Disclosure of Invention

The utility model aims to solve the problems that a sealing gasket is extruded and oxidized between two flanges in a long-term use process, and ageing occurs, so that the sealing effect between two flange plates is poor, and leakage of transmission substances between two pipelines is caused.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

the mechanical connecting flange comprises a flange main body, wherein a sealing mechanism is arranged on the inner wall of the flange main body;

the sealing mechanism comprises a sealing ring and a through hole;

the outer wall of sealing washer is laminated mutually with flange main part inner wall, the top processing of sealing washer has the through-hole.

Preferably, the inner wall sliding joint of flange main part has the cardboard, the inner wall of through-hole and the looks joint of one side of cardboard, the inner wall processing of cardboard has the round hole.

Preferably, the inner wall of the round hole is sleeved with a bolt, and the inner wall of the flange main body is provided with a reserved hole.

Preferably, the inner wall of the preformed hole is sleeved with the outer wall of the bolt.

Preferably, the outer wall thread of the bolt is connected with a nut, and a pipeline is arranged in the flange main body.

The mechanical connecting flange provided by the utility model has the beneficial effects that: through with the inner wall joint back of sealing washer and flange main part, the flange main part is spacing to the sealing washer, with the inside joint of the one end and the through-hole of cardboard, lets the outside and the flange main part joint of joint, cardboard cooperation flange main part is fixed to the sealing washer, and the sealing washer is fixed in the inside of flange main part, can not receive the extrusion of flange main part to the ageing speed that has delayed the sealing washer makes the sealed effect between two ring flanges better, prevents that transmission material from having the problem of leaking between two pipelines.

FIG. 2 is an enlarged schematic view of the seal ring and the through hole in FIG. 1;

FIG. 3 is an enlarged schematic view of the card of FIG. 1;

fig. 4 is an enlarged schematic view of the bolt and nut of fig. 1.

In the figure: 1. the flange comprises a flange main body, 2, a sealing mechanism, 201, a sealing ring, 202, a through hole, 3, a clamping plate, 4, a round hole, 5, a bolt, 6, a nut, 7, a pipeline, 8 and a reserved hole.

Detailed Description

The utility model is further described below with reference to the accompanying drawings:

referring to fig. 1-4: the mechanical connecting flange comprises a flange main body 1, wherein a sealing mechanism 2 is arranged on the inner wall of the flange main body 1, the sealing mechanism 2 seals the two flange main bodies 1, the sealing mechanism 2 comprises a sealing ring 201 and a through hole 202, the outer wall of the sealing ring 201 is attached to the inner wall of the flange main body 1, the flange main body 1 is limited to the sealing ring 201, the top of the sealing ring 201 is provided with the through hole 202, the inner wall of the flange main body 1 is slidably clamped with a clamping plate 3, the flange main body 1 is limited to the clamping plate 3, the inner wall of the through hole 202 is clamped with one side of the clamping plate 3, the through hole 202 is limited to the clamping plate 3, a round hole 4 is machined in the inner wall of the clamping plate 3, a bolt 5 is sleeved on the inner wall of the round hole 4, a reserved hole 8 is sleeved on the outer wall of the bolt 5, the reserved hole 8 is limited to the bolt 5, a nut 6 is screwed on the outer wall of the bolt 5, a pipeline 7 is arranged in the flange main body 1, and the nut 6 is reinforced to the bolt 5;
