進(jìn)口低溫閘閥用心制造成就品質(zhì)德國(guó)洛克造

 一、進(jìn)口低溫閘閥產(chǎn)品描述：

德國(guó)《LOCKE》洛克進(jìn)口低溫閘閥(Low temperature valve)采用深冷不銹鋼為主體材料，完全避免使用過(guò)程中密封變形泄露，浸漬聚四氟乙烯的石棉為填料以柔性石墨為密封材料。這種材料對(duì)氣體、液體均不滲透在厚度方向有10%-15 %的彈性較低的緊固壓力就可達(dá)到密封,具有自潤(rùn)滑性用作，填料可以防止填料與閥桿的磨損。

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.

三、進(jìn)口低溫閘閥結(jié)構(gòu)優(yōu)點(diǎn)：

1、為防止中腔異常升壓，在閘板的進(jìn)口側(cè)設(shè)置了泄壓孔

2、根據(jù)閥門(mén)的工作溫度確定閥蓋的頂部長(zhǎng)度，確保閥桿填料的可靠密封

5、采用多種配管法蘭標(biāo)準(zhǔn)及密封面型式，適用于各種工程需要

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
