Bonnetless Lub Ntiaj Teb Valve Cov Lus Qhia
Bonnetless ntiaj teb valve yog ib lub valve uas tshem tawm cov kev pheej hmoo ntawm kev ua kom zoo nkauj {} Nws yog qhov kev ua tiav ntawm kev ntseeg siab, xws li lub zog thiab petrochemical .
Tus qauv thiab tsim cov yam ntxwv
Sib xyaw lub cev lub cev:
Lub cev lub cev thiab lub zog sib khi yog forged lossis nrum raws li tag nrho, tsis muaj tus qauv ywj pheej, uas tau tshem tawm cov kev pheej hmoo ntawm lub cev lossis xov txuas ntawm lub cev valve;
Lub rooj zaum theem ob (xws li stepped valve lub rooj) yog saws kom txo qhov nruab nrab ntawm lub valve disc seft nto thiab txuas ntxiv kev pabcuam lub neej .
Foob thiab xa khoom lag luam:
Sealing nto: lub rooj valve thiab valve lub rooj yog welded nrog nyuaj alloy), nrog lub hardness ntawm ntau dua los yog sib npaug yog txhim kho los ntawm ntau dua 3 zaug;
Tem Los Ua Ke: Qhov saum npoo ntawm cov stainless hlau qia (xws li 17-4 pH) yog qhov sib zog ua kom haum rau qhov kub thiab txias kom haum rau qhov kub thiab txias .

Bonnetless ntiaj teb Valve
Cov Ntawv Thov:
Kev kub-kub thiab cov pa hluav taws xob siab hnyav:
Kev cais tawm ceev ntawm cov raj kav dej loj ntawm cov nroj tsuag thermal ntawm cov khoom siv hluav taws xob, nrog rau kev zam ntawm kev ua haujlwm ntawm kev sib koom ua ke ntawm kev sib sau ua ke valges;
Corrosive Media Control:
Cov inlet thiab qhov hluav taws xob qub ntawm cov tshuaj tua kab ntawm cov nplaim hluav taws xob yog qhov tsim nyog rau 42mpa kom haum rau 42mpa kom haum rau 42mpa kom muaj kev kub ntxhov, thiab tsis muaj cov ntaub ntawv tsis zoo ntawm cov chaw seem;

Kev Sib Piv Nrog Cov Chaw Ua Si Li Qub
| Cov Khoom Sib Piv | Bonnetless ntiaj teb Valve | Pa Lub Ntiaj Teb Valve (nrog Bonnet) |
|---|---|---|
| Sealing kev pheej hmoo | Tsis muaj sab nraud topage point (valve lub cev sib xyaw ua ke), tus nqi to tsawg dua lossis sib npaug nrog 0.001% dn | Flange / cov xov xwm sib txuas tau nquag toast (tolekage tus nqi yog li 0.01% dn) |
| Lub Zog Txheej Txheem | 6 lub sij hawm cov nominalv iab cov kabmob muaj peev xwm (ntsuas qhov kub thiab txias) | Cov pa 4 zaug kuaj xyuas siab (ASME B16.34 txuj ci) |
| Kev teeb tsa nyuaj | Tsis tas yuav muab lub pob txha duav teeb tsa, txo lub sijhawm los ntawm ntau dua 30% | Lub ntsej muag ntawm lub bonnet flange xav tau kom muaj txiaj ntsig |
| Siv tau kub | {{0-196℃~ 650℃(kaw lus hlau sealing) | {{0-29℃~ 550℃(txwv los ntawm valve npog gasket) |
