Abstract
The utility model relates to a smoke desulfurizing venetian blind type single-layer double sealing baffle plate door for a smoke pipe. The smoke desulfurizing venetian blind type single-layer double sealing baffle plate door is composed of a valve body and blind baffle plates connected with the valve shaft on the valve body. The valve shaft and the blind baffle plates on the valve shaft are on the valve body. A pneumatic device drives the valve shaft and the blind baffle plates on the valve shaft to rotate to realize the opening or the closing. Simultaneously, metal sealing striking flakes are arranged on the blind baffle plates, and double layer sealing is formed between the metal sealing striking flakes on the two blind baffle plates. The leakage of the smoke can be cut off by 100 percent. The smoke desulfurizing venetian blind type single-layer double sealing baffle plate door of the utility model has reliable operation and long service life; the smoke desulfurizing venetian blind type single-layer double sealing baffle plate door is favorable for the installation, the repair and the maintenance for smoke desulfurizing units.
Description
One, technical field;
The utility model relates to valve, specially refers to the valve in the flue.
Two, prior art:
In today of industrialization high development, urgently it needs a bright day to people.Yet thermal power generation industry and metallurgy industry have been discharged the gas of a large amount of sulfur-bearings in the flue, and it can form acid rain, causes serious pollution to atmosphere.The flue gas desulfurization unit can be handled the sulfurous gas in the flue, but, once after this unit breaks down, gas baffle door must switch to flue gas rapidly in other desulfurization unit, prevent smoke spillage in order to avoid cause air pollution, existing gas baffle door can not satisfy the requirement of desulfurization unit fully because sealing is relatively poor.
Two, technology contents:
The utility model is to provide the flue gas desulfurization venetian blind type individual layer double containment baffle door at a kind of import that is placed in the flue gas desulfurization unit, outlet, bypass place, blocks flue gas or allow the valve of flue gas communication port and good airproof performance in flue.
The technical solution of the utility model realizes as follows:
The utility model comprises: the blinds baffle plate (2) on valve body (1) and the valve body (1), it is characterized in that: respectively there is a pneumatic means (6) on the both sides of valve body (1), one of them pneumatic means (6) is in valve body (1) upper end, and another pneumatic means is in the lower end of valve body (1); Valve shaft (3) is connected on the valve body (1), and blinds baffle plate (2) is connected on the valve shaft (3), and each bent axle (3) links to each other with pneumatic means (6) by connecting rod (5), crank (4); The pneumatic means (6) on valve body (1) top links to each other with the some bent axles in valve body (1) top (3), and the pneumatic means of its underpart (6) links to each other with some bent axles (3) of bottom, and sealing shell fragment (9) is connected on the blinds baffle plate (2).
Sealing shell fragment (9) is made of stainless steel, between every two-layer stainless steel one deck graphite flake is arranged.
Advantage of the present utility model is as follows:
1. make 90 ° of quick rotation simultaneously because the utility model adopts pneumatic means can drive a plurality of blinds baffle plates, make a plurality of blinds baffle plates open simultaneously or close in 3 seconds, it is reliable.
2. because sealing ring of the present utility model seals shell fragment for the multilayer stainless steel and sealing surface is the conical surface, and between every two-layer sealing shell fragment one deck graphite flake is arranged, can guarantee that sealing is tight, simultaneously, formed aeroseal between the sealing shell fragment on per two blinds baffle plates, this double-layer seal is more reliable, simultaneously, but sealing air is spacer medium again, and reaching does not have leakage fully.
3. because the utility model is installed in the import of flue gas desulfurization unit, outlet, bypass place, when unit maintenance, can be in flue 100% block flue gas, guarantee that flue gas does not have leakage, make unit maintenance, easy to maintenance.
Four, description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model A-A cutaway view;
Fig. 3 is I place enlarged drawing.
Five, specific embodiment:
Among Fig. 1: the right and left of valve body (1) respectively has a pneumatic means (6), one of them pneumatic means (6) is on the top on valve body (1) the right, another pneumatic means (6) is in the bottom on valve body (1) left side, 8 valve shafts (3) are connected on the valve body (1), each blinds baffle plate (2) is connected on each valve shaft (3), 4 valve shafts (3) on valve body (1) top link to each other with the pneumatic means (6) of the bottom of valve body (1) by connecting rod (5), 4 valve shafts (3) of valve body (1) bottom link to each other with the pneumatic means (6) on the top of valve body (1) by connecting rod (5), during work, two pneumatic means (6) are swing clockwise, drivening rod (5) rotates simultaneously, connecting rod (5) drives 8 valve shafts (3), and the blinds baffle plate (2) on 8 valve shafts (3) rotates simultaneously, blinds baffle plate (2) is opened, having served as bar (5) 8 valve shafts of drive (3) rotates when transporting to 90 °, blinds baffle plate (2) on 8 valve shafts (3) is all opened, medium can all circulate, when 2 pneumatic means (6) when rotating counterclockwise, drivening rod (5), crank (4) rotates simultaneously, connecting rod (5) crank (4), 8 valve shafts (3) on the drive valve body (1) and the blinds baffle plate (2) on 8 valve shafts (3) rotate simultaneously, blinds baffle plate (2) is closed, when connecting rod (5), when crank (4) drives 8 valve shafts (3) return, blinds baffle plate (2) Close All on 8 valve shafts (3), medium can all block.
Among Fig. 2: the passage (7,8) between valve body (1), blinds baffle plate (2), the two seals.
Among Fig. 3: blinds baffle plate (2), sealing shell fragment (9), sealing shell fragment (9) is made of stainless steel, between per two stainless steel layers one deck hundred ink sheets are arranged, make sealing tighter, bolt (10) will seal shell fragment (9) and fixedly fix on the blinds baffle plate (2), form hermetic seal between two groups of sealings shell fragments (9), but just spacer medium.
Claims (2)
1. a flue gas desulfurization venetian blind type individual layer double containment baffle door comprises: the blinds baffle plate (2) on valve body (1) and the valve body (1), it is characterized in that: respectively there is a pneumatic means (6) on the both sides of valve body (1), one of them pneumatic means (6) is in valve body (1) upper end, and another pneumatic means is in the lower end of valve body (1); Valve shaft (3) is connected on the valve body (1), and blinds baffle plate (2) is connected on the valve shaft (3), and each bent axle (3) links to each other with pneumatic means (6) by connecting rod (5), crank (4); The pneumatic means (6) on valve body (1) top links to each other with the some bent axles in valve body (1) top (3), and the pneumatic means of its underpart (6) links to each other with some bent axles (3) of bottom, and sealing shell fragment (9) is connected on the blinds baffle plate (2).
