Abstract
The utility model relates to a multi-tightness three-way change valve which comprises a valve body, a first level packing groove, a first level pressing cap, a second packing groove, a second pressing cap, pneumatic actuating mechanisms and valve plates. The first packing groove and the second packing groove are symmetrically arranged in the surface of the valve body, the tops of the first packing groove and the second packing groove are respectively provided with the first level pressing cap and the second level pressing cap. The number of the pneumatic actuating mechanisms and the number of the valve plates are both two, one of the pneumatic actuating mechanisms penetrates through the first level pressing cap and the first level packing groove and is connected with one valve plate inside the valve body, and the other pneumatic actuating mechanism penetrates through the first level pressing cap and the first level packing groove and is connected with the other valve plate inside the valve body. Compared with the prior art, the multi-tightness three-way change valve has the advantages of being low in cost, simple in structure, reasonable in design, convenient to use and stable and reliable in performance. Zero leakage of blast furnace gas and the personal safety of field staff are effectively guaranteed, and production cost is lowered.
Description
Technical field
The utility model relates to the regenerative combustion technology field, particularly a kind of many sealings three-way diverter valve.
Background technique
At present, heat accumulating burner capable is to utilize heat-storage type fume residual heat recovering device, alternately switch air or gaseous fuel and flue gas, make it the heat retainer of flowing through, can reclaim to the full extent the sensible heat of high-temperature flue gas, temperature of exhaust fume can drop to below 180 ℃, combustion-supporting medium or gaseous fuel can be preheating to more than 1000 ℃, form the novel flame type different from traditional flame, and make in the stove temperature distribution more even by reversing combustion, this firing unit and environmental protection are energy-conservation again, but it is fuel that most heat accumulating burner capables adopt blast furnace gas, because blast furnace gas contains toxic substance CO, therefore requires change-over valve must have good sealing, require valve interiorly to leak, more can not leak outside.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, easy to use, guarantee that blast furnace gas zero is revealed, three-way diverter valve stable and reliable for performance.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of many sealings three-way diverter valve, comprise valve body, the one-level packing groove, the one-level gland, the secondary packing groove, the secondary gland, pneumatic actuator and valve plate, described valve body surface is arranged with one-level packing groove and secondary packing groove, one-level packing groove and secondary packing groove top are respectively equipped with one-level gland and secondary gland, pneumatic actuator and valve plate all have two, one of them pneumatic actuator passes the one-level gland and is connected with a valve plate of valve inner with the one-level packing groove, and another pneumatic actuator passes the secondary gland and is connected with another valve plate of valve inner with the secondary packing groove.
Described one-level packing groove inside is provided with the one-level filler.
Described secondary packing groove inside is provided with the secondary filler.
Described valve plate both sides are respectively equipped with primary seal circle and secondary seal circle.
Compared with prior art, the beneficial effects of the utility model are:
A kind of many sealings three-way diverter valve, have cost characteristics low, simple in structure, reasonable in design, easy to use, stable and reliable for performance, because valve plate is provided with two seal rings, stoped in the blast furnace gas and leaked, all be placed with filler owing in every grade the packing groove simultaneously, and compress filler by gland, the filler radial expansion is filled up the gap and has been prevented that blast furnace gas from leaking outside, guaranteed that effectively blast furnace gas zero is revealed and Field Force's personal safety, reduced cost of production.
Description of drawings
Fig. 1 is structural drawing of the present utility model.
1-valve body, 2-one-level packing groove, 3-one-level filler, 4-one-level gland, 5-secondary packing groove, 6-secondary filler, 7-secondary gland, 8-pneumatic actuator, 9-primary seal circle, 10-valve plate, 11-secondary seal circle
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further specified:
As shown in Figure 1, a kind of many sealings three-way diverter valve of the utility model, comprise valve body 1, one-level packing groove 2, one-level gland 4, secondary packing groove 5, secondary gland 7, pneumatic actuator 8 and valve plate 10, valve body 1 surface is arranged with one-level packing groove 2 and secondary packing groove 5, one-level packing groove 2 and secondary packing groove 5 tops are respectively equipped with one-level gland 4 and secondary gland 7, pneumatic actuator 8 and valve plate 10 all have two, one of them pneumatic actuator 8 passes one-level gland 4 and is connected with a valve plate 10 of valve body 1 inside with one-level packing groove 2, another pneumatic actuator 8 passes secondary gland 7 and is connected with another valve plate 10 of valve body 1 inside with secondary packing groove 8, one-level packing groove 2 inside are provided with one-level filler 3, secondary packing groove 5 inside are provided with secondary filler 6, and valve plate 10 both sides are respectively equipped with primary seal circle 9 and secondary seal circle 11.
When valve plate 10 is in closed condition, by pneumatic actuator 8 valve plate 10 and valve body 1 are compressed, this moment, primary seal circle 9 and secondary seal circle 11 played the effect of sealing, effectively stoped the interior leakage of blast furnace gas; And all be placed with filler in every grade the packing groove, and compress filler by gland, the gap is filled up in the filler radial expansion, so just forms the two seals structure, can effectively prevent leaking outside of blast furnace gas.
Above described only be basic principle of the present utility model, be not that the utility model is imposed any restrictions, everyly according to the utility model it is carried out equivalent variations and modification, all within the category of the art of this patent protection scheme.
Claims (4)
