Ib lub valve yog ib qho cuab yeej siv los tswj cov kev taw qhia, siab, thiab ntws ntawm cov kua dej hauv cov dej hauv lub cev. Nws ua kom tau lossis tso tseg qhov ntws tawm ntawm cov xov xwm (kua, roj av, hmoov muaj hmoov) tsis pub dhau cov kav dej thiab khoom siv, thiab tuaj yeem tswj hwm lawv cov ntws.
Ib lub pob valve yog kev tswj hwm hauv cov raj dej ntws hluav taws xob, siv los hloov cov ntoo khaub lig- ntu ntawm nruab nrab ntws. Nws ua haujlwm xws li kev ntxhov siab, kev sib tsoo, throttling, kuaj xyuas, hloov pauv, lossis rho tawm kom daws tau siab. Li li qub siv rau cov txheej txheem cov roj tuaj nyob rau hauv ntau hom thiab specifications, los ntawm yooj yim globe siv cov tshuab tswj tau zoo tsis siv neeg. Valve nomavinal diameters ntawm cov twj paj nruag me me los li qub rau li qub rau cov kav dej muaj nrog diameters txog li 10 meters. Li qub yuav siv tau los tswj cov dej ntws ntawm ntau yam dej, nrog rau cov dej, roj, roj av, cov hlau ua kua, thiab kua hluav taws xob. Valves can operate at pressures ranging from 0.0013 MPa to ultra-high pressures of 1000 MPa, and at temperatures ranging from -270℃to 1430℃. Cov li qub tuaj yeem tswj tau los ntawm ntau yam kev hloov pauv, hluav taws xob, hluav taws xob, roj electromagnetic hydraulic, roj-hydraulic, spur iav, bevel iav tsav, thiab lwm yam; Lawv tuaj yeem ua raws li tau txiav txim siab ua ntej kev txiav txim siab, ntsuas kub lossis lwm hom ntawm lub cim qhia, lossis tsuas yog qhib lossis kaw tau ntawm cov cim sensor. Lub valve rau ib tug tsav lossis tsis siv neeg kho tshuab los ua kom qhib thiab kaw, yog li hloov pauv qhov loj me me los ua kom tiav nws txoj haujlwm tswj hwm.
