Mapangidwe avalve ya diaphragmndi yosiyana kwambiri ndi mavavu wamba.Ndi mtundu watsopano wa valve ndi mawonekedwe apadera a valve yotseka.Gawo lake lotsegula ndi lotseka ndi diaphragm yopangidwa ndi zofewa Mkati mwa chivundikirocho ndi gawo loyendetsa galimoto zimalekanitsidwa, ndipo tsopano zimagwiritsidwa ntchito kwambiri m'madera osiyanasiyana.Mavavu a diaphragm omwe amagwiritsidwa ntchito kawirikawiri amaphatikizapo ma valve a diaphragm okhala ndi mphira, ma valve a diaphragm okhala ndi fluorine, ma valve a diaphragm opanda mzere, ndi ma valve a pulasitiki a diaphragm.
Vavu ya diaphragm imakhala ndi diaphragm yosinthika kapena diaphragm yophatikizika m'thupi la valavu ndi chivundikiro cha valve, ndipo gawo lake lotseka ndi chipangizo cholumikizira cholumikizidwa ndi diaphragm.Mpando wa valve ukhoza kukhala mtundu wa weir kapena mtundu wowongoka.
Ubwino wa valve ya diaphragm ndikuti njira yake yogwiritsira ntchito imasiyanitsidwa ndi ndime yapakati, yomwe sikuti imangotsimikizira chiyero cha sing'anga yogwira ntchito, komanso imalepheretsa mwayi wa sing'anga mu payipi yomwe imakhudza mbali zogwirira ntchito.Kuphatikiza apo, palibe chisindikizo chosiyana chamtundu uliwonse chomwe chimafunikira pa tsinde, kupatula ngati gawo lachitetezo pakuwongolera zowulutsa zowopsa.
Mu valavu ya diaphragm, popeza sing'anga yogwira ntchito imangolumikizana ndi diaphragm ndi thupi la valve, onse omwe amatha kugwiritsa ntchito zipangizo zosiyanasiyana, kotero valavu imatha kulamulira mitundu yosiyanasiyana ya ntchito, makamaka yoyenera mankhwala owononga kapena zoimitsidwa particles.wapakati.
Kutentha kwa valavu ya diaphragm nthawi zambiri kumakhala kochepa ndi zipangizo zomwe zimagwiritsidwa ntchito pazitsulo za diaphragm ndi valavu, ndipo kutentha kwake kumakhala pafupifupi -50 mpaka 175 ° C.Valavu ya diaphragm ili ndi dongosolo losavuta ndipo imangokhala ndi zigawo zitatu zazikulu: thupi la valve, diaphragm ndi msonkhano wophimba valavu.Valavu ndiyosavuta kusokoneza ndikukonzanso mwachangu, ndipo kusinthidwa kwa diaphragm kumatha kuchitika pamalowo komanso kwakanthawi kochepa.
Zida za valve ya diaphragm:
Lining zakuthupi (code), kutentha kwa ntchito (℃), sing'anga yabwino
mphira wolimba (NR) -10 ~ 85 ℃ Hydrochloric acid, 30% sulfuric acid, 50% hydrofluoric acid, 80% phosphoric acid, alkali, mchere, zitsulo plating solution, sodium hydroxide, potaziyamu hydroxide, ndale saline solution, 10% sodium hypochlorite , klorini yotentha, ammonia, ma alcohols ambiri, ma organic acid ndi aldehydes, etc.
Mpira Wofewa (BR) -10 ~ 85 ℃ Simenti, dongo, phulusa la cinder, feteleza wa granular, madzimadzi olimba okhala ndi abrasiveness amphamvu, kuchuluka kwa ntchofu zakuda, ndi zina zambiri.
Fluorine rabara (CR) -10～85℃ Mafuta a nyama ndi masamba, zothira mafuta ndi matope owononga okhala ndi pH yamitundu yambiri.
Butyl rabara (HR) -10 ~ 120 ℃ Organic acids, alkalis ndi hydroxide compounds, salt inorganic salt and inorganic acids, elemental gas alcohols, aldehydes, ethers, ketones, etc.
Polyvinylidene fluoride propylene pulasitiki (FEP) ≤150 ℃ Hydrochloric acid, sulfuric acid, aqua regia, organic acid, oxidant amphamvu, alternating anaikira asidi, asidi alternating ndi zamchere ndi zidulo zosiyanasiyana organic kupatula zitsulo zamchere, elemental fluorine ndi zosungunulira hydrocarbon etc. .
Polyvinylidine fluoride pulasitiki (PVDF) ≤100 ℃
Polytetrafluoroethylene ndi ethylene copolymer (ETFE) ≤120 ℃
Pulasitiki yosungunuka ya polytetrafluoroethylene (PFA) ≤180 ℃
Polychlorotrifluoroethylene pulasitiki (PCTFE) ≤120 ℃
Enamel ≤100℃ Pewani kutentha kwadzidzidzi kupatula hydrofluoric acid, phosphoric acid ndi alkali wamphamvu.
Chitsulo choponyera popanda zingwe Gwiritsani ntchito kutentha molingana ndi zida za diaphragm valve Zosawononga.
Chitsulo chosapanga dzimbiri chosapanga chingwe General corrosive media.
Kusamalira Mavavu a Diaphragm
1. Musanakhazikitse valavu ya diaphragm, fufuzani mosamala ngati machitidwe a payipi akugwirizana ndi momwe valavu imagwiritsidwira ntchito, ndipo mkatikati mwa mkati ayenera kutsukidwa kuti dothi lisamangidwe kapena kuwononga zigawo zosindikizira.
2. Osajambula pamwamba pa mphira wa rabara ndi diaphragm ya rabara ndi mafuta kuti mphira asatuluke komanso kukhudza moyo wautumiki wa valve diaphragm.
3. Chiguduli chamanja kapena njira yotumizira sikuloledwa kugwiritsidwa ntchito pokweza, ndipo kugundana ndikoletsedwa.
4. Pogwiritsira ntchito valve ya diaphragm pamanja, chothandizira chothandizira sichiyenera kugwiritsidwa ntchito kuteteza kuwonongeka kwa zigawo zoyendetsa galimoto kapena kusindikiza zigawo chifukwa cha torque yambiri.
5. Mavavu a diaphragm ayenera kusungidwa m'chipinda chowuma ndi mpweya wokwanira, ndipo kupaka ndi koletsedwa.Mbali zonse ziwiri za valavu ya diaphragm ziyenera kusindikizidwa, ndipo zotsegula ndi zotseka ziyenera kukhala zotseguka pang'ono.
Konzani zolakwika zofala za ma valve a diaphragm
1. Kayendetsedwe ka gudumu la pamanja sikusinthika: ① Tsinde la valavu ndi lopindika ②Ulusi wawonongeka ①Sinthani tsinde la valavu ②Tengerani ulusi ndikuwonjezera mafuta.
2. Valavu ya chibayo sichingatseguke ndi kutseka yokha: ①Kuthamanga kwa mpweya ndikochepa kwambiri ②Mphamvu yamasika ndi yayikulu kwambiri ③Mpumi wa rabara wawonongeka ①Wonjezerani mphamvu ya mpweya ②Chepetsani mphamvu ya masika ③Sinthani chiwalo.
3. Kutayikira pakulumikizana pakati pa valavu ndi bonati: ①Bawuti yolumikizira ndi yotayirira ②Chingwe cha mphira chasweka ①Mangitsani bawuti ②Sinthani thupi la valavu.
