Une vharuvhu nepaipi zvakakodzera, asi chikanganiso chidiki chimwe chete panguva yekuisa chinogona kukonzera kubuda kwemvura zvachose. Izvi zvinokumanikidza kuti ubvise zvese wotanga patsva, uchipedza nguva nemari.

Kuti uise vharuvhu yebhora papombi yePVC, unofanira kutanga wasarudza rudzi rwakakodzera rwekubatanidza: ingava vharuvhu ine shinda uchishandisa tepi yePTFE kana vharuvhu yesoketi inoshandisa primer nesimende yePVC. Kugadzirira kwakakodzera uye matekiniki zvakakosha kuti chisimbiso chisadonhe.

Kubudirira kwebasa remapombi kunobva pakubatanidza. Kuita izvi nemazvo chinhu chandinowanzo kurukura nevatinoshanda navo vakaita saBudi muIndonesia, nekuti vatengi vake vanosangana nazvo zuva nezuva. Vharuvhu inodonhedza mvura haiwanzoitiki nekuti vharuvhu pachayo yakaipa; imhaka yekuti joinhi haina kugadzirwa nemazvo. Mashoko akanaka ndeekuti kugadzira chisimbiso chakakwana, chisingaperi kuri nyore kana ukangotevera matanho mashoma ari nyore. Sarudzo yakakosha yauchaita kusarudza kana uchishandisa shinda kana guruu.

Nzira yekubatanidza vharuvhu yebhora kuPVC?

Unoona mavharuvhu ane shinda nemasokisi aripo. Kusarudza risiri iro zvinoreva kuti zvikamu zvako hazvikwane, zvichimisa purojekiti yako kusvika wawana vharuvhu chaiyo.

Unobatanidza vharuvhu yebhora kuPVC nenzira imwe yenzira mbiri. Unoshandisa tambo (NPT kana BSP) dzekubatanidza masisitimu angangoda kuparadzaniswa, kana kubatanidza socket (solvent weld) yejoin rinogara riripo, rakanamirwa.

Danho rekutanga nderekubatanidza vharuvhu yako nehurongwa hwemapaipi ako. Kana mapaipi ako ePVC atove nemagumo eshinda dzechirume, unoda vharuvhu yechikadzi ine shinda. Asi pamabasa mazhinji matsva epombi, kunyanya ekudiridza kana emadziva ekushambira, uchashandisa mavharuvhu emasokisi nesimende yekunyungudutsa. Ndinogara ndichiwana zvichibatsira kana timu yaBudi ichiratidza vatengi tafura yekujekesa sarudzo. Nzira yacho inosarudzwa nevharuvhu yaunayo. Haugone kunamira vharuvhu ine shinda kana kupinza vharuvhu yemasokisi. Nzira yakajairika uye inogara iripo yekubatanidza PVC-to-PVC ndeyesoketi, kanaweld yekunyungudutsaMaitiro aya haangonamati zvikamu chete; anobatanidza vharuvhu nepaipi nemakemikari kuita purasitiki imwe chete isina musono, iyo yakasimba zvikuru uye yakavimbika kana ikaitwa nemazvo.

Kupatsanurwa kweNzira yeKubatanidza

Pane nzira chaiyo yekuisa vharuvhu yebhora here?

Unofunga kuti vharuvhu inoshanda zvakafanana chero kupi zvako. Asi kuiisa isina kurongeka zvakanaka kunogona kudzikamisa kuyerera kwemvura, kugadzira ruzha, kana kuita kuti zvisakwanise kugadziriswa gare gare.

Ehe, pane nzira chaiyo. Vharuvhu inofanira kuiswa nemubato uri nyore kusvika, union nuts (pavharuvhu chaiyo ye union) dzakaiswa kuti dzibviswe zviri nyore, uye nguva dzose dziri pachena panguva yekunamira.

Zvinhu zvidiki zvakati wandei zvinoparadzanisa kuiswa kwehunyanzvi kubva kune kwevasina kudzidza.kurongeka kwemubato. Usati wanama chero chinhu, isa vharuvhu uye iva nechokwadi chekuti mubato wacho une nzvimbo yakakwana yekutenderedza madhigirii makumi mapfumbamwe. Ndakaona mavharuvhu akaiswa pedyo nemadziro zvekuti mubato wacho unogona kuvhurika pakati chete. Zvinonzwika zviri nyore, asi chikanganiso chinowanzoitika. Chechipiri, pamavharuvhu edu eTrue Union, tinosanganisira manyuchi maviri eunion. Aya akagadzirwa kuitira kuti ugone kuasunungura wosimudza muviri wevharuvhu kubva mupombi kuti uishandise. Unofanira kuisa vharuvhu ine nzvimbo yakakwana yekusunungura manyuchi aya. Danho rakakosha zvikuru, zvisinei, mamiriro evharuvhu panguva yekuisa.

