Polytetrafluoroethylene (PTFE) e na le matla a ts'enyeho ea ts'enyeho, ts'ebetso e tsitsitseng, ha ho bonolo ho tsofala, coefficient e tlase ea khohlano, ho theha habonolo, boholo bo tsitsitseng, le ts'ebetso ea eona e pharalletseng e ka ntlafatsoa ka ho tlatsa le ho eketsa lisebelisoa tse nepahetseng ho fumana thepa ea ho tiisa serurubele ka matla a matle le coefficient e tlase ea khohlano, e hlolang meeli ea rabara ea maiketsetso. Ka hona, polytetrafluoroethylene (PTFE) ke moemeli oa lisebelisoa tsa polymer polymer Composite le lisebelisoa tsa bona tse tlatsitsoeng li 'nile tsa sebelisoa haholo li-valve tsa serurubele, e le hore ts'ebetso ea li-valve tsa serurubele e ntlafatsoe. Li-valve tsa Butterfly tse nang le mocheso o pharaletseng le khatello ea khatello, ts'ebetso e tiisitsoeng ea ho tiisa le bophelo bo bolelele ba ts'ebeletso bo hlahisitsoe.
Bakeng sa ho fihlela litlhoko tsa mocheso o phahameng le o tlase, khoholeho e matla ea bophelo, bophelo bo bolelele le lits'ebetso tse ling tsa indasteri, sephahla sa tšepe sa serurubele se tiisitsoeng se ntlafalitsoe haholo. Ka ts'ebeliso ea mocheso o phahameng oa mocheso, mocheso o tlase oa ho hanyetsa, ho hanyetsa khoholeho e matla le lisebelisoa tse phahameng tsa alloy ka li-valve tsa serurubele, li-valve tsa serurubele tse tiisitsoeng ka tšepe li sebelisitsoe haholo mocheso o phahameng le o tlase, khoholeho e matla ea bophelo, ts'ebeletso e telele le tse ling masimo a indasteri. Li-valve tsa serurubele tse nang le bophara bo boholo (9 ~ 750mm), khatello e phahameng (42.0mpa) le mocheso o pharalletseng (- 196 ~ 606 ℃) li hlahile, e leng se etsang hore mahlale a belofo ea serurubele a fihle boemong bo bocha.
Sephahla sa serurubele se na le khanyetso e nyane ea phallo ha se buloa ka botlalo. Ha lesoba le le pakeng tsa 15 ° le 70 ° le lona le ka laola phallo ka hloko. Ka hona, belofo ea serurubele e sebelisoa haholo tšimong ea taolo e kholo ea bophara.
Ha sesepa sa serurubele se sisinyeha ka ho hlakola, li-valve tse ngata tsa serurubele li ka sebelisoa ka likaroloana tse emisitsoeng tse mahareng. Ho ea ka matla a tiiso, e ka sebelisoa bakeng sa phofo le media oa granular.
Li-valve tsa serurubele li loketse taolo ea phallo.
