Description

Technical Field

[0001] The utility model relates to the technical field of temperature-reducing and pressure-reducing valves, in particular to a multi-stage pressure-reducing integrated temperature-reducing and pressure-reducing valve. Background Art

[0002] The temperature-reducing and pressure-reducing valve adjusts the flow rate of the medium by controlling the opening of the opening and closing parts in the valve body to reduce the pressure of the medium. At the same time, it adjusts the opening of the opening and closing parts with the help of the pressure behind the valve to keep the pressure behind the valve within a certain range, and sprays cooling water into the valve body or behind the valve to reduce the temperature of the medium. This valve is called a pressure-reducing and temperature-reducing valve.

[0003] At present, the announcement number CN216131394U discloses an integrated temperature-reducing and pressure-reducing valve, including a valve body, an upper valve cover, a lower valve cover, a lower flange, an upper sleeve, a lower sleeve, a pressure-reducing sleeve, a nozzle, a valve stem, a small valve core, a valve core gland, a large valve core, and a valve seat. The solution provided by the utility model is based on a pilot-type balanced structure and adopts a multi-stage pressure-reducing principle. By drilling holes at the flow positions of the pressure-reducing sleeve, the large valve core, and the lower sleeve, the fluid can be pressure-reduced in multiple stages; after the pressure is reduced, the temperature of the steam is reduced by the temperature-reducing water atomized from the nozzle, thereby realizing a pilot-type multi-stage pressure-reducing integrated temperature-reducing and pressure-reducing valve.

[0004] In order to solve the problem of cooling and reducing pressure, the existing technology adopts the principle of multi-stage pressure reduction. By drilling holes in the flow positions of the pressure reduction sleeve, the large valve core, and the lower sleeve, the fluid can be reduced in multiple stages; after the pressure is reduced, the temperature of the steam is reduced by cooling water atomized from the nozzle. However, when the device is used for a long time, there will be a problem that the pipeline is clogged due to a large number of impurities, which leads to the problem of poor internal transmission effect.
