Description
Technical field
The present invention relates to a kind of valving, particularly a kind of being suitable for controls the self cooling hot-resistant valve of high temperature fluid by situation.
Background technique
The water of the High Temperature High Pressure such as thermal power plant, petrochemical industry, metallurgy, steam, oil product, superheated vapor, more than 300 DEG C high-temperature flue gas pipeline on, usually to use hot-resistant valve and cut off or connect 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 that open-close convenient is rapid, laborsaving, fluid resistance is little, often can operate, structure is simple, the advantages such as volume is little, and lightweight, adjusting function is good, but this valve uses pressure and operating temperature range is little, sealability is also poor;
(2), high-temperature electromagnetic valve core is stainless 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, handtailor coil, and adopt the mode of structure of heat radiation, therefore not easily burn, long-time stopping action restarting, action is 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 all adopt metallic material manufacture due to spheroid and valve seat insert, and seal pressure is very large, relies on the pressure of medium itself not reach seal request, must 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 more laborsaving, MEDIA FLOW is to unrestricted, not flow-disturbing, do not reduce pressure, structure is simple, structure length is short, anufacturability is simple, the advantages such as high-temperature-resistant high-pressure-resistant alternate material is many, applied widely, but easily cause erosion and scratch between the sealing surface of cast steel gate valve, keep in repair more difficult.
Summary of the invention
Technical purpose of the present invention be to overcome existing hot-resistant valve resistance to temperature do not reach particular requirement, circulation area and flow are little, manufacture cost is high deficiency and provide that a kind of structure is simple, 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 and is separated by two STHs that flashboard overlaps, 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 be interconnected, described valve flashboard is provided with the inner chamber that two valve steel pipes are communicated with two part valve flashboard respectively, 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 overlaps lower half portion and is cuboid and perforate on two sides that it is relative, corresponding cuboid valve flashboard is inserted in described flashboard cover, the described flashboard cover first half is divided into cylindrical body flashboard cover, described valve flashboard upper end is provided with downward opening cylindrical body sluice cover plate spiral-lock on described cylindrical body flashboard cover, be provided with seal ring between described cylindrical body flashboard cover and cylindrical body sluice cover plate 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 ensureing the sealing when mobile of sluice cover plate, the cross section of described seal ring is upper and lower two tapers, and wherein conical tapers is upward less than the tapering towards inferior pyramidal.
In the present invention, described flashboard overlaps two STHs and arranges two sections of connecting tubes, and described connecting tube one end is overlapped to weld with flashboard and is connected, and the other end is provided with the piping flange for being connected in pipeline.
In the present invention, described stretching device is suspension ring, by machinery or the artificial aperture lifting valve flashboard control valve flashboard, thus controls flow.
Flashboard cover in the present invention and valve flashboard all adopt high temperature resistant stainless steel to make, and high temperature resistant stainless steel refers to that long-term serviceability temperature is not oxidized at 1080 DEG C, indeformable, and resistance to " chlorine root " corrodes, and maximum operation (service) temperature can reach the stainless steel material of 1100 DEG C.
Working principle of the present invention is as follows: when high temperature fluid flows through self cooling hot-resistant valve, the aperture of control valve is carried out by the suspension ring on manipulation valve flashboard, thus control the flow of high temperature fluid, when valve flashboard rises, aperture increases, and high temperature fluid flow becomes large, 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, the long period can be detained in flashboard inner chamber, thus the heat exchange can carrying out to a certain degree with high temperature fluid, after last cooling medium absorbs certain heat, temperature raises, and is discharged, thus 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, the long service life of valve.Gap in addition between flashboard cover and valve flashboard is very little, and between sluice cover plate, seal ring is set, not easily reveal when high temperature fluid flows through, good sealing effect, contrast above-mentioned hot-resistant valve, structure of the present invention is simple, easy for operation, high temperature resistant, good seal performance, manufacture and operating cost low, can industrialized production be realized, be suitable for as control high temperature fluid used by situation.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
