Kutshanje, ibhetshi yeiivalvu zesango lemela yepneumaticzomzi-mveliso wethu sele ziqalile ukupakishwa kwaye zilungele ukuthunyelwa. I-valve yesango ye-knife ye-pneumatic luhlobo lwevalve esetyenziswa ngokubanzi kwiindawo zoshishino, eziqhuba i-valve ukuba ivule kwaye ivale ngomoya ocinezelweyo, kwaye ineempawu zesakhiwo esilula, ukusebenza okulula kunye nokuphendula ngokukhawuleza.

Amalungu angundoqo evalve yesango eneflange abandakanya umzimba wevalve, isihlalo, isiqu sevalve, iringi yokutywina kunye ne-actuator. Xa umqondiso wenkqubo yokulawula, umoya ocinezelweyo ungena kwi-actuator kwaye utyhale i-stem up and down, ngaloo ndlela wenze imeko evulekileyo okanye evaliweyo phakathi kwediski kunye nesihlalo. Olu luyilo lwenza ukuba ivalve yesango yemela ye-pneumatic ilawule ukuhamba kolwelo ngokukhawuleza nangokuchanekileyo.

Izinto eziluncedo zevalve yesango yomoya:

1.Impendulo eKhawulezayo

Ngenxa yokusetyenziswa kwe-pneumatic drive, i-valve yesango ye-knife ye-pneumatic inokuvulwa ngokukhawuleza kwaye ivalwe ukuphucula ukusebenza kakuhle kwemveliso.

2.Ikhuselekile kwaye inokuthenjwa

Iivalvu zesango le-knife ye-pneumatic zivame ukuxhotyiswa ngezixhobo zokukhusela ukhuseleko, ezifana nokukhusela ukulayisha ngaphezulu, ubungqina bokuqhuma, njl., Ukuqinisekisa ukusebenza okukhuselekileyo phantsi kweemeko ezahlukeneyo zokusebenza.

3.Ukugcinwa okulula

Isakhiwo sevalvu yesango yemela ye-pneumatic ilula, kulula ukuyigcina yonke imihla kunye nokusombulula ingxaki.

4.Uluhlu olubanzi lwesicelo

Ingasetyenziselwa ubushushu obuphezulu, uxinzelelo oluphezulu, ukuthutha okuphakathi kwe-corrosive, ukulungelelanisa kwiimeko ezahlukeneyo ezinzima.

5.Ukugcinwa kwamandla kunye nokukhuselwa kwendalo

Xa kuthelekiswa nevalve yesango yotywino yombane, iivalvu zesango zemela ye-pneumatic zinokugcina amandla ngokufanelekileyo kwezinye iimeko zosetyenziso.

Ivalve yesango yentsimbi idlala indima ebalulekileyo kwimichiza, i-petroleum, unyango lwamanzi kunye namanye amashishini ngenxa yeenzuzo zayo ezizodwa. Iimveliso zevalve ye-Jinbin ngolawulo olungqongqo lomgangatho, ukuqinisekisa ukuba ivelufa yesango yemela yomzi-mveliso ngamnye inokuhlangabezana nemigangatho ephezulu yabathengi. Ukuba unayo nayiphi na imibuzo, nceda uqhagamshelane nathi ngezantsi.
