Ivalve yebhabhathane

Ivalve yebhabhathane yeyodidi lwevalvu yekota. Iivalvu zekota ziquka iindidi zevalvu ezinokuvulwa okanye zivalwe ngokujika isikhondo sibe yikota. Kwiiivalve butterfly, kukho idiski eqhotyoshelwe kwisiqu. Xa intonga ijikeleza, ijikeleza i-disc ngekota, ibangela ukuba i-disc iwele i-perpendicular kumanzi kwaye iyeke ukuhamba. Ukubuyisela ukuhamba, i-stem ijikeleza i-disc ibuyele kwindawo yayo yokuqala, kude nokuhamba.

Iivalve zebhabhathane zithandwa kakhulu kuba kulula ukuzifaka, azibizi, kwaye zifumaneka phantse kuzo zonke iisayizi. Ezi ngokuqhelekileyo zisetyenziselwa iinkonzo zokulawula kunye neenjongo zokutshintsha.

Ukusetyenziswa kwevalve yebhabhathane

Iivalve zebhabhathane zibalulekile kwiinkqubo kunye nokusebenza kumashishini amaninzi awohlukeneyo. Oku kungenxa yobukhulu boluhlu kunye nokukwazi ukulawula ukuhamba kwamanzi, igesi kunye nodaka. Iivalve zebhabhathane azikwazi kuphela ukumisa okanye ukuqala ukuhamba, kodwa zinciphisa okanye zinciphise ukuhamba njengoko zifunwa xa zivulwa ngokuyinxenye.

Abathengi abavela kumashishini amaninzi bathenga iivalve zebhabhathane, kubandakanywa nalawo akwimimandla yokulungiswa kokutya (ulwelo), izityalo zamanzi, ukunkcenkceshela, ukuveliswa kwemibhobho, ukuveliswa kwemizi-mveliso, iinkqubo zokufudumeza kunye nokuthuthwa kweekhemikhali.

Nangona iivalve zebhabhathane zinezicelo ezininzi ezahlukeneyo ezinokwenzeka, ezinye izicelo ezithile zibandakanya i-vacuum, ukubuyiswa kweoyile, inkonzo yomoya ecinezelekileyo, ukupholisa umoya kunye namanzi, i-HVAC, inkonzo yodaka, inkonzo yoxinzelelo oluphezulu lwamanzi, inkonzo yamanzi obushushu obuphezulu, inkonzo ye-steam kunye nokukhusela umlilo.

Ngenxa yokwahluka koyilo kunye nezixhobo, iivalve zebhabhathane zineendlela ezininzi zokusetyenziswa. Ezi zinokufakwa kuyo nayiphi na imibhobho, ukusuka emanzini acocekileyo ukuya kumanzi okugaya okanye i-slurry. Ezi ziqhele ukusetyenziswa kwiinkqubo zodaka okanye udaka, iinkonzo zokufunxa, iinkonzo zomphunga, amanzi okupholisa, umoya, okanye ukusetyenziswa kwerhasi.

Izinto eziluncedo kunye nokungonakali kwevalve yebhabhathane

Iivalve zebhabhathanebonelela abasebenzisi ngeenzuzo ezininzi. Okokuqala, banoyilo oludibeneyo. Ngenxa yolu yilo ludityanisiweyo, zifuna indawo yokusebenza encinci kunezinye iivalvu ezininzi. Okwesibini, iindleko zokugcinwa kwevalve yebhabhathane ziphantsi kakhulu. Okwesibini, babonelela ngomgangatho ophezulu wokuxinana kwezithuthi. Kwakhona, azivuzi, kodwa zinokuvuleka lula xa zifuneka. Enye inzuzo yevalve yebhabhathane lixabiso layo eliphantsi.

Izinto eziluncedo zevalve yebhabhathane

1. Ngenxa yobuncinci babo kunye noyilo oludibeneyo, iindleko zokufakela ziphantsi kakhulu.

2. Ezi zivalo zithatha indawo encinci kakhulu xa kuthelekiswa nezinye iivalvu.

3. I-Automatic actuation yenza ukuba ikhawuleze kwaye isebenze ngakumbi kunezinye iivalve.

4. Ngenxa yoyilo lweediski ezininzi kunye neenxalenye ezincinci ezihambayo, zifuna ukugcinwa okuncinci, oko kunciphisa kakhulu imozulu.

