Siam chhuah a nivalve a nis te hian performance test hrang hrang an paltlang a ngai a, chung zinga pawimawh ber chu pressure testing a ni. Pressure test hi valve-in a tuar theih pressure value hian production regulation-a thil phut a tlin leh tlin loh enfiahna a ni.TWS-ah chuan...butterfly valve thut nêm tak a ni, chu chu high pressure seat tightness test neih a ngai a ni. PN vawi 1.5-a pressure tarlan chu test tuiah hman tur a ni.
Thu pawimawh tak tak:Pressure Testing neih a ni;Butterfly Valve ṭhutna nem tak a ni; Pressure Seat Tightness Test a ni
A tlangpuiin, pressure test ofvalve te a awma hnuaia thu bul leh fimkhur turte hi a zawm tur a ni:
(1) A tlangpuiin, avalve a nichakna test hnuaiah a awm lo a, mahse avalve a nitaksa leh bonnet siamthat hnuah emaw avalve a nibody leh bonnet corrosion damage nei te chu a chakna enfiah tur a ni. Safety valve atan chuan a pressure awm reng, reseating pressure leh test dangte chu a thupek leh a kaihhnawih dan tarlan angin a zawm tur a ni.
(2) A chakna leh tightness test hi a hmain tih tur a nivalve a nia install tawh a ni. Low-pressure valve 20% chu spot-check a ni a, 100% chu a tling lo a nih chuan enfiah tur a ni; Medium leh high-pressure valve 100% vel enfiah tur a ni.
(3) Test neih chhung hian installation position avalve a nienfiah awlsamna lam hawi tur a ni.
(4) A chhan chuvalve te a awmwelded connection angin blind plate pressure test hman theih loh chuan conical seal emaw O-ring seal emaw hmangin pressure test theih a ni. (5) Hydraulic test neih chhung hian a theih ang anga valve air chu paih chhuah tur a ni.
(6) Test neih chhung hian pressure chu zawi zawiin tihsan tur a ni a, sharp leh sudden pressure siam phal a ni lo.
(7) Strength test leh sealing type test hun chhung hi a tlangpuiin minute 2-3 vel a ni a, valve pawimawh leh special te chu minute 5 chhung a daih tur a ni. Diameter tenau valve te test hun chu a inmil tawkin a tawi thei a, diameter lian valve te test hun pawh a rei thei bawk. Test chhung hian rinhlelhna a awm chuan test hun pawhsei theih a ni. Strength test neih chhung hian thawmhnaw emaw leakage emaw a awm avalve a nibody leh bonnet hman phal a ni lo. Sealing test hi general atan vawi khat chauh tih a nivalve te a awm, leh safety valve atan vawi hnih, high-pressurevalve te a awmleh thil pawimawh dangte pawh a nivalve te a awm. Test neih chhung hian pressure hniam leh diameter lian tak nei valve pawimawh lo leh leakage awm theihna tur regulation nei valve te tan leakage tlemte phalsak a ni a general valve, power station valve, marine valve leh valve dangte mamawh hrang hrang avang hian leakage mamawh chu hetiang hi a ni tur a ni: Dan kaihhnawih angin tihhlawhtlin.
(8) Throttle valve hi closing part-a tightness test neih loh tur a ni a, mahse packing leh gasket-a strength test leh tightness test tih tur a ni. (9) Pressure test lai hian valve khar theihna chakna chu mi pakhat taksa chakna pangngaiin chauh khar phal a ni a; lever ang chi hmanrua hmanga chakna hman phal a ni lo (torque wrench tih loh chu). Handwheel diameter chu 320mm aia tam emaw, a tlukpui emaw a nih chuan mi pahnih hna thawh dun phalsak an ni. khar a ni.
(10) Valve chunglam seal nei tan chuan packing chu tightness test atan lakchhuah tur a ni. Upper seal a khar hnuah leakage a awm leh awm loh enfiah thin ang che. Gas test atan i hman dawnin stuffing box-a tui awm chu enfiah thin ang che. Packing tightness test kan tih hian upper seal chu tight position-ah dah phal a ni lo.
(11) Driving device nei valve eng pawh tan chuan a tightness test hunah driving device hmangin valve khar tur a ni a, tightness test neih tur a ni. Kut hmanga khalh device tan chuan kut hmanga khar valve sealing test pawh tih tur a ni.
(12) Strength test leh tightness test zawhah main valve-a bypass valve dah chu main valve-ah a chakna leh tightness test tur a ni a; main valve kharna hmun hawn a nih chuan chutiang chuan hawn tur a ni bawk.
(13) Cast iron valve chakna test lai hian valve body leh valve cover chu copper bell hmangin tap la, leakage a awm leh awm loh enfiah rawh.
(14) Valve test a nih hian, sealing surface-a oil dah theihna plug valve tih loh chu, valve dangte chuan sealing surface chu oil hmanga test phal a ni lo.
(15) Valve pressure test lai hian valve chunga blind plate pressing force chu a lian lutuk tur a ni lo, chutiang chuan valve deformation a awm loh nan leh test effect a nghawng thei ang (cast iron valve chu press khauh lutuk a nih chuan a chhe vek ang).
(16) Valve-a pressure test zawh hnuah valve chhunga tui awmkhawm chu a hun takah paih chhuakin phihfai fai tur a ni a, test record pawh siam tur a ni.
In TWS Valve a ni, kan thil siam ber, soft seated butterfly valve chungchangah chuan, high pressure seat tightness test a phur tur a ni. Tin, test medium chu tui emaw gas emaw a ni a, test medium temperature chu 5 inkar a ni°C a ni~40 a ni°C a ni.
Tin, a hnuaia testing hi shell leh valve performance tightness a ni.
A tum ber chu test hian a chhunga pressure laka operating mechanism sealing telin shell leak tightness a nemnghet tur a ni.
Test kalpui chhung hian test fluid chu tui a ni tur a ni tih kan hriat a ngai a ni.
Tin, valve disc chu a then inhawng position-ah a awm tur a ni.Valve tawp connection te chu blank off tur a ni a, cavities zawng zawng chu test tuiin a khat tur a ni. PN vawi 1.5-a pressure tarlan chu test tuiah hman tur a ni.
