Abstract

The utility model belongs to the technical field of refrigerating devices, and particularly relates to a two-way joint of a refrigerating system. The two-way joint solves the technical problems that the available design is unreasonable and the installation is inconvenient. The two-way joint of the refrigerating system comprises a joint body provided with a circulating channel, and is characterized in that the joint body is made of red copper and comprises a joint nut; a cylindrical body is arranged at one end of the joint nut; a tapered barrel provided with external threads is arranged at the other end of the joint nut; a separation prevention structure is arranged on the cylindrical body; and the length of the tapered barrel is at least four times that of the cylindrical body. The two-way joint has the following advantages that the two-way joint is more reasonable in design, simpler in structure, good in heat conduction, good in ductility, good in corrosion resistance and easy to mount and position; the connecting stability between the two-way joint and a part is improved virtually; the service life is prolonged virtually; and a development trend of the current social technology is met.

Description

Refrigeration system two pass joints
Technical field
The utility model belongs to the refrigerator technical field, especially relates to a kind of refrigeration system two pass joints.
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, two pass joints and packing ring and so on, it is serving as indispensable key player two pass joints, can be used for the connection between several parts.In order to strengthen the practicability of two pass joints, for this reason, people have carried out long-term exploration, have proposed various solutions.
For example, Chinese patent literature discloses a kind of abrasion-resistant pipe joint [application number: 201020202542.4], comprise housing, offer the first through hole and the second through hole on housing, the first connecting tube is installed in the first through hole, the second connecting tube is installed in the second through hole, and the first connecting tube and the second connecting tube are communicated with in enclosure interior, between the outer wall of the inwall of housing and the first connecting tube and the second connecting tube, wearing layer are set.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 easily loosening, the poor stability of tie point, 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 install after be difficult for loosening refrigeration system two pass joints.
For achieving the above object, the utility model has adopted following technical proposal: this refrigeration system two pass joints comprise the joint body with circulation passage, it is characterized in that, described joint body is made by red copper, this joint body comprises Female connector fittings, at an end of Female connector fittings, is provided with cylinder, and the other end is provided with has externally threaded conical shell, be provided with disconnecting prevention structure on cylinder, the length of described conical shell is at least four times of cylinder length.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, virtually extend working life, met the development trend of current social technology.
In above-mentioned refrigeration system two pass joints, described disconnecting prevention structure comprises the annular protrusion that is arranged on the cylinder outer wall.
In above-mentioned refrigeration system two pass joints, described conical shell microcephaly holds external diameter to be greater than the external diameter of cylinder.
In above-mentioned refrigeration system two pass joints, described conical shell is provided with the annular slot to make way be positioned near Female connector fittings one end.
In above-mentioned refrigeration system two pass joints, described cylinder is provided with the first outer chamfering away from an end of Female connector fittings, and described conical shell is provided with the second outer chamfering away from an end of Female connector fittings.
In above-mentioned refrigeration system two pass joints, described Female connector fittings, cylinder and the conical shell 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, virtually extended working life, meet the development trend of current social technology.
The accompanying drawing explanation
Fig. 1 is the structural representation that the utility model provides.
In figure, joint body 1, Female connector fittings 11, cylinder 12, annular protrusion 12a, the first outer chamfering 12b, conical shell 13, outside thread 13a, annular slot to make way 13b, the second outer chamfering 13c.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, this refrigeration system two pass joints comprise the joint body 1 with circulation passage, optimized project, the joint body 1 is here made by red copper, this joint body 1 comprises Female connector fittings 11, an end at Female connector fittings 11 is provided with cylinder 12, the other end is provided with the conical shell 13 with outside thread 13a, the Female connector fittings 11 of the present embodiment, cylinder 12 and conical shell 13 formula that is connected as a single entity, be provided with disconnecting prevention structure on cylinder 12, the length of described conical shell 13 is at least four times of cylinder 12 length.Obviously, the present embodiment design is more reasonable, and 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, virtually extended working life, meet the development trend of current social technology.
