Description

The refrigerator tee union
Technical field
The utility model belongs to the refrigerator technical field, especially relates to a kind of refrigerator tee union.
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 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.In addition, Chinese patent literature also 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.
Above-mentioned two schemes has strengthened the practicability of existing tee union to a certain extent, and still, at least also there is following defect in this two schemes: design unreasonable, inconvenience is installed and when one of them joint damage, need to change whole tee union, cost is high, can't meet production requirement.
Summary of the invention
The purpose of this utility model is for the problems referred to above, and a kind of easy for installation and refrigerator tee union that cost is low is provided.
For achieving the above object, the utility model has adopted following technical proposal: this refrigerator tee union comprises the threeway body of being made by red copper, it is characterized in that, described threeway body comprises straight tube and the arm that is arranged on the straight tube sidepiece and communicates with straight tube, be respectively equipped with the first connecting head and the second connecting head at the two ends of straight tube, be provided with the first guide structure at the first connecting head away from an end of straight tube, be provided with the second guide structure at the second connecting head away from an end of straight tube, described straight tube is provided with the first stop part that is positioned at the first end of the first connection and is positioned at the second stop part of the first end of the second connection, described arm is connected with straight tube by removable structure.Obviously, the utility model design is more reasonable, structure is simpler, and Dao Re ﹑ ductility and corrosion resistance are good, is easy to install and location, virtually improved and part between connective stability, practical and long service life, in addition, its low cost of manufacture, can reduce maintenance cost, meet the development trend of current social technology.
In above-mentioned refrigerator tee union, described removable structure comprises the screw be arranged on straight tube, and described arm one end inserts in described screw and is threaded with screw.
In above-mentioned refrigerator tee union, described the first guide structure comprises the conical guiding sleeve that is arranged on the first end of the first connection; Described the second guide structure comprises the conical guiding sleeve that is arranged on the first end of the second connection.
In above-mentioned refrigerator tee union, described ring the first stop part comprises the first prevent surface be arranged on straight tube; Described the second stop part comprises the second prevent surface be arranged on straight tube.
In above-mentioned refrigerator tee union, described the first connecting head outer wall is provided with screw thread; Described the second connecting head outer wall is provided with screw thread; Described branch pipe wall is provided with screw thread.
In above-mentioned refrigerator tee union, described threeway body is in T shape.
Compared with prior art, this uses novel advantage to be: it is more reasonable to design, structure is simpler, and Dao Re ﹑ ductility and corrosion resistance are good, is easy to install and location, virtually improved and part between connective stability, practical and long service life, in addition, its low cost of manufacture, can reduce maintenance cost, meet the development trend of current social technology.
