Now 'parallel-slide gate valve' is a global trend.
1. Lub qhov rooj vag qhov rooj vag kaw nrog zawv zawg qhov rooj es tsis txhob siv cov compression li niaj zaus, yog li tsis muaj kev nyiam, thais lossis indent ntawm qhov chaw sealing. Qhov tshwm sim ntawm qhov kev ua no tuaj yeem ua rau muaj kev nruj dua rau cov disc ntawm lub rooj zaum -ntiv nplhaib, thiab lub neej ntev dua ntawm cov discs thiab lub rooj zaum sealing nto.
2. Parallel- swb rooj vag valve muaj kev ua haujlwm tu nrog kev sib cuag ntawm cov rooj zaum thaum lub sijhawm kaw. Yog li yog tias muaj cov impurities tshwm sim los yog nyiam ntawm cov rooj zaum thiab cov discs, lawv raug tshem tawm thiab kev sib txuas yog pub dawb los ntawm cov khoom tsis zoo. Nws kuj txo cov kev ntxhov siab ntawm lub rooj zaum thiab lav lub neej ntev. Lub rooj zaum dav dav tuaj yeem txo qhov cuam tshuam ntawm kev puas tsuaj me me rau ntawm qhov chaw raws li kev sib khi tshwm sim rau tag nrho saum npoo.
3. Tsis muaj lub zog ntxiv thiab qhov kawg ntawm lub zog ntawm lub zog yuav tsum ua kom lub tog zaum tog - nruj vim tias kev sib khi yog tau los ntawm zawv zawg, tsis yog los ntawm compression. Tsis tas li ntawd, lub valve ua haujlwm nrog lub zog qis vim tias tsis xav tau lub zog siab thaum qhib lub li qub.
4. Tus actuator loj ntawm qhov sib npaug ntawm lub qhov rooj zawv zawg tuaj yeem ua tau me dua li cov kab sib txuas. Rauj lossis cuam tshuam tes- lub log feem ntau tsis tsim nyog ntawm lub valve no.
5. Lub zog torque qis ua rau muaj kev ntxhov siab tsawg thiab qaug zog ntawm qhov txiav. Qhov no ua rau lub neej ntev dua thiab muaj dej ntau dua - nruj kev ntseeg.
6. Thaum lub valve raug kaw, qhov tseeb txoj hauj lwm ntawm qia koob tsis ua lub luag haujlwm zoo. Yog li ntawd, tsis muaj teeb meem nrog qhov sib txawv ntawm thermal expansion coefficient ntawm cov ntaub ntawv. Tsis tas li ntawd, cov actuators tuaj yeem nres nrog cov keyboards dav dav.
7. Qhov ua tau jam pom nyob rau hauv lub qhov rooj vag li qub vim lub cev contraction yuav tsis tshwm sim nyob rau hauv parallel slide gate li qub.
8. Nyob rau hauv lub rooj vag qhov rooj, lub npoo yuav tsum muaj kev taw qhia ntawm nws cov slides kom nws inline thaum kaw nyob rau hauv tag nrho cov dej ntws. Cov lus qhia no feem ntau tsis yog ua los ntawm cov ntaub ntawv nyuaj, thiab nyiam hnav, thiab thaum kawg tuaj yeem ua rau jamming.
Cov teeb meem ntawm cov khoom wedge gate valves:
1. Kev ua haujlwm tsis zoo ntawm qhov qhib disc vim yog Thermal Binding
Nyob rau hauv cov kab nrib pleb, thermal binding yog tshwm sim los ntawm qhov cuam tshuam ntawm cov npoo thiab lub rooj zaum, vim temp-erature sib txawv thiab thermal expansion. Valves feem ntau yog siv nyob rau hauv siab.
2. Cov teeb meem tawg vim thermal deformation
Txij li thaum lub sealing ntawm lub valve yog tau los ntawm compression, txaus siab ntawm cov discs thiab cov rooj zaum yog tsim nyog. Lub cev yuav tsum tau tsim kom tuab thiab muaj zog kom sawv rov los.
