It includes an evaporator ( 1 ), a condenser ( 2 ), a discharge valve ( 21 ), a vapor line ( 19 ), an electronically controlled throttle valve for gas ( 18 ), a main returning line ( 22 ), an electronically controlled throttle valve for liquid ( 23 ), an inter-returning line ( 24 ), a steam turbine ( 7 ).

1 . An equipment and method to generate electricity by drawing high temperature geothermal includes an evaporator ( 1 ), a condenser ( 2 ), a discharge valve ( 21 ), a vapor line ( 19 ), an electronically controlled throttle valve for gas ( 18 ), a main returning line ( 22 ), an electronically controlled throttle valve for liquid ( 23 ), an inter-returning line ( 24 ), a steam turbine ( 7 ); and
 there is a vapor outlet and a liquid inlet on the top of the evaporator ( 1 );   there is a vapor inlet and a vapor outlet on the steam turbine ( 7 );   there is a vapor inlet and a liquid outlet on the condenser ( 2 );   the vapor outlet on the evaporator ( 1 ) is connected with the vapor inlet on the steam turbine ( 7 ) through a vapor connecting line ( 20 ), which makes the vapor come into the steam turbine ( 7 );   an electronically controlled valve for gas ( 18 ) is installed in the vapor line ( 19 ) to adjust the vapor flow ( 13 );   the vapor outlet on the steam turbine ( 7 ) is connected with the vapor inlet on the condenser ( 2 ), which makes the vapor come into the condenser ( 2 ) after working in the steam turbine ( 7 );   there is a discharge valve ( 21 ) in the upper of the condenser ( 2 );   one end of a main returning line ( 22 ) is connected with the liquid outlet of the condenser ( 2 );   the other end of the main returning line ( 22 ) is connected with one end of an inter-returning line ( 24 );   an electronically controlled valve for liquid ( 23 ) is installed in the main returning line ( 22 ) to control the liquid flow ( 14 ) into the condenser ( 2 );   the other end of the inter-returning line ( 24 ) is inserted from the liquid inlet up to the bottom of the evaporator ( 1 ).   
     
     
         2 . An equipment and method to generate electricity by drawing high temperature geothermal according to  claim 1  wherein said evaporator ( 1 ) is made of metal and cylinder- or truncated right cone-shaped and is located underground zone with high temperature geothermal. 
     
     
         3 . An equipment and method to generate electricity by drawing high temperature geothermal according to  claim 1  wherein said condenser ( 2 ) and steam turbine ( 7 ) are done on the ground. 
     
     
         4 . An equipment and method to generate electricity by drawing high temperature geothermal according to  claim 1  wherein said the lines ( 19 ), ( 22 ) and ( 24 )are covered with the adiabatic materials. 
     
     
         5 . An equipment and method to generate electricity by drawing high temperature geothermal according to  claim 1  wherein said inter-returning line ( 24 ) is insert into the bottom of the evaporator ( 1 ). 
     
     
         6 . An equipment and method to generate electricity by drawing high temperature geothermal according to  claim 1  wherein said inter-returning line ( 24 ) bears with several rifling lines ( 25 ) on the inner surface and screw threads ( 26 ) on the outer surface, and the rotational directions of the rifling lines ( 25 ) and screw threads ( 26 ) are identical.
