Pipeline fluid peeping device with air inflowing and pressure stabilizing function

Abstract

The invention belongs to the technical field of pipeline internal observation, and particularly relates to a pipeline fluid peeping device with an air inflowing and pressure stabilizing function. The device comprises a four-way pipe body, window flanges, tempered glass and an air inlet valve, wherein the four-way pipe body is provided with an upper cylinder and a lower cylinder and is connected with a system pipeline. A left cylinder and a right cylinder of the four-way pipe body are connected with the two window flanges correspondingly, the tempered glass is installed on and fixed to the edges of the left cylinder and the right cylinder of the four-way pipe body through the window flanges, and an open hole is formed in the upper portion of the four-way pipe body and connected with the air inlet valve. The device has the air inflowing function, avoids the phenomenon of local negative pressure in a pipeline while achieving the function of observing the flowing state of fluid in the pipeline and equivalently has the advantage that a fluid source system and a receiving system form an obvious disconnection point through a funnel ; and when positive pressure exists in the pipeline, an air inlet can be closed through a sealing ball, the fluid is prevented from leaking outwards, and other devices are prevented from being wetted or industrial safety risks are avoided.

technical field [0001] The invention belongs to the technical field of pipeline internal observation, and in particular relates to a pipeline fluid peeping device with an intake air pressure stabilizing function. Background technique [0002] In industrial production, there are many applications that use funnels to receive fluids. The advantage of funnels is that the fluid source system and the receiving system form a clear disconnection point, which is convenient for observing the flow state of the fluid. The disadvantage is that due to improper flow adjustment, the upstream and downstream The flow does not match, causing the overflow of the funnel to occur from time to time.

[0002] In industrial production, there are many applications that use funnels to receive fluids. The advantage of funnels is that the fluid source system and the receiving system form a clear disconnection point, which is convenient for observing the flow state of the fluid. The disadvantage is that due to improper flow adjustment, the upstream and downstream The flow does not match, causing the overflow of the funnel to occur from time to time

[0003] Taking fluid water as an example, the capacity of the funnel to receive is not only related to the upstream and downstream flow matching, but also affected by the water temperature. The high-temperature water discharge funnel will generate a large amount of steam, which not only causes the loss of the medium, but also has industrial safety hazards of scalding personnel. risk

For systems that need to observe the working state of the fluid, the traditional transformation method is generally to change the funnel into a pipe with a peep window. After transformation, the pipe is a fully enclosed structure. The funnel is generally arranged vertically up and down. When the fluid in the pipeline flows due to the action of gravity, the flow velocity of the fluid in the pipeline will be accelerated. When the pipeline is long enough, a negative pressure section will be formed in the closed pipeline. If there is no air entering, the water in the pipeline will be difficult to empty. ; Usually the closed peephole is filled with water. If the water is transparent, the flow state of the water cannot be monitored, and the meaning of adding peepholes is lost.
