Unoisa vharuvhu itsva yePVC, asi inodonha nguva dzose kubva mushinda. Iye zvino wava nekudonha kunoramba kuripo uko kunokanganisa basa rako uye kunokuvadza mukurumbira wako nemutengi.

Dzivirira kudonha kwemvura nekushandisa tepi yePTFE ine machira mashanu kusvika masere, uchingovhara mativi maviri chete kupfuura neruoko, uye woita shuwa kuti tambo dzacho dzakabatana (NPT neNPT). Kuvhara vharuvhu zvakanyanya ndiko kunokanganisa vharuvhu uye ndiko kunonyanya kuitika pakuiisa.

Ndinowanzo taurira mumwe wangu Mohommad kuti "kukundikana" kwemavharuvhu mazhinji kunenge kuri kukundikana kwekuisa. Kudonhedza kudiki kubva pakubatanidza kwakarukwa kunogona kushungurudza zvikuru, asi chiratidzo chakajeka chekuti danho guru rakatadza kutorwa panguva yekubatanidza. Ndakaona mavharuvhu akanaka achiraswa nekuda kwekukanganisa kuri nyore kwekuisa. Kubatanidza zvakanaka kubva pakutanga kunochengetedza nguva yakawanda, mari, nematambudziko. Ngatitarisei kuti tingazviita sei nemazvo nguva dzese.

Ungamisa sei vharuvhu yebhora kuti isadonhe patambo?

Kudonhedza mvura nguva dzose kubva pakubatanidza kutsva kunonetsa. Wakashandisa sealant, asi kudonhedza mvura hakumire, zvichinonotsa purojekiti yako uye zvichikonzera kukuvara kwemvura.

Dzivisa kubuda kweshinda nekutarisa chisimbiso chako. Shandisa tepi yePTFE yepamusoro-soro, uchiiputira ka5-8 munzira yeshinda. Izvi zvinoita kuti tepi izadze zvakanaka mipata isina kusundirwa kunze panguva yekuisimbisa.

Apa ndipo panotangira nekugumira kudonhedza kweshinda zhinji. Tambo dzakatetepa paPVC fitting hadzina kugadzirwa kuti dzigadzire chisimbiso dzoga. Basa radzo nderekugadzira simba remuchina. Chisimbiso chaicho chinogadzirwa nechisimbiso cheshinda. Tepi yePTFE, inonziwo tepi yeTeflon, ndiyo sarudzo inonyanya kushandiswa uye inoshanda. Chinhu chikuru chiri mukushandisa. Kutanga, iva nechokwadi chekuti shinda dzechirume dzakachena uye dzakaoma zvachose. Tanga kuputira shinda yechipiri kubva kumagumo. Izvi zvakakosha kudzivirira chero tepi kuti isachekwe yoiswa mupombi, uko inogona kuvhara sisitimu. Unofanira kuputira tepi uchitenderedza wachi, nenzira imwe chete yauchasimbisa fitting. Kana ukaiputira uchitenderedza wachi, chiito chiri nyore chekusvuura fitting chichaita kuti tepi iungane uye ivhurike. Kune fittings dzakajairwa kubva pa1/2″ kusvika 1″, 5 kusvika ku8 full wraps ndiyo huwandu hwakakodzera. Dhonza tepi yakasimba paunenge uchiputira kuitira kuti inyure mumipata yeshinda. Unofanira kunge uchiri kukwanisa kuona chimiro cheshinda kuburikidza netepi.

Ungadzivirira sei kubuda kwevharuvhu usati waisa?

Wava kuda kubatanidza vharuvhu, asi shinda dzinonzwa dzisina kumira zvakanaka kana ukaedza. Kusateerera manzwiro aya kunogona kutungamira kune kubatana kunobvisa kana kudonhedza mvura zvisinei nezvaunoita.

Dzivisa kudonha kwemvura nekusimbisa kuti tambo dzako dzakabatana usati watombobata chinovhara. Nyika zhinji dzinoshandisa BSPT, nepo North America ichishandisa NPT. Dzinotaridzika zvakafanana asi hadzienderane zvachose uye dzinogara dzichidonha.

Iyi ndiyo nzira inonyanya kukosha, uye kuisiya kunovimbisa kukundikana. Sezvatakakurukura naMohommad neni pamusika weBangladesh, unowanzoona kuti mitemo yeNPT neBSPT iripo. Hazvichinjiki.

• NPT (National Pipe Taper):Tambo iyi ine kona yemadhigirii makumi matanhatu.
• BSPT (British Standard Pipe Taper):Tambo iyi ine kona ye55-degree.

