Iwe une vharafu yakakodzera uye pombi, asi chikanganiso chimwe chidiki panguva yekumisikidza chinogona kukonzera kudonha zvachose. Izvi zvinokumanikidza kutema zvese uye kutanga patsva, kutambisa nguva nemari.

Kuti uise vheji yebhora paPVC pombi, unofanira kutanga wasarudza mhando yekubatanidza yakakodzera: ingave vheji yakasungwa uchishandisa PTFE tepi kana socket valve uchishandisa PVC primer uye simenti. Kugadzirira kwakaringana uye hunyanzvi hwakakosha kune chisimbiso-chisina kubuda.

Kubudirira kwechero basa rekugadzira pombi kunouya pasi pekubatanidza. Kuwana izvi chinhu chandinowanzo kurukura nevabatsiri vakaita saBudi muIndonesia, nekuti vatengi vake vanotarisana neizvi mazuva ese. Ivhavha inobuda inenge isina kumbobvira nekuti vharafu pachayo yakaipa; imhaka yekuti mubatanidzwa hauna kugadzirwa zvakanaka. Nhau dzakanaka ndedzekuti kugadzira chisimbiso chakakwana, chisingaperi chiri nyore kana iwe uchingotevera mashoma akapusa. Sarudzo inonyanya kukosha yauchaita ndeyekusarudza kushandisa shinda kana glue.

Nzira yekubatanidza sei valve yebhora kuPVC?

Iwe unoona shinda uye socket mavharuvhu aripo. Kusarudza isina kunaka kunoreva kuti zvikamu zvako hazvikodzeri, kumisa purojekiti yako kusvika wawana vharafu chaiyo.

Iwe unobatanidza vharafu yebhora kuPVC mune imwe yenzira mbiri. Iwe unoshandisa tambo dzakarukwa (NPT kana BSP) dzekubatanidza masisitimu angangoda kupatsanurwa, kana socket (solvent weld) majoini echigarire, chakanamirwa joint.

Nhanho yekutanga ndeyekugara uchifananidza valve yako kune yako pombi system. Kana mapaipi ako ePVC atove nemagumo ane shinda yechirume, unoda vharuvhu yakarukwa yechikadzi. Asi nokuda kwemabasa akawanda matsva epombi dzemvura, kunyanya pakudiridza kana madziva, iwe uchashandisa socket valves uye solvent simende. Ini ndinogara ndichiona zvichibatsira kana timu yaBudi ichiratidza vatengi tafura kuti vajekese sarudzo. Nzira yacho inotarirwa nevhavha yaunayo. Iwe haugone kunama vharuvhu ine thread kana shinda socket valve. Nzira yakajairika uye yekusingaperi yePVC-to-PVC yekubatanidza ndeyesocket, kanasolvent weld, nzira. Izvi hazvingobatanidzi zvikamu pamwechete; inosanganisa vharafu nepombi nemakemikari kuita chidimbu chimwe chete, chisina musono chepurasitiki, icho chakasimba zvinoshamisa uye chakavimbika kana chaitwa nemazvo.

Yekubatanidza Nzira Kuparadzana

Pane nzira chaiyo yekuisa vharafu yebhora here?

Iwe unofunga kuti valve inoshanda zvakafanana mune chero nzira. Asi kuiisa neinongedzo isiriyo kunogona kudzikamisa kuyerera, kugadzira ruzha, kana kuita kuti zvisaite kushanda gare gare.

Hongu, pane nzira chaiyo. Ivhavha inofanira kuiswa nemubato unosvikika, nzungu dzemubatanidzwa (pavharuvhu yemubatanidzwa) yakamisikidzwa kuti ibviswe nyore, uye nguva dzose iri panzvimbo yakavhurika panguva yekunamatira.

Zvishoma zvidiki zvidiki zvinoparadzanisa yekumisikidzwa kwehunyanzvi kubva kune yeamateur. Chekutanga,kubata orientation. Usati wanamatira chero chinhu, isa vharafu uye ita shuwa kuti mubato une mvumo yakakwana yekutendeudzira yakazara 90 madhigirii. Ndakaona mavharuvhu akaiswa padyo nemadziro zvekuti mubato unongovhura nepakati. Zvinonzwika zviri nyore, asi kukanganisa kwakajairika. Chechipiri, pamavharuvhu edu eChokwadi Union, tinosanganisira nzungu mbiri dzemubatanidzwa. Izvi zvakagadzirirwa kuitira kuti iwe ugone kuzvisunungura uye kusimudza muviri wevharuvhu kunze kwepombi yebasa. Iwe unofanirwa kuisa vharafu ine nzvimbo yakakwana kuti unyatso kusunungura idzi nzungu. Nhanho inonyanya kukosha, zvisinei, inzvimbo yevhavha panguva yekuiswa.

