Uhlobo lwevalvu yesityalo sekhemikhali kunye nendawo yokusetyenziswa (kunye nohlobo olusebenzayo)

Emva kokuveliswa kweenjini zomphunga, kwiminyaka engamashumi amabini okanye engamashumi amathathu edlulileyo, ngenxa yemfuneko ye-oyile ekrwada, izityalo zemichiza, amaziko ombane, ishishini lesinyithi, iinqanawa, ukuveliswa kwamandla enyukliya, i-aerospace kunye neminye imimandla, izibonelelo ezingcono zibekwe phambili ngokucacileyo. iivalvu, kunye neevalvu zemveliso yoshishino nazo ezahlukeneyo kwiintlobo.Njengevalveukwazisa indawo yokufakwa kwevalvu yohlobo lweekhemikhali kunye nokusebenza ngokufanelekileyo.

Uhlobo lwevalvu yesityalo sekhemikhali kunye nokusetyenziswa

1. Yahlula ngokwezintlu ngokokusebenza kunye nenkundla yesicelo

(1) ivelufa yokuqhawula: isivalo esisikiweyo saziwa ngokuba yintambo yedijithali ivelufa yeTV, kwaye isiphumo saso kukufikelela okanye ukuqhawula unxibelelwano oluphakathi kumbhobho. Iivalvu ezisikiweyo ziquka iivalve zeglowubhu, iivalve zeglowubhu, iiplagi zeplagi, iivalve, iidisk valves kunye nediaphragm.

(2) ivelufa yokukhangela: ivelufa yokukhangela ikwabizwa ngokuba yivalve ye-throttle okanye ivelufa yokukhangela, isiphumo sayo kukuthintela okuphakathi kumbhobho onyuka ngomlambo. Impompo ye-Centrifugal i-hygroscopic esuka kwivalve esezantsi yempompo ikwayeyodidi lwevalvu yokutshekisha.

(3) ivelufa: umsebenzi wodidi lwevalve yokhuseleko kukuphepha uxinzelelo olusebenzayo lwesixhobo sombhobho okanye isixhobo siphezulu kunexabiso elichaziweyo, ukuze kufezekiswe injongo yokhuseleko lokhuseleko.

(4) ivelufa yokulawula: iklasi yevalve elawulayo ibandakanya ivalve elawulayo, ivalve yendlela enye kunye nevalve yokulawula uxinzelelo, isiphumo sayo kukulungelelanisa uxinzelelo olusebenzayo lwendlela ephakathi, ukuhamba ngokupheleleyo kunye nezinye ezintathu.

(5) ivelufa yokwahlula: udidi lwevalve ye-shunt lubandakanya iintlobo ngeentlobo zeevalvu zeendlela ezininzi kunye nezirhintyi zomphunga, njl. njl., isiphumo salo kukuhambisa, ukwahlula ngaphandle okanye ukuxuba isiphakathi kumbhobho.

2. Ukuhlelwa ngokweklasi yephawundi

(1) Ivalve yokufunxa: ibhekisa kwivalve enoxinzelelo olungaphantsi koxinzelelo oluqhelekileyo lomoya.

(2) Ivalve yombane ophantsi: ibhekisa kudidi lwephawundi PN ¡Ü 1.6mpa ivelufa.

(3) ivalve yoxinzelelo oluphakathi: ibhekisa kwi-PN yoxinzelelo lwegama yi-2.5, 4.0, 6.4Mpa valve.

(4) Ivalve yoxinzelelo oluphezulu: ibhekisa kwivalve enoxinzelelo olusebenzayo lwe-PN ye-10 ~ 80Mpa.

(5) ivalve yoxinzelelo oluphezulu: ibhekisa kwivalve ye-PN¡Ý100Mpa.

3. Hlela ngokweqondo lokushisa lokusebenza

(1) low temperature valve: for medium operating temperature t (1) ivalve yobushushu obuphantsi: kubushushu obuphakathi bokusebenza t

(2) ivalve yobushushu obuphantsi: ubushushu obuphakathi bokusebenza -100¡æ¡Ü T ¡Ü-40¡æ valve.

(3) Ivalve yobushushu obuqhelekileyo: ubushushu obuphakathi bokusebenza -40¡æ¡Ü T ¡Ü120¡æ valve.

(4) Ivalve yobushushu obuphakathi: kubushushu obuphakathi bokusebenza kwe120¡æ

(5) ivalve yobushushu obuphezulu: kubushushu obuphakathi bokusebenza T >450¡æ valve.

4. Hlela ngokwefom yokupasa kwabafundi

(1) Ivalve ezenzekelayo ayingomandla angaphandle okukhuthaza, kodwa ngamandla omthombo ngokwawo ukwenza indawo yevalve yesivalo. Njengevalve, ivalve yokulawula uxinzelelo, i-steam trap, ivalve yokukhangela, ivalve yokulawula ngokuzenzekelayo njalo njalo.

(2) Ivalve yokulawula amandla okuqhuba: ivalve yokulawula amandla okuqhuba ingasebenzisa izixhobo ezahlukeneyo zamandla ukukhuthaza.

Ivalve yolawulo lombane: ukuthembela kubunjineli bamandla ukukhuthaza ivalve.

Ivalve yepneumatic: ivalve eqhutywa luxinzelelo lomoya.

