E le ntho ea bohlokoa ea taolo tsamaisong ea lipeipi tsa mokelikeli, li-valve li na le mefuta e fapaneng ea khokahano ho ikamahanya le maemo a fapaneng a ts'ebeliso le litšobotsi tsa mokelikeli. Tse latelang ke liforomo tse tloaelehileng tsa khokahano ea li-valve le litlhaloso tsa tsona tse khutšoane:
1. Khokahano ea Flange
Belofo kee hokahaneng le liphaephe ka ho tsamaisana le li-flange le li-fasteners tsa bolt, 'me e loketse mocheso o phahameng, khatello e phahameng le tsamaiso e kholo ea lipeipi tsa bophara.
molemo:
Khokahano e tiile 'me tiiso e ntle. E loketse ho hokahanya ha valve tlas'a maemo a thata a kang khatello e phahameng, mocheso o phahameng le mecha ea litaba e senyang.
Ho bonolo ho qhaqha le ho lokisa, ho etsa hore ho be bonolo ho hlokomela le ho fetola valve.
khaello:
Ho hlokahala liboutu le linate tse ngata bakeng sa ho kenya, 'me litšenyehelo tsa ho kenya le ho li lokisa li phahame.
Likhokahano tsa flange li batla li le boima 'me li nka sebaka se eketsehileng.
Khokahano ea Flange ke mokhoa o tloaelehileng oa khokahano ea li-valve, 'me maemo a eona a kenyelletsa lintlha tse latelang:
Mofuta oa Flange: Ho ea ka sebopeho sa sebaka se kopanyang le sebopeho sa ho tiisa, li-flange li ka aroloali-flange tse bataletseng, li-flange tsa welding, li-sleeve flanges tse hlephileng, joalo-joalo.

Boholo ba flange: Boholo ba flange hangata bo hlahisoa ka bophara ba lebitso (DN) la phala, 'me boholo ba flange ba litekanyetso tse fapaneng bo ka fapana.

Mokhahlelo oa khatello ea Flange: Khatello ea khatello ea khokahanyo ea flange hangata e emeloa ke PN (Tekanyetso ea Europe) kapa Sehlopha (Tekanyetso ea Amerika). Limaraka tse fapaneng li lumellana le khatello e fapaneng ea ho sebetsa le mefuta ea mocheso.

Sebopeho sa holim'a ho tiisa: Ho na le mefuta e fapaneng ea ho tiisa holim'a li-flanges, joalo ka bokaholimo bo bataletseng, bokaholimo bo phahamisitsoeng, bokaholimo ba concave le convex, leleme le bokaholimo ba groove, joalo-joalo.

2. Khokahano ea likhoele
Mahokelo a likhoele a sebelisoa haholo-holo bakeng sa li-valve tsa bophara bo nyane le lipeipi tsa khatello e tlase. Litekanyetso tsa eona li kenyelletsa haholo lintlha tse latelang:
molemo:
Ho bonolo ho hokahanya le ho sebetsa habonolo, ha ho na lisebelisoa tse khethehileng kapa lisebelisoa tse hlokahalang.

E loketse bakeng sa ho hokahanya li-valve tse nyenyane tsa bophara le liphaephe tsa khatello e tlaase ka theko e tlaase.

khaello:
Ts'ebetso ea ho tiisa e batla e fokola 'me ho na le monyetla oa ho lutla.

E loketse feela khatello e tlaase le maemo a tlaase a mocheso. Bakeng sa maemo a phahameng a khatello le mocheso o phahameng, khokahanyo ea threaded e ka 'na ea se ke ea finyella litlhoko.

Mahokelo a likhoele a sebelisoa haholo-holo bakeng sa li-valve tsa bophara bo nyane le lipeipi tsa khatello e tlase. Litekanyetso tsa eona li kenyelletsa haholo lintlha tse latelang:
Mofuta oa khoele: Mefuta ea likhoele e sebelisoang ka tloaelo e kenyelletsa khoele ea phala, khoele ea phala e tapered, khoele ea NPT, joalo-joalo Mofuta o nepahetseng oa khoele o lokela ho khethoa ho latela thepa ea phala le litlhoko tsa khokahano.

Boholo ba khoele: Boholo ba khoele hangata bo hlahisoa ka bophara ba lebitso (DN) kapa bophara ba phala (inch). Boholo ba khoele ea litekanyetso tse fapaneng bo ka fapana.

Lisebelisoa tsa ho tiisa: Ho etsa bonnete ba ho tiea ha khokahano, sealant hangata e sebelisoa likhoeleng kapa lisebelisoa tsa ho tiisa joalo ka tepi ea ho tiisa.

