Abstract
The utility model relates to a hydraulic pressure test device, by which hydraulic pressure tests can be safely and reliably conducted. A sealing fixed pressure gauge is arranged at a middle opening of a threeway hand lever, two ends of the threeway hand lever are respectively connected with an adjusting bolt and a connector. In test, clean water is injected into the hand lever, pressure of the water is adjusted by adjusting the adjusting bolt, and then the hydraulic pressure test can be conducted. The test device is simple in structure, safe and reliable.
Description
Design field
The utility model relates to a kind of pressure test device, especially a kind of hydrostatic test device.
Technical background
For the steam turbine pressure part that carries high pressure, adopt the hydraulic testing to verify the reliability and the security of its design, workmanship usually, whether the examination pressure part seepage takes place under test pressure.Whether the general hydraulic testing is connected pump through being with manometric water pipe with pressure part, and above pressure part, a tensimeter is installed in addition, descend through two pressure gauge pressures of visual inspection test, judges whether the steam turbine pressure part is qualified.In this detects operation, at first should before test, check water system, guarantee that water system do not have leakage phenomenon; The water pipe quality is checked; Anti-antipriming pipe is aging, causes explosion phenomenon generation in the pressure testing process, should guarantee that simultaneously pump starts, supplies power when cutting out normal; Avoid electric leakage, electric shock phenomenon to take place, in proof procedure, have many risk hidden danger in a word.
Summary of the invention
The purpose of the utility model is a kind of easy and simple to handle, easy accessibility of design, water test unit simple in structure.The technical scheme of the utility model is so to realize:
A kind of water test unit; Comprise regulate bolt, hand-held pole, tensimeter, jointing; Said is hand-held pole three-port structure, and the tensimeter sealing and fixing is regulated bolt and jointing and is connected on the port of two symmetries in addition of hand-held pole on the port middle hand-held pole.
As preferably, said manometric range is 1.5～3 times of testing pressure.
The water test unit of the utility model design, by regulating bolt, forming hand-held pole, tensimeter, jointing, hydraulic test pressure is 1.5 times of pressure part MWP; Tensimeter adopts the qualified tensimeter of periodic calibration; Range is 1.5～3 times of test pressure, and the tensimeter sealing and fixing that periodic verification is qualified is tightly connected with pressure part with hand-held pole with jointing on hand-held pole; Injecting a certain amount of clean water to the other end of hand-held pole subsequently; It is charged into to the tested position of pressure part, and will regulate bolt with spanner and be screwed into a hand-held pole, observe pressure gauge reading and change.During test, the rising of pressure should slowly be carried out, when pressure rises to working pressure; Time-out boosts, and carries out trial inspection, if ne-leakage or other abnormal occurrencies; Can boost to test pressure again, and under test pressure, keep the designing institute official hour, and carry out scrutiny.During the inspection, pressure should remain unchanged.Subsequently, will regulate bolt and unclamp, water is discharged, whole like this hydraulic testing process is accomplished.The utlity model has easy and simple to handle, easy accessibility, characteristics such as simple in structure.
Description of drawings
Accompanying drawing is a kind of structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing,, do further bright specifically to the technical scheme of the utility model through embodiment.
Embodiment: with reference to accompanying drawing; A kind of water test unit; Comprise regulate bolt 1, hand-held pole 2, tensimeter 3, jointing 4; Is hand-held pole 2 three-port structure, and tensimeter 3 sealing and fixing are regulated bolt 1 and are connected on the port of two symmetries in addition of hand-held pole 2 with jointing 4 the port of the centre of hand-held pole 2.
During actual the use, be 30MPa like the designing requirement hydraulic test pressure, pressurize 15min; According to the designing requirement qualified tensimeter 3 of periodic calibration that to select a range for use be 60MPa.With tensimeter 3 sealing and fixing on hand-held pole 2; Be tightly connected with pressure part 5 with hand-held pole 2 with jointing 4; Injecting a certain amount of clean water to the other end of hand-held pole 2 subsequently; It is charged into to the tested position of pressure part, and will regulate bolt with spanner and be screwed into a hand-held pole 2, observe pressure gauge reading and change.During test, the rising of pressure should slowly be carried out, and when pressure rose to 20MPa, time-out boosted, and carried out trial inspection, if ne-leakage or other abnormal occurrencies boost to test pressure 30MPa again, and keeps 15min, and carries out scrutiny.During the inspection, pressure should remain unchanged.Subsequently, will regulate bolt 1 and unclamp, water is discharged, whole like this hydraulic testing process is accomplished.
Claims (2)
1. water test unit; Comprise regulate bolt (1), hand-held pole (2), tensimeter (3), jointing (4); It is characterized in that said is three-port structure to hand-held pole (2); Tensimeter (3) sealing and fixing is regulated on the port of other two symmetries that bolt (1) and jointing (4) be connected to a hand-held pole (2) on the port in the middle of the hand-held pole (2).
