Competitive Advantage
| Cov khoom sib piv | Cov khoom sib piv | Ductile Iron Mos Sealed Non-Rising Stem Gate Valve | Cov yam ntxwv ntawm cov neeg sib tw | Summary of Core Advantages |
|---|---|---|---|---|
| Sib piv nrog Steel Gate Valve | Anti-corrosion thiab Durability | Integrally nrum yam tsis muaj vuam seams. Mature integral epoxy anti- kev kho corrosion tiv thaiv corrosion los ntawm cov dej hauv av thiab dej phwj tuaj, tsis txhob xeb thiab perforation thaum lub sij hawm ntev - kev pab cuam. | Steel rooj vag li qub feem ntau yog welded. Weld seams yog cov ntsiab lus tsis muaj zog ua rau xeb, corrosion thiab to; txheej peeling yuav tsum tau saib xyuas tsis tu ncua. | Tsis muaj kev pheej hmoo zais ntawm vuam corrosion, kev saib xyuas tsawg tshaj plaws ntawm kev pab cuam lub neej thiab superior durability. |
| Vibration Resistance | Ductile hlau nta zoo toughness thiab damping kev ua tau zoo. Nws hloov mus rau ntev - lub sij hawm vibration ntawm cov twj tso kua dej; valve lub cev thiab cov qauv sealing nyob twj ywm yam tsis tas yuav xoob lossis tawg kom tsis txhob muaj kev vibration -induced to. | Steel li qub muaj siab rigidity tab sis tsis zoo damping. Ntev - lub sij hawm twj tso kua mis vibration yooj yim ua rau weld tawg thiab xoob pob qij txha ua rau dej to. | Zoo tshaj los tiv thaiv-kev co thiab tiv thaiv- qaug zog muaj peev xwm, deb dua haum rau cov chaw nres tsheb twj tso kua mis. | |
| Kev Pabcuam thiab Tus Nqi Tag Nrho | Standard loj- tsim cov khoom tiav nrog cov khoom txaus txaus thiab lub sij hawm luv luv, txo qis kev yuav khoom thiab kev tsim kho tag nrho. | Steel rooj vag li qub feem ntau yog kev cai- ua nrog lub voj voog ntau lawm thiab tus nqi siab, ua rau tus nqi hnyav thiab lub sijhawm teem sijhawm. | Kev xa khoom sai thiab tus nqi siab ua haujlwm, txiav qhov project ncua sij hawm thiab kev yuav khoom. | |
| Sib piv nrog Plastic Gate Valve | Structure Load Stability | High rigidity thiab load peev xwm. Tsis muaj deformation los yog tawg nyob rau hauv faus backfill thiab tsheb thauj khoom; kev ua haujlwm ruaj khov txawm tias qhov loj me DN300 thiab siab dua. | Yas rooj vag li qub tsis muaj rigidity thiab deform yooj yim nyob rau hauv extrusion. Qhov loj me muaj qhov tsis zoo siab tsis kam, ua rau txoj kab uas hla shrinkage thiab vau, tsis haum rau hnyav - cov kav dej kav dej. | Kev ua tau zoo nyob rau hauv qhov hnyav thiab loj - txoj kab uas hla rau kev ua haujlwm ruaj khov. |
| Kub thiab kev nyab xeeb kev ua haujlwm | Kub kub resistant thiab tsis yog -flammable. Haum rau kev ua haujlwm tshwj xeeb xws li kev lag luam siab - qhov kub thiab txias ntawm cov dej ntws thiab hluav taws kub, tsis muaj softening lossis deformation nyob rau hauv qhov kub thiab txias. | Plastics muaj qhov tsis zoo thaum tshav kub kub thiab yog cov nplaim taws. Lawv soften thiab deform nyob rau hauv cov dej kub nrog hluav taws kub, txwv siv tej yam kev mob. | Kev siv dav dua, muaj kev nyab xeeb dua nrog kev kub siab ua haujlwm thiab nplaim hluav taws kub. | |
