China Ts'ebetso e phahameng ea li-valve tsa bolo ea likotoana tse peli tsa motlakase - taolo e nepahetseng ea phallo le ts'ebetso e hole
1. Valve ena e ncha ea bolo e etselitsoe ho fana ka taolo e nepahetseng ea phallo le ho ts'ehetsa mesebetsi e bonolo ea ts'ebetso e hole. E entsoe ka thepa ea boleng bo phahameng, e tiisa ho tšoarella ho babatsehang le ho tšepahala. Moqapi oa likarolo tse peli ha o etse feela hore valve e be bonolo ho e boloka empa e boetse e fokotsa tšitiso ea ts'ebetso ea tsamaiso ea liphaephe. E na le actuator ea motlakase, e fana ka torque e phahameng e hlokahalang bakeng sa ts'ebetso e boreleli le ho tiisa hantle, leha ho na le phapang e phahameng ea khatello. Ka likarolo tsa eona tse tsoetseng pele le kaho ea boleng bo phahameng, valve ena ea motlakase e nang le khoele ea motlakase ke khetho e ka tšeptjoang bakeng sa ho finyella taolo e ntle ea phallo lits'ebetsong tse fapaneng tsa indasteri.
Litekanyetso tsa tekheniki:
- Mokhoa oa khokahanyo: khokahanyo ea khoele, e tsamaellanang le litekanyetso tsa machaba tse kang ISO 7-1

- Torque: Ho ea ka boholo le litlhoko tsa khatello ea valve, fana ka torque e lekaneng ho netefatsa ho bula le ho koala hantle ha valve.
- Mofuta oa sehokelo: Lisebelisoa tsa maikutlo tsa boemo ba boikhethelo joalo ka matšoao a mochini, li-sensor tsa haufi kapa li-switches tse fokolang
Boholo le thepa:
- Boholo: Mefuta e tloaelehileng e kenyelletsa DN15, DN20, DN25, DN32, DN40, DN50, joalo-joalo, e ka etsoang ha ho hlokahala.
- Boitsebiso: 'mele oa valve hangata o entsoe ka tšepe e sa hloekang kapa carbon steel, kutu ea valve hangata e entsoe ka tšepe e sa hloekang,' me setulo sa valve le likarolo tse ling tsa ho tiisa li ka etsoa ka lisebelisoa tse sa tšoaneng tse akarelletsang PTFE le EPDM.
Ka kopo hlokomela hore litekanyo tse kaholimo tsa tekheniki, boholo le likhetho tsa thepa li ka fapana ho latela bahlahisi ba fapaneng le litlhoko tsa 'nete tsa kopo. Ha u khetha, litlhaloso tse nepahetseng tsa li-valve le lisebelisoa li lokela ho khethoa ho ea ka maemo a sebele a ho sebetsa.
2. Indasteri-grade-li-piece electric threaded ball valve - moralo o thibelang ho bola ho ntlafatsa ts'epo ea tsamaiso.
Valve ea bolo ea liindasteri ea mekhahlelo e 'meli ea liindasteri e sebelisa moralo o tsoetseng pele oa ho thibela kutu, o ntlafatsang ts'epahalo ea sistimi haholo. Valve ea bolo e loketse maemo a thata a ho sebetsa, haholo-holo bakeng sa ho sebetsana le mecha ea litaba e senyang, ho netefatsa ts'ebetso e tsitsitseng ea nako e telele. Sesebelisoa sa motlakase se ts'ehetsa taolo e hole le e ikemetseng ha e ntse e ntlafatsa ho nepahala ha taolo ea phallo.
Litekanyetso tsa tekheniki:

- Mecha ea litaba e sebetsang: metsi, lik'hemik'hale, oli le maro a mang a senyang
-Actuator ea motlakase: khetho ea 4-20mA ea lets'oao, mofuta oa switjha oa 90 ° kapa ts'ebetso ea mofuta oa modulation
- Voltage: standard 24V DC kapa 220V AC, e ka etsoa ho latela litlhoko tsa bareki
- Boemo ba ts'ireletso: hangata IP67 kapa ho feta, e loketse tikoloho e thata
- Letšoao la taolo: le lumellana le taolo e hole le mesebetsi ea ho beha leihlo lits'ebetso tsa othomathike joalo ka SCADA le PLC

- Mofuta oa li-interface: E ka ba le lisebelisoa tsa ho fana ka maikutlo a boemo joalo ka matšoao a mochini, li-sensor tsa haufi kapa li-switches tse fokolang.
Boholo le thepa:
- Boholo: Mefuta e tloaelehileng e kenyelletsa DN15, DN20, DN25, DN32, DN40, DN50, joalo-joalo, e ka etsoang ho latela litlhoko.
- Thepa: Sekoaelo sa valve le sekoaelo sa valve hangata se entsoe ka tšepe e sa hloekang (joalo ka 304L kapa 316L) ho matlafatsa khanyetso ea kutu; kutu ea valve hangata e entsoe ka tšepe e sa hloekang, ha setulo sa valve le thepa ea selikalikoe e tiisang e ka ba Viton (FKM), PTFE kapa lisebelisoa tse ling tse sa cheng.
Ts'ebetsong ea sebele, litlhaloso tsa li-valve, lisebelisoa le litlhoko tsa ho hokahanya ha ts'ebetso tse loketseng maemo a khethehileng a ho sebetsa li lokela ho khethoa ka hloko ho etsa bonnete ba hore valve e ka boloka ts'ebetso e nepahetseng lits'ebetsong tse itseng.
