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 ngokushisela, ukubopha, 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 ayikho phezulu, 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 ezisebenzayo zokushisela, futhi ukutholwa okungalungile 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!
