Description
Technical field
The utility model relates to pressure pipeline apparatus fields, and in particular to a kind of self-sealing flange.
Background technique
High pressure self-locking type flange is a kind of to be more conducive to pipeline under the operating conditions harsh conditions such as high pressure, high temperature, high corrosion and connect
Novel high-pressure flange, and the core of high pressure self-locking type flange is exclusive new-type sealing, that is, relies on sealing lip (the T shape of sealing ring
Arm) flexible deformation formed sealing, belong to hard sealing, be pressurized when, muscle and lip play intensity and sealing respectively, can from
Close envelope, and pipeline can be reinforced, greatly strengthen the integral strength of connecting portion.
But after repeated multiple times use, once there is leakage situation in high pressure self-locking type flange, and existing leak stopping mode is not
It is applicable in, and the utility model is exactly to be improved on the basis of existing high pressure self-locking type flange, so that there are leakage feelings in it
It, being capable of timely injecting glue leak stopping when condition.
Utility model content
The utility model proposes a kind of self-sealing flange for the problems in above-mentioned background technique of effective solution, tool
Body technique scheme is as follows:
A kind of self-sealing flange, the card blue (2) being cooperatively connected including the set section (1) being arranged in pairs and the set section (1),
Ball-type nut (3) and bolt (4)；It further include T-type sealing ring (5) of the setting between set section (1), the T of the T-type sealing ring (5)
Type portion side is equipped with groove (6), is equipped with hole for injecting glue (7) with the set section (1) of the groove (6) corresponding position, the T-type sealing
The other side in ring (5) T-type portion and set section (1) are fitted close；
Preferably, hole for injecting glue (7) the connection glue injection valve (8), the rubber injecting valve (8) are threadedly coupled with hole for injecting glue (7), institute
Rubber injecting valve (8) are stated equipped with adjusting nut (9), valve body of the adjusting nut (9) perpendicular to rubber injecting valve (8)；
Compared with prior art, the utility model is had an advantage that: T-type sealing ring is transformed in the utility model,
So that the side in the T-type portion of T-type sealing ring opens up groove, certain cavity, the position of corresponding cavity are formed between groove and set section
Hole for injecting glue has been installed, when leaking, injecting glue processing has been carried out to groove by hole for injecting glue, ring packing cushion rubber is formed, plays
The effect of leak stopping, it is practical, and leakage crisis can be solved in time.

Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described
Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally
Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical
Novel protected range.
It is in the description of the present invention, it should be noted that term " center ", "upper", "lower", "left", "right", " perpendicular
Directly ", the orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only
For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific
Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.In addition, term " the
One ", " second ", " third " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.
A kind of self-sealing flange, including the set section 1 being arranged in pairs, the card orchid 2 being cooperatively connected with the set section 1, ball-type spiral shell
Mother 3 and bolt 4；It is characterized in that, further including the T-type sealing ring 5 being arranged between set section 1, the T-type portion one of the T-type sealing ring 5
Side is equipped with groove 6, is equipped with hole for injecting glue 7 with the set section 1 of 6 corresponding position of groove, the T-type portion of the T-type sealing ring 5 it is another
Side and set section 1 are fitted close；
The 7 connection glue injection valve 8 of hole for injecting glue, the rubber injecting valve 8 are threadedly coupled with hole for injecting glue 7, and the rubber injecting valve 8 is equipped with
Adjusting nut 9, valve body of the adjusting nut 9 perpendicular to rubber injecting valve 8；
Working method:
When there is leakage situation, glue injection equipment is connect by pipeline with rubber injecting valve, and opens adjusting nut, from hole for injecting glue to
Interior injecting glue, the annular space that is formed between unilateral groove and set section, is filled by injecting glue agent and seals, injecting glue agent in annular space,
The pressure-bearing pressure of flange is not will increase.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of utility model.
