[0004] 1. When the existing temperature and pressure reducing valve is in use, when the outlet pressure needs to be increased, the area of the flow channel will be increased, and the outlet pressure will increase instantaneously, and it is impossible to slowly adjust the outlet pressure to increase or decrease;
[0005] 2. When the existing temperature and pressure reducing valve is in use, it is impossible to mechanically mix the steam and the cooling water, but simply make the steam and the cooling water mix automatically, and the cooling effect of the steam is not obvious;

Embodiment
[0041] Example: such as Figure 1 to Figure 10 As shown, the present invention provides the following technical solutions for steam system atomization integrated temperature and pressure reduction device, the temperature and pressure reduction device includes a valve body 1, a steam inlet pipe 2 is provided at one end of the valve body 1, and a The steam outlet pipe 3 is provided with a valve seat 4 inside the valve body 1, a valve core 5 is provided on the valve seat 4, and a decompression assembly 6 is provided under the valve seat 4. The steam pressure inside the body 1 is reduced so that the steam is output from the steam outlet pipe 3 at a certain pressure value. The cooling water pipe 7 is arranged at the bottom of the valve body 1, and the desuperheating assembly 8 is arranged under the decompression assembly 6. The desuperheating assembly 8 is used for To lower the temperature of the steam entering the valve body 1 through the steam inlet pipe 2, so that the steam is o...

The invention discloses an integrated temperature and pressure reduction device for steam system atomization, and relates to the technical field of temperature and pressure reduction valves. A valve core is arranged on the valve seat, and a pressure reduction component is arranged under the valve seat. The decompression assembly includes an inner throttling grille, an outer throttling grille, a first throttle hole and a second throttling hole. The inner throttling grille can be rotated by opening and closing the spool. Then realize the adjustment of the relative position of the first orifice and the second orifice. When the valve core is opened, there will be a misalignment between the first orifice and the second orifice. At this time, the flow path can be adjusted. The incoming steam is blocked, thereby reducing the pressure of the steam, and the larger the opening of the flow channel, the more obvious the blocking effect on the steam. When the pressure is adjusted, the pressure of the steam changes instantaneously, causing accidents.
Description
technical field [0001] The invention relates to the technical field of temperature and pressure reduction valves, in particular to an integrated temperature and pressure reduction device for steam system atomization. Background technique [0002] The temperature and pressure reducing valve is to keep the pressure and temperature at the outlet within a certain range when the inlet pressure is constantly changing. The pressure reducing valve is an essential part of the pneumatic control valve. The pressure is stabilized to a fixed value, so that the regulating valve can obtain stable air source power for regulating control; [0003] The existing temperature and pressure reducing valves have the following problems in use: [0004] 1. When the existing temperature and pressure reducing valve is in use, when the outlet pressure needs to be increased, the area of the flow channel will be increased, and the outlet pressure will increase instantaneously, and it is impossible to s...
