Kuyera nemazvobutterfly valvesaizi yakakosha kuve nechokwadi chakakodzera uye kudzivirira kudonha. Nekuti mavharuvhu eshavishavi anoita basa rakakosha mumaindasitiri akasiyana. Kusanganisira mafuta uye gasi, zvidyarwa zvemakemikari uye masystem ekudzora kuyerera kwemvura. Aya mavharuvhu e butterfly anogadzirisa kuyerera kwemvura, kudzvanywa, midziyo yakasiyana uye inogadzirisa kuyerera kwemvura.
Kuziva kuyera saizi yevharuvhu ye butterfly kunogona kudzivirira kusashanda kwekuita uye kukanganisa kunodhura.
1. Butterfly valve basics
1.1 Chii chinonzi shavishavi vharuvhu? Shavishavi inoshanda sei?
Butterfly mavharuvhukudzora kufamba kwemvura mukati mepombi. Varuvhu yeshavishavi ine dhisiki rinotenderera rinobvumira mvura kuti ipfuure kana dhisiki ratendeuka rakafanana negwara rekuyerera. Kushandura disc perpendicular kune inoyerera nzira inomisa kuyerera.
1.2 Zvishandiso zvakajairika
Butterfly mavharuvhu anoshandiswa mumaindasitiri akasiyana siyana, anosanganisira oiri negesi, zvidyarwa zvemakemikari uye masisitimu ekudzora kuyerera kwemvura. Ivo vanodzora kuyerera kweyero, midziyo yakasiyana uye inogadzirisa kuyerera kwemvura. Kuita kwavo kwakasiyana-siyana kunoita kuti vakwane pakati, pasi, tembiricha yepamusoro uye masevhisi ekumanikidza.
2. Unoyera Sei Butterfly Valve?
2.1 Saizi yechiso nechiso
Saizi yakatarisana (face-to-face size) zvinoreva nhambwe iri pakati pezviso zviviri zvevharuvhu yeshavishavi kana yaiswa mupombi, kureva kuti, nhambwe pakati pezvikamu zviviri zvemafurange. Chiyero ichi chinovimbisa kuti butterfly valve yakaiswa zvakanaka mupombi system. Hurukuro hwakatarisana nechiso hunogona kuchengetedza kutendeseka kwehurongwa uye kudzivirira kudonha. Ukuwo, zvimiro zvisina kururama zvinogona kutungamirira kune ngozi dzekuchengeteka.
Anenge ese mwero anotsanangura kutarisana-ne-chiso kuyera kwemavharuvhu e butterfly. Inonyanya kugamuchirwa ndeye ASME B16.10, iyo inotsanangura zviyero zvemarudzi akasiyana-siyana evhavhavhavha, kusanganisira butterfly valves. Kuomerera kune izvi zviyero kunovimbisa kuenderana nezvimwe zvikamu muhurongwa huripo hwemutengi.
2.2 Kudzvanywa chiyero
Kutsikirirwa kwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhahunoratidza kumanikidzika kukuru uko vharuvhu yeshavishavi inogona kumira nayo ichishanda zvisina njodzi. Kana chiyero chekumanikidza chisina kunaka, vheji yevhavhavha yepasi-yakaderera inogona kukundikana pasi pemamiriro epamusoro-soro, zvichikonzera kukanganisa kwehurongwa kana kunyange njodzi dzekuchengeteka.
Butterfly mavharuvhu anowanikwa mumhando dzakasiyana dzekudzvanyirira, ayo anowanzo kubva kuKirasi 150 kusvika Kirasi 600 (150lb-600lb) zvinoenderana neASME zviyero. Mamwe mavharuvhu eshavishavi anokwanisa kumirisana nePN800 kana kutopfuura. Sarudza iyo system pressure inoenderana nezvinodiwa zvekushandisa. Kusarudza iyo chaiyo yekumanikidza chiyero kunovimbisa kuita kwakanakisa uye hupenyu hwebasa hwevhavhavhavhavhavha.
3. Butterfly vharafu zita dhayamita (DN)
Iyo inonzi dhayamita yevhavhavhavhavha inowirirana nedhayamita yepombi yainobatanidza. Kurongeka kwemavharuvhu evharuvhu kwakakosha kudzikisa kurasikirwa kwekumanikidza uye kushanda zvakanaka kwehurongwa. Ivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha inogona kukonzera kuyerera kwemvura kana kudonha kwakanyanya,zvinokanganisa kushanda kwehurongwa hwese.
Zviyero zvakaita seASME B16.34 zvinopa gwara rekuyera vharuvhu, kuve nechokwadi chekuenderana uye kuenderana pakati pezvikamu mukati mehurongwa. Miyero iyi inobatsira kusarudza saizi yevharuvhu yeshavishavi yakakodzera kune imwe application.
4. Kuyera Seat Size
Thebutterfly valve seatsaizi inosarudza kukwana kwakakodzera uye kushanda kwevharuvhu yeshavishavi. Kuyera kwakaringana kunovimbisa kuti chigaro chinokodzera muviri wevharuvhu. Kukwana uku kunodzivirira kudonha uye kunochengetedza kutendeseka kwehurongwa.
