[0014] (III) Beneficial Effects

[0015] This utility model provides a multi-stage throttling desuperheater and pressure reducer, which has the following beneficial effects:

[0016] 1. This multi-stage throttling desuperheater and pressure reducer, through the setting of the cooling components, connects the flow pipe to the external cold water pipe during use. The external cold water enters the interior of the inlet pipe through the flow pipe, and multiple sets of flow control valves are opened in sequence. The cold water enters the interior of the desuperheater and pressure reducer body through the inlet pipe in sequence, thereby cooling it multiple times. This can avoid the problem of excessive single-stage water spray volume causing localized overcooling of steam or incomplete evaporation of water droplets. It achieves multiple step-by-step reductions in steam temperature and pressure, thereby ensuring the safe, stable and efficient operation of the system.

[0017] 2. This multi-stage throttling desuperheater and pressure reducer, through the setting of the sealing components, when connected, the flange squeezes the gasket, causing the compression spring to be in a compressed state. The compression spring exerts a force on the gasket, making the gasket fit tightly against the flange. The return spring supports the gasket, making the gasket fit tightly against the inside of the flange. This ensures a tight fit between the gasket and the flange, ensuring a good sealing effect during flange connection and preventing steam or water leakage from the interface.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: a multi-stage throttling desuperheating and pressure reducing device, including a desuperheating and pressure reducing device body 1, a cooling component 2 fixedly connected to one side of the desuperheating and pressure reducing device body 1, the device can achieve step-by-step cooling through the setting of the cooling component 2, a number of flanges 3 fixedly connected to the outside of the desuperheating and pressure reducing device body 1, and a sealing component 4 fixedly connected to one side of each of the number of flanges 3, the sealing component 4 prevents steam or water from leaking out from the interface, the cooling component 2 includes a number of water inlet pipes 201 fixedly connected to one side of the desuperheating and pressure reducing device body 1, a flow control valve 202 is set on the outside of each of the number of water inlet pipes 201, and a flow pipe 203 is fixedly connected to one side of each of the number of water inlet pipes 201; the sealing component 4 includes a number of compression springs 401 fixedly connected to one side of each of the number of flanges 3, a sealing gasket 402 fixedly connected to one side of each of the number of compression springs 401, and a return spring 403 is set inside each of the number of sealing gaskets 402.

[0025] The outer side of the desuperheater and pressure reducer body 1 is provided with a sound insulation layer 5. One end of the flow pipe 203 is connected to the external cold water pipe. The sound insulation layer 5 reduces the noise generated by the device.

[0026] Several sets of flanges 3 are fixedly connected to the bottom surface of each set of flanges 3. Several sets of flanges 6 are provided with threaded holes on their surfaces. Several sets of flanges 6 are provided with threaded bolts 7 inside their threads. The support legs 6 are used to support the device.

[0027] The top surface of the desuperheating and pressure reducing device body 1 is fixedly connected to the mounting pipe 8, and the top surface of the mounting pipe 8 is fixedly connected to the connecting plate 9. The connecting plate 9 serves to install the desuperheating and pressure reducing valve 10.

[0028] A desuperheating and pressure reducing valve 10 is fixedly connected to the top surface of the connecting plate 9. The desuperheating and pressure reducing valve 10 is equipped with a regulating valve 11. The regulating valve 11 is used to regulate the water flow rate.

[0029] Two sets of support rods 12 are fixedly connected to the top surface of the de-cooling and pressure reducing device body 1. Pressure gauges 13 are installed on the top surface of both sets of support rods 12. The pressure gauges 13 are used to detect the internal pressure of the device.

[0031] In this invention, the working steps of the device are as follows:

[0032] First step: When in use, connect the flow pipe 203 to the external cold water pipe, etc. The external cold water enters the interior of the inlet pipe 201 through the flow pipe 203. Open multiple sets of flow control valves 202 in sequence, and the cold water enters the interior of the desuperheater and pressure reducer body 1 from the inlet pipe 201 in sequence, thereby cooling it multiple times.
