Vavu yodulidwa imatchedwanso valavu yodulidwa. Ndi valavu yomwe imagwiritsidwa ntchito kwambiri. Chifukwa chake imatchuka ndichakuti kukangana pakati pa malo otsekera panthawi yotsegulira ndi kutseka ndi kochepa, ndi kolimba, kutalika kwa kutsegula si kwakukulu, kupanga ndikosavuta, ndipo kukonza ndikosavuta. , Sikuti kokha koyenera kuthamanga kwapakati ndi kotsika, komanso koyenera kuthamanga kwambiri.
Mfundo yotsekera ya valavu yozungulira ndi kudalira mphamvu ya tsinde la valavu kuti pamwamba pa diski ndi pamwamba pa mpando wa valavu zigwirizane bwino kuti cholumikiziracho chisayende bwino.
Vavu yotseka imalola kuti cholumikiziracho chiziyenda mbali imodzi yokha ndipo chimayenda mbali imodzi ikayikidwa. Kutalika kwa kapangidwe ka valavu yotseka ndi yayitali kuposa ya valavu ya chipata, ndipo kukana kwamadzimadzi ndi kwakukulu, ndipo kudalirika kotseka sikolimba panthawi yogwira ntchito kwa nthawi yayitali.
Pali mitundu itatu ya ma valve a globe: ma valve a globe olunjika, ma valve a globe a right-angle ndi ma valve a globe oblique olunjika.
Ubwino woonekeratu ndi wakuti panthawi yotsegula ndi kutseka, kukangana pakati pa diski ndi pamwamba pa chitseko cha thupi la valavu kumakhala kochepa kuposa kwa valavu ya chipata, kotero sichingawonongeke. Kutalika kwa chitseko nthawi zambiri kumakhala 1/4 yokha ya m'mimba mwake wa malo opachikira mpando wa valavu, kotero kumakhala kochepa kwambiri kuposa valavu ya chipata. Nthawi zambiri pamakhala pamwamba pa chitseko chimodzi chokha pa thupi la valavu ndi chivundikiro cha valavu, kotero njira yopangira ndi yabwino komanso yosavuta kusamalira.
Kupanikizika kodziwika kapena kuchuluka kwa kupanikizika kwa valavu yoyimitsa: PN1.0-16.0MPa, ANSI CLASS150-900, JIS 10-20K, m'mimba mwake kapena caliber yodziwika: DN10~500, NPS 1/2~36″, njira yolumikizira valavu yoyimitsa: flange, Butt welding, ulusi, ndi zina zotero, kutentha koyenera: -196℃~700℃, stop valve drive mode: manual, bevel gear drive, pneumatic, electric, hydraulic, gas-liquid linkage, electro-hydraulic linkage, valve body material: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti. Zipangizo zosiyanasiyana zimagwiritsidwa ntchito pa valavu yoyimitsa, yomwe ingagwiritsidwe ntchito pamadzi, nthunzi, mafuta, nitric acid, acetic acid, ndi oxidizing media. , Urea ndi zomera zina.
Nortech ndi m'modzi mwa opanga ma valve otsogola ku China omwe ali ndi satifiketi ya ISO9001 yapamwamba.
Zinthu zazikulu:Valavu ya Gulugufe,Valavu ya Mpira,Valavu ya Chipata,Valavu Yowunikira,Globe Vavlve,Zipangizo za Y,Chotsukira Magetsi,Zipangizo zoyezera mpweya (Pneumatic Acurators).
