Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is described in further detail.It should be appreciated that herein
Described specific embodiment is only to explain the utility model, not limiting the utility model.
As shown in Figure 1 and Figure 2, the utility model, which is used for the sealing and connecting device of embedding flammable liquid, includes base 1, stainless
Steel pipe 2, 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, the utility model
The front end external diameter of thread head 3 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 thread head 3
Insert in PTFE tube;The external diameter of interlude 35 is more than the internal diameter of PTFE tube, and the purpose is to be further tightly inserted into thread head 3
In PTFE tube;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, the utility model thread head
The cone section 351 that a cone angle is less than 40 degree, length is 2mm is provided between the interlude 35 and outermost section 34 of front end.
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 the utility model interlude 35 and most inner segment 36 less than 40
Degree, the cone section 352 that length is 0.5mm.
After PTFE tube is tightly enclosed on 3 front end of thread head, for further two are closely attached together, this practicality
It is new to be cased with a clamp nut 4 again outside both.
As shown in Fig. 4 A- Fig. 4 C, the outer surface of the utility model clamp nut 4 is hexagon, its internal diameter and the spiral shell of thread head 3
The external diameter of line section matches, and its inwall is provided with screw thread 41.
For PTFE tube is tightly enclosed on thread head, both are locked, in the utility model specific embodiment, compressed
The minimum diameter of nut 4 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 small
In 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 utility model can be arranged between ceramic pump and filling and sealing machine blow tank punch block, and during installation, base 1 first is inserted into ceramic pump
Interface in, interface is placed with PTFE seal circle, put ceramic pump it is original-pack locker locking;One end of PTFE tube is covered again
Upper clamp nut, the direction of the internal thread of clamp nut will be cased with one end insertion of the PTFE tube of nut towards PTFE tube end face
Thread head front end, reaches the root of front end, last locking nut and thread head, and PTFE tube is securely fixed;Then, will blow
The other end of syringe needle insertion PTFE tube on tank punch block.PTFE tube and the interference fit and thread head and nut of thread head front end
Extruding to 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 the utility model uses
PTFE tube it is harder, it is not pliable, to avoid PTFE tube from being interfered with other assemblies and safety door, disturb the work of other assemblies
Make, as shown in Fig. 5 A- Fig. 5 C, it is a radian pipe to form stainless steel tube 5 of the present utility model, in use, can set as needed
Put installation site of the present utility model.
Fig. 6, Fig. 7 are another example structure schematic diagram of the utility model.When the utility model is used to connect filling and sealing machine pottery
When porcelain pump is with surge tank, the utility model also includes 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 utility model.
In the utility model preferred embodiment, the flammable liquid includes methyl methacrylate, alcohol.
The advantages of the utility model:
1st, the utility model PTFE tube and thread head sealed connection and firm and reliable connection, whole attachment means and ceramics
Pump, surge tank are tightly connected reliably, and in the absence of the phenomenon of leakage, and PTFE tube is corrosion-resistant, anti-oxidant, are not occurred with any material
Chemical reaction, therefore the utility model is pollution-free to liquid, service life length, so as to ensure that the security of flammable liquid embedding.
2nd, form base, chuck and stainless steel tube of the present utility model completely to weld together, during welding, by base, card
Disk is enclosed on outside stainless steel tube, both ensure that mutual bonding strength, reduces the connecting sewing of pipeline connection again.
3rd, stainless steel tube of the present utility model is formed to be angled, using small space limited on filling and sealing machine,
Realize surge tank and ceramic pump, ceramic pump and the connection for blowing tank punch block.
4th, the utility model PTFE tube and thread head are interference fitted, for ease of making thread head insert in harder PTFE tube,
Section is bored in interlude design one of the utility model in thread head front end, makes the installation and removal of PTFE tube more laborsaving.
Above is the further description done to the utility model structure.To those skilled in the art, exist
To any obvious change that it is done on the premise of without departing substantially from the utility model in essence spirit, will all form to this practicality
The infringement of new patent power, will undertake corresponding legal liabilities.
