Abstract
The invention belongs to the field of the metal pipe joint sealing devices and relates to a pipe joint sealing device comprising a semi-circle sleeve, a rubber pad, an outer sheath, an inner sheath, and a plug, wherein the inner side of the semi-circle sleeve is in contact with the outer side of the pipe joint, and one end of the semi-circle sleeve is provided with an inward boss; and the boss is buckled in a groove at one end of the inner sheath, the outer side and the inner side of the inner sheath are all provided with screw threads in design. The semi-circle sleeve and the inner sheath are screwed into the outer sheath. The middle part inside the outer sheath is provided with a screw thread, and the two ends of the screw thread are provided with light holes in design. The light holes are matched with the outer diameter of the semi-circle sleeve so as to ensure that semi-circle sleeve is buckled in the groove of the inner sheath all the time. The rubber pad is placed in the pipe joint. The plug is screwed into the inner sheath, so that the rubber pad is tightly pressed by one end of the plug to accomplish the sealing of the pipe joint.
Description
Technical field
The invention belongs to metallic pipe coupling seal arrangement field.
Background technique
Existing metal tube often is connected with pipe joint by the mode of welding, for the sealing of testing tube joint and metal tube solder joint or will block with the metal tube of pipe joint, seal the metal tube pipe joint.
The sealing of existing pipe joint generally all utilizes parts such as flange plate, rubber pad, bolt, nut, pressing plate to make up and seals, as shown in Figure 3.Existing pipe seal device needs the shape of pressing plate and flange plate consistent with pipe joint, and pipe joint needs bigger intensity pressing plate and flange plate institute applied pressure when satisfying sealing.If it is more special to run into the structure of pipe joint, utilize existing method to seal the purpose that often can not reach sealing during the relatively poor pipe joint of the intensity of self, also pipe joint may be damaged simultaneously.
Summary of the invention
The objective of the invention is:
Used pipe seal device when the objective of the invention is to design a kind of pipe seal can effectively seal pipe joint.
Technological scheme of the present invention is:
A kind of pipe seal device is made up of semicircle cover 1, rubber pad 2, overcoat 3, interior cover 4 and stifled 5;
All there is screw thread the outside and the inside of interior cover 4, and overcoat 3 bosoms partly are provided with screw thread, and overcoat 3 passes through the matching thread rotation set of interior cover 4 outsides and overcoat 3 inside outside semicircle cover 1 and interior cover 4;
The design of the two ends of overcoat 3 bosom part screw threads has unthreaded hole 10, and unthreaded hole 10 matches with the external diameter of semicircle cover 1, and guarantees that semicircle cover 1 is all the time in the groove 8 of button and interior cover 4;
Stifled 5 outside has screw thread, by screw-thread fit, blocks up the rubber pad 2 that an end of 5 compresses the inside that is placed on pipe joint between stifled 5 outside and interior cover 4 inside, makes rubber pad 2 finish sealing to pipe joint.
Advantage of the present invention is:
This pipe seal device can effectively seal the pipe joint of different size, different structure, varying strength.
Description of drawings
Accompanying drawing 1 is the structural representation of this pipe seal device;
Accompanying drawing 2 is structural representations of stifled 5;
Accompanying drawing 3 is schematic diagram of sealing device of existing pipe joint;
Embodiment
A kind of pipe seal device is made up of semicircle cover 1, rubber pad 2, overcoat 3, interior cover 4 and stifled 5;
In cover 4 outside and inside screw thread is all arranged, overcoat 3 bosoms partly are provided with screw thread, the matching thread rotation set of overcoat 3 by outside of inner cover and overcoat 3 inside is outside semicircle cover 1 and interior cover;
The design of the two ends of overcoat 3 bosom part screw threads has unthreaded hole 10, and unthreaded hole 10 matches with the external diameter of semicircle cover 1, and guarantees that semicircle cover 1 is all the time in the groove 8 of button and interior cover;
Stifled 5 close metal tube one end is six square toes 11, uses when being used for the spanner turn, away from the design of metal tube one end lightening core 12 is arranged; Stifled 5 outside has screw thread, and by screw-thread fit, interior cover 4 is processed with flat 9, flat 9 away from metal tube one end and can uses spanner that interior cover is fixed when blocking up 5 turns between stifled 5 outside and the interior cover inside; An end of stifled 5 compresses the rubber pad of the inside that is placed on pipe joint, makes rubber pad finish pipe seal.
Use when of the present invention, earlier interior cover is enclosed within on the pipe joint, again two semicircles cover 1 is contacted with the pipe joint outer surface and snap onto by boss 7 and cooperating of groove 8 in put, again overcoat 3 rotation sets are overlapped outside 1 at interior cover and semicircle, at this moment, rubber pad 2 can be placed on the inside of pipe joint, will block up again 5 screw in in the cover 4, can compress rubber pad and finish pipe seal thereby be further rotated stifled 5.
