Abstract
The utility model discloses a metal high-temperature-shielding device special for a rupture disc and relates to the technical field of rupture discs. The device comprises an upper flange, a lower flange, bolts, a supporting frame, heat insulation plates, the rupture disc and a clamping device. The upper flange is fixedly connected with the lower flange through the bolts, the supporting frame is arranged between the upper flange and the lower flange, the heat insulation plates are installed on the upper face and the lower face of the supporting frame respectively, spot welding is performed on the periphery of the rupture disc after assembly, and then the rupture disc is arranged in the clamping device. The metal high-temperature-shielding device is reasonable in structural design, easy to operate and convenient and rapid to install, has the effects of high temperature resistance, corrosion resistance and good heat insulation, is free of environment pollution after rupturing, safe, reliable and capable of effectively guarantying rupturing pressure and meets the using requirements of people.
Description
Technical field
The utility model relates to a kind of rupture disk special-purpose metal high-temperature shielding device, belongs to rupture disk technical field.
Background technique
Rupture disk is the important safety of pressurized container, pipeline, and at the explosion temperature of regulation, rupture disk pressure at both sides is poor while reaching predetermined value, and rupture disk moves at once, breaks or comes off, and relieving pressure, ensures the safety of people's life and national wealth.Rupture disk is widely used in the fields such as chemical industry, oil, metallurgy, nuclear power, aviation.
Blasting piece device is comprised of rupture disk and clamp holder two-part.Rupture disk is at the element of demarcating explosion pressure release at bursting pressure and temperature, and clamp holder is the auxiliary element at the suitable position attaching clamping rupture disk of container.Thermal-protective material in current boiler industry before rupture disk is mainly mining industry cotton and ceramic fiber, and it is lightweight, heat-insulating property good, good thermal stability, easy processing, easy construction.But not wear-resisting also resistance to the touching not of this material, can not resist washing away of high velocity air, can not resist the erosion of slag, the serviceability temperature of rupture disk safety installations has impact to the performance of rupture disk, may cause rupture disk can not reliably working time, answer set temperature screening arrangement.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of rupture disk special-purpose metal high-temperature shielding device.
Rupture disk special-purpose metal high-temperature shielding device of the present utility model, it comprises upper flange, lower flange, bolt, supporting frame, thermal baffle, rupture disk, clamp holder, between upper flange and lower flange, be bolted to connection, between upper flange and lower flange, be provided with supporting frame, the upper and lower surface of supporting frame is separately installed with thermal baffle, the spot welding of rupture disk assembling rear perimeter edge, is arranged in clamp holder.
As preferably, during joint strip spot welding on described thermal baffle, according to outer ring, just paste, inner ring is counter pastes operation.
The beneficial effects of the utility model: its reasonable in design, simple to operate, it is convenient to install, there is high temperature resistant, corrosion resistance and good effect of heat insulation, non-environmental-pollution after explosion, safe and reliable, can effectively guarantee bursting pressure, meet people's user demand.
Accompanying drawing explanation
For ease of explanation, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of thermal baffle in the utility model.
1-upper flange; 2-lower flange; 3-bolt; 4-supporting frame; 5-thermal baffle; 6-rupture disk; 7-clamp holder.
Embodiment
As Fig. 1, shown in Fig. 2, this embodiment is by the following technical solutions: it comprises upper flange 1, lower flange 2, bolt 3, supporting frame 4, thermal baffle 5, rupture disk 6, clamp holder 7, between upper flange 1 and lower flange 2, by bolt 3, be fixedly connected with, between upper flange 1 and lower flange 2, be provided with supporting frame 4, the upper and lower surface of supporting frame 4 is separately installed with thermal baffle 5, and rupture disk 6 assembling rear perimeter edge spot welding, are arranged in clamp holder 7.
Wherein, described; During joint strip spot welding on described thermal baffle 5, according to outer ring, just paste, inner ring is counter pastes operation.
The working principle of this embodiment: heat is delivered in material exchange heat and shows as three kinds of modes, is respectively hot conduction, thermoconvection and thermal radiation, and thermal-protective material can block hot-fluid transmission; When the medium temperature in container is very high, the reflectivity itself having by thermal baffle 5 reflects away most of heat, and the hole on thermal baffle 5 forms thermoconvection simultaneously, takes away a part of heat, thereby plays the effect that retardance hot-fluid is propagated.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
