Chinangwa chekushandisa acheki vharafundiko kudzivirira kuyerera kwepakati, uye acheki vharafuinowanzoiswa panobuda pombi. Mukuwedzera, acheki vharafuyakaiswa panzvimbo yekubuda kwe compressor. Muchidimbu, kuitira kudzivirira reverse kuyerera kwepakati,cheki mavharuvhuinofanira kuiswa mumidziyo, midziyo kana mapaipi.
Kazhinji, vertical kusimudzacheki mavharuvhuanosarudzwa pamapaipi akachinjika ane dhayamita yezita re50mm. Kururamisa-kuburikidza nekusimudzacheki mavharuvhuinogona kuiswa pamitsetse yese yakachinjika uye yakatwasuka. Ivhavha yetsoka inowanzoiswa chete pamutsara wakatwasuka wepombi inopinza, uye yepakati inoyerera kubva pasi ichienda kumusoro.
Theswing check valveinogona kugadzirwa nepamusoro-soro yekushanda, PN kusvika ku42MPa, uye DN inogonawo kuva yakakura kwazvo, kusvika kudarika 2000mm. Zvichienderana nemidziyo yeimba uye zvisimbiso, chero yekushanda svikiro uye chero yekushanda tembiricha renji inogona kuiswa. Iyo yepakati imvura, chiutsi, gasi, corrosive medium, mafuta, chikafu, mushonga, etc. Kushanda tembiricha yepakati iri pakati -196~800°C.
Swing cheki mavharuvhuinogona kuiswa munzvimbo dzisingagumi uye inowanzoiswa pamitsetse yakatwasuka, asi inogonawo kuiswa pamitsetse yakatwasuka kana yakarerekera.
Thebutterfly cheki vharafuinokodzera kudzvinyirira kwakaderera uye dhayamita yakakura, uye mamiriro ekuisa ari mashoma. Nokuti kushanda kumanikidza kwebutterfly cheki vharafuhaigone kunge yakakwira zvakanyanya, asi iyo dhayamita yezita inogona kunge yakakura kwazvo, inogona kusvika kupfuura 2000mm, asi iyo yekumanikidza yezita iri pazasi 6.4MPa. Thebutterfly cheki vharafuinogona kugadzirwa kuita pair clamp type, iyo inowanzoiswa pakati pemaflange maviri epombi, uye inotora fomu yekubatanidza simbi yekubatanidza.
Thebutterfly cheki vharafuinogona kuiswa munzvimbo isina muganho uye inogona kuiswa pamutsetse wakachinjika, wakatwasuka kana wakarerekera.
Diaphragmcheki mavharuvhuakakodzera mapaipi anowanzoita nyundo yemvura, uye diaphragm inogona kunyatsobvisa sando yemvura kana yepakati ichiyerera ichipokana nekuyerera. Nekuti tembiricha yekushanda uye shandisa kudzvanywa kwe diaphragmcheki mavharuvhuakaganhurirwa nemidziyo yediaphragm, anowanzo shandiswa mukudzika-kudzvanywa kwakajairika tembiricha mapaipi, kunyanya akakodzera mapaipi emvura. Kazhinji, tembiricha yekushanda yepakati iri pakati -20 ~ 120 ° C, uye kushanda nesimba kuri <1.6MPa, asi diaphragm.cheki vharafuinogona kuwana yakakura caliber, uye iyo DN inogona kusvika kupfuura 2000mm.
Diaphragmcheki mavharuvhuyakashandiswa zvakanyanya mumakore achangopfuura nekuda kwekuita kwavo kwakanakisa kusapinda kwemvura, chimiro chiri nyore uye mutengo wakaderera wekugadzira.
Bhoracheki vharafunokuti chisimbiso ibhora rakafukidzwa nerabha, saka kuvharwa kwechisimbiso kwakanaka, kushanda kwakavimbika, uye kudzivirira kwekudengenyeka kwemvura kwakanaka; Uye nokuti chisimbiso chinogona kuva bhora rimwe chete, kana kuti rinogona kuitwa mabhora akawanda, saka rinogona kuitwa muhupamhi hukuru. Zvisinei, zvisimbiso zvaro zvisimbiso zvakakomba zvakaputirwa nerabha, izvo zvisingakodzeri mapaipi epamusoro-soro, akakodzera chete pakati nepakati-pasi-mapaipi.
Sezvo imba zvinhu bhoracheki vharafuinogona kugadzirwa nesimbi isina tsvina, uye bhora bhora rechisimbiso rinogona kuputirwa nePTFE engineering plastic, rinogona kushandiswawo mupombi ye general corrosive media.
Kupisa kwekushanda kwemhando iyi yevhavhavha yecheki iri pakati -101 ~ 150 ° C, kudzvinyirira kwayo kwezita ndeye ≤4.0MPa, uye dhiyabhorosi yezita iri pakati pe200 ~ 1200mm.