Kumanikidza NPT yemurume kuisa muvharuvhu yeBSPT yemukadzi inzira yekukonzera njodzi. Makona akasiyana anoita kuti asunge uye apfuure shinda. Kubatana kwacho kunogona kunzwa kwakasimba, asi uri kungokuvadza purasitiki uye kugadzira nzira inodonha isingagone kugadziriswa nechivharo. Usati waisa, bata tambo yemurume kuisa pavharuvhu yemukadzi. Tsvaga zviratidzo. PaPntek, tinoisa zviratidzo zvakajeka mumavharuvhu edu nerudzi rweshinda. Kana pasina zviratidzo, edza kuabatanidza neruoko kwekamwe chete kana kaviri. Kana uchinzwa kuramba kwakanyanya kana kuzununguka, mira ipapo ipapo. Hazvina kunyatsoenderana. Kuongorora uku kwemasekonzi mashanu kunodzivirira imwe yezvikanganiso zvakanyanya uye zvinogoneka kudzivirira kuisa.

Sei kusimbisa zvakanyanya iriyo nzira yakaipa yekurapa vharuvhu iri kubuda?

Vharuvhu yako iri kudonha mvura, saka unotora chipanera chikuru kuti uchitenderedze zvakare. Unonzwa kutsemuka kwakapinza, uye zvino kudonha kudiki kwave kukundikana kukuru, kusingagadzirisike.

Kusunga zvakanyanya ndicho chikonzero chikuru chekukundikana kwevharuvhu yePVC. Kushanda kwetambo yemurume yakatetepa kunoparadzanisa chiteshi chePVC chevakadzi. Torque chaiyo inongobatisa ruoko, wobva watenderedza kamwe chete kana kaviri uchishandisa chipanera.

Ipfungwa yechisikigo: kana chimwe chinhu chichidonha, chisimbise zvakanyanya.Mavharuvhu ePVC, izvi hazvina kunaka. Kusiyana nesimbi, PVC ipurasitiki ine thermoplastic isina kusimba zvakanyanya. Kana ukasunga fitting ine tapered (kunyanya yesimbi) muPVC port yechikadzi, unenge uchipinza wedge mupurasitiki. Izvi zvinogadzira kumanikidzwa kukuru kwekunze, kunozivikanwa sehoop stress. Hazvidi simba rakawanda kuti zvipfuure simba rekudhonza rePVC. Izvi zvinokonzera kutsemuka kwebvudzi pasi peshinda, iyo inozopararira pasi pekumanikidzwa kwesystem. Mutemo watinodzidzisa uri nyore uye wakazara:Kubata nemaoko pamwe nekutendeuka kamwe chete kusvika kaviri.Ndizvozvo chete. Shandisa chipanera chetambo kana uchikwanisa kudzivirira kuisa simba pavharuvhu. Chisimbiso chinogadzirwa netepi yePTFE inodzvanywa mumaburi eshinda, kwete nekupwanya purasitiki kuti ipinde. Kana ikadonha mushure mekusunga zvakanaka, dambudziko harisi rekusimba. Unofanira kubvisa kubatana uye kutarisa zvimwe zvinhu zvakaita seshinda dzisina kuenderana kana tepi isina kukwana.

Ndezvipi zvitatu zvinowanzo kundikana kubva pakuiswa zvisina kunaka?

Unosangana nedambudziko revharuvhu panzvimbo yebasa. Unoramba uchichinja zvikamu zvebasa, asi matambudziko acho anoramba aripo, zvichikutorera nguva, mari, uye zvichideredza kuvimba kwemutengi wako nebasa rako.

Zvinhu zvitatu zvinonyanya kukundikana pakuisa zvinosanganisira: mapombi akatsemuka nekuda kwekusimba zvakanyanya; tambo dzinoramba dzichibuda nekuda kwekushandisa tambo dzeNPT/BSPT dzisina kuenderana; uye kukuvara kwechisimbiso chemukati nekuda kwemarara anopinda muvharuvhu panguva yekuisa.

Kunzwisisa kukundikana uku kutatu kunokubatsira kugadzira runyorwa rwepfungwa rwekuisa kwega kwega. Kana vharuvhu ine tambo ikakundikana, inenge iri imwe yezvikonzero izvi.

Kukundikana kwechitatu ikoko kunowanzo furatirwa. Kana vharuvhu yebhora ikaoma kutenderedza kana kudonha kana yavharwa, zvinogona kunge zvichikonzerwa nekuti chidimbu chidiki chetsvina chakasukwa muvharuvhu. Kana bhora rikavhara pachinhu ichi chakaoma, rinogona kukanda pamusoro pebhora repurasitiki zvachose kana kukuvadza zvigaro zvePTFE zvakapfava. Izvi zvinogadzira nzira yekudonha isingaperi nepakati pevharuvhu. Gara uchichengeta mavharuvhu ako matsva mupakeji yawo kusvika panguva yekuiswa, uye gara uchibvisa mitsetse usati waisa. Masekondi mashoma ekutarisira anodzivirira matambudziko makuru gare gare.

Mhedziso

Dzivirira kubuda kweshinda nekubatanidza shinda, kushandisa sealant nemazvo, uye kudzivirira kusimba zvakanyanya. Kuisa zvakanaka ndicho chakavanzika chekushanda kwakavimbika, kwenguva refu, uye kusina kubuda kwemvura.Vharuvhu yebhora yePVChurongwa.
