I-ZZYVP Pilot self-operated pressure regulator ingasebenza ngaphandle kukagesi nomoya.I-ZZYVP Pilot self-operated pressure regulator iwuhlobo lwevalvu yokulawula ingcindezi eyonga amandla esebenzisa izinguquko ezizicindezelayo ze medium elungisiwe ukuze ibone ukulungiswa okuzenzakalelayo kanye nenani eliqhubekayo lokucindezela. ngemva kwe-valve.ZZYVP Pilot self-operated pressure regulator medium esebenzayo: igesi engagqwali.
I-ZZYVP Pilot self-operated pressure regulator ingasetha ingcindezi eqondiwe kumqondisi ngesikhathi sokusebenza, ngakho kulula, kuyashesha, ukonga umsebenzi futhi konga isikhathi.I-ZZYVP Pilot self-operated pressure regulator inokusabela Okuzwelayo, ingakwazi ukubona ukucindezela okuncane kanye noshintsho lwengcindezi (isb.50mm umfutho wekholomu yamanzi),isilinganiso sokuncibilika siphezulu, isilinganiso esiphezulu sokuwohloka singu-100:1lapho ingcindezi ngaphambi kwevalvu ingaphansi kuka-8bar.
I-ZZYVP Pilot self-operated pressure regulator iphindwe kabili kune-ZZY i-valve ezilawulayo ezisebenza yona, ikakhulukazi ngesikhathi sokuwohloka kwegesi, lapho ingcindezi ngaphambi kwe-valve ingu-1~8bar kanye nokucindezela ngemva kwevalvu ingaphansi kuka-15KPa.

Umdwebo wesakhiwo sesilawuli sengcindezi esizisebenzelayo somshayeli wendiza

Umgomo wokusebenza kwesilawuli sengcindezi esizisebenzelayo somshayeli

1.Ekuqaleni, i-spool enkulu ye-valve ye-ZZYVP Pilot yesilawuli sokucindezela esizisebenzelayo sihlala sivaliwe ngaphansi kwe-spring11 action force.Umqondisi 08 uhlala evulekile ngaphansi kwe-spring 17 action force.
2. I-medium igelezela ku-valve yokulawula ngaphansi kokuqondisa komcibisholo, ngevalvu yokukhulula engu-06, igeleze iye kumqondisi 08, ngomqondisi 08 kanye ne-throttle valve 13, igeleze iye ku-actuator 07 ekamelweni le-diaphragm ngezansi.Ingcindezi evela ku-actuator07 diaphragm ekamelweni elingezansi iyenyuka.I-valve eyinhloko izovuleka ngaphansi kwengcindezi.Into ephakathi igelezela kuvalvu, ngokucindezela u-09 kanye no-21, bese igelezela ku-actuator07 ekamelweni le-diaphragm ngenhla kanye nomqondisi 08 ekamelweni le-diaphragm ngaphezulu.
3.Lapho umfutho we-P2 ngemva kokukhuphuka kwe-valve, ingcindezi engu-P4 esebenza ku-actuator 07 ekamelweni le-diaphragm ngenhla iyakhuphuka, idigri enkulu yokuvula i-valve iyancipha futhi ingcindezi ngemva kokunciphisa i-valve (ukulungiswa kokuqala).Ngaleso sikhathi, ingcindezi engu-P6 esebenza kumqondisi wegumbi le-diaphragm engu-08 ngenhla iyakhuphuka futhi izinga lokuvula lomqondisi 08 liyehla.Ukucindezela okungu-P5 ku-actuator 07 egunjini le-diaphragm ngezansi kuyehla.I-ZZYVP Pilot self-operated pressure regulator idigri enkulu yokuvula i-valve iyehla ngokuqhubekayo futhi ingcindezi ngemva kwevalvu ilokhu yehla(ukulungiswa okuhle).
4.Lapho ukucindezela kwe-P2 ngemva kwe-valve kuncipha, ingcindezi engu-P4 esebenza ku-actuator 07 chamber diaphragm ngenhla iyanciphisa.Idigri yokuvula i-valve eyinhloko iyanda, futhi ukucindezela ngemva kokukhuphuka kwe-valve (ukulungiswa kokuqala).Ngaleso sikhathi, ingcindezi engu-P6 kumqondisi we-diaphragm engu-08 ngaphezulu iyehla, idigri yokuvula engumqondisi engu-08 iyakhula, futhi ingcindezi engu-P5 ku-actuator 07 yegumbi le-diaphragm ngezansi iyakhuphuka.Idigri enkulu yokuvula i-valve iyanda futhi ingcindezi ngemuva kwevalvu ilokhu ikhula (ukulungiswa okuhle).
5.I-spool ye-valve eyinhloko ye-ZZYVP Pilot isilawuli sokucindezela esizisebenzelayo kanye nomqondisi 08 ngeke siyeke ukusebenza size sifinyelele inani elimisiwe.Kulo mzuzu, ingcindezi ngemuva kwe-valve isethiwe inani, ukuwohloka okuguquguqukayo kungenziwa.
