Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing：
As shown in Fig. 2, which show the schematic diagrames of refrigerant according to the present utility model addition equipment.Refrigerant addition
Equipment includes cylinder connector 1 and air-conditioning connector 2, is connected between cylinder connector 1 and air-conditioning connector 2 by pipeline 3.Preferably, also
Three-way connector (not shown) can be equipped on pipeline 3.The first end connection cylinder connector 1 of three-way connector, second
End connection air-conditioning connector 2, third end are connected to air gauge, and the air gauge after injecting refrigerant for measuring the gas in air-conditioning
Pressure.Air-conditioning connector can be using in the prior art, such as Chinese patent application 2017206611915 and 2017206612424
Structure type is the ordinary skill in the art, and details are not described herein.
Cylinder connector 1 includes valve body 13, bonnet 12 and valve rod 11, and bonnet 12 is arranged in the upper end of valve body 13, in bonnet 12
Between be equipped with through-hole, the inner hollow of valve body 13 forms cavity, and valve rod 11 passes through the through-hole of bonnet 12 and the cavity of valve body 13, valve body
13 side, which is provided with, to be connected in the opening 17 with the opening 17 of its connects with the internal cavities, pipeline 3, thus by valve body
Portion is connected to pipeline 3.
As shown in figure 3, valve rod 11 includes the lever piece 111 set gradually, drive section 112, thread seal section 113, righting
The inner thread of section 114 and thimble section 14, thread seal section 113 and valve body 13 seals, and lever piece 111 is to be preferably provided with, can also
To be no longer arranged after doing a little adjustment as needed.The diameter of righting section 114 and the diameter of thimble section 14 are less than thread seal section
113 diameter, to form airflow channel between righting section 114 and valve body 13 and between thimble section 14 and valve body 13.Spiral shell
17 upside of opening of valve body 13 is arranged in line seal section 113, so that when valve rod 11 moves down, 113 energy of thread seal section
The lowest positions reached are still located on the upside of opening 17, thus will be between righting section 114 and valve body 13 and thimble section 14
Airflow channel between valve body 13 persistently keeps being connected to outlet 17.Preferably, lever piece 111 is threaded with operation knob
10；Sealing element 15 is equipped between bonnet 12 and valve body 13；O-ring seal is equipped between pipeline 3 and the opening 17 of valve body 13.Valve body
13 lower end is equipped with connector 19, is connected for the interconnecting piece with gas tank, it is preferred to use is threadedly coupled, is equipped in connector 19 close
Seal washer 18.
In order to guarantee that refrigerant can have enough spaces from gas tank through in airflow channel feed line, if righting section
Diameter is excessive, then it is relatively narrow to will lead to its airflow channel between valve body, to be unfavorable for the circulation of refrigerant.Advantageously, it helps
The diameter of positive section and the diameter ratio of body cavity are 0.8-0.9, and the diameter ratio of thimble section and body cavity is 0.4-0.6,
Rounding off section is equipped between righting section and thimble section.For example, the diameter of righting section is the body cavity of 4.3mm, corresponding position
Diameter be 5mm, the diameter of thimble section can be 2.5mm.The peripheral diameter of thread seal section is 6mm, peripheral diameter herein
Refer to the innermost diameter of screw thread.The diameter of righting section is smaller, around the airflow channel that is formed it is more clear and more coherent, but bring therewith
Problem is that the righting effect of righting section will be poorer.In order to improve righting effect, the diameter of righting section can be increased.For example, such as
Shown in Fig. 4, the diameter of righting section and the diameter ratio of body cavity can be 0.9-0.98, need the appearance in righting section at this time
Air channel 118 is arranged in face, in order to which refrigerant can be smoothly flowed out from air channel.
As shown in Fig. 2, in use, by the connector of 1 lower end of cylinder connector of the refrigerant addition equipment of the utility model
19 interconnecting pieces 92 for being connected to gas tank form sealing, and then driving stem moves down, and thimble section 14 opens gas tank as shown in Figure 1
Interface 93, so that the refrigerant in gas tank is passed through airflow channel, righting section and valve between interconnecting piece, thimble section and valve body
Opening, pipeline and the air-conditioning connector of airflow channel, valve body between body enter in air conditioning for automobiles.
In the second embodiment, thimble section 14 and righting section 114 can also be hollow structure, at this time righting section and top
The diameter of needle section can be set larger.In righting section 114, position corresponding with the opening of valve body is equipped with and above-mentioned hollow knot
The stomata 117 of structure connection, is arranged sealing element 116 between thimble section 14 and valve body 13.When hollow thimble is by the interface 93 of gas tank
When opening, the refrigerant in gas tank passes through interconnecting piece, thimble section, righting section, stomata, the opening of valve body, pipeline and air-conditioning connector
Into in air conditioning for automobiles.
Equipment is added using the refrigerant of the utility model, by the way that operation portion to be disposed over, to be provided with foot
Enough big operating spaces；When operating valve lever is downward, the interface of gas tank can not only be opened, but also can be connected to simultaneously gas tank and
Air-conditioning interface, to simplify operating procedure.
