Description
Technical field
The utility model relates to fire resisting damper fields, especially relate to a kind of for there may be explosive gas mixtures
Anti-explosion fire-resisting valve.
Background technique
The fire resisting damper applied in current fire-fighting ventilating system, when encountering fire, in predetermined temperature and in the time, generally
It is able to achieve and is automatically closed, play the role of isolation fire source, block flue gas, but existing common fire resisting damper only leans on valve block and valve
Sealing between piece, valve block and valve body, sealing performance is generally bad, simultaneously because valve block is made of ordinary carbon steel, when valve event,
Adjacent steel blade collision may generate spark, thus the explosive gas mixture that ignites.
Utility model content
To overcome drawbacks described above, the utility model is intended to provide a kind of better tightness, while having the anti-of explosion prevention function
Fiery valve.
To achieve the above object, the technical scheme adopted by the utility model to solve the technical problem is as follows: it is a kind of explosion-proof anti-
Fiery valve is fixed with a meltable bar and one on outline border including a monoblock type outline border and several valve blocks being located in it
A explosion-proof executing agency, the valve block include a blade and a sharf, the end of the sharf and a spring phase
It connects, is respectively equipped with a block baffle on the outline border two frames parallel with valve block, two ends of the blade are respectively equipped with
The reinforcing rib of one semicircle is respectively equipped with a reinforced sheet at the reinforcing rib, also is provided with one and blade on the reinforced sheet
The contrary reinforcing rib of upper reinforcing rib, two ends of the blade are respectively equipped with sealing reed, and the sharf both ends are set
There is copper bush, copper shaft set is supported in blade rack, and spring housing is added between the valve block and blade rack.
The outline border, valve block, blade, reinforced sheet, sharf, blade rack, baffle and spring are by ordinary carbon steel material system
At the spring housing and sealing reed material are copper alloy.
Make blade rack by adding spring housing and sealing reed using a kind of anti-dryness-fire valve of the utility model
Between valve block, there is better sealing between valve block and valve block.Since steel material and copper alloy will not be produced in collision
It lights a fire flower, as long as fire resisting damper everything contact position is the collision of steel and copper, explosion-proof effect can be generated.It is practical new using this
A kind of anti-dryness-fire valve of type, valve block and valve block contact position sealing reed material are copper alloy, the upper and lower end face of valve block and blade rack
Contact position spring shield shell material matter is copper alloy, and sharf and blade rack contact position are copper bush, while having installed explosion-proof execution additional
Mechanism makes entire fire resisting damper be provided with explosion prevention function.It is since entire fire resisting damper only has spring housing, sealing reed, copper bush
Copper alloy, it is other to be all made of ordinary carbon steel, cost is greatly saved.
Detailed description of the invention

Fig. 2 is the A-A sectional view of Fig. 1；
Fig. 3 is the valve structure schematic diagram of the utility model；
Fig. 4 is the B-B sectional view of Fig. 1.
In figure: 1- outline border, 2- blade rack, 3- spring housing, 4- baffle, 5- valve block, the explosion-proof executing agency of 6-, 7- are meltable
Bar, 8- spring, 9- reinforced sheet, 10- seal reed, 11- sharf, 12- copper bush, 13- blade, 20- reinforcing rib.
Specific embodiment
As Figure 1-Figure 4, it the utility model discloses a kind of anti-explosion fire-resisting valve, including a monoblock type outline border 1 and sets
Several valve blocks 5 in it are fixed with a meltable bar 7 and an explosion-proof executing agency 6, the valve block 5 on the outline border 1
Including a blade 13 and a sharf 11, the end of the sharf 11 is connected with a spring 8, the outline border 1 with
A block baffle 4 is respectively equipped on two parallel frames of valve block 5, two ends of the blade 13 are respectively equipped with adding for a semicircle
Strengthening tendons 20 are respectively equipped with a reinforced sheet 9 at the reinforcing rib 20, also be provided on the reinforced sheet 9 one on blade 13 plus
The contrary reinforcing rib 20 of strengthening tendons 20, two ends of the blade 13 are respectively equipped with sealing reed 10, the sharf 11
Both ends are equipped with copper bush 12, and copper shaft set 12 is supported in blade rack 2, add bullet between the valve block 5 and blade rack 2
Spring housing 3.
The outline border 1, valve block 5, blade 13, reinforced sheet 9, sharf 11, blade rack 2, baffle 4 and spring 8 are by common
Carbon steel material is made, and the spring housing 3 and sealing 10 material of reed are copper alloy.
Make blade branch by adding spring housing 3 and sealing reed 10 using a kind of anti-dryness-fire valve of the utility model
Between frame 2 and valve block 5, there is better sealing between adjacent two valve blocks 5.Since steel material and copper alloy are in collision
Spark will not be generated, as long as fire resisting damper everything contact position is the collision of steel and copper, explosion-proof effect can be generated.Pass through valve block
5 with 5 contact position of valve block sealing 10 material of reed be copper alloy, the upper and lower end face of valve block 5 and 2 contact position spring housing 3 of blade rack
Material is copper alloy, and sharf 11 and 2 contact position of blade rack are copper bush 12, while having installed explosion-proof executing agency 6 additional, is made whole
A fire resisting damper is provided with explosion prevention function.Since entire fire resisting damper only has spring housing 3, sealing reed 10, copper bush 12 for copper conjunction
Gold, it is other to be all made of ordinary carbon steel, cost is greatly saved.
