Pillar Hydrant Landing Valve Copper Alloy

1 Kev ua kom zoo tshaj plaws ntawm tooj dag

Lub cev lub cev tau txais kev sib koom ua ke ntawm kev thauj khoom-cov kabmob ntawm "valve kab noj hniav - valve qia - handwheel". Cov tooj dag tau txais "kev daws teeb meem + kev laus kev kho mob", uas ua rau lub matrix hardness ntawm HB110-130 thiab qhov kub thiab txias cuam tshuam toughness ntawm ntau dua los yog sib npaug rau 10J / cm² ntawm -20 degree, ua tau raws li British BS EN 14384 cov cai. Cov dej ntws tau txais qhov "kev sib cog lus tsim qauv" nrog rau sab hauv phab ntsa roughness ntawm Ra tsawg dua los yog sib npaug rau 1.2μm thiab qhov dej tsis kam coefficient tsawg dua lossis sib npaug li 0.8. Lub qhov hluav taws xob dej ntws mus txog 48m³ / h rau DN50 thiab 75m³ / h rau DN65, uas yog 10% siab dua li cov khoom zoo sib xws.

Lub qia valve yog ua los ntawm 2Cr13 stainless hlau nrog nyuaj chrome plating, nrog diameters ntawm 24mm (DN50) thiab 28mm (DN65) feem. Nruab nrog plaub daim di ncauj, qhov qhib thiab kaw lub zog yog tswj ntawm Tsawg dua lossis sib npaug ntawm 38N·m (DN50) thiab Tsawg dua lossis sib npaug li 48N·m (DN65), kom tsis txhob muaj kev cuam tshuam hauv qhov qis- qhov kub thiab txias thiab lub neej ua haujlwm ntev tshaj 15 xyoo.

2 Localized Weather Resistance Design

Composite Sealing System: Txais ob-theem qauv ntawm "EPDM lub ntsiab foob + graphite- tau ntim cov foob thib ob". Lub foob tseem ceeb yog lub luag haujlwm rau kev sib khi ib txwm, thaum lub foob thib ob tau them nyiaj rau kev sib khi tshwj xeeb ntawm -35℃. Tus nqi xau tsawg dua los yog sib npaug li 0.005mL / min, thiab nws cov corrosion tsis kam rau hluav taws kub-tawg ua npuas ncauj concentrate yog 40% siab dua li ntawm EPDM ntshiab.

Anti- Txheej Txheem Txheej Txheem Txheej Txheem: Qhov saum npoo tau txais peb - txheej tiv thaiv "sandblasting derusting + npib tsib xee plating + epoxy resin txheej", ua tiav tsis muaj corrosion tom qab 12,000 teev ntawm ntsev tsuag tshuaj corrosion. Nws yog yoog tau rau cov av qis hauv UK thiab thaj chaw muaj kev lag luam hauv Australia.

3 Kev hloov kho ntse ntse

Ceev -Nruab Antifreeze Structure: A φ15mm ceev- qhib lub qhov dej yog teem rau hauv qab ntawm lub valve lub cev, nruab nrog ib tug British txheem tooj dag plug. Cov dej seem hauv lub valve tuaj yeem tso tawm tsis pub dhau 30s tom qab kaw, tiv thaiv kom khov thiab tawg hauv thaj chaw txias xws li Scottish Highlands. Lub qhov dej tau txais cov qauv kev sib khi uas muaj qhov qhib lub zog tsawg dua lossis sib npaug li 15N·m rau kev ua haujlwm kub ntxhov.

Lub M20 × 1.5 siab sensor interface yog tshwj tseg rau sab ntawm lub valve lub cev, uas tuaj yeem txuas ncaj qha rau cov hluav taws xob hauv British hluav taws xob (xws li FireClass series) los saib xyuas lub siab ua ntej lub valve hauv lub sijhawm. Lub teeb liab tsis siv neeg thaum ntxov tau tshwm sim thaum lub siab hloov pauv siab tshaj ± 0.2MPa. Lub handwheel integrates ib tug anti-slip rib tsim nrog ib tug tav siab ntawm 1.5mm, ua rau cov kev sib txhuam coefficient mus rau 0.8 thaum ua hauj lwm nrog txias- hnab looj tes pov thawj kom tsis txhob ntog nyob rau hauv qis kub.