4.1 Kuyera Maitiro
4.1.1. Yera dhayamita yegomba rinokwirisa (HS): Isa caliper mugomba uye kuyera dhayamita nemazvo.
4.1.2. Sarudza urefu hwechigaro (TH): Isa tepi chiyero pazasi pechigaro. Eresa wakatwasuka kusvika kumucheto wepamusoro.
4.1.3. Pima ukobvu hwechigaro (CS): Shandisa caliper kuyera ukobvu hwechikamu chimwe chete kumucheto kwechigaro.
4.1.4. Yera dhayamita yemukati (ID) yechigaro chevharuvhu: Bata micrometer pamutsara wepakati pechigaro chevharuvhu.
4.1.5. Sarudza kunze kwedhayamita (OD) yechigaro chevhavha: Isa caliper pamucheto wekunze wechigaro chevhavha. Tambanudza kuyera dhayamita rekunze.
5. Kuparara kwakadzama kwezviyero zvevharuvhu yeshavishavi
5.1 Kureba kwevharuvhu A
Kuti uyere hurefu A, isa caliper kana tepi kuyerwa panotangira chivharo chevharuvhu yeshavishavi woyera kusvika pamusoro pehunde yevharuvhu. Iva nechokwadi chokuti kuyerwa kunovhara hurefu hwose kubva pakutanga kwemuviri wevharuvhu kusvika kumagumo evharuvhu. Iyi dimension yakakosha pakuona hukuru hwesevhavhavhavharuvhu uye inopawo chirevo chekuchengetedza nzvimbo yevhavhavhavhavha muhurongwa.
5.2 Valve plate dhayamita B
Kuyera dhayamita yeplate yevharuvhu B, shandisa caliper kuyera chinhambwe kubva kumucheto kweplate yevharuvhu, uchiteerera kupfuura nepakati peplate yevharuvhu. Yakanyanya kudiki inodonha, yakawandisa inowedzera torque.
5.3 Ukobvu hwemuviri wevhavha C
Kuyera kukora kwevharuvhu C, shandisa caliper kuyera chinhambwe pamutumbi wevharuvhu. Kuyera kwakaringana kunovimbisa kukwana kwakakodzera uye kushanda mupombi system.
5.5 Kiyi Hurefu F
Isa caliper pamwe nekureba kwekiyi kuyera kureba F. Iyi dimension yakakosha kuti ive nechokwadi chekuti kiyi inoenderana nemazvo kune butterfly valve actuator.
5.5 Stem Diameter (Kureba kwedivi) H
Shandisa caliper kunyatsoyera dhayamita yehunde. Kuyera uku kwakakosha kuitira kuti dzinde rikwane zvakanaka mukati megungano revharuvhu yeshavishavi.
5.6 Gomba Saizi J
Edza kureba J nekuisa caliper mukati megomba nekuipfuudza kune rimwe divi. Kunyatsoyera kureba J kunogonesa kuenderana nezvimwe zvikamu.
5.7 Thread Saizi K
Kuyera K, shandisa geji yeshinda kuti uone saizi chaiyo yeshinda. Kunyatsoyera K kunovimbisa kusungirirwa kwakakodzera uye kubatana kwakachengeteka.
5.8 Nhamba yeMakomba L
Verenga huwandu hwemaburi pavharuvhu flange. Chiyero ichi chakakosha kuti vharavhavhavha yeshavishavi inogona kuvharirwa zvakachengeteka kune pombi system.
5.9 Control Center Distance PCD
PCD inomiririra dhayamita kubva pakati pegomba rekubatanidza nepakati peplate yevharuvhu kusvika kune diagonal gomba. Isa caliper pakati pegomba regugi uye uwedzere kusvika pakati pegomba diagonal kuyera. Kuyera chaiko kuyera P kunovimbisa kurongeka kwakaringana uye kuiswa muhurongwa.
6. Mazano Anoshanda uye Mafungiro
6.1. Kurongeka kwezvishandiso zvisina kurongeka: Ita shuwa kuti ese maturusi ekuyeresa akakwenenzverwa. Zvishandiso zvisina kururama zvinogona kutungamirira kune zviyero zvisina kururama.
6.2. Kusarongeka panguva yekuyera: Kusarongeka kunogona kutungamirira kukuverenga kusina kururama.
6.3. Kuregeredza tembiricha mhedzisiro: Account yekuchinja kwekushisa. Simbi uye zvikamu zverabha zvinogona kuwedzera kana chibvumirano, zvichikanganisa kuyerwa kwemhedzisiro.
Kuyera nemazvo zvigaro zvevharuvhu zvinoda kutarisisa zvakadzama uye kushandisa maturusi akakodzera. Kutevera matanho aya kunovimbisa kuti butterfly valve yakanyatsoiswa uye inoshanda zvakanaka mukati mehurongwa.
7. Mhedziso
Kuyera nemazvo chiyero chevharuvhu yeshavivha inovimbisa kuita kwakaringana uye kuvimbika kwehurongwa. Shandisa maturusi akaremerwa pakuyera chaiko. Rongedza maturusi nemazvo kudzivirira kukanganisa. Funga nezvemigumisiro yekushisa pane zvikamu zvesimbi. Tsvaka mazano enyanzvi pazvinenge zvakakodzera. Kuyera kwakarurama kunodzivirira matambudziko ekushanda uye kuvandudza kushanda kwehurongwa.
