The pipe cap is the cup body that outer surface has ring-shaped groove;
The clip includes that two cross sections are U-shaped semicircle steel loop, and two ends of the semicircle steel loop are equipped with bending edges,
The bending edges are equipped with through-hole, and the fastener, which is worn, is fixedly connected to form circular steel for two semicircle steel loops in through-holes
Ring;
The circle steel ring cap is set to the ring-shaped groove of the pipe cap;
The sealing ring is set to the inside of the round steel loop.
Wherein, the sealing ring is self-locking seal circle.
Wherein, the fastener is hex bolts and nut.
Wherein, the inner and outer diameter of the pipe cap and the inner and outer diameter of tested pipeline are equal.
Wherein, the material of the clip is hardened steel.
It has been connect the utility model has the beneficial effects that: equipment is taken over by clip and sealing ring with test pipe cap
Come, forms a reliable sealing flange structure.To the end of pressure testing, by equipment conveying to erecting bed, directly unscrewing is tight
Firmware unlocks clip, can be with the Pipe installing of outside.In-site installation difficulty is enormously simplified, while avoiding gas cutting generation
Welding slag fall into inside pipeline, ensure that system clean degree.
Detailed description of the invention
Fig. 1 show the knot of the sealing device for pipeline mesolow pressure testing of specific embodiment of the present invention
Structure schematic diagram;
Fig. 2 show the tight of the sealing device for pipeline mesolow pressure testing of specific embodiment of the present invention
The structural schematic diagram of firmware;
Label declaration:
1, pipe cap;2, clip;3, sealing ring;4, fastener.
Specific embodiment
For technology contents, the objects and the effects that the utility model is described in detail, below in conjunction with embodiment and match
Attached drawing is closed to be explained.
The design of the utility model most critical is: joined the design of pipe cap and clip, after the completion of pressure testing, conveniently tears open
It unloads, and can reuse.
It please refers to shown in Fig. 1 and Fig. 2, a kind of sealing device for pipeline mesolow pressure testing of the utility model,
Including pipe cap 1, clip 2, sealing ring 3 and fastener 4;
The pipe cap 1 is the cup body that outer surface has ring-shaped groove;
The clip 2 includes that two cross sections are U-shaped semicircle steel loop, and two ends of the semicircle steel loop are equipped with bending
Side, the bending edges are equipped with through-hole, and the fastener, which is worn, is fixedly connected to form circle for two semicircle steel loops in through-holes
Steel loop;
The circle steel ring cap is set to the ring-shaped groove of the pipe cap 1;
The sealing ring 3 is set to the inside of the round steel loop.
The course of work of above-mentioned sealing device: when pipeline needs to carry out pressure testing, tested pipeline one end compacting with
The groove that clip 2 matches docks pipe cap 1 with tested pipeline, upper seal 3 is covered, then by clip 2 and tested pipeline and pipe
Two grooves on cap 1 are cooperated, and are fixed with fastener 4;At the end of pressure testing, clip 2 is dismantled, pipe can be carried out
Road connection.
Seen from the above description, the utility model has the beneficial effects that: equipment is taken over by clip 2 and sealing ring 3
It is connected with test pipe cap 1, forms a reliable sealing flange structure.To the end of pressure testing, by equipment conveying to peace
Dress scene, directly unscrewing fastener, unlock clip 2, can be with the Pipe installing of outside.In-site installation difficulty is enormously simplified,
The welding slag for avoiding gas cutting generation simultaneously is fallen into inside pipeline, ensure that system clean degree.
Further, the sealing ring 3 is self-locking seal circle.
Seen from the above description, it when medium enters adapter tube gap, reacts on self-locking seal circle, by self-locking seal circle
The top in groove, forms self-sealing.
