Kupatsanura uye nzira yekuisa mavharuvhu ekutarisa
Pfupiso yevharuvhu yekutarisa
Mavharuvhu ekuongorora mudziyo unokosha wekudzora mvura, unoshandiswa zvakanyanya mumapurojekiti ekuchengetedza mvura, petrochemicals, kuchengetedzwa kwezvakatipoteredza nedzimwe nzvimbo. Basa rayo guru nderekudzivirira kudzokera shure kwemidziyo yemagetsi uye kuona kuti nzira imwe chete yemidziyo yemagetsi inoyerera muhurongwa hwemapaipi. Kurongeka uye nzira yekuisa mavharuvhu ekuongorora zvinokanganisa mashandiro avo uye hupenyu hwavo hwebasa. Chinyorwa chino chichatsanangura mhando dzakasiyana dzemavharuvhu ekuongorora uye zvaunofanira kufunga nezvazvo pamirayiridzo yekuisa kwawo zvakadzama.
Mhando huru dzemavharuvhu ekutarisa
Zvichienderana nechimiro uye musimboti wekushanda, mavharuvhu ekutarisa anonyanya kukamurwa kuita mhando dzinotevera:
1. Vharuvhu yekutarisa ndiro mbiri
2. Vharuvhu yekutarisa chikwidzo
3. Vharuvhu yekutarisa bhora
4. Vharuvhu yekutarisa yekutenderera
Nzira yekuisa vheji yekutarisa
1. Kuiswa kwakarara: zvinoreva nzira yekuisa check valve papombi yakataramuka, iyo inowanzoshandiswa mumasystem emapombi ane pressure yakaderera, uye dhayamita yevharuvhu yakakura kupfuura dhayamita yepombi.
2. Kuiswa kwakamira: zvinoreva nzira yekuisa check valve papombi yakamira, iyo inowanzoshandiswa mumasystem emapaipi ane simba rakawanda, uye dhayamita yevharuvhu diki pane dhayamita yepombi.
1. Vharuvhu yekutarisa madhisiki maviri
Vharuvhu yekutarisa madhisiki maviri: kazhinji kacho ine madhisiki maviri e semicircular anotenderera tsinde rakanangana nepakati pekuyerera kwemvura. Mavharuvhu ekuongorora madhisiki maviri madiki ane hurefu hudiki. Anoiswa pakati pemaflange maviri. Anowanzo sungirirwa kana kuputirwa. Anowanzo shandiswa mumapaipi ane dhayamita ye ≤1200mm.
Nzira yekuisa vharuvhu yekutarisa dhisiki mbiri
Mavharuvhu ekuongorora madhisiki maviri anogona kuiswa akatwasuka kana kuti akatwasuka mupaipi. Kuisa kwakatwasuka kunogona kuita kuti kuvhurwa nekuvharwa kwevharuvhu rekuongorora kukanganisike negiravhiti, zvichiita kuti kumhanya kwekuvhura kwayo kuve kwakasimba uye kuderedza kurasikirwa nekumanikidzwa kwepaipi zvinobudirira. Kuisa kwakatwasuka kunogona kuita kuti vharuvhu rikanganisike negiravhiti kana ravharwa, zvichiita kuti chisimbiso charo chive chakasimba. Pamusoro pezvo, kuisa kwakatwasuka kunogona kudzivirira dhisiki revharuvhu rekuongorora kuti risadengenyeke nekukurumidza panguva yekuchinja kwemvura nekukurumidza, kuderedza kupera kwedhisiki nechigaro chevharuvhu, uye kuwedzera hupenyu hwebasa revharuvhu.
2. Vharuvhu yekutarisa kutenderera
Mavharuvhu ekuongorora kutendereraIva nedhisiki revharuvhu. Kana dhisiki revharuvhu richiyerera mberi, dhisiki revharuvhu rinosundirwa rakavhurika; kana dhisiki revharuvhu richiyerera nenzira yekumashure, dhisiki revharuvhu rinodzoserwa pachigaro chevharuvhu kudzivirira kudzokera shure. Rudzi urwu rwevharuvhu runowanzo shandiswa mumapaipi makuru nekuda kwechimiro chayo chiri nyore uye kusadzivirira kwaro.
Nzira yekuisa Swing check valve
Mavharuvhu ekutarisa maswingi anogona kuiswa akatwasuka kana kuti akatwasuka, asi zvinowanzokurudzirwa kuti aiswe mumapaipi akatwasuka. Zvinofanira kucherechedzwa kuti, zvichienderana nemamiriro chaiwo, vharuvhu rekutarisa maswingi rinogonawo kuiswa rakatwasuka, chero bedzi kona yekuisa isingapfuure madhigirii makumi mana nemashanu uye nzvimbo yekuisa yakakodzera, hazvizokanganisi mashandiro enguva dzose ekuvhura nekuvhara kwevharuvhu.
3. Vharuvhu yekuyedza kusimudza yakarara
Dhisiki yevharuvhu yevharuvhu yekusimudza yakatambanudzwa inokwira nekudzika ichitevedza gwara rekutungamira riri mumuviri wevharuvhu. Kana dhisiki yevharuvhu ichiyerera mberi, dhisiki yevharuvhu inosimudzwa; kana dhisiki yevharuvhu ichiyerera ichienda kune rimwe divi, dhisiki yevharuvhu inodzokera kuchigaro chevharuvhu kudzivirira kudzokera shure.
