Technical field
The utility model relates to dam work model test testing field, especially one kind is exclusively used in hydraulic depression tank instrument and meter
The concentration penetrating structure of line.
Background technique
As the sustainable development of world's Dam constructions technology is broken through, high dam flood-discharge energy-dissipating security protection task is more and more tighter
It is high.Wherein, the force reduction pool bottom destruction, aerial drainage vibration in power station, flood discharging tunnel cavitation erosion, atomization landslide and pressure pulsations etc.
Problem has obtained the concern and attention of industry, and " in terms of energy dissipating protection, vibration control, atomization prediction, air mixing corrosion reducing
Achieve breakthrough achievement.The high-volume construction and later period operation in High aititude power station, have largely expanded water conservancy project decompression
The test function of case.Traditional hydraulic depression tank is mainly used for inverting or previews the cavitation and cavitation erosion research of dam work discharge structure；Mould
Type test is designed referring to " flow cavitation model test regulation " SL156-2010；Vacuum degree is based on gravity phase in hydraulic depression tank case
Like criterion and cavitation number equal configuration.For carrying out the hydraulic depression tank of High aititude power station hydrodynamic simulation, in chamber
Vacuum degree is based on the corresponding atmospheric pressure design of practical height above sea level, can be used for carrying out the hydraulics characteristics such as pulse pressure, vibration, aeration, atomization
The ambient pressure response characteristic research of index.Therefore, the test equipment that hydraulic depression tank uses is related to sensor.It is all kinds of
Often there is larger difference in the instrument line model and output end aviation plug model of sensor.If using hydraulic depression tank body point
Formula aperture threading method is dissipated, single perforated area is difficult to adapt to the threading demand of various line style instrument, and is replacing or dismantling instrument
The leakproofness of cabinet is difficult to ensure after device.Particularly with the high end sensor of instrument line and output end integrated design, need out
The area in hole increases, and sealing difficulty is big.Therefore, the current demand towards the comprehensive hydraulic indexes cooperative determining of hydraulic depression tank,
The utility model proposes a kind of concentration penetrating structures for being exclusively used in hydraulic depression tank instrument and meter line.
Summary of the invention
The utility model is to solve technical problem present in well-known technique and provide one kind and be exclusively used in hydraulic depression tank instrument
The concentration penetrating structure of instruments and meters line, the structure can realize instrument under the premise of ensureing decompression cabinet leakproofness and structure safety
The concentration of instruments and meters line installs.
The utility model is adopted the technical scheme that solve technical problem present in well-known technique: one kind is exclusively used in
The concentration penetrating structure of hydraulic depression tank instrument and meter line, including the threading basal disc being packed on decompression cabinet observation window opening, in institute
It states and is provided with centre bore on threading basal disc, thread threading sealing cylinder is coated in the centre bore, is set on the inside of the threading basal disc
There is connection reinforcement ring, the connection reinforcement ring set is on the thread threading sealing cylinder, the thread threading sealing cylinder and the threading base
Pass through high strength structure glue-line between disk and the connection reinforcement ring and between the threading basal disc and the connection reinforcement ring
Connection, more instrument and meter lines pass through the thread threading sealing cylinder, and are fixed on the thread threading sealing using pressure bearing and seal putty column
In cylinder, plugging structure is equipped in the inner end of the thread threading sealing cylinder.
The threading basal disc is using made of steel plate, and the thread threading sealing cylinder and the connection reinforcement ring are to use to have
Made of machine glass.
Threading demarcation plate is equipped in the thread threading sealing cylinder.
The plugging structure is formed using industrial plasticine.
The utility model has the advantages and positive effects of: the structure directly can have observation window opening using decompression cabinet and pacify
Dress, decompression cabinet are not necessarily to extra openings；More instrument and meter lines first concentrate outlet again, are not limited by instrument type, without disassembly
Connector, instrument and meter precision is unaffected, existing outlet built in a large amount of instrument and meters can be overcome in hydraulic depression tank to set hole more
The difficult problem with threading can effectively solve the problems, such as cabinet threading pressure-bearing property and leakproofness, and ensure the structure safety of decompression cabinet.
And the utility model convenient disassembly, secondary using unaffected, structure is simple, easy to process, and installation is convenient, cost
Low, high recycling rate does not influence the structural stability and leakproofness of hydraulic depression tank, there is preferable practicability.
