Umkhiqizi wevalvu yebhola ene-fluorine

I-valve yebhola ehlanganiswe ngensimbi ecijile i-fluorine iqukethe izingxenye eziningana ezibalulekile:

1.1 Umzimba Wevalvu (Insimbi Ehlanganisiwe)

Umzimba wangaphandle uvame ukwenziwa ngama-grade ensimbi ehlanganisiwe njenge-WCB noma i-WC6. Insimbi ehlanganisiwe inikeza:

Amandla aphezulu okusebenza ngomshini

Ikhono elihle kakhulu lokuthwala ingcindezi

Ukumelana nomthelela kanye nokucindezeleka komshini

Ukufaneleka kwezinhlelo ezicindezela kakhulu

Ukwakhiwa kwe-cast kuqinisekisa ubuqotho besakhiwo ngenkathi kusekela ulwelwesi lwangaphakathi lwe-fluorine.

1.2 Ulwelwesi lwe-Fluorine (PTFE, PFA, FEP)

Izindawo zangaphakathi ezithintana noketshezi zimbozwe ngama-polymer asekelwe ku-fluorine. Izinto ezivamile zokubopha ulwelwesi zifaka:

I-PTFE (i-Polytetrafluoroethylene)

I-PFA (i-Perfluoroalkoxy)

I-FEP (i-Fluorinated Ethylene Propylene)

Lezi zinto zihlinzeka:

Ukumelana okungavamile kwamakhemikhali

Isilinganiso sokungqubuzana okuphansi

Izakhiwo ezinganamatheli

Ukumelana nokushisa

Akukho ukugqwala okuvela kuma-asidi amaningi nama-alkali

Ulwelwesi luhlukanisa uketshezi lwenqubo emzimbeni wensimbi, luvimbele ukugqwala.

1.3 Ukuhlanganiswa Kwebhola Nesiqu

Ibhola livame ukwenziwa ngensimbi engagqwali noma insimbi yekhabhoni futhi lifakwe ngokuphelele i-PTFE noma i-fluoropolymer efanayo. Ibhola eliyindilinga elinomshini oqondile liqinisekisa:

Ukuvala okuqinile

Ukusebenza okubushelelezi

Izidingo ezincane ze-torque

Isiqu singafakwa uthango noma sivikelwe ukuze kugwenywe ukuhlaselwa ngamakhemikhali.

1.4 Izihlalo kanye Nezinto Zokuvala

Izihlalo zivame ukwenziwa nge-PTFE noma ama-fluoropolymer aqinisiwe. Zihlinzeka:

Ukuvala okuqinile njengebhamuza

I-torque yokusebenza ephansi

Ukumelana nokuguqulwa

Izinhlelo zokuvala ezisezingeni eliphezulu zivimbela ukuvuza futhi ziqinisekisa ukuhambisana nezindinganiso zokuphepha eziqinile zezimboni.

3.1 Ukumelana Okuphezulu Kokugqwala

Ama-valve ebhola ane-fluorine alungele ukuphathwa:

Ama-asidi aqinile (i-asidi ye-sulfuric, i-asidi ye-hydrochloric)

Ama-alkali aqinile

Izithako ezifakwe i-chlorine

Ama-ejenti okuxoxisa

Amakhemikhali anobuthi

Ulwelwesi lwe-PTFE luvimbela ukuvezwa kwensimbi, luqede ukwehluleka okuhlobene nokugqwala.

3.2 Ukusebenza Okuhle Kakhulu Kokuvala

Lawa ma-valve awavuzi nhlobo uma efakwe kahle. Izihlalo ze-PTFE ezithambile ziqinisekisa ukuvalwa okuqinile ngisho noma kucindezelwe kancane.

3.3 Ububanzi Bezinga Lokushisa Elibanzi

Ngokuvamile, ama-valve ebhola ane-fluorine asebenza ngaphakathi:

–20°C kuya ku-+180°C (kuye ngokuthi indwangu injani)

Amavalvu afakwe i-PFA angamelana namazinga okushisa aphezulu uma kuqhathaniswa ne-PTFE ejwayelekile.

3.4 I-Torque Ephansi Yokusebenza

Ubuso obubushelelezi be-fluoropolymer kunciphisa kakhulu ukungqubuzana, okuvumela ukusebenza okulula ngesandla noma okuzenzakalelayo.

3.5 Impilo Ende Yenkonzo

Inhlanganisela yokumelana nokugqwala kanye nomklamo oqinile wesakhiwo yandisa isikhathi sokusebenza, okunciphisa izindleko zokulungisa.

Amavalvu ebhola ane-fluorine ensimbi asetshenziswa kabanzi kuzo zonke izimboni lapho ukumelana namakhemikhali kubaluleke kakhulu.

4.1 Imboni Yamakhemikhali

Isetshenziselwa ukulawula amakhemikhali anolaka ku:

Imigqa yokudlulisa i-asidi

Izinhlelo zokucubungula i-alkali

Ukuphathwa kwe-chlorine

Ukuthuthwa kwe-solvent

4.2 Imboni Ye-Petrochemical

Ifanelekela izinto ezisetshenziswayo ezibhubhisayo ze-petrochemical kanye nezinto eziyingozi.

