Abstract
The utility model belongs to the technical field of refrigerating devices, and particularly relates to a pipe joint for a refrigerating device. The pipe joint solves the technical problems that the available design is unreasonable and mounting is inconvenient. The pipe joint for the refrigerating device comprises a hollow joint body and is characterized in that the joint body is made of red copper and comprises a main body part; threads are formed in an inner wall of the main body part; a connecting part is arranged at one end of the main body part; an annular positioning part is arranged at the other end of the main body part; a guide structure is arranged at one end, away from the main body part, of the connecting part; a seal structure is arranged on the annular positioning part; and the outer diameter of the annular positioning part is greater than that of the connecting part. The pipe joint has the following advantages that the pipe joint is more reasonable in design, simpler in structure, good in heat conduction, good in ductility, good in corrosion resistance, easy to mount and position, and good in sealability; the connecting stability between the pipe joint and a spare part is improved virtually; the service life is prolonged virtually; and a development trend of the current social technology is met.
Description
Technical field
The utility model belongs to the refrigerator technical field, especially relates to a kind of for the refrigerator pipe joint.
Background technique
At the air-conditioning refrigeration system middle joint, it is a kind of important accessory; it be mainly used between tube and tube or pipe and equipment between be connected; in order to guarantee gas or liquid state in body, do not leak; joint must have sealing preferably, thereby but existing joint often can the phenomenon of leaking closely not occur owing to connecting when mounted.Except outside existing joint also exist: complex structure, inconvenience is installed, Applicable scope is little, intensity is low, the problems such as cost is higher, in refrigerator, it has the part of a lot of elbows, tee union and packing ring and so on, it is serving as indispensable key player tee union, can be used for the connection between several parts.In order to strengthen the practicability of tee union, for this reason, people have carried out long-term exploration, have proposed various solutions.
For example, Chinese patent literature discloses a kind of pipe coupling [application number: 97229150.4], and mainly by forming with externally threaded adapter body, gland nut, stuffing box gland, the adapter body internal surface is conical surface; Gland nut has internal thread; The stuffing box gland outer surface is conical surface, with the inner conical surface of adapter body, matches.In addition, Chinese patent literature also discloses a kind of conduit fast connection structure [application number: 200820060571.4], be included in the outer side surface moulding outside thread of a tubular body, one collar inner side surface moulding internal thread, the collar is with the external thread spiro fastening of internal thread and body, while making the relative body rotation of the collar, and the axial displacement that can make to overlap the hoop body, in the time of in water pipe is inserted in body, can be got loose to the location of water pipe by the axial displacement of the collar.
Above-mentioned two schemes has strengthened the practicability of existing pipe joint to a certain extent, and still, at least also there is following defect in this two schemes: design unreasonable, inconvenience is installed and install after exist and leak, can't meet usage requirement.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provide a kind of easy for installation and good airproof performance for the refrigerator pipe joint.
For achieving the above object, the utility model has adopted following technical proposal: this comprises for the refrigerator pipe joint joint body that is hollow, it is characterized in that, described joint body is made by red copper, this joint body comprises main part, inwall at main part is provided with screw thread, an end at main part is provided with joint, the other end is provided with circular orientation section, be provided with guide structure at joint away from an end of main part, be provided with sealing configuration in circular orientation section, the external diameter of described circular orientation section is greater than the external diameter of joint.Obviously, the utility model design is more reasonable, and structure is simpler, Dao Re ﹑ ductility and corrosion resistance are good, are easy to install and location, virtually improved and part between connective stability, good airproof performance, extended working life virtually, meets the development trend of current social technology.
Above-mentioned, for the refrigerator pipe joint, described sealing configuration comprises and is arranged on the annular seal groove of circular orientation section away from main part one end.
Above-mentioned, for the refrigerator pipe joint, described guide structure is circular cone.This structure can improve installation efficiency, the convenient installation.
Above-mentioned, for the refrigerator pipe joint, described joint outer wall is provided with screw thread.This structure is easily manufactured.
Above-mentioned, for the refrigerator pipe joint, described main part is hexagon.
Above-mentioned for the refrigerator pipe joint, described main part, joint and the circular orientation section formula that is connected as a single entity.
Compared with prior art, this uses novel advantage to be: it is more reasonable to design, structure is simpler, Dao Re ﹑ ductility and corrosion resistance are good, be easy to install and location, virtually improved and part between connective stability, good airproof performance, virtually extend working life, met the development trend of current social technology.
