空调系统阀门一般可以分为三类:密闭阀、调节阀和放火阀。
Air conditioning system valves can generally be divided into three categories: closed valve, regulating valve and fire release valve.
密闭阀:起开关作用,要求全开时阻力小,全闭时密闭性能好。如:新风密闭阀和排风密闭阀。
Closed valve: it plays the role of opening and closing. It is required that the resistance is small when it is fully opened and the sealing performance is good when it is fully closed. Such as: fresh air sealing valve and exhaust air sealing valve.
调节阀:在系统中主要起运行调节作用,常常安装在系统的送回风管路上。按照执行特点,又可以分为经常调节阀和一次性调节阀两种。经常调节阀常见的有对开多叶阀和平行多叶阀等;一次性调节阀主要为系统及各个分支各管段达到设计风量进行调节使用的,此种阀门主要起增加阻力作用,并且调节前后阀门的位置一般比变动。
Regulating valve: it mainly plays the role of operation regulation in the system and is often installed on the supply and return air pipeline of the system. According to the implementation characteristics, it can be divided into two types: regular control valve and one-time control valve. The common regulating valves are split multi leaf valve and parallel multi leaf valve; The one-time regulating valve is mainly used for regulating the system and each branch and pipe section to reach the design air volume. This valve is mainly used to increase the resistance, and the position of the valve before and after the regulation is generally changed.
常用的一次性调节阀门主要有:蝶阀——安装在较小风管的送回风支管上;三通调节阀——主要用于调节两个支管的风量比例,常安装在回风管路和排风管路上面;多叶阀(平行型和对开型);插板阀等
The commonly used one-time regulating valves mainly include: butterfly valve - installed on the supply and return air branch pipe of the smaller air pipe; Three way regulating valve - mainly used to regulate the air volume ratio of the two branch pipes, often installed on the return air pipeline and exhaust air pipeline; Multi leaf valve (parallel type and split type); Insert plate valve, etc
防火阀:在发生火灾时自动关闭,以切断风管通路。原理是利用阀板本身的重量进行关闭的,阀板一般成偏心,重的一端用钢丝拉起,钢丝上安装易熔合金片,保持阀门的开启,当风管气流温度超过设定温度时,合金片熔断,阀门自动关闭。同时,放火阀可连接信号报警装置,及时进行报警。
Fire damper: automatically close in case of fire to cut off the air duct passage. The principle is to use the weight of the valve plate itself to close. The valve plate is generally eccentric. The heavy end is pulled up with steel wire, and the fusible alloy sheet is installed on the steel wire to keep the valve open. When the air flow temperature of the air duct exceeds the set temperature, the alloy sheet will fuse and the valve will close automatically. At the same time, the fire valve can be connected with the signal alarm device to give an alarm in time.
除此之外,空调系统阀门按用途和作用还可以分为截断阀类和调节阀类。
In addition, air conditioning system valves can be divided into block valves and regulating valves according to their uses and functions.
截断阀类:主要用于截断或接通介质流.包括闸阀、截止阀、隔膜阀、球阀、旋塞阀、碟阀、柱塞阀、球塞阀、仪表针形阀等。
Block valves: mainly used to block or connect the medium flow Including gate valve, globe valve, diaphragm valve, ball valve, plug valve, butterfly valve, plunger valve, ball plug valve, instrument needle valve, etc.
调节阀类:主要用于调节介质的流量、压力等.包括调节阀、节流阀、减压阀等。
Regulating valves: mainly used to regulate the flow and pressure of medium, including regulating valves, throttle valves, pressure reducing valves, etc.
止回阀类:用于阻止介质倒流.包括各种结构的止回阀。
Check valves: used to prevent the backflow of medium, including check valves of various structures.
分流阀类:用于分离、分配或混合介质.包括各种结构的分配阀和疏水阀等。
Diverter valves: used for separating, distributing or mixing media, including distribution valves and drain valves of various structures.
安全阀类:用于介质超压时的安全保护.包括各种类型的安全阀。
Safety valves: used for safety protection in case of medium overpressure, including various types of safety valves.
