Butterfly valve te pawh a awmindustrial pipeline-a valve chi khat tlanglawn tak an ni a, fluid control leh regulation-ah hmun pawimawh tak an chang a ni. An hnathawh dan pangngai leh himna tur atana routine maintenance kalpui mek zingah hian enfiahna hrang hrang neih a ngai a ni. He thuziakah hian, .TWSbutterfly valve-te endikna atana thil pawimawh tak takte leh a kaihhnawih standard-te a tarlang ang.
Butterfly valve hmel enfiahna atan chuan valve taksa, valve disc, valve stem, sealing surface, leh transmission device, etc. enfiah a huam ber a, valve body-ah hian a chunglam chhiatna, crack, holes, leh wear te enfiah tur a ni valve disc chu a deformation, crack, leh corrosion te, a thickness a remchan dan te enfiah tur a ni; valve stem chu a deformation, bending, leh corrosion a awm leh awm loh enfiah tur a ni; sealing surface chu a hrual em tih enfiah tur a ni a, scratch leh wear awm lo; transmission device chu a moving parts te connection a him em tih leh rotation a flexible em tih enfiah tur a ni.
A dimensional inspection chu abutterfly valve a nia ngaihtuah ber chu tehna pawimawh tak tak a ni a, chung zingah chuan valve body center-line leh connecting flange inkar perpendicularity, valve hawn degree, stem sei zawng, leh sealing surface thickness te pawh a tel. Heng dimension dik tak hi valve shut-off leh sealing performance atan a pawimawh hle a, international standard kaihhnawih angin finfiah a ngai a ni.
Butterfly valve sealing performance inspection hi test lian pahnih a awm a, chungte chu air tightness test leh leakage rate test te an ni. Air tightness test-ah hian hmanraw bik hmangin sealing surface-ah pressure hrang hrang dah a ni. Leakage rate test hian flow meter hmangin pressure hrang hrang hnuaia fluid leak zat a teh a, hei hian valve seal direct evaluation a pe a ni.
Butterfly valve atana pressure resistance test hian valve body chakna leh load hnuaia connection te a zirchiang thin. Tui emaw gas emaw chu medium atan hmangin valve chu pressure set hnuaiah test a ni a, deformation emaw cracking emaw a awm tih hriat theih a ni a, hei hian pressure a tuar thei tih a finfiah a ni.
Butterfly valve atana operating force test hian a hawn leh khar theihna tura force mamawh zat a teh thin. He force hian operational ease chu direct-in a nghawng a, compliance endik nan applicable standards nena teh leh tehkhin a ngai a ni.
Butterfly valve enfiahna hian thil pawimawh panga a huam a, chungte chu a lan dan, a zau zawng, sealing performance, pressure resistance, leh operating force te an ni. Area tin hi international emaw industry standard bik hmanga teh a ni. Heng standard zawm reng hi valve performance leh dam rei theihna tur a pawimawh hle a, chutih rualin accident venna atana pipeline system zawng zawng himna leh rintlakna tihchangtlun a pawimawh bawk.
I ngaihven avangin lawmthu kan sawi eTWS butterfly valve a ninihphung. Manufacturing leh inspection standard khauh tak kan zawm hi kan butterfly valve siamna bulpui ber a ni a, kan product range zawng zawngah, a huam tel bawkgate valve te a awm bawk, check valve te a awm bawk, lehboruak chhuahna valve te.
