Ukusilela kulawulo lwamandla ombane

Ukungaphumeleli kokulawula uxinzelelo ngamanye amaxesha kwenzeka xa kusetyenziswa ivalve yokuphuphuma. Kukho izinto ezimbini zokungaphumeleli kokulawulwa koxinzelelo lwevalve yoncedo lolingo: enye kukuba uxinzelelo alunakusekwa ngokuhlengahlengisa i-handwheel yokulawula uxinzelelo, okanye uxinzelelo alukwazi ukufikelela kwixabiso elilinganisiweyo; Enye indlela kukulungelelanisa uxinzelelo lwesondo ngaphandle kokuwa, okanye ukwandisa uxinzelelo ngokuqhubekayo. Kukho ezinye izizathu zokungaphumeleli kolawulo loxinzelelo, ngaphandle kwe-radial clamping ye-valve core ngenxa yezizathu ezahlukeneyo:

Okokuqala, i-damper yomzimba omkhulu wevalve (2) ivaliwe, kwaye uxinzelelo lwe-oyile alukwazi ukuhanjiswa kwigumbi eliphezulu levalve ephambili kunye negumbi elingaphambili levalve yokulinga, ukuze ivalve yokulinga ilahlekelwe ngumsebenzi wayo wokulawula ivalve. uxinzelelo lwevalve ephambili. Ngenxa yokuba akukho xinzelelo lweoyile kwigumbi eliphezulu levalve ephambili kwaye amandla entwasahlobo ancinci kakhulu, ivalve ephambili iba yivalve esebenza ngokuthe ngqo enegunya elincinci lentwasahlobo. Xa uxinzelelo kwi-oil inlet room luphantsi kakhulu, i-valve enkulu ivula i-valve yokunceda kwaye inkqubo ayinakukwazi ukwakha uxinzelelo.

Isizathu sokuba uxinzelelo lungakwazi ukufikelela kwixabiso elilinganisiweyo kukuba intwasahlobo yokulawula uxinzelelo ikhubazekile okanye ikhethwe ngokungalunganga, ukunyanzeliswa koxinzelelo loxinzelelo lokulawula intwasahlobo akwanelanga, ukuvuza kwangaphakathi kwevalve kukhulu kakhulu, okanye i-valve ye-cone. yevalve yokulinga inxibe ngokugqithisileyo.

Okwesibini, i-damper (3) ivaliwe, ukwenzela ukuba uxinzelelo lweoli alukwazi ukuhanjiswa kwi-valve ye-cone, kwaye i-valve yomqhubi we-pilot ilahlekelwa ngumsebenzi wokulungelelanisa uxinzelelo lwe-valve engundoqo. Emva kokuba i-damper (i-orifice) ivaliwe, i-valve ye-cone ayiyi kuvula i-oyile ephuphumayo phantsi kwayo nayiphi na ingcinezelo, kwaye akukho mafutha ahamba kwi-valve ngamaxesha onke. Uxinzelelo kumagumbi aphezulu nangaphantsi kwevalve ephambili ihlala ilingana. Ngenxa yokuba indawo yokuthwala i-annular ekupheleni kweyona nto iphambili ye-valve core inkulu kunokuba iphantsi, i-valve engundoqo ihlala ivaliwe kwaye ayiyi kudlula, kwaye uxinzelelo lwe-valve engundoqo luya kwanda ngokunyuka komthwalo. Xa i-actuator iyeka ukusebenza, uxinzelelo lwenkqubo luya kunyuka ngokungenasiphelo. Ukongeza kwezi zizathu, kuseyimfuneko ukujonga ukuba i-port yangaphandle yokulawula ivaliwe kwaye ingaba i-valve ye-cone ifakwe kakuhle.
