Ama-valve e-pneumatic diaphragm angama-valve ezimboni ahlanganisa ukulawula okuzenzakalelayo namakhono aphuthumayo esandla, anezinzuzo eziyinhloko kanye nezimo zokusetshenziswa ezifanele kakhulu izimo zokusebenza ezinzima. Athembele ku-diaphragm ukuze ahlukanise ngokuphelele igumbi eliphakathi nendawo ekamelweni le-actuator, asuse ukuvuza kwangaphandle emthonjeni ngomklamo ongenabhokisi lokugcwala, ngenkathi futhi evikela izingxenye ezingaphezulu njengesiqu se-valve ekugqwaleni yi-medium, okwenza zibe zilungele izimo zokusebenza ezihilela imidiya enobuthi negqwala kakhulu. Njengoba inendlela yokugeleza ebushelelezi egcwele enikeza ukumelana nokugeleza okuphansi, usayizi we-DN40 unikeza amandla okugeleza aphezulu futhi awuvami ukuvaleka, okwenza ufaneleke kuma-media aqukethe izinhlayiya noma athambekele ekukhanyeni.

(isithombe: I-DN40 Pneumatic Diaphragm Valve)

Umzimba wevalvu ungafakwa ngepulasitiki noma wenziwe ngezinto ezingagqwali, futhi uhlanganiswe nama-diaphragm afana ne-EPDM noma i-PTFE, ungaphatha uketshezi olugqwala kakhulu njengezixazululo ze-acid-base, amanzi ahlanzekile, namanzi angcolile. Isondo elingaphezulu lesandla lenza kube lula ukuvula/ukuvala ngesandla kanye nokukhiya endaweni lapho kungekho khona umoya, futhi uma lihlanganiswa nomlawuli wokucindezela kwesihlungi ohlangothini, lisekela kokubili ukulawula okuzenzakalelayo okukude kanye nokusebenza okuphuthumayo ngaphansi kwezimo ezingalindelekile, kuhlangabezana nezidingo zokwenza okuzenzakalelayo kanye nokwephulwa kokuphepha. Njengoba inesakhiwo esilula, i-diaphragm kulula ukuyishintsha, inikeza imijikelezo yokushintsha efinyelela emashumini ezinkulungwane, ukusebenza okuzinzile, kanye nezindleko zokulungisa eziphansi.

Futhi zinezakhiwo ezinhle kakhulu zokulwa nokungcola kanye nezindawo ezilula ukuzihlanza. Indlela yokugeleza engenazo izindawo ezifile ivimbela insalela ephakathi nendawo, iqinisekisa ukusebenza okuzinzile kokuvala ngisho nangaphansi kwezimo ezivamile zokuqala, futhi ingazivumelanisa nezimo ezahlukahlukene zamapayipi okuhlanganisa ingcindezi enhle kanye nengcindezi encane engemihle.

Zisetshenziswa kabanzi ezimbonini ezifana namakhemikhali, ukuvikelwa kwemvelo, ukwelashwa kwamanzi, kanye nemithi: embonini yamakhemikhali, zisetshenziselwa ukuthutha uketshezi oluqothulayo njenge-hydrochloric acid kanye ne-lye; ekuphathweni kwamanzi angcolile ngokwemvelo, zifanelekela ukukhishwa kwendle kanye nokufakwa kwamakhemikhali okubandakanya udaka kanye nokungcola; izinhlobo zokuhlanzeka zezimboni zemithi nezokudla zihlangabezana nezidingo zoketshezi oluhlanzekile kanye nezinqubo ezihlanzekile. Zisetshenziswa futhi ekuthuthweni okuphakathi kwe-acid-base kanye nokulawulwa kwenqubo ezimbonini ezifana ne-metallurgy kanye nokukhiqizwa kwamandla, ikakhulukazi kumapayipi enqubo eqhubekayo noma eqhubekayo adinga ukuthembeka okuphezulu kokuvala kanye nokumelana nokugqwala, okwenza kube yisisombululo esingabizi kakhulu sezimo zokusebenza eziyinkimbinkimbi kanye nezimo ezikhethekile zemidiya.

I-Jinbin Valves ikhiqiza izinhlobo ezahlukene zamavalvu ngeminyaka engama-20 yesipiliyoni sokukhiqiza amavalvu. Uma unezidingo zamavalvu ezihlobene, sicela ushiye umlayezo ngezansi ukuze usithinte.
