Jwalo ka karolo ya taolo ya bohlokwa tsamaisong ya diphaephe tsa mokelikeli, di-valve di na le mefuta e fapaneng ya kgokelo ho ikamahanya le maemo a fapaneng a tshebediso le dibopeho tsa mokelikeli. Tse latelang ke mefuta e tlwaelehileng ya kgokelo ya di-valve le ditlhaloso tsa tsona tse kgutshwane:
1. Khokahano ea Flange
Valve kee hokahantsoe le phaephe ka ho bapisa li-flange le li-bolt fasteners, 'me e loketse litsamaiso tsa liphaephe tse nang le mocheso o phahameng, khatello e phahameng le bophara bo boholo.
monyetla:
Kgokelo e tiile mme ho kwala ho hotle. E loketse kgokelo ya di-valve tlasa maemo a thata a kang kgatello e phahameng, mocheso o phahameng le metswedi ya ho senya.
Ho bonolo ho qhaqha le ho lokisa, e leng se etsang hore ho be bonolo ho hlokomela le ho nkela valve sebaka.
bofokoli:
Ho hlokahala libolute le linate tse ngata bakeng sa ho kenya, 'me litšenyehelo tsa ho kenya le ho hlokomela li phahame.
Likhokahano tsa flange li boima haholo 'me li nka sebaka se seholo.
Khokahano ea Flange ke mokhoa o tloaelehileng oa ho hokahanya valve, 'me litekanyetso tsa eona li kenyelletsa lintlha tse latelang haholo-holo:
Mofuta oa Flange: Ho ea ka sebopeho sa bokaholimo bo hokahanyang le sebopeho sa ho tiisa, li-flange li ka aroloa kali-flange tse bataletseng tsa ho tjheseletsa, li-flange tsa ho tjheseletsa tsa butt, li-flange tse hlephileng tse hlephileng, jj.

Boholo ba Flange: Boholo ba flange hangata bo hlahisoa ka bophara bo tloaelehileng (DN) ba phaephe, 'me boholo ba flange ba maemo a fapaneng bo ka fapana.

Sekgahla sa kgatello ya Flange: Sekgahla sa kgatello ya kgokelo ya flange hangata se emelwa ke PN (sekgahla sa Yuropa) kapa Sehlopha (sekgahla sa Amerika). Dikgahla tse fapaneng di tsamaellana le maemo a fapaneng a kgatello ya mosebetsi le a mocheso.

Sebopeho sa bokaholimo ba ho kwala: Ho na le mefuta e fapaneng ya dibopeho tsa ho kwala tsa di-flange, tse kang bokaholimo bo bataletseng, bokaholimo bo phahamisitsweng, bokaholimo bo kobehileng le bo kobehileng, bokaholimo ba leleme le mokoti, jj. Sebopeho se loketseng sa bokaholimo ba ho kwala se lokela ho kgethwa ho latela dibopeho tsa mokelikeli le ditlhoko tsa ho kwala.

2. Khokahano e nang le khoele
Likhokahano tse nang le khoele li sebelisoa haholo-holo bakeng sa li-valve tse bophara bo bonyenyane le litsamaiso tsa liphaephe tse nang le khatello e tlase. Litekanyetso tsa eona li kenyelletsa haholo-holo lintlha tse latelang:
monyetla:
Ho bonolo ho hokela le ho sebetsa habonolo, ha ho hlokahale lisebelisoa kapa lisebelisoa tse khethehileng.

E loketse ho hokela di-valve tse nyane tse bophara bo bonyenyane le diphaephe tse nang le kgatello e tlase ka theko e tlase.

bofokoli:
Tshebetso ya ho kwala e fokola haholo mme ho dutla ho ka etsahala.

E loketse feela maemo a khatello e tlase le mocheso o tlase. Bakeng sa maemo a khatello e phahameng le mocheso o phahameng, khokahano e nang le khoele e kanna ea se fihlelle litlhoko.

Likhokahano tse nang le khoele li sebelisoa haholo-holo bakeng sa li-valve tse bophara bo bonyenyane le litsamaiso tsa liphaephe tse nang le khatello e tlase. Litekanyetso tsa eona li kenyelletsa haholo-holo lintlha tse latelang:
Mofuta oa khoele: Mefuta ea khoele e sebelisoang hangata e kenyelletsa khoele ea phaephe, khoele ea phaephe e tapered, khoele ea NPT, jj. Mofuta o nepahetseng oa khoele o lokela ho khethoa ho latela thepa ea phaephe le litlhoko tsa khokahano.

Boholo ba khoele: Boholo ba khoele hangata bo hlahisoa ka bophara bo tloaelehileng (DN) kapa bophara ba phaephe (inch). Boholo ba khoele ba maemo a fapaneng bo ka fapana.

Thepa ea ho koala: Ho netefatsa hore khokahano e tiile, hangata sekontiri se sebelisoa likhoeleng kapa thepa ea ho koala e kang theipi ea ho koala e sebelisoa.

