Description

Technical Field

[0001] The utility model belongs to the technical field of temperature and pressure reducing devices, and more specifically, particularly relates to a temperature and pressure reducing device with a spring atomizing nozzle function. Background Art

[0002] The desuperheater and pressure reducer is a device that reduces high-temperature and high-pressure steam to low-pressure and low-temperature steam that customers can use. Taking the boiler superheater outlet as an example, the steam generated by the boiler passes through the superheater outlet to the steam turbine to perform work. The steam turbine has a range requirement for the parameters of the incoming steam. If the steam parameters at the superheater outlet exceed the upper limit required by the steam turbine, it will cause damage to the steam turbine.

[0003] Some current temperature and pressure reducers with spring atomizing nozzle function usually adjust the spray volume of the nozzle in a small range by adjusting the water flow rate through a regulating valve during temperature reduction. However, when the steam temperature is too high or too low, the spray volume of the nozzle needs to be adjusted in a large range. This method cannot solve the problem. At the same time, the water pipe connecting the spring atomizing nozzle is easily corroded and rusted due to the influence of high-temperature and high-pressure steam in the steam transportation pipeline for a long time, resulting in damage to the water pipe and inability to be used.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a temperature and pressure reducer with a spring atomizing nozzle function is provided, in order to achieve a more practical purpose. Utility Model Content

When the block moves to the top of the spring atomizing nozzle, it can block water from entering the spring atomizing nozzle below the block, thereby reducing the spray volume. Conversely, the operation can increase the spray volume, thereby enabling the spring atomizing nozzle to adapt to situations where the steam temperature is too high or too low.

[0016] By using the connecting block, connecting groove, clamping block, clamping groove, pulling block, transmission shaft and compression spring in coordination, first pull a pair of pulling blocks, the pulling block drives the transmission shaft to move outside the slide groove, so that the other end of the transmission shaft moves into the slide groove, at this time, insert the connecting block of protective shell one into the connecting groove of protective shell two, insert the clamping block of protective shell one into the clamping groove of protective shell two, release the pulling block, at this time, under the action of the compression spring, the compression spring pushes the other end of the transmission shaft into the groove through the limit block, and fixes the protective shell one and the protective shell two, and the protective shell one and the protective shell two can be quickly disassembled by the operation conversely, thereby achieving the effect of quick disassembly and installation, and at the same time, the water pipe one can be wrapped by the protective shell one and the protective shell two to protect the water pipe one, thereby preventing the water pipe one from being corroded and rusted by the influence of high temperature and high pressure steam for a long time, resulting in damage to the water pipe and making it unusable.
