Background technology
Ash valve is to be widely used in the industries such as metallurgy, electric power, mining industry, Coal Chemical Industry control high-temperature material changes in flow rate or cut off rapidly the device of flow；All there is valve body because of the problem of high temperature deformation in currently used high temperature sludge valve, after deformation, valve plate can not normally-open or closedown；And valve body is overheated, even " rubescent " is by the personal safety of serious threat to site operation personnel；Such as it is arranged on boiler slag removal pipeline, for controlling the valve of boiler slag removal；Existing Ash valve is when high-temperature material is by its inside, and the deformation of its valve plate is serious, and wearability is substantially reduced, and valve body superheating phenomenon is serious, has a strong impact on reliability and the safety of execute-in-place.
Summary of the invention
The present invention provides a kind of high temperature insulating Ash valve ensureing valve body wearability in the case of a high temperature and opening and closing motility.
The technical solution used in the present invention is: a kind of high temperature insulating Ash valve, including the outer valve of cylindrical structure and the inner valve body of cylindrical structure that is provided at its inner portion；It is provided with thermal insulating warm-keeping layer between outer valve inwall and inner valve body outer wall；Inner valve body is internally provided with the gathering sill along its center axis direction；Also include the valve plate that can slide along gathering sill.
Further, described inner valve body outer wall stretches out and forms inward flange outwardly, and outer valve inwall extends inwardly to form the outward flange coordinated with inward flange；Outward flange and inward flange contact surface are provided with thermal insulation layer.
Further, described inner valve body and valve plate adopt ZG8Cr33Ni9NRe type steel alloy.
Further, described thermal insulating warm-keeping layer adopts aluminosilicate fiber cotton.
Further, described valve plate connects handwheel by regulating valve stem.
Further, described regulating valve stem is fixed by the support being arranged on outer valve outer surface.
Further, the both sides packing matcrial of described inner valve body gathering sill.
The invention has the beneficial effects as follows:
(1) valve body of the present invention is divided into outer valve and inner valve body, is provided with thermal insulating warm-keeping layer and thermal insulation layer between inside and outside valve body, stops the temperature of inner valve body by conducting and radiation is delivered to outer valve, it is achieved that the low temperature of outer valve；
(2) inner valve body of the present invention and valve plate adopt ZG8Cr33Ni9NRe type steel alloy to make, and have good resistance to abrasion under worst hot case, simultaneously indeformable under high temperature, it is ensured that valve plate normally open and close function；
(3) outer valve temperature of the present invention is not high, is connected with external equipment and can directly adopt welding or bolt to connect, and whole device versatility is good, practical.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
In figure: 1-outer valve, 2-inner valve body, 3-valve plate, 4-thermal insulating warm-keeping layer, 5-thermal insulation layer, 6-regulating valve stem, 7-support, 8-handwheel.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
As it is shown in figure 1, a kind of high temperature insulating Ash valve, including the outer valve 1 of cylindrical structure and the inner valve body 2 of cylindrical structure that is provided at its inner portion；It is provided with thermal insulating warm-keeping layer 4 between outer valve 1 inwall and inner valve body 2 outer wall；Inner valve body 2 is internally provided with the gathering sill along its center axis direction；Also include the valve plate 3 that can slide along gathering sill.
Further, described inner valve body 2 outer wall stretches out and forms inward flange outwardly, and outer valve 1 inwall extends inwardly to form the outward flange coordinated with inward flange；Outward flange and inward flange contact surface are provided with thermal insulation layer 5.
Further, described inner valve body 2 and valve plate 3 adopt ZG8Cr33Ni9NRe type steel alloy.
Further, described thermal insulating warm-keeping layer 4 adopts aluminosilicate fiber cotton, have low heat conductivity, excellent heat stability and chemical stability, without binding agent and corrosive feature, calculate the thickness needed according to its heat conductivity；8-10cm thickness can ensure that the high temperature that can intercept 850～1000 DEG C under normal circumstances so that the temperature < of outer valve 1 outer surface 60 DEG C.
Further, described valve plate 3 connects handwheel 8 by regulating valve stem 6.
Further, described regulating valve stem 4 is fixed by the support 7 being arranged on outer valve 1 outer surface.
Further, the both sides packing matcrial of described inner valve body 2 gathering sill, encapsulant can also select aluminosilicate fiber cotton, ensures have sealing and heat insulation effect simultaneously；And aluminosilicate fiber cotton is a kind of flexible material, the both sides being filled in gathering sill not only can ensure that the motion of valve plate 3 but also can reach the effect sealed.
During use, handwheel 8 and regulating valve stem 6 are threaded connection；Rotating handwheel 8, drive the screw thread pair on handwheel 8 to rotate, the rotation with screw thread pair is become rectilinear motion by the regulating valve stem 6 being connected with this screw thread pair；Regulating valve stem 6 can drive connected valve plate 3 to move, and valve plate 3 will move along gathering sill direction in inner valve body 2, it is achieved the control action to material circulation；Because inner valve body 2 contacts with high-temperature material, when the whole inner valve body 2 of heating temperatures of high-temperature material, it is arranged between outer valve 1 inwall and inner valve body 2 outer wall to be provided with thermal insulating warm-keeping layer 4 and separates the heat transmitted to outer valve 1 with conduction of heat and radiation mode, so that outer valve 1 will not be heated, therefore whole device is while ensure that circulation high-temperature material keying effect, also achieves the function that outer valve 1 is not overheated；Being provided with thermal insulation layer 5 on outward flange and inward flange contact surface, the heat further having intercepted inner valve body 2 is outwards propagated；Inner valve body 2 and valve plate 3 adopt ZG8Cr33Ni9NRe type steel alloy, and work surface is through machining, and under worst hot case, this alloy has good corrosion resistance, meanwhile, indeformable under high-temperature condition ensure that valve plate 3 normally opens and closes function in inner valve body 2 gathering sill；Valve body is divided into inner valve body 2 and outer valve 1, thermal insulation layer 5 and thermal insulating warm-keeping layer is had additional between inside and outside valve body, prevent the temperature of inner valve body 2 by conducting and radiation is delivered on outer valve 1, achieving the low temperature of outer valve 1, surface is without overheated (< 60 DEG C), " rubescent " phenomenon；Packing matcrial in inner valve body 2, it is ensured that the seal of inner valve body 2, it is ensured that valve body is outer without leakage slag, leakage ash phenomenon；Outer valve 1 temperature is not high, therefore adopts carbon structure steel making conventional and with low cost, and its form being connected with external equipment may be produced that directly welding or bolt-connection, therefore whole device versatility is good, practical；The present invention is especially suitable for the Ash valve with heat insulating function in high temperature (850～1000 DEG C) situation.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within protection scope of the present invention.
