Ivelufa Thulani-off amanzi kunye wamanzi medium

ivelufa Thulani-off yi isivingco esinenjongo nokukhubeka nkqi kumbhobho iphelele okanye inxalenye kwiimfuno zeteknoloji okanye ngamaxesha angxamisekileyo. main inzuzo wayo isantya, njengoko ekupheleni isixhobo intwasahlobo kubangelwa ngoko nangoko. Cocking spring olwenziwe ngumntu actuator yombane okanye womoya.

Thulani-off valve: uhlobo

Olu hlobo vana inokuba piston okanye uvalo actuator. Ngaphezu koko, ivelufa wavala-off angaba ukuya kwenye yezi ntlobo: ukunxibelelana, emboxo olunye okanye kabini isihlalo,. Ngendlela ukuvala olu hlobo unyanzeliso ngu: intwasahlobo, pneumatically, okanye umthwalo ezitshixwayo electromagnetically.

scope

Thulani-off vana kunye nomzimba propulsive ezisetyenziselwa ukuthutha le yintlama-esirhabaxa okanye osuleleke bume. Kule fowuni akukho imimandla amile. Steel ne shutoff vana emboxo piston ngamanzi ukuba nefuthe amabini, lisetyenziswa kwi imeko koxinzelelo oluphezulu.

Okwangoku, eli hlobo unyanzeliso inemisebenzi constructional hlobo ukuba ulawulo medium kuyo inkoliso isicelo ngenkuthalo umphunga. Loo ivelufa iyasebenza imizuzwana 1.5-10. cylinder Kwalo lwezindlu a gasket, inxeba, ukuza ezenziwe ngentsimbi, a umhlwa-enganyangekiyo, ngomaleko asbestos. Xa uthelekisa ne-bume lwangaphandle, yengxinano le hlobo vana kakhulu phezulu, okwenza ukuba ukungabi amatywina. Konke oku ngokubonakalayo ukwandisa ukuthembeka kwabo isebenza kunye zokuphucula ucikizeko lomsebenzi.

Thulani-off valve phezu kwamanzi; Ngokungafaniyo ukuguqulwa entsha endala

Uyilo olu hlobo unyanzeliso zatshintsha kakhulu, ngoko uyakwazi ukulandelela iiyantlukwano ezininzi ezibalulekileyo. Iimpawu ibalulekileyo iinguqulelo ezintsha zezi:

• anda ukumelana kungcoliseko;
• iqondo ingqibelelo;
• Ukuthembeka luyanda kangangoko kunokwenzeka;
• Isantya impendulo kudlula ukulungiswa endala;
• line kungenzeka ngeendlela ezimbini: phambili reverse.

Olu hlobo vana zisetyenziswa isizukulwana amandla, yintlama kunye namashishini iphepha kunye nokutya, kuquka unyango wamanzi kunye nokulungiselela yayo.

Iimfuneko izifakelelo wavala-off

Imfuneko engundoqo kule meko isantya impendulo. Ukuthobela oku kuphunyezwa ngokusixhobisa okanye ngaphezulu entwasahlobo vana. Ngokuqhelekileyo kwezoyilo ezinjalo, sebenzisa imithombo coil okanye Belleville. Xa usebenzisa i electric kuyilo actuator vana busenza ukuba ubukho latches ukuba ubambe emthonjeni ikwimeko cocked, nabo ilawulwa abasebenza. Zenzekelayo evale-off ivelufa izakufunyanwa ngephanyazo kwaye kanye njengokuba ngokukhawuleza ndiye kwimo yokulinda xa kuyimfuneko.

Zonke iintlobo ngeentlobo olu hlobo unyanzeliso zingenziwa ngezinto ezahlukeneyo ziintsimbi, iplastiki, intsimbi, uphoswe okanye insimbi.
