Tlaleho e lebelletse hore kholo ea GDP ea lefats'e e tla ba 5.8% ka 2021, ha e bapisoa le ponelopele ea pejana ea 5.6%. Tlaleho e boetse e bolela esale pele hore hara diikonomi tsa ditho tsa G20, moruo wa China o tla hola ka 8.5% ka 2021 (ha ho bapiswa le ponelopele ya 7.8% ka Hlakubele selemong sena). Kholo e tsoelang pele le e tsitsitseng ea kakaretso ea moruo oa lefats'e e tsamaisitse nts'etsopele ea liindasteri tsa li-valve tse tlase joalo ka oli le khase ea tlhaho, matla a motlakase, kalafo ea metsi, indasteri ea lik'hemik'hale le kaho ea litoropo, e leng se bakileng nts'etsopele e potlakileng ea indasteri ea li-valve le ts'ebetso ea bohlokoa ea mmaraka. .
A. Boemo ba nts'etsopele ea indasteri ea li-valve tsa China
Ka matsapa a kopanetsweng le popontshwa e ikemetseng ya dikgwebo tsa tlhahiso le mekga e fapaneng, indaseteri ya tlhahiso ya disebediswa tsa dibalofo ya naha ya heso e bile dilemong tsa morao tjena polanteng ya matla a nyutlelie ya dibalofo tsa maemo a nyutlelie, dibalofo tsa bolo tse bophara bo boholo ba diphaephe tsa diphaephe tsa sebaka se selelele tsa kgase ya tlhaho, li-valve tsa bohlokoa bakeng sa li-unit tsa matla a mocheso a phahameng ka ho fetesisa, masimo a petrochemical, le liindasteri tsa liteishene tsa motlakase. Lihlahisoa tse ling tsa li-valve tsa maemo a holimo tlas'a maemo a khethehileng a ho sebetsa li entse tsoelo-pele e ntle, 'me tse ling li finyelletse sebaka sa libaka, tse sa kang tsa nka sebaka sa thepa e tsoang linaheng tse ling, empa hape li ile tsa senya puso ea linaha tse ling, ho khanna phetoho ea indasteri le ntlafatso le tsoelo-pele ea saense le thekenoloji.
B. Mokhoa oa tlholisano oa indasteri ea li-valve tsa China
Indasteri ea tlhahiso ea li-valve tsa China e na le matla a fokolang a therisano bakeng sa indasteri ea lihlahisoa tse tala, palo e kholo ea lihlahisoa tsa lehae tse tlase li maemong a tlholisano ea litheko (serurubele valve,lug serurubele valve, belofo ea serurubele se nang le flanged,belofo ea heke,ho hlahloba valve, etc) 'Me matla a therisano bakeng sa indasteri e tlase le ona ha a lekana; ka ho kena ho tsoelang pele ha lichelete tsa kantle ho naha, mofuta oa eona le likarolo tsa theknoloji Ho kena ha lichelete tsa kantle ho naha ho tla tlisa lits'oso le likhatello tse kholo likhoebong tsa lehae; ho phaella moo, li-valve ke mofuta oa mechine e tloaelehileng, 'me lihlahisoa tsa mechine e tloaelehileng li khetholloa ke ho feto-fetoha ha maemo ho matla, sebopeho se batlang se le bonolo le ts'ebetso e bonolo, e leng se lebisang ho bonolo ho etsa tlhahiso ea ho etsisa ho tla etsa hore ho hahoa ho pheta-pheta le tlhōlisano e sa laoleheng' marakeng. ho na le ts'okelo e itseng ea liemedi.
C. Menyetla ea maraka ea nako e tlang ea li-valve
Li-valve tsa ho laola (li-valve tse laolang) li na le menyetla e pharaletseng ea ho hōla. The valve control, e tsejoang hape e le valve e laolang, ke karolo ea taolo tsamaisong ea ho tsamaisa mokelikeli. E na le mesebetsi e kang ho khaola, ho laola, ho kheloha, ho thibela ho khutlela morao, ho tsitsisa ha motlakase, ho kheloha kapa ho fokotsa khatello ea metsi. Ke e 'ngoe ea likarolo tsa mantlha tsa tlhahiso e bohlale. Masimo a kenyelletsa peterole, petrochemical, lik'hemik'hale, ho etsa pampiri, ts'ireletso ea tikoloho, matla, matla a motlakase, merafo, metallurgy, meriana, lijo le liindasteri tse ling.
Ho latela "China Control Valve Market Research Report" ea ARC, mmaraka oa li-valve tsa taolo ea lapeng o tla feta US $ 2 bilione ka 2019, ka keketseho ea selemo le selemo ea ho feta 5%. Ho lebelletsoe hore sekhahla sa kholo ea selemo le selemo se tla ba 5.3% lilemong tse tharo tse tlang. Mmaraka oa li-valve tsa taolo hajoale o laoloa ke mefuta ea kantle ho naha. Ka 2018, Emerson o ile a etella pele valve ea taolo e phahameng ka karolo ea 'maraka ea 8.3%. Ka ho potlakisa phetoho ea lehae le nts'etsopele ea tlhahiso e bohlale, baetsi ba li-valve tsa taolo ea malapeng ba na le menyetla e metle ea kholo.
Ho nkeloa sebaka ha li-valve tsa hydraulic lapeng ho potlakisa. Likarolo tsa Hydraulic li sebelisoa haholo mefuteng e fapaneng ea mechini ea ho tsamaea, mechini ea indasteri le lisebelisoa tse kholo. Liindasteri tse ka tlaase ho moo li kenyeletsa mechine ea kaho, likoloi, mechine ea tšepe, lisebelisoa tsa mochine, mechine ea merafo, mechine ea temo, likepe le mechine ea peterole. Li-valve tsa Hydraulic ke likarolo tsa mantlha tsa hydraulic. Ka 2019, li-valve tsa hydraulic li ile tsa nka karolo ea 12.4% ea kakaretso ea boleng ba lisebelisoa tsa mantlha tsa hydraulic tsa China (Hydraulic Pneumatic Seals Industry Association), ka boholo ba mmaraka bo ka bang li-yuan tse limilione tse likete tse 10. Hajoale, li-valve tsa naha ea heso tsa maemo a holimo li itšetlehile ka thepa e tsoang kantle ho naha (ka 2020, thepa ea naha ea heso ea hydraulic transmission valve e ne e le li-yuan tse limilione tse 847, 'me thepa e tsoang kantle e ne e le li-yuan tse limilione tse likete tse 9.049). Ka ho potlakisa ho nkela sebaka sa lehae, 'maraka oa naha ea heso oa li-valve tsa haeteroliki o hotse ka potlako.
