Iivalvu zeSango leNsimbi eziBunjiweyo: Izisombululo eziSebenza ngokuPhezulu kwiMizi-mveliso eBangayo

Iivalvu zesango lentsimbi eziqingqiweyo zizinto ezibalulekileyo kwiinkqubo zemibhobho yemizi-mveliso, ezenzelwe ukujongana noxinzelelo olugqithisileyo, amaqondo obushushu, kunye neendawo ezingcolisayo. Eli nqaku lihlola ukuba zeziphi iivalvu zesango lentsimbi eziqingqiweyo, izibonelelo zazo, usetyenziso, kunye neenkcukacha zobugcisa—kunye nesizathu sokukhetha.Abavelisi beevalvu zesango lentsimbi eyenziweyo yaseTshayinaiqinisekisa ukuthembeka nokusebenza kakuhle kweendleko.

Yintoni iValve yeSango leNtsimbi eQhekethiweyo

A ivalvu yesango lentsimbi eyenziweyoluhlobo lwevalvu eyenziwe ngokubumba, inkqubo ecinezela kwaye ibumbe intsimbi phantsi kobushushu obuphezulu kunye noxinzelelo. Le ndlela iphucula ukuqina kwesakhiwo sentsimbi, yenza ivalvu ibe namandla, ihlale ixesha elide, kwaye imelane nokuvuza xa ithelekiswa nezinye iindlela ze-cast.

Izinto eziphambili ziquka isango, isiqu, kunye nomzimba omile okwe-wedge, ezenzelwe ukulawula ukuhamba kwamanzi ngokuchanekileyo kwiinkqubo ezixinezelekileyo kakhulu.

Iingenelo zeeValve zeSango leNtsimbi eziBunjiweyo

1. Amandla Aphezulu NokuqinaIntsimbi eqingqiweyo inika amandla aphezulu okutyhala, ilungele ukusetyenziswaIivalvu zesango lentsimbi eyenziwe nge-Class 800(ulinganiswe nge-800 PSI).

2. Ukusebenza Okungenazivuthululo: Ukuvalwa okuqinileyo kunciphisa ukukhutshwa kwegesi kwiindawo ezibalulekileyo.

3. Ukumelana nobushushu obuphezulu: Imelana namaqondo obushushu afikelela kwi-1,000°F (538°C).

4. Ukumelana nokugqwala: Iyahambelana nomphunga, ioyile, igesi, kunye neekhemikhali ezirhabaxa.

5. Unxibelelwano Oluguquguqukayo: Ifumaneka kwiI-SW (i-Socket Weld), I-BW (i-Butt Weld)kunyeIivalvu zesango lentsimbi eyenziwe nge-NPTukuze kufakelwe izinto eziguquguqukayo.

Usetyenziso lweeValve zeSango leNtsimbi eziBunjiweyo

Iivalvu zesango lentsimbi ezibunjiweyo zisetyenziswa kakhulu kwezi:

- Imibhobho yeoyile negesi

- Izityalo zokuvelisa umbane

- Iiyunithi zokucubungula iikhemikhali

- Iinkqubo zomphunga ezinoxinzelelo oluphezulu

- Iindawo zokucoca kunye nezakhiwo ze-petrochemical

Ubungakanani obuqhelekileyo buqukaIivalvu zesango lentsimbi eyenziwe ngentsimbi eyi-1/2 intshikwiinkqubo ezixineneyo kunyeIivalvu zesango zentsimbi ezibunjiweyo eziyi-1 1/2kwiipayipi ezinkulu.

Iinkcukacha zobugcisa: Uxinzelelo, Ubungakanani kunye nobushushu

- Uvavanyo loxinzelelo: Ukusuka kwiKlasi ye-150 ukuya kwiKlasi yama-2500, kunyeIivalvu zesango lentsimbi eyenziwe nge-Class 800kuba lukhetho oludumileyo lwezicelo ezinzima.

- Ubungakanani: Ubungakanani obuqhelekileyo buqala kwi-1/2″ ukuya kwi-24″, kunye neendlela ezenziwe ngokwezifiso ezikhoyo.

- Uluhlu lobushushu: -20°F ukuya kwi-1,000°F (-29°C ukuya kwi-538°C), kuxhomekeke kwiindidi zezinto ezifana ne-ASTM A105 okanye i-A182.

Kutheni Ufanele Ukhethe Abavelisi BeValve Yesango Lentsimbi YaseTshayina

I-China ivele njengenkokeli yehlabathi kwimveliso yeevalvu, inika:

1. Amaxabiso Asebenza Kakuhle Ngeendleko: UkhuphiswanoAmaxabiso evalvu yesango lentsimbi eyenziweyongaphandle kokubeka umgangatho esichengeni.

2. Amandla okuvelisa aPhambili: Izibonelelo zanamhlanje zokwenziwa nokuvavanywa ngokuchanekileyo.

3. Ukwenziwa ngokwezifisoIzisombululo ezenzelwe ubungakanani (umz.,Ivalvu yesango yentsimbi eyi-1 1/2 eyenziwe ngomgunyathi), udidi loxinzelelo, kunye neentlobo zoqhagamshelo.

4. Iziqinisekiso zeHlabathi: Ukuthobela imigangatho ye-API, i-ANSI, kunye ne-ISO.

UkukhokelaIifektri zevalvu zesango lentsimbi eyenziweyo yaseTshayinadibanisa ubuchule kunye nemveliso enokwandiswa, uqinisekise ukuhanjiswa ngexesha elifanelekileyo kwee-odolo ezinkulu.

Iivalvu zeSango leNsimbi eyenziwe ngeSW, BW, kunye neNPT

- I-SW (i-Socket Weld): Ilungele iinkqubo ezinobukhulu obuncinci, ezinoxinzelelo oluphezulu.

- I-BW (i-Butt Weld): Isetyenziswa kwiinethiwekhi zemibhobho ezihlala zihleli, ezisemgangathweni ophezulu.

- I-NPT (Umsonto weSizwe wePipe): Ifanelekile kwiimeko ezinoxinzelelo oluphantsi, ezilula ukuyifaka.

Isiphelo

Iivalvu zesango lentsimbi ezibunjiweyo zibalulekile kumashishini abeka phambili ukhuseleko nokusebenza kakuhle phantsi kweemeko ezinzima.I-valve yesango lentsimbi eyenziwe nge-Class 800, incinci1/2 intshiiimodeli, okanye uyilo lwe-BW/SW olulungiselelwe wena,Abavelisi beevalvu zesango lentsimbi eyenziweyo yaseTshayinaukubonelela ngomgangatho ongenakuthelekiswa nanto kunye nokufikeleleka.
