應用范圍-
波紋管截止閥適用于水、油、氣體、易燃、易爆、劇毒、毒性流體、高溫導熱油、液氨、滲透性強、污染環(huán)境、帶放射性的流體介質等腐蝕性與非腐蝕性介質;
結構特點-
直通式•直角式•直流式•
閥桿升降位置指示，更直觀
閥桿調質及表面氮化處理，有良好的抗腐和抗摩擦性能;
雙重的密封設計,避免泄漏;
沒有流體損失，降低能源損失;
工作原理-
常閉狀態(tài)：閥瓣硬密封封在閥座凸上，形成一道硬質密封，*靜止密封；
先導狀態(tài)：開啟采用先導式即先打開，先導閉泄壓，使進口壓力降低，達到進出口壓力平衡，使閥門開啟，關閉時具有較小的力矩；
開啟狀態(tài)：雙閥瓣*開啟狀態(tài)，整體閥門處于全放空狀態(tài)，流體在閥門中的阻力較少，縮短了放空的時間，提高了閥門的放空效果。

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
