Iivalvu zebhabhathane zentsimbi ukusuka kwisinyithi zisetyenziswa kakhulu kwi-metallurgy, kumbane, kwi-petrochemical, kubonelelo lwamanzi nakwimibhobho yamanzi, kulwakhiwo lukamasipala nakwezinye iipayipi zoshishino apho ubushushu obuphakathi buyi-≤425°C ukulungisa ukuhamba kwamanzi kunye nolwelo olunqumlekileyo.Ngexesha leeholide zesizwe, iworkshop ye-NSEN igqibezela iqela leevalvu zebhabhathane zesinyithi ezivalayo ezisebenza kwicala ngalinye. Eli qela leevalvu zebhabhathane zombane linokwenza ulawulo olukude kunye nokusebenza kwamalahle.

● I-bracket yokudibanisa isebenzisa umgangatho we-ISO5211 kwaye inokudityaniswa nezixhobo ezahlukeneyo zombane, zomoya, ze-hydraulic, zesandla kunye nezinye izixhobo zokuqhuba

●Kukho umgama othile phakathi kwephezulu leflange ephezulu kunye ne-actuator esebenzayo, nto leyo enceda ekukhuseleni i-actuator kubushushu obugqithisileyo.

Umzobo wee-terminals zocingo lwe-ON OFF uhlobo lwe-butterfly valve yombane

Xa umbane ufika, indlela ohamba ngayo umbane ilungisiwe. Ukuze umbane ungaqhagamshelwa kwicala elingalunganga, umsebenzisi kufuneka avule ipleyiti yevalvu ngesandla ngama-30 degrees ngaphambi kokuba avule umbane okokuqala, aze ajonge indlela ipleyiti yesalathisi kunye nendlela evuleka ngayo ivalvu. Ingaba iyahambelana? Emva koko buyisela incwadi yemiyalelo kumbane, ulandele imiyalelo, umzobo wocingo, umzobo womgaqo wolawulo, kwaye uqinisekise umbane ochanekileyo, uze uvule/uvale ivalvu ngeqhosha elikwibhokisi yokulawula. Ukuba intambo yombane iqhagamshelwe ngasemva, iya kubangela ukuba iswitshi yokuhamba ingaphumeleli kwaye yonakalise izixhobo zombane kunye nezixhobo zombane.

Xa ivalvu yebhabhathane yombane isetyenziswa, ukuba ayisebenzi, yeka ukuyisebenzisa ngoko nangoko uze ufumane unobangela

Iimpawu zevalvu yebhabhathane eqinileyo yombane:

Uyilo lomgaqo we-triple eccentricity lwenza indlela yokuhamba kwesithuba yomphezulu wokutywina ibe yeyona ifanelekileyo. Akukho kungqubana nokuphazamiseka phakathi kwemiphezulu yokutywina. Ukongeza, izinto zokutywina zikhethwa ngokufanelekileyo, ukuze ivalvu yebhabhathane ibe nokusebenza kokutywina, ukumelana nokugqwala, ukumelana nobushushu obuphezulu kunye nokuxhathisa. Ukugoba kuqinisekisiwe ngokuthembekileyo. Iimpawu zayo eziphambili zezi zilandelayo:

1. I-torque encinci yokusebenza, ukusebenza okulula, ukonga abasebenzi kunye nobulumko;

2. Ulwakhiwo oluyi-eccentric olunemilinganiselo emithathu lwenza idiski yebhabhathane iqine kwaye iqine, kwaye ukusebenza kwayo kokutywina kuthembekile, kufikelela ekungavuzini nanye;

3. Ukumelana noxinzelelo oluphezulu, ukumelana nokugqwala, ukumelana nokuguguleka, ubomi obude benkonzo, njl.
