Description
Technical field
The utility model relates to gas burning fields, and in particular to a kind of city gas seamless steel standpipe for avoiding lightning stroke.
Background technique
Combustion gas is the general name of gaseous fuel, it can burn and release heat, is used for city dweller and industrial enterprise, combustion gas
Type it is very much, mainly have natural gas, manufactured gas, manufactured fuel gas, liquefied petroleum gas and biogas, coal gas, by the source of combustion gas, usually may be used
Combustion gas is divided into natural gas, manufactured gas, manufactured fuel gas, liquefied petroleum gas and biogas etc., China's gas supply industry and developed country
Compared to starting late, the combustion gas of dispatching mainly includes coal gas, liquefied petroleum gas and three kinds of natural gas.
In recent years, with the fast development of natural gas, gas user quantity is sharply increased, the quantity of gas pipeline and facility
Also it increase accordingly, but since the attached gas pipeline of building is not mostly instead of by designing unit's integrated design of building,
By combustion gas Specialty Design, institute individually carries out late design, so, the attached gas pipeline of buildings in general is not included in building
Whole lightning-protection system, gas pipeline Lightning Protection tend to ignore.
In recent years, being continuously increased due to skyscraper, is limited by fire-fighting and other factors, and gas supply pipeline is usual
Outside building then installation enters back into interior to roofing.Currently, metal tube is largely used in gas supply pipeline, by
In this kind of pipe fitting and pipe not within the protection scope of building lightning protection facility, therefore, room should be entered in gas supply pipeline
Interior place carries out insulation technology processing, avoids and prevent harm caused by due to lightning stroke.
Existing gas pipeline often installs lightning proof, but existing lightning proof one with outdoor junction indoors
As it is directly exposed be installed in outdoor environment, therefore lightning proof is directly exposed in air and directly by day in use process
Solarization drenches with rain, and is easy to cause biggish attrition and attack to insulation tube piece, is unfavorable for prolonging its service life, and works as and avoid being struck by lightning
Lightning protection device when being damaged, be easy that safety accident occurs to gas pipeline.
Utility model content
Technical problem to be solved in the utility model be existing gas pipeline when in use, cannot be preferably to interior
With outdoor junction installation lightning proof protected, service efficiency it is lower, and it is an object of the present invention to provide it is a kind of avoid lightning stroke
City gas seamless steel standpipe solves the problems, such as the use for avoiding the gas pipeline of lightning stroke.
The utility model is achieved through the following technical solutions:
A kind of city gas seamless steel standpipe for avoiding lightning stroke, including vertical insulation tube, the both ends of insulation tube are and absolutely
One end of edge connector connects, and the other end of two insulating joints is respectively connected with metal connecting tube, the outside of two metal connecting tubes
Face is set with fixed plate at insulating joint, be respectively connected between two fixed plates insulating joint adjacent thereto it is several can
Flexible spring lever along the vertical direction is connected with flexible rubber sleeve between two fixed plates, and rubber sleeve is sleeved on insulation
On the lateral surface of pipe and insulating joint, two fixed plates can be slided under the action of spring lever along the lateral surface of metal connecting tube.
Further, when in use, insulation tube is seamless steel standpipe to the present apparatus, is located outside use, the both ends of insulation tube
The insulating joint of connection is also located outside simultaneously, and the other end and indoor pipeline of the metal connecting tube of insulating joint connection connect
It connects, the insulation tube and insulating joint of the present apparatus form lightning-arrest pipeline, and when used for a long time, lightning-arrest pipeline is chronically exposed to outer, meeting
It damages, influences service life.
Fixed plate is arranged in the present apparatus on it, and fixed plate is sleeved on metal connecting tube, when in use, can be according to actually making
With situation, when the distance between the fixed plate of lower section and ground shorten, fixed plate under the effect of external force, along metal connecting tube
Lateral surface move up, shorten the distance between two fixed plates, and then adapt to different installation situations.
Meanwhile rubber sleeve is set between two fixed plates of the present apparatus, can further to the present apparatus take shelter from the thunder pipeline into
Row protection, prevents dust, sewage etc. from entering, while when the distance between two fixed plates is adjusted, due to rubber tackling
It is flexible, therefore the adjusting of the distance between flexible and two fixed plates that will not influence rubber sleeve, service efficiency is more
Height is more advantageous to long-term adjustment use.
Preferably, a kind of city gas seamless steel standpipe for avoiding lightning stroke, fixed plate are flexible rubber material.Gu
Fixed board and rubber sleeve are the arc-shaped of side opening, and fixed plate is concentric circles, and the internal diameter of fixed plate is connected less than metal
The diameter of pipe, the diameter greater than rubber sleeve of the outer diameter of fixed plate.Fixed plate and rubber sleeve are the arc-shaped of side opening, therefore
When in use, directly the fixed plate of the present apparatus can be sleeved on metal connecting tube, not many and diverse operation, and due to fixation
Plate has elasticity, therefore after being set with, can not only fix stably, and install and use all convenient, will not be easy from metallic conduit
It slides, service efficiency is higher.
Preferably, the diameter of a kind of city gas seamless steel standpipe for avoiding lightning stroke, rubber sleeve is greater than the straight of insulating joint
Diameter.The diameter of rubber sleeve is greater than the diameter of insulating joint, so when in use, preset space between rubber sleeve and lightning-arrest pipeline,
It is more advantageous to the lightning-arrest pipeline of protection, is more convenient for being used for a long time.
Preferably, a kind of city gas seamless steel standpipe for avoiding lightning stroke, rubber sleeve includes the first rubber layer from outside to inside
With the second rubber layer, several small through hole are provided in the first rubber layer, several large through-holes, and are provided in the second rubber layer
One rubber layer and small through hole in the second rubber layer and large through-hole are staggered.The rubber sleeve of the present apparatus is set as two layers, and
The small through hole and large through-hole being staggered are respectively set on two layers, the lightning-arrest pipeline being more advantageous in rubber sleeve in this way carries out scattered
Heat, and such setting also effectively can avoid sewage from entering in rubber sleeve, be more advantageous to and protect to lightning-arrest pipeline, mention
High service efficiency.
