Chaniis AChipata cha Chipata?
Gwero:Chithunzi cha TWS
A valve pachipatandi mtundu wa valavu yodzipatula yomwe imagwiritsidwa ntchito poyang'anira kutuluka kwa madzi m'dongosolo la mafakitale. Asluceamatanthauza ngalande yochita kupanga yothandizidwa ndi chipata chowongolera kuyenda kwamadzi. Mavavu a sluice kapenama valve pachipata cha mafakitaleamagwiritsidwa ntchito makamaka pazolinga zamakampani. Makina ake osavuta komanso osavuta amawapangitsa kukhala amodzi omwe amagwiritsidwa ntchito kwambirimavavum'mafakitale osiyanasiyana. Vavu imagwira ntchito mwa kungosuntha kapena kukweza chotchinga panjira yamadzi oyenda.
Amagwiritsidwa ntchito motsatira chitoliro munjira imodzi kapena iwiri. Ikatsegulidwa kwathunthu, imalephera kukana madzi oyenda, chomwe ndi chimodzi mwa zifukwa zazikulu zomwe imawonedwa kuti ndi yothandiza kwambiri. Maonekedwe a chipatacho mwina amakhala ofanana, koma nthawi zambiri, amasungidwa ngati mphero. Wedgema valve pachipatathandizani kupanga chosindikizira chabwinoko chikatsekedwa pamene chimagwiritsa ntchito kukakamiza pamwamba pa kusindikiza ndikupereka ntchito yabwino yosindikiza.
A valve pachipataimagwira ntchito pozungulira pamanja pa gudumu lamanja, kapena imagwiritsa ntchito cholumikizira chamagetsi kapena pneumatic.Kuzungulira kwa gudumu kangapo kumayendetsa chipata mmwamba ndi pansi, chomwe chimayang'anira kutuluka kwa madzi kapena mpweya mkati mwa valve. Kutsegula chipata kumapereka kutsekereza pang'ono kwa kuyenda koma kusunga theka lachipata kungayambitse kuwonongeka monga madzi othamanga kapena gasi angapangitse kuchuluka kwa mphamvu pa mbale. M'malo mwama valve pachipata, mavavu a globe angagwiritsidwe ntchito kuwongolera kuyenda.
Ntchito
Ngakhale avalve pachipatakapena valavu ya sluice ndiyosavuta kugwiritsa ntchito, imakhala ndi zigawo zambiri zomwe zimagwirizanitsidwa kuti zizigwira ntchito bwino. Mtundu uwu wavalavuzimakhala ndi thupi, chipata, mpando, bonati, ndipo nthawi zina, actuator amene automates kuyenda.Ma valve a zipataakhoza kupangidwa pogwiritsa ntchito zipangizo zosiyanasiyana; komabe, chitsulo chosapanga dzimbiri ndi chomwe chimakondedwa kwambiri popeza zinthuzo zimalimbana kwambiri ndi kusintha kwa kutentha kapena kupanikizika. Magawo osiyanasiyana a valve pachipata afotokozedwa mwatsatanetsatane pansipa.
Chipata
Zopezeka muzojambula zosiyanasiyana, chipata ndi gawo lalikulu la valve yachipata. Mbali yaikulu ya mapangidwe ake ndi kusindikiza kwake kwa ntchito zinazake. Avalve pachipataikhoza kuikidwa ngati valve yofanana kapena yofanana ndi mphero kutengera mtundu wa chipata. Zoyambazo zitha kugawidwanso kukhala zipata za slab, zipata zofananira, ndi zipata zokulirakulira.
Mipando
A valve pachipataili ndi mipando iwiri yomwe imatsimikizira kusindikizidwa pamodzi ndi chipata. Mipando iyi ikhoza kuphatikizidwa mkati mwa thupi la valve, kapena ikhoza kukhalapo ngati mphete ya mpando. Yotsirizirayo imakutidwa kapena kukanikizidwa pamalo ake ndikusindikizidwa ndikumangirira ku thupi la valve. M'malo omwe valavu imakhala ndi kutentha kwakukulu, mphete zapampando zimakondedwa, chifukwa zimalola kuti pakhale kusiyana kwakukulu pakupanga.
Tsinde
Gate mu avalve pachipataimatsitsidwa kapena kukwezedwa ikazungulira pa ulusi. Izi zitha kuchitika kudzera pa gudumu lamanja kapena actuator. Woyendetsedwavalve pachipataikhoza kuyendetsedwa patali. Kutengera mtundu wa sitepe, ndivalve pachipataakhoza kugawidwa m'magulu okwera tsinde ndi osakwera. Yoyamba imayikidwa pachipata, pamene yotsirizirayo imayikidwa pa actuator ndipo imalowetsedwa pachipata.
Maboneti
Maboneti ndi zigawo za valve zomwe zimatsimikizira kusindikizidwa kotetezeka kwa ndimeyi. Imamangidwa ndi bolt kapena kupotoza ku thupi la valve kuti ichotsedwe kuti ilowe m'malo kapena kukonza. Kutengera ndikugwiritsa ntchito, ma bonaneti amitundu yosiyanasiyana amaphatikizira ma boniti a bawuti, ma boneti opindika, ma bonaneti a mgwirizano, ndi ma bonaneti osindikizira.
Mapulogalamu
Ma valve a zipatakapena ma sluice ma valve ali ndi ntchito zambiri m'mafakitale osiyanasiyana ndipo amagwiritsa ntchito mosiyanasiyana pakuwongolera madzi, gasi, ngakhalenso kutuluka kwa mpweya. M'malo ovuta kwambiri achilengedwe monga kutentha kwambiri kapena kupanikizika kwambiri m'mafakitale a petrochemical, ma valve a zipata ndi chida chopitira. Zikatero, zinthu ndi mtundu wa valavu zimagwira ntchito yofunika kwambiri pakugwira ntchito ndi mphamvu ya valve.
Ma valve a zipata amapezanso ntchito yawo mu machitidwe otetezera moto, kumene avalavu ya chipata cha flangedamagwiritsidwa ntchito kwambiri.Mavavu apachipata osakweraamagwiritsidwa ntchito m'zombo kapena pansi pa nthaka pamalo omwe malo oyima ali ochepa.
