Abstract
The utility model relates to a rapid plug which comprises a bolt. The bolt comprises a hexagonal head and a screw rod integrated with the hexagonal head, a baffle plate is fixedly connected at the top end of the screw rod, a movable nut, a first pressing plate, a sealing ring and a second pressing plate are sequentially arranged from the baffle plate to the hexagonal head, and the sealing ring is made of rubber materials. The rapid plug is sealed in an expanding and pressing manner, when the movable nut is screwed, an arc sphere generated by the sealing ring can evenly contact with the inner wall of a pipeline, sufficiently high pressure load is generated to realize effective sealing, the rapid plug is simple, convenient and rapid to operate, and maintenance time and intensity are greatly reduced.
Description
Technical field
The utility model relates to a kind of plug, relates in particular to a kind of fast cap that is suitable for the expansion-pressure type of gas pipeline.
Background technique
Plug is that unwanted mouth in the pipeline is blocked up, and plays sealing process.Existing fast cap is to belong to interior expansion stifled shape outward, and the plug of this structure is easily produced along with the increase of gas pressure, repeats leak-down rate large, has potential safety hazard, is difficult to reach promising result.
The model utility content
The utility model purpose is the fast cap that a kind of efficient, safety and good sealing effect are provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of fast cap, comprise bolt, described bolt comprise hexagon-head and with hexagon-head be holistic screw rod; Described screw tip is fixedly connected with a baffle plate; Described baffle plate is to being provided with successively traveling nut, the first pressing plate, seal ring, the second pressing plate between the hexagon-head; Described seal ring adopts rubber material to make.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of fast cap of the present utility model, the sealing of employing expansion-pressure type, when tightening traveling nut, under the effect of the first pressing plate, the circular arc spherical surface that seal ring produces can evenly contact with inner-walls of duct, produce enough large pressure loading and play effective sealing, easy and simple to handle and quick, greatly reduce repair time and maintenance intensity.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the three-dimensional structure diagram of a kind of fast cap of the present utility model;
Accompanying drawing 2 is the sectional view of a kind of fast cap of the present utility model;
Wherein: 1, hexagon-head; 2, screw rod; 3, baffle plate; 4, traveling nut; 5, the first pressing plate; 6, seal ring; 7, the second pressing plate.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
