3, pob valve: yog hloov zuj zus los ntawm lub ntsaws valve, nws qhov qhib thiab kaw qhov chaw yog lub pob, siv lub pob nyob ib ncig ntawm lub qia axis tig 90 ° kom paub lub hom phiaj ntawm kev qhib thiab kaw.Pob valve feem ntau yog siv los txiav tawm, faib thiab hloov cov kev taw qhia ntawm nruab nrab ntws hauv cov kav dej.Lub pob valve nrog v-shaped qhib kuj muaj kev khiav dej num zoo.
Qhov zoo:
(1) Tsis tshua muaj dej tsis kam (tiag tiag 0);
② Vim tias nws yuav tsis raug daig ntawm kev ua haujlwm (thaum tsis muaj roj nplua nyeem), nws tuaj yeem siv tau rau cov xov xwm corrosive thiab cov kua dej kub npau npau tsawg;
Nyob rau hauv ntau yam ntawm siab thiab kub, tuaj yeem ua tiav sealing;
④ Nws tuaj yeem paub qhov qhib thiab kaw nrawm, thiab lub sijhawm qhib thiab kaw ntawm qee cov qauv tsuas yog 0.05-0.1s kom ntseeg tau tias nws tuaj yeem siv rau hauv automation system ntawm lub txaj kuaj.ceev qhib thiab kaw ntawm lub valve, kev ua haujlwm tsis muaj kev cuam tshuam;
(5) Lub puab kheej kheej kaw qhov chaw tuaj yeem muab tso rau ntawm qhov chaw ciam teb;
⑥ Ua haujlwm nruab nrab ntawm ob sab ntawm lub foob yog txhim khu kev qha;
⑦ Thaum qhib tag nrho thiab kaw tag nrho, lub sealing nto ntawm lub pob thiab lub rooj zaum raug cais tawm ntawm qhov nruab nrab, yog li qhov nruab nrab los ntawm lub valve ntawm kev kub ceev yuav tsis ua rau yaig ntawm lub sealing nto;
⑧ compact qauv, lub teeb yuag, nws tuaj yeem suav hais tias yog qhov tsim nyog valve qauv rau qhov nruab nrab qhov kub thiab txias;
⑨ Symmetrical valve lub cev, tshwj xeeb tshaj yog welded valve lub cev qauv, tuaj yeem dais qhov kev ntxhov siab los ntawm cov kav dej zoo;
⑩ Cov khoom kaw tuaj yeem tiv taus qhov sib txawv siab thaum kaw.(11) Lub pob valve vuam lub cev, tuaj yeem muab faus ncaj qha rau hauv av, kom lub puab qhov ntawm lub valve tsis eroded, siab kev pab cuam lub neej txog li 30 xyoo, yog lub zoo tagnrho valve rau roj thiab natural gas pipelines.
Qhov tsis zoo:
(1) Vim hais tias lub ntsiab valve lub rooj sealing nplhaib khoom yog ptfe, nws yog inert rau yuav luag tag nrho cov tshuaj, thiab muaj cov yam ntxwv ntawm kev sib txhuam me me coefficient, ruaj khov kev ua tau zoo, tsis yooj yim rau kev laus, ntau yam kub thiab zoo sealing kev ua tau zoo.Tab sis lub cev yam ntxwv ntawm PTFE, nrog rau siab coefficient ntawm expansion, rhiab heev rau txias txaus thiab tsis zoo thermal conductivity, yuav tsum tau lub rooj zaum foob tsim nyob ib ncig ntawm cov yam ntxwv.Yog li ntawd, thaum cov khoom sealing hardens, qhov kev ntseeg ntawm lub foob raug puas lawm.Ntxiv mus, qhov kub tsis kam ntawm PTFE yog tsawg thiab tsuas yog siv tau nyob rau hauv cov xwm txheej ntawm tsawg dua 180 ℃.Tshaj qhov ntsuas kub no, cov khoom sib khi yuav muaj hnub nyoog.Nyob rau hauv cov ntaub ntawv ntawm kev siv mus sij hawm ntev, nws yog feem ntau tsuas yog tsis siv ntawm 120 ℃.
② Nws txoj kev tswj hwm kev ua tau zoo dua li lub ntiaj teb valve, tshwj xeeb tshaj yog pneumatic valve (los yog hluav taws xob valve).

Nortech yog ib qho ntawm cov ua lag luam valve manufacturers hauv Suav teb nrog cov ntawv pov thawj zoo ISO9001.
