Kungani kukhethwa kwe-valve valve kuhlale kunezingibe?

Kungani kukhethwa kwe-valve valve kuhlale kunezingibe? Lezi 5 'Izicupho Ezingabonakali' ziphindwe kabili izindleko zobunjiniyela!

Ezinhlelweni zamapayipi ezimboni,ama-gang valvesamadivayisi abucayi ama-cutoff. Ukukhetha okungalungile kungaholela ekubambeni okujwayelekile nokusebenza okusebenzayo, futhi ezimweni ezinzima, ezingozini zokuphepha, futhi kubiza kakhulu iphrojekthi yonke. Kodwa-ke, ngokoqobo, ngaphezu kwama-60% amanga okuhluleka kwesango, amaphutha aphansi "ngesikhathi sokukhetha. Kungani ama-valves e-Gate anamapharamitha afanayo afanayo empeleni anokusebenza okuhlukile kakhulu? Le ndatshana idalula izingibe ezi-5 ezinganakwa ukukusiza ugweme izingibe.

Isicupho 1: Ingcindezi yokuqothuka (PN) ilebheli ngamanga, futhi ukumelana kwengcindezi enganele kungaholela emiphumeleni emibi

Ingcindezi yokuqothuka yipharamitha ebalulekile yama-valves valves, kepha abanye abakhiqizi bavame ukusika amakhona ngezinto zokwakha ukuze banciphise izindleko. Ukwenza isibonelo, nge-valive valve nge-pn16 ye-ominal pn16, uma umzimba we-valve wehlise kusuka ku-WCB (I-Carbon Steel) ku-HT250 (Grey Cast Iron), ukumelana kwayo okungokoqobo kuzokwehla kakhulu kusuka ku-16MPA kuya ku-6MPA. Ibhizinisi elithile lamakhemikhali likhethwe ngephutha lolu hlobo lwe-valve valve yamapayipi aphezulu okucindezela, futhi ngemuva kwezinyanga ezi-3 zokusebenza, umzimba we-valve uqhume, okuholela ekulahlekelweni okuqondile kwe-800000 Yuan. Ukhiye wokukhetha: Umkhiqizi uyadingeka ukuhlinzeka ngombiko wokuhlola izinto ezibonakalayo futhi uqinisekise ukuhambisana phakathi kwenani le-PN kanye nezinto zokwakha umzimba we-valve, ikhava ye-valve, nesiqu se-valve.

Isicupho 2: Ukufakwa kokuvalwa kokubekwa uphawu komhlaba, ukuvuza kuba yinto evamile

Ukusebenza kokubekwa uphawu kwama-valves wesango kuya ngokuhambisana phakathi kwezinto zokubopha komhlaba kanye nezimo zokusebenza, kepha ukukhetha kuvame ukunganakwa. Isibonelo, ama-valves wesango elivalwe kanzima Isitshalo esithile sokwelashwa sendle sendle lapho sisebenzise ama-valve athambile avaliwe amapayipi wendle aqukethe i-sediment. Kungakapheli inyanga eyodwa nje, indawo ebekelwe uphawu yayigqokwa futhi yavuza, yaphoqa ukushintshwa ngama-valve e-hard avaliwe ukuxazulula inkinga. Ukhiye wokukhetha: Chaza ngokucacile ukwakheka, izinga lokushisa, kanye nengcindezi ye-medium, bese ubeka phambili ukukhetha ama-valves wesango eline-rangerance raterance ekhulu kunenani lomkhawulo wokusebenza.

Isicupho 3: Ukubuyekezwa kabusha kwesakhiwo se-valve squem, inkinga phakathi kokusebenza nokugcinwa

Isakhiwo se-stemama-gang valvesIhlukaniswe ngesiqu esivulekile nesiqu esifihliwe, futhi ukukhethwa kufanele kususelwe esikhaleni sokufaka kanye nokuhlaziywa kwemali. Ama-grad stem Gate Valves athambekele ekuqothulweni kothuli kanye nokugqwala ngenxa yeziqu ze-valve eziveziwe, kepha isikhundla se-valve stem singabonakala ngqo ngesikhathi sokulungiswa; I-Valve efihliwe ye-STEM Gate Valve inesakhiwo esihlangene futhi ilungele isimo esilinganiselwe sesikhala, kepha uma uphawu luhluleka, lonke i-valve lizohlukaniswa. Ngenxa yokuntuleka kokucatshangelwa kokulungiswa kwemali, iphrojekthi ethile engaphansi komhlaba yakhetha ama-valuefied galves afihliwe emihubheni emincane, edinga ukudilizwa kwamapayipi ngesikhathi sokulungisa kamuva. Ukhiye wokukhetha: Isikhala esanele nokulungiswa okuvama kudingeka ukukhetha isigxobo esibonakalayo; Isikhala silinganiselwe futhi ukusebenza isikhathi eside kudinga ukusetshenziswa kwezigxobo ezifihliwe.

Isicupho 4: Izindlela zokushayela ezenziwe nge-mismated, ukungalingani phakathi kokusebenza kahle nezindleko

Ama-valves e-Manual Gate anezindleko eziphansi, kepha izinzuzo ezizenzakalelayo ze-Electric Gate Valves zivame ukungabukelwa phansi. Isibonelo, ezinhlelweni zokuvikela umlilo ezidinga ukulawulwa kude, ama-value we-Manual Gate adinga ukusebenza kwe-Manual On-Site futhi abe nezikhathi zokuphendula kancane; I-Valve ye-Electric Gate ingaxhunyaniswa ohlelweni lokuxhumana ngomlilo futhi ingavulwa futhi ivalwe ngemizuzwana emi-3. Isakhiwo sezentengiselwano esake sasetshenziswa ama-valves e-Manual Galves ukusindisa izindleko, kepha ngesikhathi somlilo, abasebenzi abakwazanga ukufika endaweni yesehlakalo ngesikhathi sokuvala ama-valve, okwenza umlilo usakaze. Ukhiye wokukhetha: Yenza izinqumo eziphelele ezisekelwe kwizidingo zokulawula (Manual / Electric / pneumatic), isivinini sokuphendula, kanye nesabelomali.

Isicupho 5: Ukuqinisekiswa Kwezimboni 'Kulahlekile', ikhwalithi ayiqinisekisiwe

Ama-gang valvesUdinga ukuqinisekiswa ngokuya ngamazinga afana ne-API 6D ne-GB / T 12234, kepha amanye amafektri amancane ashiya izinyathelo zokuhlola eziphambili zokuthumela okusheshayo. Isibonelo, ama-varo valves angakaze athathe izivivinyo zokushisa okushisa okuphansi athambekele ekuqhekekeni kwe-brittle endaweni ye--20 ℃; I-Valve valve engazange idlulise isivivinyo sesawoti sokufafaza usawoti ivela ngemuva kwezinyanga ezintathu endaweni yasolwandle. Ukhiye wokukhetha: Umkhiqizi uyadingeka ukuhlinzeka ngezitifiketi zokuqinisekisa futhi uqinisekise idatha ebalulekile efana nokushisa okushisa, ingcindezi, kanye nokuphikiswa kokugqwala embikweni wokuhlola.

ISIPHETHO Ukukhetha okukodwa okulungile kunganweba impilo yenkonzo yama-valves ama-galves ngezikhathi ezi-3-5 futhi kunciphise izindleko zokulungisa ngaphezulu kwama-50%. Khumbula: Ukubuza "Ngabe kufanelekile ngenxa yezimo zami zokusebenza?" Lapho ukhetha ungcono kunokuyilungisa izikhathi eziyishumi ngemuva kwalokho!