Ivalve yeHydraulic: ivalve eqhutywa luxinzelelo lolwelo olufana neoyile.

Ukongezelela, kukho kwakhona amacandelo amacandelo angasentla eendlela zokuqhuba, ezifana ne-gas-electric regulating valves.

(3) Ivalve ye-Manual: ivalve ye-manual ixhomekeke kwi-spindle, i-rocker, i-rod bar, i-sprocket chain, ngezibonelelo zabantu ukulawula ukuma kwevalve. Xa ivalve yokuvula kunye netorque yokuvala inkulu ngokwentelekiso, ivili okanye isinciphisi segiya yeentshulube sinokusetwa phakathi kwe-spindle kunye nesihlalo. Ukuba kuyimfuneko, i-cardan joints kunye ne-shafts ejikelezayo ingasetyenziselwa ukusetyenziswa kwexesha elide.

5, ngokokwahlulwa kwedayamitha yedayamitha

(1) Ivalve yedayamitha encinci: Ivalve yedayamitha encinci DN¡Ü40mm ivelufa.

(2) Ivalve yedayamitha ephakathi: i-DN yedayamitha eyi-50 ~ 300mm ivelufa.

(3) Ivalve yedayamitha enkulu: ivalve yedayamitha ye-DN ye-350 ~ 1200mm ivelufa.

(4) Ivalve enkulu: ivalve enedayamitha encinane DN¡Ý1400mm.

6. Cazulula ngokohlobo lwesakhiwo

(1) imilo yevalvu: iindawo zokuvula kunye nokuvala (ivalve yepiston) ziqhutywa sisitulo ecaleni kwe-axis yevalve yesango loxinzelelo oluphezulu ukulungelelanisa intshukumo yokufaneleka;

(2) imilo yevalve yeplagi: iindawo zokuvula kunye nokuvala (ivalve yeglowubhu) zityhalwa sisitulo sevalve ecaleni kwe-axis yevalve yesango elithe nkqo ukuze kulungiswe intshukumo yokomelela;

(3) ivelufa yokuvala: iindawo zokuvula nokuvala (iplagi yekhowuni okanye ibhola) ngokuqinileyo kujikelezo lweaxis yayo;

(6) Umgca wempompo yepleyiti ejikelezayo: iindawo zokuvula kunye nokuvala ziqengqeleka kwicala lomjelo wokhuseleko othe nkqo.

7. Yahlula ngokwendlela yoqhagamshelo

(1) Ivalve yoqhagamshelo oluphothiweyo: umzimba wevalve unentambo okanye intambo yombhobho, edityaniswe neflange yombhobho.

(2) Ivalve yokudibanisa eFlenge: umzimba wevalvu unepleyiti yeflange, edityaniswe neflange yombhobho.

(3) i-valve yokudibanisa i-welding welding yombane: umzimba we-valve uqulethe i-welding welding seam, kunye noqhagamshelo lombhobho we-welding.

(4) Ivalve yoqhagamshelo lwevalvu: umzimba wevalvu uqulethe ibamba kwaye uqhagamshelwe ngesibambeli sombhobho.

(5) Uhlobo lomkhono wevalve yokudibanisa edibeneyo: kunye nokukhethwa kombhobho we-sleeve yohlobo lokudibanisa ngokubambisana.

(6) Ivalve yoqhagamshelo lweWafer: imowudi yoqhagamshelo ethi isivalo kunye nemibhobho kumacala omabini ibotshelelwe kunye ngokukhawuleza ngebhawuli yasemhlabeni.

8, ngokwesixhobo somzimba wevalvu

(1) Ivalve yentsimbi: umzimba wevalvu kunye namanye amalungu enziwe ngezinto zentsimbi. Okufana nevalve yentsimbi yehagu, ivalve yentsimbi yekhabhoni, ivalve yentsimbi yealloy, ivalve yobhedu yealloy, ivalve yeprofayili yealluminiyam, ivalve yealluminiyam, ivalve yetitanium, ivalve yeMonel alloy, njl.

(2) ivelufa engeyiyo intsimbi: umzimba wevalvu kunye namanye amalungu enziwe ngezinto ezingezizo ezentsimbi. Njengevalve yeplastiki, ivalve yeceramic, ivalve enemigca, ivalve ye-FRP anticorrosive, njl.

(3) ivelufa yentsimbi yomzimba ivelufa: uyilo lwenkangeleko yevalvu yomzimba wesixhobo sesinyithi, ulwakhiwo lwangaphakathi apho ukudibana nendawo ikakhulu ilucwecwe lomphezulu, njengosasazo lweoyile, ivelufa yeplastiki, ivelufa yeseramikhi, njl.

Eyesibini, ukusebenza kwevalvu yezityalo zekhemikhali

Vula kwaye uvale uhlobo: qhawula okanye unxibelelane ngobumanzi bolwelo kumbhobho we-ac;

Ukulungelelanisa uhlobo: lungisa umlinganiselo wokuhamba kunye nesantya sokuhamba kwi-tube;

Uhlobo lwevalve ye-Throttle: yenza ulwelo ngokwevalve emva kokubangela uxinzelelo olukhulu kakhulu lwegesi;

Ezinye iintlobo: a. ukuvulwa nokuvala okuzenzekelayo ngokupheleleyo B. ukugcina uxinzelelo oluthile lokusebenza C. umbhobho wokuvalela umphunga.