5. Izixhobo zokuhlala ezahlukeneyo zenza kube lula ukuzisebenzisa kuzo zonke iintlobo zeendawo ezisingqongileyo, nkqu neendawo ezirhabaxa.

6. Iivalve zebhabhathane zifuna imathiriyeli encinci, kulula ukuyila kunye nokuveliswa, kwaye ngokuqhelekileyo zibiza kakhulu kunezinye iintlobo zeevalvu.

7. Iivalve zebhabhathane zingasetyenziswa kwiintlobo ngeentlobo zezicelo, kubandakanywa nofakelo oluphantsi komhlaba.

Ukungalungi kwevalve yebhabhathane

Ngokwenene, izinto ezingalunganga zeevalvu zebhabhathane zigqwesa iingenelo. Kodwa ngaphambi kokuba usebenzise ezi valve, kusekho ezinye izinto ekufuneka uzikhumbule.

1. Nangona ivuliwe ngokupheleleyo, indawo encinci yediski iya kuthintela ukuhamba kwezinto. Oku kunokuchaphazela ukunyakaza kwendawo yediski kunye nokutshintshwa koxinzelelo kumbhobho.

2. Umsebenzi wokutywina awulunganga njengezinye iivalvu.

3. I-Trottling isebenza kuphela kwinkonzo yoxinzelelo oluphantsi olwahlukileyo.

4. I-valve ye-butterfly ihlala inomngcipheko wokuthintela ukuhamba okanye i-cavitation.

Ubume bevalve yebhabhathane

Iivalve zebhabhathane zineempawu ezininzi eziphambili. Ezi ziquka umzimba, idiski, isiqu, kunye nesihlalo. Bakwanayo ne-activator, njenge-lever. Umsebenzisi unokujikelezisa i-actuator yevalve ukutshintsha indawo yediski.

Umzimba wevalvu ufakwe phakathi kweeflange ezimbini zepayipi. Eyona nto ixhaphakileyo kuzo zonke iintlobo zoyilo zomzimba ziilugs kunye neediski.

Umgaqo osebenzayo wediski yevalve ufana nesango kwivalve yesango, iplagi kwivalve yeplagi, ibhola kwivalve yesango.ivalve yebhola, njl. Xa ijikeleziswa nge-90 ° ukuhamba ngokuhambelana nolwelo, i-disc ikwindawo evulekileyo. Kule ndawo, i-disc iya kuvumela yonke i-fluid ukuba idlule. Xa i-disc ijikeleza kwakhona, i-disc ingena kwindawo evaliweyo kwaye inqande ukuhamba kwamanzi. Ngokuxhomekeke kwi-disc orientation kunye noyilo, umenzi unokusebenzisa i-torque yokusebenza, itywina kunye / okanye ukuhamba.

Isiqu sevalve yishafti. Inokuba sisiqwenga esinye okanye ezibini. Ukuba yeyokugqibela, ibizwa ngokuba yi-slint stem.

Isihlalo siqhagamshelwe kumzimba wesithuthi ngokucinezela, ukubopha okanye ukutshixa iindlela. Umenzi udla ngokwenza isihlalo sevalve ngepolymer okanye elastomer. Injongo yesitulo sevalve kukubonelela ngomsebenzi wokuvala ivalve. Yiyo loo nto amandla ajikelezayo afunekayo ekuvaleni ivalve yebhabhathane ibizwa ngokuba “yisihlalo setorque”, ngelixa amandla ajikelezayo afunekayo ukuze ivalve yebhabhathane ijikelezise into evalayo ibizwa ngokuba “yi-torque yesitulo.

I-actuator ingaba ngumatshini okanye ngokuzenzekelayo, kwaye ukuhamba ngombhobho kunokulungiswa ngokuhambisa i-disc valve. Xa ivaliwe, idiski yevalve ivala umngxuma wevalve, kwaye ulwelo luhlala lunxibelelana nediski yevalve. Oku kuya kubangela ukuhla koxinzelelo. Ukutshintsha indawo yediski inike ithuba lokuqukuqela kwamanzi, jika isikhondo sibe yikota.
