Ucinga ukuba ivalve yakho ivumela ukuhamba okuphezulu, kodwa inkqubo yakho ayisebenzi kakuhle. Ivalve oyikhethileyo inokuminxa umgca, inciphisa ngokuzolileyo uxinzelelo kunye nokusebenza kakuhle ngaphandle kokwazi ukuba kutheni.
Ayizizo zonke iivalvu zebhola zePVC ezigcwele izibuko. Uninzi lwezibuko eziqhelekileyo (ezikwabizwa ngokuba yizibuko elincitshisiweyo) ukugcina ixabiso kunye nendawo. Ivalve yezibuko epheleleyo inomngxuma olingana nombhobho wokuhamba okungathintelwanga ngokupheleleyo.
Le yinkcukacha ebalulekileyo kuyilo lwenkqubo, kwaye yinto endiyixoxa rhoqo namaqabane am, kuquka neqela likaBudi eIndonesia. Ukhetho phakathi kwezibuko elipheleleyo kunye nezibuko elisemgangathweni lichaphazela ngokuthe ngqo ukusebenza kwenkqubo. Kubathengi beBudi abaziikontraka, ukufumana eli lungelo kuthetha umahluko phakathi kwenkqubo esebenza kakhulu kunye nengafikeleliyo kulindelekileyo. Ngokuqonda lo mahluko, banokukhetha ivalve yePntek egqibeleleyo kuwo wonke umsebenzi, ukuqinisekisa ukwaneliseka kwabathengi kunye nokwakha igama labo lomsebenzi osemgangathweni.
Ngaba ivalve yebhola yivalve yezibuko epheleleyo?
Udinga ukuhamba okuphezulu kwenkqubo yakho yempompo entsha. Kodwa emva kofakelo, ukusebenza kuyadanisa, kwaye ukrokrela ibhotile kwindawo ethile emgceni, mhlawumbi ukusuka kwivalve yokuvala oyisebenzisayo.
Ivalve yebhola inokuba lizibuko elipheleleyo okanye izibuko eliqhelekileyo. Umbhobho wevalve egcweleyo (umngxuma) uhambelana nedayamitha yangaphakathi yombhobho kuthintelo lokuhamba. Izibuko elisemgangathweni linye ubukhulu bombhobho omncinci.
Igama elithile "izibuko eligcweleyo"(okanye i-bore egcweleyo) luphawu oluthile loyilo, hayi umgangatho wendalo yonke wazo zonke iivalvu zebhola. Ukwenza lo mahluko ngundoqo kukhetho olufanelekileyo lwevalvu.Ivalve yesivalo esigcweleyo yenzelwe ukusebenza kakuhle okukhulu. Umngxuma okwibhola ukhulu kakhulu ukuze ulingane nobubanzi bangaphakathi bombhobho oqhagamshelwe kuwo.ivelufa yezibuko esemgangathweni, ngokuchaseneyo, unomngxuma onobungakanani obuncinci obuncinci kunombhobho. Oku kudala uthintelo oluncinci.
Ngoko, ufanele uyisebenzise nini nganye? Nasi isikhokelo esilula endisinika amaqabane ethu.
| Uphawu | I-Valve yePort epheleleyo | I-Standard Port (Encitshisiweyo) iValve |
|---|---|---|
| Ubungakanani Bore | Kuyafana nedayamitha yangaphakathi yombhobho | Isayizi enye encinci kune-ID yombhobho |
| Uthintelo lokuqukuqela | Ngokusisiseko akukho nanye | Isithintelo esincinci |
| Ukwehla koxinzelelo | Isezantsi kakhulu | Ngaphezulu kancinci |
| Iindleko kunye nobukhulu | Ephakamileyo & Enkulu | Uqoqosho oluthe kratya & luhlangeneyo |
| Eyona meko yokusetyenziswa | Imigca ephambili, iziphumo zempompo, iinkqubo eziphezulu zokuhamba | Ukuvalwa ngokubanzi, imigca yesebe, apho ukuhamba kungabalulekanga |
Kwiinkqubo ezininzi zemihla ngemihla, njengomgca wesebe kwi-sink okanye kwindlu yangasese, i-valve ye-port eqhelekileyo ilungile kwaye ibiza kakhulu. Kodwa kumgca omkhulu wamanzi okanye ukukhutshwa kwempompo, i-valve ye-port epheleleyo ibalulekile ukugcina uxinzelelo kunye nokuhamba.
