I-NORTECHis enye yezona zihamba phambili zaseTshayinaIvalve yeglowubhu Umenzi kunye noMboneleli.

Ziziphi iingenelo kunye nokungalunganga kweivalve yeglowubhu?
Iindawo zokuvula kunye nokuvala i-valve yokuvala ziyi-petals ezibanzi ezimile okweplagi, kwaye indawo yokutywina i-flat okanye i-conical, kwaye ihamba ngokulandelelana kumgca ophakathi kwamanzi.Ifomu yentshukumo yentonga inohlobo lwentonga yokuphakamisa (isiqu sevalve siphakanyiswa kwaye sithotywe, ivili lesandla alinyuki), kwaye kukho uhlobo lwentonga ejikelezayo ephakamisayo (ivili lesandla kunye nesiqu sevalve sijikeleza kwaye siphakame kunye, kwaye Indongomane ibekwe kumzimba wevalvu).I-valve yokumisa ifanelekile kuphela ukuvula ngokupheleleyo kwaye ivalwe ngokupheleleyo, ukulungiswa kunye ne-throttling akuvumelekanga.
Ivalve yokumisa yivalve yokutywina ngokunyanzeliswa, ngoko xa ivalve ivaliwe, uxinzelelo kufuneka lufakwe kwiflap ukunyanzela umphezulu wokutywina ungavuzi.Xa i-medium ingena kwi-valve yesithandathu ukusuka ngaphantsi kwe-disc ye-valve, ukuchasana okufuneka ukuba amandla okusebenza anqobe yi-friction force ye-valve stem kunye nokupakisha kunye ne-thrust eyenziwa nguxinzelelo lwe-medium.Amandla okuvala ivalve makhulu kunamandla okuvula ivalve, ngoko ke ivalve Ububanzi bentonga kufuneka bube bukhulu, kungenjalo umbhobho we-valve stem jacking uya kusilela.Kwiminyaka yakutshanje, ukususela ekuveleni kweevalve zokuzitywina, indlela yokuhamba ephakathi yevalve yokuvala itshintshile ukusuka phezulu kwevalve ukuya kwindawo yevalve.Ngeli xesha, phantsi kwesenzo soxinzelelo oluphakathi, amandla okuvala i-valve encinci, ngelixa i-valve yokuvula i-valve inkulu.Ububanzi bunokuncitshiswa ngokufanelekileyo.Ngexesha elifanayo, phantsi kwesenzo se-medium, olu hlobo lwevalve luphinde lube lukhuni.Ivalve yelizwe lam i-“Sanhua” yakha yachaza ukuba indlela yokuhamba kwevalve yokumisa kufuneka isuke phezulu iye ezantsi.
Xa i-valve yokuvala ivuliwe, xa ukuphakama kokuvula i-disc ku-25% -30% ye-diameter ye-nominal, ukuhamba kuye kwafikelela kwinqanaba eliphezulu, ebonisa ukuba i-valve ifikelele kwindawo evulekile ngokupheleleyo.Ngoko ke, indawo evulekile ngokupheleleyo yevalve yokuvala kufuneka igqitywe ngokubethelwa kwediski ye-valve.
Ivalve yokumisa inokohlulwa ibe: ivelufa yokumisa, ivalve yokumisa intambo ephezulu, ivalve yokumisa intambo esezantsi, ivalve yokumisa ethe tye, ivalve yokumisa i-angle, ivalve yokumisa yeendlela ezintathu, ivelufa yokumisa yangoku, ivalve yokumisa iplanger, inaliti yokumisa ivalve yeglowubhu.
Izinto eziluncedo: isakhiwo esilula, ukuveliswa kunye nokugcinwa ngokufanelekileyo.
I-stroke esebenzayo incinci, kwaye ixesha lokuvula kunye nokuvala lifutshane.
Ukusebenza kakuhle kokutywina, ukungqubana okuncinci phakathi kweendawo zokutywina, kunye nobomi obude.
Izinto ezingeloncedo:
Ukumelana nolwelo kukhulu, kwaye amandla afunekayo ekuvuleni nasekuvaleni makhulu.
Ayifanelekanga kumajelo eendaba ngamasuntswana, i-viscosity ephezulu kwaye kulula ukuyicoca.
Ukusebenza kakubi kohlengahlengiso
Imigqaliselo yofakelo kunye nokugcinwa: Ivalve yokumisa esebenza livili lesandla kunye nomqheba unokufakelwa kuyo nayiphi na indawo yombhobho.
Amavili ezandla, izibambo kunye neendlela eziguquguqukayo azivumelekanga ukuba zisetyenziswe ekuphakamiseni.Umkhombandlela wokuqukuqela ophakathi kufuneka uhambelane necala lotolo oluboniswe kumzimba wevalvu.
