Tsis ntev los no, hauv Jinbin Rhiav, ib pawg ntawm 200 × 200 swb rooj vag li qub tau ntim thiab pib xa tawm. Qhov noswb rooj vag valveyog ua los ntawm carbon steel thiab yog nruab nrog phau ntawv worm log.

Phau ntawv swb rooj vag valve yog lub tshuab valve uas paub txog kev tswj hwm ntawm qhov nruab nrab los ntawm kev tuav haujlwm. Nws cov qauv tseem ceeb muaj lub cev valve, rooj vag phaj, tes log thiab kis tau tus mob. Lub cev valve feem ntau yog ua los ntawm cov ntaub ntawv hnav-resistant xws li cam khwb cia hlau, carbon steel los yog stainless hlau. Qhov saum npoo ntawm lub rooj vag phaj yog ua tiav los yog inlaid nrog hnav-resistant liners, uas tuaj yeem hloov mus rau qhov chaw xa khoom ntawm cov xov xwm sib txawv. Piv nrog rau cov hluav taws xob los yog pneumatic rooj vag li qub, cov khoom siv phau ntawv muaj cov yam ntxwv ntawm cov qauv compact, yooj yim installation thiab tsis tshua muaj nqi txij nkawm, thiab tshwj xeeb tshaj yog haum rau cov kav dej me me thiab nruab nrab lossis cov xwm txheej uas tsis tshua muaj kev xav tau rau automation.

Hais txog kev ua haujlwm zoo, cov txiaj ntsig tseem ceeb ntawm kev tuav cov rooj vag swb tau tshwm sim hauv peb qhov ntev: Ua ntej, lawv muaj kev sib khi zoo heev. Kev sib cuag ntawm lub rooj vag thiab lub valve lub cev siv cov roj hmab sealing los yog hlau tawv sealing tsim, uas tuaj yeem tiv thaiv kom tsis txhob muaj plua plav, cov ntaub ntawv granular thiab cov kua dej corrosive, thiab qhov kev sib khi zoo li qub tuaj yeem ncav cuag 0.6MPa. Thib ob, nws muaj peev xwm los kho cov nqi ntws. Los ntawm kev tswj qhov siab ntawm lub rooj vag phaj nqa thiab txo qis, qhov nruab nrab ntws tus nqi tuaj yeem tswj tau nyob rau hauv qhov qhib ntawm 10% mus rau 90%, ua tau raws li qhov yuav tsum tau ua rau kev tswj cov khoom siv ceev hauv kev tsim khoom. Thirdly, kev ruaj ntseg kaw muaj nuj nqi yog txhim khu kev qha. Thaum kaw tag nrho, nws tuaj yeem tiv taus kev ua haujlwm siab ntawm cov kav dej, ua kom muaj kev nyab xeeb ntawm cov khoom siv tu lossis kev ua txhaum cai thiab tiv thaiv kev tsim khoom raug mob los ntawm qhov nruab nrab rov qab.

Hauv kev siv tswv yim, kev xaiv ntawm phau ntawv swb rooj vag li qub yuav tsum tau txiav txim siab raws li qhov tsis muaj xws li cov yam ntxwv ntawm qhov nruab nrab (kub, qhov loj me, corrosiveness), txoj kab uas hla (DN50-DN1000), thiab kev ua haujlwm siab. Piv txwv li, thaum tuav cov ntaub ntawv uas muaj viscosity, yuav tsum xaiv lub rooj vag loj loj los tiv thaiv cov khoom adhesion thiab clogging. Rau kev thauj mus los ntawm cov khoom noj khoom haus qib, stainless hlau yuav tsum tau siv thiab iav-polished kom tau raws li cov qauv kev nyiam huv. Hauv kev siv txhua hnub, tsis tu ncua siv roj rau lub tshuab kis tau tus mob thiab ntxuav cov khib nyiab los ntawm qhov chaw ntawm lub rooj vag phaj tuaj yeem ua kom nws lub neej ua haujlwm tau zoo thiab ua kom muaj kev ruaj ntseg mus ntev.

Jinbin li qub tau raug tsim ntau yam khoom zoo li qub rau 20 xyoo (Slide Gate Valve Manufacturers). Yog tias koj muaj qee yam kev xav tau, thov hu rau peb hauv qab no thiab koj yuav tau txais lus teb tsis pub dhau 24 teev! (Slide Gate Valve Nqe)