| Kev tsim kho kev puas tsuaj | High hardness, hnav thiab cuam tshuam resistant. Hardly puas thaum lub sij hawm backfilling thiab txhua yam kev sib cuag nrog tsis tshua muaj qhov project poob tus nqi. | Cov khoom siv yas mos tau yooj yim khawb thiab khawb los ntawm cov pob zeb thiab cov tshuab, ua rau muaj kev puas tsuaj zais thiab cov khoom seem siab thaum lub sij hawm tsim kho. | Impact thiab hnav resistant, siab dua kev tsim kho kam rau ua thiab txo qhov project poob nqi. |
Ntsiab nta
Tag nrho lub rooj vag disc yog tag nrho nrog EPDM roj hmab. Nws ua tiav xoom-tawg kaw-tawm qhov xwm txheej, ua tau zoo dua lub qhov rooj qhov rooj nyuaj hauv kev sib khi. Tsis tshua muaj kev sib txhuam tshwm sim thaum hloov txav, kev tuav tes tuav lub teeb thiab du; hluav taws xob actuator adaptation yog txaus siab. Rubber cushion absorbs cuam tshuam thaum lub zog txav, muab kev tiv thaiv rau cov kav dej txuas thiab cov twj tso kua mis.
Tshwj xeeb tsim nyog rau qhov tsis-nce-stem layout
Cov qia yuav tsis ncab tawm sab nraud. Nws occupies tsawg tsawg qhov chaw sab hauv lub valve chamber, uas ua rau installation ua tau rau nqaim valve pits. Cov qia zaum hauv lub cev valve, kom deb ntawm cov av sib xyaw thiab hauv pas dej. Corrosion thiab jamming txaus ntshai rau qia tau txo, haum rau underground installation. Tsis muaj kev tshem tawm ntsug ntxiv rau kev nqa nqa tom qab faus, yog li kev nqis peev hauv kev tsim vaj tsev tuaj yeem txo qis.
Txoj Cai Ua Haujlwm
Gate disc nqa tawm ntsug linear txav ua ke nrog qia. Cov xov yog machined ntawm qia. Thaum lub log tig tig, cov ntsia hlau ntsia saum toj kawg nkaus tsav qia mus rau vertically raws li valve-lub cev qhia grooves, thiab rooj vag disc txav synchronously. Lub rooj vag kev coj mus ncig ua rau perpendicular mus rau nruab nrab ntws kev taw qhia hauv cov kav dej.
Cov yam ntxwv zoo
Rau qhov no concealed-stem soft-seal gate valve, qia thiab kis tau tus mob yog ob qho tib si tso rau hauv lub cev valve thiab tau raug rau cov txheej txheem nruab nrab ncaj qha. Cov txheej txheem zoo li no ua rau muaj kev pheej hmoo corrosion rau qia. Lub valve tsuas yog ua haujlwm nyob rau hauv tag nrho-qhib lossis kaw tag nrho; Nws yuav tsum tsis txhob siv rau lub hom phiaj ntws throttling. Thaum qhib tag nrho, ntws tsis kam hla lub valve mus txog qhov tsawg kawg nkaus tus nqi.
Daim ntawv thov Scenario
Txwv qhov chaw installation
Cov yeeb nkab gallery, trenches, underground valve chambers. Tsau tag nrho qhov siab zam kev sib tsoo tiv thaiv sab saum toj obstacles.
Kev ruaj ntseg siab
Sab nraum zoov thiab pej xeem-chaw installation; zais qia qauv tiv thaiv tib neeg tsim kev puas tsuaj tampering.
Lub hom phiaj kev lag luam
Cov kav dej tua hluav taws, cov chaw kho dej phwj tuaj, cov kav dej hauv nroog thiab lwm lub sijhawm uas qhov chaw txuag tseem ceeb.
