Taw qhia rau kev siv, cov khoom tseem ceeb thiab cov yam ntxwv ntawm cov wafer kos valve

Kuaj 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, rov qab ntws valve thiab rov qab siab valve.Lub pob valve yog lub valve tsis siv neeg uas nws lub luag haujlwm tseem ceeb yog los tiv thaiv qhov rov qab ntawm qhov nruab nrab, qhov rov qab tig ntawm lub twj tso kua mis thiab lub cev muaj zog tsav tsheb, thiab qhov tso tawm ntawm lub thawv nruab nrab.Kos li qub kuj tseem siv tau rau ntawm cov kab uas muab cov cuab yeej pabcuam uas lub siab tuaj yeem nce siab dua qhov system siab.

1. Wafer kos valve daim ntawv thov:

Lub check valve yog ntsia rau hauv cov kav dej, thiab nws txoj haujlwm tseem ceeb yog los tiv thaiv qhov rov qab ntawm qhov nruab nrab.Lub pob valve yog lub valve tsis siv neeg qhib thiab kaw nyob ntawm qhov siab ntawm qhov nruab nrab.Wafer check 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 pipelines, siv los tiv thaiv Medium backflow.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.

Thib ob, cov khoom tseem ceeb ntawm wafer kos valve: 

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

3. Cov yam ntxwv ntawm wafer kos valve:

1. Cov txheej txheem ntev yog luv, thiab nws cov qauv ntev tsuas yog 1/4 ~ 1/8 ntawm cov tsoos flange kos valve

2. Qhov loj me thiab lub teeb yuag, nws qhov hnyav tsuas yog 1/4 ~ 1/20 ntawm cov tsoos flange kos 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 txiav txim siab zoo thiab kev sib khi zoo

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

Thib plaub, cov kev ua txhaum ntau ntawm cov tshev valve yog:

1. Lub valve disc tawg

Lub siab ntawm qhov nruab nrab ua ntej thiab tom qab kos valve yog nyob rau hauv lub xeev ntawm qhov 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 yam khoom siv (xws li cam khwb cia hlau, tooj dag, thiab lwm yam) tawg.Txoj kev tiv thaiv yog siv lub tshev valve nrog lub disc ua cov khoom siv ductile.

2. Nruab nrab rov qab

Lub sealing nto yog puas;impurities raug kaw.Los ntawm kev kho lub sealing nto thiab ntxuav impurities, backflow tuaj yeem tiv thaiv.
