Ungawalungisa kanjani ama-valve avuzayo?

Uma i-valve ivuza, okokuqala sidinga ukuthola imbangela yokuvuza kwe-valve, bese sakha uhlelo lokulungisa i-valve ngokwezizathu ezahlukene.Okulandelayo yizimbangela ezivamile zokuvuza kwe-valve nezixazululo.

1.Ukuvuza komzimba kanye nebhonethi

Isizathu:

①Ikhwalithi yokulingisa ayikho phezulu, futhi umzimba nebhonethi kunokushiyeka njengamabhamuza, ukwakheka okuxekethile nokufakwa kwe-slag;

② qhwa ukuqhekeka;

③ I-welding engalungile, kukhona iziphambeko ezifana nokufakwa kwe-slag, okungeyona i-welding, ukuqhekeka kwengcindezi, njll.;

④I-valve yensimbi yolimele yonakele ngemva kokushaywa into esindayo.

Indlela yokunakekela:

①Thuthukisa ikhwalithi yokulingisa, futhi wenze ukuhlolwa kwamandla ngokuhambisana ngokuqinile nemithetho ngaphambi kokufaka;

②Kumavalvu asebenza ngezinga lokushisa eliphansi elifana no-0°C noma ngaphansi kuka-0°C, ukugcinwa kokushisa noma ukuxutshwa kufanele kwenziwe, futhi amavalvu angasasebenzi kufanele akhishwe emanzini anqwabelene;

③ Umthungo wokushisela womzimba we-valve kanye nebhonethi eyakhiwe nge-welding izokwenziwa ngokuhambisana nemithetho efanele yokusebenza kwe-welding, futhi ukutholakala kokukhubazeka nokuhlolwa kwamandla kuzokwenziwa ngemva kokushisela;

④ Akuvunyelwe ukusunduza nokubeka izinto ezisindayo kuvalvu, futhi akuvunyelwe ukushaya insimbi eyinsimbi namavalvu angewona awensimbi ngesando sesandla.Ukufakwa kwama-valve anobubanzi obukhulu kufanele kube nabakaki.

2. Ukuvuza Ekupakisheni

Ukuvuza kwe-valve, Isizathu esikhulu ukuvuza kokupakisha.

Isizathu:

①Ukupakisha akukhethiwe kahle, akumelani nokugqwala kwendawo ephakathi, futhi akumelani nokusetshenziswa kwengcindezi ephezulu noma i-vacuum, izinga lokushisa eliphezulu noma izinga lokushisa eliphansi levalvu;

②Ukupakisha kufakwe ngokungalungile, futhi kukhona ukukhubazeka okufana nokushintshanisa okukhulu ngokuncane, ilunga eliboshwe ngezikulufu libi, futhi elingaphezulu liqinile futhi elingaphansi likhululekile;

③Iphakheji selikhulile futhi lilahlekelwe ukunwebeka kwalo ngoba lidlule impilo yalo yesevisi;

④Ukunemba kwesiqu se-valve akuphakeme, futhi kukhona ukukhubazeka njengokugoba, ukugqwala nokuguga;

⑤ Inombolo yemibuthano yokupakisha ayanele, futhi indlala ayicindezelwe ngokuqinile;

⑥ Indlala, amabhawodi, nezinye izingxenye zonakele, ukuze indlala ingakwazi ukucindezelwa;

⑦ Ukusebenza okungalungile, amandla amaningi, njll.;

⑧ I-gland ihlanekezelwe, futhi igebe phakathi kwendlala nesiqu lincane kakhulu noma likhulu kakhulu, okuholela ekuguga kwesiqu kanye nokulimala kokupakishwa.

Indlela yokunakekela:

① Izinto kanye nohlobo lokupakisha kufanele kukhethwe ngokuya ngezimo zokusebenza;

②Ukupakisha kufanele kufakwe ngendlela efanele ngokwemithethonqubo efanele, ukupakisha kufanele kubekwe futhi kucindezelwe ngakunye, futhi ukuhlangana kufanele kube ku-30℃ noma ku-45℃;

③ Ukupakisha osekusetshenziswe isikhathi eside kakhulu, okugugile nokonakele kufanele kushintshwe ngesikhathi;

④Isiqu kufanele siqondiswe futhi silungiswe ngemva kokugotshwa nokuguga, futhi lezo ezinomonakalo omkhulu kufanele zishintshwe ngesikhathi;

⑤ Ukupakisha kufanele kufakwe ngokwenani elishiwo lokuphenduka, indlala kufanele iqiniswe ngokulinganayo futhi ngokulinganayo, futhi umkhono wengcindezi kufanele ube nokuvunyelwa kwangaphambili kokuqina okungaphezu kuka-5mm;

⑥ Izindlala ezilimele, amabhawodi nezinye izakhi kufanele zilungiswe noma zishintshwe ngesikhathi;

⑦ Izinqubo zokusebenza kufanele zilandelwe, ngaphandle kwesondo lesandla esinomthelela, lisebenza ngesivinini esingaguquki namandla avamile;

⑧ Amabhawodi endlala kufanele aqiniswe ngokulinganayo futhi alingane.Uma igebe phakathi kwendlala nesiqu lincane kakhulu, igebe kufanele lenyuke ngokufanelekile;uma igebe phakathi kwendlala nesiqu likhulu kakhulu, kufanele lishintshwe.

