Advanced flow control valve could effectively ensure that indoor rate of ventilation requires and pressure control requires, and venturi valve is one
The advanced flow control valve of kind.The venturi valve is applied in all kinds of chemical enterprises, inspection and quarantine place, due to external condition
Particularity, it is therefore desirable to prevent danger, the venturi valves such as extraneous generation fire, explosion from needing when unexpected situation occurs, answering
Work as emergent stopping, and protect internal structure, prevents equipment damage or other secondary accidents.
Utility model content
In order to solve the above technical problems, the utility model proposes a kind of explosion-protection equipment of venturi valve, the venturi
Valve includes valve body and the adjusting rod for adjusting air quantity, and the adjusting rod connects regulating device, and the explosion-protection equipment includes babinet,
Guide rail is set in the babinet, slide plate is set on the guide rail, regulating device, the slide plate end connection are set on the slide plate
Spring, the spring are connect with the babinet, and fire-fighting glass marble is arranged in the spring inner.
Preferably, the regulating device is set as cylinder, and the cylinder is connect with air source.
Preferably, venthole is set on the babinet, and the slide plate end set baffle, the baffle can be with the outlet
Hole offsets.
Preferably, the high organic solution of setting coefficient of thermal expansion inside the fire-fighting glass marble.
Preferably, the babinet uses heat proof material.
The utility model has following advantageous effect：Effective blast resistance construction can promptly be closed inside when surprisingly occurring
Structure, and the urgent closing of venturi valve in addition, when external temperature is excessively high, can be led to heated inside anti-explosion box body, air
When expansion, internal high pressure gas is discharged in the opening gap that babinet can be spontaneous.

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
As shown in Figure 1-Figure 3, the utility model proposes a kind of explosion-protection equipment of venturi valve, venturi valve includes valve body
1 and the adjusting rod for adjusting air quantity, adjusting rod connects regulating device 42, and explosion-protection equipment includes babinet 3, in babinet 3 setting lead
Slide plate 52 is arranged on guide rail 53 for rail 53, is arranged regulating device 42 on slide plate 52,52 end connecting spring 42 of slide plate, spring 42 with
Babinet 3 connects, 42 inside setting fire-fighting glass marble 41 of spring.
Specifically, by being arranged regulating device 42 on carriage 5, carriage 5 is connected to spring 42 and babinet
3, the high organic solution of 41 inside setting coefficient of thermal expansion of fire-fighting glass marble leads to internal liquid when fire-fighting glass marble 41 is heated
Body expands, and fire-fighting glass marble 41 is broken, to which no longer support spring 42, spring 42 pull carriage 5 to be moved on guide rail 53,
The mobile drive regulating device 42 of carriage 5 is by adjusting rod dieback, to close venturi valve.
Regulating device 42 is set as cylinder, and cylinder is connect with air source；
Inside is according to electronic regulating device 42, due to electromagnetic relationship, generates ionization with external chemical compound gas, has
Cause extraneous explosion possibility, therefore using without power supply cylinder it is safer as power source, the output end of cylinder and
Adjusting rod offsets.
Venthole 31,52 end set baffle 51 of slide plate are set on babinet 3, and baffle 51 can offset with venthole 31；
As shown in figure 4, after fire-fighting glass marble 41 is broken, spring 42 is slided baffle 51 is dragged to babinet 3, on babinet 3
The venthole 31 of setting is covered by baffle 51.When inside, when gases are heated, they expand, when pressure arrives greatly certain value, pushes 51 grams of baffle
The elastic force for taking spring 42 moves out, the high pressure gas inside the interior discharge of venthole 31, after internal pressure reduction is discharged in gas,
Baffle 51 is continued to block venthole 31 by the pulling force of spring 42.
Babinet 3 uses heat proof material.In addition, the material hardness and intensity of babinet 3 be also required to it is higher, for example, by using ceramic material
Material or alloy material make babinet 3 be heated and made to play the demand for protecting internal structure by impact.
A variety of modifications of embodiment will be apparent to those skilled in the art, determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The widest range consistent with features of novelty.
