1. Adhesive bonding method (adhesive type)
Muaj cov xwm txheej: Tsau cov kav dej nrog txoj kab uas hla ntawm DN15-DN200 thiab siab ≤ 1.6MPa.
Cov ntsiab lus ua haujlwm:
(a) Cov yeeb nkab qhib kev kho: PVC yeeb nkab txiav yuav tsum tiaj tus thiab tsis muaj burrs, thiab sab nrauv ntawm cov yeeb nkab yuav tsum tau polished me ntsis los txhim kho adhesion.
(b) Daim ntawv thov kua nplaum tshwj xeeb: Siv PVC tshwj xeeb nplaum kom sib npaug ntawm cov yeeb nkab phab ntsa thiab lub qhov (socket), ntxig thiab tig 45 ° kom sib npaug ntawm cov nplaum nplaum.
(c) Kev kho qhov yuav tsum tau ua: Tso cai sawv ntsug tsawg kawg 1 teev, thiab ua 1.5 npaug ntawm kev ua haujlwm siab sealing kuaj ua ntej dhau dej.
Qhov zoo: Muaj zog sealing thiab tus nqi qis
Kev txwv: Tom qab disassembly, nws yog ib qho tsim nyog yuav tsum ua kom puas cov khoom sib txuas
2. Active kev twb kev txuas (ob chav lead txuas)
Muaj cov xwm txheej: Lub sijhawm uas yuav tsum tau ua kom tsis tu ncua thiab kev saib xyuas (xws li cov ceg hauv tsev thiab cov khoom siv sib cuam tshuam).
Cov yam ntxwv zoo:
(a) Lub valve yog nruab nrog cov pob qij txha hloov tau ntawm ob qho kawg, thiab kev tshem tawm sai yog ua tiav los ntawm kev sib khi lub nplhaib nrog ceev.
(b) Thaum disassembling, tsuas yog loosen cov txiv ntoo thiab khaws cov yeeb nkab fittings kom tsis txhob muaj kev puas tsuaj rau cov kav dej.
Cov qauv kev ua haujlwm:
(a) Lub ntsej muag lub ntsej muag ntawm lub nplhaib sib koom ua ke yuav tsum tau muab ntsia rau sab nraud kom tsis txhob txav mus los thiab tawm.
(b) Qhwv cov ntaub ntawv raw cov ntaub ntawv 5-6 zaug los txhim kho lub foob thaum lub sij hawm threaded kev twb kev txuas, manually pre tighten thiab ntxiv dag zog nrog ib tug wrench.
