Heatable push rod for a steam turbine

The invention relates to an arrangement comprising a steam turbine (1) consisting of different sub-turbines (2a, 2b, 2c, 2d). Each sub-turbine (2a, 2b, 2c, 2d) has a rotor and a housing (15, 16), and during operation, a movement of one housing (15, 16) as a result of a thermal expansion of the rotor (12, 13) is followed, due to the rigid coupling of the housings by means of a push rod (17), by a movement of the other housing. The push rod (17) has a hollow design, and a thermal expansion is allowed by supplying the cavity with heated steam. The supply and discharge of the heated steam is regulated by the thermal expansion of the rotor (12, 13). 本发明涉及种装置，所述装置包括由不同的子涡轮机(2a，2b，2c，2d)构成的蒸汽轮机(1)，其中每个子涡轮机(2a，2b，2c，2d)具有转子和壳体(15，16)，其中在运行中，由于转子(12，13)的热膨胀，壳体(15，16)的运动通过壳体借助于推杆(17)的刚性联接来进行，其中推杆(17)空心地构成，并且通过供给空腔热蒸汽，热膨胀是可能的，其中热蒸汽的流入和流出的控制经由转子(12，13)的热膨胀来进行。
