3. High Frictional Resistance: Globe li qub '' tsim ua rau muaj kev sib txhuam ntau dua, yog li cov nqi hluav taws xob nce ntxiv thiab txo kev ua haujlwm.
** Lub Pob Valve yog dab tsi?
Lub pob valve, ntawm qhov tod tes, yog ib hom valve uas siv lub pob hlau perforated los tswj cov dej ntws. Lub pob rotates nyob rau hauv lub valve lub cev thiab tswj cov kua ntws los ntawm aligning lub pob qhov nrog lub valve lub cev qhov inlet thiab qhov hluav taws xob ports. Lub pob valve tsim tso cai rau kev qhib thiab kaw ntawm lub valve sai thiab yooj yim, ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum tau ua haujlwm ntau zaus. Pob li qub tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab teeb tsa, suav nrog tag nrho qhov chaw nres nkoj, txo qhov chaw nres nkoj, thiab kab noj hniav tsim qauv.
Ib qho tshwj xeeb ntawm cov pob li qub yog lawv lub peev xwm bidirectional ntws. Qhov no txhais tau hais tias cov kua dej tuaj yeem ntws los ntawm lub valve hauv ob qho kev taw qhia, ua rau lawv haum rau cov ntawv thov uas xav tau kev tiv thaiv rov qab. Pob li qub kuj tseem muaj peev xwm sib khi zoo dua, tiv thaiv cov kua dej thaum kaw. Lub pob valve tsim kuj ua kom ntseeg tau tias lawv tswj cov nqi ntws loj, ua rau lawv zoo tagnrho rau kev siv siab txaus.
** Qhov zoo ntawm Pob Valves
1. Kev khiav hauj lwm ceev thiab yooj yim: Pob li qub muab ceev thiab yooj yim qhib thiab kaw, ua rau lawv haum rau cov ntawv thov uas yuav tsum tau ua haujlwm tsis tu ncua.
2. Loj Flow Rate Capability: Pob li qub tuaj yeem tswj cov nqi ntws loj, ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau cov nqi ntws siab.
3. Superior Sealing Capability: Pob li qub muaj peev xwm sealing zoo dua, tiv thaiv cov kua dej tawm thaum kaw.
4. Bidirectional Flow Capability: Pob li qub yog bidirectional thiab tuaj yeem tswj cov dej ntws mus rau ob qho kev taw qhia, ua rau lawv tsim nyog rau cov ntawv thov uas yuav tsum muaj kev tiv thaiv kev thim rov qab.
** Qhov tsis zoo ntawm Pob Valve
1. Muaj peev xwm Throttling txwv: Pob li qub muab lub peev xwm txo qis, ua rau lawv tsis haum rau cov ntawv thov uas yuav tsum tau tswj xyuas kom meej.
2. Tsawg Precise Shut-Off Capability: Pob li qub muab lub peev xwm kaw tsawg dua thaum piv rau lub ntiaj teb li qub, uas tuaj yeem ua rau cov kua dej tawm hauv lub cev.
3. Kev xav tau ntau dua torque: pob li qub xav tau lub zog siab dua los ua haujlwm, txhais tau tias lawv yuav tsis haum rau cov ntawv thov uas yuav tsum tau ua haujlwm qis.
