消防閥門是專門設計應用于消防管道及消防氣壓供水設備和配套消防泵和氣壓罐及控制系統管路的專用閥門，消防專用信號閥門還可接受和處理各種消防信號以及發出各種運行工況信號。下面
川消小編為您講講吧。
Fire valve is a special valve specially designed and applied to fire pipelines, fire pressure water supply equipment and supporting fire pumps, pressure tanks and control system pipelines. The special signal valve for fire control can also receive and process various fire signals and send signals under various operating conditions. Let's talk about it for you.
信號閘閥的啟閉件是閘板，閘板的運動方向與流體方向相垂直，閘閥只能作全開和全關,不能作調節和節流。可用于控制空氣、水、蒸汽、各種腐蝕性介質、泥漿、油品、液態金屬和放射性介質等各種類型流體的流動。
The opening and closing part of the signal gate valve is the ram, and the movement direction of the ram is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted and throttled. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.
閘板有兩個密封面,常用的模式閘板閥的兩個密封面形成楔形、楔形角隨閥門參數而異,通常為50,介質溫度不高時為2°52'。楔式閘閥的閘板可以做成一個整體，叫做剛性閘板；也可以做成能產生微量變形的閘板,以改善其工藝性,彌補密封面角度在加工過程中產生的偏差,這種閘板叫做彈性閘板。信號閘閥一般是水平安裝。
The ram has two sealing surfaces. In the common mode, the two sealing surfaces of the ram valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50. When the medium temperature is not high, it is 2 ° 52 '. The gate of wedge gate valve can be made into a whole, which is called rigid gate; It can also be made into a ram that can produce slight deformation to improve its processability and make up for the deviation of sealing surface angle during processing. This ram is called elastic ram. The signal gate valve is generally installed horizontally.
彈性座封消防信號閘閥時常應用于自動噴水消防管路系統，來監控供水管路，可以遠地指示閥門開度。彈性座封信號閘閥及附開度指示閘閥經常應用于消防給水系統，如果閘閥安裝位置離地面較高時，一般選用升桿式閘閥，可以明顯看見閥門開度指示，若安裝位置較低。則需選用附開度指示閘閥。
Elastic seat seal fire signal gate valve is often used in automatic sprinkler fire pipeline system to monitor the water supply pipeline and remotely indicate the valve opening. The resilient seated signal gate valve and the gate valve with opening indication are often used in the fire water supply system. If the installation position of the gate valve is higher than the ground, the rising stem gate valve is generally selected, and the opening indication of the valve can be clearly seen. If the installation position is lower. The gate valve with opening indication shall be selected.
彈性座封消防信號閘閥的主要技術參數：公稱壓力：1.0Mpa、2.5Mpa；公稱通徑：50-400mm；試驗標準：GB13927?AP1598；法蘭標準：GB/T17241.6GB9113；工作溫度：0-80℃；適用介質：水、油、氣等。
Main technical parameters of elastic seat seal fire signal gate valve: nominal pressure: 1.0MPa, 2.5MPa; Nominal diameter: 50-400mm; Test standard: gb13927? AP1598； Flange standard: gb/t17241.6gb9113; Working temperature: 0-80 ℃; Applicable media: water, oil, gas, etc.
