Abstract
The utility model relates to a tube joint and discloses a capillary tube joint easy to disassemble. The capillary tube joint comprises studs, seal compression rings and thread joints. The studs are connected with the thread joints in a threaded manner, two ends of each seal compression ring are respectively connected with the studs and the thread joints, and a capillary tube sequentially penetrates through the thread joints, the seal compression rings and the studs. Mutually contact surfaces of the seal compression rings and the studs are respectively conical surfaces matched structurally, after the seriously deformed seal compression rings are clamped with the thread joints in an attached manner, the capillary tube joint is quite easy to disassemble due to a combined design structure. By the aid of the capillary tube seal joint, only contact surfaces of the studs and the seal compression rings and contact surfaces of the seal compression rings and the capillary tube are required to be sealed, jacking force required for completing sealing is small, and when in use, the capillary tube joint is small in compressional deformation to the seal compression rings, small in seal compression ring damage and favorable for repeated use, and has a function of preventing the compression rings from clamping with other components.
Description
Technical field
The utility model relates to a kind of pipe joint, particularly relates to a kind of easily-disassembled capillary tube connector.
Background technique
At present, existing capillary tube connector as shown in Figure 1, Figure 2 and Figure 3, this capillary tube connector from left to right successively by tack capillary tube connect use double-screw bolt 6, seal joint 7, nut 8 and the capillary tube 5 that bottom has taper hole form, one end of seal joint 7 is plane, be connected with the planar ends contact of double-screw bolt 6, its the other end is the little conical surface (cone angle <90 °), is connected with the conical surface end in contact of nut 8, and capillary tube 5 is successively through nut 8, seal joint 7 and double-screw bolt 6.
The advantage of above-mentioned capillary tube connector is that component are few.Its shortcoming is: because the fluid in capillary tube 5 can leak out with the plane that seal joint 7 contacts through double-screw bolt 6, therefore, one of them is plane for two sealing surfaces that need to seal, as being A face, B face in Fig. 3, A face is in the vertex of a cone place of seal joint 7, seals that required jacking force or pressure ring deformation are less can realize sealing; And be plane for making B face, for obtaining, make it seal required pressure ring deformation, required normal pressure will go out greatly much with respect to the required pressure of cone tip part conical surface seal, this can make seal joint 7 to bear and radial deformation occurs compared with pressure greatly, as shown in Figure 4 and Figure 5, if operator lacks experience, once the deformation surplus of seal joint 7 will be used to the greatest extent, the conical surface that causes seal joint 7 and nut 8 even part internal thread place, capillary tube 5 all blocks and clings, not easily-disassembled.
Because seal joint 7 and nut 8, capillary tube 5 all block and cling, when dismounting nut 8, apply a torsion can to capillary tube 5, be easy to make even fracture of capillary tube 5 damages.
Once seal joint 7 and nut 8 cards cling and are just difficult to complete separatedly again, and have to take out seal joint 7 is destructive, and cause waste.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
Embodiment one
As shown in Fig. 6,7 and 8, a kind of easily-disassembled capillary tube connector of the present utility model, it comprises double-screw bolt 1, seal joint 2 and inipple, double-screw bolt 1 and inipple are threaded, contact is connected with inipple with double-screw bolt 1 respectively at the two ends of seal joint 2, capillary tube 5 is successively through inipple, seal joint 2 and double-screw bolt 1, the surface that seal joint 2 and double-screw bolt 1 are in contact with one another is respectively the conical surface that structure matches, be that all to have an end face be the conical surface for seal joint 2 and double-screw bolt 1, these two cone structures match, and can realize face contact.
The surface that seal joint 2 contacts with double-screw bolt 1 is male cone (strobilus masculinus), and the surface that double-screw bolt 1 contacts with seal joint 2 is inner conical surface.
Because the surface that the fluid in capillary tube 5 can only contact with seal joint 2 through double-screw bolt 1 is permeated, therefore, the surface (D face) that the surface (C face) that only double-screw bolt 1 need to be contacted with seal joint 2 and seal joint 2 contact with capillary tube 5 seals, as shown in Figure 8, the surface that the utility model is in contact with one another seal joint 2 and double-screw bolt 1 is respectively the conical surface that structure matches, less jacking force can be applied and the seal action between seal joint 2 and double-screw bolt 1 can be realized, extrusion-deformation during use, seal joint 2 being caused is less, seal joint is impaired less, be easy to disassemble, be easy to be repeatedly used.
Due to, only need seal with the surface that seal joint 2 contacts double-screw bolt 1, therefore, one end that the utility model preferred embodiment seal joint 2 contacts with inipple can be made as plane, needn't be strict with the sealing between seal joint 2 and inipple again.But, it is pointed out that for dual sealing effect is provided, meanwhile, the conical surface that structure matches is arranged on the surface that also seal joint 2 and inipple can be in contact with one another.Preferably, seal joint 2 is made by graphite, is graphite pressure ring; Or seal joint 2 can also be made by the macromolecular material with certain deformability.
Inipple comprises nut 3 and screw 4, and one end of nut 3 is threaded with double-screw bolt 1, and its other end is threaded with screw 4, capillary tube 5 is through screw 4, the end of seal joint 2 is connected with screw 4 contacts, has increased screw 4, is in order to facilitate further the dismounting of seal joint 2.
Embodiment two
The present embodiment and embodiment's one difference is only, inipple is nut, and nut is threaded with double-screw bolt, has the structure that the end with seal joint matches in nut.Be specially, the inner contact of seal joint and nut is connected, and when the end face contacting with nut when seal joint is plane, the interior position accordingly of nut is also plane structure; When the end face contacting with nut when seal joint is the conical surface, in nut, corresponding position be also cone structure, and these two cone structures match, and the face of can realizing contacts.
A kind of easily-disassembled capillary tube connector that technique scheme provides, mainly has the following advantages:
1, the surface that seal joint contacts with double-screw bolt is set to the conical surface, only need C face and the D face of sealing, the extrusion-deformation that the required jacking force of sealing is less in order to complete, cause seal joint during use is little, and seal joint is impaired little, be easy to disassemble, be easy to be repeatedly used;
2, the seal joint that is designed to distortion of this adapter assembly has been reserved larger deformation space, makes the seal joint of distortion be difficult for sticking together with other connection part (double-screw bolt and inipple) card;
Even if together with the seal joint of 3 distortion has been bonded at other assembly card, can be easy to intact the dismantling of the seal joint of distortion by disassembling screw, the seal joint even removing may also can be used.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