3. Khokahano ea ho tjheseletsa
Valve le phaephe di kopantswe ka ho toba ka tshebetso ya ho tjheseletsa, e leng se loketseng maemo a hlokang ho kwalwa haholo le kgokelo ya kamehla.
monyetla:
E na le matla a ho hokela a phahameng, ts'ebetso e ntle ea ho koala le ho hanyetsa mafome. E loketse liketsahalo tse hlokang ts'ebetso e sa feleng le e phahameng ea ho koala, joalo ka litsamaiso tsa liphaephe indastering ea peterole, lik'hemik'hale le tse ling.

bofokoli:
E hloka lisebelisoa tsa tjheseletsa tsa profeshenale le basebetsi ba tsona, 'me litšenyehelo tsa ho kenya le ho hlokomela li phahame.

Hang ha ho tjheseletsa ho phethetswe, valve le phaephe di tla bopa kaofela, e leng ntho e seng bonolo ho e qhaqha le ho e lokisa.

Likhokahano tse tjheseditsweng di loketse maemo a hlokang ho kwalwa ho hoholo le dikgokelo tsa kamehla. Maemo a yona a kenyeletsa haholo-holo dintlha tse latelang:
Mofuta oa ho tjheseletsa: Mefuta e tloaelehileng ea ho tjheseletsa e kenyelletsa ho tjheseletsa ha marago, ho tjheseletsa ha fillet, jj. Mofuta o loketseng oa ho tjheseletsa o lokela ho khethoa ho latela thepa ea phaephe, botenya ba lebota le litlhoko tsa khokahano.

Ts'ebetso ea ho tjheseletsa: Khetho ea ts'ebetso ea ho tjheseletsa e lokela ho nahanoa ka botlalo ho latela lintlha tse kang thepa, botenya le boemo ba ho tjheseletsa ba tšepe ea motheo ho netefatsa boleng ba ho tjheseletsa le matla a khokahano.

Tlhahlobo ea ho tjheseletsa: Kamora hore ho tjheseletsa ho phetheloe, ho lokela ho etsoa liteko le liteko tse hlokahalang, joalo ka tlhahlobo ea pono, liteko tse sa senyeheng, jj., ho netefatsa boleng ba ho tjheseletsa le ho tiea ha khokahano.

4. Khokahano ea sokete
Qetello e 'ngoe ea valve ke sokete 'me pheletso e 'ngoe ke spigot, e hokahanngoang ka ho kenngoa le ho koaloa. Hangata e sebelisoa lits'ebetsong tsa liphaephe tsa polasetiki.
5. Kgokelo ya clamp: Ho na le disebediswa tsa clamp mahlakoreng ka bobedi a valve. Valve e kentswe hodima phaephe ka sesebediswa sa clamp, se loketseng ho kenngwa le ho qhaqhwa ka potlako.
6. Kgokelo ya ho seha lesira: Kgokelo ya ho seha lesira hangata e sebediswa ditsamaisong tsa diphaephe tsa polasetiki. Kgokelo pakeng tsa diphaephe le di-valve e fihlellwa ka disebediswa tse ikgethang tsa ho seha le di-fitting tsa ho seha lesira. Mokgwa ona wa kgokelo o bonolo ho o kenya le ho o qhaqha.
7. Kgokelo ya sekgomaretsi
Likhokahano tsa sekhomaretsi li sebelisoa haholo-holo lits'ebetsong tse ling tsa liphaephe tse seng tsa tšepe, joalo ka PVC, PE le liphaephe tse ling. Khokahano ea kamehla e etsoa ka ho kopanya phaephe le valve hammoho ho sebelisoa sekhomaretsi se khethehileng.
8. Khokahano ea clamp
Hangata e bitsoa khokahano e nang le li-groove, ena ke mokhoa oa khokahano o potlakileng o hlokang li-bolt tse peli feela 'me o loketse li-valve tse nang le khatello e tlase tse atisang ho qhaqhoa. Lisebelisoa tsa eona tsa liphaephe tse hokahanyang li kenyelletsa lihlopha tse peli tse kholo tsa lihlahisoa: ① lisebelisoa tsa liphaephe tse sebetsang e le litiiso tsa khokahano li kenyelletsa manonyeletso a thata, manonyeletso a tenyetsehang, li-tee tsa mechini le li-flange tse nang le li-groove; ② lisebelisoa tsa liphaephe tse sebetsang e le liphetoho tsa khokahano li kenyelletsa li-elbow, li-tee, le li-cross, li-reducer, blind plate, jj.
Sebopeho sa khokahano ea valve le maemo ke lintlha tsa bohlokoa ho netefatsa ts'ebetso e sireletsehileng le e tšepahalang ea sistimi ea valve le ea liphaephe. ​​Ha ho khethoa foromo e loketseng ea khokahano, lintlha tse kang thepa ea phaephe, khatello ea ts'ebetso, mocheso o fapaneng, tikoloho ea ho kenya le litlhoko tsa tlhokomelo li lokela ho nahanoa ka botlalo. Ka nako e ts'oanang, litekanyetso le litlhaloso tse amehang li lokela ho lateloa nakong ea ts'ebetso ea ho kenya ho netefatsa ho nepahala le ho koaloa ha likhokahano ho netefatsa ts'ebetso e tloaelehileng ea sistimi ea liphaephe tsa mokelikeli.
