Technical field
The utility model relates to a kind of pulsed charger of closed external pressure vessel, belongs to the external pressure test field.
Background technology
The closed external pressure test occupies very consequence in each external pressure test research.
During but compacting was tested outside, prior art can only realize under static state that external pressure is static and be loaded into certain load.
In real daily life, the external pressure that bears not is only static to certain load, but along with the variation of state, bear different load, the external pressure stressing conditions is different constantly, existing external pressure test can only be simulated a fixed load, can't simulate the external pressure situation that external pressure vessel is subjected in the loading process.
Summary of the invention
For fear of the deficiencies in the prior art part, the present invention proposes a kind of pulsed external pressure test charger of closed external pressure vessel, and solution can't be simulated dynamic external pressure problem.
A kind of pulsed charger of closed external pressure vessel is characterized in that comprising O-ring seal 1, set bolt 2, sealing bolt 3, pressurization top cover 4, lighter 5, unloads pressure mouth 7, through hole 10, external pressure vessel 8 and fairlead 9; External pressure vessel 8 has the cavity structure of outer for two ends, and an end is a through hole, and other end center hole is provided with fairlead 9; Through hole is fixedlyed connected by set bolt 2 with pressurization top cover 4, and O-ring seal 1 is positioned in the seal groove of pressurization top cover 4; Lighter 5 is located in the center pit of pressurization top cover 4, adopts sealing bolt 3 fixing; The edge of external pressure vessel 8 is provided with some pressure mouthes 7 that unload, and unloads pressure mouth 7 both sides and is provided with through hole 10; Described fairlead 9 is combined closely with the center hole diameter of the external pressure vessel 8 that passes for the right cylinder of band boss, cylindrical smaller diameter end, and larger diameter end electrically connects with the foil gauge that is attached on the test specimen; Described pressure mouth 7 inside of unloading are through-hole structure, place the top of external pressure vessel 8 fixed bits; Described through hole is provided with movable drain plug.
Described pressure mouth 7 interior bone of unloading are boss structure.
Described through hole 10 is a water inlet.
Described through hole 10 is a pressure tap.
The pulsed charger of the closed external pressure vessel that the present invention proposes uses lighter to load external pressure, can make external pressure reach required value at short notice, opens certain pressure relief vent on frock, and external pressure is unloaded at short notice.Can satisfy the needs of closed external pressure test.

Embodiment
Now in conjunction with the embodiments, accompanying drawing is further described the utility model:
The structure of present embodiment comprises O-ring seal 1, set bolt 2, sealing bolt 3, pressurization top cover 4, lighter 5, unloads pressure mouth 7, through hole 10, external pressure vessel 8 and fairlead 9; External pressure vessel 8 has the cavity structure of outer for two ends, and an end is a through hole, and other end center hole is provided with fairlead 9; Through hole is fixedlyed connected by set bolt 2 with pressurization top cover 4, and O-ring seal 1 is positioned in the seal groove of pressurization top cover 4; Lighter 5 is located in the center pit of pressurization top cover 4, adopts sealing bolt 3 fixing; The top outer rim of external pressure vessel 8 is provided with 3 and unloads pressure mouth 7, unloads pressure mouth 7 inside and is the boss through-hole structure; Unload pressure mouth 7 both sides and respectively be provided with 3 through holes 10, as water inlet or pressure tap, through hole is provided with movable drain plug; Described fairlead 9 is combined closely with the center hole diameter of the external pressure vessel 8 that passes for the right cylinder of band boss, cylindrical smaller diameter end, and larger diameter end electrically connects with the foil gauge that is attached on the test specimen.
Testpieces is installed: at first testpieces 6 is pasted foil gauge, the data line of foil gauge is connected with fairlead 9 bonding wires, then testpieces 6 is fixed in external pressure vessel 8 bottoms, 9 fairleads are drawn from the through hole of external pressure vessel 8 one ends, and seal.O-ring seal 1 is positioned in the seal groove of pressurization top cover 4, uses set bolt 2 that pressurization top cover 4 is installed; By select in the through hole 10 three as water inlet to charging into water in the external pressure vessel 8, with plug water inlet is sealed again after water-filling is finished; Other 3 through hole sensor installations and sealing; The mounting points firearm 5 then, use fixedly dead point firearm of sealing bolt 3 at last, install.
At the trial, the mounting points gunpowder, schematic diagram as shown in Figure 4, this test external pressure is applied by the igniting tablet, during test, the tablet of will lighting a fire is earlier installed and lighter, frocks such as installation test part, light a fire during official test, igniting produces the thrust to external pressure vessel, by WATER AS FLOW MEDIUM external pressure is applied on the testpieces, and testpieces produces instantaneous outer compressive strain, meanwhile, unload pressure mouth and simultaneously the discharge degree that produces is fallen, promptly unload the pressure mouth draining, reached the purpose of release simultaneously, so this device realized external pressure and loaded simultaneously, Xie Zai purpose simultaneously.Simultaneously, with test figure output, the sensor of installing on 3 through holes is with the pressure datas output of test in the external pressure vessel 8 by fairlead 9 for the stress that is attached to the foil gauge induction on the testpieces 6.
