Abstract
The utility model discloses an end socket sealing member of a defrosting electric heating pipe used for cold storage warehouses and cold cupboards. The utility model is characterized in that an electric heating pipe (3) is matched with a heating wire eduction rod (1), and the space between a heating wire and the eduction rod is filled with magnesia powder (2); insulating sealing compound (4) is coated on the end socket of the electric heating pipe, the eduction rod (1) and a power cord (7) are connected by a copper pipe casting die (6), and synthetic rubber (5) and the end socket of the electric heating pipe are arranged in a die mold and are pressed by certain temperature and pressure; then, the sealing member is formed. The sealing member fundamentally overcomes the lethal defects that as the end socket of the original electric heating pipe is matched with a rubber sleeve, clearance is formed, and the sealing property, the dampproof property and the freezing resistance of the end socket of the electric heating pipe are poor. The sealing member is widely suitable for refrigeration equipment which has extremely high humidity and work in low temperature environment, such as the cold storage warehouses and the cold cupboards.
Description
The utility model defrosting electrothermal tube termination seal is a kind of freezer, high, following defrosting electrothermal tube of working of low temperature environment of refrigerator wetness of being used for.
At present, the refrigeration facility of China's refrigeration industry freezes, frosting phenomenon and cause poor refrigerating efficiency, had a strong impact on giving full play to of refrigeration facility functions such as freezer, refrigerator, after particularly the defrosting electrothermal tube is damaged on the import refrigeration plant, refrigeration plant can not be run well, not only cost an arm and a leg to covering a mouthful defrosting electrothermal tube abroad again, and very inconvenient.Past people is for solving deicing, the defrosting problem on the refrigeration plant, generally adopt to add and join rubber sleeve in the electrothermal tube termination, because after this rubber sleeve is mixed, though reach the purpose of defrosting to a certain extent, owing to have certain clearance between electrothermal tube heating wire and the rubber sleeve, cause this electrothermal tube termination sealing, insulating properties relatively poor, seriously influence refrigeration, not only cause the equipment breakdown that electrothermal tube burns, and insulation property are poor, can cause the personal safety accident.
At the shortcoming of above-mentioned existence, the utility model provides a kind of have protection against the tide, freeze proof, anti-aging, rubber and the good defrosting electrothermal tube termination seal of electrothermal tube metal bonding that insulation resistance value is high.
The construction features of the utility model electrothermal tube termination seal are that electrothermal tube (3) is furnished with heating wire eduction rod (1), moistureproof magnesia powder (2) is housed between electrothermal tube (3) and the heating wire, purpose plays conducts heat and insulating effect, scribble insulator seal chewing-gum (4) in the electrothermal tube termination, heating wire eduction rod (1) is connected by copper pipe casting die (6) with power line (7), to aggregate into rubber 5 and electrothermal tube termination and be placed in the lump in the pressing mold, be pressed into electrothermal tube termination seal by certain temperature and pressure.
The advantage of the utility model protection against the tide, freeze proof defrosting electrothermal tube termination seal is as follows: the strong good seal performance of cohesive force of (one) electrothermal tube metal and rubber, and because of it adopts CH
3COCH
3, CHELOK205, CHELOK220, be applied to metal successively, generally can not come off without chemical treatment, the bonding of metal and rubber and good seal performance have overcome the deadly defect of former employing electrothermal tube adapted rubber interplanting defrosting electrothermal tube termination sealing, protection against the tide, freeze proof weak effect.(2) this synthetic rubber has good protection against the tide, freeze proof, heat-resisting, anticorrosion, performance such as anti-aging, is applicable to the work down of humidity, low temperature environment, long service life.(3) high pressure resistant, insulation resistance is high, safe and reliable.Its damp attitude insulation resistance 〉=200-∞ M Ω; Insulation resistance behind the humid heat test 〉=5M Ω; So tide attitude leakage current :≤0.1MA is safe and reliable.(4) be equipped with this termination seal electrothermal tube every technical indicator all with Russia, like product produced in USA roughly the same, and price has only 1/10th of Russia, like product produced in USA.The of the present utility model creation successfully can substitute the defrosting electrothermal tube on the import equipment, for country has saved a large amount of foreign exchanges, for China's refrigeration industry has solved a great problem.
Fig. 1 is the structural representation of the utility model defrosting electrothermal tube termination seal.
Among the figure: 1, heating wire eduction rod; 2, magnesia powder; 3, electrothermal tube; 4, insulator seal chewing-gum; 5, synthetic rubber; 6, copper pipe casting die; 7, power line.
Below in conjunction with Fig. 1 enforcement of the present utility model is described further:
Is furnished with heating wire eduction rod (1) at electrothermal tube (3), moistureproof magnesia powder (2) is housed between electrothermal tube and the heating wire, heating wire eduction rod (1) is connected by copper pipe casting die (6) with power line (7), on the electrothermal tube termination, scribble insulator seal chewing-gum (4) then, be placed in the pressing mold with synthetic rubber, be suppressed into defrosting electrothermal tube termination seal by certain temperature and pressure.
Claims (1)
- A kind of freezer that is used for, the refrigerator wetness is high, low temperature environment is the defrosting electrothermal tube termination seal of work down, mainly by heating wire eduction rod 1, magnesia powder 2, electrothermal tube 3, insulator seal chewing-gum 4, synthetic rubber 5, copper pipe casting die 6, power line 7 is formed, it is characterized in that electrothermal tube 3, is furnished with heating wire eduction rod 1, magnesia powder 2 is housed between electrothermal tube 3 and the heating wire, scribble insulator seal chewing-gum 4 in the electrothermal tube termination, heating wire eduction rod 1 is connected by copper pipe casting die 6 with power line 7, synthetic rubber 5 and electrothermal tube termination are placed in the pressing mold in the lump, are made for electrothermal tube termination seal by certain temperature and pressure.