3. Ukuvuza kwendawo yokuvala

Isizathu:

①Indawo yokuvala iphansi ngokungalingani futhi ayikwazi ukwenza umugqa oqinile;

②Isikhungo esiphezulu sokuxhuma phakathi kwesiqu se-valve nengxenye yokuvala imisiwe, ayilungile noma igugile;

③Isiqu se-valve sigobile noma asihlanganiswanga kahle, okubangela ukuthi ingxenye evalayo itsheke noma iphume ekuqondaneni;

④ Ikhwalithi yendawo yokuvala uphawu ayikhethiwe ngokungafanele noma i-valve ayikhethiwe ngokuvumelana nezimo zokusebenza.

Indlela yokunakekela:

①Ngokwezimo zokusebenza, impahla kanye nohlobo lwe-gasket kukhethwe kahle;

②Ukulungiswa okucophelelayo, ukusebenza kahle;

③ Amabhawodi kufanele aqiniswe ngokulinganayo futhi alingane.Uma kunesidingo, i-torque wrench kufanele isetshenziswe.Amandla okuqinisa ngaphambilini kufanele ahlangabezane nezidingo futhi akufanele abe mkhulu kakhulu noma abe mancane.Kufanele kube khona imvume ethile yokuqinisa ngaphambili phakathi kwe-flange noxhumo olunentambo;

④Inhlangano ye-gasket kufanele iqondaniswe phakathi nendawo, futhi amandla kufanele afane.I-gasket ayivunyelwe ukunqwabelana futhi isebenzise ama-gaskets aphindwe kabili;

⑤ Uma indawo yokubeka uphawu emile igqwalile, ilimele, futhi ikhwalithi yokucubungula ingekho phezulu, kufanele ilungiswe, igaywe, futhi ihlolwe ukuze ifakwe umbala, ukuze indawo yokuvala emile ihlangabezane nezidingo ezifanele;

⑥ Naka ukuhlanza lapho ufaka i-gasket, indawo yokuvala kufanele ihlanzwe ngophalafini, futhi i-gasket akufanele iwele phansi.

4. Ukuvuza ekuhlanganyeleni kwendandatho yokuvala

Isizathu:

①Indandatho yokuvala ayigoqwe ngokuqinile;

②Indandatho yokuvala ihlanganiswe nomzimba, futhi ikhwalithi yokuvela iphansi;

③Intambo yokuxhuma, isikulufu nendandatho yokucindezela yendandatho yokuvala ikhululekile;

④Uxhumano lwendandatho yokuvala lugqwalile.

Indlela yokunakekela:

①Ukuvuza endaweni yokuvala nendawo yokuginqika kufanele kujovwe ngento enamathelayo bese kulungiswa ngokurongeka;

②Indandatho yokuvala kufanele ishiselwe kabusha ngokuya ngemininingwane yokushisela.Uma i-weld engaphezulu ingakwazi ukulungiswa, i-welding yasekuqaleni kanye nokucubungula kuyosuswa;

③Khipha isikulufu bese ucindezela indandatho, hlanza, buyisela izingxenye ezilimele, gaya indawo yokuvala phakathi kophawu nesihlalo sokuxhuma, bese uhlanganisa kabusha.Ezingxenyeni ezinomonakalo omkhulu wokugqwala, zingalungiswa ngokushisela, ukubopha nezinye izindlela;

④Indawo yokuxhuma yeringi yokuvala igqwalile futhi ingalungiswa ngokugaya, ukuhlanganisa nezinye izindlela.Uma ingakwazi ukulungiswa, iringi yokuvala kufanele ishintshwe.

5. Ingxenye yokuvala iyawa futhi ivuze

Isizathu:

①Ukusebenza kumbi, ukuze ingxenye evalayo ibambeke noma idlule isikhungo esifile esiphezulu, futhi uxhumo lonakele futhi luphukile;

②Ukuxhuma kwengxenye yokuvala akuqinile, futhi kuyaxega futhi kuyawa;

③ Impahla yesixhumi ayilungile, futhi ayikwazi ukumelana nokugqwala kwe-medium kanye nokugqokwa komshini.

Indlela yokunakekela:

① Ukusebenza okulungile, vala i-valve ayikwazi ukusebenzisa amandla amaningi, vula i-valve ayikwazi ukudlula isikhungo esiphezulu esifile, ngemva kokuba i-valve ivuliwe ngokugcwele, isondo lesandla kufanele lihlehliswe kancane;

②Ukuxhumana phakathi kwengxenye evalayo nesiqu se-valve kufanele kuqine, futhi kufanele kube ne-backstop ekuxhumekeni kwentambo;

③ Izinsimbi ezisetshenziswa ukuxhuma ingxenye yokuvala kanye nesiqu se-valve kufanele zimelane nokugqwala kwendawo emaphakathi futhi zibe namandla athile okusebenza kanye nokumelana nokuguga.
