Wave kuda kumanikidza kuyedza mitsetse yako yePVC ichangobva kuiswa. Iwe unovhara vharafu, asi pfungwa inoshungurudza inooneka: iyo valve inogona kubata kumanikidza kwakanyanya, kana kuti ichatsemuka nekuzadza nzvimbo yebasa?

Kwete, chiyero chekumanikidza bvunzo hachizokuvadza mhando yePVC bhora vharafu. Aya mavharuvhu akagadzirirwa chaizvo kubata kudzvanywa kurwisa bhora rakavharwa. Nekudaro, iwe unofanirwa kudzivirira kamwe kamwe kudzvinyirirwa senge sando yemvura uye kutevedzera nzira dzakaringana.

Izvi zvinonyanya kunetsa, uye chimwe chinhu chandinowanzo jekesera vamwe vangu, kusanganisira timu yaBudi muIndonesia. vatengi vavo vanoda chivimbo chakazara kuti yedumavharuvhuachaita pasi pekunetseka kwe asystem test. Kana vharuvhu yakabudirira kubata kumanikidza, inoratidza kunaka kwevhavha uye kuiswa. Muedzo wakakodzera ndiwo chisimbiso chekupedzisira chekubvumidzwa pabasa rakaitwa nemazvo. Kunzwisisa maitirwo azvo zvakachengeteka kwakakosha pakudzivirira tsaona uye kuve nechokwadi chekuvimbika kwenguva refu kweiyo yese pombi system.

Unogona kumanikidza bvunzo uchipikisa vharafu yebhora?

Iwe unofanirwa kutsaura chikamu chepombi kuti uedze. Kuvhara vharavha yebhora kunoratidzika kunge kune musoro, asi unonetsekana kuti simba racho rinogona kukanganisa zvisimbiso kana kutotsemura muviri wevhavha pachawo.

Ehe, iwe unogona uye unofanirwa kumanikidza bvunzo uchipokana nevhavha yakavharwa yebhora. Magadzirirwo ayo anoita kuti ive yakanaka yekuzviparadzanisa nevamwe. Kumanikidza kunobatsira chaizvo nekusundidzira bhora zvakanyanya muchigaro chepasi, kuvandudza chisimbiso.

Ichi ndicho chimwe chezvakanakira ayebhora vharafudesign. Ngatitarisei zvinoitika mukati. Paunovhara vharafu uye woisa kumanikidza kubva kumusoro kwerukova, simba iroro rinosundira bhora rose rinoyangarara richienda kuzasi kwePTFE (Teflon) chigaro. Simba iri rinodzvanya chigaro, richigadzira chisimbiso chakasarudzika. Ivhavha iri kushandisa chaiyo bvunzo yekumanikidza kuti isimbise pachayo zvakanyanya. Ichi ndicho chikonzero valve yebhora iri nani kune mamwe magadzirirwo, sengegedhi mavharuvhu, nokuda kwechinangwa ichi. Ivhavha yegedhi inogona kukuvadzwa kana yakavharwa uye ichiiswa pasi pekumanikidzwa kwakanyanya. Kuti uedze unobudirira, unongoda kutevedzera mitemo miviri yakapfava: Kutanga, ita shuwa kuti mubato washandurwa yakazara 90 madhigirii kunzvimbo yakavharwa zvizere. Ivhavhavha yakavhurika zvishoma inotadza bvunzo. Chechipiri, pinza muedzo wekuedza (ingave mweya kana mvura) muhurongwa zvishoma nezvishoma uye zvishoma nezvishoma kudzivirira chero kuvhunduka kamwe kamwe.

Unogona kumanikidza kuyedza PVC pombi?

Yako nyowani PVC sisitimu yakanyatsonamirwa uye yakaunganidzwa. Inotaridzika seyakakwana, asi diki, rakavigwa rinodonha mujointi rimwe rinogona kukonzera kukuvara kukuru gare gare. Iwe unoda nzira yekuve 100% chokwadi.

Zvamazvirokwazvo. Dzvinyiriro yekuyedza ichangobva kuisirwa PVC pombi system inhanho isingagone kutaurika kune chero nyanzvi yeplumber. Muedzo uyu unoonesa kutendeseka kwega yega yega yega solvent-welded yekubatanidza uye yakarukwa yekubatanidza isati yavharwa.

Iyi inzira yakakosha yekudzora hunhu. Kutsvaga kudonha madziro asati avharwa kana migero yakazadzwa kumashure iri nyore kugadzirisa. Kuiwana pashure injodzi. Pane nzira mbiri huru dzekuyedzaPVC mapaipi: hydrostatic (mvura)uye pneumatic (mhepo).

Test Method	Zvakanakira	Zvakaipa
Mvura (Hydrostatic)	Yakachengeteka, sezvo mvura isingamanikidzi uye inochengetedza simba shoma. Kudonha kunowanzo kuve nyore kuona.	Inogona kukanganisa. Inoda chitubu chemvura uye nzira yekudzikisa system mushure.
Mhepo (Peneumatic)	Cleaner. Dzimwe nguva unogona kuwana mavuza madiki ayo anogona kusaburitswa nemvura ipapo ipapo.	More ngozi. Mhepo yakamanikidzwa inochengetedza simba rakawanda; kukundikana kunogona kuputika.

