Abstract
The utility model discloses an air bag type air-sealing plug, which comprises a steel framework and a circular rubber board, wherein an air bag fixing ring and an air bag are arranged on the steel framework which is in a circular disk structure; the radius of either outer edge portion of the steel framework is expanded and protruded so that the outer edge portion is formed into half a wheel rim shape; the center of the bottom of the steel framework is welded to a circular steel tube; a lug is welded onto the top of the circular steel tube; after being arranged on the inner side of the air bag, the air bag fixing ring is integrally wrapped with the air bag through a heat insulation cloth tape; the heat insulation cloth tape is wrapped on the air bag fixing ring and the air bag for at least two layers, and then the air bag fixing ring and the air bag are disposed on the outer ring of the steel framework to be fixed; valve ports are respectively arranged on the steel framework and the air bag fixing ring; and the circular rubber board which is disposed at the bottom of the steel framework is pressed on the steel framework through a pressing ring and then fixed onto the steel framework through bolts. The air bag type air-sealing plug has the advantages of being simple and unique in structure, convenient to maintenance and installation, light in weight and beneficial to actual production and operation. Besides, the air pressure inside the air bag is adjustable, and tight air sealing is obtained.
Description
Affiliated technical field:
The utility model relates to a kind of envelope gas blocking device, a kind of air sac type envelope gas blocking device of saying so more specifically.
Background technique:
Envelope gas blocking device is used to extrude moulds the pipe production industry, current China produces platen press in most employing of the outer pillar of high density polyethylene (HDPE) insulation, seal tube wall with envelope gas blocking device during production, charging into pressurized air then in the tubing of extruding continuously holds round tube wall, until the setting of tubing water-cooled, finish the tubing manufacturing.
To be two a pair of Steel Skeletons of usefulness with the thick foam plate of 30-40mm and the thick rubber plate of 15-20mm be clipped in the middle existing envelope gas blocking device fixedly makes, not only heavy but also installation is very difficult in use.
Summary of the invention:
In order to solve problems of the prior art, the utility model provide a kind of structure uniqueness, in light weight, be convenient to mounted airbag formula envelope gas and stop up.
The technical solution of the utility model is: a kind of air sac type envelope gas blocking device, comprise Steel Skeleton and round rubber plate, and described Steel Skeleton is provided with air bag retainer ring and air bag; Described Steel Skeleton is circular tray type structure, the wheel rim shape is protruded in the outer part radius expansion of Steel Skeleton half, the bottom centre of Steel Skeleton and a round steel pipe welding, the welded top hangers of round steel pipe, the maximum diameter of Steel Skeleton is less than pipe internal diameter 100-140mm; Described air bag retainer ring internal diameter greater than Steel Skeleton at the bottom of the footpath 2-4mm, the air bag retainer ring is placed the interior rear flank of air bag, with heat insulation strap air bag retainer ring and air bag are wound in and are one, twine the outer ring that is placed on Steel Skeleton more than two-layer and fix, be equipped with valve port on described Steel Skeleton and the air bag retainer ring; The bottom of described Steel Skeleton is provided with the round rubber plate, by trim ring the round rubber plate is pressed on the Steel Skeleton and is then fixed with bolt.
According to above technological scheme, described air bag is to form with car inner tube of a tyre bonding.Described heat insulation strap is glass yarn strap or woven belt.
The utility model advantage compared with prior art is: 1, uniqueness simple in structure, and the air bag internal air pressure is adjustable, and envelope gas is tight, easy to maintenance; 2, in light weight, easy for installation, be beneficial to the actual production operation.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation that envelope gas stops up in the prior art.
Among the figure: 1, Steel Skeleton, 2, the air bag retainer ring, 3, heat insulation strap, 4, air bag, 5, rubber plate, 6, trim ring, 7, valve port.
Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Referring to Fig. 1, a kind of air sac type envelope gas blocking device, by Steel Skeleton (1), round rubber plate (5), air bag retainer ring (2) and air bag (4) constitute, described Steel Skeleton (1) is circular tray type structure, the outer part radius expansion of Steel Skeleton (1) is protruded into half wheel rim form in order to fixation balloon (4), the bottom centre of Steel Skeleton (1) and a round steel pipe welding, the welded top hangers of round steel pipe, Steel Skeleton (1) can be according to the pipe internal diameter of producing, make with the 6-10mm Plate Steel, its maximum diameter is less than pipe internal diameter 100-140mm, and valve port (7) is arranged at Steel Skeleton (1) bottom.Bonding the forming of the available motorcycle tyre tube of described air bag (4), described air bag retainer ring (2) is made with 30 * 4 band steels, and internal diameter has valve port (7) greater than footpath, Steel Skeleton (1) end 2-4mm.Will air bag (4) suitably again air bag retainer ring (2) be placed the inboard of air bag (4) after the inflation, air bag retainer ring (2) and air bag (4) winding are become one, twine the outer ring that is placed on Steel Skeleton (1) more than two-layer and fix with heat insulation strap (3).The bottom of described Steel Skeleton (1) is provided with round rubber plate (5), and rubber plate (5) is that 10-20mm is thick, and its diameter is pressed on Steel Skeleton (1) by trim ring (6) with round rubber plate (5) and is upward fixed with bolt the back greater than pipe internal diameter 100-140mm.
The actual use when installing tangles the hangers and the mould at round steel pipe top with stay cord or pull bar, bleed off the gas of air bag, charges into an amount of gas behind the installation in position and gets final product.There is the deflation phenomenon to inflate at any time as finding in the production.
The above only is the utility model preferred embodiment, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model is to any simple modification that above embodiment did, and equivalent variations and modification all still belong in the scope of the technical solution of the utility model.
