Yintoni umahluko phakathi kwe-trunnion kunye neevalvu zebhola ezidadayo?

Iivalvu zebhola ye-trunnion kunye neevalvu zebhola ezidadayo zombini ziintlobo zeevalvu zebhola ezisetyenziselwa ukulawula ukuhamba kolwelo ngombhobho.Umahluko omkhulu phakathi kwezi zimbini yindlela exhaswa ngayo ibhola ngaphakathi kumzimba wevalve.

Kwivalve yebhola yetrunnion, ibhola ixhaswa ziitrunnions ezimbini, eziziingqikelelo zecylindrical ezincinci ezisuka phezulu nasezantsi kwebhola.I-trunnions ifumaneka kwiibheringi kumzimba wevalve, evumela ibhola ukuba ijikeleze kakuhle xa ivalve ivuliwe okanye ivaliwe.

Kwivalve yebhola edadayo, ibhola ayixhaswa ziitrunnions.Endaweni yoko, ivumelekile ukuba "idada" ngaphakathi komzimba wevalve, ikhokelwa ngumsesane wokutywina.Xa ivalve ivuliwe okanye ivaliwe, ibhola ishukuma inyuka okanye ihla ngaphakathi kumzimba wevalvu, ikhokelwe ngumsesane wokutywina.

Zombini iivalvu zebhola ze-trunnion kunye neevalvu zebhola ezidadayo zineenzuzo kunye nezingeloncedo zazo.Iivalvu zebhola ze-Trunnion zomelele ngakumbi kwaye ziyakwazi ukumelana noxinzelelo oluphezulu kunye nobushushu, kodwa zikwabiza kakhulu ukwenziwa.Iivalve zebhola ezidadayo zinoqoqosho ngakumbi kwaye kulula ukuzifaka, kodwa azifanelekanga kuxinzelelo oluphezulu okanye izicelo zobushushu.

Zeziphi iintlobo ezahlukeneyo zeevalvu ezidadayo?

Kukho iindidi ezininzi zeevalvu ezidadayo, kuquka:

1.Ivalve yohlobo lwePlunger: Olu didi lwevalve edadayo lusebenzisa iplunger encanyatheliswe kwindawo edadayo.Xa umgangatho wolwelo uphakama, i-float iphakama kunye nayo, ibangela ukuba iplunger ityhale kwisitulo sevalve, ivale ivalve.Xa inqanaba lolwelo liwa, i-float iwela nayo, ivumela ivalve ukuba ivuleke.

2.Ivalve ye-Ballcock: Olu hlobo lwevalve edadayo luqhele ukusetyenziswa kwizindlu zangasese ukulawula ukuhamba kwamanzi etankini.Iquka intonga edadayo encanyatheliswe kwisiqu sevalvu, elawula ukuhamba kwamanzi.

3.Ivalve yohlobo lwe-diaphragm: Olu hlobo lwevalve yevalve lusebenzisa idiaphragm ethambileyo encanyatheliswe kwindawo edadayo.Xa umgangatho wolwelo uphakama, i-float iphakama kunye nayo, ibangela ukuba i-diaphragm icinezele kwisitulo sevalve, ivale ivalve.

4.Ivalve yohlobo lokudada: Olu hlobo lwevalve yevalufa lusebenzisa iphini lokubheqa elincanyatheliswe kwindawo edadayo.Xa umgangatho wolwelo uphakama, i-float iphakama kunye nayo, ibangela ukuba i-paddle ityhale kwisitulo sevalve, ivale ivalve.

5.Ivalve yokudada ye-Electromagnetic: Olu didi lwevalve edadayo lusebenzisa i-electromagnetic ukulawula ukuhamba kolwelo.Xa umgangatho wolwelo uphakama, i-float ivula i-electromagnetic, ethi yona ivule ivalve ukuvala ukuhamba kolwelo.

Yintoni injongo yevalvu edadayo?

Eyona njongo yevalvu edadayo kukulawula ngokuzenzekelayo ukungena okanye ukuphuma kolwelo kwisikhongozelo okanye itanki.Iivalvu ezidadayo ziqhele ukusetyenziswa kwiintlobo ngeentlobo zezicelo, kubandakanywa:

1.Iitanki zezindlu zangasese: Izivalo zeBallcock zisetyenziselwa ukulawula ukuhamba kwamanzi etankini.

2.Iitanki zamanzi: Iivalvu ezidadayo zisetyenziselwa ukugcina inqanaba lamanzi elingaguqukiyo kumatanki, ngokuvumela amanzi ukuba angene xa umgangatho uphantsi kwaye uvale ukuhamba xa umgangatho uphezulu.

3.Iinkqubo zokunkcenkceshela: Izivalo ezidadayo zisetyenziselwa ukulawula ukuhamba kwamanzi emasimini okanye ezitiyeni.

4.Iitanki zokugcina imichiza: Iivalvu ezidadayo zisetyenziselwa ukugcina umgangatho othile wolwelo kwiitanki zokugcina imichiza, ukuqinisekisa ukuba iikhemikhali azixutywanga ngaphezulu okanye ngaphantsi.

5.Iinqaba zokupholisa: Iivalvu ezidadayo zisetyenziselwa ukulawula ukuhamba kwamanzi kwiinqaba zokupholisa, ukugcina umgangatho wamanzi ongatshintshiyo.

Ngokubanzi, iivalvu ze-float zisetyenziselwa ukulawula ngokuzenzekelayo ukuhamba kolwelo kwiinkqubo ezahlukeneyo apho umgangatho wolwelo oqhubekayo kufuneka ugcinwe.
