Isahluko 1 - Yintoni ivalvu yebhola?
Ivalvu yebhola yePVC okanye yepolyvinyl chloride yivalvu yeplastiki evaliweyo enebhola ejikelezayo enomngxuma othintela ukuhamba kolwelo ngokujika ibhola ikota yokujika. Zihlala ixesha elide kakhulu, zingabizi kakhulu kwaye zinokusetyenziselwa ukulawula ukuhamba kwamanzi, umoya, iikhemikhali ezibolayo, iiasidi kunye neziseko. Iivalvu zebhola yePVC zinobushushu obuphantsi kakhulu kunye nokumelana noxinzelelo, kodwa zinamandla aphantsi oomatshini. Njengazo zonke iivalvu zebhola, iivalvu zebhola zePVC ziyayeka ukuhamba ngokujikelezisa ibhola ngama-90°.

Umbindi wevalvu yebhola yePVC yibhola ejikelezayo, ebizwa ngokuba yibhola ejikelezayo. Isiqu esingaphezulu kwebhola yindlela ejika ibhola, enokwenziwa ngesandla okanye ngokuzenzekelayo, kuxhomekeke kuyilo lwevalvu. Ivalvu iyavuleka xa isiphatho sihambelana nombhobho kwaye ivale xa isiphatho sithe nkqo kumbhobho.

Iivalvu zebhola zePVC zenziwe ngeplastiki engatshiyo kwaye zinokumelana namaqondo obushushu ukusuka kwi -14°C ukuya kwi -140°C. Zisebenza ngeenjongo ezininzi ezifanayo neevalvu zebhola zemveli, kodwa zilula, zincinci, kulula ukuzifaka, kwaye ziyakwazi ukuziqhelanisa neentlobo ngeentlobo zezicelo.

Isahluko 2 - Iintlobo zeeValvu zeBhola zePVC
Iindidi ezahlukeneyo zeevalvu zebhola zePVC zenzelwe ukuhlangabezana nezicelo ezithile. Zihlulwe ngokwenani leeports, uhlobo lwesihlalo, ukuhlanganiswa komzimba, iipaseji zebhola kunye nobukhulu bebhore. Into ethatha isigqibo ekukhetheni uhlobo lwevalvu yebhola kukusetyenziswa, okugqitywa luxinzelelo, ubungakanani, ubushushu, inani leeports ezifunekayo, izixhobo zokugqibela kunye noqwalaselo.

Iivalvu zebhola zePVC zenziwe ngevinyl, into esetyenziswa kwi-thermoplastic etshintsha iimpawu zomzimba xa ishushu okanye ipholisiwe. Njengazo zonke ii-thermoplastics, iPVC yiplastiki enobuhlobo nokusingqongileyo enokunyibilikiswa kwaye ibunjwe kwakhona amaxesha amaninzi. Ukongeza ekusetyenzisweni ekwenzeni iivalvu zebhola zePVC, iPVC ikwasetyenziswa kakhulu ekuveliseni iipayipi.

ivalvu ezenzekelayo
Ivalvu yebhola yePVC ezenzekelayo inokuba yindlela ezimbini okanye ezintathu. Ine-actuator yomoya okanye yombane enokulawulwa ngesandla nge-remote control okanye ine-spring mechanism. Iivalvu zebhola zePVC ezizisebenzelayo zenzelwe ukuba ziqalise ibhola kwivalvu ukuba ivuleke okanye ivale ukuze ikhulule okanye iyeke ukuhamba kwemidiya kwaye ingasetyenziselwa iintlobo ngeentlobo zemidiya ukusuka emanzini ukuya kwigesi kunye neoyile.

Jonga ivalvu
Iivalvu zokujonga ibhola zePVC zisetyenziswa apho ukuhamba komqolo kunokonakalisa inkqubo okanye kubangele ungcoliseko lwenkqubo yokucoca kunye nokumpompa. Zivalvu yebhola ezenzekelayo ekhulula uxinzelelo kwinkqubo. Iivalvu zokujonga zePVC zii-trunnions ezivala uxinzelelo xa uxinzelelo lufikelela kwinqanaba elithile. Zisetyenziswa kwiinkqubo zokucubungula iikhemikhali, unyango lwamanzi kunye neenkqubo zokupholisa iikhemikhali. Ngokungafaniyo neevalvu zePVC eziqhelekileyo, iivalvu zokujonga azinasiqu okanye isiphatho kwaye zilula kakhulu ekwakheni.

Ivalvu yebhola yePVC ejikelezileyo
Uphawu olukhethekileyo lwevalvu yebhola yePVC ejijekileyo yindlela yayo yokudibanisa, oko kukuthi, iflange. Zinomoya ophezulu kuba zihlala zigcwele. Iivalvu zebhola zePVC ezijijekileyo ziyafumaneka ngeeport ezimbini, ezintathu okanye ezine, zilula kwaye kulula ukuzifaka. Ubukhulu beflange buyahluka ngokuxhomekeke kuxinzelelo olusetyenzisiweyo. Iivalvu zebhola zePVC ezijijekileyo zisebenzisa iglu yokuncamathelisa okanye iibholiti ezineegasket.

Ivalvu yebhola yePVC edadayo
Ngevalvu yebhola yePVC edadayo, ibhola ixhonywa kulwelo kwaye ibanjwe kwindawo yayo yisitulo sevalvu esicinezelweyo. Ishaft inamathele phezulu kwebhola, kwaye ikota yokujika kwesiphatho inika indawo egudileyo ukusuka ekuvulekeni ukuya ekuvalekeni. Njengoko ibhola ijika, icinezelwa kwisihlalo sayo, imisa ukuhamba. Ibhola idada emzimbeni wevalvu, yiyo loo nto ibizwa ngokuba yivalvu.

Ivalvu yeBhola yePVC epheleleyo
Kwiivalvu zebhola zePVC ezizeleyo, ukuvuleka kwebhola kuhambelana nobubanzi bombhobho. Ngenxa yokuba umngxuma okwivalvu ulingana nombhobho, xa ivalvu ivuliwe, ukuhamba komedium akuthintelwanga kwaye akukho kwehla koxinzelelo lwalo naluphi na uhlobo. Iivalvu zebhola zePVC ezizeleyo zithathwa njengeevalvu zokubuyisela amandla kwiinkqubo ezifuna ukwehla koxinzelelo oluphantsi kunye nee-coefficients zokuhamba kwamanzi aphezulu.

Ivalvu Esebenza Ngesandla
Phakathi kweentlobo ngeentlobo zeevalvu zebhola zePVC, ukusebenza ngesandla yeyona ndlela ilula nelula ukuyisebenzisa. Vula ivalvu yebhola yePVC enamacala amabini ngokushukumisa isiphatho sihambelana nombhobho. Ukuze uvale ivalvu, hambisa isiphatho sime nkqo kumbhobho. Ukuvula okanye ukuvala ivalvu kufuna ukujika kwesiphatho ngekota ukuya nakweyiphi na indlela.
