Taw qhia rau daim ntawv thov, cov khoom tseem ceeb thiab cov yam ntxwv ntawm lub wafer dual phaj check valve

Waferdual phajkos valveyog hais txog lub valve uas cia li qhib thiab kaw lub valve nrov plig plawg los ntawm kev cia siab rau qhov ntws ntawm qhov nruab nrab nws tus kheej kom tsis txhob rov qab los ntawm qhov nruab nrab, tseem hu ua check valve, ib-txoj kev valve, thim rov qab ntws valve thiab rov qab siab valve.Waferdual phajkos valveyog lub valve tsis siv neeg uas nws lub luag haujlwm tseem ceeb yog los tiv thaiv qhov rov qab ntawm qhov nruab nrab, tiv thaiv qhov rov qab tig ntawm lub twj tso kua mis thiab lub cev muaj zog, thiab tso tawm qhov nruab nrab hauv lub thawv.Waferdual phajcheck li qub kuj tseem siv tau rau ntawm cov kab uas muab cov khoom pabcuam uas lub siab tuaj yeem nce siab tshaj qhov system siab.

 

1. Wafer hom ob lub phaj kos valve daim ntawv thov:

Waferdual phajkos valveyog ntsia rau hauv lub raj xa dej, thiab nws txoj haujlwm tseem ceeb yog los tiv thaiv qhov rov qab ntawm qhov nruab nrab.Lub waferdual phajkos valveyog lub valve tsis siv neeg qhib thiab kaw nyob ntawm qhov nruab nrab siab.Wafer homdual phajkos valveyog haum rau nominal siab PN1.0MPa ~ 42.0MPa, Class150 ~ 25000;nominal txoj kab uas hla DN15 ~ 1200mm, NPS1/2 ~ 48;ua hauj lwm kub -196 ~ 540 ℃ ntawm ntau yam kav dej, siv los tiv thaiv backflow ntawm nruab nrab.Los ntawm kev xaiv cov khoom sib txawv, nws tuaj yeem siv rau ntau yam xov xwm xws li dej, chav dej, roj, nitric acid, acetic acid, muaj zog oxidizing nruab nrab thiab uric acid.

 

2. Cov khoom tseem ceeb ntawm waferdual phajcheck valve:

Muaj cov pa roj carbon steel, qis kub hlau, dual theem steel (F51 / F55), titanium alloy, txhuas bronze, INCONEL, SS304, SS304L, SS316, SS316L, chrome molybdenum steel, Monel (400/500), 20 # alloy, Hastelloy thiab lwm yam khoom siv hlau.

 

3. Cov yam ntxwv ntawm tus qauvdual phajcheck valve:

1. Cov qauv ntev yog luv, thiab nws cov qauv ntev tsuas yog 1/4 ~ 1/8 ntawm cov tsoos flanged.viav viaskos valve.

2. Me me thiab lub teeb yuag, nws qhov hnyav tsuas yog 1/4 ~ 1/20 ntawm cov tsoos flangedviav viaskos valve.

3. Lub valve disc kaw sai thiab cov dej rauj siab me me

4. Ob txoj kab kab rov tav lossis ntsug kav siv tau, yooj yim rau nruab

5. Lub ntws channel yog du thiab cov kua dej tsis kam yog me me

6. Kev ua haujlwm siab thiab ua haujlwm zoo sealing

7. Lub valve disc mus ncig yog luv luv thiab lub zog kaw yog me me

8. Tag nrho cov qauv yog yooj yim thiab compact, thiab cov duab zoo nkauj

9. Lub neej ua haujlwm ntev thiab txhim khu kev qha

 

Plaub, qhov kev ua txhaum ntawm covdual phajcheck valve yog:

1. Lub valve disc tawg

Lub siab ntawm nruab nrab ua ntej thiab tom qab lubdual phajkos valveyog nyob rau hauv lub xeev ntawm kev sib npaug sib npaug thiab kev sib nrig sib "pom".Lub valve disc feem ntau raug ntaus nrog lub rooj zaum valve, thiab lub valve disc ua los ntawm qee cov ntaub ntawv nkig (xws li cam khwb cia hlau, tooj dag, thiab lwm yam) raug ntaus.tawg.

Txoj kev tiv thaiv yog siv adual phajkos valve nrog lub disc ua cov khoom siv ductile.

2. Nruab nrab rov qab

Lub sealing nto puas lawm;impurities raug kaw.

Los ntawm kev kho lub sealing nto thiab ntxuav impurities, backflow tuaj yeem tiv thaiv.
