Embedded with lid end sealing ring 28.
Valve thimble 25 from left to right successively includes needle tip 25l, light bar segment 252, linkage section 253, seal section 254 and tail
End 255, wherein the left end of valve thimble 25 is arranged in needle tip 25l, and needle tip 25l is extend at refrigerant tank interface 22l,
The aluminium layer at the tank mouth of refrigerant tank l is punctured realization and opens at this time, and the aperture at the corresponding needle tip 25l of valve through holes 225 is big
In the diameter of needle tip 25l, refrigerant is enable to be passed into delivery outlet 231 from valve through holes 225；Light bar segment 252 has limit
Effect, when needle tip 251 is at refrigerant tank interface 221, the hole wall of the left end bearing against valve through-hole 225 of light bar segment 252,
Prevent needle tip 251 from moving on；253 diameter of linkage section is greater than the diameter of light bar segment 252, and the right end of linkage section 253, which is equipped with, to be used
In the external screw thread being threadedly coupled with valve body 22, correspondingly, corresponding to the work being threadedly coupled with linkage section 253 in valve through holes 225
Internal screw thread is equipped in dynamic stroke；The diameter of seal section 254 and the aperture of lid end 242 are adapted, and cover seal section 254 corresponding
It holds and forms sealing at sealing ring 28；The right end of valve thimble 25 is arranged in tail end 255, and tail end 255 is inserted into valve handle 26
Form tight fit.
It should be noted that since existing refrigerant opening valve is equipped with sealing structure, sealing knot usually at sealing
Structure be sealing ring is arranged on seal section 254, one end of sealing ring is extend into valve through holes 225, sealing ring it is another
22 end face of valve body is arrived on end top, and sealing ring, which is arranged on seal section 254, is easy sliding, therefore by using capping 24 by sealing ring
Fixing seal is on valve body 22, but the sealing structure only has once sealing, and sealing effect is bad, and capping 24 is screw thread company
It connects, capping 24 is easy to happen loosening, and when loosening, sealing ring can then loosen, then influences sealing effect.If sealing ring is embedding
Enter onto seal section 254, then will affect the screw thread setting of linkage section 253 and the screw thread setting of entire valve through holes 225, influence
Movement of the valve thimble 25 in valve body 22 is unreasonable.
In the present embodiment, by being equipped with lid end sealing ring 28, at this time lid end sealing ring 28 in the lid end 242 of capping 24
For stationary state, lid end sealing ring 28 is not moved in valve body 22 by entire valve thimble 25 to be influenced, without to valve top
The structure of needle 25, which is made, to be changed, and only needs capping 24 that the seal section 254 that lid end sealing ring 28 is used to adapt to valve thimble 25 is arranged, when
When seal section 254 is through lid end 242, lid end sealing ring 28 forms seal section 254 and seals, and refrigerant is not easy from lid at this time
It is leaked out in the through-hole of end 242；Further, to reinforce sealing effect, sealing joint circle is equipped on blocking interface 223
27, sealing is realized by capping 24 and the cooperation for blocking interface 223, then can prevent refrigerant from closure interface 223 and block
It is overflowed in the junction of lid 24.
Before carrying out opening refrigerant tank 1, the needle tip 251 of valve thimble 25 falls back on the right end of refrigerant tank interface 221,
Aluminium layer at the tank mouth of refrigerant tank 1 is intact sealing state.When needing to open refrigerant tank, the refrigerant tank of opening valve is connect
Mouth 221 is threadedly coupled with the external screw joint at the tank mouth of refrigerant tank 1, and nut set 21 is toward close to screw thread rotation at refrigerant tanks 1
Turn, until nut set 21 is tightened, entire opening valve is not easy to loosen and forms sealing at tank mouth at this time, then passes through rotary valve
Valve thimble 25 is screwed into valve body 22 by door handwheel 26, until the hole wall of the top of light bar segment 252 to valve through holes 225 limits, then
Needle tip 251 is screwed at refrigerant tank interface 221, and needle tip 251 pokes the aluminium layer at tank mouth during screw-in at this time,
Refrigerant tank 1 is opened.Due to needing that refrigerant is passed into efferent duct, then changeover valve handwheel 26 exits needle tip 251
Until valve through holes 225 are connected to delivery outlet 231 and refrigerant is made to circulate, pushed up when final valve thimble 25 is exited to linkage section 253
To capping 24 sealing 241 when valve thimble 25 be limited.
In the refrigerant process of circulation, refrigerant gasket seal 224 and nut set 21 sealing function under, be not easy from
It is leaked into the external world at tank mouth along nut set 21；Simultaneously as linkage section 253 is to be threadedly coupled with valve body 22, it is threadedly coupled tool
There is certain sealing function, refrigerant leakage rate weakens, and refrigerant divides two-way to leak, wherein connecing all the way through capping 24 with closure
The sealing function of the threaded connection of mouth 223 and the end face for blocking interface 223 compress, and subtract refrigerant leakage rate further
Weak, most afterwards through sealing joint circle 27 sealing, the leakage rate of refrigerant is by multi-layer sealed without leaking into the external world at this time, separately
Sealing is cooperatively formed by the through-hole of lid end sealing ring 28 and seal section 254 and lid end 242 all the way, is not easy refrigerant from envelope
It is leaked into the external world in blanking cover 24.
The foregoing is merely the better embodiment of the utility model, the utility model is not limited to above-mentioned embodiment party
Formula, there may be the structural modifications that part is small in implementation process, if various changes or modifications to the utility model are not
The spirit and scope of the utility model are detached from, and are belonged within the scope of the claims and equivalents of the utility model, then originally
Utility model is also intended to encompass these modification and variations.
