Pipe 300 includes that body 310 and two is separately positioned on the nut 320 at body 310 two ends, a spiral shell of this adapter 300
Female 320 are spirally connected with joint 217, and another nut 320 of this adapter 300 connects off-premises station or indoor set, thus room
The cold-producing medium of outer machine output is delivered to corresponding adjusting means 200 or from corresponding adjusting means through body 310
The cold-producing medium of 200 outputs carries indoor set through body 310.
Referring to figure Fig. 1, Figure 15 and Figure 16, capillary tube 100 has the portion that twists 110 He being coiled into by body
Two line parts 120 extended out from the portion of twisting 110, wherein the end of a line part 120 forms the first end
121, this first end 121 is entrance point, and the end of another line part 120 forms the second end 122, and this is second years old
End 122 is the port of export, and is respectively provided with the boss 123 of an annular at the first end 121 and the second end 122, accordingly
The diameter of boss 123 is more than the first end 121 or diameter of the second end 122 opening part.
First end 121 of capillary tube 100 and the second end 122 insert the drain pan 230 of two adjusting meanss 200 respectively
Mouthpiece 236 in and be weldingly fixed on mouthpiece 236, and boss 123 is connected to the end of mouthpiece 236
On edge, thus control the first end 121 and the second end 122 inserts the degree of depth of mouthpiece 236, to avoid insertion to connect
Mouthful pipe 236 cross deep and push up regulation valve 220 or shallow and cause not prison welding.
When using capillary tube device used for air-conditioning system refrigeration matching debugging of the present invention, stir adjusting knob
222 so that regulation valve 220 rotates around pivot 213, so that the first sealed end 225 and second of regulation valve 220
Sealed end 226 rotates respectively in upper cover seal groove 214 and drain pan seal groove 234, and then makes the first sealed end
225 and second sealed end 226 drive the first sealing gasket 240 to rotate in upper cover seal groove 214 and second respectively
Sealing gasket 250 rotates in drain pan seal groove 234；When rotating regulation valve 220, make passage 229 and second
One drain pan through hole 235 of the corresponding drain pan 230 of the perforate 253 of sealing gasket 250, so that passage 229 and a capillary
Pipe 100 connects；After passage 229 connects with a capillary tube 100, cold-producing medium is led from an adjusting means 200
Pipe 216 enters the first chamber 223 of regulation valve 220, enters the cold-producing medium in the first chamber 223 of this adjusting means 200
Entered by the perforate 253 of passage the 229, second sealing gasket 250 of this adjusting means 200, drain pan through hole 235
First end 121 of corresponding capillary tube 100, then cold-producing medium from the second end 122 of this capillary tube 100 through separately
The perforate 253 of drain pan through hole the 235, second sealing gasket 250 of one adjusting means 200, passage the 229, first chamber
223 conduits 216 entering this adjusting means 200, thus can when air conditioning system carries out freezing matching and debugging
To select one to carry out the matching and debugging that freezes from capillary tube 100 by rotation regulation valve 220.
Owing to capillary tube device used for air-conditioning system refrigeration matching debugging of the present invention is by rotating regulation valve
220 so that the passage 229 of regulation valve 220 connects with a drain pan through hole 235, thus in multiple capillary tubies 100
Select one to carry cold-producing medium and the matching and debugging that carries out freezing, and then carry out refrigeration coupling in air conditioning system
Unselected capillary tube 100 will not gather during debugging cold-producing medium, therefore carry out refrigeration coupling in air conditioning system
The accuracy of cooling parameters is improve during debugging.
Regulation valve 220 makes passage 229 and a drain pan through hole by the way of rotation the most in the present embodiment
235 connections can also convert position makes passage 229 connect with a drain pan through hole 235 by the way of moving left and right,
Particularly by upper cover seal groove 214 side of being designed to annular, thus make tune when regulating valve 220 and moving left and right
One end of the passage 229 of joint valve 220 connects with a drain pan through hole 235, and then by moving left and right regulation valve
220 select a capillary tube 100 to carry cold-producing medium, and make other capillary tube 100 be not involved in work and not
Cold-producing medium can be gathered.
These are only the preferred embodiments of the present invention, not thereby limit the scope of the claims of the present invention, every
Utilize equivalent structure or equivalence flow process conversion that description of the invention and accompanying drawing content made, or directly or
Connect and be used in other relevant technical fields, be the most in like manner included in the scope of patent protection of the present invention.
