Yintoni umahluko phakathi kwe-trunnion kunye ne-floating ball valves?

Iivalvu zebhola zeTrunnion kunye neevalvu zebhola ezidadayo zombini ziintlobo zeevalvu zebhola ezisetyenziselwa ukulawula ukuhamba kolwelo ngombhobho. Umahluko ophambili phakathi kwezi zimbini yindlela ibhola exhaswa ngayo ngaphakathi komzimba wevalvu.

Kwivalvu yebhola yetrunnion, ibhola ixhaswa ziitrunnion ezimbini, eziziiprojektha ezincinci ze-cylindrical ezisuka phezulu nasezantsi kwebhola. Iitrunnion zibekwe kwiibheringi emzimbeni wevalvu, ezivumela ibhola ukuba ijikeleze kakuhle xa ivalvu ivuliwe okanye ivaliwe.

Kwivalvu yebhola edadayo, ibhola ayixhaswa zii-trunnion. Endaweni yoko, ivumelekile ukuba "idadayo" ngaphakathi komzimba wevalvu, ikhokelwa yiringi yokutywina. Xa ivalvu ivuliwe okanye ivaliwe, ibhola iya phezulu okanye yehla ngaphakathi komzimba wevalvu, ikhokelwa yiringi yokutywina.

Zombini iivalvu zebhola ye-trunnion kunye neevalvu zebhola ezidadayo zinezibonelelo kunye neengxaki zazo. Iivalvu zebhola ye-trunnion zihlala ziqinile kwaye zinokumelana noxinzelelo oluphezulu kunye nobushushu, kodwa zibiza kakhulu ukuzenza. Iivalvu zebhola ezidadayo zingabizi kakhulu kwaye kulula ukuzifaka, kodwa azifanelekanga ukusetyenziswa koxinzelelo oluphezulu okanye ubushushu.

Ziziphi iintlobo ezahlukeneyo zeevalvu ezidadayo?

Kukho iintlobo ezahlukeneyo zeevalvu ezidadayo, eziquka:

1.Ivalvu yokudada yohlobo lwePlunger: Olu hlobo lwevalvu yokudada lusebenzisa iplunger enamathele kwifloat. Xa inqanaba lolwelo linyuka, ifloat inyuka nayo, nto leyo ebangela ukuba iplunger ityhale isihlalo sevalvu, ivale ivalvu. Xa inqanaba lolwelo lihla, ifloat iwa nayo, nto leyo evumela ivalvu ukuba ivuleke.

2.Ivalvu yebhola: Olu hlobo lwevalvu edadayo lusetyenziswa kakhulu kwizindlu zangasese ukulawula ukuhamba kwamanzi ukuya etankini. Luqulathe i-float enamathele kwisiqu sevalvu, elawula ukuhamba kwamanzi.

3.Ivalvu yokudada efana ne-diaphragm: Olu hlobo lwevalvu yokudada lusebenzisa i-diaphragm eguquguqukayo enamathele kwi-float. Xa inqanaba lolwelo linyuka, i-float iyanyuka kunye nayo, nto leyo ebangela ukuba i-diaphragm icinezele isihlalo se-valve, ivale i-valve.

4.Ivalvu yokudada efana nephedi: Olu hlobo lwevalvu yokudada lusebenzisa iphedi enamathele kwiphedi yokudada. Xa inqanaba lolwelo linyuka, iphedi yokudada inyuka nayo, nto leyo ebangela ukuba iphedi ityhale isihlalo sevalvu, ivale ivalvu.

5.Ivalvu yokudada ye-electromagnetic: Olu hlobo lwevalvu yokudada isebenzisa i-electromagnet ukulawula ukuhamba kolwelo. Xa inqanaba lolwelo linyuka, i-float ivuselela i-electromagnet, ethi yona isebenze ivalvu yokuvala ukuhamba kolwelo.

Yintoni injongo yevalvu edadayo?

Eyona njongo iphambili yevalvu edadayo kukulawula ngokuzenzekelayo ukuhamba kolwelo olungena okanye oluphuma kwisikhongozeli okanye itanki. Iivalvu ezidadayo zihlala zisetyenziswa kwiindlela ezahlukeneyo zokusebenza, kuquka:

1.Iitanki zendlu yangasese: Iivalvu zeBallcock zisetyenziselwa ukulawula ukuhamba kwamanzi etankini.

2.Iitanki zamanzi: Iivalvu ezidadayo zisetyenziselwa ukugcina inqanaba lamanzi lingaguqukiyo kwiitanki, ngokuvumela amanzi ukuba angene xa inqanaba liphantsi kwaye avale ukuhamba kwamanzi xa inqanaba liphezulu.

3.Iinkqubo zokunkcenkceshela: Iivalvu zokudada zisetyenziselwa ukulawula ukuhamba kwamanzi ukuya emasimini okanye kwiigadi.

4.Iitanki zokugcina iikhemikhali: Iivalvu ezidadayo zisetyenziselwa ukugcina inqanaba elithile lolwelo kwiitanki zokugcina iikhemikhali, ukuqinisekisa ukuba iikhemikhali azixutywanga kakhulu okanye azixutywanga ngokwaneleyo.

5.Iinqaba zokupholisa: Iivalvu ezidadayo zisetyenziselwa ukulawula ukuhamba kwamanzi kwiinqaba zokupholisa, ukugcina inqanaba lamanzi lihlala lihleli.

Ngokubanzi, iivalvu ezidadayo zisetyenziselwa ukulawula ngokuzenzekelayo ukuhamba kolwelo kwiindlela ezahlukeneyo zokusebenza apho kufuneka kugcinwe inqanaba lolwelo elingaguqukiyo.
