美国泰乐TYLER进口波纹管截止阀
产品描述-
美国泰乐TYLER进口波纹管截止阀是管道流体控制通用设备,采用填料辅助双层波纹管密封,双重坚固耐用的波纹管密封设计保证阀杆的零泄漏,没有流体损失，提高工厂设备安全。
应用范围-
波纹管截止阀适用于水、油、气体、易燃、易爆、剧毒、毒性流体、高温导热油、液氨、渗透性强、污染环境、带放射性的流体介质等腐蚀性与非腐蚀性介质;
结构特点-
直通式•直角式•直流式•
阀杆升降位置指示，更直观
阀杆调质及表面氮化处理，有良好的抗腐和抗摩擦性能;
双重的密封设计,避免泄漏;
没有流体损失，降低能源损失;
工作原理-
常闭状态：阀瓣硬密封封在阀座凸上，形成一道硬质密封，*静止密封；
先导状态：开启采用先导式即先打开，先导闭泄压，使进口压力降低，达到进出口压力平衡，使阀门开启，关闭时具有较小的力矩；
开启状态：双阀瓣*开启状态，整体阀门处于全放空状态，流体在阀门中的阻力较少，缩短了放空的时间，提高了阀门的放空效果。
技术参数-
连接方式:法兰、焊接、内螺纹;
传动方式:手动[DN15-DN300];
工作压力:PN1.6-PN16Mpa;
介质温度:－40℃-420℃;

American TYLER TYLER inlet bellows globe valve
Product description -
The Thai music TYLER imported corrugated pipe cut-off valve is general pipeline fluid control equipment, adopting auxiliary double bellows seal packing, double durable bellows seal design ensures zero leakage of the stem, no fluid loss, improve the plant equipment safety.
Application scope -
Bellows globe valve is suitable for water, oil, gas, inflammable, explosive, toxic, toxic fluid permeability, high temperature heat conduction oil, liquid ammonia, strong, environmental pollution, with radioactive fluid medium such as corrosion resistance with the corrosive medium;
Structural features -
Direct and rectangular • straight flow
Stem elevation position indicator, more intuitive
The stem and surface nitride treatment have good anti-corrosion and anti-friction properties.
Double seal design to avoid leakage;
No fluid loss, reduce energy loss;
Working principle -
Normally closed: the disc is hard sealed and sealed to the seat, forming a hard seal, compley static seal;
Lead mode: open first, first open, lead closed release pressure, reduce the inlet pressure, reach the inlet and outlet pressure balance, make the valve open, and have a smaller torque when closing;
Open state: the double disc is fully open, the whole valve is in full release state, the fluid in the valve has less resistance, shortening the time of release, and improving the air discharge effect of the valve.
Technical parameters -
Connection: flange, welding, internal thread;
Transmission mode: manual [dn15-dn300];
Work pressure: pn1.6-pn16mpa;
Medium temperature: - 40 ℃ - 420 ℃;
Body material: carbon steel, stainless steel;
Sealing material: stainless steel disc, stainless steel bellows, double seal;
Filling: flexible graphite;
Stem material: stainless steel 304, stainless steel 316, stainless steel 2cr13;
Body surface: cast steel: subpurple orchid, stainless steel: color
