Ulwakhiwo lwevalvu yebhola lwahlulwe ngohlobo oludadayo nohlobo olusisigxina

Ivalvu yebhola esisigxina

Kukho umngxuma phantsi kwevalvu yokulungisa ivalvu yebhola. Embindini kukho ivalvu yebhola. Kukho isiqu sevalvu kumacala aphezulu nasezantsi okulungisa ibhola embindini. Ukusuka ngaphandle, ngokubanzi, ivalvu yebhola enenqaku lokuxhasa idiski phantsi kwevalvu yebhola yivalvu yebhola esisigxina.

Ivalvu yebhola edadayo

Ibhola iyadada embindini, kwaye akukho ndawo yokuxhasa ngezantsi kukho ivalvu yebhola edadayo

Ububanzi obukhulu bevalvu yebhola edadayo ngokubanzi yi-DN250

Ububanzi obukhulu bevalvu yebhola esisigxina bunokuba yi-DN1200

Umahluko omkhulu phakathi kweevalvu zebhola ezizinzileyo nezidadayo usekwe ekufakweni kwebhola ephakathi. Ukufakelwa kwonakalisa isitywino ngokwahlukileyo. Uhlobo oluzinzileyo luphucula ubomi benkonzo yevalvu yebhola. Ivalvu yebhola ezinzileyo inobomi obude benkonzo kunevalvu yebhola edadayo. Ibhola yohlobo lwevalvu yebhola iyadada kwaye ijikeleze kwindawo engaphakathi, nto leyo eya kubangela ukuba isitywino sidada kwaye sitshone. Xa ivalvu yebhola ijikeleza, iindawo zoxinzelelo zahlukile. Ukuba akukho ndawo ixhasayo, iya konakalisa isitywino kumacala omabini. Logama nje ivalvu yebhola isetyenziswa, iya kubangela amazinga ahlukeneyo okulahleka koxinzelelo. Xa ibhola inendawo exhasayo, ayiyi kubangela ukulahleka koxinzelelo okanye umphezulu wokulahleka koxinzelelo uya kuba mncinci kakhulu, ngoko ke ubomi bevalvu yebhola ezinzileyo bude kunobohlobo oludadayo. , Kungcono ukusebenzisa ivalvu yebhola ezinzileyo ngamanye amaxesha ene-frequency ephezulu yokutshintsha.

Ivalvu yebholaukutywina

Iivalvu zebhola ziquka iivalvu zebhola ezimile okwe-V, iivalvu zesiqingatha sebhola ezingaqhelekanga,Iivalvu zebhola zePVC, njl. njl.

Ezi ziivalvu ezahlukeneyo ezichazwe ngokweemeko ezahlukeneyo

Ivalvu yebhola yohlobo lwe-V

Indlela yokuhamba kwevalvu yebhola enomfanekiso we-V yivalvu yebhola ene-port ye-V esikiweyo, eyivalvu yebhola esisigxina

Ububanzi bokusetyenziswa: I-V port icutshungulwe ngokukodwa. Yinto emile okwe-V. Njengemela, umsebenzi wayo kukusika iifayibha ezithile. Kwezinye iinxalenye eziqinileyo, iya kutyunyuzwa ngqo. Indlela yokucubungula ibhola nayo yahlukile. Ingakumbi ezinye iifektri zine-sewage okanye ezinye iigranular media eziqinileyo, njengolu hlobo lwe-V-shaped ball valve lusetyenziswa rhoqo.

Ivalvu yesiqingatha sebhola edibeneyo

Ivalvu ye-hemispherical engaqhelekanga ifana nevalvu yebhola enomfanekiso we-V. Ingaphakathi levalvu liyisiqingatha kuphela, kwaye ikwayivalvu yebhola esisigxina. Isetyenziswa kakhulu kwiisuntswana eziqinileyo. Zonke iivalvu zebhola yesuntswana eziqinileyo zisebenzisa iivalvu ze-hemispherical engaqhelekanga. Izityalo ezininzi zesamente nazo ziyayisebenzisa le.

Zombini ivalvu yebhola enomfanekiso we-V kunye nevalvu ye-semi-ball engaqhelekanga zijikeleza kwicala elinye kuphela, kungekhona kwicala elinye, kuba ibhola yayo ivaliwe kwicala elinye, kwaye itywina ayizukuqina xa ibethelwa ngecala elingasemva, kodwa ihamba kwicala elinye kuphela. Ukutywina kuya kuba ngqongqo xa kufakwa uxinzelelo.

Ivalvu yebhola yePVC

Izitywino zeIivalvu zePVCzii-EPDM kuphela (i-ethylene propylene diene monomer), i-FPM (irabha yefluorine)

Ivalvu yebhola yotywino oluqinileyo

Isitywina esiqinileyo sinophawu olukhethekileyo

Kukho intwasahlobo emva kwesihlalo sevalvu esitywiniweyo, kuba ukuba isihlalo sevalvu esitywiniweyo kunye nebhola zidibene ngokuthe ngqo, aziyi kujika. Xa intwasahlobo iqhagamshelwe emva kwesihlalo sevalvu, ibhola iya kuba nokuguquguquka ngexesha lokujikeleza, kuba itywina eliqinileyo Ingxaki ekufuneka isonjululwe kukuba ibhola inokusebenza ngokuqhelekileyo, kodwa ibhola iya kukhuhla rhoqo yi-medium. Ukuba ezinye iisuntswana zinamathele kwitywina lesihlalo sevalvu, ayinakusetyenziswa. Ke ngoko, inokolulwa kancinci kwaye ixhomekeke kubunzima bebhola ukuze yolulwe. Ukuba yitywina ethambileyo, ukuba iisuntswana zinamathele kwitywina, ivalvu iya konakaliswa ngokuthe ngqo xa ivaliwe. Itywina eliqinileyo lifana nevalvu yebhola enomfanekiso we-V ngaphambi kokuba iphume kumzi-mveliso ene-S60 engaphezulu. Itywina kunye nebhola ziqinile, ngoko ke zihlala zizinto ezinzima. Ayizukuphuka ukuba uyikrwela kancinci

Itywina le-PPL

Itywina likwanayo ne-PPL material, igama layo yi-PTFE eyongeziweyo, izinto eziluhlaza yi-polytetrafluoroethylene, kodwa i-graphite yongezwa ukuze iguqulwe ibe kukumelana nobushushu obuphezulu, ubushushu obuphezulu bungafikelela kwi-300 ° (hayi ukuxhathisa ixesha elide kwi-300 ° Ubushushu obuphezulu), ubushushu obuqhelekileyo buyi-250 °. Ukuba ufuna ixesha elide le-300 °, kuya kufuneka ukhethe ivalvu yebhola yetywina eqinileyo. Ukumelana nobushushu obuphezulu obuqhelekileyo kwetywina eqinileyo kungafikelela kwi-450 °, kwaye ubushushu obuphezulu bufikelela kwi-500 °.
