Ingcaciso yeMveliso

Iimpawu zeeMveliso

1)Ukuthobela imigangatho yamanzi okusela.

I-2) Izinto eziphathekayo zihamba ngokuguqulwa kwe-nano ukuphucula ukunyanzeliswa koxinzelelo lwemveliso kunye nokuchasana kwempembelelo.

3) Ukongeza i-anti-UV absorbers kunye ne-antioxidants kwimathiriyeli ekrwada ukuphucula ukuxhathisa imozulu yemveliso kunye nokumelana nokwaluphala.

4)Inokufakwa ngokuthe tye okanye ngokuthe nkqo.

Iimveliso zevalvu yokuqinisekisa umanyano lwePVC ziyi-asidi, ialkali, kunye nobushushu obuphezulu obuxhathisayo, isetyenziswa kakhulu kumashishini ahlukeneyo afana neshishini lemichiza, unyango lwamanzi amdaka, ukwakhiwa kweplanti yamandla, umgca wemveliso wePCB, iasidi enzima kunye neshishini lealkali, kunye nobunjineli bokucoca amanzi.

I-hemisphere entsha enoyilo lwesikhokelo sikaloliwe iqinisekisa ukuba ihemisphere ayithambeki kwaye inesiphumo esihle sokumisa amanzi.

Iinxalenye zokudibanisa kumacala omabini emveliso ziyilwe kwifom edibeneyo eguquguqukayo, ekulungele ukufakela kunye nokutshintshwa.

Imveliso yimveliso yeplastiki ngokupheleleyo ngaphandle kwezixhobo zetsimbi.

Ivalve yonyawo isetyenziselwa ntoni?

Ivalve yonyawo sisixhobo esisetyenziselwa ukulawula indlela yokuhamba kolwelo okanye irhasi, edla ngokufakwa ezantsi kombhobho okanye inqanawa. Inokuthintela i-medium ukuba ihambe ngasemva kwaye igcine ukuzinza kwenkqubo eqinile. Kwintsimi yobunjineli bokwakha, i-valve ephantsi isetyenziswa ngokuqhelekileyo kunyango lwamanzi, ukucocwa kwamanzi amdaka, inkqubo yokubonelela ngamanzi, njl.

Yintoni icandelo levalvu yonyawo?

ibandakanya umzimba wevalve, ibhonethi, intwasahlobo, ipiston kunye neringi yokutywina. Ulwakhiwo lwalo luhlangene kwaye luqinile, kwaye lunokumelana noxinzelelo olukhulu kunye nesantya sokuhamba. Ngelo xesha, i-valve engezantsi nayo ineempawu zokunganyangeki kunye nokuxhatshazwa kwe-abrasion, ezifanelekileyo kwiindawo ezahlukeneyo ezibuhlungu.

Isebenza njani ivalve yonyawo?

Xa isiphakathi sisuka kumbhobho okanye isikhongozeli sokungena, ivalve esezantsi iyavuleka, ivumela isiphakathi ukuba sidlule ngokukhululekileyo. Kwaye xa i-medium igeleza ngasemva, i-valve ephantsi ivala, ikhusela i-medium ukuba ihambe ngasemva. Oku kuphunyezwa nge-valve esezantsi entwasahlobo yangaphakathi kunye nepiston. Xa umkhombandlela wokuhamba ophakathi uchasene nolwalathiso olusekwe yivalve esezantsi, umthombo uya kutyhala ipiston ukuba ivale umlomo wevalve esezantsi, ngaloo ndlela ithintele ukubuya umva.

Yintoni umahluko phakathi kwevalve yonyawo kunye nevalve yokukhangela?

I-1)Iivalve ezisezantsi kunye ne-check valves ziyahluka ekusebenzeni.

Iivalvu ezisezantsi zisetyenziswa ikakhulu ukulawula ukuhamba kolwelo ngaphakathi nangaphandle kombhobho nokuthintela ulwelo olukumbhobho ukuba lungabuyeli ngasemva; ngelixa iivalvu zokukhangela zisetyenziselwa ikakhulu ukuthintela ulwelo ukuba lungahambi ngasemva kwaye lukhusele umbhobho kunye nezixhobo.

Iivalve ezisezantsi kunye neevalve zokukhangela zineendlela ezahlukeneyo zoyilo. Umsebenzi oyintloko we-valve ephantsi kukuthintela ulwelo olusembhobho ukuba lungabuyeli kumthombo wamanzi okanye kumthombo, osetyenziselwa ukuqinisekisa ukunikezelwa kwamanzi okuqhubekayo kunye nokukhusela izixhobo zempompo.

Indima ephambili yevalve yokutshekisha kukuthintela ukuphuma ngasemva okanye ukubuya umva kolwelo kumbhobho, ukuqinisekisa ukuhamba kwendlela enye yombhobho, kodwa ingasetyenziselwa ukuthomalalisa impembelelo yehamile yamanzi.

2)Iivalve ezisezantsi kunye neevalufa zokukhangela zisebenza ngokwahlukileyo.

Ivalve esezantsi luhlobo lwevalve yomxhuzulane, ukuvulwa nokuvalwa kwayo kuchatshazelwa luxinzelelo kunye nobunzima bolwelo olukumbhobho, xa kukho ulwelo olungena kumbhobho, ivalve yevalve iya kutyhala ivuleke lulwelo, ukuze ukuqonda ukuhamba kakuhle kwamanzi. Xa ulwelo luyekile ukuhamba okanye lungena kumbhobho ukusuka ezantsi, i-valve diaphragm iya kuzivala ngokuzenzekelayo ukunqanda ulwelo ukuba lungabuyeli ngasemva.

Iivalvu zokukhangela, kwelinye icala, ziivalvu zoomatshini ezivula kwaye zivale phantsi kwefuthe loxinzelelo lolwelo kumbhobho kunye ne-spring elasticity ukuqinisekisa ukuhamba kolwelo olulodwa. Xa ulwelo olukumbhobho luhamba ngendlela emiselwe kwangaphambili, i-valve flap iya kutyhala ivuleke, kwaye ivalve yokukhangela ikwimeko evulekileyo; xa i-liquid ihamba kwicala elichaseneyo, i-valve flap iya kuvalwa, kwaye i-valve yokukhangela ikwimeko evaliweyo.
