Ivalvu yevithamini ye-pneumaticyakhiwe mtjhini we-pneumatic kanye ne-valve ye-butterfly. Ivalvu yevivane yomoya isebenzisa ipuleti yevemvane eyindilinga ejikelezako nesiqu sevalvu ukuvula nokuvala, ukwenzela bona kufezwe isenzo sokusebenza. Ivalvu yomoya isetjenziswa khulu njengevalvu yokuvala, begodu ingaklanywa bona ibe nomsebenzi wokulungisa nofana ivalvu yesigaba nokulungiswa. Njenganje, i-butterfly valve isetjenziswa emtjhini ophasi begodu emikhulu Isetjenziswa khulu emaphayiphini ane-bore ephakathi.
Umthetho wokusebenza weivalvu yevivane yomoya
Ipuleti yevithamini yevalvu yevivane ifakwe ngendlela yobubanzi bephayiphi. Emseleni oyisilinda womzimba wevalvu yevivane, ipuleti levivane elibunjwe njengediski lijikeleza i-eksisi, begodu i-engele yokujikeleza iphakathi kuka-0°-90°. Lokha ukujikeleza nakufika ku-90°, ivalvu isebujamweni obuvulekileko. Ivalvu ye-butterfly ilula ngokwakhiwa, incani ngobukhulu begodu ilula ngobunzima, begodu ineengcenye ezimbalwa kwaphela. Ngaphezu kwalokho, ingavulwa msinya begodu ivalwe ngokujikeleza 90 kwaphela°, begodu ukusebenza kulula. Ngesikhathi esifanako, ivalvu ineemfanelo ezihle zokulawula uketshezi. Lokha i-valve ye-butterfly nayivuleke ngokupheleleko, ukujiya kwepuleti ye-butterfly ngikho kwaphela ukujamelana lokha umkhathi nawugeleza emzimbeni we-valve, ngalokho ukwehla komfutho okwenziwa yi-valve kuncani khulu, ngalokho ineemfanelo ezihle zokulawula ukugeleza. Amavalvu we-butterfly anemihlobo emibili yokuvala: ukuvala kwe-elastic nokuvala kwesimbi. Emavalvu wokuvala we-elastic, indandatho yokuvala ingafakwa emzimbeni wevalvu nofana inamathele emaphethelweni wepuleti yevithamini.
Ivalvu yevithamini ye-pneumaticukutlhogonyelwa nokulungisa amaphutha
1. Ihlelo lokuhlola nokugcina isilinda
Ngokuvamileko yenza umsebenzi omuhle wokuhlanza ingaphezulu lesilinda begodu ufake amafutha esiqhemeni seshafu yesilinda. Vula isivalo sokugcina sesilinda qobe ngemva kweenyanga ezisithandathu ukuhlola bona ingabe kunezinto ezihlukahlukeneko nomswakama ngaphakathi kwesilinda, nobujamo bamafutha. Nangabe amafutha wokuthambisa awasekho nofana womile, kuyatlhogeka bona kukhishwe isilinda ukulungiswa okupheleleko nokuhlanzwa ngaphambi kokufaka amafutha wokuthambisa.
2. Ukuhlolwa komzimba wevalvu
Njalo ngemva kweenyanga ezisithandathu, hlola bona ukubukeka komzimba wevalvu kulungile na, bona kukhona na ukuvuza e-flange yokufaka, nangabe kulula, hlola bona ukuvalwa komzimba wevalvu kuhle na, akukho ukuguga, bona ipuleti levalvu liguquguquka na, nokuthi ingabe kukhona into yangaphandle ebhajwe ngaphakathi kwevalvu.
