Background
The blocking and sealing performance in the pipeline is very important in operation, particularly in a well completion pipe column, the conveying medium in the pipeline causes pipeline corrosion and aging, the surface in the pipeline is rough, the rubber of the sealing and blocking tool is easy to cut open and damage, the service life of the rubber is seriously reduced, the pipeline sealing effect is also reduced, and if the pipeline is frequently maintained, the process is complex, the pipeline downtime is long, and time and labor are wasted.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an abnormal shape tapering sealing mechanism in pipeline has solved current pipeline shutoff intensity low, the poor problem of sealed effect.
The utility model provides an adopted technical scheme is, a heterotypic tapering sealing mechanism in pipeline, including connecting screw, cup joint the direction head on the connecting screw, direction head connection chuck, connecting screw passes the direction head near on the chuck, and the one end that the direction head is close to the chuck sets up the spout, and the chuck tip sets up and spout assorted slider, and spout and slider constitute the slip fork structure, and the slider surface sets up tapering inclined plane A, and tapering inclined plane A radially sets up sealed pad A, and the spout surface sets up tapering inclined plane B, and tapering inclined plane B radially sets up sealed pad B.
The utility model is also characterized in that,
and a spacer ring is arranged between the sealing gasket A and the sealing gasket B.
The middle part of the spacer ring is provided with a leakage hole.
A cavity is formed inside the connecting screw rod and the guide head, a spring is arranged on the outer wall of the connecting screw rod and is located inside the cavity, and a sealing rubber ring is arranged on the outer wall of the connecting screw rod.
And the sealing gasket A and the sealing gasket B are both O-shaped rubber sealing gaskets.
The beneficial effects of the utility model are that, an abnormal shape tapering sealing mechanism in pipeline, chuck and direction head constitute the slip fork structure, and when using, the slip fork structure compresses tightly sealed the pad, and sealed pad is at pipeline elasticity cover that rises, can sit the card at the optional position in the pipeline and seal, and the live time is long, and is effectual.

Fig. 1 is a schematic structural view of a special-shaped taper sealing mechanism in a pipeline of the present invention;
fig. 2 is a sectional view of the special-shaped taper sealing mechanism in the pipeline of the present invention.
In the figure, 1 is a clamping head, 2 is a sealing gasket A, 3 is a spacer ring, 4 is a sealing gasket B, 5 is a guide head, and 6 is a connecting screw rod.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model relates to an abnormal shape tapering sealing mechanism structure in pipeline, as shown in figure 1 and figure 2, including connecting screw rod 6, connecting screw rod 6 is last to cup joint direction head 5, direction head 5 connects chuck 1, connecting screw rod 6 passes direction head 5 near on chuck 1, direction head 5 is close to chuck 1's one end and sets up the spout, 1 tip of chuck sets up and spout assorted slider, spout and slider constitute the slide fork structure, the slider surface sets up tapering inclined plane A, tapering inclined plane A radially sets up sealed pad A2, the spout surface sets up tapering inclined plane B, tapering inclined plane B radially sets up sealed pad B4, sealed pad through with tapering inclined plane cooperation, make sealed pad outwards expand to open and then expand tightly fix at the pipe inner wall.
An interference seal is formed between the taper inclined plane A of the chuck 1 and the inner surface of the sealing gasket A2, another seal is formed between the taper inclined plane B of the guide head 5 and the sealing gasket B4, a spacer ring 3 is arranged between the sealing gasket A2 and the sealing gasket B4, the two groups of seals are separated by the spacer ring 3, the spacer ring 3 has a limiting and fixing function, a leakage hole is formed in the middle of the spacer ring 3, and emergency sealing is assisted when the sealing gasket A2 or the sealing gasket B4 is abnormally damaged.
A cavity is formed inside the connecting screw rod 6 and the guide head 5, a spring is arranged on the outer wall of the connecting screw rod 6, and the spring is positioned inside the cavity and used for providing resilience force for the connecting screw rod 6; and a sealing rubber ring is arranged on the outer wall of the connecting screw rod 6.
Both the gasket a2 and the gasket B4 were C-type rubber gaskets.
The utility model relates to a working principle of a special-shaped taper sealing mechanism in a pipeline; the displacement of the sliding fork of the chuck 1 and the guide head 5 is the elastic deformation generated when the sealing gasket A2 and the sealing gasket B4 are extruded, the sealing gasket A2 and the sealing gasket B4 increase the contact friction stress of the blocking structure and the inner wall of the pipeline, and the sealing performance is improved.
The utility model relates to a heterotypic tapering sealing mechanism's in pipeline working process: when the device is plugged, the device freely falls along an inner hole of a pipeline, the pressure in the pipeline is continuously increased, the connecting screw rod 6 extrudes the spring when being pulled, the guide head 5 is tightly pushed by a front end flange, the guide head 5 is pushed by the chuck 1 through a sliding fork structure formed by the chuck 1 and the guide head 5, and the continuous extrusion sealing gasket A2, the spacer ring 3 and the sealing gasket B4 are combined to realize reliable sealing plugging, so that the pipeline is effectively plugged.
The utility model has the advantages of simple structure and compact reasonable, direction head 5 and chuck 1 constitute the slip yoke structure, and the cohesion auto-lock, sealed pad receive the precompression and seal, and the leakproofness is fabulous, can sit the card at the optional position in the pipeline sealed, and the pressure is effectual in the sealed oil pipe, greatly increased block structure's sealed life-span.
