Abstract

The invention relates to the technical field of valve manufacturing, in particular to an integrated temperature and pressure reduction device, which includes a secondary steam pipeline and a temperature and pressure reduction mechanism arranged in the secondary steam pipeline. The temperature and pressure reduction mechanism includes an upper valve cover And the spool, the spool is provided with a number of pressure-reducing holes, one end of the spool is inserted with a valve stem, and the end of the valve stem close to the spool is provided with a water delivery channel, and the outer peripheral surface of the valve stem is provided with a number of water delivery channels. The other end of the valve core is inserted with a desuperheating water pipe, the end of the desuperheating water pipe close to the valve stem is provided with a water outlet, the outlet channel is connected with the water delivery channel, and the outer peripheral surface of the end of the desuperheating water pipe far away from the valve core is provided with a There are several water outlet holes, and the water outlet holes are connected with the water outlet. The invention increases the contact area between the primary steam and the desuperheating water, ensures a good temperature and decompression effect, high adjustment accuracy, and compact structure.

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 ...
