And influence the normal use of user.
Summary of the invention
The purpose of this utility model is that: propose one kind can be realized online leak stopping, do not influence pipeline normally convey, user
The device of normal use.
In order to solve the above-mentioned technical problem, the utility model proposes technical solution be: one kind for gas pipeline insulate
The device for plugging of connector, including cylinder, pressure ring and sealing ring, the cylinder are made of two circular cylinder pairings and surround packet
The insulating joint is enclosed, two circular cylinders are connected by fastener；The both ends of the cylinder are equipped with the ring to extend internally
Shape end face baffle, respectively first baffle and second baffle, wherein the aperture of first baffle and the outer diameter of gas pipeline are consistent, the
The aperture of two baffles is greater than the outer diameter of gas pipeline, and the second baffle is bonded with the insulating joint outer wall of leakage side；It is described
Gap between second baffle and gas pipeline is equipped with sealing ring, and the pressure ring includes resisting the pressing ring of the sealing ring and setting
It sets in the one end of the pressing ring far from sealing ring and outwardly extending annular pressing plate, the pressure ring is by two semicircle pressure ring pairings
It constitutes, the annular pressing plate and second baffle are fixed together by junk ring bolt.
It preferably, further include the connecting plate for connecting two semicircle pressure rings, the connecting plate and two semicircle pressure rings are equal
It is affixed.
In order to guarantee cylinder and insulating joint essentially concentric when in use, the further improvement of above-mentioned technical proposal is: institute
State cylinder and be circumferentially at least three positioning screws along it, thus can by adjusting positioning screw come guarantee cylinder and insulation
Connector essentially concentric.
In order to be bonded second baffle completely with insulating joint outer wall, the further improvement of above-mentioned technical proposal
Be: the first baffle is equipped with adjusting screw, resists it outside other side of insulating joint by rotating adjusting screw in this way
Wall guarantees that second baffle is bonded completely with insulating joint outer wall.
The utility model at insulating joint leakage by will block, and bring is unfavorable when avoiding replacement insulating joint
It influences, realizes online leak stopping, normally conveyed and user's normal use to not influence pipeline.

Specific embodiment
Embodiment one
As shown in Figure 1, gas pipeline insulating joint 11 is for sealing two sections of gas pipelines 12.The present embodiment is used for combustion gas
The device for plugging of pipeline insulation joint, as shown in Figures 2 and 3, including cylinder 1, pressure ring 4 and sealing ring 10, the cylinder 1 is by two
A circular cylinder pairing, which is constituted and surround, surrounds the insulating joint 11, as shown in figure 3, two circular cylinders pass through bolt
7, nut 8 connects.
As shown in Fig. 2, the both ends of the cylinder 1 are equipped with the annular end face baffle to extend internally, respectively first baffle
13 and second baffle 14, wherein the aperture of first baffle 13 is consistent with the outer diameter of gas pipeline 12, and the aperture of second baffle 14 is big
In the outer diameter of gas pipeline 12, the second baffle 12 is bonded with 11 outer wall of insulating joint of leakage side.
Gap between the second baffle 14 and gas pipeline 11 is equipped with sealing ring 10, and the pressure ring 4 includes resisting institute
It states the pressing ring of sealing ring and the one end of the pressing ring far from sealing ring and outwardly extending annular pressing plate, the pressure ring is set
4 are made of two semicircle pressure ring pairings, and the annular pressing plate is fixed together with second baffle 14 by junk ring bolt 5.
Preferably, as shown in figure 3, two semicircle pressure rings are connected by connecting plate 6, the connecting plate 6 and two semicircles
It is affixed that shape pressure ring passes through screw.
The present embodiment can also make following improve:
1) first baffle 13 is equipped with adjusting screw 3, so that it is resisted insulating joint by rotating adjusting screw 3 in this way