Pasinei neyo nzira, mutemo unonyanya kukosha ndewokumirira simenti yekunyungudutsa kuti inyatsopora. Izvi zvinowanzotora maawa makumi maviri nemana, asi unofanira kugara uchitarisa mirairo yemugadziri wesimende. Kudzvanyirira sisitimu nekukurumidza kunoputika majoini. Kudzvanywa kwekuyedza kunofanirwa kunge kuri ka1.5 nguva yesimba rekushanda kwehurongwa, asi usambopfuura chiyero chekumanikidza chechikamu chakaderera-chiyero muhurongwa.

Ko PVC cheki vharafu inogona kuipa here?

Sump yako yepombi inomhanya, asi mwero wemvura haudonhe. Kana kuti pamwe pombi inotenderera ichienda nekudzima nguva dzose. Iwe unofungidzira dambudziko, uye iyo isingaonekwe cheki vharuvhu ndiyo inogona kunge ine mhosva.

Hongu, PVC cheki valve inogona kukundikana. Sezvo chiri chigadziriso chine mativi anofamba, chinogona kunamira nekuda kwemarara, zvisimbiso zvaro zvinogona kupera, kana chitubu chayo chinogona kutyoka, zvichitungamira mukudzokera kumashure.

Tarisa mavharuvhundiwo magamba asina kuimbwa emagadzirirwo epombi akawanda, asi haasi asingafi. Basa ravo nderekubvumira kuyerera munzira imwe chete. Pavanokundikana, zvinenge zvichitungamirira kune dambudziko. Chinonyanya kukonzerakukundikanaimarara. Dombo duku, shizha, kana chidimbu chepurasitiki chinogona kuiswa muvharuvhu, kudzivirira flapper kana bhora kubva pakugara zvakanaka. Izvi zvinobata valve yakavhurika zvishoma, ichibvumira mvura kuti iyerere ichidzokera kumashure. Chimwe chikonzero ndechekupfeka uye kubvaruka. Kupfuura zviuru zvematenderedzwa, chisimbiso chinovharirwa neflapper kana bhora chinogona kupfekwa, zvichiita kudonha kudiki, kunoramba kuripo. Muchitubu-chakabatsirwa cheki valve, chitubu chesimbi chinogona kupera nekufamba kwenguva, kunyanya mumvura ine hutsinye, pakupedzisira ichirasikirwa nekunetsekana kana kuputsika zvachose. Ichi ndicho chikonzero zvakakosha kuisacheki mavharuvhumunzvimbo inosvikika kuti iongororwe uye pakupedzisira inotsiviwa. Ivo chinhu chekugadzirisa, kwete chigarire chekugadzirisa.

Yakawanda sei kumanikidza kunogona kubata PVC bhora vharafu?

Uri kutsanangura mavharuvhu epurojekiti uye ona "150 PSI" padivi. Iwe unofanirwa kuziva kana izvo zvakakwana kune yako application, kana kana iwe uchida inorema-basa sarudzo.

Mavharuvhu ebhora ePVC anowanzo kupihwa 150 PSI yemvura isingavhunduke pa73°F (23°C). Iyi chiyero chekumanikidza inoderera zvakanyanya sezvo tembiricha yemvura inopfuura nepakati pevhavha inowedzera.

Iyo tembiricha yeruzivo ndiyo inonyanya kukosha chikamu chekunzwisisa chiyero chekumanikidza. PVC plastiki inova yakapfava uye inoshanduka-shanduka sezvainopisa. Sezvo inopfava, kukwanisa kwayo kutsungirira kumanikidzwa kunoderedzwa. Uyu ndiwo musimboti wakakosha we thermoplastic pombi masisitimu wandinogara ndichisimbisa naBudi nechikwata chake. Ivo vanofanirwa kutungamira vatengi vavo kuti vatarise tembiricha yekushanda yesystem yavo, kwete kungomanikidza.

Heino gwara rakawanda rekuti tembiricha inobata sei PVC valve's pressure rating:

Fluid Temperature	Anenge Max Pressure Rating
73°F (23°C)	150 PSI (100%)
100°F (38°C)	110 PSI (~73%)
120°F (49°C)	75 PSI (50%)
140°F (60°C)	50 PSI (~33%)

Izwi rekuti "kusavhunduka" rakakosha zvakare. Izvi zvinoreva kuti chiyero chinoshanda kune zvakatsiga, zvinogara zvichimanikidza. Iyo haiverengere nyundo yemvura, iyo inongoerekana yamanikidza spike inokonzerwa nevhavha inovhara nekukurumidza. Iyi spike inogona kudarika 150 PSI nyore uye kukuvadza sisitimu. Nguva dzose shandisa mavharuvhu zvishoma nezvishoma kudzivirira izvi.

Mhedziso

Kuedza kudzvanyirira hakuzokanganisa kunakaPVC bhora vharafukana zvikaitwa nemazvo. Gara uchidzvanya zvishoma nezvishoma, gara mukati mekumanikidza kwevharuvhu uye tembiricha, uye rega simende inonyungudutsa inyatsopora.
