I. Hrilhfiahna atana thu bulteButterfly Valve te pawh a awm
1. Structure chi hrang hrang thlan dan
Center butterfly valve (center line chi hrang hrang) a awm a.:Valve stem leh butterfly disc te hi centrally symmetrical a ni a, structure awlsam tak leh man tlawm tak a ni. Sealing hi rubber soft seal ah a innghat a ni. Temperature leh pressure pangngai leh thil tih tur khauh tak nei lo hun atan a tha hle.
A rilru a buai em em a, a rilru a hah em em bawk a.Valve stem hi butterfly disc lairil atanga offset a ni a, hei hian a hnathawh laiin sealing surface inkara friction a ti tlem a, service life a ti rei bawk. Medium leh low-pressure application, hawn leh khar fo ngai tan a tha hle.
Double eccentric butterfly valve (butterfly valve hnathawhna sang tak nei):Valve stem hi butterfly disc leh sealing surface center pahnih atanga offset a nih avangin frictionless operation a awm thei a ni. A tlangpuiin metal emaw composite sealing emaw a hmang thin. Temperature sang, pressure sang, corrosive, emaw particulate media atan a tha hle.
Three-eccentric butterfly valve chu a awm a:Dual eccentricity leh beveled conical sealing pair te inzawmkhawm chuan zero friction leh zero leakage a nei thei a, high-temperature leh high-pressure resistance a nei bawk. Hnathawh harsa tak (eg, steam, oil/gas, high-temperature media) atan a tha hle.
2. Drive mode thlan dan tur
Kuta thawh:diameter te tak te (DN≤200), low-pressure, emaw, hnathawh tam lohna hmunah te tan.
Worm gear khalh chhuahna: 1.1.Medium to large diameter application atana tha, thawhrimna tel lova hnathawh emaw flow regulation emaw mamawhna atan a tha.
Pneumatic/Electric hmanga siam a ni:Remote control, automation system, emaw, rang taka khar ngai (eg, kangmei alarm system, emergency shutdown).
3. Sealing bungrua leh bungrua
Soft seal (rubber, PTFE, etc.): sealing tha tak, mahse temperature leh pressure resistance tlem (a tlangpuiin ≤120°C, PN≤1.6MPa). Tui, boruak leh corrosion media chak lo tan a tha.
Metal seal (stainless steel, cemented carbide): Temperature sang (600°C thleng), pressure sang, leh wear leh corrosion do theihna, mahse sealing performance erawh soft seal aiin a hniam deuh thung. Metallurgy, power plant, leh petrochemicals-a high-temperature media atan a tha.
Taksa thil: Cast iron, carbon steel, stainless steel, alloy steel, emaw plastic/rubber lining emaw chu medium a chhe thei dan azirin a ni.
4. Pressure leh temperature inkar: 1.1.
PN10~PN16 atan hian soft-sealed butterfly valve hman a ni tlangpui a, a temperature chu ≤120°C a ni. Three-eccentric metal-sealed butterfly valve hian PN100 aia sang a thleng thei a, a temperature chu ≥600°C a ni.
5. Traffic ziarang
Flow regulation a ngai hunah chuan butterfly valve linear emaw percentage inang emaw flow characteristic nei (eg, V-shaped disc) thlang rawh.
6. Installation space leh flow direction: 1.1.Butterfly valve hian a structure compact tak a nei a, hei vang hian pipeline hmun tlemte nei tan pawh a tha hle. A tlangpuiin flow direction khapna a awm lo va, mahse three-eccentric butterfly valve tan chuan flow direction chu tarlan a ngai a ni.
II. Hun hman dan tur
1. Tui humhalh leh Tui Supply & Drainage System: Khawpui tui supply, kangmei laka invenna piping, leh bawlhhlawh sawngbawlna: soft-sealed centerline butterfly valve hman tlangpui a, a man tlawm a, sealing rintlak tak a nei bawk. Pump outlet leh flow regulation atan: worm gear emaw electric control butterfly valve emaw thlang rawh.
2. Petrochemical leh natural gas pipeline: High-pressure resistance leh leak venna atan eccentric metal-sealed butterfly valve pathum thlan chhuah a ni. Corrosive media (eg, acids/alkalis): Fluorine-lined butterfly valve emaw, corrosion-resistant alloy valve emaw hman a ni.
3. Power industry, tui circulating system, leh flue gas desulfurization atan: medium emaw double eccentric rubber-lined butterfly valve te. Steam pipeline (eg, power plant-a auxiliary equipment system) tan: eccentric metal-sealed butterfly valve pathum.
4. HVAC (Heating, Ventilation, and Air Conditioning) tui lum leh lum circulation system: flow control emaw cutoff emaw atan soft-sealed butterfly valve.
5. Marine engineering leh tuifinriat tui pipeline atan: corrosion-resistant duplex stainless steel butterfly valve emaw rubber-lined butterfly valve emaw.
6. Chaw leh medical-grade butterfly valve (polished stainless steel, quick-connect fittings) te hian sterile mamawh a tlin.
7. Hnathawh tur bik hmuna dust leh particulate media: Wear-resistant hard-sealed butterfly valve hman a tha (eg, mine powder conveying atan).
Vacuum system: Vacuum bik a awmbutterfly valve a nisealing performance a tichiang.
III. Tawpna
TWSquality sang tak nei tura thawhpui rintlak mai a ni lobutterfly valve te pawh a awmmahse technical expertise zau tak leh proven solutions ingate valve te a awm bawk, check valve te a awm bawk, lehboruak chhuahna valve te. I fluid control mamawh chu eng pawh ni se, professional, one-stop valve support kan pe a ni. Collaboration awm thei emaw technical inquiry nei duh tan engtik lai pawhin min rawn biak theih reng e.
