3. Ukuvuza kobuso bokuvala

Isizathu:

(1) Ukuvala ubuso obugayiwe ngokungalingani, akukwazi ukwakha umugqa oseduze;

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

(3) Isiqu sevalvu sigobile noma asihlanganiswanga kahle, ukuze izingxenye zokuvala zigobe noma zingabi endaweni yazo;

(4) Ukukhetha okungafanele kwekhwalithi yezinto zokuvala noma ukukhetha ivalvu ngokwezimo zokusebenza.

Indlela yokulungisa:

(1) Khetha izinto kanye nohlobo lwe-gasket ngendlela efanele ngokuya ngezimo zokusebenza;

(2) Ukulungiswa ngokucophelela, ukusebenza kahle;

(3) Ibhawodi kufanele lifakwe isikulufu esifanayo futhi esilinganayo, futhi i-torque wrench kufanele isetshenziswe uma kudingeka. Amandla okuqinisa ngaphambi kokusebenzisa kufanele ahlangabezane nezidingo futhi akufanele abe makhulu kakhulu noma abe mancane. Ukuxhumeka kwe-flange kanye nentambo kufanele kube nesikhala esithile sokuqinisa ngaphambi kokusebenzisa;

(4) Ukuhlanganiswa kwe-gasket kufanele kuhlangabezane namandla afanele, afanayo, i-gasket ayivunyelwe ukugoqa nokusebenzisa i-gasket ephindwe kabili;

(5) Ukugqwala kwendawo yokuvala engashukumi, ukucubungula umonakalo, ikhwalithi yokucubungula ayiphezulu, kufanele kulungiswe, kugaywe, kuhlolwe umbala, ukuze indawo yokuvala engashukumi ihlangabezane nezidingo ezifanele;

(6) Ukufakwa kwe-gasket kufanele kunake indawo ehlanzekile, evaliwe kufanele ibe ne-parafini ecacile, i-gasket akufanele iwe.

4. Ukuvuza ekuxhumekeni kwendandatho yokuvala

Isizathu:

(1) Indandatho yokuvala ayigoqiwe kahle

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

(3) Intambo yokuxhumanisa indandatho yokuvala, isikulufu, indandatho yokucindezela ikhululekile;

(4) Indandatho yokuvala ixhunyiwe futhi igqwalile.

Indlela yokulungisa:

(1) Ukuvuza lapho kugoqwa khona ukuvala kufanele kugcwaliswe nge-glue bese kugoqwa bese kulungiswa;

(2) Indandatho yokuvala kufanele ilungiswe ngokwencazelo yokushisela. Uma indawo yokubeka ingaphezulu ingenakulungiseka, indawo yokuqala kanye nokucubungula kufanele kususwe;

(3) Susa isikulufu, hlanza indandatho yokucindezela, shintsha izingxenye ezonakele, gaya indawo eseduze nesihlalo sokuvala nokuxhuma, bese uhlanganisa kabusha. Izingxenye ezonakele ngenxa yokugqwala zingalungiswa ngokushisela, ukubopha, njll.

(4) Ubuso bokuxhumanisa indandatho yokubopha bugqwalile, okungalungiswa ngokugaya, ukubopha, njll., futhi indandatho yokubopha kufanele ishintshwe uma ingenakulungiseka.

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

Isizathu:

(1) Ikhwalithi yokusatshalaliswa kwensimbi ephothiwe ayiphezulu, umzimba we-valve kanye nomzimba wesembozo se-valve unezimbobo zesihlabathi, ukuhleleka okuxekethile, ukufakwa kwe-slag kanye nezinye iziphambeko;

(2) Ukuqhekeka okuqandisayo;

(3) Ukushisela okubi, kukhona ukufakwa kwe-slag, ukungashiseli, imifantu yokucindezeleka kanye nezinye izinkinga;

(4) Ivalvu yensimbi ephonswe phansi yonakele ngemva kokushaywa izinto ezisindayo.

Indlela yokulungisa:

(1) Thuthukisa ikhwalithi yokukhipha, futhi wenze ukuhlolwa kwamandla ngokuqinile ngokwemigomo ngaphambi kokufakwa;

(2) Kuma-valve anamazinga okushisa angaphansi kuka-0° no-0°, kufanele kugcinwe ukushisa noma kuxutshwe, futhi amanzi kufanele akhishwe kuma-valve ayeke ukusetshenziswa;

(3) Ukushintshwa komzimba wevalvu kanye nesembozo sevalvu esakhiwe ngokushintshwa kufanele kwenziwe ngokwezinqubo zokusebenza zokushintshwa ezifanele, futhi ukuhlolwa kokutholwa kwamaphutha kanye namandla kufanele kwenziwe ngemva kokushintshwa;

(4) Akuvunyelwe ukusunduza izinto ezisindayo ku-valve, futhi akuvunyelwe ukushaya ama-valve ensimbi ephonswe kanye nalawo angewona awensimbi ngesando sesandla.

Siyakwamukela ku-I-Jinbinvalve– umenzi wamavalvu asezingeni eliphezulu, ungazizwa ukhululekile ukuxhumana nathi uma udinga! Sizokwenza ngezifiso ikhambi elifanele wena!
