Valve can not be ignored in the construction sector selection In building the pipeline system, the valve control fluid plays a role. As the structure and the different materials, so the valve will produce different. In order to ensure the pipeline system to achieve the highest efficiency, lowest cost and longest life, the correct valve selection is critical. Valve has four main functions: start and stop media flow; regulating media flow; to prevent backflow or back and adjust or discharge of fluid pressure. The choice of building the pipeline system can vary with temperature, media type, temperature and other factors to consider. For example, for high-rise buildings in the fire hydrant valve control signal should be used on the valve, which is related to the possibility of a fire hydrant system when a key is being used, the fire hydrant system control valves are located to the signal valve, and valve doors open in the fire control center, in order to facilitate the management of inspection, although the cost has increased, however, it is for the fire hydrant system, or the ratio of the investment is minimal and it can make the fire hydrant system security is greatly increased, which point is still worth the investment. Building in the piping system valve type selection must be based on the characteristics of the building to be selected, if the valve does not meet the building's design features, so many potential pitfalls will continue the

在建筑物管道系统中，阀门起着控制流体的作用。由于结构和材质的不同，因此制造出的阀门也就各不相同。为了保证管道系统能够实现最高的效率，最低的成本和最长的使用寿命，阀门的正确选型至关重要。　阀门具有四种主要功能：启动和阻止介质流动；调节介质流量；阻止倒流或回流和调节或泄放流体压力。建筑物管道系统的选择可以根据温度、介质类型、温度等因素来考虑。例如，对于高层建筑物中的消防栓控制阀门就应该采用信号阀，这是关系到消火栓系统能否在火灾时被合理使用的关键，将消火栓系统的控制阀均设成信号阀，并且阀门开启状态能在消防控制中心显示，以便于管理人员检验，虽然造价有所提高，但是，它对于整个消火栓系统的投资之比还是微乎其微，并且它可以使整个消火栓系统的安全性大大提高，这点投资还是值得的。建筑物管道系统中的阀门类型选择必须根据建筑物的特性来加以选择，如果使用的阀门不符合该建筑的设计特点，那么很多潜在的隐患将会不断出
