3. Ukuvuza kwendawo yokuvala uphawu

Isizathu:

(1) Ukubekwa uphawu kokugaya kungalingani, akukwazi ukwakha umugqa oseduze;

(2) Isikhungo esiphezulu sokuxhuma phakathi kwesiqu se-valve nengxenye yokuvala simisiwe, noma sigugile;

(3) Isiqu se-valve sigobile noma sihlanganiswe ngendlela engafanele, ukuze izingxenye ezivalayo zitsheke noma zingahambi endaweni;

(4) Ukukhetha okungalungile kwekhwalithi yempahla yokuvala uphawu noma ukukhethwa kwamavalvu ngokuya ngezimo zokusebenza.

Indlela yokunakekela:

(1) Khetha impahla kanye nohlobo lwe-gasket ngendlela efanele ngokwezimo zokusebenza;

(2) Ukulungiswa ngokucophelela, ukusebenza kahle;

(3) Ibhawodi kufanele iboshwe ngendlela efanayo futhi ilingane, futhi isikrufu setorque kufanele sisetshenziswe uma kunesidingo.Amandla okuqinisa ngaphambilini kufanele ahlangabezane nezidingo futhi akufanele abe mkhulu kakhulu noma abe mancane.Ukuxhumeka kwe-Flange nentambo kufanele kube negebe elithile lokuqinisa ngaphambili;

(4) Ukuhlanganiswa kwe-gasket kufanele kuhlangabezane namandla alungile, afanayo, i-gasket ayivunyelwe ukugoqa futhi isebenzise i-gasket ephindwe kabili;

(5) I-static seal surface corrosion, ukucutshungulwa komonakalo, ikhwalithi yokucubungula ayiphezulu, kufanele ilungiswe, ukugaya, ukuhlolwa kombala, ukuze indawo yokubeka uphawu emile ihlangabezane nezidingo ezifanele;

(6) Ukufakwa kwe-gasket kufanele kunake indawo ehlanzekile, evala uphawu kufanele ibe yi-parafini ecacile, i-gasket akufanele iwe.

4. Ukuvuza ekuxhumekeni kwendandatho yokuvala

Isizathu:

(1) Indandatho yokuvala ayigoqwe ngokuqinile

(2) Indandatho yokuvala nokushisela umzimba, ikhwalithi yokushisela engaphezulu ayilungile;

(3) Intambo yokuxhuma indandatho yokuvala, isikulufu, indandatho yokucindezela iyaxega;

(4) Indandatho yokuvala ixhunyiwe futhi igqwalile.

Indlela yokunakekela:

(1) Ukuvuza ekugoqeni kokuvalwa kufanele kugcwaliswe ngengcina bese kusongwa futhi kulungiswe;

(2) Indandatho yokuvala uphawu kufanele ilungiswe ngokuhambisana nemibandela yokushisela.Uma indawo engaphezulu ingakwazi ukulungiswa, indawo yokuqala kanye nokucubungula kufanele kususwe;

(3) Khipha isikulufu, hlanza indandatho yokucindezela, shintsha izingxenye ezilimele, ugaye indawo yokuvala nokuxhuma isihlalo esiseduze, bese uhlanganisa kabusha.Izingxenye ezonakaliswe ukugqwala zingalungiswa nge-welding, i-bonding, njll.

(4) Indawo yokuxhuma indandatho yokuvala igqwalile, engalungiswa ngokugaya, ukuhlanganisa, njll., futhi indandatho yokuvala kufanele ishintshwe lapho ingenakulungiseka.

5.Ukuvuza komzimba we-valve kanye nesembozo se-valve:

Isizathu:

(1)Ikhwalithi yokuphonswa kwensimbi eyinsimbi ayiphezulu, umzimba wamavalvu kanye nesembozo se-valve inezimbobo zesihlabathi, ukuhlelwa okuxekethile, ukufakwa kwe-slag nokunye ukukhubazeka;

(2) Umfantu obanda;

(3) I-welding engalungile, kukhona ukufakwa kwe-slag, okungeyona i-welding, imifantu yokucindezeleka nezinye iziphambeko;

(4)I-valve yensimbi eyinsimbi yonakele ngemva kokushaywa izinto ezinzima.

Indlela yokunakekela:

(1) Thuthukisa ikhwalithi yokuphonsa, futhi wenze ukuhlolwa kwamandla ngokuqinile ngokwemithethonqubo ngaphambi kokufakwa;

(2) Kumavalvu anamazinga okushisa angaphansi kuka-0° no-0°, ukugcinwa kokushisa noma ukuxutshwa kufanele kwenziwe, futhi amanzi kufanele akhishwe kumavalvu amisiwe ukusetshenziswa;

(3) I-weld yomzimba we-valve kanye nesembozo se-valve esakhiwe ngokushisela kufanele kwenziwe ngokulandela izinqubo zokusebenza zokushisela ezifanele, futhi ukutholakala kokukhubazeka nokuhlolwa kwamandla kufanele kwenziwe ngemva kokushisela;

(4) Akuvunyelwe ukusunduza izinto ezisindayo kuvalvu, futhi akuvunyelwe ukuthinta insimbi eyinsimbi namavalvu angewona awensimbi ngesando sesandla.

Siyakwamukela kuI-Jinbinvalve– umkhiqizi wamavalvu wekhwalithi ephezulu, ungazizwa ukhululekile ukusithinta uma udinga!Sizokwenza ngendlela oyifisayo isixazululo esingcono kakhulu kuwe!
