Integrated Temperature and Pressure Reducing Device

An integrated pressure and temperature reducing device, comprising:

• a secondary steam pipe (1) and a temperature and pressure reduction mechanism disposed inside the secondary steam pipe (1), wherein
• the temperature and pressure reduction mechanism comprises an upper valve cover (4) and a valve core (5), the valve core (5) is provided thereon with a number of depressurization holes;
• a valve rod (9) is disposed at one end of the valve core (5), and one end of the valve rod (9) close to the valve core (5) is provided with a water delivery channel (9-1), and the valve rod (9) is provided, on an outer circumferential surface thereof, with a number of water inlet holes (9-2) in communication with the water delivery channel (9-1);
• a temperature reducing water pipe (10) is disposed at the other end of the valve core (5), one end of the temperature reducing water pipe (10) close to the valve rod (9) is provided with a drainage pipe (10-1), which is in communication with the water delivery channel (9-1), and a number of drainage holes (10-2) are provided on an outer circumferential surface of the temperature reducing water pipe (10) at one end of the temperature reducing water pipe (10) away from the valve core (5), the drainage holes (10-2) are in communication with the drainage pipe (10-1).
