Kev kub siab viav vias kos valve, viav vias kos valve tsim thiab tsim raws li ASME B16.34, kuaj thiab tshuaj xyuas rau API598, API6D.

Qhov kev qhib ntawd yuav tsum tau meej meej kom txhua yam dhau mus.Lub disc txuas nrog lub pob khawm, yog li lub disc tuaj yeem qhib lossis kaw thaum cov kua ntaus lub disk.Nws zoo li lub qhov rooj ncig.Kev taw qhia ntawm qhov ntws yog qhov tseem ceeb tshaj plaws thaum siv cov li qub no.

Thaum cov kua tau taug kev mus rau qhov xav tau, qhov siab ntawm qhov ntws thawb lub qhov rooj qhib, tso cai rau cov kua hla dhau.Thaum cov kua txav mus rau qhov tsis ncaj ncees lawm, qhov rov qab tshwm sim.Lub zog ntawm cov kua rov qab los ntawm lub valve thawb lub disc tawm tsam nws lub rooj, kaw lub valve.Thaum txhim kho lub viav vias kos valve, nws yog ib qho tseem ceeb uas nws qhib thaum cov kua tau dhau los ntawm qhov xav tau.Yog tias koj nruab ib qho ntawm cov li qub no thiab tsis muaj dej nkag mus, ces nws yog txoj hauv kev tsis ncaj ncees lawm thiab yuav tsum tau rov ua dua.Yog tias koj lub viav vias kos valve muaj qhov tseeb tsim qauv, nws tuaj yeem yooj yim tshem tawm ntawm cov kav dej.Cov valve no muaj nyob rau hauv ntau hom sib txawv.

Raws li tau hais ua ntej, lub viav vias kos valve yog rau thaum koj xav tau cov dej taug kev hauv ib qho kev taw qhia xwb.Lwm cov ntsiab lus tseem ceeb ntawm cov li qub no yog tias lawv yuav tsum tsis muaj lub zog sab nraud, uas ua rau lawv zoo tagnrho rau ntau yam kev siv.Lawv kuj cia cov kua dej hla dhau yam tsis tau ua kom cov dej ntws qeeb ntau thaum qhib tag nrho.Lub viav vias kos li qub feem ntau yog ntsia ua ke nrog lub rooj vag li qub vim tias lawv muab cov dej ntws dawb.Lawv raug pom zoo rau cov kab uas tsis tshua muaj kev khiav dej num thiab yuav tsum tsis txhob siv rau ntawm cov kab uas muaj lub suab nrov thaum lub flapping tsis tu ncua los yog pounding yuav puas tsuaj rau lub rooj zaum.
