Kushanda musimboti uye kupatsanura cheki vharafu
Cheki vharafu: cheki vharafu inozivikanwawo secheki vharafu kana cheki vharafu, basa rayo nderekudzivirira pombi yepakati kuyerera kumashure.Kusveta kwepombi yemvura kubva pavharuvhu yepasi zvakare ndeye cheki vharuvhu.Zvikamu zvekuvhura nekuvhara zvinovhurwa kana kuvharwa nekuyerera uye simba repakati kudzivirira kudzoka kwevheji yepakati inonzi check valve.Cheki vharuvhu ndeye otomatiki vharafu kirasi, cheki vharafu inonyanya kushandiswa kune imwe-nzira kuyerera kwemidhiya papombi, inongobvumira midhiya kuyerera munzira imwe, kudzivirira tsaona.Chengetedza vharafu zvinoenderana nechimiro, inogona kukamurwa kuita yekusimudza cheki vharafu, swing cheki vharafu uye butterfly cheki vharafu matatu.Simudza cheki vharafu inogona kukamurwa kuita vertical cheki vharafu uye yakachinjika cheki vharafu mbiri.Swing cheki vharafu yakakamurwa kuita imwechete disc cheki vharafu, kaviri disc cheki vharafu uye akawanda-dhisiki cheki vharafu matatu.Butterfly cheki vharafu kune yakatwasuka-kuburikidza nekutarisa vharafu, iyo pamusoro akati wandei mavharuvhu ekutarisa muchimiro chekubatanidza anogona kukamurwa kuita shinda yekubatanidza cheki vharafu, flange yekubatanidza cheki vharafu uye welding cheki vharafu matatu.

Cheka kuisirwa valve kunofanirwa kutarisisa kune zvinotevera:
Usaisa cheki mavharuvhu mumutsetse.Mavhavha makuru ekutarisa anofanirwa kutsigirwa zvakasununguka kuti avadzivirire kubva pakumanikidzwa kunoitwa nemutsara.
Paunenge uchiisa, teerera kune kutungamira kwekuyerera kwe media kunofanirwa kuenderana nekutungamira kwemuseve wemuviri wevharuvhu.
Simudza vertical flap cheki mavharuvhu anofanirwa kuiswa mune yakatwasuka pombi.
Kusimudza horizontal disc cheki mavharuvhu anofanirwa kuiswa mumapaipi akatwasuka.
Main performance parameters ye cheki valve:
Paunenge uchiisa, teerera kune kutungamira kwekuyerera kwe media kunofanirwa kuenderana nekutungamira kwemuseve wemuviri wevharuvhu.
Simudza vertical flap cheki mavharuvhu anofanirwa kuiswa mune yakatwasuka pombi.
Kusimudza horizontal disc cheki mavharuvhu anofanirwa kuiswa mumapaipi akatwasuka.
Main performance parameters ye cheki valve:
Nominal pressure kana pressure level: PN1.0-16.0mpa, ANSI Class150-900, JIS 10-20K, zita rekuti dhayamita kana dhayamita: DN15 ~ 900, NPS 1/4~36, mode yekubatanidza: flange, butt welding, thread, socket welding, etc., tembiricha inoshanda: -196℃~540℃, body material: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8(304), CF3(304L), CF8M(316), CF3M(316L), Ti.Sarudza zvinhu zvakasiyana-siyana, cheki vharafu inogona kuenderana yakakodzera mvura, chiutsi, mafuta, nitric acid, acetic acid, oxidizing medium, urea uye mamwe midhiya.
Nortech ndeimwe yeanotungamira maindasitiri ekugadzira mavharuvhu muChina ane quality certification ISO9001.
