Zithini izinto ezakhiwe?

Kwiinkqubo zemizi mveliso,I-valves yesangoLuhlobo lwe-valve esetyenziswa rhoqo, ikakhulu isetyenziselwa ukufezekisa ulawulo olupheleleyo oluvulekileyo okanye olugqibeleleyo lwendawo ephakathi kwipayipi. Xa kuthelekiswa nezinye iintlobo zeValve, i-chibe zesango zinenjongo yokuthinta njengokuchaswa kokuhamba kweenyawo, ukusebenza kakuhle, kunye nobomi benkonzo ende. Abayili bobunjineli kunye nabaphathi bokuthenga, ukuqonda izinto eziphambili zesakhiwo se-valve yesango kuya kunceda ekukhetheni nasemva kokuvavanywa kwemveliso ngokuchanekileyo.

Apha ngezantsi, siya kuhlalutya izinto eziphambili ze-valve yesango esemgangathweni.

I-1. I-Valve Mub

I-veli ibhulukhwe yesona sakhiwo siphambili se-valve yesango, esetyenziselwa ukumelana noxinzelelo oluphakathi kwaye iqhagamshele i-upstream kunye nemibhobho ye-Dowwream. Ngokweemeko ezahlukeneyo zokusebenza, izixhobo eziqhelekileyo zomzimba wevali zibandakanya i-iron, intsimbi ephosakeleyo, intsimbi engenasimo, iqhekeza engenasimo, i-Nt. njl.

2. I-Valve Cover

Isigqubuthelo se-valve sifakwe ngaphezulu kwebhulukhwe yevalve, ikakhulu sitywina nokukhusela ubume bangaphakathi. Ukwenzela ukuba kube lula ukuhlolwa kunye nesondlo, ikhava ye-valve ye-valves enkulu yesango, i-valves ebiyelweyo kwaye ixhotyiswe ngokutywina irhasi okanye amakhonkco entsimbi yokutywina.

3. Isango

Isango lelona candelo liphambili lokufezekisa isenzo sokutshintsha. Inciphisa okanye inxibelelanisa ulwelo ngokuhamba uye ezantsi. Zininzi iindlela zamasango, ezinje ngesango elinye, isango eliphindwe kabini, isango lomtshato, isango elifanayo, njl. Njl njl. Amasango omtshato ahlala esetyenziswa kwiindawo zoxinzelelo oluphezulu ukuze aphucule indlela yokutywina.

I-4. I-Valve stem

I-valve stem ixhuma isaphetha okanye isenzo semali ngesango, kwaye liyinxalenye ephambili yokuhambisa amandla okuvula kunye nokuvala. Ngokweendlela ezahlukeneyo zolwakhiwo, isiqu sevalu sahlulwe saba ziindidi ezimbini: Uhlobo lwesiqu stem kunye nohlobo olungasebenziyo. Umgangatho wokuvula kunye nokuvala we-sloun stem valve icacile xa ujonga, nto leyo efanelekileyo ukuqaphela nokulondolozwa; Ulwakhiwo lwe-STE olungelulo lwe-STEM lonke lulungele indawo yokufaka kunye nezithuba ezincinci.

Ibhokisi yokukhupha

Ibhokisi yokuthenga isetyenziselwa ukuthintela i-medium ekuphumeni kwe-valve stem. Ihlala izaliswe yigrafu, i-ptfe okanye ezinye izinto zokutywina, kwaye itywina lenziwa ngokucinezela i-gland. Ngaphantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu, ukhetho lokupakisha lunefuthe elikhulu kwintsebenzo yokutywina ngokubanzi, eyinxalenye ebalulekileyo yenkqubo yokuthenga engenakutyeshelwa.

I-6, isandla ngesandla okanye isixhobo sokuqhuba

Isandla sesandla yindlela eqhelekileyo yokuqhuba yee-valves zesango kwaye kulula ukusebenza. I-caliber enkulu okanye i-valve yesango eliphezulu, umbane, i-pneumatic okanye i-pneumatic okanye i-hydrausic of Drauators zihlala zixhotyiswe ukufezekisa ulawulo olude okanye imisebenzi yokulawula ngokuzenzekelayo. Ukukhetha imo yemodi yokuqhuba kufuneka kugqitywe ngokweemfuno zobunjineli.

I-7. Isibini sokutywina

I-Patrip yokutywina ibandakanya isango kunye nesihlalo sevali, esiyintloko yokuqinisekisa ukusebenza kwevali. Izibini zokusebenza eziphezulu zinokumelana rhoqo ngezenzo zezenzo zokuvula nokuvala, kwaye zigcine ukutywina kwezinto eziphathwayo ezifana neendawo ezinobunzima ezifana noxinzelelo oluphezulu kunye nokususwa. Iimveliso ezisemgangathweni eziphezulu zihlala zenziwa ze-carbide ye-carbide okanye i-alloy enganyangekiyo.

8. Ulwakhiwo lweSikhokelo

Ukuze kuqinisekiswe umsebenzi ozinzileyo wesango ngexesha lenkqubo yokuvula kunye nokuvala, ezinye gvalvesbaxhotyiswe nge-rooves okanye bakhokele izikhonkwane. Olu uyilo lolwakhiwo lunokuthintela ngokufanelekileyo isango ukuba liphelise okanye libambelele, kwaye lilungele ngokulinganayo indawo yokusebenza kunye namanqanaba aphezulu okuqala okanye amasuntswana aphezulu.

Ukuqonda ubume beI-Palve yesangoAyincedi nje ukukhetha imodeli elungileyo, kodwa iphucula ukusebenza ngempumelelo kunye nokunciphisa ireyithi yokuphela kolondolozo lwamva kunye ne-overthaul. Abathengi, ukuthenga akunakwenziwa ngokusekwe kwixabiso yedwa, kunye nezixhobo, ulwakhiwo, ukusebenza, ukusebenza kwentsebenzo kunye nomsebenzi kunye nezakhono zobugcisa kufuneka kuthathelwe ingqalelo ngokupheleleyo.

Inkampani yethu igxile kubume beVova yeHlabathi iminyaka emininzi, ibonelela ngeemveliso zexabiso le-sango leentlobo zolwakhiwo ezahlukeneyo, ezixhasa iinkonzo ezingekho mgangathweni kunye neenkonzo zobuchwephesha. Ukuba unayo nayiphi na imibuzo malunga nokhetho, nceda uzive ukhululekile ukubaQhagamshelana nathi.
