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

　　熔斷器芯桿頂端尋?？ㄗ￠y軸(葉片軸)上的叉板，使閥門(mén)在于常開(kāi)形態(tài)。當(dāng)發(fā)生火災(zāi)后，彈道內(nèi)氣旋量度升到熔斷器易熔斷易熔片，即繃簧促進(jìn)芯桿，脫開(kāi)叉板，閥軸受扭力繃簧作用而轉(zhuǎn)動(dòng)開(kāi)放閥門(mén)。

　　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(diào)機(jī)風(fēng)道零碎中，任務(wù)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(kāi)放閥門(mén)。當(dāng)火警發(fā)生時(shí)，火苗入侵風(fēng)道，低溫使閥門(mén)上的易熔合金熔解，或者使回憶合金發(fā)生形變使閥門(mén)主動(dòng)開(kāi)放，用來(lái)風(fēng)道與防火分區(qū)貫穿的場(chǎng)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(fēng)量大小如需調(diào)節(jié)，可通過(guò)與閥軸(葉片軸)聯(lián)動(dòng)的曲柄調(diào)節(jié)閥門(mén)開(kāi)度，抵達(dá)要求時(shí)由蝶母流動(dòng)其地位。曲柄與叉板接觸處制有環(huán)齒，防止滑行耦合后，閥門(mén)開(kāi)度調(diào)定后以保持沒(méi)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(fēng)道系統(tǒng)阻力平衡自動(dòng)計(jì)算的執(zhí)行過(guò)程基本延用常規(guī)設(shè)計(jì)的計(jì)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(jié)點(diǎn)間的邏輯關(guān)系、管段的相關(guān)參數(shù)依次輸入并保存，然后根據(jù)技術(shù)要求初步選定各管段的假定風(fēng)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(jù)假定風(fēng)速自動(dòng)計(jì)算管段當(dāng)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(jié)點(diǎn)逆尋法自動(dòng)查找系統(tǒng)各環(huán)路的路徑及阻力損失，并確定系統(tǒng)不利環(huán)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(duì)非不利環(huán)路進(jìn)行自動(dòng)阻力平衡。

　　4. automatic balancing of the non adverse loop.
