Press pump connecting tube and pressure gauge, the other end add adjutage, blast pipe and pressure gauge, and its water quality of hydraulic test of pipeline should be clean,
Water-filling, which should ensure that, to drain air in system.Pipeline work pressure is 0.3MPa, test pressure 0.45MPa.Pipeline should divide
Level boosting, every liter of one-level should check pipe shaft and interface, when phenomenon without exception, be further continued for boosting.During the water pressure test, pipe
The pressure that road port closure plate section is born is big, and by taking million units as an example, it is 3840 × 20mm of φ to be typically designed specification.Power plant cycle
Waterpipe operating pressure is 0.3MPa, test pressure 0.45MPa.Using conventional closure plate, during the water pressure test, reach examination
After pressure pressure (0.45MPa), conduit section bears pressure and is up to 520888Kg, causes larger peace be present during the water pressure test
Full blast danger.Therefore, design it is a can effectively reduce conduit section and bear pressure, effectively improve the safety during the water pressure test
Power plant's special end socket of the heavy caliber circulating water pipeline water pressure test of property is research purpose of the present utility model.
Utility model content
For in place of above-mentioned the shortcomings of the prior art, the utility model is to provide a kind of power plant's heavy caliber recirculated water
The special end socket of hydraulic test of pipeline, the special end socket of the water pressure test can effectively reduce conduit section and bear pressure, effectively improve
Security during the water pressure test.
The technical solution of the utility model is:A kind of special end socket of power plant's heavy caliber circulating water pipeline water pressure test, comprising
Bottom plate, cone and steel pipe, it is attached between the bottom plate and the steel pipe by the cone, the outside of the steel pipe
It is provided with one layer of corresponding strengthening groove stirrup;Cross reinforcement, institute are fixedly installed between the bottom plate and the cone
State and be fixedly installed multiple stiffening angles by angularly distribution between cone and the steel pipe;The side of the strengthening groove stirrup
One group of corresponding reinforcing mechanisms is symmetrically arranged with, the reinforcing mechanisms include the reinforcement for being arranged at the strengthening groove stirrup lateral surface
Cover plate, described to strengthen being provided with reinforcement side plate above cover plate, the upper end strengthened side plate and be arranged at the strengthening groove stirrup
Face.
The cross reinforcement is made by the steel plate that thickness is 10-12mm, and the stiffening angle is by thickness
It is made for 8-10mm steel plate.
The reinforcement cover plate is prepared with the reinforcement side plate by thickness 8-10mm steel plate.
The advantages of the utility model:The utility model can effectively reduce conduit section and bear pressure, effectively improve hydraulic pressure
Security during experiment.By taking million units as an example, it is 3840 × 20mm of φ to be typically designed specification.Electric power plant circulating water pipeliner
It is 0.3MPa, test pressure 0.45MPa to make pressure.Using the utility model as special end socket, during the water pressure test,
After reaching pressure test pressure (0.45MPa), conduit section bears pressure and is:3.14×(100cm/2)×(100cm/2)×4.5Kg/
Cm2=35325Kg, small more of pressure 520888Kg are born more than the conduit section using conventional closure plate.Comparing more than can
Done with finding out using special end socket during closure can substantially reduce the water pressure test, the pressure that pipe end closure plate section is born,
Security risk during the water pressure test can so be greatly lowered.And after making, this end socket can be used as fixed assets to repeat to make
With multiple, in the long term, not only ensure that the safe and reliable of water pressure test work, also reduce engineering cost, be worthy to be popularized and
Using.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side view of the present utility model.
Embodiment
To improve those skilled in the art to understanding of the present utility model, now by embodiment combination accompanying drawing further to this reality
Illustrated with new.
With reference to figure 1-2, a kind of special end socket of power plant's heavy caliber circulating water pipeline water pressure test, bottom plate 1, cone 2 are included
With steel pipe 3, it is attached between the bottom plate 1 and the steel pipe 3 by the cone 2, the outside of the steel pipe 3 is provided with
One layer of corresponding strengthening groove stirrup 4;Cross reinforcement 5 is fixedly installed between the bottom plate 1 and the cone 2, it is described
Between cone 2 and the steel pipe 3 12 stiffening angles 6 are fixedly installed by angularly distribution;The side of the strengthening groove stirrup 4