4.3 Imboni Yezemithi

Amavalvu afakwe i-PTFE aqinisekisa ukucutshungulwa okungenakho ukungcola kanye nezindinganiso zobumsulwa obuphezulu.

4.4 Izitshalo Zikagesi

Isetshenziswa ezinhlelweni zokususa i-flue gas kanye nemigqa yokulinganisa amakhemikhali.

4.5 Izitshalo Zokuhlanza Amanzi

Isebenza kahle ekuphatheni uketshezi lokwelapha olune-asidi kanye nolwekhemikhali.

Kuye ngezidingo zesistimu, kunezinto eziningana ezilungiselelwe:

5.1 Uhlobo Lwebhola Elintantayo

Ibhola lisekelwa yizihlalo

Ifanele ukucindezela okuphakathi nokuphansi

Okuvamile emipayipini yamakhemikhali

5.2 Uhlobo Olufakwe I-Trunnion

Ibhola lisekelwe yizinsika

Ilungele ukusetshenziswa komfutho ophezulu

I-torque yokusebenza encishisiwe

5.3 Ivalvu Esetshenziswa Ngesandla

Iqhutshwa nge-lever noma i-handwheel.

5.4 I-Activated Valve

Ifakwe ama-actuator omoya, ama-actuator kagesi, ama-actuator e-hydraulic, njll. Ukuzenzakalela kuthuthukisa ukuphepha ezindaweni eziyingozi.

Isici I-Fluorine Lined Ball Valve I-Valve Yensimbi Ejwayelekile

Ukumelana Nokugqwala Kuhle kakhulu Kunqunyelwe

Ukuhambisana Kwamakhemikhali Kuphezulu kakhulu Okumaphakathi

Imvamisa Yokulungisa Phansi Phezulu

Impilo Yesevisi Kude Okufushane kumidiya ebolile

Ukuvikelwa Kokuvuza Kuhle kakhulu Okumaphakathi

Ulwelwesi lwe-fluorine lunikeza isithiyo esivikelayo esithuthukisa kakhulu ukusebenza kwezicelo ezigqwalisayo.

Ukufakwa kahle kuqinisekisa ukusebenza kahle:

- Qinisekisa ukuthi ipayipi lihambisana kahle ngaphambi kokufakwa.

- Gwema ukuqinisa kakhulu amabhawodi e-flange.

- Sebenzisa ama-gasket afanele ahambisana noketshezi lwenqubo.

- Ungashiseli eduze kwevalvu efakwe uthango ngaphandle kokuvikelwa okufanele.

- Landela imininingwane ye-torque yomkhiqizi.

Ukufakwa okungalungile kungalimaza ulwelwesi futhi kuphazamise ukusebenza kahle kwalo.

Nakuba ama-valve ebhola ane-fluorine edinga ukulungiswa okuncane, ukuhlolwa njalo kuyanconywa:

- Hlola ukuvuza kwangaphandle.

- Hlola umsebenzi we-actuator.

- Qinisekisa ukuthi i-valve ijikeleza kahle.

- Qinisekisa ukusebenza kokuvala.

Gwema izinto ezilimazayo, njengoba ulwelwesi lwe-fluoropolymer lungalinyazwa yizinhlayiya eziqinile.

Lawa ma-valve avame ukukhiqizwa ngokuhambisana nezindinganiso zomhlaba wonke njengezindinganiso ze-API, amazinga e-ANSI, amazinga e-ISO, amazinga e-DIN, njll. Izilinganiso zokucindezela zivame ukufaka i-Class 150, i-Class 300. Ukuxhumeka kwe-Flange kungahambisana ne-ANSI B16.5 noma imininingwane ye-DIN.

Uma ukhetha i-valve yebhola ene-fluorine yensimbi ephonswe ngensimbi, cabanga ngalokhu:

- Uhlobo lwemidiya yamakhemikhali

- Izinga lokushisa lokusebenza

- Ingcindezi yokusebenza

- Izidingo zesilinganiso sokugeleza

- Usayizi we-valve

- Uhlobo lokuxhumana lokugcina

- Izidingo zokwenza izinto ngokuzenzakalela

- Ukukhetha okufanele kuqinisekisa ukuphepha nokusebenza kahle.

Nakuba imelana kakhulu nokugqwala, ama-valve ebhola ane-fluorine anemikhawulo ethile:

- Akufanele umusi oshisa kakhulu ngaphezu kwemingcele ye-lining

- Akufanelekile ukusetshenziswa kwe-slurry ekhuhlayo

- Umonakalo wendwangu ungadinga ukushintshwa kwevalvu ephelele

- Ukuqina kwesakhiwo okulinganiselwe uma kuqhathaniswa nezihlalo zensimbi eqinile lapho zicindezeleke kakhulu

- Ukuqonda le mikhawulo kusiza ukuvimbela izinkinga zokusebenza.
