✧ Nqe lus piav qhia
Cov ntsiab lus tseem ceeb ntawm daim tshev valve yog forged los ntawm stainless hlau nrog kev yaig siab heev thiab cov yam ntxwv tsis zoo. Cov ntsaws ruaj ruaj siv cov vulcanization theem nrab uas ua rau qhov kawg sealing. Peb tuaj yeem muab cov khoom siv sab saum toj nkag, hauv kab flapper check li qub thiab dart check li qub. Flappers kos li qub feem ntau yog siv hauv cov kua dej lossis cov kua dej sib xyaw ua ke. Dart check li qub feem ntau yog siv rau hauv cov pa roj los yog cov kua ntshiab uas muaj cov viscosity tsawg.
Dart Check Valve yuav tsum muaj tsawg kawg nkaus kom qhib. Elastomer seals yog tus nqi qis thiab yooj yim rau kev pabcuam. Alignment insert pab txo kev sib txhuam, txhim kho concentricity thiab nce lub cev lub neej thaum muab lub foob zoo. Weep qhov yog qhov qhia txog qhov xau thiab kev nyab xeeb lub qhov.
Dart Style Check Valve yog qhov tshwj xeeb uas tsis yog rov qab (ib-txoj kev) valve tsim raws li kev ua haujlwm nyob rau hauv lub siab tsis tshua muaj siab thiab kub hauv cov chaw tsim kho roj. Dart hom Kos Valve feem ntau muaj lub cev lub cev, lub nplhaib foob, xauv txiv ntoo, lub caij nplooj ntoos hlav, lub caj pas kaw, O-rings, thiab plunger. Dart Check Valves raug suav hais tias txhim khu kev qha thaum lub sijhawm ua haujlwm ntau yam roj av, xws li cementing, acid stimulation, zoo tua ua haujlwm, hydraulic fracturing, zoo tu thiab tswj cov khoom, thiab lwm yam.