Danho Rinonyanya Kukosha: Chengeta Vharuvhu Yakavhurika

Kana uchinamira vharuvhu yesoketi neglue (socket welding), vharuvhu yachozvinofaniraIva munzvimbo yakavhurika zvizere. Zvinonyungudutsa zviri muprimer nesimende zvakagadzirwa kuti zvinyungudike PVC. Kana vharuvhu ikavharwa, zvinonyungudutsa izvi zvinogona kubatwa mukati memuviri wevharuvhu uye zvinobatanidza bhora nemakemikari mugomba remukati. Vharuvhu ichavharwa zvachose. Ndinoudza Budi kuti ichi ndicho chikonzero chikuru che "kukundikana kwevharuvhu itsva." Haisi dambudziko revharuvhu; kukanganisa kwekuisa kunogona kudzivirirwa zvizere.

Nzira yekunamira sei vharuvhu yebhora rePVC?

Unoisa guruu wobatanidza zvikamu zvacho, asi gumbo rinokundikana kana wamanikidzwa. Izvi zvinoitika nekuti "kuruka" chaizvoizvo inzira yemakemikari inoda matanho chaiwo.

Kuti unamate vharuvhu yebhora rePVC nemazvo, unofanirwa kushandisa nzira yeprimer ine matanho maviri nesimende. Izvi zvinosanganisira kuchenesa, kuisa primer yepepuru pamusoro pese, wozoisa simende yePVC usati wabatanidza netwist.

Maitiro aya anonzi solvent welding, uye anogadzira chisungo chakasimba kupfuura pombi pachayo. Kusvetuka matanho ivimbiso yekubuda kwemvura mune ramangwana. Heino maitiro atinodzidzisa vagovanisi veBudi kuti vatevere:

1. Kuomesa Kukwana Kutanga.Iva nechokwadi chekuti pasi pepombi iri mukati mesokisi yevharuvhu.
2. Chenesa Zvikamu Zvose.Shandisa jira rakachena, rakaoma kupukuta tsvina kana hunyoro kubva kunze kwepombi nemukati mesokisi revharuvhu.
3. Isa Primer.Shandisa dauber kuisa jira rePVC primer kunze kwepombi nemukati mesoketi. Primer inochenesa pamusoro nemakemikari uye inotanga kunyorovesa purasitiki. Iri ndiro danho rakasiiwa zvakanyanya uye rakakosha.
4. Isa simende.Kana primer ichiri yakanyorova, isa PVC simende yakaenzana panzvimbo dzakagadziriswa primer. Usashandise yakawandisa, asi iva nechokwadi chekuti yakafukidzwa zvakakwana.
5. Batanidza uye Monyorora.Pakarepo pinza pombi musoketi kusvika yadzika pasi. Paunosunda, itenderedze nekota. Kufamba uku kunoparadzira simende zvakaenzana uye kunobvisa mabubble emhepo akavharirwa.
6. Bata uye Poresa.Bata chisungo chacho zvakasimba kwemasekondi angangoita makumi matatu kudzivirira pombi kuti isasundire shure. Usabata kana kukanganisa chisungo chacho kweinenge maminitsi gumi nemashanu, uye rega chinyatsopora zvichienderana nemirairo yemugadziri wesimende usati wadzvanya sisitimu.

Unoita sei kuti vharuvhu yebhora rePVC itendeuke zviri nyore?

Vharuvhu yako itsva yakaoma zvikuru, uye unonetseka nezvekudambura mubato. Kuomarara uku kunogona kukuita kuti ufunge kuti vharuvhu haina kunaka asi ichi chiratidzo chemhando yepamusoro.

Vharuvhu itsva yePVC yemhando yepamusoro yakaoma nekuti zvigaro zvayo zvePTFE zvinogadzira chisimbiso chakasimba uye chakakwana pabhora. Kuti ritenderere zviri nyore, shandisa chipanera pa square nati iri pasi pemubato kuti uwane simba riri nani rekuipwanya.

Ndinogara ndichibvunzwa mubvunzo uyu. Vatengi vanogamuchira Pntek yedumavharuvhuuye vanoti dzakaoma kutenderedza. Izvi zvinoitwa nemaune. Mhete chena dziri mukati, zvigaro zvePTFE, dzakagadzirwa nemazvo kuti dzigadzire chisimbiso chakasimba semabhurumu. Kusimba ikoko ndiko kunodzivirira kubuda kwemvura. Mavharuvhu akachipa ane zvisimbiso zvakasununguka anotenderera zviri nyore, asi anokundikanawo nekukurumidza. Funga nezvazvo seshangu itsva dzedehwe; dzinofanira kupwanywa. Nzira yakanakisa yekuita izvi ndeyekushandisa chipanera chidiki chinogadziriswa panzvimbo yakakora, yakaenzana nemativi mana emubato, pachigadziko chaipo. Izvi zvinokupa simba rakawanda pasina kuisa simba pabato reT pacharo. Mushure mekuvhura nekuvhara kashoma, rinozonyatsonaka.Usamboshandisa WD-40 kana mamwe mafuta anozorwa.Zvigadzirwa izvi zvinogona kurwisa nekushayisa simba mapurasitiki ePVC nezvisimbiso zveEPDM O-ring, zvichiita kuti vharuvhu iome nekufamba kwenguva.

Mhedziso

Kuisa kwakakodzera, uchishandisa nzira chaiyo yekubatanidza, kurongeka, uye maitiro ekunamira, ndiyo chete nzira yekuona kutiVharuvhu yebhora yePVCinopa hupenyu hwebasa hurefu, hwakavimbika, husina kudonhedza mvura.
