Uyini umehluko phakathi kwama-trunnion nama-floating ball valve?

Amavalvu ebhola le-trunnion kanye namavalvu ebhola antantayo womabili ayizinhlobo zamavalvu ebhola asetshenziselwa ukulawula ukugeleza koketshezi ngepayipi. Umehluko omkhulu phakathi kwalokhu kokubili yindlela ibhola elisekelwa ngayo ngaphakathi komzimba wevalvu.

Ku-valve yebhola ye-trunnion, ibhola lisekelwa yi-trunnion ezimbili, okuyiziqongo ezincane eziyisilinda ezisuka phezulu nangaphansi kwebhola. Ama-trunnion atholakala kuma-bearings emzimbeni we-valve, okuvumela ibhola ukuthi lijikeleze kahle lapho i-valve ivulwa noma ivaliwe.

Ku-valve yebhola entantayo, ibhola alisekelwa yizikhonkwane. Kunalokho, livunyelwe "ukuntanta" ngaphakathi komzimba we-valve, liqondiswa yindandatho yokuvala. Lapho i-valve ivuliwe noma ivaliwe, ibhola liya phezulu noma phansi ngaphakathi komzimba we-valve, liqondiswa yindandatho yokuvala.

Womabili ama-valve ebhola le-trunnion nama-valve ebhola antantayo anezinzuzo zawo kanye nokungalungi kwawo. Ama-valve ebhola le-trunnion ngokuvamile aqinile kakhulu futhi angabhekana nokucindezela okuphezulu kanye nokushisa, kodwa futhi abiza kakhulu ukuwakhiqiza. Ama-valve ebhola antantayo ayonga kakhulu futhi kulula ukuwafaka, kodwa awafanele ukusetshenziswa kokucindezela okuphezulu noma ukushisa.

Yiziphi izinhlobo ezahlukene zama-valve antantayo?

Kunezinhlobo eziningana zama-valve okuntanta, okuhlanganisa:

1.Ivalvu yokuntanta yohlobo lwe-Plunger: Lolu hlobo lwevalvu yokuntanta lusebenzisa i-plunger enamathiselwe ku-float. Lapho izinga loketshezi likhuphuka, i-float iyaphakama nayo, okubangela ukuthi i-plunger icindezele esihlalweni se-valve, ivale ivalvu. Lapho izinga loketshezi liwa, i-float iyawa nayo, okuvumela ivalvu ukuthi ivuleke.

2.I-valve ye-Ballcock: Lolu hlobo lwe-valve entantayo luvame ukusetshenziswa ezindlini zangasese ukulawula ukugeleza kwamanzi ethangini. Luqukethe i-float enamathiselwe esiqwini se-valve, elawula ukugeleza kwamanzi.

3.Ivalvu yokuntanta yohlobo lwe-diaphragm: Lolu hlobo lwevalvu yokuntanta lusebenzisa i-diaphragm eguquguqukayo enamathiselwe ku-float. Lapho izinga loketshezi likhuphuka, i-float iyakhuphuka nayo, okwenza i-diaphragm icindezele esihlalweni se-valve, ivale i-valve.

4.Ivalvu yokuntanta efana nohlobo lwe-paddle: Lolu hlobo lwevalvu yokuntanta lusebenzisa i-paddle exhunywe ku-float. Lapho izinga loketshezi likhuphuka, i-float iyakhuphuka nayo, okwenza i-paddle icindezele isihlalo se-valve, ivale i-valve.

5.I-valve yokuntanta ye-electromagnetic: Lolu hlobo lwe-valve yokuntanta lusebenzisa i-electromagnet ukulawula ukugeleza koketshezi. Lapho izinga loketshezi likhuphuka, i-float ivuselela i-electromagnet, yona evuselela i-valve ukuvala ukugeleza koketshezi.

Iyini inhloso yevalvu yokuntanta?

Inhloso eyinhloko yevalvu yokuntanta ukulawula ngokuzenzakalelayo ukugeleza koketshezi olungena noma oluphuma esitsheni noma ethangini. Amavalvu okuntanta avame ukusetshenziswa ezinhlotsheni ezahlukene, okuhlanganisa:

1.Amathangi endlu yangasese: Amavalvu e-Ballcock asetshenziselwa ukulawula ukugeleza kwamanzi ethangini.

2.Amathangi amanzi: Amavalvu antantayo asetshenziselwa ukugcina izinga lamanzi lihlala linjalo emathangini, ngokuvumela amanzi ukuthi angene lapho izinga liphansi nokuvala ukugeleza lapho izinga liphezulu.

3.Izinhlelo zokunisela: Amavalvu okuntanta asetshenziswa ukulawula ukugeleza kwamanzi emasimini noma engadini.

4.Amathangi okugcina amakhemikhali: Amavalvu antantayo asetshenziselwa ukugcina izinga elithile loketshezi emathangini okugcina amakhemikhali, ukuqinisekisa ukuthi amakhemikhali awaxutshwanga kakhulu noma kancane.

5.Imibhoshongo Yokupholisa: Amavalvu okuntanta asetshenziselwa ukulawula ukugeleza kwamanzi emibhoshongweni yokupholisa, ukuze kugcinwe izinga lamanzi lihlala linjalo.

Sekukonke, ama-float valve asetshenziswa ukulawula ngokuzenzakalelayo ukugeleza koketshezi ezinhlotsheni ezahlukene zokusebenza lapho kudingeka khona izinga loketshezi elingaguquki.
