Uyini umgomo wokusebenza nokusetshenziswa kwe-kelly valve?

1. Inhloso ye-kelly valve

I-valve ye-kelly iyivalvu yokulawula eyenziwa ngesandla ohlelweni lokujikeleza kwezintambo zokubhola futhi ingelinye lamathuluzi asebenzayo okuvimbela ukuvuthuza. Ama-valve e-Kelly angahlukaniswa abe ama-kelly valve aphezulu kanye nama-kelly valves aphansi. I-valve ye-kelly engenhla isetshenziswa phakathi komkhawulo ongezansi we-faucet kanye ne-kelly; i-valve ye-kelly ephansi isetshenziswa phakathi komkhawulo ophansi we-kelly kanye nejoyinti lokuvikela i-kelly. Uketshezi lokumba lungageleza ngokukhululekile ku-valve ye-kelly ngaphandle kokwehla kwengcindezi. Sebenzisa isikrufu esikhethekile ukuze usivule sibe ngu-90° ngokwemiyalelo yokusivula nokusivala.

2. Isakhiwo se-valve ye-Kelly kanye nesimiso sokusebenza

I-valve ye-kelly engenhla nengezansi yakhiwe ngomzimba, isihlalo sebhola esiphansi, isiphethu, ukhiye wokusebenza, i-valve yebhola, iringi evulekile yokugcina ibhola, isihlalo esiphezulu sebhola, umkhono wendandatho oyibambayo, iringi ebambayo enwebekayo kanye nophawu. , i-accessory wrench, njll. Isimiso sokuvala ukuthi isiphethu sisekela isihlalo sebhola ukuze simise ibhola futhi silenze libe nokulayisha kuqala okuthile. Ibhola kanye nophawu lwesihlalo sebhola kusondelene. Lapho ibhola likhishwa, amehlo amanzi awavimbekile. Lapho ivaliwe, indawo eyindilinga ivala wonke amehlo amanzi. Ukucindezela kwe-annulus yangaphakathi kusebenza ebholeni, okwenza ibhola nesihlalo sebhola sibe sesimweni sokuvala ingcindezi ephezulu.

3. Indlela yokusebenzisa i-valve ye-kelly

(1) Ngaphambi kokusetshenziswa, sebenzisa isikrufu esikhethekile ukuzungezisa ukhiye wokusebenza ukuze ubone ukuthi ungakwazi yini ukuzungeza ngendlela eguquguqukayo, endaweni noma ngaphandle kwendawo;

(2) Ngemva kokuxhuma iziphetho ezingenhla nezingezansi ze-kelly, sebenzisa isikrufu futhi ukuze uhlole ukuguquguquka kwezikhiye zokusebenza ngaphambi kokwehla emthonjeni;

(3) Uma kukhahlelwa noma kuqhunyiswa i-kelly emthonjeni, i-valve yepulaki engaphezulu noma engezansi ye-kelly kufanele ivalwe endaweni eseduze;

(4) Ngesikhathi sokusebenza okuvamile, vala i-valve yepulaki engezansi ngaphambi kokuthulula i-kelly ukuze uvimbele uketshezi lokumba lungachaphazeli endaweni yokubhoboza;

(5) Phikelela ekuvuleni nasekuvaleni amaqhude angenhla nangaphansi kwe-kelly njalo. Isibonelo, lapho uxhuma ucezu olulodwa noma usebenzisa amaqhude angenhla naphansi e-kelly ngezikhathi ezithile, ukugwema ukugqwala nokungakwazi ukuvula nokuvala ngokujwayelekile;

(6) Ngemva kokuxhuma ucezu olulodwa, i-valve yepulaki evaliwe kufanele ivulwe ngesikhathi ukuze kugwenywe ukubamba iphampu lapho uqala iphampu;

(7) Isikrufu sevalvu yepulaki kufanele sibekwe kude nomthombo ukuze singaweli emthonjeni noma ilahleke;

(8) Lapho ukhetha i-valve yepulaki, qinisekisa ukuthi umfutho wayo omkhulu wokusebenza uhambisana nezinga lokucindezela leqembu elivimbela ukuvuthwa kwe-wellhead.
