Abstract
A kind of inerting system belongs to coal storage silo inertia protection device technical field, technical problem to be solved is to provide a kind of scavenging air valve that can control scavenging period and ventilation safe, used technical scheme from motion tracking scavenging air valve：A kind of inerting system is from motion tracking scavenging air valve, including valve body, bonnet, valve element, spacer flanger and companion flange, the companion flange is arranged on body top, and the spacer flanger is arranged on body base, the bonnet is arranged on valve inner, while is provided with valve element again inside bonnet；The valve body is connected by spacer flanger with the inlet end of inert gas appendix, and valve body is connected by companion flange with the outlet side of inert gas appendix, and the utility model is taken a breath applied to coal storage silo.
Description
Technical field
A kind of inerting system belongs to coal storage silo inertia protection device technical field from motion tracking scavenging air valve.
Background technology
Power plant and chemical plant coal storage silo are typically all up to ten thousand tons of coal storage, do not have to for a long time in the silo when coal or
Product coal, temperature in silo will be caused to raise, cause silo to catch fire or explode, so needing to fill to coal storage silo by appendix
Inert gas is protected, and ventilation displaces material above imflammable gas concentration and combustion source in coal store.Work as system detectio
When producing advanced alarm signal to coal storage silo, system produces from trend successively changes from low to high in the coal storage silo of alarm signal
Gas, hazardous gas is discharged to high level from bottom, is finally discharged at the top of coal store, reach to be changed in coal store with inert gas and endanger
The purpose of dangerous gas.Existing this scavenging way scavenging period is not safe enough, scavenging period can not be controlled.
Utility model content
Technical problem to be solved in the utility model, which is to provide, a kind of can control changing for scavenging period and ventilation safe
Air valve.
In order to solve the above technical problems, technical scheme used by the utility model：A kind of inerting system changes from motion tracking
Air valve, including valve body, bonnet, valve element, spacer flanger and companion flange, the companion flange is arranged on body top, in described
Between flange be arranged on body base, the bonnet is arranged on valve inner, while is provided with valve element again inside bonnet；
The valve body is connected by spacer flanger with the inlet end of inert gas appendix, valve body by companion flange with it is lazy
Property gas appendix outlet side connection.
The companion flange and body top bolt connection, the spacer flanger and body base bolt connection；
The inlet end of the companion flange and inert gas appendix is welded and fixed, and the companion flange and inert gas are defeated
The outlet side of tracheae is welded and fixed.
Compared to the prior art the utility model has the advantages that：By the way that the utility model is arranged on into coal-storage cylinder
In the middle part of the appendix in storehouse, coal storage silo is divided into two ventilation layers up and down along the utility model, the Opening pressure of valve is valve element
Gravity, after bottom inert gas plenum pressure reaches VOP, valve element is jacked up upwards, and valve automatically opens up,
Gas flows out from the air outlet of bonnet, then flows to the gas outlet of valve body, continues, toward high-rise inflation, to realize valve silo inertia gas
From bottom to top from motion tracking ventilatory, when inlet pressure falls below valve element gravity, valve element automatically resets, valve
Door close, realize valve automatically open up and open function.The utility model is simple in construction, easy to use, automaticity
Height, security are good.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
In figure, 1 is valve body, and 2 be bonnet, and 3 be valve element, and 4 be spacer flanger, and 5 be companion flange.
Embodiment
As shown in figure 1, a kind of inerting system is from motion tracking scavenging air valve, including valve body 1, bonnet 2, valve element 3, spacer flanger 4
With companion flange 5, the companion flange 5 is arranged on the top of valve body 1, and the spacer flanger 4 is arranged on the bottom of valve body 1, the valve
Lid 2 is arranged on inside valve body 1, while is provided with valve element 3 again in the inside of bonnet 2；
The valve body 1 is connected by spacer flanger 4 with the inlet end of inert gas appendix, and valve body 1 passes through companion flange 5
Connected with the outlet side of inert gas appendix.
The companion flange 5 is connected with the top bolt of valve body 1, and the spacer flanger 4 is connected with the bottom bolts of valve body 1；
The inlet end of the companion flange 4 and inert gas appendix is welded and fixed, the companion flange 5 and inert gas
The outlet side of appendix is welded and fixed.
Above-described embodiment is the explanation to the utility model structure and unrestricted, is not departing from the utility model principle premise
Lower made deformation is also within the scope of protection of the utility model.
