1. Valvensinya wa nawu wa ku hlawula:
Valve leyi hlawuriweke yifanele ku fikelela milawu ya xisekelo leyi landzelaka.
(1) Vuhlayiseki na ku tshembheka ka tikhemikhali ta petroliyamu, xitichi xa gezi, vumaki bya nsimbi na tiindasitiri tin’wana swi lava ntirho lowu yaka emahlweni, lowu tiyeke, wa xirhendzevutani xo leha. Hikwalaho, valve yi fanele ku va na ku tshembheka ka le henhla, xivangelo xa vuhlayiseki, hayi hikwalaho ka ku tsandzeka ka valve ku vange vuhlayiseki lebyikulu bya vuhumelerisi na mhangu ya ku vaviseka ka munhu hi xiyexe, ku fikelela xilaveko xa ntirho wa xirhendzevutani xo leha, vuhumelerisi byo leha bya xirhendzevutani lebyi yaka emahlweni i vuyelo, ku engetela, ku hunguta kumbe ku papalata ku vupfa loku vangiwaka hi valve, ku tumbuluxa fektri leyi tengeke, leyi hluvukeke, HsE (i.e., rihanyo, vuhlayiseki, mbango) vulawuri.
(2) Ku fikelela swilaveko swa vuhumelerisi bya phurosese valve yi fanele ku fikelela ku tirhisiwa ka ntshikelelo wa le xikarhi, wa ntirho, mahiselo yo tirha na swilaveko swa matirhiselo, leswi nakambe swi nga swilaveko swa xisekelo swa ku hlawuriwa ka valve. Loko swilava valve overpressure protection role, discharge excess medium, yifanele ku hlawula safety valve, overflow valve, yifanele ku sivela operation process ya medium backflow, yifanele kutirhisa check valve, yifanele ku herisa hiku tisungulela steam pipe na switirhisiwa swa condensate, moya na swin’wana swinga koti ku condensing gasi, naswona ku sivela steam escape, yifanele ku hlawula drain valve. Ku engetela kwalano, loko medium yiri na corrosive, switirhisiwa swa kahle swo lwisana na corrosion swifanele ku hlawuriwa.
(3) Endzhaku ka ntirho, ku vekiwa, ku kambela (ku hlayisa) ku lunghisa ka valve, mutirhisi u fanele ku kota ku vona kahle tlhelo ra valve, swikombiso swo pfula, swikombiso swa swikombiso, ku olova ku hi nkarhi na ku tirhana hi xiboho na swihoxo swo hambana swa xihatla. Hi nkarhi walowo, xivumbeko xa muxaka wa valve lexi hlawuriweke xifanele kuva kuya fika laha swinga kotekaka cylinder sheet, ku vekiwa, ku kambela (ku hlayisa) ku lunghisa swi olova.
(4) Ikhonomi Hi ku ya hi ku fikelela matirhiselo ya ntolovelo ya tiphayiphi ta phurosese, tivalvu leti nga na ntsengo wa le hansi wa vumaki na xivumbeko xo olova ti fanele ku hlawuriwa hilaha swi kotekaka hakona ku hunguta ntsengo wa xitirhisiwa, ku papalata ku tlangisiwa ka switirhisiwa swo ka swi nga tirhisiwanga swa tivalvu na ku hunguta ntsengo wa ku vekiwa ka tivalvu na ku hlayisa eka xiteji xa le ndzhaku.
2. Magoza yo hlawula valve: .
Ti valve to hlawula hi ntolovelo ti landzelela magoza lawa ya landzelaka.
1. Kuma xiyimo xa ntirho wa valve kuya hi matirhiselo ya valve eka xitirhisiwa kumbe phayiphi ya phurosese. Xikombiso, xitirhisiwa xa le xikarhi, ntshikelelo wo tirha na mahiselo yo tirha, na swin’wana.
2. Ku kumisisa mpimo wa matirhelo ya ku pfalela ya valve ku ya hi xitirhisiwa xo tirhela, ndhawu yo tirhela eka yona na swilaveko swa mutirhisi.
3. Kuma muxaka wa valve na drive mode kuya hi xikongomelo xa valve. Tinxaka to fana na valve yo tsema, valve yo lawula, valve ya vuhlayiseki, ti valve tin’wana to hlawuleka, na swin’wana na swin’wana Mode yo chayela yo fana na worm wheel worm, gezi, pneumatic, na swin’wana.
4. Hlawula hi ku ya hi tipharamitha ta vito ta valve. Ntshikelelo wa vito na vukulu bya vito bya valve swifanele ku fambelanisiwa na phayiphi ya phurosese leyi vekiweke. Valve yi vekiwa eka phayiphi ya phurosese, hikokwalaho xiyimo xa yona xo tirha xifanele ku fambisana na ku hlawuriwa ka dizayini ya phayiphi ya phurosese. Endzhaku kaloko sisiteme ya standard na ntshikelelo wa vito ra tiphayiphi swikumiwile, ntshikelelo wa nominal wa valve, vukulu bya vito na dizayini ya valve na swipimelo swa vumaki swinga kumiwa. Ti valve tin’wana ti veka vukulu bya vito bya valve kuya hi flow rate kumbe discharge ya valve hi nkarhi lowu ringanyetiweke wa medium.
5. Kuma xivumbeko xa vuhlanganisi bya vuandlalo bya makumu ya valve na phayiphi kuya hi swiyimo swa xiviri swa ntirho na vukulu bya vito bya valve. Kufana na flange, welding, clip kumbe thread, na swin’wana.
6. Kuma xivumbeko na xivumbeko xa muxaka wa valve kuya hi ndzhawu yo veka, ndzhawu yo veka, na vukulu bya vito bya valve. Kufana na valve ya gede ya nhonga ya ntima, valve ya angle globe, valve ya bolo leyi nga cinciki, na swin’wana.
7. Hi ku ya hi swihlawulekisi swa xitirhisiwa xa le xikarhi, ntshikelelo wa ntirho na mahiselo yo tirha, ku ya hi ku hlawuriwa lokunene na loku twalaka ka xikhegelo xa valve na switirhisiwa swa le ndzeni.
Handleka,Tianjin Tanggu Xisirhelelo xa Mati xa Valve Co., Ltd. i thekinoloji ya xiyimo xa le henhla ya elastic seat valve leyi seketelaka mabindzu, swikumiwa i elastic seat wafer butterfly valve, .lug valve ya phaphatani, double flange concentric valve ya phaphatani, double flange eccentric phaphatani valve, ku ringanisela valve, .wafer valve yo kambela tipuleti timbirhi, Y-Strainer na swin’wana. Eka Tianjin Tanggu Water Seal Valve Co., Ltd., hi tinyungubyisa hi ku nyika switirhisiwa swa xiyimo xo sungula leswi fikelelaka swiyimo swa le henhla swa indasitiri. Hi nxaxamelo wa hina wo anama wa tivalvu na switirhisiwa, u nga hi tshemba ku nyika ntlhantlho lowu hetisekeke eka sisiteme ya wena ya mati. Tihlanganisi na hina namuntlha ku dyondza swo tala hi switirhisiwa swa hina na ndlela leyi hi nga ku pfunaka ha yona.
