Description
Technical Field
The utility model relates to a ventilation valve technical field especially relates to an explosion-proof type fire prevention valve.
Background
At present, traditional explosion-proof type fire prevention valve adopts steel framework and aluminium system blade structure, because of aluminium system product when sealing off, it touches the steel framework and can not produce the spark, so it has explosion-proof effect.
Although the product has an explosion-proof effect, the aluminum blade begins to soften or even melt when the environmental temperature exceeds 400-660 ℃, and the requirement of fire resistance and temperature resistance of more than 1000 ℃ cannot be met. Some manufacturers adopt the structures of steel frame bodies and non-metal refractory blades, but have the problems of difficult processing, heavy products and the like, and are not the mainstream technology.
In view of the technical disadvantages of the above products, as a person skilled in the art, it is very necessary to design an improved product which can realize an explosion-proof function and ensure structural stability at high temperature.
Disclosure of Invention
In order to solve the deficiencies in the prior art, an object of the utility model is to provide an explosion-proof type fire prevention valve of novel structure, it can combine fire prevention, high temperature prevention and explosion-proof function stability to same product.
The utility model provides a technical scheme that its technical problem adopted is:
an explosion-proof type fire-proof valve comprises a frame body, an explosion-proof blade, a stainless steel elastic sheet, a connecting rod assembly and an actuating mechanism; a baffle plate and a shaft sleeve frame are arranged in the frame body; the shaft sleeve frame is distributed with shaft sleeves, and the explosion-proof blades are fixed through the shaft sleeves; the explosion-proof type blade is formed by connecting two layers of plates, wherein one layer of plate is made of steel material, and the other layer of plate is made of aluminum material; the length and width of the aluminum blade are slightly larger than those of the steel blade, so that only the aluminum blade is in contact with the frame body when the valve is opened and closed.
The stainless steel elastic sheet is arranged on the shaft sleeve frame, the length of the stainless steel elastic sheet is equal to that of the copper sleeve frame, two ends of the stainless steel elastic sheet are abutted to the frame body, and the gap between the frame body and the blade is reduced through the elastic compensation performance of the elastic sheet, so that the sealing effect is achieved.
The both ends of explosion-proof type blade be provided with the blade axle, the blade axle passes the axle sleeve and makes the blade assembly inside the framework, and can rotate in a flexible way, works as when blade quantity is greater than 1, link together a plurality of blades through link assembly and realize the synchronous rotation of blade.
The actuating mechanism is an explosion-proof actuating mechanism and can control the opening and closing of the fire-proof valve.
The utility model has the advantages that: the frame body and the blades are reasonable in structural design, the double-layer blades made of different materials are utilized, the high-temperature-resistant requirement of the fire damper is met, meanwhile, the problem that sparks are possibly generated during the action of the blades to cause explosion is solved, and the functions of an explosion-proof valve and a fire damper are achieved.

FIG. 1 is a schematic perspective view of the present invention;
FIG. 2 is a schematic perspective view II of the present invention;
FIG. 3 is a schematic view of the structure of the present invention;
FIG. 4 is a perspective view of an explosion-proof vane;
in the figure: the anti-explosion type blade comprises a frame body 1, a copper sleeve frame 1-1, a shaft sleeve 1-2, a baffle 1-3, a stainless steel elastic sheet 1-4, an anti-explosion type blade 2-1, a steel blade, an aluminum blade 2-2, a blade shaft 2-3, a connecting rod assembly 3 and an anti-explosion type actuating mechanism 4.
Detailed Description
The following description is provided for illustrative purposes and to provide further explanation of the invention as claimed.
As shown in fig. 1, 2 and 3: the embodiment discloses an explosion-proof type fire prevention valve, including framework 1, blade explosion-proof type 2, link assembly 3, explosion-proof type actuating mechanism 4, valve body 1 comprises two pairs of frame parts that the opposite side is the same, the axle sleeve frame adopts copper sheathing frame 1-1, its cross-section is "nearly" style of calligraphy structure that sets up towards framework 1 inner wall, stainless steel shell fragment 1-4 is for placing on copper sheathing frame 1-1, length and copper sheathing frame 1-1 are equal, both ends offset with valve body 1, through the elasticity performance of shell fragment, make valve body and blade clearance even.
The explosion-proof type blade 2 comprises a steel blade 2-1, an aluminum blade 2-2 and a blade shaft 2-3 clamped between the two blades, wherein the blade shaft 2-3 of the explosion-proof type blade 2 penetrates through the shaft sleeve 1-1 to be arranged inside the valve frame and can flexibly rotate by taking the blade shaft 2-3 as an axis. The length difference of the aluminum blade is about 2mm compared with the length difference of the steel blade, so that the explosion-proof blade is ensured to be only in contact with the frame body 1 when the aluminum blade rotates, and the explosion of combustible gas and dust in the environment caused by sparks is avoided.
The explosion-proof type actuating mechanism 4 is arranged outside the frame body 1, drives the blade shafts 2-3 to drive the explosion-proof type blades 2 to swing, and the explosion-proof type blades 2 are connected into a whole through the connecting rod assembly 3 to realize linkage.
The above only is the preferred embodiment of the present invention, as long as the preferred embodiment is realized by basically the same means, the objective technical solution of the present invention all belongs to the protection scope of the present invention.
