冰冻温度中。根据安装地区的不同，可提供的阀杆长度也有所不同，以适应不同的墙壁厚度。阀门的“轮廓”尺寸(参阅A尺寸)与安装厚度有关，其尺寸是从防冻洒水龙头法兰到阀门阀座，可提供的长度是101mm, 152mm, 203mm, 254mm, 305mm和356mm.
　　The valve’s seat is at the opposite end from the handle. The valve is designed so that the seat area is situated safely behind the insulation of the home’s exterior wall. This is to prevent the seat area from being exposed to freezing temperatures. Depending on the region of installation, the stem length is available in varying dimensions to accommodate the various insulation thicknesses behind the wall. The valve’s “rough-in” dimension (see “A” dimension) pertains to the thickness of insulation and is measured from the frostproof sillcock’s flange to the valve seat and is available in lengths 4", 6", 8", 10", 12" and 14".
　　型号85和90M结构上配置一个一体式防回流装置，用以防止潜在的反虹吸现象。如果不加以防止，可能会汇入安全的饮用水中，并进入房间内，导致疾病或死亡。
　　The Figure 85 and 90M are designed to employ an integral back-flow prevention device to prevent potential back-siphonage. This backsiphonage, if unchecked, could compromise the safe potable water supply to the home, resulting in sickness or death.
　　独立的检测机构，美国卫生工程协会和加拿大标准协会，对于阀门的主要性能和预防性能进行检测认证。
　　The independent testing bodies, American Society of Sanitary Engineering and Canadian Standards Association, have validated the valve’s primary and preventative functions.

延长使用寿命的小技巧
TIPS FOR LONG LIFE

1. 应该小心移动软管，使其在拉拔时不会产生异常的张力。
   The hose should be carefully moved about, so as not to cause abnormal tension via pulling and/or jerking.
2. 如果型号85和90M的软管位于冰冻气候中，阀门的自排泄功能将会保护洒水龙头不会冻坏，如果：1)洒水龙头出口没有连接软管；或2)整个软管长度都位于防冻洒水龙头的连接点下方。
   If the hose is left on the Figure 85 and 90M in freezing weather, the valve’s self-draining feature will protect the sillcock from freeze damage if: 1) the nozzle is not left affixed to the hose; and 2) the entire hose length is on a plane lower than the fixed position of the frostproof sillcock.
3. 型号85和90M能够承受冰冻气候并且在冰冻气候下正常运行的主要原因是由于关闭部件(阀座阀瓣)是位于有暖气的建筑物内部。如果暖气暂时关闭一段可能发生冰冻的时间，则所有水管都应该排泄干净。
   The key to the Figure 85 and 90M being able to withstand and operate in freezing weather is that the closing member (seat disc) is inside the heated building. If the heat is temporarily shut down for a length of time that would allow freezing to take place, all water lines should be drained.
4. 型号85和90M在洒水龙头的进口处关闭。您会注意到关闭后会滴水几秒钟。至少要等10秒。如果滴水仍然继续，则稍微更紧的关闭阀门直到滴漏停止。过紧的关闭力可能会损坏阀座区域的部件。
   The figure 85 and 90M closes at the inlet of the sillcock. You will notice that it will drip for a few seconds after being closed. Wait at least 10 seconds. If dripping continues, close the valve more tightly in small increments until dripping ceases. Excessive closing force can damage components in the seating area.

安装指南
INSTALLATION INSTRUCTIONS

1. 在适当的位置钻29mm直径的穿墙孔，从墙外插入型号85或90M防冻洒水龙头。要记住保持所需的一定斜度，以帮助排泄和防止由于冰冻而损坏洒水龙头(参阅上列示意图)。
   Bore a 1¹/₈" diameter hole through the wall in the desired position and insert the Figure 85 and 90M from the outside. Keep in mind a downward slope is required to aid draining and prevent damage to the sillcock due to freezing (see schematic drawing above).
2. 使软管出水口位于朝下位置。
   Position the spout (hose outlet) in a downward position.
3. 在连接到供水管道后，要确保洒水龙头法兰配置有适当的螺丝或紧固件。对于倒齿滑动安装，要配置一个侧面楔形板，美化外观。
   After the connection has been made to the water supply, secure the sillcock flange with suitable screws or fasteners. For installations on lapped-type siding, a siding wedge is supplied to give a finished look.
4. 如果是焊接连接，则在加热之前要把手轮旋转到全开的位置。*
   If the connection is to be made by soldering, turn the handwheel to the fully open position before applying heat.*

　　* 警告：在焊接时，要避免过热 - 过热会导致阀座区域受到内部损坏。
　　* Warning: Avoid overheating when soldering — it could cause internal damage to seat area.
