Description
Technical field
The utility model is related to electric heater field, particularly a kind of electric heater liquid heating.
Background technology
Electric heater is made of with liquid heating heating vessel and glass heat-generating pipe, heated liquid storage
In the space to generate heat between pipe outer wall and heating vessel inner wall in glass, glass heat-generating pipe generation heat transfer is heated
Liquid reaches hot water effect.It is stored in the space between glass fever pipe outer wall and heating vessel inner wall due to water,
Between glass heat-generating pipe and heating vessel, this just proposes leakproofness between the two very high requirement.Traditional glass
Glass heat-generating pipe (is sent out including resistance wire quartz glass heat-generating pipe, light wave quartz glass heat-generating pipe and inner cavity plated film electrothermal film glass
Heat pipe) fixation and encapsulating method be：Load onto pipe thread device in glass tube one end, the cuff of the inner tube of pipe thread tightly is in glass
Glass pipe outer tube wall simultaneously fixes glass tube, and the outside thread of pipe thread is then rotated into the interior tooth seal of heating vessel, this
Sample, one end of glass heat-generating pipe, which is immersed inside heating vessel, heats heated liquid.
Traditional glass heat-generating pipe uses pipe thread device to seal, by glass heat-generating pipe lateral wall and pipe thread
Fit closely or increase between the madial wall of pipe allowing property of band (such as rubber washer) washer squeeze after reach sealing and fixed glass
The purpose of glass heat-generating pipe, this sealing means can be caused sealing not tight due to the internal-and external diameter tolerance of glass heat-generating pipe or swarm in glass
The phenomenon that heat-generating pipe, so as to generate explosion leak (leakage) phenomenon,
In addition, also due to glass heat-generating pipe is cylindrical straight tube structure, relies solely on cylindrical outer wall and be equally round
The crowded conjunction mode of the pipe thread inner tubal wall of cylindricality is fixed, also due to glass heat-generating pipe shakes in heated liquid, heats and exhale
Mobile phenomenon caused by suction etc., it is that cylindrical straight tube loosens, and from pipe thread inner tubal wall due to glass that can make to glass heat-generating pipe
Glass heat-generating pipe is loosened from pipe thread inner tubal wall causes leakproofness to be deteriorated, and leakage leak danger of hazardous electrical discharges occurs.
It is not generally pipe spiral shell since the heating tube of most heating vessel installs fixing port in the market to be also
Tooth is fixed, and is largely that common flange mode seals, and to be heated using glass heat-generating pipe, just must particularly customized band pipe spiral shell
The heating vessel of tooth heating gate, also affect have the characteristics that electricity separation, not the glass heat-generating pipe of scaling in electric heating
The popularization and use of hydrophone industry.
In addition, the pipe thread device that glass heat-generating pipe one end is loaded onto increases more than 30% cost of glass heat-generating pipe, it is fixed
Heating vessel price of the system with pipe thread heating gate is also one times or more of conventional flange mouth, has been seriously affected with water power
The price competitiveness in electric heater industry of separation, not the glass heat-generating pipe of scaling feature.
