Description

A kind of flange seal metal Raschig ring

Technical field

The utility model relates to conduit coupling more particularly to a kind of flange seal metal Raschig rings.

Background technique

Flange is for connection to the connecting component of pipeline, after flanged joint, it is necessary to assure the leakproofness of junction, anti-stopping leak Dew, traditional connecting component is to connect 8 word blind plates between the flanges, and 8 word blind plates and flange directly also set up sealing, structure Complexity, centering trouble, installation trouble, and 8 word blind plates are easy to collide with flange when installation, cause sealing surface to damage, influence to seal Effect.

Utility model content

The applicant is directed to disadvantage mentioned above, has carried out Improvement, provides a kind of flange seal metal Raschig ring.

Technical solution used by the utility model is as follows:

A kind of flange seal metal Raschig ring, between the flanges, metal Raschig ring includes ring for the metal Raschig ring setting Body, the ring body inside open up through-hole, connection sealing bulge loop on ring body two sides, and ring body is located on the position on the outside of sealing bulge loop Several connection screw thread holes are uniformly opened up, the connection screw thread hole is consistent with the threaded hole aperture of flange, connection on the outside of the ring body Handle opens up connecting hole on the handle.

As a further improvement of the above technical scheme:

The through-hole includes the both ends horn mouth that diameter constantly increases from inside to outside and intermediate cylindrical section.

The ring body periphery is located remotely from handle side and opens up location hole, and the positioning hole is inserted with lifting button.

The sealing bulge loop includes straight wall section and contraction section, and straight wall section one end connects ring body surface, other end connection Contraction section, the section of the contraction section are trapezoidal.

The beneficial effects of the utility model are as follows: the flange seal metal Raschig ring, are arranged between the flanges, centering side Just, easy for installation, and it is not easy damaged in collision, prevent sealing performance impaired.

Detailed description of the invention

Fig. 1 is the cross-sectional view of the flange seal metal Raschig ring of the utility model.

In figure: 1, ring body；11, through-hole；111, horn mouth；112, cylindrical section；12, location hole；2, bulge loop is sealed；21, straight Wall section；22, contraction section；3, connection screw thread hole；4, handle；41, connecting hole；5, lifting button.

Specific embodiment

With reference to the accompanying drawing, illustrate the specific embodiment of the present embodiment

As shown in Figure 1, the flange seal metal Raschig ring of the present embodiment, metal Raschig ring is arranged between the flanges, metal Raschig ring includes ring body 1, and through-hole 11 is opened up on the inside of ring body 1, and through-hole 11 includes the both ends loudspeaker that diameter constantly increases from inside to outside Mouthfuls 111 and intermediate cylindrical section 112, connection sealing bulge loop 2 on 1 two sides of ring body, sealing bulge loop 2 includes straight wall section 21 and contraction section 22,21 one end of straight wall section connects 1 surface of ring body, and the other end connects contraction section 22, the section of contraction section 22 be it is trapezoidal, ring body 1 In uniformly opening up several connection screw thread holes 3, the threaded hole aperture of connection screw thread hole 3 and flange on the position in sealing bulge loop 2 outside Unanimously, handle 4 is connected on the outside of ring body 1, connecting hole 41 is opened up on handle 4, and 1 periphery of ring body, which is located remotely from 4 side of handle and opens up, determines Position hole 12 is inserted with lifting button 5 in location hole 12, facilitates flange seal metal Raschig ring handling.

The flange seal metal Raschig ring is in use, can drive the movement of metal Raschig ring, the method in side by handle 4 Connection bolt is put on the bolt hole in blue outside, and connects connection screw thread hole 3 of the bolt in ring body 1, metal is filled Circle navigates on a side flange, and the flange of the other side makes to connect bolt again through the flange of the other side close to metal Raschig ring In threaded hole, attaching nut is fixedly connected with two side flanges, and metal Raschig ring is connected between two flanges, cooperates ring body 1, sealing bulge loop 2 realizes the sealing of two side flanges.

Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model Range is referring to claim, and without prejudice to the basic structure of the utility model, the utility model can make any shape The modification of formula.
