Umtsetfo wekukhetsa ivalve
I valve lekhetsiwe kufanele ihlangabetane naletimiso letisisekelo letilandzelako.
(1) Kuphepha kanye nekwetsembeka kwe-petrochemical, sikhungo semandla, tinsimbi kanye naletinye timboni kudzinga kusebenta lokuchubekako, lokuzinzile, kwemjikeleto lomudze. Ngakho-ke, valve letidzingekako kufanele kube kwetsembeka lokusezingeni leliphakeme, sici lesikhulu sekuphepha, angeke kubangele kuphepha lokukhulu kwekukhicita kanye nekulimala kwemuntfu sicu ngenca yekwehluleka kwevalve, kuhlangabetana netidzingo tekusebenta kwemjikeleto lomudze kwedivayisi, kanye nekukhicita lokuchubekako kwemjikeleto lomudze kuyinzuzo.
(2) Kuhlangabetana netidzingo tenchubo yekukhicita valve kufanele uhlangabetane nekusetjentiswa kwemkhawulo, umfutfo wekusebenta, lokushisa lokusebenta kanye netidzingo tekusebentisa, lokuphindze kube tidzingo letisisekelo tekukhetsa valve. Uma sidzingo valve overpressure indima yekuvikela, kukhishwa lokungetulu kwemkhatsi, kufanele ukhetse valve yekuphepha, valve lephuphumako, sidzingo sekuvimbela inchubo yekusebenta yekugeleta emuva lokusemkhatsini, kufanele usebentise valve yekuhlola, sidzingo sekucedza ngekuzenzakalela iphayiphi yemphunga kanye nemishini ye-condensate, umoya kanye nalokunye lokungakhoni condensing igesi, kanye nekuvimbela i-dracain es kufanele i-dracain es. Ngekwengeta, uma lendzawo lesemkhatsini igcoba, tintfo letinhle tekumelana nekugcola kumele tikhetfwe.
(3) Ngemuva kwekusebenta, kufakwa, kuhlola (kugcinwa) kulungiswa kwevalve, umsebentisi kufanele akhone kubona kahle sicondziso sevalve, timphawu tekuvula, timphawu tekukhombisa, kulula ngesikhatsi futsi ngekuciniseka kubhekana nemaphutsa lehlukahlukene laphutfumako. Ngesikhatsi lesifanako, isakhiwo seluhlobo lwevalve lekhetsiwe kufanele sibe khona lapho kungenteka khona ishidi isilinda, kufakwa, kuhlola (kugcinwa) kulungisa elula.
(4) Umnotfo Endzabeni yekuhlangabetana nekusetjentiswa lokujwayelekile kwemaphayiphi enchubo, emavalvu lanetindleko letiphansi tekukhicita kanye nesakhiwo lesilula kufanele akhetfwe ngendlela lekhonakalako ngayo kute kuncishiswe tindleko tedivayisi, kugwenywe kucitsa tintfo letiluhlata tevalvu kanye nekunciphisa tindleko tekufakwa kwemavalvu kanye nekunakekelwa esigabeni sakamuva.
Tinyatselo tekukhetsa ivalve
Kukhetsa emavalvu kuvame kulandzelela letinyatselo letilandzelako,
1. Tfola simo sekusebenta valve ngekuya kusetjentiswa valve kudivayisi noma inqubo pipeline. Sibonelo, kusebenta medium, kusebenta umfutfo kanye lokushisa lokusebenta, njll.
2. Tincume lizinga lekusebenta kwekuvala kwevalve ngekuya kwendlela yekusebenta, indzawo yekusebenta kanye netidzingo temsebentisi.
3. Tincume uhlobo valve kanye drive imodi ngekuya kwenjongo valve. Tinhlobo letifana na .Ivalvu yevivane lecinile, Ivalve yesango lehleti ngerabha,Ivalvu yesango lehleti ngerabha, valve ibhalansi, njll Imodi yekushayela njengesibungu isondo sibungu, kagesi, pneumatic, njll.
4. Khetsa ngekuya kwemikhawulo lebitwako yevalve. Umfutfo lobitwako kanye nebukhulu lobubitwako bevalve kutawuhambisana neliphayiphi lenchubo lelifakiwe. Le valve ifakwe ephayiphini lenchubo, ngako-ke simo sayo sekusebenta kufanele sihambisane nekukhetsa umklamo wephayiphi lenchubo. Ngemuva kwekutsi luhlelo lolujwayelekile kanye nekucindzeteleka kwemaphayiphi lokubitwako kuncunywe, umfutfo wekubita kwevalve, bukhulu lobubitwako kanye nekwakhiwa kwevalve kanye nemazinga ekukhicita kungancunywa. Lamanye emavalvu ancuma linani lelibitwako levalve ngekuya kwelizinga lekugeleza noma kukhishwa kwevalve ngesikhatsi lesilinganisiwe sesikhatsi lesisemkhatsini.
5. Tincumo ifomu uxhumano valve ekugcineni ebusweni kanye iphayiphi ngekuya timo langempela ukusebenza kanye nominal usayizi valve. Njenge-flange, kushisela, i-wafer noma intambo, njll.
6. Tfola isakhiwo kanye nesimo seluhlobo lwevalve ngekuya kwesikhundla sekufakwa, sikhala sekufakwa, kanye nebukhulu lobubitwako bevalve. Njenge valve yesango lemnyama, sicu lesikhuphukakoIvalvu yesango, valve yebhola lecinile, njll.
7. Ngekuya kwetimphawu letisemkhatsini, umfutfo wekusebenta kanye nekushisa lokusebenta, kukhetsa kahle futsi ngendlela lenengcondvo i-valve.
E-Tianjin Tanggu Water Seal Valve Co., Ltd., siyatigcabha ngekuniketa imikhicito yesigaba sekucala lehlangabetana nemazinga laphakeme embonini. Ngeluhlu lwetfu lolubanti lwemavalvu kanye netimphahla, ungasetsemba kutsi sikunikete sisombululo lesiphelele seluhlelo lwakho lwemanti. Xhumana natsi namuhla kute utfole kabanti ngemikhicito yetfu nekutsi singakusita njani.
