阀门

As the valve is a wide range of uses, it is the role of a great one.

由于阀门的用途是广泛的，因此它起的作用也是很大的。

To actuate all valves it is necessary to provide certain data to assure proper sizing and prevent damage to the system.

为了驱动所需的阀门，有必要提供某些参数，以保证能够恰当选择所需的执行机构，防止损坏系统。

Corrosion products formed by these reactions can prevent normal valve operation and can become embedded in the elastomeric stem tip, preventing the valve from making a complete seal.

这些反应产生的腐蚀产物会阻止正常的阀门运转，深入到人造橡胶阀杆顶端，造成阀门不能完全密封。
