Abstract
The utility model relates to a connecting valve for a split air conditioner. One side of each of two connecting pipes of the valve is provided with an inner conical surface, and the other side is provided with a convex spherical surface. The convex spherical surface is matched and connected with the inner conical surface in a wire contact mode by a nut. The utility model is characterized in that the maximum outer diameter of the convex spherical surface is more than the inner diameter of a pipe of the inner conical surface and is less than or equal to the outer diameter of the pipe of the inner conical surface, which leads the nut to be directly fastened with a sphere body of the convex spherical surface to lead the two pipes to be connected. The production efficiency can be enhanced, and products are more reliable.
Description
The utility model be one with the valve that is connected of split-type air conditioner machine.
In the split-type air conditioner unit room of prior art, the connection valve of outer machine pipe such as accompanying drawing 1, among the figure: externally connected pipe 1, union nut 2, inner connecting tube 3, copper pipe 4, inner connecting tube 3 upper cap nut fixing lug boss 5, union nut 2 fastening boss 5, and in fixing, externally connected pipe, current boss 5 two kinds of manufacture methodes are arranged: 1. be to be welded on the inner connecting tube 3, production process complexity, and easily produce the phenomenon that gets loose, when particularly repeating to install and use, 2. be to produce, just need many one procedure man-hour adding like this with inner connecting tube 3 one, and when tightening up nut 2, the bad control of strength, strength is big also can be broken boss 5.
The purpose of this utility model provides a kind of not fragile, and the split-type air conditioner machine that can reliably repeatedly install and remove connects valve.
The technical solution of the utility model is such: the split-type air conditioner machine connects valve externally connected pipe, inner connecting tube, inside and outside adapter is protruding sphere on one side, another side is an inner conical surface, and inner cone facial canal outer rim has screw thread, in a union nut connects, externally connected pipe, protruding sphere is connected with inner cone upper thread contact matching, it is characterized in that: protruding sphere spheroid maximum outside diameter is greater than the internal diameter of inner cone facial canal, and smaller or equal to the external diameter of inner cone facial canal.
The utility model has the advantages that: 1, producing the time eliminates one step from the process, enhance productivity, and 2, eliminate the hidden danger that boss gets loose or ruptures, product is more reliable.
Further specify the utility model below by accompanying drawing.
Accompanying drawing 1, the structural drawing of the connection valve of prior art;
Accompanying drawing 2, the structural drawing of the utility model sphere valve.
Among Fig. 2, externally connected pipe 1, union nut 2, inner connecting tube 3, copper pipe 4, inner connecting tube epirelief spheroid 6.Be designed to an inner conical surface in externally connected pipe 1 interface, the mouthpiece outer rim has screw thread, and inner connecting tube 3 jointing tip designs become protruding sphere to form a protruding spheroid 6, and protruding spheroid 6 maximum outside diameters are greater than the internal diameter of externally connected pipe 1, smaller or equal to the external diameter of externally connected pipe 1.During use, the protruding sphere of inner connecting tube 3 stretches in the inner conical surface of externally connected pipe 1, and union nut 2 is being detained the protruding spheroid 6 on the inner connecting tube 3, with thread engagement on the externally connected pipe 1, the automatic centering heart under the axial pressure of the nut 2 of protruding sphere and inner conical surface, and the sealing of line contact matching.
Claims (1)
1, a kind of connection valve of split-type air conditioner, it has externally connected pipe, inner connecting tube, inside and outside adapter is protruding sphere on one side, another side is an inner conical surface, inner cone facial canal outer rim has screw thread, one union nut connects inside and outside adapter makes protruding sphere be connected with inner cone upper thread contact matching, it is characterized in that: protruding sphere spheroid maximum outside diameter is greater than the internal diameter of inner cone facial canal and smaller or equal to the external diameter of inner cone facial canal.
