Kwinkqubo yokusebenzisa iivalve, unokuhlangabezana nomonakalo wetywina, ngaba uyazi ukuba yintoni isizathu? Nantsi into oza kuthetha ngayo.Itywina lidlala indima ekusikeni nasekudibaniseni, ukulungelelanisa nokusabalalisa, ukwahlula kunye nokuxuba imidiya kwijelo levalve, ngoko ke indawo yokutywina isoloko iphantsi kokuhlwa, ukukhukuliseka, ukuguga kunye nokonakaliswa lula yi-medium.

Izizathu zomonakalo wokutywinwa komphezulu ngumonakalo owenziwe ngumntu kunye nomonakalo wendalo. Umonakalo owenziwe ngumntu ubangelwa zizinto ezifana noyilo olungekho mgangathweni, ukwenziwa kakubi kwezinto, ukukhetha izinto ngendlela engafanelekanga nokufakwa ngendlela engafanelekanga. Umonakalo wendalo kukunxitywa kwevalve phantsi kweemeko eziqhelekileyo zokusebenza, kwaye ngumonakalo obangelwa kukuhlwa okungenakuphepheka kunye nokukhukuliseka okuphakathi kwindawo yokutywina.

Izizathu zomonakalo wendalo zinokushwankathelwa ngolu hlobo lulandelayo:

1. Ukutywinwa umgangatho wokucubungula umphezulu awulungile

Ukuba kukho iziphene ezifana nokuqhekeka, i-pores kunye ne-ballast kwindawo yokutywinwa, kubangelwa ukukhetha okungafanelekanga kwemigangatho yokushisa kunye nokuphathwa kokushisa kunye nokusebenza kakubi kwinkqubo yokucoca kunye nokushisa. IlukhuniI-ess yendawo yokutywinwa iphezulu kakhulu okanye iphantsi kakhulu, ebangelwa kukukhethwa kwezinto ezingalunganga okanye unyango olungafanelekanga lobushushu. Ubunzima obungalinganiyo kunye nokumelana nokungagqwali kwendawo yokutywina kubangelwa ikakhulu kukuvuthela isinyithi esisezantsi ukuya phezulu ngexesha lenkqubo ye-welding ye-surfacing kunye nokudibanisa ukubunjwa kwe-alloy yendawo yokutywinwa. Kakade ke, kusenokubakho imiba yoyilo.

2. Umonakalo obangelwa kukukhetha okungafanelekanga kunye nokusebenza kakubi

Ukusebenza okuphambili kukuba i-valve ayikhethwanga ngokweemeko zokusebenza, kwaye i-valve yokuqhawula isetyenziswe njenge-valve ye-throttle, okubangelwa uxinzelelo olukhulu kakhulu lokuvala kunye nokuvalwa ngokukhawuleza okanye ukuvala i-lax, ukwenzela ukuba indawo yokutywina ikhutshwe. kwaye igugile.Ufakelo olungafanelekanga kunye nokugcinwa okungahambi kakuhle kwakhokelela ekusebenzeni okungaqhelekanga kwendawo yokutywina, kunye nevalve esebenza ngesifo, eyonakalisa ngaphambi kwexesha indawo yokutywina.

3. Ukonakala kweekhemikhali phakathi

Xa isiphakathi esijikeleze umphezulu wokutywina singavelisi umsinga, i-mI-edium isebenza ngokuthe ngqo kumphezulu wokutywina ngokwekhemikhali kwaye idle umphezulu wokutywina. Ukonakala kwe-Electrochemical, ukutywina ukudibana komphezulu kunye nomnye, ukutywina ukudibana komphezulu kunye nomzimba ovalayo kunye nomzimba wevalvu, kunye nomahluko wokuxinana ophakathi, umahluko woxinzelelo lweoksijini kunye ezinye izizathu, ziya kuvelisa umahluko onokubakho, ukubola kwe-electrochemical, okubangela ukuba icala le-anode lomphezulu wokutywina lidliwe.

4. Ukhukuliseko oluphakathi

Kuyisiphumo sokugqoka, ukuguguleka kunye ne-cavitation yendawo yokutywina xa i-medium ihamba. Ngesantya esithile, amasuntswana amahle adadayo aphakathi anempembelelo kumphezulu wokutywina, ebangela umonakalo wendawo; isantya esiphezulu esindiqukuqelayoi-dium ihlamba ngokuthe ngqo indawo yokutywina, eyenza umonakalo wendawo; xa i-medium mix flow flow and vaporization yendawo, amaqamza agqabhuka kwaye achaphazela indawo yokutywina, ebangela umonakalo wendawo. Ukhukuliseko oluphakathi ludityaniswe nesenzo esitshintshayo somhlwa kweekhemikhali kuya kuqinisa ngamandla umphezulu wokutywina.

5. Umonakalo womatshini

Umphezulu wokutywina uya konakaliswa kwinkqubo yokuvula nokuvala, njenges ukugruzuka, ukungqubeka, ukukhama njalo njalo. Phakathi kweendawo ezimbini zokutywinwa, ii-athomu zingena komnye nomnye phantsi kwesenzo sokushisa okuphezulu kunye noxinzelelo oluphezulu, okubangelwa ukunamathela. Xa iindawo ezimbini zokutywina zihamba komnye nomnye, ukunamathela kulula ukuzoba. Okukhona uphezulu uburhabaxa bomphezulu bomphezulu wokutywina, kokukhona kwenzeka lula le nto. Ngethuba lenkqubo yokuvala i-valve kunye ne-disc ye-valve kwinkqubo yokubuyela kwisihlalo, indawo yokutywina iya kwenzakala kwaye icinezelwe, ibangele ukunxiba kwendawo okanye ukunyanzeliswa kwindawo yokutywina.

6. Umonakalo wokudinwa

Kwixesha elide lokusetyenziswa kwendawo yokutywina, phantsi kwesenzo somthwalo otshintshanayo, indawo yokutywina iya kuvelisa ukukhathala, ukuqhekeka kunye noluhlu lokuqhawula. Irabha kunye neplastiki emva kokusetyenziswa kwexesha elide, kulula ukuvelisa into yokuguga, okubangela ukusebenza kakubi.

Ukususela kuhlalutyo olungentla lwezizathu zomonakalo wokutywinwa kwendawo yokutywina, kunokubonwa ukuba ukwenzela ukuba kuphuculwe umgangatho kunye nobomi benkonzo ye-valve yokutywinwa kwendawo, izinto ezifanelekileyo zokutywinwa kwendawo, isakhiwo sokutywinwa esifanelekileyo kunye neendlela zokucubungula kufuneka zikhethwe.