Yintoni ivalve yebhola yePVC?
Udinga indlela elula nethembekileyo yokumisa amanzi. Iivalvu zesango ezidala zaziwa ngokubamba okanye zivuze xa uzivala, kwaye ufuna ivalve esebenza ngalo lonke ixesha.
Ivalve yebhola yePVC yivalve yokuvala esebenzisa ibhola ejikelezayo enomngxuma kuyo. Ukukhawuleza kwekota-ukujika kwesiphatho kulungelelanisa umngxuma kunye nombhobho ukuwuvula okanye ukuwujikela ngokuchasene nokuhamba ukuwuvala.
IIvalve yebhola yePVCidume ngobulula bayo obuqaqambileyo kunye nokuthembeka okumangalisayo. Makhe sijonge iindawo zayo eziphambili. Iqala ngomzimba ozinzileyo wePVC ogcina yonke into kunye. Ngaphakathi kuhlala intliziyo yevalvu: ibhola yePVC engqukuva enomngxuma ochanekileyo, okanye "ubhobhozo," embindini. Le bhola iphumla phakathi kwezangqa ezimbini ezibizwa ngokuba zizihlalo, ezenziwe ngazoI-PTFE (isixhobo esidume ngegama lebrendi, iTeflon). Ezi zihlalo zenza itywina elingangeni manzi ebholeni. Isiqu sidibanisa isiphatho esingaphandle nebhola engaphakathi. Xa uguqula isibambo se-90 degrees, isiqu sijikeleza ibhola. Indawo yokuphatha ihlala ikuxelela ukuba ivalve ivuliwe okanye ivaliwe. Ukuba isibambo sihambelana nombhobho, sivulekile. Ukuba i-perpendicular, ivaliwe. Olu yilo lulula, lusebenzayo lunamalungu ambalwa kakhulu ashukumayo, yiyo loo nto ithenjwa kwizicelo ezingenakubalwa kwihlabathi liphela.
Yintoni umahluko phakathi kwezibuko le-L kunye neevalve zebhola ze-T?
Iprojekthi yakho ifuna ukuba ujike amanzi, ungayiyeki nje. Uceba inethiwekhi eyinkimbinkimbi yeepayipi kunye neevalvu, kodwa uvakalelwa kukuba kufuneka kube nesisombululo esilula, esisebenzayo.
Izibuko le-L kunye ne-T libhekiselele kwimilo yebhore kwivalve yebhola yeendlela ezi-3. Izibuko le-L liyaphambukisa ukuhamba phakathi kweendlela ezimbini, ngelixa i-T port inokuphambukisa, ixube, okanye ithumele ukuhamba ngokuthe ngqo.
Xa sithetha ngezibuko ze-L kunye ne-T, sihamba ngaphaya kwee-valve ezilula / zokuvala kunye nokungenaiivalvu ezininzi. Ezi ziyilelwe ukulawula indlela yokuhamba. Ziluncedo kakhulu kwaye zinokutshintsha iivalvu ezininzi eziqhelekileyo, ukonga indawo kunye nemali.
