Abstract
The invention discloses a self-cooling and high-temperature-resistant valve. The self-cooling and high-temperature-resistant valve comprises a flashboard sleeve and a valve flashboard. The two sides of the flashboard sleeve are provided with holes used for making two fluid pipelines communicate with each other. The valve flashboard is inserted in the flashboard sleeve in a clearance fit mode. The valve flashboard is provided with a lifting-pulling device and is a hollow shell. Through a separation plate arranged in the valve flashboard, an inner cavity of the valve flashboard is divided into two parts communicating with each other. The valve flashboard is provided with two valve steel pipes communicating with the two parts of the inner cavity of the valve flashboard correspondingly. A cooling medium enters the valve flashboard from one valve steel pipe and flows out from the other valve steel pipe after taking away heat of high-temperature fluid. The self-cooling and high-temperature-resistant valve is simple in structure, convenient to operate and use, resistant to high temperatures, good in sealing property, low in manufacturing and running cost, capable of achieving industrial production, and suitable for being used for controlling passing conditions of the high-temperature fluid.
Description
Technical field

Background technology
The water of High Temperature High Pressure such as thermal power plant, petrochemical industry, metallurgy, steam, oil product, superheated steam, more than 300 DEG C high-temperature flue gas pipeline on, generally to use hot-resistant valve and be switched off or on medium. Hot-resistant valve conventional at present has: 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 some problems in actual use in these hot-resistant valves.
(1) although stainless steel high temperature butterfly valve has, conveniently opening and closing is rapid, laborsaving, fluid resistance is little, can often operate, simple in construction, the advantages such as volume is little, and lightweight, adjustment performance is good, but this valve uses pressure and operating temperature range is little, sealing property is also poor;
(2) high-temperature electromagnetic valve core is rustless steel piston type, piston ring Special temperature resistant, high-abrasive material make, and piston and metal valve pocket do not produce direct friction, and valve body installation direction is unrestricted, special coil, and adopt the frame mode of heat radiation, and therefore not easily to burn, long-time stopping action restarting, action is sensitive equally, lowest starting pressure is low, but the structure of this valve is complicated, and manufacturing cost is high;
(3) elastic ball ball valve can be high temperature resistant, but owing to spheroid and valve seat insert all adopt metal material manufacture, seal pressure is very big, relies on the pressure of medium itself not reach seal request, it is necessary to rely on external force;
(4) cast steel gate valve has fluid resistance little, sealing surface is little by washing away and corroding of medium, opening and closing is relatively labor-saving, medium flows to unrestricted, not flow-disturbing, do not reduce pressure, simple in construction, structure length is short, anufacturability is simple, high-temperature-resistant high-pressure-resistant can material selection many, the advantage such as applied widely, but easily cause erosion and scratch between the sealing surface of cast steel gate valve, keep in repair relatively difficult.
Summary of the invention
The technical purpose of the present invention be in that to overcome existing hot-resistant valve resistance to temperature do not reach particular requirement, circulation area and flow are little, manufacturing cost is high deficiency and provide a kind of simple in construction, 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 the following technical scheme that realization: a kind of self cooling hot-resistant valve, including flashboard set and valve flashboard, described flashboard overlaps two STHs for connecting two sections of fluid lines, described valve flashboard employing matched in clearance is inserted in described flashboard set and is separated by two STHs that flashboard overlaps, and described valve flashboard is provided with pulling apparatus; Described valve flashboard is hollow shell, inside is provided with a dividing plate and valve flashboard inner chamber is divided into the two parts being interconnected, described valve flashboard is provided with two valve steel pipes and is respectively communicated with the inner chamber of two part valve flashboard, cooling gas or liquid are entered flashboard inner chamber by one of them valve steel pipe, are gone out by another valve steel pipe flow after taking away the heat of high temperature fluid.
Preferred version as the present invention, described flashboard set the latter half is cuboid perforate on two sides that it is relative, corresponding cuboid valve flashboard is inserted in described flashboard set, it is cylinder flashboard set that described flashboard overlaps the first half, described valve flashboard upper end is provided with downward opening cylinder sluice cover plate spiral-lock on described cylinder flashboard overlaps, it is provided with sealing ring between described cylinder flashboard set and cylinder sluice cover plate and realizes mobile sealing, this is wherein, the internal diameter of described cylinder flashboard set is more than or equal to the catercorner length of described cuboid valve flashboard cross section.For ensureing the sealing when mobile of the sluice cover plate, the cross section of described sealing ring is upper and lower two tapers, and wherein conical tapers upward is less than the tapering towards inferior pyramidal.
In the present invention, described flashboard overlaps two STHs and arranges two sections of connection pipelines, and described connection pipeline one end is welded with flashboard set and is connected, and the other end is provided with the pipe flange for being connected in pipeline.
In the present invention, described pulling apparatus is suspension ring, can pass through mechanically or manually lift valve flashboard and control the aperture of valve flashboard, thus controlling flow.
Flashboard set and valve flashboard in the present invention all adopt high temperature resistant stainless steel to make, high temperature resistant stainless steel refer to use temperature not aoxidize at 1080 DEG C throughout the year, indeformable, resistance to " chlorine root " corrodes, the maximum operation (service) temperature stainless steel material up to 1100 DEG C.
The operation principle of the present invention is as follows: when high temperature fluid flows through self cooling hot-resistant valve, the aperture of valve is controlled by manipulating the suspension ring on valve flashboard, thus controlling the flow of high temperature fluid, when valve flashboard rises, aperture increases, and high temperature fluid flow becomes big, when valve flashboard declines, aperture reduces, and flow diminishes. Owing to this valve flashboard is hollow, its inner chamber is divided into two parts by dividing plate, cooling medium is entered by a valve steel pipe, the long period can be detained by intracavity in flashboard, such that it is able to carry out a degree of heat exchange with high temperature fluid, after last cooling medium absorbs certain heat, temperature raises, outlet stainless steel tube discharge, thus reaching certain fluid cooling effect.
The present invention adopts high temperature resistant stainless steel control to make, can be high temperature resistant, the long service life of valve. Additionally the gap between flashboard set and valve flashboard is only small, and between sluice cover plate, sealing ring is set, not easily reveal when high temperature fluid flows through, good sealing effect, contrast above-mentioned hot-resistant valve, present configuration is simple, easy for operation, high temperature resistant, good seal performance, manufacture and operating cost low, it may be achieved industrialized production, be adapted as control high temperature fluid used by situation.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
