Description
Technical field
This utility model relates to the elbow used in a kind of pipe-line system, particularly relates to hot melt elbow。
Background technology
In pipe-line system, elbow is the pipe fitting changing pipeline direction。Angularly divide, have 45 ° and 90 ° 180 ° three kinds the most frequently used, also include other improper angle elbows such as 60 ° of grades according further to requirement of engineering。The material of elbow has cast iron, rustless steel, steel alloy, malleable cast iron, carbon steel, non-ferrous metal and plastics etc.。The mode being connected with pipe has: directly welding (the most frequently used mode) Flange joint, hot-melt adhesive paste, electric smelting connect, threaded and bayonet joint etc.。Can be divided into according to production technology: weld ell, punched bend, push-making angle fitting, casting elbow, butt-welding elbow etc.。
The hot melt elbow of early stage connects generally two ways, and one is outer layer welding mode, carries out hot-melt adhesive paste by the outer layer of pipe and the internal layer of elbow。Another kind is ectonexine welding mode, is namely provided with the birdsmouth between its inside and outside ring wall in one end of elbow, when socket joint connects, is heated the end of pipe and birdsmouth processing, is then injected by pipe in this birdsmouth, pipe can be made to be connected in birdsmouth。
Along with the continuous propelling of Process of Urbanization Construction, the extensive use of combustion gas so that gas pipeline construction and equipment thereof are also required to constantly adapt to the requirement of each side。And the laying of gas pipeline is not straight, but according to different terrain need have different bendings。Therefore, the effect of hot melt elbow just embodies, and it could alter that the direction of gas pipeline。Current gas pipeline is all be laid in the environment in field。When weather is colder time, the combustion gas of pipe interior is very easily easily frozen in, thus damaging pipeline parts, particularly in the position of switching, for instance hot melt elbow junction。The bore abrupt change herein can passed through because of internal flow, internal fluid is very easy to bulk of congealing into。And there is no a kind of technology in the market, it is possible to avoid this situation to occur。Therefore, existing market is continued a kind of hot melt elbow, it is possible to when low temperature, spontaneous heat production, thus preventing from, because of low temperature, contingency occurs。
Utility model content
This utility model is for deficiency of the prior art, it is provided that hot melt elbow, has electro-heat equipment, it is possible to heated up by elbow, thus avoiding the phenomenon that internal duct occurs fluid to condense because of low temperature, thus preventing contingency。
In order to solve above-mentioned technical problem, this utility model is addressed by following technical proposals: hot melt elbow, including elbow main body and connector, described connector is provided with heating ring, is provided with turbine chamber in described elbow main body, in described turbine chamber, is provided with turbine, the outer wall of described elbow main body is provided with microgenerator, described turbine is connected to described microgenerator, and described microgenerator is connected with described heating ring, and described heating ring includes heating wire。
In technique scheme, described microgenerator being provided with temperature-sensitive switch, temperature probe and the described elbow main body of described temperature-sensitive switch contact。
This utility model simple and ingenious structure, has electro-heat equipment, it is possible to heated up by elbow, thus avoiding the phenomenon that internal duct occurs fluid to condense because of low temperature, thus preventing contingency。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model。
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, this utility model is described in further detail: as shown in Figure 1, hot melt elbow, including elbow main body 1 and connector, described connector is provided with heating ring 4, it is provided with turbine chamber 11 in described elbow main body 1, it is provided with turbine 2 in described turbine chamber 11, the outer wall of described elbow main body 1 is provided with microgenerator 3, described turbine 2 is connected to described microgenerator 3, described microgenerator 3 is connected with described heating ring 4, and described heating ring 4 includes heating wire。
Being provided with temperature-sensitive switch on described microgenerator 3, temperature probe and the described elbow main body 1 of described temperature-sensitive switch contact。
The working method of hot melt elbow is stated simply, it is simply that elbow and pipe are integrally connected by welding mode。It is thus desirable to use heater。The heating ring 4 of this device just can play this effect。The heating ring 4 of this device is additionally provided with the lug being connected with external power supply。Heating wire as long as the electric current that the external power supply passed through enters is sufficiently large, in heating ring 4, it becomes possible to by the part fusing of elbow and pipe, thus realizing welding。
And the power of the microgenerator 3 of this device is less, the electric current of generation, it is merely able to so that heating ring 4 heats up, the fluid in prevention pipeline condenses because of low temperature。
When fluid flowing in hot melt elbow time, fluid will drive turbine 2 to rotate。And after turbine 2 rotation, microgenerator 3 will be made to generate electricity。When the temperature in the external world is relatively low time, will making the temperature step-down of hot melt elbow, now temperature-sensitive switch is just triggered thus opening, and electricity produced by such microgenerator 3 will be passed in heating ring 4, heating wire in heating ring 4 is heated up, and this temperature also allowing for hot melt elbow raises。The final phenomenon realizing preventing occurring fluid to condense because of low temperature in hot melt elbow。
In this device, drive turbine 2 to rotate in order to realize fluid flowing, reduce again because turbine 2 must exist so that the resistance weakened of fluid handling capacity, the requirement to the installation site of turbine 2, height very as far as possible。Through experiment repeatedly, finally know according to experimental data, when the center of rotation of turbine 2, be positioned on the diagonal of two connectors, and the maximum outside diameter of the blade of turbine 2 less than lowest calibre in elbow main body 1 time, it is possible to resistance is reduced to minimum。And the maximum outside diameter of blade is more little, resistance is more little。Therefore, in order to take into account, the maximum outside diameter of turbine 2 is generally equivalent to the lowest calibre in elbow main body 1。
Protection domain of the present utility model includes but not limited to embodiment of above; protection domain of the present utility model is as the criterion with claims, and any replacement that those skilled in the art will find apparent that this technology is made, deformation, improvement each fall within protection domain of the present utility model。
This utility model simple and ingenious structure, has electro-heat equipment, it is possible to heated up by elbow, thus avoiding the phenomenon that internal duct occurs fluid to condense because of low temperature, thus preventing contingency。
