Inqubo yokukhiqiza kanye nezindawo zokulawula ikhwalithi zamavalvu eglobhu ama-flange ajwayelekile aseShayina

1,Isingeniso

I-valve yeglobu ye-flange ejwayelekile yaseShayina, njenge-valve yamapayipi evamile, isetshenziswa kabanzi ezimbonini ezifana ne-petroleum, amakhemikhali, amandla, kanye ne-metallurgy. Ngenxa yesakhiwo sayo esilula, ukusebenza kahle kokubekwa uphawu, nempilo ende yesevisi, iye yathandwa yimakethe. Kodwa-ke, enqubweni yokukhiqiza, indlela yokuqinisekisa ikhwalithi yama-valve okumisa ama-flange kanye nokuthuthukisa ukuncintisana komkhiqizo sekugxilwe kakhulu kumabhizinisi okukhiqiza. Lesi sihloko sizohlola ukukhiqizwa kwekhwalithi ephezulu kwama-valve embulunga ye-flange ejwayelekile yaseShayina kusuka ezicini ezimbili: inqubo yokukhiqiza kanye nezindawo zokulawula ikhwalithi.

2,Inqubo yokukhiqiza yama-valve eglobhu e-flange ajwayelekile yaseShayina

1. Ukukhetha izinto ezibonakalayo

I-Material iyisici esibalulekile esithinta ikhwalithi yama-valve embulunga ene-flanged. Lapho ukhetha izinto zokwakha, izinto zezingxenye eziyinhloko ezifana nomzimba we-valve, ikhava ye-valve, ne-valve disc kufanele kukhethwe ngokunengqondo ngokusekelwe ezimweni zokusebenza, uhlobo oluphakathi, izinga lokushisa kanye nemingcele yokucindezela kwe-valve. Ngesikhathi esifanayo, ukunakwa kufanele kukhokhwe ekubunjweni kwamakhemikhali, izakhiwo zemishini, ukusebenza kwe-welding nezinye izinkomba zezinto zokuqinisekisa ikhwalithi yayo.

2. I-valve body casting

Umzimba we-valve uyingxenye eyinhloko ephethe ingcindezi ye-valve yembulunga ene-flanged, futhi ikhwalithi yayo ithinta ngokuqondile ukuphepha kokusetshenziswa kwe-valve. Enqubweni yokukhishwa komzimba we-valve, amasu okuphonsa anengqondo kufanele asetshenziswe, njengokuphonsa isihlabathi, ukukhishwa kwegwebu elilahlekile, njll., ukuze kuqinisekiswe ukuthi azikho iziphambeko ezifana nezimbobo zesihlabathi, ama-pores, kanye nokufakwa kwe-slag ngaphakathi komzimba we-valve. Ngasikhathi sinye, kuyadingeka ukulawula ngokuqinile amapharamitha afana nezinga lokushisa kanye nezinga lokupholisa phakathi nenqubo yokukhipha ukugwema ukucindezelwa kokusakaza okuthinta ukunemba kwe-dimensional kanye nezakhiwo zemishini zomzimba we-valve.

3. Ukucutshungulwa komshini

Ukucutshungulwa kwemishini kuyinqubo eyinhloko yokuqinisekisa ukunemba nokushelela kwama-valve embulunga ye-flange. Phakathi nenqubo yokwenza imishini, amathuluzi omshini we-CNC anokunemba okuphezulu nokuqina okuphezulu kufanele akhethwe ukuze kuqinisekiswe ukunemba kwemishini. Ngesikhathi esifanayo, ukusetha okunengqondo kwemingcele yokucubungula, njengejubane lokusika, izinga lokuphakelayo, njll., kungathuthukisa ukusebenza kahle kokucubungula nokunciphisa izindleko. Ngaphezu kwalokho, kubalulekile ukunaka ukulawulwa kwekhwalithi phakathi nenqubo yokucubungula, uhlole ngokucophelela ubukhulu obubalulekile, futhi uqinisekise ukufaneleka komkhiqizo.

4. Ukuhlanganiswa kwe-valve

Ukuhlanganiswa kwama-valve kuyisinyathelo esibalulekile ekuqinisekiseni ukusebenza kokuvala kanye nempilo yesevisi yama-valve eglobhu ane-flanged. Phakathi nenqubo yokuhlanganisa, ukuhlanzeka kwezingxenye kufanele kuqinisekiswe ukugwema ukungcola, amabala kawoyela, nezinye izici ezingase zithinte ukusebenza kokuvala. Ngesikhathi esifanayo, kuyadingeka ukulandela ngokuqinile inqubo yomhlangano ukuze kuqinisekiswe ukunemba okufanelekile kwezindawo zokuvala ezifana nama-valve discs nezihlalo ze-valve. Ngaphezu kwalokho, kufanele kuqashelwe ukukhethwa kwama-gaskets okufaka uphawu, futhi izinto ezifanele ze-gasket kufanele zikhethwe ngokuvumelana nezimo zokusebenza ze-valve ukuze kuthuthukiswe umphumela wokuvala.