Iivalvu ze-L-Port
Ivalve yesibuko se-L inombhobho omile okwe "L." Inendawo yokungena ephakathi kunye neendawo ezimbini zokuphuma (okanye ezimbini zokungena kunye nenye yokuphuma). Ngesiphatho kwindawo enye, ukuhamba kuhamba ukusuka embindini ukuya ekhohlo. Ngokujika kwe-90-degree, ukuhamba kuhamba ukusuka embindini ukuya ekunene. Indawo yesithathu ivalela konke ukuhamba. Ayinakuqhagamshela omathathu amazibuko kanye. Umsebenzi wayo kukuguqula ngokupheleleyo.
Iivalve zeT-Port
A Ivalve ye-T-portiyaguquguquka ngakumbi. Umbhobho wayo umile okwe "T." Inokwenza yonke into enokwenziwa yi-L-port. Nangona kunjalo, inendawo yokuphatha eyongezelelweyo evumela ukuhamba ngokuthe ngqo kumazibuko amabini achaseneyo, njengevalve yebhola esemgangathweni. Kwezinye iindawo, inokudibanisa onke amazibuko amathathu ngaxeshanye, nto leyo eyenza ukuba ilungele ukuxuba ulwelo ezimbini kwindawo enye.
| Uhlobo lwePort | Umsebenzi ongundoqo | Qhagamshela Omathathu amaZibuko? | I-Common Use Case |
|---|---|---|---|
| I-L-Port | Ukuphambukisa | No | Ukutshintsha phakathi kwamatanki amabini okanye iimpompo ezimbini. |
| T-Port | Ukuphambukisa okanye ukuxuba | Ewe | Ukuxuba amanzi ashushu nabandayo; ukubonelela ngokudlula. |
Ngaba iivalvu zeplagi zigcwele?
Ubona olunye uhlobo lwevalve yekota ebizwa ngokuba yivalve yeplagi. Ijongeka ifana nevalve yebhola, kodwa awuqinisekanga ukuba isebenza njani ngokwendlela yokuhamba okanye ukuthembeka kwexesha elide.
Njengeevalve zebhola, iivalve zeplagi zinokuba yi-port epheleleyo okanye i-port encitshisiweyo. Nangona kunjalo, uyilo lwazo ludala ukukhuhlana okungaphezulu, kubenza kube nzima ukujika kwaye kunokwenzeka ukuba babambelele ekuhambeni kwexesha kunevalve yebhola.
Olu luthelekiso olunika umdla kuba lugxininisa isizathuiivalve zebholaziye zaduma kakhulu kushishino. Aivalve yeplagiisebenzisa cylindrical okanye tapered iplagi kunye umngxuma kuyo. Ivalve yebhola isebenzisa ingqukuva. Zombini zinokuthi ziyilwe ngokuvula izibuko ngokupheleleyo, ngoko ke, ziyafana. Umahluko ophambili yindlela ezisebenza ngayo. Iplagi kwivalve yeplagi inommandla omkhulu kakhulu othe gqolo ukudibana nomzimba wevalvu okanye iliner. Oku kudala ukungqubana okuninzi, okuthetha ukuba kufuna amandla angaphezulu (torque) ukujika. Oku kukhuhlana kuphezulu kwenza ukuba kube lula ukubamba ukuba ayisetyenziswa rhoqo. Ivalve yebhola, kwelinye icala, itywina ngezihlalo zePTFE ezincinci, ezijoliswe kuzo. Indawo yoqhagamshelwano incinci kakhulu, ibangela ukukhuhlana okuphantsi kunye nokusebenza kakuhle. Kwi-Pntek, sigxininisa kuyilo lwevalve yebhola kuba inika ukutywinwa okuphezulu ngomzamo omncinci kunye nokuthembeka okukhulu kwexesha elide.
Ukuqukumbela
Ayizizo zonke iivalvu zebhola zePVC ezigcwele izibuko. Soloko ukhetha izibuko elipheleleyo leesistim zokuqukuqela okuphezulu kunye nezibuko eziqhelekileyo zokuvalwa ngokubanzi ukwenza umsebenzi kunye neendleko kwiimfuno zakho ezithile.
