Technical Field
The invention belongs to the technical field of pipeline observation, and particularly relates to a pipeline fluid peeping device with air inlet and pressure stabilizing functions.
Background
In industrial production, a plurality of applications of receiving fluid by using a funnel have the advantages that a fluid source system and a receiving system form an obvious disconnection point, the through-flow state of the fluid is convenient to observe, and the defects that the upstream flow and the downstream flow are not matched due to improper flow regulation, so that the phenomenon of overflow of the funnel is caused to happen occasionally.
Taking fluid water as an example, the receiving capacity of the funnel is not only related to the flow matching between the upstream and downstream, but also affected by the temperature of the water, and the high-temperature water discharging funnel can generate a large amount of steam, which not only causes the loss of media, but also has the industrial safety risk of scalding personnel. For a system with a requirement for observing the working state of fluid, the traditional transformation method is generally to change a funnel into a pipeline with a peep window, the pipeline is of a fully-closed structure after transformation, the funnel is generally vertically arranged from top to bottom, the flow velocity of fluid in the pipeline can be accelerated due to the action of gravity when the fluid in the vertically arranged pipeline flows, when the pipeline is long enough, a negative pressure section can be formed in the closed pipeline, and if no air enters the pipeline, water in the pipeline is difficult to evacuate; the closed peephole is filled with water, if the water is transparent, the flowing state of the water cannot be monitored, and the significance of increasing the peephole is lost.
Therefore, it is desirable to provide a fluid peeping device with air inlet pressure stabilizing function for pipeline, so as to solve the problems in the prior art.
