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

　　熔斷器芯桿頂端尋常卡住閥軸(葉片軸)上的叉板，使閥門在于常開形態。當發生火災后，彈道內氣旋量度升到熔斷器易熔斷易熔片，即繃簧促進芯桿，脫開叉板，閥軸受扭力繃簧作用而轉動開放閥門。

　　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.

　　安裝正在地方空調機風道零碎中，任務原理是極易熔合金的量度掌握，使用重力作用和繃簧組織的作用開放閥門。當火警發生時，火苗入侵風道，低溫使閥門上的易熔合金熔解，或者使回憶合金發生形變使閥門主動開放，用來風道與防火分區貫穿的場合。

　　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.

　　尋常風量大小如需調節，可通過與閥軸(葉片軸)聯動的曲柄調節閥門開度，抵達要求時由蝶母流動其地位。曲柄與叉板接觸處制有環齒，防止滑行耦合后，閥門開度調定后以保持沒有變。

　　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、風道系統阻力平衡自動計算的執行過程基本延用常規設計的計算步驟，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.將各節點間的邏輯關系、管段的相關參數依次輸入并保存，然后根據技術要求初步選定各管段的假定風速

　　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.根據假定風速自動計算管段當量水力直徑及阻力損失

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

　　3.用節點逆尋法自動查找系統各環路的路徑及阻力損失，并確定系統不利環路

　　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.對非不利環路進行自動阻力平衡。

　　4. automatic balancing of the non adverse loop.
