Mohala o le Mong oa Counterbalance Valve

Valve e ne e sebelisetsoa ho laola ho sisinyeha le ho koala ha actuator ka tsela e le 'ngoe ka ho lemoha ho theoha ho laoloang ha mojaro o sa baleheng ho huloa ke boima ba oona, kaha valve ha e lumelle leha e le efe cavitation ea actuator.

Li-valve tsa 5160B single overcenter tsa letoto li etselitsoe ho netefatsa botsitso boemong ba ho sebetsa ba hydraulic actuator e nang le mojaro o emisitsoeng, le ho laola motsamao oa eona ka nqa e le 'ngoe feela (hangata karolo ea ho theoha), e siea lehlakore le fapaneng le tsamaisoa ke phallo e sa lefelloeng. ; ka lebaka la boema-kepe ba likhoele tsa BSPP-GAS, e ka kenngoa kahare ho sistimi ea hydraulic. Ka ho fepa mohala o shebaneng le mojaro, mohala oa sefofane o laola ho buleha ha karolo e itseng ea mocha o theohang o lumellang taolo ea motsamao oa actuator le ho qoba ketsahalo ea cavitation ka lebaka la ketso ea ho bapisa matla a khoheli.

Lesoba le lekantsoeng le nyenyefatsa lets'oao la sefofane e le hore valve e bulehe le ho koala ka ho lekana, ho qoba ho sisinyeha ha mojaro. The 5160B single overcenter valve e boetse e sebetsa e le antishock valve boteng ba litlhōrō tsa khatello tse bakoang ke liphello kapa meroalo e feteletseng. E le hore sena se khonehe, mohala oa ho khutlela ho mofani oa thepa o tlameha ho hokahanngoa le drainage. 5160B ke valve e lefshoang ka halofo: likhatello tse setseng molaong oa ho khutla ha li ame ho hlophisoa ha valve ha li ntse li eketsa litekanyetso tsa ho khanna.

Tšebeliso ea mofuta ona oa valve e ka khoneha ka mekhoa e nang le DCV e nang le setsi se koetsoeng sa setsi. Hydraulic leakproof ke karolo ea bohlokoa bakeng sa li-valve tsa overcenter. Ho etsa bonnete ba ts'ebetso e ntle ka ho fetisisa, Bost e etsa likarolo tsa ka hare tsa li-valve tsa eona ka tšepe e matla e phahameng, e thata le e sila, 'me, nakong ea ts'ebetso ea tlhahiso, e hlahloba ka hloko litekanyo le mamello ea geometri ea likarolo tsa ho tiisa, hammoho le tiiso ka boeona. belofo e kopaneng. 5160B ke li-valve tsa likarolo tsa 'mele: likarolo tsohle li kenngoa ka har'a motsoako oa li-hydraulic, tharollo e lumellang ho laola litekanyetso tse phahameng tsa phallo ha ho ntse ho fokotsa litekanyo tse akaretsang.

Mefuta e mengata e entsoe ka tšepe bakeng sa likhatello tsa ts'ebetso ho fihlela ho 350 bar (5075) le khanyetso e phahameng ea ho apara; e sirelelitsoe ho bola ka kalafo ea zinc plating mme e entsoe ka mochini lifahlehong tse tšeletseng bakeng sa ts'ebetso e ntle ea kalafo ea bokaholimo. Bakeng sa lits'ebetso tse pepesehetseng lintho tse senyang ka ho khetheha (mohlala, likopo tsa marine) kalafo ea Zinc-Nickel e fumaneha ka kopo. Li-valve tsa 5160B li fumaneha ka boholo ba BSPP 3/8" le BSPP 1/2" bakeng sa litefiso tse khothalelitsoeng tsa phallo ea ho sebetsa ho fihla ho 60 lpm (15). , 9 gpm).
