IB TUG OVERCENTRE VALVES FIXING NTAWM SAWV

 

Cov li qub no yog siv los tswj cov actuator txav thiab thaiv hauv ib qho kev taw qhia. Txhawm rau kom muaj qhovntsej thiaj tsis mob ntawm kev tswj hwm thiab zam lub nra hnyav ntawm lub valve yuav tiv thaiv kev tawm tsam ntawm tus actuator. Kev sib txuas tshwj xeeb los ntawm cov ntsia hlau, nkag nrog lub valve, ua kom ncaj qha mounting ntawm lub valve mus rau lub actuator.


Paub meej

Qhov ib leeg overcenter li qub ntawm cov series yog tsim los xyuas kom meej qhov kev ruaj ntseg nyob rau hauv txoj hauj lwm ntawm hydraulic actuator nrog tshem tawm load, thiab tswj nws lub zog nyob rau hauv tsuas yog ib qho kev taw qhia (feem ntau yog lub qhovntsej thiaj tsis mob theem), tawm hauv lub opposite sab powered los ntawm dawb ntws; Ua tsaug rau lub vaj tse rau lub banjo bolt ntawm lub valve lub cev, lawv tuaj yeem ntsia tau ncaj qha rau ntawm lub tog raj kheej lub taub hau, ua kom yooj yim rau hauv Circuit Court nyob rau hauv kev pom zoo ntawm lub sij hawm sib dhos, thiab optimizing kev ua tau zoo ua tsaug rau qhov ntim ntawm hysteresis phenomenon.

Lub fitting bolt yuav tsum tau ntsia rau ntawm lub tog raj kheej rov kab. Los ntawm kev pub cov kab rov qab ntawm cov khoom thauj, cov kab tsav tsheb tswj kev qhib ib feem ntawm qhovntsej thiaj tsis mob channel tso cai rau kev tswj hwm ntawm tus actuator txav thiab zam qhov tshwm sim ntawm cavitation ua tsaug rau qhov kev txiav txim ntawm qhov sib txawv ntawm lub zog gravitational. Lub qhov calibrated dampens lub teeb liab tsav kom lub valve qhib thiab kaw proportionally, tsis txhob load oscillations. Ib leeg overcenter valve kuj ua haujlwm raws li lub valve antishock nyob rau hauv lub xub ntiag ntawm siab peaks tshwm sim los ntawm kev cuam tshuam los yog ntau loads. Txhawm rau ua qhov no, txoj kab rov qab ntawm tus xa khoom yuav tsum tau txuas nrog lub qhov dej ntws. Qhov no yog ib qho kev them nyiaj ib nrab ntawm lub valve: qhov seem seem ntawm cov kab rov qab tsis cuam tshuam rau qhov chaw ntawm lub valve thaum lawv nce tus nqi tsav tsheb.

Yog li ntawd, kev siv hom valve no muaj peev xwm ua tau nyob rau hauv cov tshuab nrog DCV nrog lub kaw qhov chaw spool. Hydraulic leakproof yog ib qho tseem ceeb feature rau lub overcenter li qub. Txhawm rau kom ntseeg tau tias qhov kev ua tau zoo tshaj plaws, Oleoweb tsim cov khoom siv sab hauv ntawm nws cov li qub hauv cov hlau muaj zog, tawv thiab sib tsoo, thiab, thaum lub sijhawm tsim khoom, ua tib zoo xyuas qhov ntev thiab geometric kam rau ua ntawm cov khoom sib khi, nrog rau lub foob nws tus kheej. lub valve sib dhos.  yog qhov chaw-hauv-lub cev li qub: tag nrho cov khoom siv nyob rau hauv lub hydraulic manifold, ib qho kev daws teeb meem uas tso cai rau kev tswj cov dej ntws siab thaum txwv qhov ntev tag nrho. Lub manifold yog ua los ntawm cov hlau rau kev ua haujlwm siab txog li 350 bar (5075) thiab hnav tsis kam; nws muaj kev tiv thaiv los ntawm corrosion los ntawm zinc plating kev kho mob thiab nws yog machined ntawm rau lub ntsej muag rau ib tug ntau zoo ua hauj lwm ntawm qhov chaw kho mob.

Rau cov ntawv thov raug tshwj xeeb aggressive corrosive agents (xws li marine applications) Zinc-Nickel kev kho mob muaj nyob rau ntawm kev thov.  valves muaj nyob rau hauv loj BSPP 3/8 "rau kev pom zoo ua hauj lwm txaus tus nqi mus txog 40 lpm (10,6 gpm). Sib txawv calibration teb thiab pilot ratios. Rau kev pom zoo, nws yog pom zoo kom teem lub overcenter li qub rau tus nqi 30%. siab tshaj qhov ua haujlwm siab tshaj plaws.
