二、进口气动薄膜调节阀主要特点：

1.顶底、层双导向双座调节阀，工作时稳定性好。

2.有两个阀芯和阀座，采用“四通”阀体，可以方便地由正装改装成反装，气关阀变气开阀。

3.阀体按流体动力学原理设计的等截面低流阻流道，额定流量系数大。

4.不平衡力小，允许使用压差较大。

5.执行机构采用多弹簧结构，高度减小30%。重量减轻30%。

6.可调范围大，固有可调比为50%。

7.LXNV型波纹管密封型调节阀对移动的阀杆形成了完全密封，堵绝流体外漏。

8.LXNJ型调节阀带有保温夹套，用于流体冷却后易结晶、凝固造成堵塞的场合。

2、 Main features of imported pneumatic diaphragm control valve:

1. Double guide and double seat control valve at the top and bottom, with good stability.

2. There are two valve cores and valve seats, and the "four-way" valve body is adopted, which can be easily refitted from normal installation to reverse installation, and the gas closing valve can be changed into gas opening valve.

3. The valve body is designed according to the principle of fluid dynamics, with low flow resistance and constant cross-section, and large rated flow coefficient.

4. The unbalanced force is small and the allowable pressure difference is large.

5. The actuator adopts multi spring structure, which reduces the height by 30%. 30% weight reduction.

6. Wide adjustable range, inherent adjustable ratio is 50%.

7. Lxnv bellows seal type control valve forms a complete seal to the moving valve stem to block fluid leakage.

8. Lxnj type control valve is equipped with heat preservation jacket, which is used in the occasions where the fluid is easy to crystallize and solidify after cooling.

三、进口气动薄膜调节阀描述：

德国DE LOCKE洛克进口气动薄膜调节阀由气动薄膜执行机构和调节阀两大部分组成，它与气动调节器，减压阀、定位器或其他仪表配合使用，达到控制管道内的温度、压力、液位、流量等工艺参数。单座调节阀具有易密封，泄漏量小的优点，但平衡力较大，故工作压差不宜过高。双座调节阀具有流量系数大，不平衡力较小的特点，因而使用广泛。主要用于调节气体、液体、蒸汽等介质，用在电厂，钢铁厂，制糖，洗煤选矿等化工领域。

3、 Description of inlet pneumatic diaphragm control valve:

The pneumatic diaphragm control valve imported from Germany de lock is composed of pneumatic diaphragm actuator and control valve. It is used together with pneumatic regulator, pressure reducing valve, positioner or other instruments to control the temperature, pressure, liquid level, flow and other process parameters in the pipeline. Single seat control valve has the advantages of easy sealing and small leakage, but the balance force is large, so the working pressure difference should not be too high. Double seat control valve has the characteristics of large flow coefficient and small unbalanced force, so it is widely used. It is mainly used to regulate gas, liquid, steam and other media. It is used in power plant, iron and steel plant, sugar making, coal washing, mineral processing and other chemical fields.
