Abstract
The utility model discloses a high-temperature flue shutter valve, consisting of a valve body, a valve plate, an electric lifting device and a valve plate portal frame. The valve body is connected with a gas flue. The valve plate is inserted into the inside of the valve body. The valve plate portal frame is on the valve body. The electric lifting device is arranged on the valve plate portal frame, and is connected with the valve plate through a steel cable. The utility model is provided with some advantages of simple structure, convenient to maintain and can reliably cutting down flue gas with high temperature of pipeline to realize automatic control. The refractory temperature of the utility model is as high as 1000-1200 DEG C. And the high-temperature flue shutter valve largely improves the efficiency of production run, and decreases equipment failure rate.
Description
Technical field:
The utility model relates to high-temperature flue gas pipeline shut-off means in a kind of thermal power and the stove engineering, especially can cut off temperature up to more than 1000 ℃ and the big tunnel gas of flow.
Technical background:
At present, in high-temperature flue gas pipework, majority does not adopt shut-off means, or adopts the lower cast iron of common heatproof to make cut-off valve.Utilize manifold road system for fume afterheat, high-temperature flue gas pipeline especially, the pipeline that there is no need cuts off.This has adverse effect to production run.Even and adopted common cut-off valve because working time is short, heatproof is low, change maintenance rate height, seriously restricted the ordinary production operation, reduced operational efficiency.
Summary of the invention:
The purpose of this utility model is: a kind of high-temperature flue gas pipeline shut-off means is provided, and this device heatproof degree is up to 1000～1200 ℃, and more than pipe diameter DN1000～DN3000, rupturing operation is convenient reliable, easily realizes control automatically.
The utility model is to constitute like this: it is by valve body (1), valve plate (2), electric lifting device (3), valve plate door frame (4) is formed, valve body (1) connects flue (5), and valve plate (2) inserts in the valve body (1), and valve plate door frame (4) is on the valve body (1), electric lifting device (3) is contained on the valve plate door frame (4), and connects valve plate (2) by wire rope (6).Valve plate (2) is made of valve plate muscle net (7) and castable refractory (8).
The utility model compared with prior art has simple in structurely, easy to maintenance, can cut off the pipeline high-temperature flue gas reliably, realizes advantages such as control automatically.Its high temperature resistant degree is up to 1000～1200 ℃, and improved production run efficient greatly, reduces equipment failure rate.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the schematic representation of valve plate (2).
Embodiment:
Embodiment of the present utility model: valve body (1) connects flue gas turnover flue (5), and valve plate (2) is moved up and down by valve plate door frame (4), wire rope (6) and electric lifting device (3) in valve body (1) U-shaped guiding groove and opens or closes flue (5).
Valve plate (2) adopts high temperature resistant castable refractory (8) and prefabricated the forming of valve plate muscle net (7), top installing valve plate hanger (9).
Claims (2)
1, a kind of high-temperature flue push-pull valve, it is by valve body (1), valve plate (2), electric lifting device (3), valve plate door frame (4) is formed, and valve body (1) connects flue (5), valve plate (2) inserts in the valve body (1), valve plate door frame (4) is on the valve body (1), and electric lifting device (3) is contained on the valve plate door frame (4), and connects valve plate (2) by wire rope (6).
2, high-temperature flue push-pull valve according to claim 1 is characterized in that: valve plate (2) is made of valve plate muscle net (7) and castable refractory (8).
