Butterfly mavharuvhudziri kwese kwese mumaindasitiri ekushandisa uye chinhu chakakosha pakudzora kuyerera kwemvura dzakasiyana mumapaipi.Chinonyanya kutariswa pakusarudza uye kushandisa shavishavi vharuvhu ndiyo yakanyanya kudzvinyirira chiyero.Kunzwisisa chiyero ichi kwakakosha pakuita kuti ive yakachengeteka uye inobudirira kushanda kwemvura masisitimu.
Muchinyorwa chino, isu tichanyura mune iyo pfungwa yekunyanya kudzvanywa ratinga iyo butterfly valve inogona kumira, uye kudzidza maitiro eiyo yakatemerwa kudzvanywa kubva kuzvinhu zvakaita se butterfly valve dhizaini, zvinhu, kuiswa chisimbiso, nezvimwe.
Ndeipi yakanyanya kumanikidza?
Kunyanya kudzvanywa kwevharuvhu yeshavishavi kunoreva kumanikidzwa kukuru uko vharuvhu yeshavishavi inogona kushanda zvisina njodzi pasina kutadza kushanda kana kukanganisa kushanda.Izvi zvinotevera zvinhu zvakati kuti zvinotarisa huwandu hwekumanikidza kwevhavhavhavhavhavhavha
1. Butterfly valve zvinhu
Zvishandiso zvinoshandiswa kugadzira muviri wevharuvhu, ndiro yevharuvhu, dzinde revharuvhu uye chigaro chevharuvhu ndizvo zvinhu zvekutanga pakuona kudzvanywa kwevhavhavhavhavhavha.Zvishandiso zvine simba rakanyanya kusimba, corrosion resistance uye kugadzikana kwetembiricha zvinogona kumirisana nedzvinyiriro huru.Semuyenzaniso, simbi isina tsvina mavharuvhu eshavishavi anogona kumirisana nepamusoro-soro nekuda kwekushomeka kwawo kwegora uye simba.
Thechigaro chevharuvhuzvekuisa chisimbisozvichakanganisawo simba rinotakura simba revhavhavhavhavha.Semuyenzaniso, EPDM, NBR, nezvimwewo zvinowanzoshandiswa rubber sealing materials, asi simba radzo rekutakura dzvinyiriro ishoma.Kune maapplication anodiwa kuti amire kudzvinyirirwa kwepamusoro, zvimwe zvakanyanya kumanikidza-resistant chisimbiso zvinhu zvinogona kusarudzwa.
2. Butterfly valve structure
Chimiro chevhavhavhavhavha ndechimwe chinhu chakakosha chinokanganisa kumanikidzwa kwevhavhavhavhavha.Semuenzaniso, iyo yepakati-yakapfava-kuvharisa butterfly valve inowanzoshandiswa mune yakaderera-kudzvanywa masisitimu, anoti PN6-PN25.Iyo double-eccentric butterfly valve dhizaini inonatsiridza kushanda kwekuvharisa nekushandura chimiro cheshavishavi ndiro uye chigaro chevharuvhu kuti zvimire kumanikidzwa kukuru.
3. Butterfly vharafu muviri rusvingo ukobvu
Pane hukama hwakaenzana pakati pehukuru hwevhavha yemuviri rusvingo ukobvu uye kudzvanywa.Kazhinji iyo yakakura chiyero chekumanikidza kwevharuvhu, kukora kwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavande masimba anoitwa kana mvura ikawedzera.
4. Butterfly valve pressure design standards
Magadzirirwo emagadzirirwo evharuvhu yeshavishavi anozotaura kumanikidzwa kukuru kwainokwanisa kutsungirira.Butterfly mavharuvhu anogadzirwa achitevedzera API (American Petroleum Institute), ASME (American Society of Mechanical Engineers), ISO (International Organisation for Standardization) uye mamwe mazinga eindasitiri, uye anoongororwa zvakanyanya uye kuongororwa kuti ave nechokwadi chekuti vharafu yeshavi inosangana nezvakatsanangurwa. pressure level.
Mavharuvhu eButterfly Akanaka Kune Kudzvinyirirwa Kwepamusoro?
Butterfly mavharuvhu anogona kupatsanurwa kuva vacuum butterfly mavharuvhu, yakaderera-kumanikidzwa butterfly mavharuvhu, yepakati-kumanikidzwa shavishavi mavharuvhu, uye mukuru-kumanikidzwa shavishavi mavharuvhu maererano nezita kumanikidzwa.
1).Vacuum butterfly valve—vharuvhu yeshavishavi ine simba rekushanda rakaderera pane rakajairwa mumhepo.
2).Low pressure butterflyvharafu-vharuvhu yeshavishavi ine dzvinyiriro yezita PN isingasviki 1.6MPa.
3).Ivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavharuvhuvhuvhuruvhuvhuvhuvhurukumanikidzazita PN 2.5~6.4MPa.
4).High-pressure butterfly valve-butterfly valve ine zita rekumanikidza PN10.0 ~ 80.0MPa.
Kunyanya kudzvanywa kwevharuvhu yeshavishavi kwakangofanana nepureti pfupi yemugomo.Kuwanda kwemvura kunoenderana nendiro pfupi.Izvo zvakafanana ndezvechokwadi kune yakanyanya kudzvinyirira kukosha kwevhavhavhavhavhavha.
Saka isu tinoona sei iyo yakanyanya kudzvanywa rating?
