　　I. the operating principle of the fireproof valve in the ventilation and smoke exhausting equipment

　　熔断器芯杆顶端寻常卡住阀轴(叶片轴)上的叉板，使阀门在于常开形态。当发生火灾后，弹道内气旋量度升到熔断器易熔断易熔片，即绷簧促进芯杆，脱开叉板，阀轴受扭力绷簧作用而转动开放阀门。

　　The end of the fuse core rod is usually stuck on the fork plate of the valve shaft (blade shaft) so that the valve is in normally open form. When the fire occurs after the cyclone in ballistic rise to measure fuse easy fuse fusible film, which promote the core rod and spring, when the valve plate, shaft torsion spring and rotating the valve open.

　　安装正在地方空调机风道零碎中，任务原理是极易熔合金的量度掌握，使用重力作用和绷簧组织的作用开放阀门。当火警发生时，火苗入侵风道，低温使阀门上的易熔合金熔解，或者使回忆合金发生形变使阀门主动开放，用来风道与防火分区贯穿的场合。

　　Install air duct is local air conditioning system, task principle is a measure of the fusible alloy pole master, open valve using gravity and spring organization. When the fire broke out, the flames of intrusion duct, low temperature fusible alloy melting on the valve, or the memory alloy is deformed so that the valve open, to the air duct and the fire district through occasions.

　　寻常风量大小如需调节，可通过与阀轴(叶片轴)联动的曲柄调节阀门开度，抵达要求时由蝶母流动其地位。曲柄与叉板接触处制有环齿，防止滑行耦合后，阀门开度调定后以保持没有变。

　　Ordinary air volume, such as the need to adjust, can be connected with the valve shaft (blade axis) crank to adjust the valve opening, arrived at the request by the butterfly mother flow its position. The crank is connected with the fork plate to prevent the sliding coupling. After the valve is opened, the valve is opened and adjusted to remain unchanged.

　　二、风道系统阻力平衡自动计算的执行过程基本延用常规设计的计算步骤，主要如下：

　　Two, air duct system resistance balance automatic calculation of the basic implementation process using conventional design calculation steps are as follows:

　　1.将各节点间的逻辑关系、管段的相关参数依次输入并保存，然后根据技术要求初步选定各管段的假定风速

　　1., the logical relation among nodes and the related parameters of pipe section are input and saved in sequence. Then, the assumed wind speed of each pipe section is selected according to technical requirements

　　2.根据假定风速自动计算管段当量水力直径及阻力损失

　　2. calculate the equivalent hydraulic diameter and resistance loss of the pipe section automatically according to the assumed wind speed

　　3.用节点逆寻法自动查找系统各环路的路径及阻力损失，并确定系统不利环路

　　3., the method of node inverse searching is used to find the path and resistance loss of each loop, and the worst loop of the system is determined

　　4.对非不利环路进行自动阻力平衡。

　　4. automatic balancing of the non adverse loop.
