The specific embodiment

Fig. 1 illustrates total Connection Element of 1 that is designated as, and this Connection Element 1 is positioned on the valve 2 that schematically illustrates.Connection Element 1 comprises a feed pipe 3 that is positioned on the valve, and this pipe comprises a thickening 4, and the outside face of thickening 4 is ball-shapeds.This thickening 4 can form the part of a separation, but preferably forms one unit with feed pipe 3.A gargle pipe 5 has been set to be connected with feed pipe 3.The internal diameter of gargle pipe 5 is more smaller than the external diameter of the ball of thickening 4.This causes one or two part that little distortion is arranged, thereby forms good sealing between feed pipe 3 and gargle pipe 5.Deformation rate depends on the material that corresponding part is used.The columnar combination of the sphere of thickening and gargle pipe 5 allows the angle between feed pipe 3 and the gargle pipe 5 to change in keeping the leak free certain limit.This is shown in Figure 2.

This causes the combination of good leak free cylinder and part spheroid also can differently be shaped.Figure 1B is illustrated in the combination that free end comprises such feed pipe 3 of a flange 6.The edge of flange 6 is columnar.The downside of feed pipe 5 comprises an interior thickening, thereby has spherical cavity.The diameter of flange 6 is set near the interior thickening that makes flange 6 and the contact surface for and is produced the sealing of certain deformation rate to obtain.

Fig. 1 C illustrates a structure, and wherein gargle pipe 5 extends in feed pipe 3.Here thickening is on gargle pipe 5.

Fig. 1 D illustrates a structure, and wherein as Fig. 1 C, gargle pipe 5 extends in feed pipe 3.Here, as Figure 1B, spherical surface is made spill.This spherical surface is directly arranged on the outside face of gargle pipe 5, and cylinderical surface is shaped on inside face.

The structure that it should be noted that the dribbling shape mating surfaces shown in Figure 1A and 1B has the angular turn between the axle that does not allow feed pipe and gargle pipe and allows vertically the advantage that moves mutually, and this is impossible in the structure of Figure 1B and 1C.

The application of this Connection Element of imagination now is a container of liquid, wherein provides propelling gas to be used to advance liquid in container.In order to keep container to seal, use a kind of valve, this valve is opened with the sideway movement of feed pipe 3.This structure illustrates at Fig. 3.This illustrates a columnar substantially container, and the shell of this container is designated as 10.The opposite of container is sealed by lid 11, and valve 2 is put into and covered in 11.Feed pipe 3 extends through from valve 2 and is located at the hole of covering 11.Feed pipe is made by plastics (for example polyformaldehyde (polyoxymethyleen)).The upside of feed pipe 3 comprises a thickening, and the outside face of thickening forms a sphere.3 one-tenth one units of this thickening and feed pipe.

One ring 13 has been arranged on around the thickening 3, and the inside face of ring 13 forms a cylindrical shape.Thickening interior through a little littler than the ball size of spherical thickening 3.This ring 13 contacts with spherical thickening 3, thereby has produced a small amount of distortion and improved sealing.Pin connection (form locking connection) by means of profiling, ring 13 forms the part with lid 15 bonded assembly parts 14.Lid 15 is suitable for letdown tank that liquid conductive is made to flexible material 16.Clearly visible as Fig. 3, by two material bridge 17, cover be located at shell of tank on ring be connected.The theme of the Netherlands patent applications 1029646 that this structure is still conflicted.

Material bridge 17 allows to wind by a path of material bridge 17 faces that determine and that extend into Fig. 4 tilt cover 15.This tilting action allows to cover 15 with the part 17 limited angle that tilts.This inclination makes the spherical thickening motion of ring 14 and feed pipe.Therefore feed pipe will turn over an angle, make valve open.When turning back to the initial position, valve 2 cuts out again at lid 15, because part 14 and lid 13 are parts of valve, and connected feed pipe 3 moves and returns its initial position.

When the existence of spherical thickening 4 also guarantees to carry out activity, good sealing between the feed pipe 3 of valve and the ring 13.In fact sealing is most important, because under those situations, flow of liquid is crossed valve 2.In addition, this structure allows the transmission for the no gap (playfree) of the power between ring 13 that plays the gargle pipe effect and feed pipe 3 of opening valve necessity.
