Butterfly valve a nichu valve chi khat a ni a, disc hawn leh khar part hmangin 90° velin reciprocate a, medium flow rate hawn, khar emaw siamrem emaw a ni. Butterfly valve hian structure awlsam, a te, a rit lo, material consumption tlem, installation size te, driving torque te, simple leh fast operation a nei mai bakah flow regulation function tha tak leh closing sealing characteristic tha tak a nei bawk a, kum sawm kalta chhunga valve chi hrang hrang thang chak ber pawl a ni. Butterfly valve hi hman a ni nasa hle. A hmanna chi hrang hrang leh a tamna chu a zau zel a, temperature sang, pressure sang, diameter lian, tightness sang, dam rei, regulation characteristic tha tak, leh valve pakhat multi-function thlengin a thang chho zel bawk. A rintlakna leh performance indicator dangte pawh a sang hle.
Chemical resistant synthetic rubber hman a nih avanginbutterfly valve te pawh a awm, a performance a nibutterfly valve te pawh a awmtihchangtlun a ni tawh bawk. Synthetic rubber hian corrosion resistance, erosion resistance, dimensional stability, resilience tha, siam awlsam, man tlawm, etc. a neih avangin, synthetic rubber property hrang hrang nei chu hman dan hrang hrang a zirin a hnathawh dan tur a phuhruk theih nan thlan theih a nibutterfly valve te pawh a awm.
Polytetrafluoroethylene (PTFE) hian corrosion resistance chak tak, stable performance, kum upa awlsam lo, friction coefficient hniam, siam awlsam, dimensional stability, leh a comprehensive property tihchangtlun theih a nih avangin materials dik tak filling leh added hmangin, butterfly valve sealing material chak zawk leh friction coefficient hniam zawk nei chu hmuh theih a ni a, synthetic rubber-in a tihkhawtlai theihna chu a ni overcome, chuvangin PTFE-in a entîr polymer polymeric material leh a filling modified material chu butterfly valve-ah nasa takin hman a ni tawh a, chuvang chuan butterfly valve performance chu a ṭha chho lehzual a ni.Butterfly valve te pawh a awmtemperature leh pressure hrang hrang neiin, sealing performance rintlak leh service life rei zawk siam a ni tawh bawk.
Industrial application-a mamawh, temperature sang leh hniam, erosion chak tak, leh dam rei tak te phuhruk nan metal seal butterfly valve te nasa takin siam a ni. Butterfly valve-a temperature sang, temperature hniam, corrosion resistance chak, erosion resistance chak, leh alloy material chakna sang tak tak hman a nih avangin metal sealed butterfly valve hi industrial field-ah te hman a ni nasa hle a, chu chu temperature sang leh hniam, erosion chak, leh dam rei, leh butterfly valve diameter lian (9~750mm), pressure sang (42.0MPa) leh a zau te a ni temperature range (-196~606°C) a lo lang tawh a, chuvang chuan butterfly valve technology chuan level thar a thleng ta a ni.
Butterfly valve chu a inhawng kim chuan flow resistance tlem a nei a. Opening hi 15°~70° vel inkar a nih chuan sensitive flow control atan hman theih a ni a, chuvangin large-diameter adjustment field-ah butterfly valve hman hi a awm fo thin.
Butterfly valve butterfly plate wipeable motion avang hian butterfly valve tam zawk hi suspended solids nei media atan hman theih a ni. Seal chakna a zirin powder leh granular media atan pawh hman theih a ni.
Butterfly valve hi flow regulation atan a tha hle. Pipe chhunga butterfly valve pressure loss hi a lian tawk a, gate valve aiin a let thum velin a tam avangin butterfly valve thlan hunah pipeline system-a pressure loss-in nghawng a neih dan tur chu ngaihtuah kim vek tur a ni a, pipeline medium khar huna butterfly plate-in a pressure a tuar theihna tur chakna pawh ngaihtuah tur a ni. Chu bakah, elastomeric seat material chu temperature sang takah a awm theihna tur operating temperature-a tihkhawtlai te pawh ngaihtuah tel a ngai bawk.
Butterfly valve hian a siam sei zawng leh a san zawng zawng a tlem a, a hawn leh khar chakna a nei a, fluid control characteristic tha tak a nei bawk. Butterfly valve structural principle hi large-bore valve siam nan a tha ber a ni. Flow rate control nan butterfly valve hman a ngai a nih chuan butterfly valve lian leh chi dik tak thlan a pawimawh a, chutiang chuan a thawk tha thei ang.
A tlangpuiin throttling, regulation control leh mud medium-ah chuan structure sei zawng a tawi a, hawn leh khar speed a rang a, low pressure cut-off (pressure danglamna tlem) a ngai a, butterfly valve hman a tha. Butterfly valve hi two-position adjustment, diameter channel tihtlem, noise hniam, cavitation leh vaporization, boruak chhunga leakage tlemte, leh abrasive media te a awm chuan hman theih a ni. Hnathawh dan bik hnuaiah, throttling adjustment, emaw sealing khauh tak hnuaiah, a chhe nasa, temperature hniam (cryogenic) leh hnathawhna hmun dang.
