Abstract

The utility model discloses a pipeline pressure measuring device. The pipeline pressure measuring device includes a pipeline, and is characterized in that two or more branch pipes are disposed on an outer pipe wall of the pipeline; one end of each branch pipe is fixed to the pipe wall while the other end is connected with a pressure equalizing pipe; a lead-out pipe is disposed on the pressure equalizing pipe; and the pipeline is communicated with the branch pipes, the pressure equalizing pipe and the lead-out pipe. Each of the branch pipes, the pressure equalizing pipe and the lead-out pipe is an integrated structure. The pipeline pressure measuring device is simple in structure. By adopting a mode of arranging the branch pipes and the pressure equalizing pipe on the outer wall of the pipeline and a method of introducing a gas in the pipeline into the pressure equalizing pipe for measurement, the pipeline pressure measuring device avoids high-standard requirements of an measuring gauge in direct measurement, the measurement cost is reduced, and meanwhile the influence on a pipe network is small.

Description

A kind of pipeline pressure tester
Technical field
The utility model relates to a kind of pipeline pressure tester.
Technical background
Many shared device engineerings, as air conditioner, dedusting, gas supply, the engineerings such as chemical plant exhaust, need to carry fluid be assigned to each relevant equipment or space, or from each receiving station, fluid collection be got up to be transported to specified point.In the process of carrying, often due to many reasons, make the assignment of traffic of some pipeline section in pipe network not meet design load.Pipeline section actual flow in this pipe network system and design discharge inconsistency, be called hydraulic misadjustment.
In system, the flow of arbitrary pipeline section changes, and will inevitably cause that the flow of other pipeline sections changes.Some loop is because hydraulic misadjustment and flow is too small or excessive, and ventilating system in this way, can cause system airflow tissue turbulence, and dust pelletizing system can cause partial points dust removing effects to worsen.In order to alleviate or avoid the hydraulic misadjustment of pipe network system, often according to the requirement of end, pressure and the flow of measuring instrument (flowmeter, thermometer, pressure gauge etc.) to pipe network is installed on pipe network and monitored, according to the data of monitoring, pipe network is adjusted accordingly.But in some pipe network, such as dedusting pipe network, pumped (conveying) medium is the gas of high wearing and tearing, and testing environment is more severe, and common measurement instrument is difficult to adapt to such working environment.Greatly reduce the serviceable life of instrument.
Utility model content
Content of the present utility model is to provide one and is suitable for tonometric dedusting pipe network.
To achieve these goals, by the following technical solutions: a kind of pipeline pressure tester, comprise pipeline, it is characterized in that: outside described pipeline, on tube wall, be provided with arm, one end of arm is fixed on tube wall, the other end and balance pipe join, and are provided with fairlead on balance pipe, and pipeline communicates with arm, balance pipe and fairlead.
As further optimization, in order to facilitate the gas in pipeline to enter balance pipe, the quantity of described arm is more than 2 or 2.
As further optimization, to install for convenient, described arm, balance pipe and fairlead are integral type structure.
As further optimization, in order to prevent when the gaging pressure not, the leakage of gas, the exit of described fairlead is provided with the ring flange that contains closure plate.
The utility model is simple in structure, by having adopted the mode that arm and balance pipe are set on the outer wall of dedusting pipe network, gas in pipeline is introduced to the method that balance pipe is measured again, high standard requirement to measurement instrument while having avoided direct measurement, reduce measurement cost, simultaneously less on the impact of pipe network.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, a kind of pipeline pressure tester, comprises pipeline 1, outside pipeline, on tube wall, have through hole, one end of arm 2 is connected with balance pipe 3, and the other end is welded in through hole, on balance pipe 3, be provided with fairlead 4, the outlet of fairlead 4 is provided with the ring flange 5 that contains closure plate.In this embodiment, the quantity of arm is 6, and balance pipe has played the effect of all pressing here.
When gaging pressure, ring flange 5 is opened, the rubber hose 6 of pressure measuring instruments 7 is positioned in balance pipe by fairlead.Because pipeline communicates with arm, balance pipe and fairlead, so just can measure the pressure in cleaning shaft.
After measurement, rubber hose is taken out, fix ring flange.
Wherein arm, balance pipe and fairlead can be integral type structure, more convenient while installation like this, have also prevented the gas leakage problem that split-type design is brought simultaneously.
