Description
Technical field
The utility model belongs to petrochemical equipment manufacturing technology field, is specifically related to the single hydraulic testing mold of various cold exchange device heat exchanger tubes for the industries such as petrochemical complex.
Background technology
Various shell-and-tube cold exchange devices are very extensive in petroleum chemical industry application.In actual use, as the core parts of heat interchanger-----heat exchanger tube, its quality is directly connected to the normal operation of equipment and even package unit, affects product quality and even causes security incident.So the single hydraulic testing operation of heat exchanger tube heat exchanger tube before assembling is just particularly important, it is the critical process of check heat exchanger tube quality.In order to guarantee that device security is used and product quality, designing unit is in heat interchanger layout design, often require heat exchanger tube to carry out the single hydraulic testing according to national associated fabrication techniques standard, and the existing pressure testing positioner structure of manufacturing plant is complicated, inefficiency, generally carrying out a heat exchanger tube hydraulic testing needs 40min left and right, for a heat interchanger, heat exchanger tube quantity has tens even several thousand, by this efficiency, cannot meet need of production.
Summary of the invention
In order better to guarantee the workmanship of heat interchanger, avoid the outgoing due to whole equipment of indivedual heat exchanger tube quality problems impact, the utility model provides a kind of cold exchange device heat exchanger tube single hydraulic testing mold.
The single hydraulic testing mold of cold exchange device heat exchanger tube, comprises overcoat, O-ring seal, baffle ring, retaining ring.The utility model solves the technical scheme that its technical matters adopts: O-ring seal, baffle ring are put into overcoat successively, and retaining ring adopted and is threaded with being connected of overcoat; Baffle ring, between two O-ring seals, plays the role of fastening, and during the hydraulic testing, O-ring seal water-swellable, with heat exchanger tube close contact, plays good sealing effectiveness; Overcoat is bowl-type, and retaining ring is welding neck flange shape, O-ring seal, baffle ring, is annular, and its size is determined according to the size of heat exchanger tube.
Single hydraulic testing mold comparison with traditional, the utility model has the advantages that:
1, simple in structure, flexible and convenient to use.
2, cost low, be easy to change.
3, can be once many test in batch.
4, be applicable to the heat exchanger tube of all size, when ensuring the quality of products, can effectively increase work efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
(1) overcoat in figure, (2) O-ring seal, (3) baffle ring, (4) retaining ring, (5) heat exchanger tube.
Embodiment
In figure, O-ring seal (2), baffle ring (3) are put into overcoat (1) successively, retaining ring (4) adopts and is threaded with overcoat (1), press seal cushion rubber (2) and baffle ring (3), during the hydraulic testing, insert heat exchanger tube (5), O-ring seal (2) water-swellable, with heat exchanger tube (5) close contact, play good sealing effectiveness, be convenient to check the quality of heat exchanger tube (5).
This utility model is simple in structure, easy to operate, efficiency is high, is suitable for single or many pipes and checks in batches.
