Abstract

Dispositivo di chiusura di sicurezza ad autoazionamento termico per linee o apparecchiature alimentate da gas combustibile comprendente un corpo principale sostanzialmente cilindrico dotato alle proprie estremità di idonei raccordi per l'inserimento sulla linea di alimentazione del gas e ulteriormente provvisto di un alesaggio terminante in una sede di tenuta e portante inserito un elemento fusibile su cui appoggia un pistoncino metallico di chiusura caricato da una molla, in modo che l'elemento fusibile, provvisto di scanalature radiali, agisca da distanziatore impedendo la chiusura della sede di tenuta ad opera del pistoncino di chiusura sospinto dalla molla di carico e consentendo quindi il libero flusso del gas, elemento fusibile che, in caso di esposizione ad una temperatura predeterminata, fonde permettendo al pistoncino di raggiungere e chiudere la sede impedendo così qualsiasi ulteriore uscita di gas.Thermal self-closing safety closing device for lines or equipment fueled by combustible gas comprising a substantially cylindrical main body equipped at its ends with suitable fittings for insertion on the gas supply line and further provided with a bore ending in a seat of seal and carrier inserted a fusible element on which rests a metal closing piston loaded by a spring, so that the fusible element, provided with radial grooves, acts as a spacer preventing the sealing seat from closing by the pushed closing piston from the load spring and thus allowing the free flow of gas, a fusible element which, in case of exposure to a predetermined temperature, melts allowing the piston to reach and close the seat thus preventing any further gas outlet.
