Description
Technical field
The utility model relates to a kind of flap valve, and specifically a kind of furnace cupola overhead type automatic turning plate valve belongs to the technical field of gas chamber obturator.
Background technology
The coal-gas recovering utilization of furnace cupola, be mainly used in all multipurposes such as cold wind heat exchange, heating boiler, how traditional coal gas collection is drawn and is waited acquisition mode by bell seal fan, and because traditional bell type seals, it is indoor that water-cooled plunger cylinder is placed in furnace roof coal gas of high temperature completely, work under bad environment, the easy air amount of coal gas air-introduced machine, operation comparatively bothers operating personnel's technical merit is required to extra-high-speed, and production safety is difficult to ensure, and equipment investment is large, energy consumption is high, later stage maintenance difficulty is all larger.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of furnace cupola overhead type automatic turning plate valve, can effectively solve the comparatively technical barrier such as trouble of the easy air amount of coal gas air-introduced machine and operation.
To achieve these goals, a kind of furnace cupola overhead type automatic turning plate valve that the utility model adopts, is characterized in that, described flap valve comprises valve plate, valve plate rotating shaft, actuating arm and weight arm; Described valve plate inside is the structure of hollow, the inside of described valve plate is provided with dividing plate, described valve plate rotating shaft is fixed on valve plate body and utilizes bearing rotary, one end of described valve plate rotating shaft has water inlet, the structure that described valve plate rotating shaft is hollow, the other end of described valve plate rotating shaft has delivery port, and one end that described valve plate rotating shaft is provided with delivery port is connecting actuating arm, and one end that described valve plate rotating shaft is provided with water inlet is connecting weight arm; One end of described actuating arm adopts key axle sleeve to be connected with one end of weight arm.
Described flap valve also comprises and being used in conjunction with it and external cylinder, adopts pin to be connected between described cylinder and actuating arm.
Between described water inlet and delivery port and water pipe, adopt respectively high-pressure hose to be connected.
Described valve plate rotating shaft and the employing of body of heater joint portion are high temperature resistant, wear-resistant ceramic fiber packing seals.
Compared with prior art, the utility model is simple in structure, easy to operate, and flap valve executing agency adopts double acting Direct Travel cylinder, to guarantee that on fire door lower surface and flap valve, plane is airtight all the time, also be convenient to realize automation control, running performance is reliable and stable, because gas chamber sealing is better, coal gas collection does not need additionally to increase air-introduced machine, rely on blast in stove just coal gas can be sent into heat exchanger, improved the security of work on the spot environment, save power consumption.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of furnace cupola overhead type automatic turning plate valve, this flap valve comprises valve plate 1, valve plate rotating shaft 2, actuating arm 3 and weight arm 4. This valve plate 1 inside is the structure of hollow, is formed by heat-resisting steel sheet and plate welding, and the inside of valve plate 1 is provided with dividing plate 7, and dividing plate 7 can effectively prevent that cooling water from, from water inlet 5 flows into, directly discharging from delivery port 6, has reduced cooling effect. Cooling water, from water inlet 5 flows to, through the gap between dividing plate 7 and valve plate 1 inwall, and then is discharged through delivery port 6. Valve plate rotating shaft 2 is fixed on valve plate 1 and utilizes bearing rotary. The structure that valve plate rotating shaft 2 is hollow, one end has water inlet 5, and the other end has delivery port 6, injects circulating water by hollow valve plate rotating shaft 2, and flatness that can holding member, can be because of high temperature deformation. One end that valve plate rotating shaft 2 is provided with delivery port 6 is fixed wtih actuating arm 3, and one end that valve plate rotating shaft 2 is provided with water inlet 5 is fixed wtih weight arm 4. One end of actuating arm 3 adopts key axle sleeve to be connected with one end of weight arm 4. All structural assemblies are supported by two side shaft holders, and bearing block adopts bolt to be fixedly connected on gas chamber outside, maintenance for convenience detach.
Further, flap valve also comprises and being used in conjunction with it and external cylinder, adopts pin to be connected between cylinder and actuating arm 3. Cylinder is external not to be needed separately to do cooling, and is convenient to M R.
Further, between water inlet 5 and delivery port 6 and water pipe, adopt respectively high-pressure hose to be connected, so not only durable, and also easy to maintenance.
Further, valve plate rotating shaft 2 is high temperature resistant with the employing of body of heater joint portion, wear-resistant ceramic fiber packing seals, and can make coal gas, dust not occur leaking outside, meanwhile, and convenient maintenance and replacement.
Above embodiment is only to explanation of the present utility model, and it is not to restriction of the present utility model. For a person skilled in the art, it still can be modified to the technical scheme of recording in previous embodiment, or is equal to replacement. All in spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
