Abstract
The utility model relates to a gas-pipeline-network lightning-protection joint, relating to a connector used in gas pipeline, aiming at the deficiency that poor insulation measure is applied to the outdoor gas-transmitting vertical metal pipe of prior residential building, the utility model provides a simple structured gas-pipeline-network lightning-protection joint which can insulate an outdoor gas-transmitting vertical metal pipe against an indoor gas-transmitting metal pipe. The technical proposal adopted is that one end of an insulated pipe 2 is connected between the other end of an inlet steel joint 1 with outer thread and a fixing sleeve 4; the other end of the insulated pipe 2 is connected between the other end of a outlet steel joint 3 with outer thread and the fixing sleeve 4.
Description
One, technical field
The utility model relates to gas pipeline and uses joint, especially a kind of gas ductwork lightning protection joint.
Two, background technique
The residential building outdoor gas carries the upright metallic pipeline all not adopt insulation measures at present, especially in some tall buildings because of construction or multiple factor such as building structure, facilitate the requirement combustion gas to carry the upright metallic pipeline to install on the body of wall out of doors, it is indoor that the combustion gas of the lightning-arrest function of this root forfeiture carries the upright metallic pipeline just thunder may be introduced, and causes the danger of personal injury and property loss.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, can make outdoor gas carry the gas ductwork lightning protection joint that insulate between upright metallic pipeline and the indoor gas transferring metal pipeline.
The technological scheme that the purpose of this utility model adopted is, form by air inlet steel joint, insulation tube, the steel joint of giving vent to anger, fixed cover, it has an end that is connected with insulation tube between the externally threaded air inlet steel joint the other end and the fixed cover, has externally threaded giving vent to anger and is connected with the other end of insulation tube between the steel joint the other end and the fixed cover.
Outdoor gas carried between upright metallic pipeline and the indoor gas transferring metal pipeline the utility model is housed, when installing simultaneously, in its each household wall bushing that is laid in, outdoor gas is carried between upright metallic pipeline and the indoor gas transferring metal pipeline and has just been formed insulation like this, effectively prevents thunderbolt.
The utility model, simple and compact for structure, fabrication and installation are convenient, and cost is low, characteristics such as reliable performance.
Four, description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is the utility model sectional view structural representation.
Among the figure: the 1-air inlet steel joint 2-insulation tube 3-steel joint 4-fixed cover of giving vent to anger
Five, embodiment
As shown in drawings, having between the other end of externally threaded air inlet steel joint 1 and the fixed cover 4 has insulation tube 2, has the other end that insulation tube 2 is arranged between the other end of the externally threaded steel joint 3 of giving vent to anger and the fixed cover 4.
The insulation tube that insulation tube 2 can adopt PE pipe or similar insulating material to make.
