Abstract
The utility model relates to a high temperature biomass gas block valve. The high temperature biomass gas block valve comprises a valve body and a valve plate, wherein a gas inlet and a gas outlet are formed on the valve body; the valve plate is arranged within the valve body and matches with one of the gas inlet or the gas outlet; the valve plate is hinged with the valve body by a valve shaft; and the valve shaft is arranged at the edge of the valve plate. According to the utility model, because the valve shaft is arranged at the edge of the valve plate, namely a low temperature area, the valve shaft is effectively prevented from being positioned in a high temperature area for a long time so that the valve shaft cannot be deformed and good sealing effect is obtained; because an elastic sealing ring is arranged at the sealing part of the valve plate, soft sealing is achieved so that advantages of good sealing effect, high temperature resistance, corrosion resistance and stability are obtained; and because the valve body is of cube shape and opening can be formed at multiple surfaces of the valve body to connect different pipelines, an effect of changing the gas conveying direction in the gas conveying process is conveniently and rapidly achieved.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of high temperature biogas block valve.
Background technique
Biological fuel gas is the biomass gas that in the biomass energy conversion system, produces 300～600 ℃ high temperature, and biomass gas needs the valve that can block the gas gas transmission in course of conveying, how to control the defeated of high-temperature gas with high temperature butterfly valve in the existing commercial Application and dies; Yet high temperature butterfly valve is the round metal cartridge type; The valve shaft of butterfly valve is positioned at the center of valve plate, contacts with high-temperature gas is positive for a long time, promptly is in high-temperature area; Valve shaft contacts high temperature for a long time; Be prone to take place deformation, high temperature butterfly valve relies on accurate processing technology to realize better seal, and sealing effect is a greater impact when valve shaft deforms.Mostly high temperature butterfly valve is hard sealing in addition, because the defective of sealing effect difference often appears in the thermal expansion phenomenon of the corrosivity of the biogas under the reducing atmosphere and metal.
The model utility content
The purpose of the utility model provides a kind of above-mentioned shortcoming that overcomes, and valve shaft is positioned at low temperature area, is difficult for taking place axle, valve plate, valve body distortion, high temperature resistant, corrosion resistant high temperature biogas block valve.
The technological scheme that realizes the utility model purpose is: a kind of high temperature biogas block valve, have valve body and valve plate, and valve body is provided with suction port and air outlet, and valve plate is arranged on valve inner, and one of them matches with suction port or air outlet; Said valve plate is hinged through valve shaft and valve body, and valve shaft is arranged on the edge of valve plate;
Above-mentioned high temperature biogas block valve, said valve body is a hexahedron, said suction port is arranged on the different faces with the air outlet;
Above-mentioned high temperature biogas block valve, said suction port is one or more, and said air outlet is a plurality of or one, and suction port and air outlet quantity summation are less than or equal to six;
Above-mentioned high temperature biogas block valve, the periphery of said valve plate is provided with elastic seal ring, and the rounded end of valve plate also is provided with handle, and the handle tail end stretches out valve body;
Above-mentioned high temperature biogas block valve, said valve plate are shaped as circular or square, and the surface of valve plate is provided with stiffening rib;
Above-mentioned high temperature biogas block valve, said valve body has metal shell and thermal-protective coating; The single or double of said valve plate has heat resistant layer;
Above-mentioned high temperature biogas block valve, said valve body is provided with access hole.
The utlity model has positive effect: (1) valve shaft is arranged on valve plate edge, and promptly low-temperature region effectively avoids valve shaft to be in the high-temperature zone for a long time, and valve shaft does not deform, good sealing effect; (2) in valve plate periphery sealing part elastic seal ring is set, realizes soft seal, good sealing effect, high temperature resistant, corrosion-resistant, and stable; (3) valve body adopts the square body shape, can connect different pipelines in the multiaspect upper shed, the aspect, reaches the effect that changes the gas delivery direction in the gas delivery process efficiently.
