Abstract

A boiler which can not explode when it is boiling dry features that the fusible valve is installed to the cylindrical main body or closure head and over-pressure and over-heat can fuse it to release the pressure. If said fusible valve is installed to the position where is near the fire or has the most heat absorptivity and when the boiler is boiling dry, the temp is raised to fuse it, so preventing explosion of boiler.

Description

The boiler of explosionproof as being dried

Technical field

The present invention relates to the secure context of steam boiler.

Technical background

The safety measure of prior art all is effectively, but boiler is interior not to be stopped as yet above the anhydrous blast that causes in setting pressure or the pot because maloperation causes.

Summary of the invention

Technical problem to be solved by this invention is, provide that a kind of usefulness is overheated promptly decreases the boiler that part guarantees the explosionproof as being dried when anhydrous in the boiler, concrete method is at drum, suitable place such as manhole or end socket is provided with meltable valve, pressure release when surpassing safe pressure owing to supercharging heats the fusible material fusing, if this valve gear is socketed burning things which may cause a fire disaster or the highest place of heat absorption rate most at the heat absorption comb of boiler or inner bag, when boiling dry in the boiler, though pressure at this moment is normal, but pressure release because so anhydrous heat absorption comb or inner bag intensification fusible material melt, because this valve is to be again side towards the fire near burning things which may cause a fire disaster, so the saving oneself property of gas of releasing in the time of pressure release fire in the stove is blown out to guarantee the safety when boiler boils dry, the valve of this position also has the effect of other positions.

When the pressure of boiler is raised to the maximum of safe pressure owing to increasing of pressure and temperature meltable valve fusing pressure release simultaneously the heat resisting temperature that fire is extinguished fusible material of saving oneself property be to decide with the safe pressure of this boiler, boiler that safe pressure is 160KPa for example, at this moment temperature be 200 ℃ can the fusing point of fusible material be located at 200 the degree get final product, the quantity of safety valve requires to be as the criterion with the pressure release that its all aperture additions meet this boiler, its distribution situation one is to satisfy that above what spoken of is that satisfy can the most effective requirement that fire is blown out in the shortest time near burning things which may cause a fire disaster or the highest place two of heat absorption rate, can establish some the place or the local of coal combustion just of hyperactivity of fire more.

Description of drawings

Fig. 1 is the cutaway view of fixing meltable valve;

Fig. 2 is the cutaway view of meltable valve alive;

The specific embodiment

As shown in the figure, Fig. 1 is the section relation that this figure of cutaway view of fixing meltable valve has illustrated fixing meltable valve 1 and boiler structure 2, and this valve is fit to be contained in removable position for example on end socket, manhole or the hand hole, also can be contained in other positions.Standing valve itself is exactly a fusible material.Method with self riveting is fixed.

Fig. 2 be live meltable valve cutaway view it the section relation of live meltable valve 3 and boiler structure 2 has been described, provided fusible material 4 simultaneously, the situation of nut 5 screws off nut, just valve can be taken out, the hole of meltable valve 3 and boiler structure 2 all is oval, the hole hand hole of down making things difficult for others is the same, and this valve is suitable for use on drum comb or the inner bag so that dismounting.

When the pressure of boiler is raised to the maximum of safe pressure, owing to increasing of pressure and temperature meltable valve fusing pressure release simultaneously the heat resisting temperature that fire is extinguished fusible material of saving oneself property be to decide with the safe pressure of this boiler, boiler that safe pressure is 160KPa for example, at this moment temperature be 200 ℃ can the fusing point of fusible material be located at 200 the degree get final product, the quantity of safety valve requires to be as the criterion with the pressure release that its all aperture additions meet this boiler, its distribution situation one is to satisfy that above what spoken of is that satisfy can the most effective requirement that fire is blown out in the shortest time near burning things which may cause a fire disaster or the highest place two of heat absorption rate, can establish some the place or the local of coal combustion just of hyperactivity of fire more.Safety when above valve can guarantee to boil dry pot.

Claims

1. the boiler of an explosionproof as being dried is characterized in that: be prefabricated into the serratd edge part earlier again with the way of sticking, weldering, riveting or bolt, the serratd edge part be fixed on the bottom of original serratd edge.