5. Inqubo yokushisela

Inqubo yokushisela inomthelela omkhulu emandleni nasekufakweni uphawu kwama-valve embulunga ye-flange. Ngesikhathi senqubo yokushisela, izindlela zokushisela ezifanele kanye nezinto zokwakha kufanele zikhethwe, njenge-argon arc welding, i-arc welding kagesi, njll. weld seam. Ngaphezu kwalokho, ukwelashwa kokushisa kufanele kwenziwe ngemuva kokushiswa ukuze kuqedwe ukucindezeleka kwe-welding futhi kuthuthukiswe izakhiwo zemishini yamajoyini ahlanganisiwe.

3,Amaphuzu abalulekile okulawula ikhwalithi yamavalvu eglobhu e-flange ajwayelekile yaseShayina

1. Ukulawula ikhwalithi yokuklama

Esigabeni sokuklama, kuyadingeka ukucabangela ngokugcwele izici ezifana nezimo zokusebenza kanye nezici eziphakathi kwe-valve, ukwandisa isakhiwo se-valve, futhi uthuthukise ukuphepha nokuthembeka kwe-valve. Ngesikhathi esifanayo, kufanele kuqashelwe ukubala amandla kanye nokubalwa kokusebenza kokuvala kwevalvu ukuze kuqinisekiswe ukuthi ihlangabezana nezidingo zokusetshenziswa phakathi nesikhathi sokuklama.

2. Ukulawulwa kwekhwalithi yezinto ezibonakalayo

Ukulawulwa kwekhwalithi yezinto kuyisisekelo sokuqinisekisa ikhwalithi yama-valve eglobhu ane-flanged. Kudingeka siqinise ukuhlolwa kwezinto ezingavuthiwe, izinto ezisizayo, izinto zokushisela, njll., ukuze siqinisekise ukuthi izinto ezisetshenziswayo zihambisana namazinga kazwelonke nawemboni. Ngesikhathi esifanayo, kufanele kuqashelwe ukuzinza kwekhwalithi yezinto zokwakha ukuze kugwenywe ukungazinzi kwekhwalithi yomkhiqizo okubangelwa ukushintshashintsha kwekhwalithi yezinto.

3. Icubungula ukulawula izinga

Ngesikhathi sokucubungula, kuyadingeka ukulandela ngokuqinile imininingwane yenqubo ukuze uqinisekise ukunemba kwemishini. Qinisa ukulawulwa kwekhwalithi yezinqubo ezibalulekile, njengokusakazwa komzimba we-valve, ukucubungula ngomshini, ukushisela, njll., ukuqinisekisa ikhwalithi yomkhiqizo. Ngesikhathi esifanayo, ukugcinwa nokugcinwa njalo kufanele kwenziwe kumishini ukuze kuthuthukiswe ukunemba kwayo nokuqinisekisa ikhwalithi yomkhiqizo.

4. Ukulawulwa kwekhwalithi yomhlangano

Ukulawulwa kwekhwalithi yomhlangano kuyisihluthulelo sokuqinisekisa ukusebenza kokuvala kanye nempilo yesevisi yama-valve okumisa ama-flange. Phakathi nenqubo yomhlangano, kuyadingeka ukulandela ngokuqinile inqubo yomhlangano ukuze kuqinisekiswe ukuhlanzeka nokunemba okufanele kwezingxenye. Qinisa ukuhlolwa kwendawo yokuvala ukuze uqinisekise ukuthi akukho miklwelwe, ukuguga noma okunye ukonakala endaweni yokuvala. Ngaphezu kwalokho, kufanele kuqashelwe ekukhethweni nasekufakweni kwama-gaskets ukuze kuthuthukiswe umphumela wokuvala.

5. Ukulawulwa kwekhwalithi yokuhlola

Ukuhlola kuyisinyathelo esibalulekile sokuqinisekisa izinga lama-valve embulunga ane-flanged. Kudingeka siqinise ukuhlolwa kwemikhiqizo eqediwe futhi ecishe iqedwe ukuze siqinisekise ukuthi iyahlangabezana namazinga kazwelonke nawemboni. Ngesikhathi esifanayo, kufanele kuqashelwe ukuqeqeshwa kwabasebenzi abahlolayo ukuze bathuthukise izinga labo lokuhlola futhi bagweme izinkinga zekhwalithi yomkhiqizo ezibangelwa izici zomuntu.

4,Isiphetho

Inqubo yokukhiqiza kanye nezindawo zokulawula ikhwalithi zamavalvu embulunga ye-flange ejwayelekile yaseShayina kuwukhiye wokuqinisekisa ikhwalithi yomkhiqizo. Ngokwenza kahle ukuklama, ukukhetha izinto ezisezingeni eliphezulu, ukulawula ngokuqinile ukucutshungulwa kanye nenqubo yokuhlanganisa, nokuqinisa ukuhlolwa, izinga lama-valve embulunga ye-flange lingathuthukiswa futhi nokuncintisana komkhiqizo kungathuthukiswa. Amabhizinisi kufanele aqhubeke ehlola ubuchwepheshe obusha nezinqubo, anikeze abasebenzisi izinga eliphezulu nemikhiqizo enokwethenjelwa, futhi abambe iqhaza ekuthuthukisweni kwemboni yamavalvu yaseChina.
