1. Leak awm chhan hriat chian
A hmasa berah chuan leak awm chhan dik taka hriat a ngai a ni. Leak hi thil chi hrang hrang avanga lo awm thei a ni a, chu chu sealing surface chhe, thil chhe, installation dik lo, operator tihsual, media corrosion te hi a ni. Leak lo chhuahna hmun hi enfiahna hmanrua leh hmanraw hmanga hriat theih a ni a, chu chu ultrasonic leak detector, mit hmuha enfiahna, leh pressure test te hmangin a hnu lama siamthatna tur lungphum nghet tak a ni.
Pahnihnaah chuan leakage part hrang hrang solution
1. Closing piece chu a tla thla a, leakage a siam thin
A chhan: Hnathawh \ha lo chuan closing parts te chu a tlakbuak emaw, upper dead center aia tam emaw a awm a, connection a chhe a, a chhe bawk a; Connector thlan chhuah material chu a dik lo a, medium-a corrosion leh machinery chhe lutuk chu a tuar thei lo.
Hrehawmna chinfel dan: Valve chu dik taka hmang la, chakna nasa lutuk avanga a kharna hmunte a tlakbuak emaw, a chhe emaw loh nan; Shut-off leh valve stem inzawmna chu a nghet em tih enfiah fo la, corrosion emaw wear emaw a awm chuan a hun takah connection chu thlak leh rawh Connector material chu corrosion resistance tha tak leh wear resistance tha tak nei thlang rawh.
2. Sealing ring inzawmna hmunah leakage a awm
A chhan: Sealing ring chu a roll nghet lo va; Sealing ring leh body inkara welding quality tha lo; Seal thread leh screw te chu a lo chhuak emaw, a chhe emaw a ni.
Solution: Sealing ring rolling place siam that nan adhesive hmang la; Welding chhiatna awmte siamthat leh weld leh; Thread leh screw chhe tawh emaw, chhe tawh emaw a hun taka thlak; Seal junction chu specification angin re-weld leh rawh.
3. Valve body leh bonnet atanga leak chhuak
A chhan: Thir casting-a casting quality a sang lo va, a chhiatna a awm a, chu chu sand hole, loose tissue, leh slag inclusions te hi a ni ni frozen cracked a ni a; Welding tha lo, slag inclusion, unwelding, stress crack, etc. ang chi chhiatna nei; Valve hi thil rit takin a rawn deng a, a chhiat phah a ni.
Solution: Casting quality tihchangtlun la, installation hmain strength test neih hmasak phawt ang che; Valve temperature hniam tak chu insulated emaw heat-mixed emaw a ni tur a ni a, valve hman tawh loh chu tui stagnant atanga paih chhuah tur a ni Weld hnathawh dan angin weld siam a, flaw detection leh strength test neih te; Valve-a thil rit tak takte nawr leh dah khap a ni a, cast iron leh non-metallic valve-te chu hand hammer hmanga vuak loh a ni bawk.
4. Sealing surface atanga leak awm
A chhan: sealing surface-a grinding inang lo; Stem leh shut-off inzawmna chu a dangling, a dik lo emaw, a chhe tawh emaw a ni; bent emaw misasembled stems emaw; Sealing surface material thlan dik loh.
Solution: Hnathawh dan azirin gasket material leh type thlan dik; Valve chu uluk takin siamrem la, a thawk tha thei ang; Bolt chu inang tlang leh symmetrically-in khauh takin khih la, torque wrench hmangin preload-in a mamawh a tlin theih nan; Static sealing surface-te chu a mamawh ang zela a tlin leh tlin loh enfiah nan siamthat, grinding leh coloring enfiahna; Gasket i dah dawnin tihfai hi ngaihven la, gasket chu leia a tlak loh nan.
5. Filler-ah leakage a awm
A chhan: filler thlan dik loh; Packing install dik lo; fillers te kum upa lam; A zung dikna a sang lo; Gland, bolt leh a dangte a chhe vek.
Solution: Hnathawh dan azirin packing material leh type dik tak thlang la; Specification angin packing dik taka dah; Filler upa tawh leh chhia te chu a hun takah thlak leh thin ang che; bent, worn stems tihdik, siamthat emaw thlak danglam; Gland, bolt leh thil dang chhia te chu a hun takah siamthat emaw thlak emaw tur a ni a; Operating procedure zawm la, valve chu constant speed leh normal force-in operate rawh.
3. Invenna kawng hrang hrang
1. Inspection leh maintenance neih fo: Valve hman tam dan leh hnathawhna hmun azirin maintenance plan mumal tak siam rawh. Valve chhung leh pawn lam tihfai te, fastener te a lo hrual leh hrual loh enfiah te, transmission parts te lubricate te, etc. Scientific maintenance hmang hian harsatna awm thei te chu a hun takah hmuhchhuah theih a ni a, valve service life rei zawk nan a chinfel theih bawk.
2. Valve quality tha thlang rawh: Valve leakage hlauhawmna chu a bulpui berah tihtlem nan valve product tha tak tak thlan a ngai a ni. Material thlan atanga structural design atanga production process thlengin valve products te hi a tha ber tur a nih theih nan khauh taka control a ni. Hman dan dik leh dah dan: Hman dan tur zawm la, valve dik taka hman tur. Installation kalpui chhung hian valve chu a pangngai anga hawn leh khar theih a nih theih nan installation awmna leh a kalna tur ngaihtuah tur a ni. Chutih rual chuan valve-ah chakna nasa lutuk emaw, valve-a vuak emaw pawh pumpelh tur a ni.
A awm a nih chuana rilru a buai em em a, a rilru a hah em em bawk a, .gate valve a ni, check valve, Y-strainer, i biak theih bawkTWS VALVE a ni.
