API Standard B367 Gr.C-2 Worm Gear Operated Metal ehleli Ball Valve

Ibhola yevalve yebhola edadayo iyadada, kwaye phantsi koxinzelelo lwendlela ephakathi, ibhola inokuvelisa indawo ethile kwaye icinezele ngokuqinileyo kwindawo yokutywina yesiphelo sokuphuma, iqinisekisa ukutywinwa kwesiphelo sokuphuma. Ivalve yebhola edadayo inesakhiwo esilula kunye nokusebenza kakuhle kokutywinwa, kodwa ibhola ithwala wonke umthwalo wendlela yokusebenza kwaye idluliselwe kumsesane wokutywina wokuphuma. Ngoko ke, kuyimfuneko ukuqwalasela ukuba izinto zokutywina ziyakwazi ukumelana nomthwalo osebenzayo webhola lebhola. Xa iphantsi koxinzelelo oluphezulu, ibhola inokuphambuka. Esi sakhiwo sisetyenziswa ngokubanzi kwiivalvu zebhola eziphakathi kunye neziphantsi.

Iimpawu eziphambili zevalve yebhola yinkqubo yayo edibeneyo, ukutywinwa okuthembekileyo, isakhiwo esilula, ukugcinwa okufanelekileyo, kunye nokutywinwa kwendawo kunye ne-spherical surface ihlala ivaliweyo, engenakuchithwa lula yi-medium. Kulula ukuyisebenzisa kunye nokugcinwa kwayo, ifanelekile kumajelo asebenza ngokubanzi njengamanzi, izinyibilikisi, iiasidi, kunye nerhasi yendalo, kwaye ifanelekile nakwiimeko zokusebenza ezinzima ezifana neoksijini, ihydrogen peroxide, i-methane, kunye ne-ethylene. Isetyenziswe ngokubanzi kumashishini ahlukeneyo. Umzimba wevalvu yevalve yebhola unokuba yinto edibeneyo okanye imodyuli.

- Ubungakanani ukusuka kwi-2 "ukuya kwi-8" (i-DN50mm ukuya kwi-DN200mm).
- Imilinganiselo yoxinzelelo ukusuka kwiKlasi ye-150LB ukuya kwi-600LB (PN10 ukuya kwi-PN100).

-Imowudi yokuqhuba inokuba yesandla, yombane, ipneumatic, okanye ixhotyiswe ngeqonga le-ISO.
- Intsimbi ekhandiweyo okanye imathiriyeli yentsimbi

1. Ukumelana nokuhamba kwevalve yebhola kuncinci. Xa i-valve yebhola egcweleyo ivuliwe, ishaneli yebhola, ishaneli yomzimba wevalve, kunye nedayamitha yombhobho odibanisayo iyalingana kwaye yenza i-diameter, kwaye i-medium ingahamba phantse ngaphandle kwelahleko.

2. I-valve yebhola inokuvalwa ngokupheleleyo kwaye ivuleke ngokupheleleyo ngokujikeleza i-90 °, ngokuvula ngokukhawuleza kunye nokuvala. Xa kuthelekiswa neevalvu zesango kunye neglowubhu yenkcazo efanayo, iivalve zebhola zinevolumu encinci kunye nobunzima obulula, okwenza kube lula ukuzifaka kwimibhobho.

3. Isihlalo esiphezulu se-valve: Isihlalo se-valve senziwe ngokusekelwe kwiminyaka yamava ekuveliseni i-valve yebhola, ukuqinisekisa ukutywinwa kwe-valve, i-coefficient ephantsi ye-friction, i-torque encinci yokusebenza, izixhobo zokuhlala ezininzi ze-valve, kunye noluhlu olubanzi lwezicelo.

4. Impazamo yokutshintsha i-free switch handle: usebenzisa i-stem ye-valve yentloko ye-flat, ukudibanisa kunye nesibambo akuyi kulungelelaniswa, ukuqinisekisa ukuba isimo sokutshintsha esibonakaliswe sisiphatho sihambelana neso sivalo.

5. Isixhobo sokutshixa: Ukuthintela ukungasebenzi kakuhle kokuvula nokuvalwa kwevalvu, kukho imingxuma yokutshixa kwiindawo ezivuleke ngokupheleleyo nezivalwe ngokupheleleyo zevalve ukuqinisekisa ukuba ikwindawo echanekileyo.

6. I-valve stem anti-flying structure: Isiqu sevalve sibekwe ezantsi ukuthintela uxinzelelo lokubhabha ngaphandle. Kwangaxeshanye, inokwenza ukudibana kwentsimbi kunye nomzimba wevalvu emva komlilo, iqinisekise ukuba isiqu sevalve sitywiniwe.
