Introducere<\/p>\n
\u00cen compara\u021bie cu alte produse cu supape, robinetul de \u00eenalt\u0103 presiune al centralei electrice se caracterizeaz\u0103 prin temperatur\u0103 ridicat\u0103 \u0219i presiune \u00eenalt\u0103, design unic cu autoetan\u0219are, cu c\u00e2t presiunea este mai mare, cu at\u00e2t etan\u0219area este mai fiabil\u0103. Datorita performantelor deosebite, caracteristicilor tehnice si conditiilor de lucru, produsul a format caracteristici pe care alte produse nu le pot inlocui. Supapele cu poart\u0103 de \u00eenalt\u0103 temperatur\u0103 \u0219i presiune \u00eenalt\u0103 sunt utilizate \u00een principal \u00een conductele diferitelor sisteme din centralele termice pentru a \u00eentrerupe sau conecta mediile de conduct\u0103.<\/p>\n
Caracteristici structurale<\/p>\n
1. Supapele cu poart\u0103 de \u00eenalt\u0103 temperatur\u0103 \u0219i presiune \u00eenalt\u0103 pentru centrala electric\u0103 adopt\u0103 un canal de curgere avansat \u0219i o alt\u0103 structur\u0103 direct\u0103, care reduce foarte mult coeficientul de rezisten\u021b\u0103 la curgere \u0219i pierderea de energie \u0219i \u00eembun\u0103t\u0103\u021be\u0219te semnificativ durata de via\u021b\u0103 \u0219i performan\u021ba supapei.<\/p>\n
2. Cavitatea mijlocie a supapei adopt\u0103 o structur\u0103 de etan\u0219are cu auto-str\u00e2ngere la presiune, cu performan\u021be bune de etan\u0219are. Ambele capete ale conductei de ramifica\u021bie sunt structuri sudate.<\/p>\n
3. Suprafa\u021ba de etan\u0219are a pl\u0103cii supapei \u0219i a scaunului supapei este realizat\u0103 din aliaj dur pe baz\u0103 de stellit cobalt, care are o bun\u0103 rezisten\u021b\u0103 la uzur\u0103, rezisten\u021b\u0103 la temperaturi ridicate, rezisten\u021b\u0103 la coroziune \u0219i rezisten\u021b\u0103 la zg\u00e2rieturi.<\/p>\n
4. Dup\u0103 c\u0103lire \u0219i revenire \u0219i nitrurare a suprafe\u021bei, tija supapei are o bun\u0103 rezisten\u021b\u0103 la coroziune \u0219i rezisten\u021b\u0103 la zg\u00e2rieturi.<\/p>\n
5. Structura pieselor de deschidere \u0219i de \u00eenchidere poate fi proiectat\u0103 \u00eentr-o singur\u0103 pan\u0103, pan\u0103 dubl\u0103, pan\u0103 dubl\u0103 paralel\u0103 \u0219i alte forme \u00een func\u021bie de cerin\u021bele utilizatorului.<\/p>","protected":false},"excerpt":{"rendered":"

\n\u00b7 Pentru tipul de capot\u0103 cu etan\u0219are sub presiune:
\nGarnitura capotei trebuie s\u0103 fie de etan\u0219are metalic\u0103, inel RTJ \u2013 SS 304 pentru utilizare \u00eendelungat\u0103.
\nTija filetat\u0103 nu intr\u0103 \u00een contact cu mediul pentru a evita posibilitatea coroziunii.<\/p>\n
