Wakacheka, asi chisimbiso chinodonha chinoreva kutambisa nguva, mari, uye zvinhu. Rimwe rakashata rakabatana pamutsetse wePVC rinogona kukumanikidza kutema chikamu chose uye kutanga patsva.

Kuisa valve yebhora paPVC pombi, unoshandisa solvent welding. Izvi zvinosanganisira kucheka pombi zvakachena, kubvisa, kuisa PVC primer uye simende kune ese ari maviri, wobva waasundidzira pamwe chete nekota twist uye kubata zvakasimba kusvikira kemikari bond yamira.

Uku hakusi kungonamira; ikemikari nzira inosanganisa plastiki kuita chidimbu chimwe chete, chakasimba. Kuzvigadzirisa hazvigone kutaurirana kune avo vakanaka. Ipoindi yandinogara ndichishushikana nevadiwa vakaita saBudi kuIndonesia. Vatengi vake, vangave vari makondirakiti makuru kana vatengesi vemunharaunda, zvinoenderana nekuvimbika. Mubatanidzwa wakakundikana hakusi kungobvinza; kunonoka kweprojekiti uye kukanganisa mukurumbira wavo. Ngatifungei mibvunzo yakakosha kuita kuti kugadzwa kwese kubudirire.

Ungabatanidza sei vharuvhu kune pombi yePVC?

Une vharafu muruoko, asi uri kutarisa pombi yakatsetseka. Iwe unoziva kune akasiyana marudzi ekubatanidza, asi ndeipi yakanakira basa rako kuvimbisa yakasimba, isina inovuza-isina system?

Iwe unobatanidza vharafu kuPVC pombi mune imwe yenzira mbiri: yekusingaperi solvent-weld (socket) yekubatanidza, iyo yakanakira PVC-to-PVC, kana serviceable yakarukwa yekubatanidza, yakanakira kujoinha PVC kune esimbi zvikamu sepombi.

Kusarudza nzira yakakodzera ndiyo danho rekutanga kune yekumisikidzwa kwehunyanzvi. Kune masisitimu ari akazara PVC,solvent weldingndiyo chiyero cheindasitiri. Inogadzira mubatanidzwa usina musono, wakabatana wakasimba sepombi pachayo. Nzira yacho inokurumidza, yakavimbika, uye isingagumi. Zvisungo zvakabatanidzwa zvinoshandiswa paunenge uchida kubatanidza mutsara wako wePVC kune chimwe chinhu chine tambo dzesimbi dziripo, kana iwe uchitarisira kuti unoda kubvisa valve nyore nyore gare gare. Nekudaro, machira epurasitiki akaiswa anofanirwa kuisirwa nekuchenjera kudzivirira makatsemuka kubva pakunyanya-kuomesa. Kune akawanda akajairwa PVC mapaipi, ini ndinogara ndichikurudzira kusimba uye kupusa kweiyo solvent-weld yekubatanidza. Kana kushanda kwakakosha, achokwadi mubatanidzwa bhora vharafuinokupa zvakanakisa zvepasirese.

Ndeipi nzira yakarurama yekuisa vheji yebhora?

Iyo valve yakanamirwa mukati zvakakwana, asi ikozvino mubato unorova madziro uye haugone kuvhara. Kana kuti iwe wakaisa yechokwadi vheji yemubatanidzwa yakasimba pagokora zvekuti haugone kuwana wrench pairi.

"Nzira yakarurama" yekuisa valve yebhora ndeyekuronga kushanda kwayo. Izvi zvinoreva kuti yakaoma-yakakodzera kutanga kuve nechokwadi kuti mubato une yakazara 90-dhigirii inotenderera radius uye kuti nzungu dzemubatanidzwa dzinowanikwa zvakakwana kuti dzigadziriswe mune ramangwana.

Kuiswa kwakabudirira kunopfuura kungopfuura aleak-proof chisimbiso; ndezvekushanda kwenguva refu. Apa ndipo apo miniti yekuronga inochengetedza awa rework. Usati watombovhura primer, isa vharafu munzvimbo yayo yaunoda uye zunza mubato. Inofamba zvakasununguka kubva pakazaruka kusvika pakavharwa zvakazara here? Kana zvisina kudaro, unofanirwa kugadzirisa maitiro ayo. Chechipiri, kana uri kushandisa yepamusoro-mhandochokwadi chekubatana valveseyedu paPntek, unofanirwa kuve nechokwadi kuti unokwanisa kuwana nzungu dzemubatanidzwa. Chinangwa chemavharuvhu aya ndechekubvumira kubviswa kwemuviri wevhavha pasina kucheka pombi. Ndinogara ndichiyeuchidza Budi kuti audze vatengi vake izvi: kana iwe usingakwanise kuwana wrench panzungu, wakunda chinangwa chose chevhavha. Funga nezvayo sekuisa kwete kwanhasi chete, asi kune munhu anofanirwa kuishandisa makore mashanu kubva zvino.

