Kodi valve ya gate ndi chiyani? Ndi chipangizo chotseka kuti chitsegule ndi kutseka kutuluka kwa madzimadzi omwe amaperekedwa ndi mapaipi (kapena mapaipi). Valve yachipata ndi valavu yolowera mbali ziwiri, chifukwa madzi amatha kuyenda mbali iliyonse. Kuyika kwa valavu yamtunduwu kumapangitsa kutsika pang'ono kwapaipi, kutsika kuposa ma valve a globe. Mavavu a zipata apanga matupi okulirapo pansi pa mainchesi awiri (API 602/BS 5352), ndi matupi oponyedwa amitundu yayikulu (API 600, API 603, API 6D).

Ubwino waukulu wa valavu yamtunduwu ndi:
Zosavuta kukonza ndi kugawa
Ndibwino kwambiri ngati valavu yotseka
Bidirectional
Mtengo wotsika
Angagwiritsidwe ntchito ndi slurries ndi viscous zakumwa
Zopezeka zazikuluzikulu
Zotetezedwa pamoto (pogwiritsidwa ntchito ndi chitsulo)
Zoyipa zake ndi:
Pang'onopang'ono kutsegula ndi kutseka nthawi
Zochepa zochepetsera mphamvu
Kukokoloka kwa mpando ndi litayamba zikhoza kuchitika
Makhalidwe olakwika akugwedezeka
Zovuta kukonza
MITUNDU YA GATE VALVE
CHIZINDIKIRO CHAPOSIDWA
Uwu ndiwo mtundu wofala kwambiri, wophimbidwa ndi API 600 (carbon and alloy steel) ndi API 603 (zitsulo zosapanga dzimbiri ndi magiredi apamwamba). Mavavu a chipata cha Cast steel amapezeka mumiyeso yopitilira mainchesi 2, mpaka mainchesi 80.
ZOCHITA ZOPHUNZITSIDWA
Mavavu opangira zitsulo amagwiritsidwa ntchito popanga mapaipi ang'onoang'ono, omwe amakhala pansi pa mainchesi 2 m'mimba mwake. Mafotokozedwe a API 602 ndi BS 5352 amaphimba mtundu uwu wa mavavu apakhomo.
API 6D FOR PIPELINES (THROUGH-CONDUIT)
Awa ndi ma valve olowera pamapaipi ndipo amapezeka mumitundu iwiri yayikulu, slab ndi chipata chokulitsa.
PRESSURE SEAL
Ma valve osindikizira pachipata cha Pressure seal amagwiritsidwa ntchito pazovuta kwambiri. Mitundu yodziwika bwino ya ma valve ogwiritsira ntchito kuthamanga kwambiri ndi wedge yosinthika ndi valavu yosindikizira ya slide. Nthawi zambiri amapezeka ndi matupi opangidwa kapena opangidwa, miyeso yoyambira 2 mpaka 24 mainchesi ndi kuthamanga kwa 600 # mpaka 4500 #, yokhala ndi socket weld kapena butt weld, malekezero kuti atsimikizire kulumikizana kolimba (komanso nsonga zopindika ndizotheka).
