PVC inoongororwa sei kuti ine simba rekumanikidza?

Mutengi wako anofunga kuti zvikamu zvese zvePVC zvakafanana. Chikanganiso ichi chine njodzi chinogona kuita kuti vashandise pombi isina giredhi rakawanda ine vharuvhu ine giredhi rakakwirira, zvichiita kuti pave nebhomba rinotora nguva yakawanda musystem yavo.

Kumanikidzwa kwePVC kunoenderana nekukora kwemadziro ayo (Schedule) uye dhayamita. Pombi yeStandard Schedule 40 inogona kubva pa400 PSI yehukuru hudiki kusvika pasi pe200 PSI yehukuru hukuru.

Chikanganiso chakajairika kufunga kuti sisitimu inopihwa 150 PSI nekuda kwekuti vharuvhu yebhora ndiyo yakasimba. Ndinogara ndichisimbisa kuna Budi kuti sisitimu yese yakasimba chete sechikamu chayo chisina kusimba. Kuyera kwekumanikidzwa kwePVCpombiyakasiyana nevharuvhu. Inotsanangurwa ne "Schedule" yayo, iyo inoreva ukobvu hwemadziro.

• Purogiramu 40:Uhu ndihwo ukobvu hwemadziro hunoshandiswa pakushandisa pombi dzemvura nekudiridza.
• Purogiramu 80:Pombi iyi ine madziro akakora zvikuru uye, nekudaro, ine kumanikidzwa kwakanyanya. Inowanzoshandiswa mumaindasitiri.

Chinhu chikuru ndechekuti chiyero chekumanikidzwa chinochinja zvichienderana nehukuru hwepombi. Heino kuenzanisa kuri nyore kwepombi yeSchedule 40 pa73°F (23°C):

Sisitimu ine mapaipi e4″ Sch 40 uye mavharuvhu edu ebhora e150 PSI ane kumanikidzwa kwakanyanya kwekushanda kwe150 PSI. Unofanira kugara uchigadzira chikamu chakaderera.

Chii chinonzi pressure rating yebhora vharuvhu?

Unoona vharuvhu yebrass yakarongwa kuti ive 600 PSI uye vharuvhu yePVC ye150 PSI. Kusanzwisisa kuti sei vakasiyana kunogona kuita kuti zviome kusarudza yakakodzera basa racho.

Kuyera kwekumanikidzwa kwevharuvhu yebhora kunoenderana nezvinhu zvayo uye kuvakwa kwayo. Mavharuvhu ePVC anowanzo kuve 150 PSI, nepo mavharuvhu esimbi akagadzirwa nendarira kana simbi anogona kuve 600 PSI kusvika 3000 PSI.

Izwi iri"Vharuvhu yebhora"inotsanangura mashandiro acho, asi kugona kudzvanywa kunobva pazvinhu zvirimo. Inyaya yekare yekushandisa chishandiso chakakodzera pabasa racho. Kune vatengi vake, timu yaBudi inofanira kuvatungamira zvichienderana nekushandisa kwacho.

Zvinhu Zvikuru Zvinoona Kuyera Kumanikidzwa:

1. Zvinhu zvemuviri:Ichi ndicho chinhu chikuru. PVC yakasimba, asi simbi yakasimba. Ndarira isarudzo yakajairika yemvura inopisa yemumba uye kushandiswa kwakajairika kusvika ku600 PSI. Simbi yekabhoni nesimbi isingatsvi zvinoshandiswa mumaindasitiri ane simba rakawanda uko kumanikidzwa kunogona kuva muzviuru zvePSI.
2. Chigaro & Chisimbiso Zvinhu:Zvikamu "zvinyoro" zviri mukati mevharuvhu, sezvigaro zvePTFE zvinoshandiswa nemavharuvhu edu ePntek, zvinewo muganho wekumanikidzwa uye tembiricha. Zvinofanira kukwanisa kugadzira chisimbiso pasina kukanganiswa kana kuparadzwa nekumanikidzwa kwesystem.
3. Kuvaka:Magadzirirwo anoitwa muviri wevharuvhu ane basa guru mukusimba kwawo.

