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 zasolwandle
- Imigca yomphunga enobushushu obuphezulu
- Izityalo zokucubungula i-hydrogen
Isiphelo
Iivalvu zentsimbi ezenziweyoZiyaphumelela kwiindawo ezixinezelekileyo ngenxa yokwakhiwa kwazo okuqinileyo, ngelixa iivalvu zentsimbi ezidityanisiweyo zibonelela ngezisombululo ezingabizi kakhulu kwiinkqubo ezinkulu nezixinezelekileyo. Ukukhetha uhlobo olufanelekileyo kuxhomekeke kwiimfuno zokusebenza, uhlahlo lwabiwo-mali, kunye nemigangatho yeshishini efana ne-ASME B16.34.
