Anto ray pandumaan tan kimey na sakey ya eksentriko, doble ya eksentriko tan taloran eksentriko ya butterfly valve

Sakey ya eksentrikon balbula na kulibangbang

Pian nasolbar so problema ed extrusion ed baetan na disc tan say valve seat na concentric butterfly valve, say single eccentric butterfly valve so nagawa. Ibuybuyak tan bawasan so alablabas ya ipaway na tagey tan leksab a sampot na butterfly plate tan say yurongan na balbula. Balet, lapud saksakey ya eksentriko ya istruktura, say panagkiskis ed baetan na disc tan say yurongan na balbula et ag naandi legan na interon proseso na panlukas tan pansara na balbula, tan say laknab na pangiyaplika et mipara ed concentric butterfly valve, kanian ag-itan masyadon nausar.

Doble ya eksentrikon balbula na kulibangbang

Base ed saksakey ya eccentric butterfly valve, saya so say doblin eksentrikon balbula na kulibangbang ya malaknab ya uusaren natan. Say istruktural a kabiangan to et say sentro na shaft na valve stem et onarawi ed sentro na disc tan sentro na laman. Say epekto na doble ya eccentricity et mamapawala na disc ya ontaynan ed valve seat kayari na pangilukas na valve, ya mamaandi ed agnakaukolan ya sobran extrusion tan scratching ed baetan na disc tan say valve seat, mamapaabeba ed opening resistance, mamapaabeba na wear, tan mamaaligwas ed bilay na Seat. Say panag-scrape et nabawasan a maong, tan diad saman met a panaon,say doblin eksentrikon balbula na kulibangbang nayarin mangusar met na metal ya yurongan na balbula, ya mamaaligwas ed pangiyaplika na balbula na kulibangbang ed atagey a petang a lawak. Balet, lapud say prinsipyo na panagselyo to et positional sealing structure, salanti, say sealing surface na disc tan say valve seat et mankakasakey, tan say elastic deformation ya sengegan na disc extrusion na valve seat et mamapawala na sealing effect, kanian walaan na atagey iran kakaukolanen parad posisyon na panagsara (lalo la ed metal ya Valve seat), abeban presyon na kapasidad na sea, ya rason no akin ya tradisyonal ya iisipen na totoo saray balbula na kulibangbang et ag makalaban ed atagey a presyon tan walaan na baleg a panag-agus.

Triple eccentric butterfly valve

Pian nasungdoan so atagey a petang, kaukolan so mangusar na malet a selyo, balet ta baleg so onlelesa; pian anggapoy itagas, kaukolan ya usaren so anlemew ya seal, balet ag-itan makalaban ed atagey ya temperatura. Pian natalonaan so kontradiksyon na doble ya eksentrikon balbula na kulibangbang, say balbula na kulibangbang so nagmaliw ya eksentriko ed komatlon pankanawnawa. Say istruktural a kabiangan to et legan ya say doblin eccentric valve stem et eccentric, say conical axis na disc sealing surface et aka-inclin ed cylinder axis na laman, salanti, kayari na komatlon eccentricity, say sealing section na disc et ag manguuman. Insan sakey itan a peteg a sirkulo, balet ta sakey ya ellipse, tan say kurti na tapew na sealing to et agmet simetriko, say sakey a diking et akakiling ed sentro na linya na laman, tan say sananey a diking et mipara ed sentro na linya na laman. Say katangian na sayan komatlon inka-excentricity et say istruktura na seal et manunan anguman, aliwa lan position seal, no ag ingen torsion seal, salanti, ag-itan mandedepende ed elastic deformation na valve seat, no ag ingen sigpot ya mandedepende ed contact surface pressure na valve seat pian nadampot so sealing effect, Kanian say problema na zero leage na valve seat et naresolbe sakey a bekta, tan lapud say contact surface pressure et proporsyonal ed medium pressure, say atagey a pressure tan atagey a temperatura ya resistensya et mainomay met ya nasolbar.
