Ubume beivalve ye-diaphragmyahluke kakhulu kuleyo yeevalvu eziqhelekileyo.Luhlobo olutsha lwevalve kunye nefom ekhethekileyo yevalve yokuvala.Inxalenye yayo yokuvula kunye nokuvala i-diaphragm eyenziwe nge-soft I-cavity yangaphakathi yekhava kunye nenxalenye yokuqhuba iyahlukana, kwaye ngoku isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo.Izivalo zediaphragm ezisetyenziswa ngokuqhelekileyo ziquka iivalvu zediaphragm ezinerabha, ivalve ene-fluorine-lined diaphragm, iivalvu zediaphragm ezingafakwanga mgca, kunye neplastiki ye-diaphragm valves.
Ivalve ye-diaphragm ixhotyiswe nge-diaphragm eguquguqukayo okanye i-diaphragm edibeneyo kumzimba wevalve kunye nesivalo sevalvu, kwaye indawo yayo yokuvala sisixhobo sokucinezela esidityaniswe ne-diaphragm.Isihlalo sevalve sinokuba luhlobo lwe-weir okanye uhlobo oluthe ngqo.
Inzuzo ye-valve ye-diaphragm kukuba indlela yokusebenza kwayo ihlukaniswe ukusuka kwinqanaba eliphakathi, elingaqinisekisi kuphela ukucoceka kwendawo yokusebenza, kodwa iphinde ithintele ukuba kungenzeka ukuba i-medium kwipayipi ichaphazele iindawo zokusebenza zendlela yokusebenza.Ukongezelela, akukho sitywina esahlukileyo salo naluphi na uhlobo olufunekayo kwisiqu, ngaphandle njengendawo yokhuseleko kulawulo lweendaba eziyingozi.
Kwivalve ye-diaphragm, kuba indawo esebenzayo inxibelelana kuphela ne-diaphragm kunye nomzimba wevalvu, zombini ezinokusebenzisa izinto ezahlukeneyo ezahlukeneyo, ngoko ke ivalve inokulawula ngokufanelekileyo iintlobo ngeentlobo zemithombo yeendaba esebenzayo, ngakumbi ilungele ukugqwala kweekhemikhali okanye amasuntswana amisiweyo.phakathi.
Ubushushu bokusebenza kwevalve ye-diaphragm budla ngokukhawulwa zizinto ezisetyenziselwa i-diaphragm kunye nevalve yomzimba we-valve, kwaye ubushushu bokusebenza kwayo bumalunga -50 ukuya kwi-175 °C.Ivalve ye-diaphragm inesakhiwo esilula kwaye yenziwe ngamalungu amathathu kuphela: i-valve body, i-diaphragm kunye nendibano yesigqubuthelo sevalve.I-valve ilula ukuchithwa kunye nokulungiswa ngokukhawuleza, kwaye ukutshintshwa kwe-diaphragm kungenziwa kwisayithi kunye nexesha elifutshane.
Imathiriyeli yevalvu ye-diaphragm:

Ukugcina iiValufa zeDiaphragm
1. Ngaphambi kokufaka i-valve ye-diaphragm, jonga ngokucophelela ukuba iimeko zokusebenza zombhobho zihambelana noluhlu oluchaziweyo lokusetyenziswa kwe-valve, kwaye i-valve yangaphakathi kufuneka ihlanjululwe ukukhusela ukungcola ekubambeni okanye ukulimaza iindawo zokutywinwa.
2. Musa ukupeyinta ubuso bomgca werabha kunye ne-rubber diaphragm ngegrisi ukukhusela i-rubber ekudumbeni kwaye ichaphazele ubomi benkonzo yevalve ye-diaphragm.
3. Isondo lesandla okanye indlela yokuhambisa ayivumelekanga ukuba isetyenziselwe ukuphakamisa, kwaye ukungqubana kunqatshelwe ngokungqongqo.
4. Xa usebenzisa i-valve ye-diaphragm ngesandla, i-lever encedisayo ayifanele isetyenziswe ukukhusela umonakalo kwiindawo zokuqhuba okanye ukutywina ngenxa ye-torque eninzi.
5. Iivalve ze-diaphragm kufuneka zigcinwe kwigumbi elomileyo kunye nelomoya, kwaye ukupakisha kunqatshelwe ngokungqongqo.Zombini iziphelo zesivalo se-diaphragm kufuneka zitywinwe, kwaye iindawo zokuvula kunye nokuvala kufuneka zibekwimeko evuleke kancinane.
Sombulula iimpazamo eziqhelekileyo zeevalvu ze-diaphragm
1. Ukusebenza kwevili lesandla akuguquguquki: ①Isiqu sevalve igobile ②Intambo yonakele ①Buyisela isiqu sevalve ②Nyanga intambo kwaye wongeze i-lubricant.
2. Ivalve ye-pneumatic diaphragm ayinakuvuleka kwaye ivale ngokuzenzekelayo: ①Uxinzelelo lomoya luphantsi kakhulu ②Amandla asentwasahlobo mkhulu kakhulu ③Irabha diaphragm yonakele ①Yandisa uxinzelelo lonikezelo lomoya ②Nciphisa amandla asentwasahlobo ③Buyisela i-diaphragm
3. Ukuvuza kuqhagamshelo phakathi komzimba wevalvu kunye nebhonethi: ①Ibholithi yokudibanisa ikhululekile ② Umaleko werabha kumzimba wevalvu wophukile ①Qinisa ibholithi yokudibanisa ②Buyisela indawo yesivalo sevalvu.
