Embodiment

Fig. 1 is the connection of existing sound detecting pipe and the schematic representation of seal arrangement.As shown in Figure 1, this device comprises fixedly screw socket 1, movable screw socket 2, Sealing, and in the present embodiment, the sealing part is a seal ring 3.As shown in Figure 1, existing connection and seal arrangement, the bottom surface of the ring-shaped platform that holds Sealing that is provided with in the fixing screw socket 1 and the joint of tubing termination 5 is concordant with tubing termination 5, the seal ring that adopts this form to place comes off when construction easily, when movable screw socket 2 screws, off normal easily, thereby influence airtight quality.

Fig. 2 and Fig. 3 are respectively embodiment's of the present utility model decomposition and assembling schematic representation.In conjunction with Fig. 2, shown in Figure 3, pipe end provided by the utility model connects and seal arrangement comprises that fixedly screw socket 1, movable screw socket 2, cross section are circular seal ring 3.One annular groove 6 that holds seal ring 3 is set in the joint of fixing screw socket 1 and tubing termination 5, and the bottom surface of this annular groove 6 is lower than tubing termination 5.Movable screw socket 2 is sleeved on the tubing 7, at the end tail of tubing 7 an annular horn mouth 4 is set, and the surface of contact of itself and seal ring 3 is curved surfaces.

When connecting tubing, seal ring 3 is put in the annular groove 6 of fixing screw socket 1, the annular horn mouth 4 of tubing 7 is pressed on the seal ring 3, with the fixing screw socket 1 of movable screw socket 2 screw-ins, make it compress seal ring 3 then.

Below in conjunction with Fig. 4 and Fig. 5 the foregoing description is described further.

Fig. 4 is the local enlarged diagram of the A of embodiment Fig. 2 of the present utility model, and wherein D represents the fixedly big footpath of screw socket 1, and the D1 representative is the path of screw socket 1 fixedly, and the P representative is the pitch of screw socket 1 fixedly, and h represents the degree of depth of annular groove 6, and d represents the outside diameter of tubing termination 5.

Fig. 5 is embodiment's seal ring 3 schematic representation of the present utility model.The cross section of sealing circle 3 is circular, and wherein H represents the height (being diameter) of seal ring 3, and M represents the race diameter of seal ring 3, and m represents the inner ring diameter of seal ring 3.

In order to guarantee that above-mentioned annular horn mouth 4 compresses seal ring 3 and don't can push up tubing termination 5, the degree of depth h of annular groove 6 must be less than the height H of seal ring 3, the degree of depth h that generally establishes annular groove 6 and the ratio h/H of the height H of seal ring 3 are 0.5～0.8, are preferably 0.5.

Be difficult for deviating from order to make seal ring 3 can put into annular groove 6 and be stuck in wherein, can make the pitch p of above-mentioned fixedly screw socket 1 be less than or equal to the height H of seal ring 3, the pitch p that generally establishes fixing screw socket 1 and the ratio p/H of the height H of seal ring 3 are 0.4～0.8, are preferably 0.5.And the path D1 of said fixing screw socket 1 should be less than the race diameter M of seal ring 3, and should fixedly the big footpath D of screw socket 1 should be greater than the race diameter M of seal ring 3, i.e. D1＜M＜D; And the inner ring diameter m of seal ring 3 should equal the outside diameter d of tubing termination 5.So just seal ring 3 can be enclosed within on the tubing termination 5, and the thread groove of the screw socket 1 that is fixed blocks, even with tubing termination 5 downwards or traverses, seal ring 3 can not drop out, this is very easily for site operation.When the movable screw socket 2 that is pressed on the seal ring 3 and is screwed when above-mentioned annular horn mouth 4 compressed, seal ring 3 can be squeezed and be full of annular groove 6 and thread groove, thereby reaches good sealing effect.

In a word, adopt the technical solution of the utility model to be used for the connection and the seal arrangement of circular pipe, not only good airproof performance, and easy construction is particularly suitable for being used as the connected element of sound detecting pipe.

It should be noted that at last: above embodiment is only unrestricted in order to technological scheme of the present invention to be described.Although the present invention is had been described in detail with reference to the foregoing description, those of ordinary skill in the art is to be understood that, still can make amendment and be equal to replacement technological scheme of the present invention, and not breaking away from the spirit and scope of the technical program, it all should be encompassed in the middle of the claim scope of the present invention.
