Description

A kind of fixing device for pipe

Technical field

The present invention relates to mechanical structure field, a kind of fixing device for pipe is provided especially.

Background technique

In some pressurized containers and equipment; often can relate to the drawing of rigid line of device interior, fixing and sealing; conventional lead-out mode is to fix a transfer tube 1 at housing 1; pipeline 1 in pressurized container or the equipment is connected on the transfer tube 1, realizes the sealing that is connected by transfer tube cover plate 1 and the sealing gasket 1 between the housing 1.Yet because the particularity that pipeline is produced, its dimensional accuracy is difficult to be well controlled, and therefore, the required precision that conventional pipeline is drawn and means of fixation is produced pipeline is very high, and often need in the pipeline installation process to correct shape, so greatly increased production cost.Therefore, need design a kind of connection and the means of fixation not high to pipeline production required precision, generation and installation to make things convenient for pipeline reduce production costs.Prior device is referring to Fig. 1.

Summary of the invention

The objective of the invention is generation and installation in order to make things convenient for pipeline, the spy provides a kind of fixing device for pipe.

The invention provides a kind of fixing device for pipe, it is characterized in that: described fixing device for pipe comprises transfer tube 6, gland nut 7, cover plate 8, sealing gasket 9, housing 10;

Wherein: wherein be processed with screw thread on the transfer tube 6, match with gland nut 7, transfer tube 6 connects together with pipeline 11, gland nut 7 is threaded with transfer tube 6, until gland nut 7 contacts with sealing gasket 9, cover plate 8 is pressed on the gland nut 7, by bolt cover plate 8 is connected with housing 10.Owing to can radially adjust by screw thread at gland nut 7 and the relative position of transfer tube 6, and there is larger gap between gland nut 7 and the cover plate 8, can guarantee that gland nut 7 axially and perpendicular to the direction of paper is having enough dimension compensation amounts, thereby reduced the dimension precision requirement to pipeline processing, make things convenient for production and the installation of pipeline, reduced cost of production.

Have the gap between cover plate 8 and sealing gasket 9 or the housing 10, can fix gland nut 7 to guarantee cover plate 8 by bolt, the circular gap between gland nut 7 and the cover plate 8 is enough large, to ensure enough free sizes.Reach L4 and the L5 long enough of transfer tube 6 and gland nut 7 cooperation places are to ensure enough radial compensation sizes.

On the described gland nut 7 with flange A.

On the described cover plate 8, with a recess B and hole C.

The thickness L1 of described gland nut 7 upper flange A is greater than the degree of depth L2 of recess B on the cover plate, and the diameter B of outer rim A is less than the diameter C of recess B on the cover plate on the gland nut 7.

There is gap L 3 between described gland nut 7 and the hole C.

Advantage of the present invention:

Fixing device for pipe of the present invention is used for the structure that the pipeline on pressurized container or the equipment is drawn, and is applicable to the not high connection of pipeline production required precision and fixing, has made things convenient for production and the installation of pipeline, reduces production costs.

Description of drawings

The present invention is further detailed explanation below in conjunction with drawings and the embodiments:

Fig. 1 draws and the means of fixation schematic diagram for conventional pipeline;

Fig. 2 is that pipeline of the present invention is drawn and the means of fixation schematic diagram;

Fig. 3 is that pipeline of the present invention is drawn and the means of fixation partial view.
