Abstract
A kind of seal for pipe joints linkage structure, comprise the body (1) connected by flange plate, described flange plate comprises the first flange plate (2) and the second flange plate (3), each flange plate is arranged with pair of bolts hole (4), the center hole wall of the first flange plate (2) is provided with ladder annular groove (5), second flange plate (3) inner side is provided with the annular tongue and groove platform (6) of a protrusion in the peritreme place of its center hole, on the outer wall of this annular tongue and groove platform (6), cover has the hot melt block (7) of annular, be connected with its formation tongue and groove in the center hole that the annular tongue and groove platform (6) of the second flange plate (3) can be inserted into the first flange plate (2), the space formed by ladder annular groove (5) between two-phase flange plate can be filled up by extruding after hot melt block (7) heating.It is simple, easy to use and seal reliable advantage that it has structure, is namely applicable to permanent works, is also convenient to dismounting and again utilizes.
Description
Technical field
The utility model relates to a kind of improvement of seal for pipe joints linkage structure.
Background technique
The use of metal (iron) pipeline has the irreplaceable effect of other tubing in a lot of work items.At present, the connection of metallic conduit generally adopts the mode of welding or flange plate to connect.Welding is usually used in large-scale pipeline and connects, and the construction period is longer, and cost is relatively very high, removes difficulty, is applicable to permanent works, and should not be adopted by short-term construction.Flange plate connects to be suitable for be removed and again utilizes, but in its work progress, require will evenly exert a force to each connecting bolt, bolt quantity is numerous, and speed of application is comparatively slow, and easily there is the insecure shortcoming of sealing, once there is seepage in sealing gasket, and will dismounting again.
Summary of the invention
Technical problem to be solved in the utility model is: for the problems referred to above, provides a kind of sealing reliable seal for pipe joints linkage structure.
Technical solution of the present utility model is: it comprises the body connected by flange plate, described flange plate comprises the first flange plate and the second flange plate, each flange plate is arranged with pair of bolts hole, the center hole wall of the first flange plate is provided with ladder annular groove, be provided with the annular tongue and groove platform of a protrusion in the peritreme place of its center hole inside second flange plate, on the outer wall of this annular tongue and groove platform, cover has the hot melt block of annular, be connected with its formation tongue and groove in the center hole that the annular tongue and groove platform of the second flange plate can be inserted into the first flange plate, the space formed by cascade ring groove between two-phase flange plate can be filled up by extruding after the heating of hot melt block.
Technique effect of the present utility model is: it is simple, easy to use and seal reliable advantage that it has structure, is namely applicable to permanent works, is also convenient to dismounting and again utilizes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model first flange plate.
Embodiment
As illustrated in fig. 1 and 2, it comprises the body 1 connected by flange plate, described flange plate comprises the first flange plate 2 and the second flange plate 3, each flange plate is arranged with pair of bolts hole 4, the center hole wall of the first flange plate 2 is provided with ladder annular groove 5, be provided with the annular tongue and groove platform 6 of a protrusion in the peritreme place of its center hole inside second flange plate 3, on the outer wall of this annular tongue and groove platform 6, cover has the hot melt block 7 of annular, be connected with its formation tongue and groove in the center hole that the annular tongue and groove platform 6 of the second flange plate 3 can be inserted into the first flange plate 2, the space formed by ladder annular groove 5 between two-phase flange plate can be filled up by extruding after hot melt block 7 heats.
The madial wall of described first flange plate 2 is provided with the spilling duct 8 of at least one and ft connection.
Hot melt block 7 cross section can adopt rectangle, and volume can be a bit larger tham the volume that ladder annular groove 5 is formed.Hot melt block 7 heat fused, to after to a certain degree, by two flange plate docking, just can complete connection by two bolts, formation reliable sealing fast.Overflow duct 8 to can be used to observe filling effect and discharge air.First unclamp the bolt of connection during dismounting, then with blowtorch by hot melt block roastingization, because metal heat-conducting is very fast, unloading process is also very quick.
Claims (2)
1. a seal for pipe joints linkage structure, comprise the body (1) connected by flange plate, it is characterized in that, described flange plate comprises the first flange plate (2) and the second flange plate (3), each flange plate is arranged with pair of bolts hole (4), the center hole wall of the first flange plate (2) is provided with ladder annular groove (5), second flange plate (3) inner side is provided with the annular tongue and groove platform (6) of a protrusion in the peritreme place of its center hole, on the outer wall of this annular tongue and groove platform (6), cover has the hot melt block (7) of annular, be connected with its formation tongue and groove in the center hole that the annular tongue and groove platform (6) of the second flange plate (3) can be inserted into the first flange plate (2), the space formed by ladder annular groove (5) between two-phase flange plate can be filled up by extruding after hot melt block (7) heating.
2. seal for pipe joints linkage structure as claimed in claim 1, is characterized in that, the madial wall of described first flange plate (2) is provided with the spilling duct (8) of at least one and ft connection.
