Polytetrafluoroethylene (PTFE), ngokuqhelekileyo eyaziwa ngegama layo elidumileyo le-EI DuPont yorhwebo i-polymer®, ikwafaneleka kakuhle ukucoca igumbi kunye nezicelo zamanzi adiyiweyo.Umzimba, isiqu, ibhola kunye namazibuko akhiwe kwi-PTFE.
Isicelo
Ukuvalwa okuqinileyo, i-PTFE-i-valve yebhola ye-PTFE yenkqubo yobunjineli kunye nezicelo zoshishino, ngokukodwa ezifanelekileyo kwimidiya ephazamisayo.
Ubungakanani begama: DN 15 ukuya kwi-DN 150Uxinzelelo lwegama: PN 10Amaqondo obushushu: −10 ukuya ku-200 °C
Iimbonakalo:
Ulwakhiwo lwe-PTFE lwemiphezulu emanzi yemithombo yeendaba.Ukusebenza okuthembekileyo kwetorque ephantsi.UkuJika kweKota ngePositive Stops.Uyilo luvumela indawo evulekileyo ngokungagqibelelanga yemitha yokuhamba ngemitha.Yonke imifuziselo inokufakwa kwiphaneli.Yonke imifuziselo ingasetyenziswa kubume bobushushu obuphezulu.
Inkcazo:
Umgaqo wokusebenza:
Inkqubo ephakathi inokuqukuqela ngodidi lwe-PTFE iValve yeBhola kulo naliphi na icala.Ibhola ene-cylindrical bore (itshaneli yebhola) ijikeleza kumbindi we-axis.I-angle ejikelezayo yebhola imisela izinga lokuhamba kwindawo ekhululekile phakathi komzimba kunye nomjelo webhola.I-shaft yebhola, ekhokelwa kwi-valve ye-valve, inokudibaniswa ngokuzikhethela kwi-actuator ye-pneumatic phezu kwe-adapter okanye ifakwe i-lever esebenza ngesandla.Ibhola itywinwe kumzimba ofakwe kwi-PTFE ngokusebenzisa amakhonkco ezihlalo ezinokutshintshiselwa.I-shaft yebhola itywinwe nge-packing-free, i-spring-loaded PTFE V-ring packing.