A Mavharuvhu ePVCChiyero che150 PSI chakakwana pakushandiswa kwemvura kwakawanda kwayakagadzirirwa, sekudiridza, madziva, uye pombi dzemvura dzemumba.

Chii chinonzi chiyero chekumanikidzwa kwevharuvhu?

Unoona "150 PSI @ 73°F" pa valvu. Kana ukanyatsotarisa pa150 PSI chete worega tembiricha, unogona kuisa valvu pamutsetse painovimbiswa kuti ichakundikana.

Chiyero chekumanikidzwa kwevharuvhu ndicho chiyero chepamusoro chekushanda chakachengeteka chinogona kubatwa nevharuvhu patembiricha yakatarwa. Kune mavharuvhu emvura, izvi zvinowanzonzi chiyero cheCold Working Pressure (CWP).

Tsanangudzo iyi ine zvikamu zviviri—kumanikidzwaattembiricha—ndiyo pfungwa inonyanya kukosha yekudzidzisa. Hukama hwacho huri nyore: sezvo tembiricha ichikwira, simba rePVC rinodzikira, uye ndizvo zvinoitawo kumanikidzwa kwayo. Izvi zvinonzi "de-rating." Mavharuvhu edu ePntek anoongororwa kuti ane 150 PSI patembiricha yemukamuri yemvura. Kana mutengi wako akaedza kushandisa vharuvhu imwecheteyo pamutsetse wemvura ye120°F (49°C), kumanikidzwa kwakachengeteka kwaanogona kubata kunogona kudzikira ne50% kana kupfuura. Mugadziri wese ane mukurumbira anopa chati yekudzikisa kumanikidzwa kunoratidza kumanikidzwa kwakanyanya kunobvumirwa patembiricha yakakwira. Ndakava nechokwadi chekuti Budi ine machati aya ezvigadzirwa zvedu zvese. Kuregeredza hukama uhwu ndicho chikonzero chikuru chekukundikana kwezvinhu mumasisitimu epombi dzethermoplastic.

Chii chinonzi pressure rating yeClass 3000 ball valve?

Mutengi wemuindasitiri anokumbira vharuvhu ye "Class 3000″". Kana usingazive kuti izvi zvinorevei, ungaedza kutsvaga yakaenzana nePVC, iyo isipo, uye inoratidza kushaya ruzivo.

Vharuvhu yebhora yeClass 3000 ivharuvhu yeindasitiri ine simba guru yakagadzirwa nesimbi yakagadzirwa, ine chiyero chekubata 3000 PSI. Iri iboka rakasiyana zvachose nemavharuvhu ePVC uye rinoshandiswa pakugadzira mafuta negasi.

Mubvunzo uyu unobatsira kudhirowa mutsetse wakajeka mujecha wekushandiswa kwechigadzirwa. Kuyera kwe "Class" (semuenzaniso, Kirasi 150, 300, 600, 3000) chikamu chechiyero cheANSI/ASME chinoshandiswa kuma flange nemavharuvhu emaindasitiri, kazhinji akagadzirwa nesimbi. Sisitimu iyi yekuyera yakaoma zvikuru kupfuura kuyera kweCWP kuri nyore pavharuvhu yePVC. AVharuvhu yekirasi 3000haisi yekumanikidzwa kwakanyanya chete; yakagadzirirwa tembiricha dzakanyanya uye nzvimbo dzakaoma sedzinowanikwa muindasitiri yemafuta negesi. Ichi chigadzirwa chakakosha chinodhura mazana kana zviuru zvemadhora. Kana mutengi akakumbira izvi, anenge achishanda muindasitiri chaiyo isingakodzeri PVC. Kuziva izvi kunobvumira timu yaBudi kuona application nekukasika uye kudzivirira kutaura pabasa apo zvigadzirwa zvedu zvingashandiswa zvisirizvo zvine njodzi. Zvinosimbisa hunyanzvi nekuziva zvauriusadarotengesa, chero zvaunoita.

Mhedziso

Chiyero chekumanikidzwa kwevharuvhu yebhora rePVC chinowanzova 150 PSI patembiricha yemumba, asi izvi zvinodzikira kana kupisa kuchikwira. Gara uchienzanisa vharuvhu nezvinodiwa nedzvinyiriro uye tembiricha yesystem.
