Lub valve yog cov khoom siv tswj cov kav dej. Nws txoj haujlwm tseem ceeb yog txhawm rau txuas lossis thaiv qhov ntws ntawm cov kav dej nruab nrab, hloov qhov ntws ntawm qhov nruab nrab, hloov kev txav ntawm qhov nruab nrab, kho qhov siab thiab ntws ntawm qhov nruab nrab, thiab tiv thaiv kev ua haujlwm ntawm cov khoom siv hauv cov kav dej.
Ntau daim ntawv thov ntawm kev lag luam li qub yog tom qab Watt tsim cov tshuab hluav taws xob. Hauv ob mus rau peb lub xyoos dhau los, vim kev xav tau ntawm roj av, tshuaj lom neeg kev lag luam, chaw nres tsheb fais fab, metallurgy, nkoj, nuclear fais fab, aerospace, thiab lwm yam., cov kev xav tau siab dua tau muab tso rau hauv li qub thiab kev sib tham tau txhawb nqa. Thiab kev tsim cov khoom siv hluav taws xob siab, nws qhov ua haujlwm kub ntawm qhov kub tsis tshua muaj siab -269 ℃ mus rau qhov kub siab 1200 ℃, thiab txawm tias siab li 3430 ℃, ua haujlwm siab los ntawm ultra-vacuum 1.33x10-8Mpa (1x10-1 mmHg ) rau ultra-siab siab 1460MPa, thiab lub valve txoj kab uas hla yog los ntawm 1mm mus rau 600mm, thiab txawm mus rau 9750mm, cov ntaub ntawv valve tau tsim los ntawm cam khwb cia hlau, carbon steel rau titanium thiab titanium alloys, high-strength corrosion-resistant steel, thiab lwm yam. . Lub valve tsav hom tau tsim los ntawm phau ntawv mus rau hluav taws xob, pneumatic, hydraulic, kev tswj hwm, CNC, thiab lwm yam. Cov chaw taws teeb tswj thiab lwm yam.
Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam niaj hnub, qhov kev thov rau cov li qub tseem loj hlob tuaj, thiab cov nroj tsuag petrochemical niaj hnub xav tau ntau txhiab tus li qub, thiab kev siv cov li qub yog loj. Kev qhib thiab kaw ntau zaus, tab sis feem ntau vim yog kev tsim khoom, siv, xaiv, thiab kho tsis raug, qhov tshwm sim ntawm kev khiav, emitting, dripping, thiab leaking tshwm sim, ua rau cov nplaim taws, tawg, lom, thiab scalding, uas yuav ua rau cov khoom tsis zoo. thiab txhim kho kev siv zog. Cov xwm txheej xws li cov khoom siv corrosion, kev txhim kho cov khoom siv, kev ua qias tuaj ib puag ncig, thiab txawm tias tsim cov khoom lag luam nres tau tshwm sim tsis kawg. Yog li ntawd, txhua tus xav kom tau txais cov khoom zoo li qub. Tib lub sijhawm, lawv kuj thov kom txhim kho kev siv thiab kho qib ntawm li qub. Lub sijhawm no, nws yog rau cov neeg ua haujlwm valve, kho cov neeg ua haujlwm thiab engineering Ntxiv rau kev tsim qauv zoo, kev xaiv tsim nyog thiab kev ua haujlwm ntawm lub valve, cov kws tshaj lij tau muab cov lus thov tshiab. Lawv kuj yuav tsum tau kev tiv thaiv thiab kho nyob rau hauv lub sij hawm kom txo tau lub valve' s" khiav, leaking, dripping, thiab to" thiab ntau yam xwm txheej.
