Beschreibung
Zusammenfassung:	A no-stress insulated valve group comprises a valve body, which is characterized in that an inner fixed section used to fix a work pipe and an outer thimble is arranged between the work pipe, the outer thimble of which are connected with the valve body; and the outer thimble is provided with a corrugated expansion joint. The utility model has the advantages that 1, because the work pipe and the outer thimble are fixed by the fixed section and a corrugated expansion joint is arranged on the outer thimble, when transporting high temperature steam, the work pipe and the outer thimble can not make a displacement at the valve, so the valve body is protected. 2, the installation and operation is simple, thus being beneficial to shorten construction cycle and reduce construction investment.
