气动阀门的工作原理是什么?

阀门的功能是拦截液体或气体,使其不能自由通过。不同类型的阀门有不同的用途。气动球阀是一种广泛应用于航空煤油、天然气、液化气、输气管道等管道的阀门。下面我们上海阀门厂家就气动球阀的工作原理组成部分进行分享和解读!
The function of the valve is to intercept liquid or gas so that it cannot pass freely. Different types of valves have different purposes. Pneumatic ball valve is a valve widely used in aviation kerosene, natural gas, liquefied gas, gas transmission pipeline and other pipelines. Now we Shanghai valve manufacturers share and interpret the working principle and components of pneumatic ball valve!
气动球阀的工作原理可以详细分为以下几个部分:
The working principle of pneumatic ball valve can be divided into the following parts in detail:
阀门关闭:
Valve closed:
当阀门关闭时,转动手轮,使水龙头和密封滑块旋转90度,然后向下移动水龙头。随着扳手的移动,密封阀芯被推入阀门内腔盖,直到弹性密封圈均匀拧紧,使阀孔的上下端形成密封。
When the valve is closed, first turn the hand wheel to rotate the faucet and sealing slider 90 degrees, and then move the faucet downward. With the movement of the wrench, the sealing valve core is pushed into the inner cavity cover of the valve until the elastic sealing ring is tightened evenly, so that the upper and lower ends of the valve hole form a seal.
阀门开度:
Valve opening:
当阀门打开时,转动手轮,抬起扳手并将密封滑块从阀体两侧的密封面上拉回。当滑板完全缩回并离开阀体密封面时,继续旋转手轮,使水龙头和密封滑板旋转90,阀门处于开启位置。
When the valve is opened, first turn the hand wheel, lift the wrench and pull the sealing slider back from the sealing surfaces on both sides of the valve body. When the sliding plate fully retracts and leaves the sealing surface of the valve body, continue to rotate the hand wheel to rotate the faucet and sealing sliding plate by 90, and the valve is in the open position.
关于密封:
About sealing:
弹性密封圈形成在滑板的凹槽中。随着密封滑板进入阀门的入口和出口,密封圈逐渐压入凹槽中。加工后的滑板表面与阀门内腔形成两部分金金属密封,防止弹性密封圈持续受压,具有阻燃功能。
The elastic sealing ring is formed in the groove of the sliding plate. As the sealing sliding plate enters the inlet and outlet of the valve, the sealing ring is gradually pressed into the groove. The processed sliding plate surface forms two parts of gold metal seal with the inner cavity of the valve to prevent the continuous compression of the elastic seal ring, which has the function of flame retardant.
双重通风:
Dual ventilation:
这是一种通过两个截止阀和一个中间阀完全隔离两端管道的方法。球阀关闭两个主阀并打开阀,以提高系统性。如果阀门开始泄漏,过滤介质可能从打开的阀流出。
This is a method to completely isolate the pipes at both ends through two stop valves and an intermediate safety valve. The ball valve closes the two main valves and opens the safety valve to improve the safety of the system. If the valve begins to leak, the filter medium may flow out of the open safety valve.
双重密封模式:
Double seal mode:
两个独立的密封滑块牢固地压入阀孔的上下端(双重密封)。当阀门关闭时,溢流阀打开,以检查密封效果(排放)。
Two independent sealing sliders are firmly pressed into the upper and lower ends of the valve hole (double sealing). When the valve is closed, the overflow valve opens to check the sealing effect (discharge).
