的TMV与军团之间的9 Relationsships：

军团菌是负责军团病，下呼吸道的急性细菌感染的细菌。 这种细菌最初是在1977年确定的疾病控制中心为肺炎的爆发造成34人死亡，在1976年的美国退伍军人大会在费城的原因。 庞蒂亚克发烧是不太严重的，非肺炎，流感样是与相关联，并且可能是由军团菌引起的疾病。 军团菌是一种相当常见的水的细菌和已发现在许多表面水源，例如广泛存在; 湖泊，河流，小溪和池塘。 它也可以在地下水源和一些土壤中发现。 在这些天然来源中发现的水平它通常不会对公众健康构成威胁。 当细菌进入生活用水体系

它可以找到温暖的水温（40-46Celsius度），积水区（储罐和死胡同管道腿）和充足的食物来源（泥沙，水垢，沉积物和生物膜）的理想主机环境。 在这些条件下军团能迅速定植，形成较高的浓度，可以造成退伍军人病症的公共卫生威胁。

有控制军团菌定植的方法很多。 然而，一个广泛接受的和优选的方法是不断维持热水系统储存温度等于或高于60℃。 遗憾的是，所需的升高的温度下，以减少的生长和杀死军团菌已引起严重的热冲击和烫伤的可能性。

4. What is the thermostatic mixing valve?

A Thermostatic Mixing Valve is a valve that blends hot water (stored at temperatures high enough to kill bacteria) with cold water to ensure constant, safe outlet temperatures preventing scalding.

They shut-off rapidly in the event of a hot or cold supply failure to prevent scalding or thermal shock.

TMVs accurately control water temperatures for bathing, showering and hand-washing. They maintain pre-set temperatures - even if water pressure varies when other appliances are used. TMVs can be fitted under baths and basins, be part of shower fittings, or as a feature of exposed hot and cold water mixers.

5. Usage of TMVs

Point of use mixing for wash hand basins, bidets, baths and showers in hospitals, schools, sport and leisure facilities, prisons and other public buildings.

6. Installation Precaution:

a. All installations should be carried out by a Licensed Professional.

b. Install in accordance with markings on valve body. i. e. hot water inlet-marked H, cold water inlet-marked C.

c. After temperature setting, if inlets temperature or pressure fluctuates, outlet temperature variation is within +/ -2 C.

d. The external check valves at inlets prevent cross-flow of hot&cold water when inlets pressure is not the same.

e. If the ratio between two inlets is too large, one flow-limiting valve should be fixed at the side of higher pressure.

f. Prior to installation, provisions should be made to flush the piping of any debris or other foreign materials to ensure proper system operation.

7. How They Work?

Upon use of tempered water, a thermostat in the mixing chamber of the valve senses the outlet temperature. The thermostat automatically positions a seat assembly which controls the flow of hot and cold water supplied to the mixing chamber. If the mixed outlet temperature increases, the thermostat will expand moving the seat assembly to allow the cold water inlet port to open more fully and at the same time restricting the hot water inlet port. Conversely, if the mixed outlet temperature decreases, the thermostat will contract moving the seat assembly to allow the hot water inlet port to open more fully and at the same time restricting the cold water inlet port. In both cases the mixed outlet water temperature is automatically and continually maintained at the preset temperature within the tolerances of the valve. In the event of a cold or hot water supply failure, the seat assembly moves to an extreme position shutting off the hot or cold inlet water port. A mechanical adjustment permits selection of the desired outlet water temperature within range of the valve.

b. Install in accordance with markings on valve body. i. e. hot water inlet-marked H, cold water inlet-marked C

c. After temperature setting, if inlets temperature or pressure fluctuates, outlet temperature variation is within +/ -2 C.

9. Relationsships between TMVs and Legionella:

Legionella is the bacteria responsible for Legionnaires Disease, an acute bacterial infection of the lower respiratory tract. This bacterium was first identified in 1977 by the Centers for Disease Control as the cause of an outbreak of pneumonia that caused 34 deaths at a 1976 American Legion Convention in Philadelphia. Pontiac Fever is a less severe, non-pneumonia, flu-like disease that is associated with and likely caused by Legionella bacteria. Legionella is a fairly common water bacteria and has been found to exist widely in many surface water sources such as; lakes, rivers, streams and ponds. It can also be found in ground water sources and some soils. At the levels found in these naturally occurring sources it typically does not pose a threat to public health. When the bacterium enters a domestic water system

It can find an ideal host environment of warm water temperatures (40-46Celsius degree) , stagnant water areas (storage tanks and dead-end piping legs) and ample food sources (sediment, scale, deposits and biofilm) . Under these conditions Legionella can rapidly colonize, forming higher concentrations that can pose the public health threat of Legionnaires Disease.

There are many methods of controlling colonization of Legionella bacteria. However, a widely accepted and preferred method is to maintain the hot water system storage temperature continually at or above 60C. Unfortunately, the elevated temperature necessary to minimize the growth of and kill Legionella bacteria has the potential to cause serious thermal shock and scalding injuries.
