Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is described in further detail.It should be appreciated that this place is retouched
The specific embodiment stated is only to explain the present invention, not limiting the present invention.
As shown in Figure 1 and Figure 2, the present invention includes base 1, stainless steel tube for the sealing and connecting device of embedding flammable liquid
2nd, thread head 3, clamp nut 4 and PTFE tube 5.
Base 1 is standard component, for being connected with the ceramic pump on filling and sealing machine.
In one end inserted base 1 of stainless steel tube 2 and by being laser welded, the other end and the Laser Welding of thread head 3
It is connected together.During welding, positioned using locating dowel, make stainless steel tube 2 and thread head 3 concentric.
Thread head 3 is provided with a through hole 31 along axis, is interference fitted in its front end 32 insertion PTFE tube 5 and with it, its rear end
With external screw thread 33.
Clamp nut 4 is enclosed on outside PTFE tube and thread head, and both are locked.
As shown in figs. 3 a-3 c, because PTFE tube is harder, can be closely connected with thread head 3, screw thread of the present invention
First 3 front end external diameter is divided into three sections, and the external diameter of outermost section 34 is less than the internal diameter of PTFE tube, and its purpose is easy to insert thread head 3
In PTFE tube；The external diameter of interlude 35 is more than the internal diameter of PTFE tube, and the purpose is to thread head 3 is further tightly inserted into PTFE
In pipe；The most external diameter of inner segment 36 and the internal diameter of PTFE tube it is identical and with PTFE tube be interference fitted.
Because PTFE tube is harder, for ease of thread head 3 is inserted in PTFE tube, as illustrated, thread head front end of the present invention
Interlude 35 and outermost section 34 between be provided with a cone angle be less than 40 degree, length for 2mm cone section 351.
Because the external diameter of the interlude 35 of thread head 3 is more than the external diameter of most inner segment 36, in order that PTFE tube can be with screw thread
Head most inner segment 36 is preferably interference fitted, and a cone angle also is provided between interlude 35 of the present invention and most inner segment 36 less than 40 degree, length
Spend the cone section 352 for 0.5mm.
After PTFE tube is tightly enclosed on 3 front end of thread head, for further two are closely attached together, the present invention
A clamp nut 4 is cased with outside both again.
As shown in Fig. 4 A- Fig. 4 C, the outer surface of clamp nut 4 of the present invention is hexagon, its internal diameter and the thread segment of thread head 3
External diameter match, its inwall is provided with screw thread 41.
For PTFE tube is tightly enclosed on thread head, both are locked, in the specific embodiment of the invention, clamp nut
4 minimum diameter is slightly larger than the external diameter of PTFE tube, and after clamp nut 4 is locked with thread head 3, both working face gaps are less than
The wall thickness of PTFE tube.After PTFE tube is locked, i.e., it is squeezed in securely in device, is not easy to collapse de-.
The present invention can be arranged between ceramic pump and filling and sealing machine blow tank punch block, and during installation, base 1 first is inserted into connecing for ceramic pump
Intraoral, interface is placed with PTFE seal circle, puts the original-pack locker locking of ceramic pump；One end of PTFE tube is put into pressure again
Tight nut, towards PTFE tube end face, screw thread is inserted in the one end that will be cased with the PTFE tube of nut in the direction of the internal thread of clamp nut
Head front end, reaches the root of front end, last locking nut and thread head, and PTFE tube is securely fixed；Then, tank pin will be blown
The other end of syringe needle insertion PTFE tube on frame.PTFE tube and the interference fit and thread head and nut pair of thread head front end
The extruding of PTFE tube causes the requirement for being connected up to sealing.
In addition, because the space in filling and sealing machine is limited, component is more, and the gap of inter-module is smaller, and what the present invention used
PTFE tube is harder, not pliable, to avoid PTFE tube from being interfered with other assemblies and safety door, disturbs the work of other assemblies
Make, as shown in Fig. 5 A- Fig. 5 C, the stainless steel tube 5 for forming the present invention is a radian pipe, in use, this can be arranged as required to
The installation site of invention.
Fig. 6, Fig. 7 are another embodiment of the present invention structural representation.When the present invention is used to connect filling and sealing machine ceramic pump with delaying
When rushing tank, present invention additionally comprises a chuck 6, stainless steel tube 2, a set of thread head 3 and clamp nut 4.
Chuck 6 is a standard component, and for connecting the surge tank of filling and sealing machine, it is directly fixed on the interface of surge tank.
One end of stainless steel tube 2 welds together with chuck 6, and the other end welds together with thread head 3.
The other end of PTFE tube is enclosed on outside thread head front end, and clamp nut is by the PTFE tube to link together and thread head
Locking.
Signified flammable liquid is the liquid that flash-point is not higher than 93 DEG C in the present invention.
In present pre-ferred embodiments, the flammable liquid includes methyl methacrylate, alcohol.
Advantages of the present invention：
1st, PTFE tube and thread head sealed connection of the present invention and firm and reliable connection, whole attachment means and ceramic pump, delay
Rush tank to be tightly connected reliably, in the absence of the phenomenon of leakage, and PTFE tube is corrosion-resistant, anti-oxidant, chemistry does not occur with any material
Reaction, therefore the present invention is pollution-free to liquid, service life length, so as to ensure that the security of flammable liquid embedding.
2nd, base, chuck and the stainless steel tube for forming the present invention weld together completely, during welding, by base, chuck set
Outside stainless steel tube, mutual bonding strength had both been ensure that, has reduced the connecting sewing of pipeline connection again.
3rd, the stainless steel tube for forming the present invention is angled, and using small space limited on filling and sealing machine, is realized
Surge tank and ceramic pump, ceramic pump and the connection for blowing tank punch block.
4th, PTFE tube and thread head interference fit of the present invention, for ease of making thread head insert in harder PTFE tube, this hair
The bright cone section of interlude design one in thread head front end, make the installation and removal of PTFE tube more laborsaving.
Above is the further description done to structure of the present invention.To those skilled in the art, do not carrying on the back
To any obvious change that it is done on the premise of from true spirit, will all form to patent right of the present invention
Invade, corresponding legal liabilities will be undertaken.
