Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
As Fig. 1,4, a kind of water-cooled valve stand structure of 1500 DEG C of superhigh temperature valves, comprise valve seat 1 and valve base 6, described valve seat 1 is made up of normal flow passage area 2 and sealing surface of seat region 3, the outer circumferential face of this normal flow passage area 2 evenly arranges straight trough road 4, arrange gradual change conduit 5 at the outer circumferential face in sealing surface of seat region 3, this gradual change conduit 5 head rounding off to connect after described straight trough road 4 end rearwardly gradual change and expands; Described valve seat 1 is installed on valve base 6 and makes the conduit sealing on valve seat 1 outer surface form water-cooled runner; Described valve base 6 is provided with water-cooled and imports and exports runner, this water-cooled import and export runner respectively and water-cooled runner and straight trough road head and gradual change conduit afterbody through and to form between valve seat and valve base independently cooling water recirculation system.
As shown in Fig. 3-1,3-2,3-3, valve seat of the present invention adopts straight trough road to add gradual change channel structure, forms current dispersal device by being combined with valve base.In the normal flow passage area of valve, the tank of valve seat is straight trough road, and cooling water can flow rapidly uniformly, for this region provides enough and applicable heat exchange value.In sealing surface of seat region, the tank of valve seat is gradual change conduit taper conduit in other words.The straight trough road of this gradual change conduit and normal flow passage area forms certain taper, expands water flow; Thus achieve the high heat exchange value in this region, finally ensure that the reliable sealing of valve, and larger thermal loss can not be formed because of water cooling plant.For reaffirming the feasibility of this valve seat, we are by heat transfer heating power comparing calculation: establish gradual change conduit head to be wider than 13mm, when afterbody is wider than 19mm, zirconium copper liner maximum temperature 690K herein, higher than maximum operation temperature 480K! Gradual change conduit head is wide is less than 10mm, and afterbody is wide when being less than 16.5mm, zirconium copper liner maximum temperature 700K herein, higher than maximum operation temperature 480K! Thus drawing the wide 11.6mm of gradual change conduit head, during afterbody wide 17.2mm, valve seat can safe and reliable operation under the operating mode of 1500 DEG C of superhigh temperature.
As shown in Fig. 2-1,2-2,2-3, described water-cooled inlet channel 7, water-cooled outlet flow 8 respectively by import buffer area 9, outlet buffer area 10 and water-cooled runner and straight trough road head and gradual change conduit afterbody through.The setting of inlet/outlet buffer area 9,10 can make entery and delivery port hydraulic pressure steady, the inflow of uniform fluid flow, goes out valve seat conduit, ensure that uniformity and the reliability of heat radiation.
As in Figure 2-4, uniform four water intakes on cylindrical bottom described valve base 6, and the same side of its top cylindrical is arranged and the water outlet of water intake equal number.Adopt valve of the present invention horizontal positioned on device, when cooling water is by existing a small amount of gasification phenomenon during valve seat conduit; Being arranged on the top position, the same side of this circumference of water outlet, makes the water vapour very first time discharge with water outlet; Thus ensure that the pressure stability of valve seat integral channel, water vapor is not saved bit by bit in valve seat inner.
Working procedure of the present invention: first, cooling water flows in valve base 6 by water-cooled inlet channel 7, collects rapidly, enter valve seat 1 in valve base 6 import buffer area 9.The normal flow passage area of valve due to valve seat 1 is evenly equipped with straight trough road, makes the cooling water uniform normal flow passage area by valve rapidly.Then, when cooling water enters sealing surface of seat region 3, because valve seat 1 outer circumferential face is designed with gradual change conduit, cooling water is disperseed uniformly according to conduit angle of taper, large-scale cooling water can reduce sealing surface temperature rapidly, thus makes the usefulness of sealing surface place cooling water perform to greatest limit; Ensure that the sealability of sealing surface of seat, for the sealing of valve provides reliable guarantee.Finally, cooling water enters valve base outlet buffer area 10, flows to outlet end, realizes the cyclical effect of whole constituent, thus reach the application target of valve seat water-cooled by valve base 6.
