Tšebeliso ea valve e kholo ea moea ea serurubele ka li-valve tsa indasteri

Ho sebelisoa ha belofo ea serurubele se nang le moea o molelele ka har'a li-valve tsa indasteri (1) Hokela belofo ka khoele. Khokahano ena hangata E ETSOA KA HO HLAHISA ALVE INLET LE OUTLET E QETELA KA LITLHALE TSA LIPHAPE TSE TLOTSENG KAPA TSE KA HOKELANG HO MAHOHETSOA KAPA LINTLHA TSA PIPE E TAPERED. Ka lebaka la monyetla oa likanale tse kholo tsa ho lutla khokahanong ena, likanale tsena li ka thijoa ka sealant, theipi e koalang, kapa ho paka. Haeba thepa EA 'mele oa belofo ka tjheseletsa, empa coefficient ea katoloso e fapane haholo, kapa mefuta e fapaneng ya mefuta e fapaneng ya mocheso tshebetso e khōlō, khokahanyo threaded e lokela ho ba mahe a linotsi tiisitsoe tjheseletsa. Khokahano e likhoele ea valve haholo-holo ke meridian ka lebitso la valve e latelang ea 50mm. Haeba boholo ba bophara bo le boholo haholo, ho thata haholo ho kenya le ho tiisa motsoako. Ho thusa ho kenya le ho tlosoa ha li-valve tse nang le likhoele, li-connectors li fumaneha libakeng tse loketseng tsamaisong ea liphaephe. Li-valve tse fihlang ho 50mm ka boholo bo tloaelehileng li ka sebelisa lenonyeletso la letsoho joalo ka lenonyeletso, ka likhoele tse kopanyang likarolo tse peli tsa lenonyeletso. (2) valve ea ho hokahanya ha flange. Li-valve tse nang le flanged li bonolo ho kenya le ho li tlosa. Empa li ngata ho feta li-valve tse khoele, 'me ka tsela e tšoanang li bitsa chelete e ngata. Ka hona, e loketse ho hokahanya liphaephe tsa boholo bo fapaneng le likhatello. Leha ho le joalo, ha mocheso o feta likhato tse 350, ka lebaka la ho lokoloha ha liboutu, li-gaskets le li-flanges, tseo hape li fokotsang mojaro oa liboutu, ho lutla ho ka etsahala ho likhokahano tsa flange tse hatelitsoeng haholo. (3) Weld valve. Khokahano ena e loketse mefuta eohle ea khatello le mocheso, 'me e tšepahala ho feta khokahanyo ea flanged ha e sebelisoa tlas'a maemo a boima. Empa ho qhaqhoa le ho kenya li-valve ho thata ho feta, kahoo tšebeliso ea eona e lekanyelitsoe hore hangata e ka sebetsa ka botšepehi ka nako e telele, kapa ea sebelisa maemo a ho laela, liketsahalo tse phahameng tsa mocheso. Joalo ka seteishene sa motlakase oa mocheso, projeke ea matla a nyutlelie, projeke ea ethylene e mabapi le lipeipi. Li-valve tse cheselitsoeng tse nang le li-diameter tse ka holimo ho 50mm hangata li na le li-jacks tse cheselitsoeng ho tšoara phala qetellong ea mojaro. Hobane socket welding e etsa lekhalo pakeng tsa sokete le pipeline, e leng se ka etsang hore lekhalo le senngoe ke mecha e meng ea litaba, 'me ho sisinyeha ha pipeline ho tla etsa hore karolo e kopanetsoeng e khathale, kahoo tšebeliso ea socket welding e fokotsehile. Ka bophara ka lebitso le leholo, tšebeliso ea maemo a ho laela, mocheso o phahameng, 'mele oa belofo o atisa ho amohela welding ea groove, ka nako e ts'oanang, lenonyeletso la welding le na le litlhoko tsa pele, le tlameha ho khetha mochine o matla oa botekgeniki ho qeta mosebetsi oa Ventilation e kholo ea bophara. Serurubele belofo tšebeliso ea li-valve tsa indasteri Hona joale naha ea rona liindasteri tse sa tšoaneng bakeng sa belofo tšepe, belofo ho pharaletseng sebelisoa tlhahiso ea tšepe belofo sebelisoa ka makholo a lilemo tsa histori, e