Abstract
The utility model provides a refrigerant filling and plugging device. The refrigerant filling and plugging device comprises a refrigeration pipe loop, a refrigerant filling pipe, a pinching bit arranged on the refrigerant filling pipe, a seal core column inserted in the refrigerant filling pipe, a plug cap compressing the seal core column on the refrigerant filling pipe, and a clamp ring sleeved on the plug cap. After being filled, the refrigerant filling pipe can be flattened through pinching and is sealed through plugging up the tail end of the refrigerant filling pipe with the seal core column, compressing the seal core column through the plug cap, and finally compressing the refrigerant filling pipe, the plug cap and the seal core column through the clamp ring. The refrigerant filling and plugging device has the advantages of no need of hot work and good sealing performance.
Description
Technical field
The utility model belongs to the refrigeration appliance field, relates in particular to the refrigerant charging channel closure technology of field of air conditioning.
Background technology
In family expenses refrigerating appliance field, after vacuumizing, refrigeration system needs to fill cold-producing medium.The refrigerant charging pipe needs to carry out shutoff after refrigerating appliance fills cold-producing medium.Existing refrigerant charging pipe blocking technology is, and is with the Sealing pliers of twitching one's mouth that refrigerant charging pipe (material is a copper tube) folder is flat, and then with the high temperature gas welding with the shutoff of the filler line mouth of pipe.The high-temperature gas welding need be at welding on-the-spot deposit oxygen and acetylene and special welding gun.Because acetylene is inflammable and explosive hazardous gas, easy initiation fire.During high-temperature soldering refrigerant charging pipe, can heat the cold-producing medium in the refrigeration system, the clamping degree of Sealing pliers has inefficacy slightly if twitch one's mouth, just the cold-producing medium micro-leakage can take place, the words cold-producing medium that weld this moment can be resolved into toxic gas by high temperature sintering and damage the healthy of welder.Along with cold-producing mediums such as existing R22, R410A because of consuming the ozone in the atmosphere or greenhouse effects are excessive will be substituted by natural preparation (the R290 high-purity propane is a liquefied petroleum gas), and most natural cold-producing mediums all can not carry out construction operation with naked light, therefore a kind of plugging device of the refrigerant charging pipe without the naked light welding is provided, and real be necessity.
The utility model content
The purpose of this utility model is to provide a kind of refrigerant charging plugging device without work with torches, good seal performance.
Technical solutions of the utility model are:
A kind of refrigerant charging plugging device, it comprises refrigerator pipes loop, refrigerant charging pipe, the refrigerant charging pipe is provided with the flat position of folder, and it also comprises the sealing stem stem that is inserted in the refrigerant charging pipe, will seal stem stem is pressed in the blocking cap on the refrigerant charging pipe and is enclosed within hold-down ring on the blocking cap.
More specifically, described sealing stem stem is provided with annular boss.
More specifically, described annular boss is provided with groove, is arranged with O-ring seal on the groove.
More specifically, described hold-down ring is provided with twice and compresses the position, and when it is enclosed within when compressing on the blocking cap, corresponding twice compress distortion groove that bit position the produces both sides of annular boss on the sealing stem stem respectively on the refrigerant charging pipe.
The utility model fills the back by the flat refrigerant charging pipe of folder, and block refrigerant charging pipe end with the sealing stem stem, compress the sealing stem stem with blocking cap, the mode that compresses refrigerant charging pipe, blocking cap and sealing stem stem with hold-down ring realizes sealing at last, the utility model is without work with torches, good seal performance.
Description of drawings
Fig. 1 is the refrigerant charging plugging device schematic diagram of the utility model embodiment.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Referring to Fig. 1, in this preferred embodiment, this refrigerant charging plugging device comprises refrigerator pipes loop 1 and the refrigerant charging pipe 2 that is connected with refrigerator pipes loop 1, refrigerant charging pipe 2 is provided with the flat position 3 of folder, end is plugged with sealed core post 4 in refrigerant charging pipe 2 pipes, the part of inserting refrigerant charging pipe 2 at sealing stem stem 4 is provided with annular boss 5, offer groove 6 on the annular boss 5, its cross section semicircular in shape, be with circular O-ring seal 7 on the groove 6, the outer hollow cylindrical blocking cap 8 that is with an end opening of refrigerant charging pipe 2 terminal pipes, the openend external diameter of blocking cap 8 is bigger than sealing end external diameter, is with hold-down ring 9 on the blocking cap 8, and the front end of hold-down ring 9 is truncated cone-shaped of hollow, its internal diameter is littler than the external diameter of blocking cap 8, be provided with in addition on the hold-down ring 9 twice at a distance of certain distance compress the position 10.
The installation process of the utility model after refrigerant charging is finished is as follows: with sealing the flat position 3 of clamp folder, refrigerant charging pipe 2 folders are flat, then, sealing stem stem 4 is inserted in the end inlet of refrigerant charging pipe 2, O-ring seal 7 on the annular boss 5 is resisted against the inwall of refrigerant charging pipe 2, play sealing function, again blocking cap 8 is enclosed within the end of refrigerant charging pipe 2, hold-down ring 9 is enclosed within on the blocking cap 8, with the direction pulling hold-down ring 9 of instrument towards refrigerator pipes loop 1, hold-down ring 9 front ends are closely bound round on blocking cap 8, simultaneously under the pulling function of hold-down ring 9, the sealing end of blocking cap 8 abuts against on the sealing stem stem 4, the bottom of sealing stem stem 4 can be sealed the end of refrigerant charging pipe 2 again, blocking cap 8 with just formed sealing relationship by the refrigerant charging pipe 2 of shutoff and sealing stem stem 4, compress 10 with pneumatic round mouth crush inhury with twice again and compress this moment, makes hold-down ring 9, blocking cap 8 and by the refrigerant charging pipe 2 of shutoff deformation is taken place all and form twice distortion groove.The twice distortion groove that produces on the refrigerant charging pipe 2 lays respectively at the two ends of the annular boss 5 of sealing stem stem 4.The distortion groove is formed nested hold down gag with the annular boss 5 of sealing stem stem, has further guaranteed sealing function and the phenomenon of raising one's hat can not occur.The utility model is realized sealing to the refrigerant charging pipe by above structure, good seal performance not only, and do not adopt work with torches, the security performance height.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion.And all these improvement and conversion all should belong to the protection domain of the utility model claims.
