Isingeniso kuma-Ball valves

Ama-valve ebhola

Ivalvu yebhola iyivalvu ejikelezayo ejikelezayo esebenzisa idiski emise okwebhola ukuze ime noma iqale ukugeleza. Uma i-valve ivuliwe, ibhola lizungeza lifike endaweni lapho imbobo ebholeni ihambisana ne-valve body inlet kanye ne-outlet. Uma i-valve ivaliwe, ibhola liyazungezwa ukuze imbobo ibe yi-perpendicular ekuvulekeni kokugeleza komzimba we-valve futhi ukugeleza kumiswe.

Izinhlobo zama-valve eBhola

Amavalvu ebhola atholakala ngezinguqulo ezintathu: imbobo egcwele, imbobo ye-venturi kanye nembobo encishisiwe. I-valve yembobo egcwele inobubanzi bangaphakathi obulingana nobubanzi bangaphakathi bepayipi. I-Venturi nezinguqulo zezimbobo ezincishisiwe ngokuvamile zingusayizi wepayipi owodwa omncane kunosayizi womugqa.

Ama-valve ebhola akhiqizwa ngezindlela ezihlukahlukene zomzimba futhi ezivame kakhulu yilezi:

• Indawo yokungena ephezulu Amavalvu ebhola avumela ukufinyelela kumavalvu angaphakathi ukuze anakekele ngokususa ikhava yebhonethi yevalvu. Akudingekile ukukhishwa kwe-valve ohlelweni lwepayipi.
• I-Split body Ball valves iqukethe izingxenye ezimbili, lapho ingxenye eyodwa incane njengenye. Ibhola lifakwa engxenyeni enkulu yomzimba, futhi ingxenye encane yomzimba ihlanganiswa ngokuxhuma okuboshiwe.

Iziphetho ze-valve ziyatholakala njenge-butt welding, i-socket welding, i-flanged, i-threaded nabanye.

Izinto zokwakha

Amabhola ngokuvamile enziwa ngezinsimbi ezimbalwa, kuyilapho izihlalo zivela ezintweni ezithambile ezifana ne-Teflon®, i-Neoprene, nezinhlanganisela zalezi zinto. Ukusetshenziswa kwezinto zezihlalo ezithambile kunikeza ikhono elihle kakhulu lokuvala. Ukungalungi kwezinto ze-soft-seat (izinto ze-elastomeric) ukuthi azikwazi ukusetshenziswa ezinkambisweni zokushisa okuphezulu.

Isibonelo, izihlalo ze-polymer ezine-fluorinated zingasetshenziselwa amazinga okushisa asuka ku-−200° (nangaphezulu) kuya ku-230°C nangaphezulu, kuyilapho izihlalo ze-graphite zingasetshenziswa emazingeni okushisa asuka ku-?° ukuya ku-500°C nangaphezulu.

Umklamo wesiqu

Isiqu esikwivalvu yeBhola asixhunywanga ebholeni. Ivamise ukuba nengxenye engunxande ebholeni, futhi leyo ingena esikhaleni esisikwe ebholeni. Ukwandiswa kuvumela ukuzungeza kwebhola njengoba ivalvu ivulwa noma ivaliwe.

Ibhonethi yevalvu yebhola

Ibhonethi yevalvu yeBhola iboshelwa emzimbeni, ebamba ukuhlangana kwesiqu kanye nebhola endaweni. Ukulungiswa kwebhonethi kuvumela ukucindezelwa kokupakisha, okunikeza uphawu lwe-stem. Impahla yokupakisha yeziqu ze-valve ye-Ball ngokuvamile i-Teflon® noma i-Teflon-filled noma i-O-rings esikhundleni sokupakisha.

Ball valve izicelo

Okulandelayo ezinye izinhlelo zokusebenza ezijwayelekile zama-valve eBhola:

• Izicelo zomoya, igesi, noketshezi
• Imisele kanye nezintuba kuketshezi, igesi, nezinye izinsiza zoketshezi
• Isevisi ye-Steam

Izinzuzo kanye Nebubi bamavalvu ebhola

Izinzuzo:

• Umsebenzi wokuvala ikota esheshayo
• Ukuvalwa okuqinile ngetorque ephansi
• Mancane ngosayizi kunamanye ama-valve amaningi

Ububi:

• Ama-valve e-Ball ajwayelekile anezindawo zokudonsa kanzima
• Ngodaka noma ezinye izinhlelo zokusebenza, izinhlayiya ezimisiwe zingahlala futhi zivaleleke emigodini yomzimba ebangela ukuguga, ukuvuza, noma ukwehluleka kwamavalvu.
