Yakawanda sei kudzvanywa kwakayerwa PVC?

Mutengi wako anofunga kuti zvikamu zvese zvePVC zvakafanana. Ichi chikanganiso chine njodzi chinogona kutungamira kwavari kushandisa pombi yakaderera-yakatemerwa nevharuvhu yakakwira, vachigadzira bhomba renguva yekumaka muhurongwa hwavo.

Kudzvanywa kwePVC kunoenderana nekukobvu kwemadziro (Schedule) uye dhayamita. Standard Schedule 40 pombi inogona kubva pamusoro pe400 PSI yemadiki madiki kusvika pasi pe200 PSI kune makuru.

Kukanganisa kwakajairika kufunga kuti system yakatemerwa 150 PSI nekuda kwekuti vharafu yebhora iri. Ini ndinogara ndichisimbisa kuBudi kuti iyo system yese yakasimba chete sechikamu chayo chisina kusimba. Chiyero chekumanikidza chePVCpombiyakasiyana nevhavha. Inotsanangurwa ne "Kuronga," iyo inoreva kukora kwemadziro.

• Chirongwa 40:Uyu ndiwo muyero wemadziro ukobvu kune mazhinji emvura pombi uye kudiridza.
• Chirongwa 80:Iyi pombi ine madziro akanyanya kukora uye, nekudaro, yakanyanya kukwirira kudzvanywa chiyero. Inonyanya kushandiswa mumaindasitiri ekushandisa.

Chinokosha chekutora ndechekuti chiyero chekumanikidza chinoshanduka nehukuru hwepombi. Heino kuenzanisa kuri nyore kweChirongwa 40 pombi pa73°F (23°C):

Sitimu ine 4 ″ Sch 40 pombi uye yedu 150 PSI bhora mavharuvhu ane yakanyanya kushanda kumanikidza ye150 PSI. Iwe unofanirwa kugara uchigadzira chikamu chepasi-chakayerwa.

Chii chinonzi pressure rating yevharuvhu yebhora?

Iwe unoona vharafu yendarira yakarongerwa 600 PSI uye PVC valve ye150 PSI. Kusanzwisisa kuti sei vakasiyana kunogona kuita kuti zviome kupembedza kusarudza yakakodzera yebasa racho.

Kutsikirirwa kwevharuvhu yebhora kunotarwa nezvinhu zvayo uye kuvaka. Mavharuvhu ePVC anowanzo 150 PSI, ukuwo mavharuvhu esimbi akagadzirwa nendarira kana simbi anogona kuverengerwa 600 PSI kusvika pamusoro pe3000 PSI.

Izwi rokuti"bhora vharafu"inotsanangura basa, asi simba rekumanikidza rinobva kuzvinhu. Inyaya yechinyakare yekushandisa chishandiso chakakodzera chebasa racho. Kune vatengi vake, timu yaBudi inofanirwa kuvatungamira zvichienderana nekushandisa.

Zvinhu Zvikuru Kuona Kudzvanyirira Rating:

1. Body Material:Ichi ndicho chinhu chikuru. PVC yakasimba, asi simbi yakasimba. Brass isarudzo yakajairika yekugara mvura inopisa uye general-chinangwa kunyorera kusvika ku600 PSI. Carbon simbi uye simbi isina tsvina inoshandiswa kune yakakwira-kumanikidza maindasitiri maitiro uko kudzvanywa kunogona kuve muzviuru zvePSI.
2. Chigaro & Chisimbiso Material:Izvo zvikamu "zvakapfava" mukati mevharuvhu, senge PTFE inogara mavharuvhu edu ePntek anoshandisa, anewo kumanikidza uye tembiricha miganhu. Vanofanira kukwanisa kugadzira chisimbiso pasina kuremara kana kuparadzwa nekumanikidza system.
3. Kuvaka:Nzira iyo muviri wevharuvhu wakaunganidzwa nayo inoita basa mukusimba kwayo.

A PVC valves150 PSI chiyero chakakwana kune akawanda maapplication emvura ayo akagadzirirwa, sekudiridza, madziva, uye pombi dzekugara.