nang le ka ntlafatso ea sebopeho le thepa, empa ka mefokolo ea eona, lisebelisoa tsa tšepe li ntse li eketseha ha li khone ho ikamahanya le maemo a mabe a ho sebetsa, ho roala ho matla joalo ka holimo le ho senya. Haholo-holo e bontšitsoeng bophelong bo bokhutšoanyane ba tšebeletso, ho lutla ho ile ha ama ka ho teba botsitso ba ts'ebetso ea tsamaiso. Valve ea setso ea tšepe e hloka ka potlako boqapi bo phethahetseng mabapi le thepa, moralo le ts'ebetso ea tlhahiso. Hona joale, valve e atisang ho sebelisoa ha ho etsoa liindasteri tse sa tšoaneng naheng ea rona ke valve ea tšepe. Tšebeliso ea valve ea tšepe e 'nile ea e-ba lilemo tse fetang lekholo tsa histori. Le hoja e ntlafalitsoe ka sebopeho le lisebelisoa, ha e khone ho finyella litlhoko tsa ho roala holimo, ho senya ho matla le maemo a mang a thata a ho sebetsa. Haholo-holo e bontšitsoeng bophelong bo bokhutšoanyane ba tšebeletso, ho lutla ho ile ha ama ka ho teba botsitso ba ts'ebetso ea tsamaiso. Valve ea setso ea tšepe e hloka ka potlako boqapi bo phethahetseng mabapi le thepa, moralo le ts'ebetso ea tlhahiso. Lisebelisoa tsa ceramic tse tsoetseng pele, e le thepa e ncha lekholong la bo21 la lilemo, li 'nile tsa nkoa ka botebo ke basebetsi ba bangata ba saense. Ke ts'ebetso e sebete le e molemo ho e sebelisa ho li-valve tsa indasteri. Lisebelisoa tsa ceramic li na le deformation e nyane haholo le matla a holimo haholo a tlamang ho feta litšepe. Ka kakaretso, radius ea crystalline ionic ea lisebelisoa tsa ceramic e nyane, 'me theko ea motlakase ea ionic e phahame,' me palo ea khokahano e kholo. Thepa ena e etsa qeto ea matla a ho tiea, matla a khatello, modulus ea elastic le ho thatafala ha lisebelisoa tsa ceramic li phahame haholo. Ceramic ka boeona, leha ho le joalo, "brittle" le ts'ebetso e thata e fokotsa boholo ba ts'ebeliso ea lilemo tse mashome tsa morao tjena, ka lebaka la thekenoloji e matla ea phetoho ea martensitic, lisebelisoa tse ngata tsa saense le theknoloji le nts'etsopele le tsoelo-pele ea mohopolo oa nanometer ceramics e entsoeng ka letsopa le porcelain. "brittle" e na le * * ho ntlafatsa, ho tiea le matla ho ntlafalitsoe haholo, ho holisa mefuta ea likopo. Valve ea ceramic e sa sebetseng e sebelisoa haholo ho matla a motlakase, peterole, indasteri ea lik'hemik'hale, metallurgy, merafo, likhoerekhoere le masimo a mang a indasteri, haholoholo ha ho tobane le ho roala ho hoholo, kutu e matla, mocheso o phahameng, khatello e phahameng le maemo a mang a thata a ho sebetsa. empa hape e bonts'a ts'ebetso ea eona e ntle ka ho fetisisa. E ka kopana le ts'ebeliso ea moaparo o phahameng, tikoloho e matla ea kutu, haholo-holo tšobotsi e hlahelletseng ke bophelo bo bolelele ba ts'ebeletso, tekanyo ea theko ea ts'ebetso ea eona e ntle haholo ho feta li-valve tse ling tse tšoanang tsa tšepe. Ka tsoelo-pele e tsoelang pele le tsoelo-pele ea saense le thekenoloji, lisebelisoa tsa ceramic tse tsoang ho theho, ho bōpa, ho sebetsa le theknoloji ea kopano le likarolo tse ling tsa theknoloji li hōlile le ho phetheha, valve ea ceramic e nang le ts'ebetso ea eona e babatsehang ho fumana kananelo ea batho ba indasteri. . Phihlelo e atlehileng ea ho etsa li-valve tsa ceramic le eona e ka sebelisoa masimong a tsoetseng pele a boenjiniere.
