Ivalve yebhabhathane
0102030405
Uhlobo lweLever yeButterfly yeCPVC
Iimpawu zeMveliso
I-1, uyilo lwesakhiwo se-eccentric ephindwe kabini, ubomi benkonzo buphindwe ka-5 kwevalve yebhabhathane eqhelekileyo
I-2, i-torque encinci yokutshintsha.
Amalungu anokutshintshwa ahlangene kwaye anoqoqosho
Izinto eziphathekayo zi-nano-modified ukuphucula uxinzelelo
ukuxhathisa kunye nokuchasana kwempembelelo yemveliso
I-5, Umzimba wevalvu oqinileyo wokumelana noxinzelelo oluphezulu
I-6, i-100% yovavanyo loxinzelelo ngaphambi kokunikezelwa
I-7, Amalungu omzimba kunye nokutywinwa aphathwa ngokukodwa ukwenza ngcono ukusebenza kakuhle.
I-valve ye-butterfly eccentric yivalve yokulawula eqhelekileyo, ebonakaliswe yi-valve ye-flap yoyilo lwesakhiwo se-eccentric, kwinkqubo yokuvula kunye nokuvala ingenza ivalve yokutywinwa ibe ngcono ngoncedo lwe-eccentric design. Ivalve yebhabhathane jikelele neseziko ibhekisa kulwakhiwo lweflaphu yevalve ye-symmetric axis.
Xa kuthelekiswa neevalvu zebhabhathane jikelele, iivalve zebhabhathane eccentric ziphawulwa ngolwakhiwo oluntsonkothileyo kunye neendleko eziphezulu zokwenziwa. Nangona kunjalo, kwizicelo ezisebenzayo, ikwanayo nolawulo oluphezulu kunye nokusebenza kokutywinwa, ngakumbi kuxinzelelo oluphezulu, ubushushu obuphezulu, i-viscosity ephezulu kunye neminye imithombo yeendaba entsonkothileyo, ukusebenza kwevalve yebhabhathane eccentric kugqame ngakumbi, ukufezekisa ulawulo oluchanekileyo kunye noxinzelelo. ummiselo.
Yintoni inzuzo yevalve yebhabhathane eccentric?
1.ukuchasana nokuqukuqela okuncinci:
ngenxa yokuba i-valve ye-eccentric butterfly valve yenzelwe ukuba yahluke kwi-centrifugally ukusuka kwisihlalo ngomgama othile, xa i-medium ihamba ngevalve, indlela yokuhamba imfutshane ngakumbi kunezinye iivalve, ngaloo ndlela yenza ukuxhathisa okuncinci;
2.Ukutywinwa okuthembekileyo:
Ngexesha lenkqubo yokuvala i-valve ye-butterfly eccentric, uxinzelelo olukhulu luya kwenziwa phakathi kwe-spool kunye nesihlalo, esinokuqonda ukutywinwa okungcono; ngelixa ivula, ixhomekeke ikakhulu kwingxabano phakathi kwe-spool kunye nesihlalo sokuqinisekisa ukutywinwa.
3.Ilahleko yoxinzelelo oluncinci:
I-valve ye-butterfly eccentric ene-eccentric structure inokulungelelanisa umzila wokuhamba ophakathi ukuya kubuncinci, ngaloo ndlela inciphisa ukuxhathisa kunye nokulahlekelwa koxinzelelo.