Iindlela zokuhlukaniswa nokuhlanganisa ibhlogo yesilinda kanye namagadango wokuzivikela:
Kokuthoma susa isilinda emzimbeni wevalvu, qala susa isivalo emaphethelweni womabili wesilinda, tjheja indlela i-piston rack eqonde ngayo lokha nawususa ipistoni, bese usebenzisa amandla wangaphandle ukujikelezisa ishafti yesilinda ngendlela yewashi ukwenza ipistoni igijime iye ehlangothini elingaphandle, bese uvala ivalvu Umgodi ungena umoya kancanikancani begodu ipistoni ikhutjhwa kancanikancani, kodwana indlela le igandeleleka kufanele utjheje ukungenisa umoya kabuthaka, ngaphandle kwalokho ipistoni izokuphuma msinyana, okuyingozi kancani! Bese ususa isiqephu esisesigodini sesilinda, begodu isigodo sesilinda singavulwa ukusuka ngakelinye ihlangothi. likhuphe. Ngemva kwalokho ungahlanza ingcenye ngayinye bese ufaka amafutha. Iingcenye ezitlhoga ukugcotshwa ngilezi: udonga lwangaphakathi lwesilinda kanye nendandatho yokuvala yepistoni, i-rack nendandatho yangemuva, kanye neshafu yegiya nendandatho yokuvala. Ngemva kokuthambisa amafutha, kufanele afakwe ngokuya ngokulandelana kokudilizwa kanye nokulandelana okubuyela emuva kweengcenye. Ngemva kwalokho, kufanele ifakwe ngokuya ngokulandelana kokudilizwa nokulandelana okubuyela emuva kweengcenye. Tjheja ubujamo begiya ne-rack, begodu uqinisekise bona ipistoni incipha ibe sebujameni lapho ivalvu ivulekile. Umgodi osemphethweni ongaphezulu weshafu yegiya uhambisana nebhlogo yesilinda ngesikhathi sendawo engaphakathi khulu, begodu umgodi osekupheleni okuphezulu kweshafu yegiya uqondile ebhlokini lesilinda lokha ipistoni nayilulelwa endaweni engaphandle khulu lokha ivalvu nayivaliweko.
Ukufakwa kwesilinda nomzimba wevalvu neendlela zokulungisa amaphutha kanye namagadango wokuzivikela:
Kokuthoma faka i-valve ebujameni obuvaliweko ngamandla wangaphandle, okutjho bona, jika i-valve shaft ngokuya ngewashi bekube kulapho ipuleti ye-valve ithintana nokuvala isihlalo se-valve, begodu ngesikhathi esifanako faka isilinda ebujameni obuvaliweko (okutjho bona, i-valve encani engaphezulu kwe-valve shaft yesilinda I-groove iqondile emzimbeni wesilinda (ngombana i-valve ijikeleze nge-washi ukuvala i-valve), isilinda ukuya ku-valve (indlela yokufaka ingaba yi-parallel nofana ibe yi-perpendicular emzimbeni we-valve), bese uhlola bona iimbobo zesikrufu ziqondile na. i-muffler, njll., nangabe ayikapheleli, ungalungi, umfutho womoya ovamileko ngu-0.6MPA±0.05MPA, ngaphambi kokusebenza, yenza isiqiniseko sokobana akukho ukungcola okunamathele epuletini levalvu emzimbeni wevalvu Ekuqaliseni nokusebenza kokuthoma, sebenzisa ibhathini lokusebenza ngesandla levalvu ye-solenoid (ikhoyili yevalvu ye-solenoid icinywa ngesikhathi sokusebenza ngesandla, begodu ukusebenza ngesandla kuyasebenza; lokha nakwenziwa umsebenzi wokulawula igezi, ukujika ngesandla kusetjenziswe begodu ikhoyili isebenza ngesandla, begodu isebenza ngesandla iyasebenza; 0 isikhundla 1 kukuvala ivalvu, 1 kuvula ivalvu, okutjho bona, ivalvu ivulwa lokha nakuvulwa amandla, begodu ivalvu ivalwa lokha nakuvalwa amandla.
Nangabe kutholakala bona umenzi wevalvu ye-pneumatic butterfly uphuza khulu endaweni yokuthoma yokuvulwa kwevalvu ngesikhathi sokuthonywa nokusebenza, kodwana msinya khulu msinyana nasele ihamba. Msinyana, endabeni le, ivalvu ivaliwe khulu, vele ulungise i-stroke yesilinda kancani (lungisa iinkulufu zokulungisa i-stroke emaphethelweni womabili wesilinda kancani ngesikhathi sinye, lokha nawulungisako, i-valve kufanele ithuthelwe endaweni evulekileko, bese umthombo womoya kufanele uvaliwe Yivale bese ulungisa i-valve ize ivuleke endaweni ngaphandle kokuvuza. Nangabe i-muffler iyalungiswa, ijubane lokutjhuguluka kwevalvu lingalungiswa. Kuyatlhogeka ukulungisa isithunzi ukuvuleka okufaneleko kwejubane lokutjhugulula ivalvu. Nangabe ukulungiswa kuncani khulu, ivalvu ingahle ingasebenzi.
