Isahluko 1 - Yintoni ivalve yebhola?
Ivalve yebhola ye-PVC okanye i-polyvinyl chloride yivalve yeplastiki evuliweyo enebhola ejikelezayo enomngxuma omisa ukuqukuqela kwamanzi ngokujika ibhola kwikota. Zomelele ngokugqithisileyo, azibizi mali ininzi kwaye zingasetyenziselwa ukulawula ukuhamba kwamanzi, umoya, iikhemikhali ezonakalisayo, iiasidi kunye neziseko. Iivalvu zebhola zePVC zineqondo lobushushu elisezantsi kunye nokumelana noxinzelelo, kodwa amandla aphantsi oomatshini. Njengazo zonke iivalvu zebhola, iivalvu zebhola zePVC zimisa ukuhamba ngokujikeleza ibhola ngama-90°.

Undoqo wevalve yebhola yePVC yibhola ejikelezayo, ebizwa ngokuba yibhola ejikelezayo. Isiqu esiphezulu sebhola yindlela ejika ibhola, enokwenziwa ngesandla okanye ngokuzenzekelayo, kuxhomekeke kuyilo lwevalve. I-valve ivula xa isibambo sihambelana nombhobho kwaye sivale xa isibambo si-perpendicular kumbhobho.

Iivalvu zebhola zePVC zenziwe ngeplastiki engatshiyo kwaye ziyakwazi ukumelana namaqondo obushushu ukusuka ku -14°C ukuya kwi -140°C. Bakhonza iinjongo ezininzi ezifanayo njengeevalvu zebhola zendabuko, kodwa zikhaphukhaphu, zihlangene, zilula ukuzifaka, kwaye ziyakwazi ukuziqhelanisa noluhlu olubanzi lwezicelo.

Isahluko 2 - Iindidi zePVC Ball Valves
Iindidi ezahlukeneyo zeevalvu zebhola zePVC ziyilelwe ukuhlangabezana nezicelo ezithile. Zihlelwa ngenani lamazibuko, uhlobo lwesihlalo, ukuhlanganisana komzimba, iipaseji zebhola kunye nobukhulu bebhore. Isigqibo ekukhetheni uhlobo lwevalve yebhola sisicelo, esichongwa ngoxinzelelo, ubungakanani, ubushushu, inani lamachweba afunekayo, ukufakwa kokuphela kunye noqwalaselo.

Iivalve zebhola ze-PVC zenziwe nge-vinyl, i-thermoplastic material etshintsha iimpawu zomzimba xa ishushu okanye ipholile. Njengazo zonke i-thermoplastics, i-PVC yiplastiki ehambelana nokusingqongileyo enokuthi inyibilike kwaye iguqulwe kaninzi. Ukongeza ekusetyenzisweni kokwenziwa kweevalvu zebhola ze-PVC, i-PVC ikwasetyenziswa ngokubanzi kwimveliso yemibhobho.

ivalve ezenzekelayo
Ivalve yebhola ye-PVC ezenzekelayo inokuba macala amabini okanye amathathu. Bane-actuator ye-pneumatic okanye yombane enokulawulwa ngesandla kunye ne-remote control okanye ibe ne-spring mechanism. Iivalve zebhola ze-PVC ezizisebenzelayo zenzelwe ukuqalisa ibhola kwivalve ukuvula okanye ukuvala ukukhulula okanye ukumisa ukuhamba kweendaba kwaye ingasetyenziselwa iindidi ezininzi zeendaba ukusuka emanzini ukuya kwigesi kunye neoli.

Jonga ivalve
Iivalve ze-PVC zokujonga ibhola zisetyenziselwa apho ukuhamba ngasemva kungonakalisa inkqubo okanye kubangele ukungcoliseka kokucoca kunye nenkqubo yokupompa. Ziyivalve yebhola ezenzekelayo ekhulula uxinzelelo kwinkqubo. Iivalvu ze-PVC zokujonga zii-trunnions ezivala ngoxinzelelo xa uxinzelelo lufikelela kwinqanaba elithile. Zisetyenziselwa ukusetyenzwa kweekhemikhali, unyango lwamanzi kunye neenkqubo zokupholisa iikhemikhali. Ngokungafaniyo neevalvu zePVC eziqhelekileyo, iivalve zokujonga azinasiqu okanye umqheba kwaye zilula ngolwakhiwo.

Ivalve yeBhola yePVC eneFlanged
Isici esiyingqayizivele se-valve yebhola ye-PVC ene-flanged yindlela yokudibanisa, oko kukuthi, i-flange. Zinokuhamba okuphezulu ngenxa yokuba zihlala zigcwele. Iivalvu zebhola zePVC ezineFlanged ziyafumaneka ngamazibuko amabini, amathathu okanye amane, zikhaphukhaphu kwaye kulula ukuzifaka. Ubunzima be-flange buyahluka ngokuxhomekeke kuxinzelelo olusetyenzisiweyo. Iivalvu zebhola ezinamaphiko zePVC zisebenzisa iglu encamathelayo okanye iibholiti ezinegaskets.

Ivalve yeBhola yePVC edadayo
Ngevalve yebhola ye-PVC edadayo, ibhola ixhonywe kulwelo kwaye igcinwe endaweni yayo sisitulo sevalve esicinezelweyo. I-shaft ifakwe phezulu kwebhola, kwaye ikota yekota yokujika inika indawo egudileyo ukusuka evulekileyo ukuya evaliweyo. Njengoko ibhola ijika, icinezelwe kwisitulo sayo, imisa ukuhamba. Ibhola idada kumzimba wevalvu, kungoko kubizwa igama levalve.

Full Bore PVC Ball Valve
Ukufumana iivalve zebhola zePVC ezigcweleyo, ukuvuleka kwebhola kuhambelana nobubanzi bombhobho. Ngenxa yokuba umngxuma kwi-valve ubungakanani obufana nombhobho, xa i-valve ivulekile, ukuhamba kwe-medium akuthinteli kwaye akukho xinzelelo loxinzelelo lwaluphi na uhlobo. Iivalvu zebhola ze-PVC ezigcweleyo zibhekwa njengeevalve zokubuyisela kwiinkqubo ezifuna ukuhla koxinzelelo oluphantsi kunye ne-coefficients yokuhamba okuphezulu.

Ivalve eSebenzayo ngesandla
Phakathi kweentlobo ngeentlobo zeevalvu zebhola zePVC, ukusebenza ngesandla yeyona nto ilula kwaye kulula ukuyisebenzisa. Vula ivalve yebhola ye-PVC yeendlela ezimbini ngokuhambisa umqheba ngokuhambelana nombhobho. Ukuvala i-valve, hambisa i-handle perpendicular kumbhobho. Ukuvula okanye ukuvala ivalve kufuna ukujika kwekota yesibambo kulo naliphi na icala.
