Abstract

The present invention belongs to the field of energy saving and comprehensive heat energy utilizing technology. The steam temperature and pressure lowering apparatus has electric executing mechanism connected to temperature and pressure lowering valve, temperature lowering water flow regulating valve connected to the temperature lowering water atomizer, and temperature, pressure and flow rate regulating system connected to the electric executing mechanism. It features the casing of the temperature and pressure lowering valve with water inlet pipe, hollow rod capable of sliding axially inside the casing, and casing pipe around the hollow rod. The hollow rod has tangent holes corresponding to the exit of the water inlet pipe, is connected to the electric executing mechanism and has one end connected with one cage type valve core, which has porous wall and is matched with steam inlet valve jacket in porous structure.

Description

technical field [0001] The invention relates to a temperature and pressure reduction device for a steam supply system, which belongs to the technical field of energy saving and heat energy comprehensive utilization equipment manufacturing. Background technique [0002] Currently known steam temperature reduction and pressure reduction devices used in steam supply systems use throttling of steam fluid to reduce steam pressure, and spray water into steam to achieve temperature reduction. Although a specially designed decompression and cooling system is used, there are problems of complex structure and complicated system. The high-energy jet generated in throttling is not only not effectively utilized, but often causes erosion and damage to the structure with its high-intensity energy. Vibration and noise, the process of cooling and spraying water is often due to the defects of the existing design, the atomization effect is not good when the device is under low load, there are ...
