Abstract
The utility model belongs to an auxiliary device of a heat accumulating type combustion system, and relates to a four-way change valve which is a reversing device on an air and smoke gas pipeline. The utility model is characterized in that the four-way change valve is mainly composed of a valve body, a valve shaft, a valve plate, four door frame type sealing baffle plates, and an actuator. The main body of the valve body is an oblong barrel body, and the four walls of the barrel body are welded with round barrels and round flanges. The four door frame type sealing baffle plates are welded in the barrel body of the valve body. The valve shaft is connected with the valve plate through a conical pin. The connecting parts of valve body and other parts are all provided with sealing devices. The actuator is connected with the valve shaft through a key. The utility model has the advantages of small size, simple fabrication, convenient operation and maintenance, good sealing performance, short reversing time, and reliable performance.
Description
The utility model belongs to the regenerative combustion system accessory, is the reversing arrangement on air, the fume pipe---four-way change-over valve.
Regenerative combustion system in the past adopts repid cut-off valve.The air of one cover burner, flue gas commutation need four repid cut-off valves, and installation and maintenance are very inconvenient.Also have and adopt two five-way valves to control, but its equipment volume is huge, leak rate is higher.
The utility model provides a kind of four-way change-over valve, and it is connected with burner A, B and air, fume pipe, and the two states by this valve makes burner A, B alternately be in burning, accumulation of heat state.But can organize the burning purpose of preheated air again thereby reach regenerative combustion system.
For achieving the above object, the utility model is realized by following scheme:
A kind of four-way change-over valve is characterized in that this four-way change-over valve mainly is made up of valve body, valve shaft, valve plate, door case type sealing baffle, final controlling element, and the valve body main body is a rectangular cylindrical shell, and its end face is square; On the wall of cylindrical shell, be welded with cylinder and round flange, be connected with A, B burner and air, fume pipe by this flange; Four door case type sealing baffles that stud with the ceramic fiber kernmantle are welded in the inner barrel of valve body; Valve shaft is connected by taper pin with valve plate, and valve body and miscellaneous part joint are equipped with seal arrangement, and final controlling element is connected by key with valve shaft.
Characteristics of the present utility model are: volume is little, makes simply, and installation, operation and maintenance are all very convenient, and good airproof performance, and turn around time is short, reliable performance.

Fig. 2 is four-way change-over valve structural representation I
Fig. 3 is four-way change-over valve structural representation II
Embodiment:
See Fig. 1, the utility model four-way change-over valve be connected with burner A, B and air conduit K, fume pipe Y that the two states by this valve makes burner A, B alternately be in burning, accumulation of heat state.When four-way change-over valve was in state a, burner A was in combustion regime, and burner B is in the accumulation of heat state; When four-way change-over valve was in state b, burner A was in the accumulation of heat state, and burner B is in combustion regime.
See Fig. 2, Fig. 3, four-way change-over valve is connected with burner A, B and air conduit K, fume pipe Y respectively by the round flange on the valve body 2.Be enclosed within a pair of door case type sealing baffle 1 that is diagonal position in valve plate 4 and the valve body on the valve shaft 3 during state a and be close to, this moment, air conduit K and burner A, fume pipe Y and burner B formed passage respectively.Start final controlling element 5, drive valve shaft 3 and make valve plate 4 be rotated counterclockwise 90 °, another is to tightly driving fit of door case type sealing baffle 1 in valve plate 4 and the valve body.This moment, fume pipe Y and burner A, air conduit K and burner B formed passage respectively, and four-way change-over valve is in state b.Restart final controlling element 5, drive valve shaft 3 and make valve plate 4 turn clockwise 90 °, four-way change-over valve is got back to state a again.Air conduit K and burner A, fume pipe Y and burner B, fume pipe Y and burner A, air conduit K and burner B alternately form passage, go round and begin again, and reach the purpose of burner A, B alternate combustion, accumulation of heat.
