Chimiro chediaphragm valveyakasiyana zvikuru neyemavharuvhu akajairika.Irwo rudzi rutsva rwevhavha uye fomu yakakosha yevhavha yekuvhara.Chikamu chayo chekuzarura nekuvhara ndicho diaphragm yakagadzirwa nenyoro Mukati wemukati wevhavha uye chikamu chekutyaira chakaparadzaniswa, uye ikozvino chinoshandiswa zvakanyanya muminda yakasiyana-siyana.Mavharuvhu e diaphragm anowanzo shandiswa anosanganisira mavharuvhu ane rabha-lined diaphragm, fluorine-lined diaphragm mavharuvhu, unlined diaphragm mavharuvhu, uye epurasitiki diaphragm mavharuvhu.
Diaphragm valve ine diaphragm inochinjika kana yakasanganiswa diaphragm mumuviri wevharuvhu uye chivharo chevharuvhu, uye chikamu chayo chekuvharira chishandiso chekumanikidza chakabatana nediaphragm.Chigaro chevharuvhu chinogona kuva weir mhando kana yakatwasuka-kuburikidza nemhando.
Kubatsira kwevhavhavhavha ye diaphragm ndeyokuti nzira yekushanda kwayo yakaparadzaniswa kubva kune nzira yepakati, iyo isingangogadziri kuchena kwekushanda kwekushanda, asi inodzivirirawo mukana wepakati mupombi inokanganisa zvikamu zvekushanda zvekushanda.Pamusoro pezvo, hapana chisimbiso chakaparadzana chechero rudzi chinodiwa pahunde, kunze kwekunge sechinhu chekuchengetedza mukutonga kwenhau dzine njodzi.
Mune diaphragm valve, sezvo svikiro rinoshanda rinongosangana nediaphragm uye muviri wevhavha, zvose zvinogona kushandisa zvakasiyana-siyana zvakasiyana-siyana, saka valve inogona kudzora zvakasiyana-siyana zvekushanda, kunyanya zvakakodzera kumakemikari ekuora kana. zvidimbu zvakaturikwa.pakati.
Kupisa kwekushanda kwevharuvhu ye diaphragm kunowanzo kuganhurirwa nemidziyo inoshandiswa kune diaphragm uye vharafu muviri lining, uye kushanda kwayo tembiricha siyana -50 kusvika 175 °C.Iyo diaphragm valve ine chimiro chakareruka uye inongoumbwa nezvikamu zvitatu zvikuru: muviri wevharuvhu, diaphragm uye musangano wevhavha yevhavha.Iyo valve iri nyore kuparadzanisa uye kugadzirisa nekukurumidza, uye kutsiva diaphragm kunogona kuitwa panzvimbo uye munguva pfupi.
Diaphragm valve zvinhu:

Kuchengeta Diaphragm Mavharuvhu
1. Usati waisa diaphragm valve, nyatsotarisa kana mamiriro ekushanda kwepombi ari maererano nehuwandu hunotsanangurwa hwekushandiswa kwevhavha, uye mukati memukati unofanirwa kucheneswa kudzivirira tsvina kubva pakunamatira kana kukuvadza zvikamu zvekuvhara.
2. Usapende pamusoro peiyo rubber lining layer uye rubber diaphragm nemafuta kudzivirira rubber kubva pakuzvimba uye kukanganisa hupenyu hwebasa revhavhavha yevhavha.
3. Ruoko rwemaoko kana nzira yekufambisa haibvumirwi kushandiswa pakusimudza, uye kudhumhana kunorambidzwa zvachose.
4. Paunenge uchishanda diaphragm valve manually, mubatsiri wemubatsiri haafaniri kushandiswa kudzivirira kukanganisa kwezvikamu zvekufambisa kana kuvhara zvikamu nekuda kwekunyanya kuwandisa.
5. Diaphragm valves inofanira kuchengetwa muimba yakaoma uye ine mhepo, uye stacking inorambidzwa zvachose.Magumo ese ari maviri e stock diaphragm valve anofanirwa kuvharwa, uye nzvimbo dzekuvhura nekuvhara dzinofanirwa kunge dzakavhurika zvishoma.
Gadzirisa zvikanganiso zvakajairika zve diaphragm mavharuvhu
1. Kushanda kwevhiri remaoko hakuchinjike: ①Dzinde revharuvhu rakakotama ②Tshinda yaparara ①Tvanza hunde yevharuvhu ②Bata shinda wowedzera mafuta.
2. Iyo pneumatic diaphragm valve haigone kuvhurika nekuvharika yega: ①Dhidhiyo yemhepo yakadzikira ②Simba rechirimo rakawandisa ③Rabha diaphragm yakuvadzwa ①Wedzera mhepo yekupa mhepo ②Deretsa simba rechirimo ③Tsinza diaphragm
3. Kudonha pakubatana pakati pemuviri wevharuvhu nebhoneti: ①Bhou rekubatanidza rakasununguka ②Rubber layer mumuviri wevharuvhu yatyoka ①Simbisa bhaudhi rekubatanidza ②Siva muviri wevharuvhu.
