通风管道是建筑工程中必不可少的通风设备，它为建筑提供了方便有效的通风，使建筑内的空气能够保持循环。然而，通风管道有时会出现问题，如调节阀。通风管道制造企业介绍了调节阀存在的两个常见问题及解决方案。
Ventilation pipeline is an indispensable ventilation equipment in building engineering. It provides convenient and effective ventilation for buildings, so that the air in buildings can maintain circulation. However, ventilation pipes sometimes have problems, such as control valves. Ventilation pipe manufacturer introduced two common problems and solutions of control valve.
一个是交通拥堵。不锈钢调节阀具有较高的调节精度，一般为直线调节阀，阀体结构多为倒S型，存在循环死角，容易产生堵塞现象。特别是在新安装的管道或大修运行的初期，由于此时管道内有大量的焊渣、铁锈等杂物，很容易造成节流孔及导向位置介质堵塞。
One is traffic jam. Stainless steel control valves have high regulation accuracy, generally linear control valves, valve body structure is mostly inverted S-shaped, there is a cycle dead angle, prone to blockage. Especially in the initial stage of newly installed pipeline or overhaul operation, because there are a large number of welding slag, rust and other impurities in the pipeline at this time, it is easy to cause throttle hole and guide position medium blockage.
解决方案:可快速打开、关闭二次管路或不锈钢调节阀，通过介质压力将杂物。或用管夹夹住阀杆，除信号压力外，正、负旋转阀杆阀芯闪过阀卡。也可增加气源压力反复上下移动，以达到松卡的地方。
Solution: It can quickly open and close secondary pipeline or stainless steel regulating valve, and remove debris through medium pressure. Or clamp the stem with a pipe. In addition to signal pressure, the positive and negative rotating stem spool flashes over the valve card. It can also increase the pressure of the air source to move up and down repeatedly to reach the place where the card is loose.
另一个是泄漏。一般不锈钢阀门由于结构设计等因素，允许有一定的泄漏量。但当不锈钢控制阀关闭状态,渗漏严重,通常由于阀杆的长度不合适的原因:不锈钢控制阀打开,当阀杆太长,上下运动距离不够,造成阀芯和阀的差距,不能正常关闭。解决办法是调整不锈钢调节阀阀杆，阀杆长度合适，可以正常关闭。
The other is leakage. Generally, stainless steel valves allow certain leakage due to structural design and other factors. But when the stainless steel control valve is closed, the leakage is serious. Usually due to the length of the stem is not appropriate: the stainless steel control valve opens, when the stem is too long, the upper and lower motion distance is not enough, resulting in the gap between the spool and the valve, can not normally close. The solution is to adjust the valve stem of stainless steel regulating valve. The stem length is suitable and can be closed normally.
以上就是介绍控制阀容易出现的两个问题，一般来说，根据以上的解决方案都是很好的解决问题的，希望对您有所帮助。
The above is to introduce the control valve easy to appear two problems, generally speaking, according to the above solutions are very good to solve the problem, I hope to help you.
