来源：http://www.cx-fire.com/ 日期：2022-08-05
消防阀门是专门设计应用于消防管道及消防气压供水设备和配套消防泵和气压罐及控制系统管路的专用阀门，消防专用信号阀门还可接受和处理各种消防信号以及发出各种运行工况信号。下面
川消小编为您讲讲吧。
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.
信号闸阀的启闭件是闸板，闸板的运动方向与流体方向相垂直，闸阀只能作全开和全关,不能作调节和节流。可用于控制空气、水、蒸汽、各种腐蚀性介质、泥浆、油品、液态金属和放射性介质等各种类型流体的流动。
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.
闸板有两个密封面,常用的模式闸板阀的两个密封面形成楔形、楔形角随阀门参数而异,通常为50,介质温度不高时为2°52'。楔式闸阀的闸板可以做成一个整体，叫做刚性闸板；也可以做成能产生微量变形的闸板,以改善其工艺性,弥补密封面角度在加工过程中产生的偏差,这种闸板叫做弹性闸板。信号闸阀一般是水平安装。
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.
弹性座封消防信号闸阀时常应用于自动喷水消防管路系统，来监控供水管路，可以远地指示阀门开度。弹性座封信号闸阀及附开度指示闸阀经常应用于消防给水系统，如果闸阀安装位置离地面较高时，一般选用升杆式闸阀，可以明显看见阀门开度指示，若安装位置较低。则需选用附开度指示闸阀。
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.
弹性座封消防信号闸阀的主要技术参数：公称压力：1.0Mpa、2.5Mpa；公称通径：50-400mm；试验标准：GB13927?AP1598；法兰标准：GB/T17241.6GB9113；工作温度：0-80℃；适用介质：水、油、气等。
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.
