Description
Technical Field
The utility model relates to a fire-fighting equipment, especially an explosion-proof type low multiple air foam generator.
Background
The low multiple foam generator is fixedly installed on an oil tank, sprays foam on liquid to the surface of combustible liquid, quickly covers the whole combustion surface, extinguishes fire and effectively prevents the spread of fire. It is mainly suitable for the production, storage, transportation and use places of inflammable and combustible liquids. Is especially suitable for fighting storage tank fire and large-area flowing fire. Traditional low multiple foam generator provides the foam mixed liquid that has pressure by foam mixing arrangement, and foam mixed liquid just can enter into the storage tank after breaking sealed glass under the effect of pressure and put out a fire after entering foam generator through fire control pipeline. Since glass is fragile, sealing glass is easily crushed when negative pressure is generated in the tank, so that gas in the tank leaks, and not only air pollution but also more serious consequences can be caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the technical problem and providing an explosion-proof type low multiple air foam generator, solve sealed glass and bear the broken and jar interior liquid reflux's that leads to problem of limit.
The utility model provides a its technical problem, the technical scheme of adoption is:
an explosion-proof low-multiple air foam generator comprises a foaming body and a step connecting pipe, wherein the upper end of the step connecting pipe is arranged in the foaming body, an upper flange is fixedly connected to the outer circumferential surface of the upper end of the step connecting pipe, a convex shoulder structure is arranged on the inner circumferential surface of the upper flange, a sealing washer, an organic glass plate and a clamp spring are sequentially installed on the upper ring surface of the convex shoulder structure, and the clamp spring is embedded in a groove in the inner circumferential surface of the upper flange.
Adopt above-mentioned technical scheme the utility model discloses compare with prior art, beneficial effect is:
the sealing structure is simple, the number of parts is small, and the realization is easy; can be used repeatedly for a long time without replacement, avoids the problem of liquid backflow in the tank caused by the negative pressure in the tank exceeding the glass bearing limit, and really achieves no worry about the situation.
Further the utility model discloses an optimization scheme is:
the cross section of the clamp spring is circular, and 1/3 of the cross section of the clamp spring is embedded into the groove.
The sealing ring is made of glass.

Detailed Description
The present invention will be further described in detail with reference to the accompanying drawings and examples.
Referring to fig. 1 and 2, the embodiment is an explosion-proof low-expansion air foam generator, which is composed of a step connection pipe 3, a foam body 4, a sealing washer 5, an organic glass plate 6, a snap spring 7, an upper flange 8 and the like. The foaming body 4 is cylindrical, the axis of the foaming body is vertically arranged, the bottom of the foaming body is obliquely arranged, the upper end of the foaming body is provided with a foaming body flange 9, and a foaming body upper cover 10 is connected with the foaming body flange 9. The outlet flange 11 is mounted on the bottom of the side of the foam body 4.
The upper end of the ladder connecting pipe 3 penetrates through the bottom of the foaming body 4, the upper end of the ladder connecting pipe 3 is positioned in the middle of the cavity of the foaming body 4, and the axis of the ladder connecting pipe 3 is superposed with the axis of the foaming body 4. The outer periphery of the upper end of the stepped connecting pipe 3 is welded with the upper flange 8, the inner circumferential surface of the upper flange 8 is provided with a radial convex shoulder structure, the lower circumferential surface of the convex shoulder structure is positioned on the upper end surface of the stepped connecting pipe 3, the upper ring surface of the convex shoulder structure is sequentially provided with a sealing washer 5, an organic glass plate 6 and a clamp spring 7, the sealing washer 5 is made of glass, the organic glass plate 6 is circular (shown in figures 4 and 5), the upper end opening of the stepped connecting pipe 3 is sealed by the organic glass plate 6, the cross section of the clamp spring 7 is circular (shown in figure 3), the clamp spring 7 is an inner clamp spring, 1/3 of the clamp spring 7 is embedded in a groove in the inner circumferential surface of the upper flange 8, and the clamp spring 7 is used for limiting the organic glass plate 6.
When the foam generator is in a non-working state, the sealed organic glass plate 6 is pressed on the sealing washer 5, and the elastic clamp spring 7 is clamped in the groove of the upper flange 8 at the upper end of the stepped connecting pipe 3 to play a role in compressing and fixing the sealed organic glass plate 6; when the foam generator is in a working state, when pressure foam liquid is flushed to the organic sealing glass plate 6 in the foam generator, the organic glass plate 6 is pushed under the action of the pressure, the organic glass plate 6 pushes the elastic clamp spring 7, the clamp spring 7 is separated from the groove and falls out of the stepped connecting pipe 3 and then falls into a cavity of the foaming body 4 together with the organic glass plate 6, and the foam liquid enters the tank body to extinguish fire.
The utility model discloses can also process the up end of ladder connecting pipe 3, go up the upper surface of flange 8 and leave seal ring 5, organic glass board 6 and jump ring 7's mounting dimension with the up end of ladder connecting pipe 3.
The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all structural equivalents made by using the contents of the specification and drawings are included in the scope of the present invention.
