Yiziphi Izinhlobo Zama-Valve: Ukuhlukaniswa Nokusetshenziswa Okuyi-8

Ama-valve ezinhlobo ezahlukeneyizingxenye zokulawula ezinhlelweni zokulethwa koketshezi, ezisetshenziswa kakhulu ukuvula nokuvala amapayipi, ukulawula isiqondiso sokugeleza, kanye nokulawula nokulawula amapharamitha endawo yokulethwa (njengokushisa, ingcindezi, kanye nokugeleza).

Izinhlobo Eziyi-8 Zamavalvu Ezimakethe Nephayiphi Ngokuyinhloko

Amavalvu Ebhola

Aivalvu yebholainokumelana okuncane kakhulu koketshezi phakathi kwazo zonkeizinhlobo zamavalvu, futhi ngisho nevalvu yebhola enobubanzi obuncishisiwe inokumelana okuncane koketshezi. Ingxenye yokuvula nokuvala yevalvu yebhola iyindilinga enembobo, ejikeleza i-axis eqondile kumzila ukuze kufezwe injongo yokuvula nokuvala umzila.

I-quarter-turnAmavalvu Ebhola Anezindlela Ezimbiliyiwona uhlobo oluvame kakhulu lwevalvu yokulawula inqubo. Amavalvu anezindlela ezimbili (ukungena kanye nokuphuma), anezindawo ezimbili (ezivulekile nezivaliwe) asetshenziselwa ukuvala noma ukuhlukanisa izinhlelo, amasekethe noma izingxenye ngaphakathi kwesistimu.

Amavalvu e-plug

Ipulaki yevalvu yepulaki ngokuvamile iyisilinda noma iyindilinga, futhi ukuma kwesiteshi kungaba unxande noma i-trapezoidal njengoba kudingeka. Le valve inesakhiwo esilula, ukushintsha okusheshayo, ukumelana noketshezi okuphansi, futhi kulula ukuzivumelanisa nezakhiwo zeziteshi eziningi.

Amavalvu okuxhuma ngokuvamile asetshenziselwa ukusika nokuxhuma imidiya, kanye nokuguqula ukugeleza, kodwa angasetshenziswa futhi ekugoqeni. Njengoba umzimba wokuxhuma wevalvu yokuxhuma ujikeleza nesiqu sevalvu ukuze kufezwe isenzo sokuvula nokuvala, angasetshenziswa futhi nakuma-media anezinhlayiya ezilengayo.

I-Butterfly Valve

Iivalvu yebhabhathaneiyivalvu evamile yokulawula ukugeleza. Umgomo wayo osebenzayo ukulawula ukugeleza koketshezi ngokulungisa indawo yevemvane. Lapho ivemvane lijikeleza, uketshezi lushintsha indawo yalo phakathi kwevemvane, ngaleyo ndlela lushintsha usayizi wokugeleza.

Idiski yevalvu ijikeleza ngama-90° ngaphakathi kwebanga lesihlalo sevalvu ukuze kufezwe ukuvulwa nokuvalwa kwevalvu.

I-Valve yeSango

Ingxenye yokuvula nokuvala ye-ivalvu yesangoyisango. Indlela yokuhamba kwesango iqonde ngqo ohlangothini loketshezi. Ivalvu yesango ingavulwa ngokugcwele futhi ivalwe ngokuphelele, futhi ayikwazi ukulungiswa noma ukugoqwa.

Isango linezindawo ezimbili zokuvala. Izindawo ezimbili zokuvala zevalvu yesango yemodi esetshenziswa kakhulu zakha isimo se-wedge, futhi i-engeli ye-wedge iyahlukahluka ngokwemingcele yevalvu.

I-Globe Valve

Umgomo osebenzayo wevalvu yomhlaba ukuthembela ekucindezelweni kwesiqu sevalvu ukwenza indawo yokuvala idiski yevalvu ivumelane eduze nendawo yokuvala isihlalo sevalvu ukuvimbela ukugeleza kwe-medium. Uma ivalvu ivaliwe, ingcindezi kumele ifakwe kudiski ukuze kuphoqwe indawo yokuvala ukuthi ingavuzi.

Amavalvu e-globe afaneleka kokubili ukusetshenziswa kokuvula/ukuvala kanye nokucindezela. Amavalvu e-globe anezindlela ezimbili ayathandwa ukuze kulawulwe ukugeleza okunembile, kanti amavalvu e-globe anezindlela ezintathu avame ukusetshenziselwa ukuxuba imidiya evela emithonjeni emibili bese eqondisa ingxube endaweni yokukhipha amanzi.

Amavalvu Enaliti

Lawa ma-valve afana kakhulu nama-globe valve, kodwa anomehluko emibili emikhulu. Okokuqala, mancane, angalawula kangcono ukugeleza kwe-flow emigqeni emincane. Okwesibili, asebenzisa “inaliti” eqondile esikhundleni se-plug efana ne-disc kanye ne-orifice nenaliti valve ukulawula ukugeleza okunembile.

Amavalvu e-Solenoid

Ama-valve e-Solenoid asebenza ngokudlulisa ugesi nge-coil, okubangela ukuthi i-coil ikhiqize insimu yamagnetic, esebenza enkabeni yensimbi ukuze ikhiqize ukukhanga kwamagnetic, bese i-iron core iqhubekela enkabeni ye-coil, okwenza i-valve ivuleke.

Amavalvu e-Solenoid mancane kakhulu. Usayizi wawo unqunyelwe amandla e-coil, okuwumphumela wokugoqa okusetshenziselwa ukukhiqiza insimu yamagnetic uma inikwa amandla. Ngaphezu kokukhawulelwa kwamandla e-coil, indlela yokugeleza kanye ne-orifice ku-valve ye-solenoid nakho kuncane kakhulu uma kuqhathaniswa nosayizi wephayiphi.

I-Angle Piston Valve

I-valve ye-piston ye-angle uhlobo olukhethekile lwe-valve ene-actuator ye-pneumatic eyakhelwe ngaphakathi futhi ivame ukuhlukaniswa njenge-valve enezindawo ezimbili. I-actuator ingaba yi-spring return noma i-double acting, kuye ngezidingo zesicelo.

Ingxenye ebalulekile ku-valve yi-valve plug, ebekwa emgudwini wokugeleza nge-engeli ethile futhi ihlezi esihlalweni se-valve esithambekele esibunjwe endleleni yokugeleza kwe-valve.

Uma ivalvu ivuliwe, ipulaki yevalvu icishe ihoxiswe ngokuphelele ngaphandle kwesiteshi sokugeleza. Lo mklamo uvumela ivalvu yepiston ye-angle ukuthi ibe nesivinini esikhulu sokugeleza kanye nokwehla kwengcindezi okuphansi, okwenza kube ivalvu esebenza ngokushesha. Ezinhlelweni eziningi zokuvula/ukuvala, amavalvu esihlalo se-angle ayisinqumo esingabizi kakhulu esingathatha indawo yamavalvu ebhola endabuko.

Isifinyezo

Kunezinhlobo eziningi zamavalvu, futhi ukwakheka kwamavalvu kuyahlukahluka ngokuya ngezimo zokusebenza ezahlukene kanye nezidingo zokusetshenziswa. Ngaphezu kwamavalvu ayi-8 asetshenziswa kakhulu okukhulunywe ngawo ngenhla, kunezinye izinhlobo eziningi zamavalvu, njengamavalvu epulaki, amavalvu okulawula, amavalvu okuvala, amavalvu e-HIPPS, njll.
