Description
Technical field
The utility model relates to a kind of safe, clean venting gas appliance of centrifugal pump, for the discharge of gas in centrifugal pump.Carrying secretly or vaporizing with liquid medium during pump housing work, has gas and enters or produce, and then suppress pump, cause the usefulness of pump to decline, until the pump housing damages.Once find to suppress pump, venting gas appliance can be opened and be exhausted, until when exhaust port has the liquid of regime flow to discharge, venting gas appliance cuts out.Belong to coke oven for iron Operation and Maintenance technical field.
Background technique
Centrifugal pump is the capital equipment of liquid medium pressurized delivered, is made up of drive motor, impeller, the pump housing, venting gas appliance and seal arrangement etc.Outlet pipe 2 in existing general venting gas appliance is generally made up of exhaust port 21 and air-exhausting cock 22, as shown in Figure 1, when the pump housing of centrifugal pump 1 need be vented, adjustable air-exhausting cock 22, makes air-exhausting cock 22 be adjusted to above exhaust port 21, in pump, gas, liquid mixture are discharged from exhaust port, when discharging to full liquid, air-exhausting cock is adjusted downward to below exhaust port, closes exhaust port, in exhaust process, waste liquid leaks and can cause the pollution of environment.If the venting gas appliance of this structure is in exhaust process, due to misoperation, air-exhausting cock can occur and throw off, liquid is from exhaust port direct projection, if the poisonous and hazardous medium of high temperature, operator will be caused to scald and pollution to environment.Similar event occurs, and affects very large on safety, environmental protection.
Model utility content
The utility model is a kind of safety exhaust unit of centrifugal pump, when need be vented, is opened by stop valve, and gas can be discharged to exhaust port along outlet pipe, and the waste liquid produced during exhaust enters visualizing liquid reception unit.Adopt this device, when centrifugal pump need be vented, handling safety is reliable, personnel's scald accident can not occur and to environment.Reach handling safety, meet the object of environmental requirement.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of venting gas appliance for centrifugal pump, the cylindrical shell comprising air pipe and be communicated with described air pipe, described cylindrical shell top is provided with top cover, the side of cylindrical shell is provided with outlet valve and liquid discharging valve from top to bottom successively, inner barrel is provided with liquid level float meter and gas-liquid skimming baffle, and described liquid level float meter passes top cover and stretches out.
Preferably, described liquid level float meter top is provided with falling stop block, is provided with liquid-level floater bottom float meter.
Preferably, described liquid level float meter is positioned at the side near outlet valve and liquid discharging valve.
Preferably, described gas-liquid separation baffle plate does not contact with cylinder inboard wall.
Preferably, described air pipe is provided with stop valve.
When the utility model is used for centrifugal pump exhaust, namely easy to operate and safe, can environmental requirement be met again, control flow with open and close stop valve and adjustment aperture, receive waste liquid by Liquid acquisition device, guarantee job safety, environmental protection.In smelter, liquid medium pressurized delivered has all been come by centrifugal pump, and the invention of this device is implemented, easy and simple to handle when can guarantee that centrifugal pump is vented, safety and environmental protection, guarantees the stable smooth operation that logistics is unimpeded, produce.

embodiment
Below in conjunction with accompanying drawing, technological scheme of the present invention is further elaborated.
As shown in Figure 2, the air pipe 3 being provided with stop valve 31 is communicated with the outlet pipe 2 of centrifugal pump 1 by adaptor, cylindrical shell 4 is arranged on the other end of air pipe 3, and be communicated with air pipe 3, cylindrical shell 4 top is provided with top cover 41, cylindrical shell 4 inside is provided with liquid level float meter 42 and gas-liquid skimming baffle 43, and gas-liquid separation baffle plate 43 and gas-liquid separation baffle plate 43 do not contact with the inwall of cylindrical shell 4, gapping interval is had between the inwall of baffle plate 43 and cylindrical shell 4, as shown in Figure 3, gas can be passed through from the both sides of gas-liquid separation baffle plate 43, and liquid intercepts sedimentation by gas-liquid skimming baffle and falls in tank.Liquid level float meter 42 passes top cover 41 and stretches out, and liquid level float meter 42 top is provided with falling stop block 421, when liquid level can be prevented too low, liquid level float meter 42 falls in cylindrical shell, be provided with liquid-level floater 43 bottom liquid level float meter 42, can fluctuate along with fluid level, display liquid level.The side of cylindrical shell 4 is provided with outlet valve 44 and liquid discharging valve 45 from top to bottom successively, and liquid level float meter 42 is positioned at the side near outlet valve 44 and liquid discharging valve 45.
Working principle: when need be vented, stop valve is opened, the mixture of gas and liquid can along outlet pipe to visual gas-liquid separation device, the waste liquid that waste gas carries intercepts sedimentation separation by gas-liquid separation baffle plate and collects, the amount of waste liquid in tank can be floated by liquid-level floater, the height of liquid level float meter shows, and waste gas is discharged by top outlet valve, and waste liquid drains into mobile reception container by liquid discharging valve.Visual gas-liquid separation device convenient disassembly, only need dismantle the clamping bolt of top end cover, can check, overhaul segregating unit.
When the utility model is used for centrifugal pump exhaust, namely easy to operate and safe, can environmental requirement be met again.Control flow with open and close stop valve and adjustment aperture, receive waste liquid by Liquid acquisition device, guarantee job safety, environmental protection.In smelter, liquid medium pressurized delivered has all been come by centrifugal pump, and the invention of this device is implemented, easy and simple to handle when can guarantee that centrifugal pump is vented, safety and environmental protection, guarantees the stable smooth operation that logistics is unimpeded, produce.
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
