有阀门的

Reducing gear drives cam rotate to top half-turn and link gear of upper gate move, top disc opens and discharges. Spring device makes disc close and replace with displacement of cam. When cam rotates to bottom half-turn link, gear of sub-layer gate moves, below disc opens and discharges. The disc closes little by little with the displacement of cam. These two actions maintain a closed state of either disc on the pipe. So it can discharges and lock air at the same time.?

减速装置带动凸轮旋转至上半圈时，上层阀门的连杆机构互动，阀板逐渐打开卸灰，随着凸轮的旋转，弹簧机构使阀板逐渐关闭复位；凸轮旋转至下半圈时，下层阀门的连杆机构互动，阀板逐渐打开卸灰，随着凸轮的旋转又使阀板逐渐关闭，这样两个动作使管道上阀板始终有一个是关闭状态，因而，可使卸灰与锁气同时达到目的。

If using digital locator precision by increasing the control valves to improve valve control performance, successful applications have if ND800 digital positioner for rotary control valves, we can make a variable range of process parameters increased by 50%, and then with the the characteristics of control valve valve positioner of the electronic properties of the match to further improve the control performance.

如采用数字定位器通过提高控制阀的精度来提高阀门的控制性能，成功的应用有如果将ND800数字定位器用于旋转控制阀，就能够使工艺参数的可变范围提高50％，再通过与控制阀的特性阀门定位器的电子特性的匹配来进一步提高控制的性能。

The valve has a threaded leak check port located on the side of the valve.

在阀门的侧面有一个车有螺纹的泄漏检查口。

Consideration of microstructure, the metal material has a face-centered cubic lattice of the austenitic steel, Reducing Valves copper and aluminum do not appear in the low temperature low temperature brittleness, but the hardness of aluminum and aluminum alloys is not high, the sealing surface of the wear-resistant aluminum , anti-scratch performance is poor, so the use of low-temperature valves have certain limitations, only used in low voltage and small-caliber valve.

从金相考虑，金属材料中具有面心立方晶格的奥氏体钢、铜和铝在低温状态下不会出现低温脆性，但因铝及铝合金的硬度不高，铝密封面的耐磨、耐擦伤性能差，所以在低温阀门中的使用有一定的限制，仅用于低压和小口径阀门中。
