Umahluko kwizinto eziphathekayo
Intsimbi eyenziweyo:
Insimbi eyenziweyo iveliswa ngokufudumeza iibhilidi zetsimbi kunye nokubumba phantsi koxinzelelo oluphezulu. Le nkqubo iphucula ukwakheka kweenkozo, okukhokelela kumandla omatshini aphezulu, ukuqina, kunye nokuchasana noxinzelelo oluphezulu / ubushushu obungqongileyo. Amanqaku aqhelekileyo abandakanyaI-ASTM A105 (intsimbi yekhabhoni)kwayeI-ASTM A182 (intsimbi engenasici).
Intsimbi yentsimbi:
Intsimbi etyhidiweyo yenziwa ngokugalela intsimbi etyhidiweyo kwimibundo. Ngelixa indleko esebenzayo kwiimilo eziyinkimbinkimbi, inokubonisa i-porosity okanye ukungahambelani, ukunciphisa ukusetyenziswa kwayo kwiimeko ezinzima. Amanqaku aqhelekileyo aquka i-ASTM A216 WCB (intsimbi yekhabhoni) kunye ne-ASTM A351 CF8M (intsimbi engenanto).
Iiyantlukwano eziphambili phakathi kweValve yentsimbi eyenziweyo kunye neValve yentsimbi yeCast
| Ipharamitha | Iivalvu zeNtsimbi ezenziweyo | Iivalve zeNtsimbi |
| Ubungakanani Uluhlu | Incinci (DN15–DN200, ½”–8″) | Enkulu (DN50–DN1200, 2″–48″) |
| Ixabiso loxinzelelo | Phezulu (Udidi 800–4500) | Phakathi (Udidi 150–600) |
| Ubushushu | -29°C ukuya kuma-550°C | -29°C ukuya kuma-425°C |
| Usetyenziso | Imibhobho yoxinzelelo oluphezulu, iindawo zokucoca | Iinkqubo eziphantsi/zoxinzelelo oluphakathi, amanzi |
Izahlulo zeValve
Iivalvu zeNtsimbi ezenziweyo
1. Iivalvu zeSango leNsimbi elibunjiweyo (iKlasi 800): Uyilo olubambeneyo lokwahlulwa koxinzelelo oluphezulu kwiinkqubo zeoyile / zegesi.
2. Iivalvu zeGlobhu yentsimbi eyenziweyo: Ulawulo oluchanekileyo lokuhamba kwamanzi kwiinkonzo zomphunga okanye iikhemikhali.
3. Iivalvu zeNtsimbi ezibunjiweyo: Thintela ukubuyela umva kwii-compressor okanye iimpompo (iintlobo ze-swing / lift).
4. Iivalvu zeBhola yeNsimbi eyenziweyo: Ukuvalwa ngokukhawuleza kwiKlasi ye-800 yemibhobho ye-hydrocarbon.
Iivalve zeNtsimbi
1. Iivalvu zeSango lentsimbi yokuCasa (Udidi 150–300): Ukwahlulwa kolwelo oluninzi kunyango lwamanzi.
2. Cast Steel Globe iivalvu: Ukulawulwa kokuhamba ngokubanzi kwiinkqubo zeHVAC.
3. I-Cast Steel Check Valves: Izisombululo zexabiso eliphantsi kwiinkonzo ezingabalulekanga.
Kutheni KhethaIklasi ye-800 yeeValufa zeNtsimbi ezibunjiweyo
Iklasi ye-800 i-valve yentsimbi ekhandiweyo imelana noxinzelelo ukuya kwi-bar ye-1380 (20,000 psi) kwi-38 ° C, ibenza ukuba balungele:
- Izixhobo ze-oyile ezikude nonxweme
- Imigca yomphunga wobushushu obuphezulu
-Amaziko okulungisa iHydrojeni
Ukuqukumbela
Iivalvu zentsimbi ezenziweyozigqwesa kwiindawo ezinoxinzelelo oluphezulu ngenxa yolwakhiwo lwazo oluqinileyo, ngelixa iivalvu zentsimbi zibonelela ngezisombululo zezoqoqosho kwiinkqubo ezinkulu, eziphantsi koxinzelelo. Ukukhetha uhlobo oluchanekileyo kuxhomekeke kwiimfuno zokusebenza, uhlahlo lwabiwo-mali, kunye nemigangatho yoshishino efana ne-ASME B16.34.
