Khoom nta
Raws li qhov xav tau ntawm qhov xwm txheej tiag tiag, cov qauv hauv qab yog tsim los ua hom hauv qab tiaj tus, thiab lub cev lub cev yog V-hom. Nws kuj muab ob hom kev ua haujlwm ntawm kev nqa thiab txo qis. Lub puab kab noj hniav ntawm lub valve lub cev yog nruab nrog anti yaig thiab anti-corrosion sealing nplhaib, uas muaj peev xwm tiv thaiv lub valve lub cev los ntawm nruab nrab erosion thiab corrosion thaum lub sij hawm qhib. Lub nplhaib sealing tshwj xeeb yog kho kom lub ntsej muag hardness ncav cuag hrc56-62, uas muaj kev ua haujlwm siab hnav tsis kam thiab tiv thaiv corrosion. Lub sealing nto ntawm lub valve disc yog overlaid nrog cemented carbide thaum tsim nyog, thiab lub sealing khub txais kab foob los xyuas kom meej qhov kev cia siab ntawm lub foob thiab tiv thaiv caws pliav. Nyob rau tib lub sijhawm, tus tsim ntawm luv luv stroke disc yog saws. Ntau hom kev ua haujlwm, xws li phau ntawv, pneumatic (lub caij nplooj ntoos hlav rov qab, ob chav ua yeeb yam, nrog thiab tsis muaj tes), hluav taws xob, hydraulic, iav, thiab lwm yam.
