Description
Technical field
The utility model relates to a kind of combustion gas lightning protection and to insulate wall-passing pipe.
Background technique
At present, domestic city gas lightning-protection connector is that what to adopt according to CJ/T 385-2011 city gas lightning-protection connector professional standard most enterprises is that Shooting Technique or interior last item shell type are produced.Basic structure is: short metal pipe (weld nipple or the short tube that is threaded), insulating material, lock sleeve, spaghetti, positioning ring.Use and checking through reality, its major defect is: lock sleeve inwall and insulating material connection part, managing easy delamination, wriggling and landing with anti-thunder tube joint when tension load or house majority sedimentation and PE by bending, cause sealability to lose efficacy when causing gas leakage, personal poisoning injures and deaths or run into burning things which may cause a fire disaster and cause the potential safety hazards such as fire.
Therefore, existing combustion gas lightning-protection connector existing defects, needs to improve.
Summary of the invention
The purpose of this utility model improves in the structure of existing combustion gas lightning-protection connector, provide a kind of and engage that sealability is more excellent, switching performance is better, insulating property are better, the life-span is long, economy and the combustion gas lightning protection of freedom from repairs is insulated wall-passing pipe.
Basic conception of the present utility model is: according to the physical property of PE tube material, and adopts advanced cold-extruded technique and special special inside and outside frock respectively by inside and outside for left and right hexagon Threaded Connector Coupling cold-extruded press-in simultaneously PE pipe, and PVC yellow tube is inserted on surface.In order to strengthen insulating property (reinforced insulation resistance value and breakdown voltage value) and the intensity of anti-thunder tube, between PE pipe and pvc pipe, be packed into flexible high-intensity epoxy resin.
The advantage that combustion gas lightning protection insulation wall-passing pipe of the present utility model brings is:
Advantage 1: because PE tubing itself has plasticity and toughness, when the inside and outside Threaded Connector Coupling of left and right hexagon adopts in cold-extrusion technology press-in PE pipe, by the PE material compressed, automatic Compression is full of in joints sleeve and the inside and outside Threaded Connector Coupling of left and right hexagon in horse mouth tooth narrow space, is formed and there is good joint sealability and switching performance.
Advantage 2: due to adopt advanced cold-extruded technique and special inside and outside special tooling assemble, in the process of left and right hexagon inside and outside Threaded Connector Coupling cold-extruded press-in PE pipe, PE tubing is equivalent to receive enough pretightening forces and compress; After Cold Extrusion Process terminates, PE tubing, due to physical properties such as its plasticity toughness, not only can recover and is full of whole space and the switching performance of the joint strengthened and join strength by PE tubing, thus, reach and prevent PE pipe landing and wriggling from joints sleeve.So no matter this product be subject to house or foundation settlement in practice of construction process and actual using process, when being subject to flexural load and tension load, the join strength of this product and sealability are all far superior to top standard of the same trade.
Advantage 3: the insulating property had due to PE tubing, PVC and inner flexible high-intensity epoxy resin of filling itself: 1) insulating resistance value >=10000M Ω; 2) breakdown voltage >=35KV.
Advantage 4: because the working life of PE tubing, PVC and inner flexible high-intensity epoxide resin material of filling reaches 50 years, so this products characteristics has life-span length, freedom from repairs, economy.
Specifically, combustion gas lightning protection insulation wall-passing pipe described in the utility model comprises body, it is characterized in that described body at least by outer silk hex union, left joints sleeve, PE insulation tube, PVC insulation protection tube, right connector cover and internal thread hex union composition, described left joints sleeve is nested with at PE insulation tube one end outer wall, described right connector cover is nested with at PE insulation tube the other end outer wall, described PE insulation tube one end inwall is matched by cold hobbing with outer silk hex union outer wall, described PE insulation tube the other end inwall is matched by cold hobbing with internal thread hex union outer wall, described PVC insulation protection tube is nested with at left joints sleeve, PE insulation tube and right connector cover outer wall.
Flexible high-intensity epoxy resin can also be filled with between PE insulation tube described in the utility model and PVC insulation protection tube.
Compared with the aforementioned existing similar products, combustion gas lightning protection of the present utility model insulation wall-passing pipe engage that sealability is more excellent, switching performance better, insulating property are better, the life-span is long, economy and freedom from repairs.
Content of the present utility model is further described with the following Examples, but content of the present utility model is not limited only to content involved in embodiment.
