Yuav ua li cas pob valve haujlwm: kawm txog cov txheej txheem thiab kev ua lag luam ntawm cov li qub

Pob li qub yog qhov tseem ceeb Cheebtsam tseem ceeb ntawm cov ntawv thov kev lag luam, kom ntseeg tau qhov ntws ntawm cov kua thiab roj av. Raws li cov khoom lag luam hauv lub valve kev lag luam, pob li qub yog tsim los ntawm ntau cov neeg muab khoom, nrog rau pob kws tsim khoom thiab cov chaw tshwj xeeb hauv Suav teb. Kab lus no yuav tshawb nrhiav li cas pob li cas muaj, thiab cov ntsiab lus uas cuam tshuam rau cov thawv hlau thiab stainless hlau pob li qub.

Dab tsi yog pob valve

Ib lub pob valve yog ib lub quarter-tig valve uas siv hollow, perforated, tig pob los tswj kev ntws ntawm cov kua dej. Thaum lub pob lub pob yog mus raws li cov kua dej, lub valve qhib, cia cov kua kom dhau. Hloov siab, thaum lub pob tau sib hloov 90 degrees, cov ntws yog thaiv thiab lub pob hluav taws xob kaw. Qhov kev siv tshuab yooj yim no ua tau lub pob uas muaj nyob hauv ntau cov ntawv thov, los ntawm cov kav dej muaj ntau rau cov txheej txheem loj.

Li cas pob valve haujlwm

Kev ua haujlwm ntawm pob valve yog yooj yim. Nws muaj ntau qhov tseem ceeb:

1. Lub cev lub cev: Qhov tseem ceeb ntawm lub valve uas yog lub pob thiab lwm yam sab hauv.
2. Phab Valve: Ib lub voj voos kheej kheej nrog lub qhov nyob hauv nruab nrab, siv los tswj cov dej ntws.
3. Rev paj: Tus pas uas txuas lub pob thiab kov lossis ua yeeb yam, cia pob kom tig.
4. Lub Rooj Zaum Valve: Ib lub cim uas haum kom nruj nreem tawm ntawm pob kom tiv thaiv kom tsis txhob to feakage thaum lub valve raug kaw.
5. Kov lossis actuator: Sab nraud tshuab sab nraud siv los tig lub pob thiab qhib lossis kaw lub pob valve.

Ua Haujlwm Me Me

Thaum kov tau muab, lub qia tig hauv lub pob hauv lub cev. Yog tias lub qhov hauv pob yog dlhos nrog cov inlet thiab qhov hluav taws xob, kua dej tuaj yeem ntws dawb. Thaum kov tau muab xa mus rau qhov chaw kaw, lub pob rotates thiab cov khoom ntim ntawm pob thaiv ntws txoj kev, zoo kaw cov kua.

Qhov Zoo Ntawm Pob Valve
