First, smoke smoke damper strong air tightness, mainly reflected in the following four aspects:

　　1、執行機構驅動靈活。反饋、聯鎖信號準確。

　　1, actuators flexible. The feedback and interlocking signals are accurate.

　　2、漏風量低，氣密性能好。

　　2 、 the air leakage is low, and the air tightness is good.

　　3、電動開啟消耗電流小。

　　3 、 electric opening consumes little current.

　　4、防腐性能強，使用壽命長。

　　4, corrosion resistance, long service life.

　　二、在裝修排煙防火閥時可以參照這些要點進行檢查，可以減少后期的損害，主要有以下五點：

　　Two, in the decoration smoke smoke fire valve can refer to these points for inspection, can reduce the damage later, mainly has the following five points:

　　1、排煙防火閥的熔斷片應裝在朝向火災危險性較大的一側。

　　1. The fuse shall be installed on the side of the fire danger.

　　2、排煙防火閥可與通風機、排煙風機聯鎖，閥門的操作機構一側應有不小于200mm的凈空間以利檢修。

　　2, smoke fire dampers can be ventilation, smoke exhaust fan interlock, the valve side of the operating mechanism should be less than 200mm of the net space, in order to facilitate maintenance.

　　3、排煙防火閥應單獨設支吊架，以防止發生火災時管道變形影響其性能。

　　3 smoke exhaust fire valve shall be provided with separate hangers to prevent pipe deformation during fire and affect its performance.

　　4、安裝排煙防火閥閥門前必須檢查閥門的操作機構是否完好，動作是否靈活有效。

　　4, the installation of smoke fire valve, valve must check whether the operation of the valve is intact, the action is flexible and effective.

　　5、排煙防火閥應安裝在緊靠墻或樓板的風管管段中，防火分區隔墻兩側的防火閥距墻表面不應大于200mm，防火閥兩側各2.0m范圍內的管道及其絕熱材料應采用不燃材料。

　　5, smoke fire pipe valve should be installed in the wall or floor close to the wind in the fire valve fire partition walls on both sides of the distance from the wall surface should be no more than 200mm, the pipeline fire valve on both sides of the range of 2.0m and the adiabatic material should use non combustible materials.