Chii chinonzi valve pressure rating?

Iwe unoona "150 PSI @ 73 ° F" pamutumbi wevharuvhu. Kana iwe ukangotarisa pa150 PSI uye usingatarise tembiricha, unogona kuisa vharafu pamutsetse waunovimbiswa kutadza.

A valve pressure rating ndiyo yakanyanya kuchengetedzwa yakachengeteka kushandiswa kwevhavha inogona kubata pane imwe tembiricha. Pamavharuvhu emvura, izvi zvinowanzodaidzwa kuti Cold Working Pressure (CWP) rating.

Iyi tsanangudzo yezvikamu zviviri-kumanikidzaattembiricha—ndiyo pfungwa inokosha zvikuru yokudzidzisa. Hukama huri nyore: sezvo tembiricha ichikwira, simba rePVC zvinhu rinodzika, uye ndizvo zvinoita kudzvanywa kwayo. Izvi zvinonzi "de-rating." Yedu mavharuvhu ePntek akatemerwa 150 PSI panzvimbo yakajairwa tembiricha yemvura yekamuri. Kana mutengi wako akaedza kushandisa vharafu imwe chete iyoyo pamutsetse une 120 ° F (49 ° C) mvura, dzvinyiriro yakachengeteka yainokwanisa kubata inogona kuderera ne50% kana kupfuura. Wese mugadziri ane mukurumbira anopa de-rating chati inoratidza yakanyanya kubvumidzwa kudzvanywa patembiricha yepamusoro. Ndakava nechokwadi chekuti Budi ine machati aya ezvigadzirwa zvedu zvese. Kuregeredza hukama uhu ndicho chikonzero chekutanga chekutadza kwezvinhu mune thermoplastic pombi masisitimu.

Chii chinonzi pressure rating yeClass 3000 ball valve?

Mutengi wemumaindasitiri anokumbira vharafu "Kirasi 3000". Kana usingazive kuti izvi zvinorevei, unogona kuedza kutsvaga yakaenzana nePVC, iyo isipo, uye inoratidza kushomeka kwehunyanzvi.

A Kirasi 3000 bhora vharafu ivharuvhu inodzvanyirira maindasitiri yakagadzirwa nesimbi yakaumbwa, yakaverengerwa kubata 3000 PSI. Ichi chikamu chakasiyana zvachose kubva kuPVC mavharuvhu uye inoshandiswa mafuta uye gasi.

Uyu mubvunzo unobatsira kudhirowa mutsara wakajeka mujecha rekushandisa chigadzirwa. Zviyero zve "Kirasi" (semuenzaniso, Kirasi 150, 300, 600, 3000) chikamu cheiyo ANSI/ASME mwero unoshandiswa kumaindasitiri flanges nemavharuvhu, anogara akagadzirwa nesimbi. Iyi yekuyera sisitimu yakanyanya kuomarara kupfuura yakareruka CWP chiyero paPVC valve. AKirasi 3000 vharafuhaisi yekumanikidza yakakwira chete; yakagadzirirwa kutonhora kwakanyanya uye nharaunda dzakaoma sedziya dzinowanikwa muindasitiri yemafuta negasi. Icho chigadzirwa chakakosha chinodhura mazana kana zviuru zvemadhora. Kana mutengi achikumbira izvi, vari kushanda mune imwe indasitiri isingakodzeri PVC. Kuziva izvi kunobvumira timu yeBudi kuti ikurumidze kuona chikumbiro uye kudzivirira kutora mashoko pabasa apo zvigadzirwa zvedu zvinogona kushandiswa zvisizvo. Inosimbisa hunyanzvi nekuziva zvauriusadarotengesai, sezvamunoita.

Mhedziso

A PVC ball valve's pressure rating inowanzoita 150 PSI pakamuri tembiricha, asi izvi zvinodonha sezvo kupisa kunowedzera. Gara uchifananidza vharafu nekumanikidza kwehurongwa uye tembiricha zvinoda.