Iyo Yakanyanya Kunetsa Danho: Chengetedza Vhuru Yakavhurika

Paunenge uchinamira (solvent welding) socket valve, valveanofaniraiva munzvimbo yakazaruka zvizere. Izvo zvinonyungudutsa muprimer uye simenti zvakagadzirirwa kunyungudutsa PVC. Kana vharuvhu yakavharwa, izvi zvinonyungudutsa zvinogona kuvharirwa mukati memuviri wevharuvhu uye nemakemikari weld bhora kusvika mukati memukati. Ivhavha ichavharwa zvachose. Ndinoudza Budi ichi ndicho chikonzero chekutanga che "kutadza kwevhavha itsva." Haisi kukanganisa kwevhavha; iko kukanganisa kwekuisa iyo inodzivirirwa ne100%.

Nzira yekunamira sei PVC bhora vharafu?

Iwe unoshandisa glue uye unonamatira zvikamu pamwe chete, asi chibatanidza chinokundikana pasi pekumanikidzwa. Izvi zvinoitika nekuti "gluing" inyaya yemakemikari inoda matanho chaiwo.

Kuti unyatsonamira PVC bhora vharafu, unofanira kushandisa nhanho mbiri primer uye simende nzira. Izvi zvinosanganisira kuchenesa, kuisa purple primer kune ese ari maviri, wozoisa PVC simende usati wabatanidza iwo nekumonyoroka.

Izvi zvinodaidzwa kunzi solvent welding, uye zvinogadzira chisungo chakasimba kupfuura pombi pachayo. Kusvetuka nhanho ivimbiso yekuvuza mune ramangwana. Heino maitiro atinodzidzisa vatengesi veBudi kuti vatevedzere:

1. Dry Fit Kutanga.Ita shuwa kuti pombi yabuda mukati mesocket yevharuvhu.
2. Chenesa Zvikamu Zvose.Shandisa jira rakachena, rakaoma kupukuta chero tsvina kana hunyoro kubva kunze kwepombi uye mukati mevhavha socket.
3. Isa Primer.Shandisa dauber kuisa jasi rakasununguka rePVC primer kune kunze kwepombi kupera uye mukati mesoketi. Iyo primer inochenesa pasi uye inotanga kupfavisa plastiki. Iri ndiro danho rakanyenyeredzwa uye rakanyanya kukosha.
4. Isa Cement.Nepo iyo primer ichiri kunyorova, shandisa imwe nhanho yePVC simende pamusoro penzvimbo dzakagadzirirwa. Usashandise zvakawandisa, asi iva nechokwadi chekuvhara zvizere.
5. Batanidza uye Twist.Pakarepo sundira pombi musocket kusvika yabuda. Paunenge uchisundidzira, ipa iyo quarter-turn. Kufamba uku kunoparadzira simende zvakaenzana uye kunobvisa chero mabhuru emhepo akavharirwa.
6. Bata Upore.Bata chibatanidza zvakasimba panzvimbo kwemasekondi makumi matatu kudzivirira pombi kuti isasundire kumashure. Usabate kana kuvhiringidza mubatanidzwa kwemaminetsi angangoita gumi nemashanu, uye bvumira kuti chirape zvizere zvinoenderana nemirairo yemugadziri we simende usati wadzvanya system.

Iwe unoita sei kuti PVC bhora vharafu rive nyore?

Varuvhu yako nyowani yakaoma kwazvo, uye urikunetsekana nekubvarura mubato. Kuomarara uku kunogona kuita kuti iwe ufunge kuti vharuvhu haina kukwana kana ichitova chiratidzo chemhando.

Itsva, yemhando yepamusoro PVC vharuvhu yakaoma nekuti zvigaro zvayo zvePTFE zvinogadzira chisimbiso chakakwana, chakasimba pakurwisa bhora. Kuita kuti zvireruke, shandisa chipanera paskweya nzungu pahwaro hwemubato kuti uwedzere kukwirisa kuti upatse.

Ndinowana mubvunzo uyu nguva dzese. Vatengi vanogamuchira Pntek yedumavharuvhuuye vanoti vakanyanya kuoma kutendeuka. Izvi nemaune. Mhete chena mukati, zvigaro zvePTFE, zvakanyatsoumbwa kuti zvigadzire chisimbiso chinosunga bubble. Kubata ikoko ndiko kunodzivirira kubuda. Mavharuvhu akachipa ane zvisimbiso zvakasununguka anoshanduka nyore, asi anokundikanawo nekukurumidza. Funga nezvayo seshangu itsva dzematehwe; dzinoda kuputswa mukati. Nzira yakanakisisa yekuita izvi ndeyokushandisa chipanera chiduku chinogadziriswa pane gobvu, mativi mana echikamu chemubato wemubato, nechepasi chaipo. Izvi zvinokupa iwe yakawanda yekuwedzera pasina kuisa kushushikana paT-mubato pachayo. Mushure mekuvhura nekuivhara kakati wandei, ichava yakanyanya kutsetseka.Usamboshandisa WD-40 kana mamwe mafuta-based lubricant.Izvi zvigadzirwa zvinogona kurwisa uye kunetesa purasitiki yePVC uye EPDM O-ring seals, zvichiita kuti valve ikundike nekufamba kwenguva.

Mhedziso

Kuiswa kwakakodzera, uchishandisa nzira yekubatanidza kwayo, kutarisisa, uye gluing maitiro, ndiyo chete nzira yekuvimbisa aPVC bhora vharafuinopa hupenyu hurefu, hwakavimbika, husina kubvinza.
