Abstract
The utility model discloses a double-layer bypass valve of dust remover in order to solve the problems that the bypass valve of the prior dust remover is easy to leak and deposit ash, wherein, a place with a certain distance below a lifting valve plate (5) is provided with a lower lifting valve plate (6); the lifting valve plate (5) is connected with the lower lifting valve plate (6) through a lifting rod (2); an air outlet of a hot air pipe (4) is arranged between the lifting valve plate (5) and the lower lifting valve plate (6); an air outlet inside an air duct (1) is provided with a valve seat (7) showing a step shape from the view of section plane. Therefore, the utility model has the advantages that the utility model can effectively prevent dust leakage, and is simple to operate as well as convenient to maintain.
Description
Affiliated technical field the utility model relates to a kind of by-pass valve that is used for the deduster of control atmosphere pollution.Relate in particular to a kind of by the air channel, promote the double-deck by-pass valve of the deduster that valve plate, cylinder, warm-air pipe form.
Background technique
At present, a kind of like this by-pass valve of deduster is disclosed on the market, its structural feature is: the double-deck by-pass valve of deduster, form by air channel, lifting valve plate, cylinder and warm-air pipe, in the air channel, be provided with the lifting valve plate, promoting valve plate is connected with cylinder outside being arranged on the air channel, warm-air pipe is arranged in the air channel, be provided with valve seat at lifting valve plate and exhaust outlet contacting point, air channel, the end face of valve seat is provided with sealing gasket, when the needs bypass operation, can start cylinder, promote valve plate, make flue gas be short-circuited to air channel row to atmosphere from inlet box.But, leak because this structure easily produces dust, so that the deduster discharging exceeds standard, in addition, do not open for a long time owing to promote valve plate, deposit thick dust on every side, inefficacy easily again makes the bypass air channel can not bring into play its effect preferably when needs are opened.
Summary of the invention
The purpose of this utility model provides a kind of difficult generation dust and leaks, again the double-deck by-pass valve of the deduster that can conveniently open.
For achieving the above object, the double-deck by-pass valve of the utility model deduster, by the air channel, promote valve plate, cylinder and warm-air pipe are formed, in the air channel, be provided with the lifting valve plate, promoting valve plate is connected with cylinder outside being arranged on the air channel, warm-air pipe is arranged in the air channel, be provided with valve seat at lifting valve plate and exhaust outlet contacting point, air channel, the end face of valve seat is provided with sealing gasket, under being provided with, the place that promotes certain distance below the valve plate promotes valve plate, promote valve plate and be connected with the following valve plate that promotes by lifting arm, the exhaust outlet of warm-air pipe is arranged on and promotes valve plate and following the lifting between the valve plate, and the exhaust outlet in the air channel is provided with from section and sees stepped valve seat.
Under to promote valve plate littler than promoting valve plate, and on the axis that coexists, promote valve plate and contact with the big sleeveless jacket end face of valve seat, following lifting valve plate contacts with the little sleeveless jacket end face of the valve seat that is provided with sealing gasket.
After adopting this structure,, make the malleation hot blast be injected into two and promote between the valve plates, and produce invisible air curtain one, intercepted flue gas in the deduster effectively from bypass leakage owing to promote the exhaust outlet that is provided with warm-air pipe between the valve plate at two.Simultaneously, also removed the dust of poppet valve panel area effectively.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is the main cross-sectional schematic of the double-deck by-pass valve of the utility model deduster.
Among the figure: 1. the air channel, 2. lifting arm, 3. cylinder, 4. warm-air pipe, 5. promote valve plate, 6. time promote valve plate, 7. valve seat, 8. little sleeveless jacket, 9. big sleeveless jacket.
Embodiment
Shown in the accompanying drawing, the double-deck by-pass valve of deduster, by air channel (1), promote valve plate (5), cylinder (3) and warm-air pipe (4) are formed, in air channel (1), be provided with and promote valve plate (5), promoting valve plate (5) cylinder (3) outer with being arranged on air channel (1) is connected, warm-air pipe (4) is arranged in the air channel (1), be provided with valve seat (7) in lifting valve plate (5) and exhaust outlet contacting point, air channel (1), the end face of valve seat (7) is provided with sealing gasket, be provided with lifting valve plate (6) down in the place that promotes valve plate (5) below certain distance, promoting valve plate (5) is connected with the following valve plate (6) that promotes by lifting arm (2), the exhaust outlet of warm-air pipe (4) is arranged on and promotes valve plate (5) and following the lifting between the valve plate (6), and the exhaust outlet in air channel (1) is provided with from section and sees stepped valve seat (7); Under to promote valve plate (6) littler than promoting valve plate (5), and on the axis that coexists, promote valve plate (5) and contact with big sleeveless jacket (9) end face of valve seat (7), following lifting valve plate (6) contacts with little sleeveless jacket (8) end face of the valve seat that is provided with sealing gasket (7).
When the deduster proper functioning, lifting valve plate (5) and the following valve plate (6) that promotes are in closed condition, and inject the malleation hot blast by warm-air pipe (4).When the needs bypass operation, can open simultaneously and promote valve plate (5) and the following valve plate (6) that promotes, flue gas then is short-circuited to draught flue from inlet box.
Claims (2)
