On the pipeline of the water of the High Temperature High Pressure such as thermal power plant, petrochemical industry, metallurgy, steam, oil product, superheated vapor, more than 300 ℃ high-temperature flue gas, conventionally to use hot-resistant valve and cut off or connect medium.Conventional hot-resistant valve has at present: stainless steel high temperature butterfly valve, high-pressure solenoid valve, elastic ball ball valve, cast steel gate valve etc.All more or less there are in actual use some problems in these hot-resistant valves.
(1) although, stainless steel high temperature butterfly valve has that open-close convenient is rapid, laborsaving, fluid resistance is little, can often operate, simple in structure, the advantages such as volume is little, and lightweight, adjusting function is good, but this valve working pressure and operating temperature range is little, sealability is also poor;
(2), high-temperature electromagnetic valve core is stainless steel piston type, for piston ring, Special temperature resistant, high-abrasive material are made, and piston and metal valve pocket do not produce direct friction, and valve body installation direction is unrestricted, handtailor coil, and adopt the mode of structure dispelling the heat, and be therefore difficult for burning, stop for a long time action and restart, move sensitive equally, lowest starting pressure is low, but the complex structure of this valve, manufacture cost is high;
(3), elastic ball ball valve can be high temperature resistant, but because spheroid and valve seat insert all adopt metallic material manufacture, seal pressure is very large, relies on the pressure of medium itself not reach seal request, must dependence external force;
(4), cast steel gate valve has fluid resistance little, sealing surface be subject to washing away of medium and corrode little, open and close more laborsaving, MEDIA FLOW to unrestricted, not flow-disturbing, do not reduce pressure, simple in structure, structure length is short, anufacturability is simple, and high-temperature-resistant high-pressure-resistant is can material selection many, the advantage such as applied widely, but between the sealing surface of cast steel gate valve, easily cause erosion and scratch, keep in repair more difficult.
Summary of the invention
Technical purpose of the present invention is to overcome existing hot-resistant valve institute heatproof degree and does not reach the deficiency that particular requirement, circulation area and flow are little, manufacture cost is high and provide a kind of simple in structure, easy for operation, high temperature resistant, good seal performance, manufacture and operating cost is low, can realize the self cooling hot-resistant valve of industrialized production.
The present invention adopts following technological scheme to realize: a kind of self cooling hot-resistant valve, comprise flashboard cover and valve flashboard, described flashboard overlaps two STHs for being communicated with two sections of fluid lines, described valve flashboard employing Spielpassung is inserted in described flashboard cover two STHs of flashboard cover is separated, and described valve flashboard is provided with stretching device; Described valve flashboard is hollow shell, inside is provided with a dividing plate and valve flashboard inner chamber is divided into the two-part that are interconnected, described valve flashboard is provided with the inner chamber that two valve steel pipes are communicated with respectively two part valve flashboard, cooled gas or liquid enter flashboard inner chamber by one of them valve steel pipe, are flowed out after taking away the heat of high temperature fluid by another valve steel pipe.
As preferred version of the present invention, described flashboard cover lower half portion is cuboid perforate on its two relative sides, corresponding cuboid valve flashboard is inserted in described flashboard cover, described flashboard cover upper half part is cylindrical body flashboard cover, described valve flashboard upper end is provided with downward opening cylindrical body sluice cover plate spiral-lock and puts at described cylindrical body flashboard, between described cylindrical body flashboard cover and cylindrical body sluice cover plate, be provided with seal ring and realize hydrodynamic reciprocating sealing, this wherein, the internal diameter of described cylindrical body flashboard cover is more than or equal to the catercorner length of described cuboid valve flashboard cross section.For guaranteeing the sealing of sluice cover plate when mobile, the cross section of described seal ring is upper and lower two tapers, and wherein taper tapering is upward less than the tapering towards inferior pyramidal.
In the present invention, described flashboard overlaps two STHs and two sections of connecting tubes is set, and described connecting tube one end and the welding of flashboard cover are connected, and the other end is provided with for being connected to the piping flange of pipeline.
In the present invention, described stretching device is suspension ring, can or manually lift the aperture of valve flashboard control valve flashboard by machinery, thereby control flow.
Flashboard in the present invention cover and valve flashboard all adopt high temperature resistant stainless steel to make, high temperature resistant stainless steel refer to long-term serviceability temperature at 1080 ℃, be not oxidized, indeformable, resistance to " chlorine root " corrosion, maximum operation (service) temperature can reach the stainless steel material of 1100 ℃.
Working principle of the present invention is as follows: when high temperature fluid flows through self cooling hot-resistant valve, by controlling suspension ring on valve flashboard, carry out the aperture of control valve, thereby control the flow of high temperature fluid, when valve flashboard rises, aperture increases, and it is large that high temperature fluid flow becomes, when valve flashboard declines, aperture reduces, and flow diminishes.Because this valve flashboard is hollow, its inner chamber is divided into two-part by dividing plate, cooling medium is entered by a valve steel pipe, can in flashboard inner chamber, be detained the long period, thereby can carry out heat exchange to a certain degree with high temperature fluid, after last cooling medium has absorbed certain heat, temperature raises, and is discharged, thereby reach certain fluid cooling effect by outlet Stainless Steel Tube.
The present invention adopts high temperature resistant stainless steel pipe manufacturer, can be high temperature resistant, and the long service life of valve.Gap between flashboard cover and valve flashboard is very little in addition, and between sluice cover plate, seal ring is set, when flowing through, high temperature fluid is difficult for revealing, good sealing effect, contrast above-mentioned hot-resistant valve, the present invention is simple in structure, easy for operation, high temperature resistant, good seal performance, manufacture and operating cost low, can realize industrialized production, be suitable for using by situation as controlling high temperature fluid.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