3. Khokahano ea tjheseletsa
Belofo le phala li kopantsoe ka ho toba hammoho ka mokhoa oa ho cheselletsa, o loketseng maemo a hlokang ho tiisoa ho phahameng le ho hokahanya ka ho sa feleng.
molemo:
E na le matla a holimo a khokahanyo, ts'ebetso e ntle ea ho tiisa le ho hanyetsa kutu. E loketse liketsahalo tse hlokang ts'ebetso ea ho tiisa ka ho sa feleng le e phahameng, joalo ka lits'ebetso tsa liphaephe tsa peterole, lik'hemik'hale le liindasteri tse ling.

khaello:
E hloka lisebelisoa le li-operators tsa litsebi, 'me litšenyehelo tsa ho kenya le ho li boloka li phahame.

Hang ha tjheseletsa e phethiloe, valve le phala li tla theha kaofela, tseo ho seng bonolo ho li qhaqha le ho li lokisa.

Lihokelo tse cheselitsoeng li loketse maemo a hlokang tiiso e phahameng le likhokahano tsa ka ho sa feleng. Litekanyetso tsa eona li kenyelletsa haholo lintlha tse latelang:
Mofuta oa weld: Mefuta e tloaelehileng ea li-weld e kenyelletsa li-welds tsa butt, li-welds tsa fillet, joalo-joalo Mofuta o loketseng oa weld o lokela ho khethoa ho ea ka thepa ea phala, botenya ba lerako le litlhoko tsa ho hokahanya.

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

Tlhahlobo ea Welding: Kamora hore welding e phetheloe, tlhahlobo le liteko tse hlokahalang li lokela ho etsoa, ​​​​joalo ka tlhahlobo ea pono, tlhahlobo e sa senyeheng, joalo-joalo, ho netefatsa boleng ba welding le ho tiea ha khokahano.

4. Socket connection
Qetello e 'ngoe ea valve ke sokete 'me ntlha e' ngoe ke spigot, e kopantsoeng ka ho kenya le ho tiisa. Hangata e sebelisoa lits'ebetsong tsa liphaephe tsa polasetiki.
5. Khokahano ea li-clamp: Ho na le lisebelisoa tsa ho koala mahlakoreng ka bobeli a valve. Valve e tsitsitse pompong ka sesebelisoa sa clamping, se loketseng ho kenngoa ka potlako le ho qhaqha.
6. Khokahano ea sleeve ea ho itšeha: Khokahano ea matsoho ea ho itšeha hangata e sebelisoa litsing tsa liphaephe tsa polasetiki. Kamano pakeng tsa liphaephe le li-valve e finyelloa ka lisebelisoa tse khethehileng tsa ho itšeha le lisebelisoa tsa ho itšeha. Mokhoa ona oa ho hokahanya o bonolo ho kenya le ho qhaqha.
7. Khokahano e khomarelang
Likhokahano tsa likhomaretsi li sebelisoa haholo litsing tse ling tsa liphaephe tse seng tsa tšepe, joalo ka PVC, PE le liphaephe tse ling. Khokahano ea ka ho sa feleng e etsoa ka ho kopanya phala le valve hammoho ho sebelisa sekhomaretsi se khethehileng.
8. Khokahano ea clamp
Hangata e bitsoa grooved connection, ona ke mokhoa o potlakileng oa ho hokahanya o hlokang liboutu tse peli feela 'me o loketse li-valve tsa khatello e tlaase tse atisang ho qhaqha. Lisebelisoa tsa eona tsa liphaephe tse hokelang li kenyelletsa likarolo 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-tees tsa mochini le li-flange tse kobehileng; ② lisebelisoa tsa liphaephe tse sebetsang e le phetisetso ea khokahanyo li kenyelletsa likhama, lithapo le lifapano, se fokotsang, poleiti e foufetseng, joalo-joalo.
Foromo ea khokahano ea li-valve le maemo a tloaelehileng ke lintlha tsa bohlokoa ho netefatsa ts'ebetso e bolokehileng le e ts'epahalang ea valve le sistimi ea liphaephe. Ha u khetha foromo e nepahetseng ea ho hokahanya, lintlha tse kang thepa ea liphaephe, khatello ea ho sebetsa, sebaka sa mocheso, tikoloho ea ho kenya, le litlhoko tsa tlhokomelo li lokela ho nkoa 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 tiisoa ha likhokahano ho netefatsa ts'ebetso e tloaelehileng ea tsamaiso ea lipeipi tsa mokelikeli.
