Intshayelelo yokusetyenziswa, eyona nto iphambili kunye neempawu zesakhiwo se-valve ye-wafer

Jonga i-valve Ibhekisa kwivali evula ngokuzenzekelayo kwaye ivale i-valve ixhomekeke ekuhambeni kwendawo ephakathi ukuthintela ukubuyela umva kwephakathi, okwabizwa ngokubaJonga i-valve, ivalve enye, i-valve ephindaphindwe kwaye ivutha ivalve engasemva. IJonga i-valveYiveli eyenzekelayo enomsebenzi ophambili kukuthintela ukubuyela umva kwe-Preum, ukujikeleza okungalunganga kwempompo kunye nokuqhuba, kunye nokukhutshwa kwephakathi kwesikhongozeli. Jonga iiValves nazo zinokusetyenziswa kwimigca yokubonelela ngeenkqubo ezincedisayo apho uxinzelelo lunganyuka ngaphezulu koxinzelelo lwenkqubo.

1.TUsebenzisa i-valve yokutyikitywa ye-wafer.

IJonga i-valve ifakiwe kwinkqubo ye-piholil, kwaye umsebenzi wayo ophambili kukuthintela ukubuyela umva kwephakathi. IJonga i-valveNgaba i-valve ezenzekelayo evulwa kwaye ivaliwe ngokuxhomekeke kwingcinezelo ephakathi.Ivalve ye-wafer ilungele uxinzelelo lwe-PN1.0MPA ~ 42.0MPA, iklasi150 ~ 25000; I-DN15 ~ 1200mm, NPS1 / 2 ~ 48; I-backfloum ephakathi. Ngokukhetha izixhobo ezahlukeneyo, zinokusetyenziswa kumajelo eendaba ezahlukeneyo ezinje ngamanzi, i-Steam, ioyile, i-nitric acid, i-acetic acid, i-oxic acid i-acid ephakathi ne-oxiditye ephakathi kunye ne-aciditye eqinileyo.

2.TUbambisa iivalve ye-wafer:

Kukho i-carbon yentsimbi, i-steel yeqondo eliphantsi lentsimbi (F51 / F516), i-titanium, i-titanium, i-SS316, i-SS316, i-SS316, i-SS316, i-SS316, i-SS316, i-SS216, i-SSTLY, i-distelloy kunye nezinye izinto zentsimbi.

I-3. Iimpawu zesakhiwo zeivalve ye-wafer:

A. Ubude bobugcisa bufutshane, kwaye ubude bayo bobubanzi buyi-1/4 ~ 1/8 ye-valve yemveli

B. Ubungakanani obuncinci kunye nobunzima bokukhanya, ubunzima bayo buyi-1/4 ~ 1/20 ye-valve yendabuko yefuthe

C. I-CLA ye-valve ivala ngokukhawuleza kwaye i-hammer yamanzi incinci incinci

D. Zombini imibhobho ethe tyaba okanye imibhobho ethe nkqo inokusetyenziswa, kulula ukuyifaka

E. Ijelo lokuhamba ligudile kwaye ukuchasana nokunganyangeki kuncinane

F. Inyathelo elibuthathaka kunye nentsebenzo elungileyo yokutywina

G. I-dipc ye-Palve ifikile kwaye ifuthe lokuvala lincinci

H. Isakhiwo esipheleleyo ilula kwaye icekeceke, kwaye imilo intle

I. Ubomi obude bobomi kunye nentsebenzo ethembekileyo

4.TUphoso oluqhelekileyo lwevalve yetsheki zezi:

A. Idiski yeValve yaphukile

Ingcinezelo ye-Preimu ngaphambi nasemva kweValve yetsheki ikwimeko esondeleyo kwibhalansi kwaye ithengiwe ". Idiski ye-valve ihlala ithethwa ngesihlalo sevali, kunye ne-vallve ye-vall ye-Brittles (njenge-iron yentsimbi, ubhedu, njl njl.) Yaphukile. Indlela yokuthintela kukusebenzisa ivalve yokujonga nge-disc njengento ephilayo.

B. Ukubetha komntu ophakathi

Umhlaba wokutywina wonakalisiwe; Ukungcola kuyabanjiswa. Ngokulungisa umphezulu wokutywina kunye nokucoceka, i-backflow inokuthintelwa.
