The coke oven gas pipe of reduction equipment input cost surveys pressure and takes mouth structure.
In order to achieve the above purposes, the technical solution adopted by the utility model is:, and a kind of coke oven gas pipe surveys pressure that mouth is taken to tie
Structure, including gas piping, the gas piping side wall are equipped with an opening, further include a short circuit cylinder, the short circuit cylinder one end fits
The length of insertion opening is 20-30mm, and is shorted the position that drum outer wall is contacted with opening and is equipped with weld seam；The short circuit cylinder other end
Equipped with bottom plate, a connecting pipe is inserted into the middle part of bottom plate along with the short circuit consistent direction of cylinder axis from outside, and connecting pipe is inserted into bottom plate
Length be 20-30mm, the other end of the connecting pipe connect with a pressure instrumentation, and the connecting pipe is equipped with valve.
The risk that impurity surprisingly flows into short circuit cylinder is had if being shorted cylinder and being obliquely installed, it is preferred that in the short circuit cylinder
Axis is vertical with gas piping.
Preferably, the diameter for being shorted cylinder is 150mm, and the diameter of connecting pipe is 10mm.Using such dimension scale
It can guarantee that the air pressure for entering connecting pipe is more stable, also prevent the impurity such as tar, ammonium hydroxide and be directly entered connecting pipe.
Preferably, the opening and short circuit cylinder are all round.Circular opening and short circuit cylinder are easy to process, and junction does not have
There are corner angle, increase the stability of welding, avoids junction stress after being used for a long time that generation fracture is concentrated to lead to gas leak.
In use, valve can be opened, the coal gas in gas piping can enter short circuit cylinder from the opening of side wall, then from short
Connect cylinder enters the connecting pipe being attached thereto, and pressure instrumentation can directly measure the pressure of coal gas in connecting pipe.In this course,
The part that short circuit cylinder protrudes into opening can be avoided the impurity such as tar, the ammonium hydroxide that gas piping tube wall flows down and enter in short circuit cylinder,
It is shorted in cylinder even if there is minimal amount of impurity to enter, is inserted into bottom plate from outside equipped with bottom plate, connecting pipe due to being shorted the cylinder other end
In, bottom plate can also stop impurity to enter in connecting pipe, avoid impurity from entering and contact with the pressure-sensitive diaphragm of pressure instrumentation, to avoid
Pressure-sensitive diaphragm will not be influenced by burn into the measurement accuracy of pressure.Diameter due to being shorted cylinder and connecting pipe successively decreases step by step,
The air pressure that coal gas is formed after being shorted cylinder and entering in connecting pipe is more stable, and the impact of gas will not be such that the pressure of instrument measurement occurs
Fluctuation.
Pressure remained steady that the utility model can be such that coal gas contacts with pressure instrumentation will not influence normal pressure inspection
It surveys；The part that short circuit cylinder protrudes into opening can be avoided the impurity such as tar, the ammonium hydroxide that gas piping tube wall flows down and enter short circuit cylinder
In, bottom plate also effectively can stop impurity to enter in connecting pipe, prevent contact of the impurity with pressure instrumentation, will not corrode pressure membrane
Piece increases the service life of pressure gauge, reduces equipment input cost, also ensures the time that device operates normally, mentions
Working efficiency is risen；Also reduce the maintenance load of instrument work.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure, 1. gas pipings, 11. openings, 2. are shorted cylinder, 21. bottom plates, 3. connecting pipes, 31. valves, 4. pressure instrumentations.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown, a kind of coke oven gas pipe, which surveys pressure, takes mouth structure, including gas piping 1,1 side wall of gas piping
It further include a short circuit cylinder 2 equipped with an opening 11, the length for being shorted 2 one end fits insertion opening 11 of cylinder is 20-30mm, and
It is shorted the position that 2 outer wall of cylinder is contacted with opening 11 and is equipped with weld seam；2 other end of short circuit cylinder is equipped with bottom plate 21,3 edge of a connecting pipe
It is inserted into 21 middle part of bottom plate from outside with the consistent direction of 2 axis of cylinder is shorted, and it is 20- that connecting pipe 3, which is inserted into the length of bottom plate 21,
30mm, the other end of the connecting pipe 3 are connect with a pressure instrumentation 4, and the connecting pipe 3 is equipped with valve 31.
The risk that impurity surprisingly flows into short circuit cylinder 2 is had if being shorted cylinder 2 and being obliquely installed, it is preferred that the short circuit cylinder 2
Central axes are vertical with gas piping 1.
Preferably, the diameter for being shorted cylinder 2 is 150mm, and the diameter of connecting pipe 3 is 10mm.Using such size ratio
