Ivalve ye-diaphragm ithatha indawo yendibano ye-spool kunye nomzimba welinen-resistant-resistant kunye ne-diaphragm enganyangekiyo, esebenzisa intshukumo ye-diaphragm yokulawula. Isixhobo somzimba wevalve ye-diaphragm eyenziwe ngentsimbi etyhidiweyo, intsimbi etyhidiweyo, okanye intsimbi engatyiwayo, kwaye ifakwe kwiintlobo ngeentlobo zezinto ezikwaziyo ukubola okanye ukunxiba, irabha ye-diaphragm kunye ne-PTFE. I-diaphragm ye-lining inokumelana ne-corrosion eyomeleleyo, ekulungele ukulawulwa kwemithombo yeendaba ezomeleleyo ezifana ne-asidi eqinile kunye ne-alkali.
Ivalve ye-diaphragm inesakhiwo esilula, ukuxhathisa ulwelo oluncinci, umthamo wokuhamba mkhulu kunezinye iintlobo zeevalvu ezineenkcazo ezifanayo; Akukho kuvuza, kungasetyenziselwa ukulungiswa kwe-viscosity ephezulu kunye ne-particle medium suspended. I-diaphragm ihlukanisa i-medium ukusuka kwigumbi eliphezulu le-stem, ngoko ke akukho ndlela yokupakisha ayiyi kuvuza. Nangona kunjalo, ngenxa yemida ye-diaphragm kunye ne-lining materials, ukumelana noxinzelelo kunye nokumelana nobushushu akubi, ngokuqhelekileyo kufanelekile kuphela kwi-1.6MPa yoxinzelelo lwegama kunye ne-150 ℃ ngaphantsi.
Uphawu lokuhamba kwevalve ye-diaphragm isondele kwimpawu yokuvula ngokukhawuleza, ephantse ibe ngumgca phambi kwe-60% ye-stroke, kwaye izinga lokuhamba litshintshile kancinci emva kwe-60%. Iivalve ze-diaphragm ze-pneumatic nazo ziyakwazi ukuxhotyiswa ngezibonakaliso zempendulo, izixhobo ze-limiter kunye ne-positioner, ukwenzela ukuhlangabezana neemfuno zokulawula ngokuzenzekelayo, ulawulo lweprogram okanye ukulawulwa kokuhamba. Isignali yengxelo yevalufa ye-diaphragm yepneumatic usebenzisa itekhnoloji yoluvo lokungaqhagamshelwa. Imveliso isebenzisa ifilim propulsion cylinder, endaweni yepiston cylinder, ukuphelisa umsesane wepiston kulula ukuyonakalisa, okukhokelela ekuvuzeni kwaye awukwazi ukutyhala ukuvulwa kwevalve kunye nokuvala izinto ezingalunganga. Xa umthombo womoya usilela, usenako ukusebenzisa ivili lesandla ukuvula nokuvala ivalve.
