Abstract

The utility model relates to a device for monitoring material flow inside a pipeline, namely a flow monitoring device, which comprises a transparent vision pipe. The diameter of the vision pipe is identical to that of a material conveying pipeline, and the vision pipe is connected in series into the pipeline and is a partial pipe body of the material conveying pipeline. An operator can clearly see material flowing states inside the pipeline through the transparent vision pipe so as to decide whether materials are completed in conveying and decide starting and stopping of a conveying device. The flow monitoring device has the advantages of low cost and extremely convenient installation and utilization, and is particularly suitable for occasions with large material viscosity and low flow control precision requirement.

Description

The flow monitoring device

Technical field

The utility model relates to the device that is used to observe the mass flow in the pipeline.

Background technique

Flow commonly used on the material conveying pipe in the existing Chemical Manufacture is in respect of rotameter, restriction flowmeter, volume-displacement, electromagnetic flowmeter, ultrasonic flowmeter etc., but the common cost of these flowmeters is higher, and in the higher occasion of material viscosity, flowmeter stops up easily and influences ordinary production.

Summary of the invention

It is low that the purpose of this utility model just provides a kind of installation cost, and flow monitoring device easy to use.

The scheme that adopts is exactly a kind of flow monitoring device, comprises one section transparent pipe of looking, and the caliber of looking pipe is identical and be connected in the pipeline with the caliber of material conveying pipe.

As shown from the above technical solution, flow monitoring device of the present utility model comprises that is mainly looked a pipe, look on the pipeline that pipe is connected on mass transport, and caliber and the pipeline of looking pipe coincide, therefore look a part of body that pipe constitutes material conveying pipe, and to look pipe be transparent, operator see through this and look the Flow of Goods and Materials situation that pipe just can be clear that pipeline is interior so, whether carry the start and stop that finish and determine conveying equipment with the decision material, such flow monitoring installation cost is low, install and use all easily, be particularly suitable in material viscosity big, but the less demanding occasion of flow control accuracy is used.

Description of drawings

Fig. 1 is a user mode reference drawing of the present utility model.

Embodiment

In the production system as shown in Figure 1, be communicated with by pipeline 2 and the fluid pump 3 that is arranged on the pipeline 2 between the reactor 1 of upstream process and the reactor 5 of lower procedure, start fluid pump 3 like this, fluid pump 3 can carry out subsequent reactions with the material in the upstream reactor 1 in pipeline 2 is transported to the reactor 5 of lower procedure, usually on the pipeline 2 valve 6 is set also, so that the break-make of pilot line.For this production system easy to use, the utility model provides a kind of flow monitoring device, is used to be arranged into pipeline 2, and this device comprises one section transparent pipe 8 of looking, such pipe 8 of looking is connected in the pipeline 2, that is to say and look a bit of pipeline that pipe 8 constitutes FLUID TRANSPORTATION.Obviously, the caliber of looking pipe 8 equals the caliber of pipeline 2, perhaps be slightly larger than or be slightly less than the caliber of pipeline 2 so that connect with pipeline 2, but both internal diameter difference can not be excessive, look solid accumulation in the pipe 8 to avoid looking excessive the causing of pipe 8 calibers, be unfavorable for observing the Flow of Goods and Materials situation; Perhaps look too small pipeline 2 putties that cause of pipe 8 internal diameters.Start like this after the fluid pump 3, see through the mobility status of looking pipe 8 observation materials and can judge the working condition of fluid pump 3, so that in time find the unusual condition of fluid pump 3, maintenance in time; Can in time find again simultaneously material whether pumping finish, with the start and stop of decision fluid pump 3, avoid fluid pump 3 idle running and cause security incident.Such flow monitoring apparatus structure is simple, is easy to manufacturing, installation and maintenance, and is very easy to use.

Further, looking pipe 8 can adopt composite to reduce cost, look pipe 8 or pipeline 2 for fear of looking to take place to vibrate to destroy when pipe 8 changes because of mass flow with pipeline 2, an end and the pipeline 2 of looking pipe 8 are flexible coupling, as shown in Figure 1, an end of looking pipe 8 connects flexible pipe 7, flexible pipe 7 is affixed with pipeline 2, and flexible pipe 7 can be plastic flexible pipe or bellows, perhaps looks pipe 8 two ends and all is flexible coupling with pipeline 2, looking like this between pipe 8 and the pipeline 2 has the leeway that relatively moves, and avoids both to be damaged; Simultaneously, the length of flexible pipe 7 can be stretched, and avoids looking that the length of reserving on the length of pipe 8 and flexible pipe 7 and the pipeline 2 misfits and the situation that is difficult to install.Described valve 6 preferably is positioned at flexible pipe 7 and looks the upstream position of pipe 8, so that by pipeline, pipe 8 or flexible pipe 7 are looked in maintenance or replacing.

As from the foregoing, flow monitoring installation cost of the present utility model is low, installs and uses all easily, is particularly suitable for the less demanding occasion of, flow control accuracy big in material viscosity and uses.
