不锈钢阀门，其关键部件——金属波纹管，下端与阀杆组件采用自动滚焊焊接，上端与连接板自动滚焊焊接，在流体介质和大气之间形成一个金属屏障，确保阀杆零泄漏。阀瓣与阀体密封面经过精密研磨，组装完毕经过{bfb}试压，全部达到零泄漏。作为辅助密封，在波纹管上面依然保留了填料函，更增加了可靠性和安全性。高压阀门的金属波纹管均为多层结构，通过液压成形，可保证在{zd0}压力下10000次全行程开/关寿命。 不锈钢阀门使用优点： 1、双重的密封设计（波纹管+填料）若波纹管失效，阀杆填料也会避免泄漏，并符合国际密封标准。 2、安全环保，没有流体流失，降低能源损失，提高工厂设备安全。 3、使用寿命长，减少维修次数，降低经营成本。 4、坚固耐用的波纹管密封设计，保证阀杆的零泄漏，提供无需维护的条件。 不锈钢阀门使用范围： 适用于导热油、有毒、易燃、渗透性强、污染环境、带放射性的流体介质管路上作切断阀，也可用于调节，是创造无泄漏工厂的优质产品。

Stainless steel valves, its key components - metal bellows, bottom and stem components of automatic welding roll, roll the top and the interconnect automatic welding, in the fluid medium and form a metal barrier between the atmosphere, to ensure zero stem leakage. Valve flap and valve sealing surface after precision grinding, assembly, {bfb} after completion of pressure test, all to achieve zero leakage. As a secondary seal, the bellows are still retained the top stuffing, only increases the reliability and security. High-pressure valves are multi-layer structure of corrugated metal pipe through hydraulic forming, can guarantee the maximum pressure at 10,000 times the whole trip on / off life. Use the advantages of stainless steel valves: 1, double seal design (bellows + fill) if the bellows failure, valve stem packing will prevent leaks, and sealed in line with international standards. 2, safety and environmental protection, there is no fluid loss, reduce energy losses and improve plant safety equipment. 3, long life, reduced maintenance times, reducing operating costs. 4 rugged bellows seal design to ensure zero leakage of the valve stem to provide maintenance-conditions. Scope of use of stainless steel valves: Applied to heat-conducting oil, toxic, flammable, strong permeability, pollution of the environment with radioactive fluids to cut off pipeline valves can also be used to adjust the factory is to create quality products without leakage.
