Abstract
The utility model relates to a double-valve integrated straight-through stop valve assembly which comprises a first stop valve, a second stop valve, an air inlet channel, a flow channel and an air outlet channel. The aperture of the first stop valve is smaller than that of the second stop valve, the air inlet channel is communicated with a valve port of the first stop valve and a valve port of the second stop valve, an upper cavity of the first stop valve is connected with an upper cavity of the second stop valve by the flow channel, and the upper cavity of the second stop valve is connected with the air outlet channel. The double-valve integrated straight-through stop valve assembly has the advantages that the two stop valves with the different apertures are connected with each other, so that flow resistance of media can be reduced, the double-valve integrated straight-through stop valve assembly can be conveniently controlled in a centralized manner, the media can be timely replenished when alternate control is carried out by actuators, and stable reversing effects can be realized; the double-valve integrated straight-through stop valve assembly is small in mounting space, the manufacturing and mounting costs can be saved, pipelines can be simplified, connection points can be reduced, accordingly, leakage points can be decreased, and the service efficiency can be improved.
Description
Technical field
The utility model relates to a kind of central controlled composite structure straight-through stop valve door, relates in particular to two valve integrated straight-through type cut-off coupling valves.
Background technique
China generally adopts straight-through stop valve to control combustion gas on industrial furnace combustion control system at present, when needing large and small fire to switch, adopt the large small-bore different monomer valve of two covers to control.Its medium and small valve is controlled little fire, and large valve is controlled big fire.Large and small fire is alternately controlled mutually.This monomer valve needs the independent pipeline of controlling of two covers, and two lines open altogether in same combustion gas contact and finally collect in before burner.This controlling method, pipeline is many and need do a plurality of bendings, and the circulating resistance of medium is large.Before burner, joint has a segment distance apart from valve port, when while alternately controlling, medium can differ from, fills into, and commutates not steady.On large-scale stove, generally need to arrange a lot of burners in addition, the space length between burner is very near.So each burner is arranged two covers and is controlled pipeline and seem too intensive, is unfavorable for the maintenance overhaul of burner place equipment.Two cover pipeline first line of a couplet contacts are many, increased possibility leakage point, have potential safety hazard, and meanwhile, installation cost is also higher.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of two valve integrated straight-through types and ends coupling valve, and medium flow resistance is little, and centralized control is simplified pipeline.
For achieving the above object, the utility model is achieved through the following technical solutions:
Two valve integrated straight-through type cut-off coupling valves, comprise stop valve one, stop valve two, intake duct, runner, air outlet channel, stop valve one bore is less than stop valve two bores, intake duct communicates with stop valve one, stop valve two valve ports, the epicoele of stop valve one is connected by runner with the epicoele of stop valve two, and the epicoele of stop valve two is connected with air outlet channel.
Described stop valve one, stop valve two are equipped with final controlling element.
Compared with prior art, the beneficial effects of the utility model are:
By two different stop valves of bore are connected, reduced medium flow resistance, be convenient to centralized control, while utilizing final controlling element alternately to control, medium fills in time, and commutation is steadily.Installing space is little, saves and makes and installation cost, has simplified pipeline, reduces interface, and then has reduced leakage point, has improved utilization efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-intake duct 2-valve port one 3-runner 4-valve port two 5-air outlet channel 6-final controlling element one 7-final controlling element two.
Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following mode of execution.
See Fig. 1, two valve integrated straight-through type cut-off coupling valves, comprise stop valve one, stop valve two, intake duct 1, runner 3, air outlet channel 5, stop valve one bore is less than stop valve two bores, intake duct 1 communicates with stop valve one, stop valve two valve ports, the epicoele of stop valve one is connected by runner 3 with the epicoele of stop valve two, and the epicoele of stop valve two is connected with air outlet channel 5.Stop valve one, stop valve two are equipped with final controlling element.
During use, medium flows into from intake duct 1, and when needs carry out little fire control when processed, final controlling element 27 is closed valve port 24, and final controlling element 1 is by valve port one 2 unlatchings.Medium enters stop valve one epicoele and through runner 3, pours stop valve two epicoeles again, then flows out through air outlet channel 5.When needs carry out Control large fire, final controlling element 27 is opened valve port 24, and final controlling element 1 is closed valve port 1.Medium enters stop valve two epicoeles, then flows out through air outlet channel 5.This mode is steady while alternately controlling, and while closing, two final controlling element are closed two valve ports simultaneously.
The utility model, by two different stop valves of bore are connected, has reduced medium flow resistance, is convenient to centralized control, and while utilizing final controlling element alternately to control, medium fills in time, and commutation steadily.Installing space is little, saves and makes and installation cost, has simplified pipeline, reduces interface, and then has reduced leakage point, has improved utilization efficiency.