Kutungamira kwekuisa kwevharuvhu yekusimudza yakatsetseka
Vharuvhu yekusimudza yakatambanudzwa inofanira kuiswa papombi yakatambanudzwa. Nekuti kana yaiswa yakatwasuka, vharuvhu yayo iri muchimiro chakatambanudzwa, kushanda kwayo pakati nechigaro chevharuvhu kunoderera nekuda kwehuremu hwayo, zvichikanganisa kushanda kwevharuvhu.
4. Vharuvhu yekuyedza kusimudza yakatwasuka
Yekumiramavharuvhu ekuongorora kusimudza, gwara rekufamba kwepakati pevharuvhu rakafanana negwara repaipi. Uye pakati pepakati pevharuvhu panoenderana nepakati penzira yekuyerera kwemvura.
Kutungamira kwekuisa kweVertical lift check valve
Mavharuvhu ekutarisa akamiswa anofanira kuiswa akamira mumapaipi uko medium inoyerera ichikwira, nekuti simba rinokwevera pasi rinobatsira kuti vharuvhu ivhare nekukurumidza kana kuyerera kwamira.
5. Vharuvhu yekutarisa bhora
Vharuvhu yekutarisa bhora inoshandisa bhora rinofamba richikwira nekudzika mumuviri wevharuvhu. Kana bhora richiyerera mberi, bhora rinosundirwa kure nechigaro chevharuvhu, mugero unovhurika, uye bhora rinopfuura; kana bhora richiyerera nenzira yekumashure, bhora rinodzokera kuchigaro chevharuvhu kudzivirira kudzokera shure.
Kutungamira kwekuisa kwevharuvhu yekutarisa bhora
Mavharuvhu ekuongorora bhora anogona kuiswa pamapombi akatambanuka, asi anonyanya kukodzera kuiswa akamira, kunyanya kana medium ichiyerera ichikwira. Kurema kwebhora kunobatsira kuvhara vharuvhu kana mvura yamira.
Zvinhu zvinokanganisa kuiswa kwevharuvhu yekuyedza yakamira
Pakuisa vharuvhu yekutarisa yakatwasuka, zvinhu zvinoverengeka zvinofanirwa kutariswa kuti ive nechokwadi chekuti inoshanda zvakanaka:
1. Kuyerera kwemvura
Pakuisa divi rakamira, nzira yekuyerera kwechinhu ichi inokosha. Pakuyerera kumusoro, dhisiki revharuvhu rinogona kuvhurwa nekumanikidzwa kwechinhu ichi, uye kuvhara ndiko kunobatsira dhisiki revharuvhu kudzokera panzvimbo yaro, nepo pakuyerera pasi, matanho ekuwedzera angadikanwa kuti vharuvhu ivhare zvakavimbika.
2. Simba regiravhiti
Simba rekukwevera pasi rinokanganisa kuvhurwa nekuvharwa kwevharuvhu. Mavharuvhu anovimba negiravhiti kuti avhare, akadai semavharuvhu ekuongorora mapurasitiki maviri uye anosimudza, anoshanda zviri nani kana achiyerera akamira kumusoro.
3. Hunhu hweMidhiya
Hunhu hwemidziyo yemagetsi, yakadai sekusimba, kuwanda, uye huwandu hwemidziyo yemagetsi, hunokanganisa mashandiro evharuvhu. Mitambo yemagetsi ine michina yemagetsi kana yemagetsi inogona kuda dhizaini yakasimba uye kugadziriswa nguva nenguva kuti ive nechokwadi chekuti vharuvhu inoshanda zvakanaka.
4. Nzvimbo yekuisa
Nzvimbo yekuisa, kusanganisira tembiricha, kumanikidzwa, uye kuvapo kwezvinhu zvinoparadza, zvinokanganisa mashandiro uye hupenyu hwevharuvhu. Kusarudza zvinhu nemagadzirirwo akakodzera nzvimbo chaiyo kunogona kuwedzera hupenyu hwevharuvhu.
Mabhenefiti ekuiswa kwakamira cheki vharuvhu
1. Kushandiswa kwegiravhiti
Kana divi remagetsi richikwira, simba rinokwevera pasi rinobatsira vharuvhu kuti ivhare, rinovandudza mashandiro ekuvhara, uye haridi rubatsiro rwekunze.
2. Deredza kupfeka
Kushandisa simba rekukweva remagetsi nevharuvhu kuvhara vharuvhu rekutarisa kunogona kuderedza kudedera, kuderedza kupera simba, kuwedzera hupenyu hwevharuvhu, uye kuderedza kuwanda kwekugadzirisa.
Zvakaipa zvekuiswa kwemadzirocheki vharuvhu
1. Kudzivirira kuyerera kwemvura
Kuisa vertical kunogona kuwedzera resistance yekuyerera kwemvura, kunyanya kuma vertical lift check valves, ayo anofanirwa kuramba kwete huremu hwe valve plate chete, asiwo kumanikidzwa kunobva muchitubu chiri pamusoro pe valve plate. Izvi zvichaita kuti kuyerera kwemvura kuderere uye kushandiswa kwesimba kwakawedzerwa.
2. Chinhu chenyundo yemvura
Kana chinhu ichi chikayerera mudenga, simba revharuvhu rekutarisa uye simba remuchina wacho zvinowedzera kumanikidzwa mupaipi, zvichiita kuti zvive nyore kukonzera dambudziko remvura.
