Abstract
The utility model discloses an emergency nitrogen supply control gas circuit structure. The structure mainly adopts the technical scheme that an emergency nitrogen inlet valve assembly is connected with the lower part of a first gas circuit, a first pneumatic butterfly valve assembly is connected with the lower part of a second gas circuit, a second pneumatic butterfly valve assembly is connected with the lower part of a third gas circuit, and the above parts are assembled into a whole through a connecting pipeline; a second ball valve is connected with one end of a control pipeline, and a first ball valve is connected with the other end of the control pipeline; the second ball valve is arranged in the connecting pipeline above emergency nitrogen inlet valves in a connected manner; and the middle of the control pipeline is connected and communicated with the space above first pneumatic butterfly valves and second pneumatic butterfly valves, and is integrated with the space through assembly. The structure has the advantages of reasonable design and convenience in use, and can guarantee the nitrogen supply for continuous production.
Description
Affiliated technical field
The utility model relates to the operating structure of the urgent nitrogen supply system of a kind of annealing furnace, and is particularly a kind of urgent for nitrogen control gas circuit structure, is applicable to annealing furnace.
Background technology
At present, when the gas shield station power outage and nitrogen gas generating system take place is broken down, promptly can only enter annealing furnace from gas circuit one, can't supply with proportioning gas, cause production line to stop production for nitrogen.
Summary of the invention
Problem to be solved in the utility model is, overcomes the deficiencies in the prior art, provides a kind of urgent for nitrogen control gas circuit structure.This structure is not only reasonable in design, compact construction, and urgent nitrogen can be entered simultaneously from gas circuit one and gas circuit two, and guaranteeing the supply of nitrogen, simultaneously urgent nitrogen enters matching system by gas circuit three, guarantees carrying out continuously of production.
The technical solution adopted in the utility model is: gas circuit connects urgent nitrogen inlet valve assembly once, two times companies of gas circuit Pneumatic butterfly valve one assembly is connected Pneumatic butterfly valve two assemblies for three times with gas circuit, by the connection line general assembly is one, control pipeline one end connects ball valve two, the other end connects ball valve one, ball valve two is connected in the connection line of urgent nitrogen inlet valve top, control pipeline intermediate section is not connected with Pneumatic butterfly valve one, Pneumatic butterfly valve two tops, is assembled into one and constitutes.
During use, the utility model is connected with the liquid nitrogen vaporization device of urgent nitrogen gets final product.In the ordinary production, ball valve two is closed, ball valve one is opened and is got final product; When needing the urgent nitrogen of supply, ball valve one is closed, ball valve two is opened.Owing on Pneumatic butterfly valve one, the Pneumatic butterfly valve two hand-operating device is arranged all, when outage, can supply urgent nitrogen, guarantee carrying out continuously of production.
The beneficial effects of the utility model are, and are rational in infrastructure, easy to use, when outage and nitrogen gas generating system break down, can supply urgent nitrogen, and what guarantee to produce carries out continuously.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Accompanying drawing number is: 1, urgent nitrogen inlet valve, 2, Pneumatic butterfly valve one, 3, Pneumatic butterfly valve two, 4, ball valve one, 5, the liquid nitrogen vaporization device of ball valve two, 6, urgent nitrogen, 7, the control pipeline, 8, gas circuit one, 9, gas circuit two, 10, gas circuit three, 11, connection line.
Embodiment
With reference to Fig. 1, gas circuit connects urgent nitrogen inlet valve 1 assembly for one 8 times, 29 times companies of gas circuit Pneumatic butterfly valve one 2 assemblies are connected Pneumatic butterfly valve 23 assemblies for 3 10 times with gas circuit, by connection line 11 general assemblies is one, control pipeline 7 one ends connect ball valve 25, the other end connects ball valve 1, ball valve 25 is connected in the connection line 11 of urgent nitrogen inlet valve 1 top, is connected with Pneumatic butterfly valve 1, Pneumatic butterfly valve 23 tops respectively in the middle of the control pipeline 7, is assembled into one and constitutes.
During use, the utility model is connected with the liquid nitrogen vaporization device 6 of urgent nitrogen gets final product.In the ordinary production, ball valve 25 is closed, ball valve 1 is opened and is got final product; When needing the urgent nitrogen of supply, ball valve 1 is closed, ball valve 25 is opened.Owing on the Pneumatic butterfly valve 1, Pneumatic butterfly valve 23 hand-operating device is arranged all, when outage and nitrogen gas generating system break down, can supply urgent nitrogen.
The urgent constructional feature of the utility model design: this architecture compactness for nitrogen control gas circuit structure, cost is low, overcomes the deficiency of original technology, and a kind of new gas path control method is provided, urgent nitrogen can be entered simultaneously from gas circuit 1 and gas circuit 29, guarantee the supply of nitrogen; During the nitrogen gas generating system fault of short period of time, can make urgent nitrogen normal for nitrogen from gas circuit 1, simultaneously urgent nitrogen enters matching system by gas circuit 3 10, and what guarantee to produce carries out continuously.
