摘要：PROBLEM TO BE SOLVED: To obtain a steam heating equipment made simple in its structure by dispersing with a plurality of valves being changeover means. SOLUTION: The jacket part 25 of a reaction vessel 20, a positive pressure discharge pipe 23 and an ejector type vacuum pump 24 are connected through a negative pressure/positive pressure changeover valve 22. The negative pressure/positive pressure changeover valve 22 has a fluid inlet 2, a negative pressure fluid outlet 4 and a positive pressure fluid outlet 5. When a negative pressure fluid flows in from the fluid inlet 2, it is discharged to the ejector type vacuum pump 24 from the negative pressure fluid outlet 4. When a positive pressure fluid flows in from the fluid inlet 2, it is discharged to a positive pressure discharge pipe 23 from the positive pressure fluid outlet 5. COPYRIGHT: (C)2004,JPO
