Robinetele fluture nu sunt utilizate pe scar\u0103 larg\u0103 numai \u00een industriile generale, cum ar fi petrolul, gazele, produsele chimice, tratarea apei, dar \u0219i \u00een sistemul de r\u0103cire cu ap\u0103 al centralelor termice. Placa \u0219i flan\u0219\u0103 sunt dou\u0103 metode de conectare. Supapa fluture cu flan\u0219\u0103 are flan\u0219e la ambele capete ale corpului supapei, care sunt conectate cu flan\u0219e de \u021beav\u0103. Corpul supapei fluture tip wafer nu are flan\u0219e la ambele capete, doar c\u00e2teva g\u0103uri pentru \u0219uruburi pilot, iar supapa este conectat\u0103 cu flan\u0219ele la capete cu un set de \u0219uruburi\/piuli\u021be. Clip-on-ul este ieftin \u0219i u\u0219or. Atunci c\u00e2nd alege\u021bi supape importate, utiliza\u021bi pe c\u00e2t posibil tipul de napolitan\u0103, ceea ce este ieftin.
\nSupap\u0103 tip wafer<\/a> \u0219uruburile sunt lungi \u0219i necesit\u0103 o precizie mai mare de construc\u021bie. Dac\u0103 flan\u0219ele de pe ambele p\u0103r\u021bi sunt nealiniate, \u0219uruburile vor fi supuse unei for\u021be de forfecare mai mari \u0219i supapa se va scurge cu u\u0219urin\u021b\u0103.<\/p>\n

\u00cen schimb, supapa fluture de napolitan\u0103 este mai u\u0219or de dezasamblat, iar costul supapei este mai mic, dar dezavantajul este c\u0103 exist\u0103 o problem\u0103 cu o suprafa\u021b\u0103 de etan\u0219are \u0219i ambele suprafe\u021be de etan\u0219are trebuie dezasamblate.<\/p>\n

Garniturile supapelor fluture cu flan\u0219\u0103 sunt relativ mai fiabile, dar costul supapei este relativ mare.<\/p>\n

Mai mult dec\u00e2t at\u00e2t, supapa fluture tip wafer, \u00een general, nu poate fi utilizat\u0103 la cap\u0103tul conductei \u0219i acolo unde trebuie dezasamblat\u0103 aval, deoarece atunci c\u00e2nd flan\u0219a din aval este dezasamblat\u0103, supapa tip wafer va c\u0103dea. \u00cen acest caz, trebuie f\u0103cut\u0103 o alt\u0103 \u00eembinare scurt\u0103. Este u\u0219or de dezasamblat, iar supapa fluture cu flan\u0219\u0103 nu are problemele de mai sus, dar costul va fi relativ mare.<\/p>\n

\u0218uruburile supapelor de tip wafer sunt \u00een general relativ lungi. \u00cen condi\u021bii de temperatur\u0103 ridicat\u0103, expansiunea \u0219uruburilor poate provoca scurgeri, deci nu este potrivit pentru diametre mari de \u021bevi \u00een condi\u021bii de temperatur\u0103 ridicat\u0103.<\/p>\n

\"Wafer

Supapa fluture de tip Wafer este plasat\u0103 \u00eentre flan\u0219ele conductei, iar \u0219uruburile flan\u0219ei \u00eenconjoar\u0103 corpul supapei. Supapa fluture tip wafer este potrivit\u0103 pentru majoritatea flan\u0219elor (inclusiv Tabelul E, PN16 \u0219i Ansi150). Dac\u0103 oricare parte a supapei necesit\u0103 \u00eentre\u021binere, atunci \u00eentreaga linie trebuie oprit\u0103.<\/p><\/div>\n

Butterfly valves are not only widely used in general industries such as petroleum, gas, chemical, water treatment, but also in the cooling water system of thermal power plants. Wafer and flange are two connection methods. Flanged butterfly valve has flanges at both ends of the valve body, which are connected with pipe flanges.