Nzira yekuona kuti vharuvhu yeshavishavi ndiyo yakanyanya kudzvanyirira chiyero chekumanikidza kwevharuvhu kutevedzana kwemiedzo inoitwa nemugadziri kuti aongorore kushanda kwevharuvhu uye kuona kudzvanywa kwayo.Miedzo iyi inogona kusanganisira:
1. Kuongorora zvinhu
Ita ongororo yemetallographic pazvikamu zvevhavhavhavha kuti uone zvivakwa zvezvinhu, uye ita bvunzo dzemakanika kuona kuti butterfly valve inosangana nemiyero yakatemwa yesimba, ductility, nezvimwe.
2. Kuongororwa kweHydrostatic
Ivhavha inoiswa pasi pekumanikidzwa kwemvura yakawandisa kupfuura yakanyanya kuyerwa kudzvanywa (kazhinji pane ambient kana tembiricha yakakwira) kuti iongorore kutendeseka kwayo kwechimiro uye chisimbiso kuita.
1).Kugadzirira kusati kwaedzwa
Usati waitisa butterfly valve hydraulic test, gadziriro dzinotevera dzinoda kuitwa:
a)Tarisa kuvimbika kwemidziyo yekuyedza kuona kuti bvunzo inogona kuitwa zvakachengeteka uye zvakajairwa.
b)Ita shuwa kuti vharuvhu yeshavishavi yakaiswa zvakanaka uye kubatana nemushini wekuyeresa wakanyatsovharwa.
c)Sarudza pombi yemvura ine dzvinyiriro yakakodzera kuti uve nechokwadi chekuti muedzo wekumanikidza uye mwero wekuyerera zvinosangana nezvinodiwa.
d)Bvisa marara anogona kukanganisa mhinduro dzebvunzo panguva yebvunzo uye ona kuti nharaunda yebvunzo yakachena uye yakatsvinda.
2).Matanho ekuedza
a)Tanga wavhara vharafu pavhavhavhavhavha, wozovhura pombi yemvura, uye zvishoma nezvishoma wedzera dzvinyiriro yemvura kuti isvike pakuedza.
b)Chengetedza kudzvanywa kwekuyedza kwenguva uye tarisa kana paine kuvuza kwakatenderedza vharuvhu yeshavishavi.Kana pane kuputika, inofanirwa kugadziriswa nenguva.
c)Mushure menguva yekuyedzwa, zvishoma nezvishoma deredza kudzvinyirirwa kwemvura uye uchenese vharuvhu ye butterfly uye yekuyeresa yekuyeresa muchina kudzivirira kusvibiswa kwemvura mushure mebvunzo.
3).Nzira dzekuedza
Kune kunyanya dzinotevera nzira dze butterfly valve hydraulic test:
a)Static pressure test method: Misa pombi yemvura, chengetedza kudzvanywa kwemaawa 1-2, uye tarisa kana paine kuvuza kwakatenderedza vharuvhu yeshavishavi.
b)Dynamic pressure test method: Paunenge uchichengetedza bvunzo kuyerera uye kudzvanywa, vhura shavishavi vharuvhu, tarisa kana vharuvhu ichishanda zvakanaka, uye tarisa kana paine kuvuza kwakaitenderedza.
c)Air pressure test: Isa mhepo kana gasi kudzvanya kuvharuvhu yeshavishavi kuti utevedzere mamiriro ekushanda uye uongorore mapinduriro ayo pakuchinja-chinja kwekumanikidza kuti uve nechokwadi chekuita kwakavimbika pasi pemamiriro ekuchinja.
d)Cycling test: The butterfly valve inodzokororwa kutenderera pakati penzvimbo dzakazaruka uye dzakavharwa pasi pemamiriro akasiyana-siyana ekumanikidzika kuti iongorore kusimba kwayo uye kuvhara kuvimbika.
Sei uchisarudza iyo yakanyanya kudzvinyirira chiyero chevhavhavhavhavha?
Kusarudza iyo yakanyanya kudzvinyirira chiyero inokubvumira kuti usarudze yakakodzera butterfly valve yekushandisa uye inovimbisa kushanda kwakachengeteka mukati meiyo yakatarwa yekumanikidza miganho.
1. Kuenderana Kwekushandisa
Sarudza shavishavi vharuvhu ine pressure rating inodarika iyo yakanyanya kumanikidza yekushandisa inogona kuitika mupiping system kudzivirira kuwandisa kwevhavhavhavhavhavha.
2. Kufunga nezvetembiricha
Funga nezvekuchinja kwekushisa muhurongwa hwemvura, kwete chete nekuda kwekuwedzera kwekupisa uye kuputika.Kupisa kwakanyanya kunokonzeresa kuwedzera kwekumanikidza kwemvura, uye tembiricha yakakwira ichakanganisa zvinhu zvevhavha uye kuderedza simba rayo rekubata.
3. Pressure Surge Protection
Isa midziyo yekuyamura yakafanira kana surge suppressors kuti uderedze kukwira kwemhepo uye kudzivirira vharuvhu yeshavishavi kubva pakukasira kudzvanywa spikes inodarika kugona kwayo kwakayerwa.
Muchidimbu, iyo yakanyanya kumanikidza iyo abutterfly valveinogona kumira inotsanangurwa nekugadzirwa kwayo, zvinhu, chimiro, uye nzira yekuisa chisimbiso.Maximum pressure rating ndiyo yakakosha parameter kuti ive nechokwadi chekushanda kwakachengeteka uye kwakanaka kwemavharuvhu eshavishavi.Nekunzwisisa zvinhu zvinokanganisa kuyerwa kwekumanikidza, kuti vanotemerwa sei, uye maitiro avo pakusarudza nekushandiswa kwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha,varovha vuruvo lexi va faneleke va fanele va tshama ku vona ku vhuna ku tshama ku tshama ku tshama ku tshama ku tlula xikombiso lexi nga xikan’wani.
