A kind of liquid-filled combustion gas occluding device, comprise suction valve and gas outlet valve, it is characterized in that being provided with topping up device body, described topping up device body upper part is connected to liquid feed valve, topping up device body bottom portion is provided with liquid discharging valve, and described suction valve and gas outlet valve are connected the both sides/end of topping up device body respectively.
Described liquid-filled combustion gas occluding device, it is characterized in that described topping up device body is U-tube, described suction valve and gas outlet valve connect two ports of U-tube respectively.
Described liquid-filled combustion gas occluding device, is characterized in that described topping up device body is a closed box body, described suction valve and gas outlet valve is connected to the downward pipe extending to box body bottom.
Described liquid-filled combustion gas occluding device, it is characterized in that being provided with dividing plate in the middle part of described box body, the downward pipe of described suction valve and gas outlet valve is placed in dividing plate both sides respectively, be provided with inverted u-shaped liquid inlet device, the two-port of described liquid inlet device is placed in the both sides of dividing plate respectively, and described liquid feed valve is placed in liquid inlet device top.
Compared with prior art, its structure is simple, effectively can improve repair apparatus and coal (combustion) gas isolation of system for this device, provides reliable and secure guarantee for producing maintenance process; For coal (combustion) gas system overhaul provides more safety measures and means; More powerful guarantees are provided to safety in production.
Accompanying drawing explanation
Fig. 1 is U-shaped structure liquid-filled combustion gas occluding device structural representation;
Fig. 2 is box-type partition apparatus structural representation;
Fig. 3 is the box-type partition apparatus structural representation being provided with dividing plate.
In figure, 1-combustion gas is responsible for; 2-suction valve; 3-liquid feed valve; 4-topping up device body; 5-liquid discharging valve; 6-gas outlet valve; The downward pipe of 7-; 8-dividing plate; 9-liquid inlet device.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, two fractures of combustion gas supervisor 1 are hinged with by suction valve 2 and gas outlet valve 6 the topping up device body 4 of a U-shape, the top air inlet valve side tipping liquid feed valve 3 of this topping up device body, the bottom of topping up device body is hinged with a liquid discharging valve 5, do not have liquid in topping up device body 4 under normality, liquid feed valve 3 and liquid discharging valve 5 are closed, and suction valve 2 and gas outlet valve 6 are opened, combustion gas is passed through through topping up device body, normal air feed.During maintenance, close suction valve and gas outlet valve, open liquid feed valve, in the topping up device body 4 of U-shape, combustion gas thoroughly blocks after being full of by liquid, ensures that gas equipment enters without combustion gas.After maintenance, first open bottom liquid discharging valve 5, ensure that liquid feed valve is closed, close liquid discharging valve after liquid emptying in topping up device body, open suction valve and gas outlet valve, pipeline recovers normal air feed simultaneously.
Shown in Fig. 2, topping up device body 4 is a closed box body, circular or square or other shape.Suction valve 2 and gas outlet valve 6 are provided with downward pipe 7, and liquid feed valve is arranged on box body top, and liquid discharging valve is arranged on bottom box body.Do not have liquid in normality lower box body, combustion gas is entered the fuel gas pipeline entering gas equipment in box body from the downward pipe of gas outlet valve by the downward pipe of suction valve, during maintenance, suction valve and gas outlet valve are closed, open liquid feed valve 3, when liquid is higher than two downward mouths of pipe, namely reaches and thoroughly close combustion gas requirement.Overhaul complete, open liquid in the emptying box body of liquid discharging valve and recover normal for gaseity.
In Fig. 3, topping up device body installs a dividing plate 8 in the box body shown in Fig. 2 additional, and box body is divided into completely isolated two-part, simultaneously, arrange an inverted U-shaped tubulose liquid inlet device 9, two ports of this liquid inlet device are placed in dividing plate both sides respectively, and liquid feed valve 3 is arranged on liquid inlet device top.Do not have liquid in normality lower box body, combustion gas enters box body side by suction valve, and the U-shaped pipe through liquid inlet device 9 enters another box body opposite side, enters gas equipment by gas outlet valve 6.During maintenance, close suction valve and gas outlet valve, open liquid feed valve, liquid is full of box body both sides, thorough blocking-up combustion gas, overhauls complete, opens liquid discharging valve, the whole emptying rear closedown liquid discharging valve of liquid of box body both sides and liquid feed valve, open towards air valve and gas outlet valve, and pipeline recovers normal for gaseity.
Liquid-filled combustion gas occluding device of the present utility model can be used for the accessory of gas-fired equipment air inlet pipeline, and also can be used as air delivering pipeline maintenance, maintenance etc. needs on the pipeline of cut-out.
Liquid-filled combustion gas occluding device of the present utility model can be used for gas equipment air inlet pipeline as accessory, and on the pipeline that caliber is less, be installed at coal (combustion) gas system needs
In topping up device body, institute's topping up body adopts water usually, as special circumstances can adopt other liquid.
By reference to the accompanying drawings this device is explained in detail above, but this device is not limited in above-described embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from this device aim.
