Isingeniso se-Butterfly Valve

Isingeniso:

I-valve yevemvanekuvela emndenini wama-valve abizwaama-valves we-quarter. Ukusebenza, i-valve ivuleke ngokuphelele noma ivaliwe lapho i-disc ijikeleza ikota ijika. I- "Butterfly" iyi-disc yensimbi efakwe endongeni. Lapho i-valve ivaliwe, i-disc iphendukile ukuze ivimbe ngokuphelele indlela. Lapho i-valve ivulekile ngokuphelele, i-disc ijikeleze ikota iphenduka ukuze ivumele indawo ecishe ibe ngaphansi koketshezi. I-valve ingaphinde ivulwe kakhulu ekuhambeni kwe-throttle.

Kunezinhlobo ezahlukene zama-butterfly valves, ngalinye livumelaniswe nezingcindezi ezahlukahlukene nokusetshenziswa okuhlukile. I-valve ye-zero-offsetty butterfly, esebenzisa ukuguquguquka kwenjoloba, inesilinganiso esiphansi kakhulu sokucindezela. I-valve ye-butterfy esebenza kahle ephezulu, esetshenziswe ezinhlelweni eziphakeme zengcindezi, i-offset kancane kusuka kulayini wesikhungo wesihlalo se-disc kanye nophawu lomzimba (i-offset eyodwa), kanye nomugqa wesikhungo sababili). Lokhu kudala isenzo se-cam ngesikhathi sokusebenza ukuphakamisa isihlalo esiphuma ku-seal kuphumela ekungqubuzaneni okuncane kunalokho okwenziwe ku-zero offset design futhi kwehlise ukuthambekela kwayo. I-valve elungele kahle izinhlelo zengcindezi ephezulu iyi-valve ye-vertfy offt. Kule value i-disc teation chark aksisi i-offset, esebenza cishe ngokususa ukuxhumana ngokuslayida phakathi kwe-disc nesihlalo. Endabeni ye-three offset valves isihlalo senziwa ngensimbi ukuze ifakwe emnyameni njengokuthola i-bubble ivaliwe lapho uxhumana ne-disc.

Izinhlobo

1. Ama-valve aqinile wevemvane- Lolu hlobo lwe-valve lunesihlalo senjoloba esiqinile nge-disc yensimbi.
2. Ama-valves we-Butter-eccentric(Ama-valves we-butterfly aphezulu aphezulu noma ama-valves aphindwe kabili ama-butterfly) - Uhlobo oluhlukile lwezinto zokwakha lusetshenziselwa isihlalo ne-disc.
3. Ama-valves we-vetterfly e-eccentric(Ama-valves we-butterfly we-triple

Ama-valves we-butterfly onqenqema

Le khasiI-waferk isitayela uvemvane valveyakhelwe ukugcina uphawu ngokumelene nengcindezelo eqondile yengcindezelo ukuvikela noma yikuphi ukubuyela emuva ezinhlelweni ezenzelwe ukugeleza kwe-UNDIRREctival. Kufeza lokhu ngophawu olufanelekile; Yebo, i-gasket, i-O-ring, ukunemba komshini, kanye nobuso be-valve flat on the upstream kanye nezinhlangothi ezansi kwe-valve.

I-valve ye-butterfly ye-lug-style

Ama-valves wesitayela se-lugsebefakiwe ezinhlangothini zombili zomzimba we-valve. Lokhu kubavumela ukuthi bafakwe ohlelweni besebenzisa amasethi amabili ama-bolts futhi akukho amantongomane. I-valve ifakwe phakathi kwama-flanges amabili usebenzisa isethi ehlukile yama-bolts nge-flange ngayinye. Lokhu kusethwa kuvumela zombili izinhlangothi zohlelo lwamapayipi ukuthi zinqanyulwe ngaphandle kokuphazamisa olunye uhlangothi.

I-valve yama-butter-stylety-stylely esetshenziselwa insiza yokuphela efile ngokuvamile inesilinganiso sokuncipha kwengcindezi. Isibonelo, kufakwe i-butter-tylely valvely valve phakathi kwama-flanges amabili ine-1,000 KPA (150 PSI) ukulinganisa kwengcindezelo. I-valve efanayo ibekwe nge-flange eyodwa, in service yokuphela efile, inesilinganiso esingu-520 KPA (75 PSI). Ama-valves agxunyekiwe amelana kakhulu namakhemikhali nama-sols futhi angaphatha amazinga okushisa aze afike ku-200 ° C, okwenza kube yisixazululo esiguquguqukayo.

Sebenzisa embonini

Embonini yamakhemikhali, amakhemikhali, kanye nokudla, i-valve yakudala isetshenziselwa ukuphazamisa ukuhamba komkhiqizo (okuqinile, uketshezi, igesi) ngaphakathi kwenqubo. Ama-valve asetshenziswe kulezi zimboni ngokuvamile akhiqizwa ngokuhambisana nemihlahlandlela ye-CGMP (umkhuba wamanje wokukhiqiza okuhle). Ama-butterfly ama-valves abeka ngokuvamile ama-valves webhola afakwe esikhundleni sezimboni eziningi, ikakhulukazi u-petroleum, ngenxa yezindleko eziphansi kanye nokufakwa kalula, kepha amapayipi aqukethe ama-butterfly angeke 'anezingulube' zokuhlanza.
