Umahluko kwizinto eziphathekayo
Intsimbi Eyenziweyo:
Intsimbi eyenziweyo iveliswa ngokufudumeza iibhilethi zentsimbi nokuzenza zibe mdaka phantsi koxinzelelo oluphezulu. Le nkqubo iphucula ulwakhiwo lweenkozo, nto leyo ebangela amandla aphezulu oomatshini, ukuqina, kunye nokumelana neemeko zoxinzelelo/ubushushu obuphezulu. Amanqaku aqhelekileyo aquka:I-ASTM A105 (intsimbi yekhabhoni)kwayeI-ASTM A182 (intsimbi engagqwaliyo).
Intsimbi Ephosiweyo:
Intsimbi ephothiweyo yenziwa ngokugalela intsimbi enyibilikisiweyo kwiimolds. Nangona ingabizi kakhulu kwiimo ezintsonkothileyo, isenokubonisa ukuvuleka okanye ukungangqinelani, nto leyo ethintela ukusetyenziswa kwayo kwiimeko eziqatha. Iindidi eziqhelekileyo ziquka i-ASTM A216 WCB (intsimbi yekhabhoni) kunye ne-ASTM A351 CF8M (intsimbi engagqwaliyo).
Umahluko oPhambili phakathi kweValve yeNsimbi eQhekeziweyo kunye neeValve zeNsimbi eziQhekeziweyo
| Ipharamitha | Iivalvu zentsimbi ezibunjiweyo | Iivalvu zentsimbi eyenziweyo |
| Uluhlu lobungakanani | Encinci (DN15–DN200, ½”–8″) | Enkulu (DN50–DN1200, 2″–48″) |
| Uvavanyo loxinzelelo | Phezulu (Iklasi 800–4500) | Phakathi (iKlasi 150–600) |
| Ubushushu | -29°C ukuya kuma-550°C | -29°C ukuya kwi-425°C |
| Izicelo | Iipayipi ezinoxinzelelo oluphezulu, iifektri zokucoca | Iinkqubo zoxinzelelo oluphantsi/oluphakathi, amanzi |
Ulwahlulo lweeValve
Iivalvu zentsimbi ezibunjiweyo
1. Iivalvu zeSango leNsimbi eziBunjiweyo (iKlasi 800): Uyilo oluncinci lokwahlukanisa izinto ezinoxinzelelo oluphezulu kwiinkqubo zeoyile/zegesi.
2. Iivalvu zeGlobe zeNtsimbi eziBunjiweyo: Ulawulo oluchanekileyo lokuhamba kwamanzi kwiinkonzo zomphunga okanye zeekhemikhali.
3. Iivalvu zokujonga zentsimbi eyenziweyo: Nqanda ukubuya kwamanzi kwiicompressor okanye iimpompo (iintlobo zokujika/zokuphakamisa).
4. Iivalvu zeBhola zeNsimbi eziQhelekileyo: Ukuvalwa ngokukhawuleza kwimibhobho ye-hydrocarbon yeKlasi 800.
Iivalvu zentsimbi eyenziweyo
1. Iivalvu zeSango leNtsimbi eyenziwe ngeCast (iKlasi 150–300): Ukwahlulwa kolwelo oluninzi xa kucocwa ngamanzi.
2. Iivalvu zeGlobe zeNtsimbi eziphosiweyo: Ulawulo oluqhelekileyo lokuhamba kwamanzi kwiinkqubo ze-HVAC.
3. Iivalvu zokujonga zentsimbi eyenziwe ngesinyithi: Izisombululo ezingabizi kakhulu kwiinkonzo ezingezizo ezibalulekileyo.
Kutheni UkhethaIivalvu zeNsimbi eziQhelekileyo zeKlasi 800
Iivalvu zentsimbi ezenziwe nge-Class 800 zimelana noxinzelelo olufikelela kwi-1380 bar (20,000 psi) kwi-38°C, nto leyo eyenza ukuba zilungele oku kulandelayo:
- Izixhobo zeoyile zaselwandle
- Imigca yomphunga enobushushu obuphezulu
- Izityalo zokucubungula i-hydrogen
Isiphelo
Iivalvu zentsimbi ezenziweyoZiyaphumelela kwiindawo ezinoxinzelelo olukhulu ngenxa yokwakhiwa kwazo okuqinileyo, ngelixa iivalvu zentsimbi ezidityanisiweyo zibonelela ngezisombululo ezingabizi kakhulu kwiinkqubo ezinkulu nezinoxinzelelo oluphantsi. Ukukhetha uhlobo olufanelekileyo kuxhomekeke kwiimfuno zokusebenza, uhlahlo lwabiwo-mali, kunye nemigangatho yoshishino efana ne-ASME B16.34.
