Isinyithi sombane ukuya kwiivalvu zebhabhathane zetsimbi zisetyenziswa ngokubanzi kwisinyithi, amandla ombane, i-petrochemical, unikezelo lwamanzi kunye ne-drainage, ukwakhiwa kukamasipala kunye neminye imibhobho yoshishino apho ubushushu obuphakathi bungu-≤425 ° C ukulungisa ukuhamba kunye nokunqunyulwa kwamanzi.Ngexesha leeholide zesizwe, iworkshop ye-NSEN igqibezela ibhetshi yeevalvu zentsimbi ezitywina ibhabhathane ezivaliweyo zombane.Le bhetshi yeevalvu zebhabhathane zombane zinokuqonda ulawulo olukude kunye nokusebenza kwamalahle.

● Isibiyeli sokudibanisa sisebenzisa umgangatho we-ISO5211 kwaye sinokuqhagamshelwa kwizinto ezahlukeneyo zombane, ipneumatic, ihydraulic, manual kunye nezinye izixhobo zokuqhuba.

●Kukho umgama othile phakathi komphezulu weflange kunye ne-actuator esebenzayo, enceda ukukhusela i-actuator kubushushu obungaphezulu.

VALIWE chwetheza iitheminali zeetheminali zeentambo zebhabhathane zebhabhathane

Xa umbane uhanjiswa, i-stroke yendlela yokulawula ilungisiwe.Ukuze uthintele amandla ukuba adityaniswe kwicala elingalunganga, umsebenzisi kufuneka avule ngesandla i-valve plate 30 degrees ngaphambi kokuba avule amandla okokuqala, kwaye ukhangele isalathiso sepleyiti yesalathisi kunye nendlela yokuvula i-valve.Ngaba iyahambelana?Emva koko buyisela i-manual kumbane, landela imiyalelo, umzobo we-wiring, idayagram yomgaqo wokulawula, kwaye uqinisekise i-wiring echanekileyo, uze uvule / uvale i-valve ngeqhosha kwibhokisi yokulawula.Ukuba intambo yamandla iqhagamshelwe umva, iya kubangela ukuba utshintsho lokuhamba lungasebenzi kwaye lonakalise igiya leentshulube kunye nezixhobo zombane.

Xa i-valve yebhabhathane yombane isetyenziswa, ukuba iyasilela, yeka ukuyisebenzisa ngokukhawuleza kwaye ufumane isizathu

Iimpawu zevalve yebhabhathane eqinileyo yombane:

Uyilo lomgaqo-siseko we-eccentricity kathathu wenza umkhondo wentshukumo yendawo yokutywina ulungelelaniswe.Akukho kungqubuzana kunye nokuphazamiseka phakathi kweendawo zokutywina.Ukongezelela, izinto zokutywina zikhethwe ngokufanelekileyo, ukwenzela ukuba i-valve ye-butterfly ibe nomsebenzi wokutywina, ukuxhathisa ukubola, ukumelana nokushisa okuphezulu kunye nokuchasana.I-grindability iqinisekisiwe ngokuthembekileyo.Iimpawu zayo eziphambili zezi zilandelayo:

1. Itorque encinci yokusebenza, ukusebenza ngokulula, ukonga abasebenzi kunye nobulumko;

2. Ulwakhiwo lwe-eccentric olunemigangatho emithathu lwenza ukuba i-butterfly disc iqine kwaye iqine, kwaye ukusebenza kwayo kokutywinwa kuthembekile, ukuphumeza ukuvuza kwe-zero;

3. Ukuxhatshazwa koxinzelelo oluphezulu, ukuxhathisa ukubola, ukuxhatshazwa kokugqoka, ubomi obude benkonzo, njl.
