Feem ntau ntawm peb cov khaub ncaws zoo nkauj zoo nkauj hlaws ntawm lub tes tsho
Cov khoom tshwj xeeb li qub xa mus rau li qub ua los ntawm cov khoom tshwj xeeb kom ua tau raws li cov yam ntxwv ntawm qhov kub thiab txias, tiv thaiv corrosion, hnav tsis kam, thiab lwm yam kev ua haujlwm. Vim lub luag haujlwm tseem ceeb ua los ntawm cov li qub hauv kev lag luam, kev xaiv cov khoom siv valve ncaj qha cuam tshuam rau lub neej kev pabcuam thiab kev ua haujlwm ntawm cov li qub. Muaj ntau hom khoom tshwj xeeb li qub, cais los ntawm cov khoom siv ntawm lub cev valve:
(1) Cov khoom siv tsis yog xim hlau li qub xws li ceramic li qub, fiberglass li qub thiab yas li qub.
(2) Cov khoom siv hlau xws li tooj liab alloy li qub, aluminium alloy li qub, txhuas alloy li qub, Monel alloy li qub, qis alloy steel li qub, thiab siab alloy steel li qub.
(3) Hlau lub cev kab li qub xws li cov hlau lead kab li qub, yas kab li qub, thiab cov hlua khi li qub.
Cov valve tshwj xeeb uas tsim los ntawm BOLON yog ua los ntawm cov khoom siv hlau. Muab faib los ntawm lub hom phiaj thiab kev ua haujlwm raws li hauv qab no:
(1) Siv los txiav tawm lossis txuas xov xwm ntws. Xws li lub rooj vag li qub, lub ntiaj teb li qub, diaphragm li qub, pob li qub, ntsaws li qub, npauj npaim li qub, plunger li qub, pob ntsaws li qub, koob ntsuas li qub, thiab lwm yam.
(2) Siv los tswj tus nqi ntws, siab, thiab lwm yam ntawm qhov nruab nrab. Nrog rau kev tswj cov li qub, lub tshuab nqus tsev valve, lub siab txo qis, thiab lwm yam.
(3) Siv los tiv thaiv kev tshaj tawm kom rov qab. Xws li kos li qub ntawm ntau yam qauv.
(4) Siv rau kev sib cais, faib, lossis sib xyaw cov xov xwm. Nrog rau kev faib tawm li qub thiab cov dej ntws tawm ntawm ntau yam qauv.
Yuav xaiv cov khoom siv valve li cas
Kev xaiv cov khoom siv valve tsim nyog yuav tsum xav txog ntau yam xws li kev ua haujlwm ib puag ncig, kev ua haujlwm nruab nrab, kev ua haujlwm kub, thiab siab. Feem ntau hais lus, thaum xaiv cov khoom tshwj xeeb valve, cov ntsiab lus hauv qab no yuav tsum raug sau tseg:
1. Kev xaiv raws li kev ua haujlwm nruab nrab: Cov khoom siv valve sib txawv tuaj yeem tiv taus cov xov xwm sib txawv, thiab cov ntaub ntawv sib xws yuav tsum raug xaiv raws li cov khoom ntawm cov xov xwm.
2. Kev xaiv raws li kev ua haujlwm kub thiab siab: Nws yog ib qho tsim nyog yuav tsum xaiv cov khoom siv valve raws li cov yam ntxwv xws li kev ua haujlwm kub thiab siab kom ntseeg tau tias lub valve tuaj yeem ua haujlwm tau zoo.
3. Kev txiav txim siab txog kev lag luam: Cov khoom tshwj xeeb valve sib txawv muaj cov nqi sib txawv, thiab nws yuav tsum tau ua tib zoo xav txog kev lag luam los xaiv cov khoom tsim nyog.
Kev ceev faj rau kev siv cov khoom siv tshwj xeeb valve
1. Thaum siv, nws yog ib qho tsim nyog kom tsis txhob muaj kev cuam tshuam thiab kev co, thiab kom tsis txhob muaj kev sib tsoo ntawm cov khoom siv;
2. Cov txheej txheem kev khiav hauj lwm yuav tsum tau ua raws li kev saib xyuas thiab tu kom tsis txhob siv cov khoom siv corrosive xws li acids thiab alkalis;
3. Ua ntej siv cov khoom siv tshwj xeeb valve, kev tshuaj xyuas thiab kev kuaj xyuas zoo yuav tsum tau ua kom ntseeg tau tias cov ntaub ntawv ua tau raws li qhov yuav tsum tau ua;
4. Thaum siv, nws yog ib qho tsim nyog yuav tsum tsis tu ncua xyuas cov xwm txheej thiab kev ua haujlwm ntawm cov khoom siv tshwj xeeb valve.
Valve cov ntaub ntawv tshwj xeeb yog qhov tseem ceeb rau kev tswj hwm lub valve ua haujlwm ib txwm muaj, thiab xaiv cov khoom siv tshwj xeeb valve tsim nyog yog qhov tseem ceeb rau kev txhim kho valve kev pab cuam lub neej thiab kev nyab xeeb. Thaum siv cov ntaub ntawv tshwj xeeb valve, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo saib xyuas kev nyab xeeb thiab kev saib xyuas tsim nyog.
BOLON alloy cov ntaub ntawv suav nrog duplex stainless hlau, super duplex stainless hlau, alloy 20, Monel alloy, Hastelloy alloy, chromium cobalt alloy, ntshiab titanium, titanium alloy, 904L, zirconium, uranium, 254 SMO, 6Moly (6Mo), nickel, thiab lwm yam. . email.
