进口低温闸阀认准德国洛克   

一、进口低温闸阀产品描述：

德国《LOCKE》洛克进口低温闸阀(Low temperature valve)采用深冷不锈钢为主体材料，完全避免使用过程中密封变形泄露，浸渍聚四氟乙烯的石棉为填料以柔性石墨为密封材料。这种材料对气体、液体均不渗透在厚度方向有10%-15 %的弹性较低的紧固压力就可达到密封,具有自润滑性用作，填料可以防止填料与阀杆的磨损。

The low temperature valve imported from Locke, Germany, uses cryogenic stainless steel as the main material to completely avoid seal deformation and leakage during use. The asbestos impregnated with polytetrafluoroethylene is used as the packing and the flexible graphite is used as the sealing material. This kind of material is impervious to gas and liquid. It can be sealed with a low elastic tightening pressure of 10% - 15% in the thickness direction. It has self-lubricating function. The packing can prevent the wear of the packing and the valve rod.

二、进口低温闸阀结构优点：

1、为防止中腔异常升压，在闸板的进口侧设置了泄压孔

2、根据阀门的工作温度确定阀盖的顶部长度，确保阀桿填料的可靠密封

3、根据工作温度合理选用填料，垫片等零件的材料

4、严格控制材料的化学成份及低温冲击韧性等力学性能指标

5、采用多种配管法兰标准及密封面型式，适用于各种工程需要

1. In order to prevent abnormal pressure rise in the middle chamber, a pressure relief hole is arranged at the inlet side of the ram

2. Determine the top length of the bonnet according to the operating temperature of the valve to ensure reliable sealing of the stem packing

3. Select the materials of packing, gasket and other parts reasonably according to the working temperature

4. Strictly control the chemical composition, low temperature impact toughness and other mechanical properties of materials

5. It adopts a variety of pipe flange standards and sealing face type, and is suitable for various engineering needs
