Abstract
The invention discloses a safe pressure relief protection device for pipelines of high-pipeline-pressure equipment such as blast furnaces and smelting furnaces. A pipeline pressure relief anti-explosion valve with a simple structure is provided. The valve comprises a pressure relief opening in a pipeline body. An anti-explosion cover plate is installed in the pressure relief opening, and a movable gap is reserved between the periphery of the anti-explosion cover plate and the inner cavity wall of the pressure relief opening. A rotary shaft is installed in the center of the anti-explosion cover plate. A pressure spring is installed above the upturned side of the anti-explosion cover plate, and meanwhile a supporting boss is arranged below the upturned side of the anti-explosion cover plate on the inner cavity wall of the pressure relief opening. The smelting furnace pipeline anti-explosion valve is simple in structure, safe, reliable and low in investment and maintenance cost.
Description
Technical field
The present invention relates to a kind of safety relief protection dress of pipeline for the larger equipment of the pipeline pressures such as blast furnace, smelting furnace
Put.
Background technology
Using in the smelting equipment production processes such as steel-making, ironmaking, coke oven, substantial amounts of flue dust and poisonous and harmful gas will be produced
Body, and pressure will be produced in airtight smelting body of heater and pipeline, if other pressure exceed safety value it may occur that exploding
Or equipment damage, or even cause personal injury, reduce pressure in body of heater therefore when body of heater pressure exceedes safety limit, prevent from exploding
It is the problem that must solve.
As the patent No. 200620078688.6 discloses a kind of " gas-closed safety explosion-proof valve ", it adopts installation on pipeline
By the venting of dust explosion valve gap of spring compression, after pipeline pressure exceedes safe design value, valve gap is promoted by air pressure and opens, and realizes pressure release.
But this apparatus structure is complicated, it is unfavorable for installing and safeguards, particularly when increasing air pressure moment, very big to the impulsive force of spring,
Easily cause the damage of device.
Content of the invention
The technical problem to be solved is to provide a kind of structure simple pipeline pressure release explosion-proof valve.
The present invention solves its technical problem adopted smelting furnace pipeline explosion-proof valve, including the pressure relief opening on pipeline body, lets out
In pressure mouth, explosion-proof covering board is installed, between the neighboring of explosion-proof covering board and the internal chamber wall of pressure relief opening, leaves free gap；Explosion-proof
Cover plate central is provided with rotary shaft；Explosion-proof covering board turns over holddown spring is installed above side, simultaneously in the inner chamber of pressure relief opening
Turn over side-lower on the explosion-proof covering board of wall and be provided with support rim.
On pipeline body and explosion-proof covering board, setting diaphragm seal covers on free gap.
Sealing gasket is laid in free gap.
Above-mentioned diaphragm seal and sealing gasket adopt flexible material to make.
In the bottom of holddown spring, pinch roller is installed.
The fixing end of holddown spring is provided with hinges.
Using the smelting furnace pipeline explosion-proof valve of the present invention, structure is simple, safe and reliable, and investment and maintenance cost are low.

Specific embodiment
Below in conjunction with the accompanying drawings the concrete structure and work process of the smelting furnace pipeline explosion-proof valve of the present invention is carried out specifically
Bright.
It is provided with pressure relief opening 10 on pipeline body 1 as shown in Figure 1, Figure 2 and Figure 3, be provided with explosion-proof in pressure relief opening 10
Cover plate 2, leaves free gap 11 between the internal chamber wall of the neighboring of explosion-proof covering board 2 and pressure relief opening 10, be easy to explosion-proof covering board 2 and turning over
Will not interfere with the internal chamber wall of pressure relief opening 10 when turning.At explosion-proof covering board 2 center, rotary shaft 3 is installed, when in pipeline body 1
Pressure when exceeding safety value, explosion-proof covering board 2 rotates around rotary shaft 3, that is, explosion-proof covering board 2 on turn over side 21 and be flipped up, separately
Side downwardly turns over, and produces spacing and opens, realize in pipeline between the internal chamber wall of the neighboring of explosion-proof covering board 2 and pressure relief opening 10
The effect of pressure release.
When explosion-proof covering board 2 normally closes pressure relief opening 10, explosion-proof covering board 2 turns over above side 21 and holddown spring is installed
4, simultaneously the internal chamber wall of pressure relief opening 10 explosion-proof covering board 2 on turn over and be provided with support rim 6 below side 21, by holddown spring
4 thrust and the support of support rim 6, make explosion-proof covering board 2 horizontal positioned, reduce free gap 11, prevent and reduce pipeline
In gas leakage.
In order to preferably reduce gas leakage, as shown in figure 1, diaphragm seal 8 is arranged on pipeline body 1 and explosion-proof covering board 2
Cover on free gap 11, or as shown in Fig. 2 lay sealing gasket 9 in free gap 11.Above-mentioned diaphragm seal 8 and sealing
Pad 9 is made using such as the flexible materials such as asbestos, so will not block explosion-proof covering board 2 when explosion-proof covering board 2 overturns.
When explosion-proof covering board 2 overturns, between holddown spring 4 and explosion-proof covering board 2, sliding will occur, in order to reduce each other
Frictional resistance, in the bottom of holddown spring 4, rotary pinch roller 7 is installed for this.Separately because other in pipeline exceed
After safety value.Easily cause the pressure release of moment, the upset of explosion-proof covering board 2 occurs quickly and upset amount is very big, produces to holddown spring 4
The radial impact of raw moment, thus damaging the fixed structure of holddown spring, so the fixing end in holddown spring 4 is provided with activity
Hinge 5, the infringement of buffering radial impact force.
Although describing the present invention in detail above in association with drawings and Examples, those of ordinary skill in the art should be clear
Chu, in the case of without departing from claim spirit and scope, can carry out various modifications to above-described embodiment, all in this
Within bright protection domain.
