Abstract

The invention relates to the technical field of manufacturing of valves, in particular to an integrated temperature-reducing and pressure-reducing device. The integrated temperature-reducing and pressure-reducing device comprises a secondary steam pipeline and a temperature-reducing and pressure-reducing mechanism, wherein the temperature-reducing and pressure-reducing mechanism is arranged in the secondary steam pipeline and comprises an upper bonnet and a valve element; a plurality of pressure-reducing holes are formed in the valve element; a valve rod is inserted in one end of the valve element; a water delivery channel is formed in one end, which is close to the valve element, of the valve rod; a plurality of water inlet holes which communicate with the water delivery channel are formed in an outer peripheral surface of the valve rod; a temperature-reducing water tube is inserted in the other end of the valve element; a water outlet channel is formed in one end, which is close to the valve rod, of the temperature-reducing water tube; the water outlet channel communicates with the water delivery channel; a plurality of water outlet holes are formed in an outer peripheral surface of one end, which is away from the valve element, of the temperature-reducing water tube; and the water outlet holes communicate with the water outlet channel. By the integrated temperature-reducing and pressure-reducing device, contact area of primary steam and temperature-reducing water is increased, good temperature-reducing and pressure-reducing effect is guaranteed, adjusting precision is high, and the structure is compact.

Description

technical field [0001] The invention relates to the technical field of valve manufacturing, in particular to an integrated temperature and pressure reduction device. Background technique [0002] The temperature and pressure reduction device is a steam thermal energy parameter conversion device and an energy-saving device that utilizes waste heat that are widely used in thermal engineering in modern industries such as cogeneration of heat and power, central heating or steam supply, and light industry, electric power, chemical, textile and other enterprises. , through the temperature and pressure reduction device, the steam parameters provided by the user are reduced to the temperature and pressure required by the user to meet the user's requirements, and can fully save heat energy and use heat energy reasonably. [0003] The contact area between the desuperheating water and the primary steam in the existing desuperheating and decompression device is small, which affects the ...