PVC bhora mavharuvhu akananga here?

Wagadzirira nesamende, asi unombomira, uchinetsekana uchitsvaga museve wekuyerera pamutumbi wevharuvhu. Unoziva kunamira vharuvhu yekudzokera kumashure kungave njodzi, kukanganisa kunodhura.

Kwete, yakajairwa PVC bhora vharafu haisi directional; ine divi-directional. Iyo inoshandisa symmetrical dhizaini ine zvisimbiso pamativi ese, ichiibvumira kuvhara kuyerera zvakaenzana kubva kune chero nzira. Iyo chete "gwara" rekunetsekana pamusoro paro kutaridzika kwayo kwemubato kuwana.

Uyu mubvunzo wakanaka uye wakajairika. Kuchenjerera kwako kwakakodzera nekuti mamwe mavharuvhu, sengecheki mavharuvhukana mavharuvhu epasi, anonyatso kutungamira uye anotadza kana akaiswa kumashure. Vane museve wakasiyana pamuviri wekutungamirira. Abhora vharafu, zvisinei, inoshanda zvakasiyana. Nheyo yaro ibhora riri nyore rine buri mukati maro, rinotenderera kuti rivhare chigaro. Sezvo paine chigaro pamativi ese ari kumusoro nekudzika kwebhora, inogadzira chisimbiso chakasimba zvisinei nekuti kumanikidza kuri kubva nenzira ipi. Saka, unogona kuzorora. Iwe haugone kuisa yakajairika bhora vharafu "kumashure" maererano nekuyerera. Ichi chakareruka, chakasimba dhizaini ndicho chikonzero ivo vakakurumbira. Ingotarisa pakuimisa kuitira kuti mubato uye mibatanidzwa zvive nyore kusvika.

Akavimbika sei mavharuvhu ebhora ePVC?

Waona yakachipa, isina-zita PVC vharafu ichitsemuka kana kudonha mushure megore chete, zvichiita kuti ubvunze izvo izvo pachazvo. Iwe unoshamisika kana iwe uchifanira kungoshandisa inodhura simbi valve.

Yepamusoro-mhando PVC bhora mavharuvhu akavimbika zvakanyanya uye anogona kugara kwemakumi emakore. Upenyu hwavo hunotaridzirwa nehutano hwezvinhu zvakasvibiswa (mhandara vs. PVC yakadzorerwa), kunyatsogadzirwa kwekugadzira, uye kuiswa kwakakodzera. Ivhavha yemhando inowanzopfuura system yairi.

Kuvimbika kwe aPVC bhora vharafuzvinosvika pakuti inogadzirwa nei uye kuti inogadzirwa sei. Uyu ndiwo musimboti wehuzivi hwedu paPntek.

Chii Chinoratidza Kuvimbika?

• Hunhu Hwezvinhu:Isu tinosimbisa kushandisa100% mhandara PVC. Mavharuvhu mazhinji akachipa anoshandisa zvakadzokororwa kana kuzadza zvinhu, izvo zvinoita kuti purasitiki iite brittle uye kutadza kukundikana pasi pekumanikidzwa kana kuratidzwa kweUV. Mhandara PVC inopa simba repamusoro uye makemikari kuramba.
• Manufacturing Precision:Kugadzirwa kwedu otomatiki kunoita kuti vharafu yega yega yakafanana. Bhora rinofanira kunge rakaita denderedzwa uye zvigaro zvakanyatsotsetseka kuti zvigadzire chisimbiso chinosunga bubble. Isu tinomanikidza-yedza mavharuvhu edu kune mwero wakakwira zvakanyanya kupfuura zvavachazomboona mumunda.
• Dhizaini Yehupenyu Hurefu:Zvimiro zvakaita semubatanidzwa wechokwadi muviri, EPDM kana FKM O-mhete, uye yakasimba dhizaini dhizaini zvese zvinopa hupenyu hurefu hwesevhisi. Uyu ndiwo mutsauko pakati pechikamu chekurasa uye pfuma yenguva refu.

Yakagadzirwa zvakanaka, yakanyatsoiswa PVC valve haisi iyo isina simba link; inogara kwenguva refu, corrosion-proof, uye inodhura-inoshanda mhinduro fo
