Abstract
The utility model discloses a mine flameproof transformer static pressure test device. The device comprises a water inlet pipe valve (1) and is characterized in that the water inlet pipe valve (1) is directly connected with a tested flameproof transformer box body (8); the bottom end of an upward elbow (5) is connected with the tested flameproof transformer box body (8) through a standard connection square flange (6); an exhaust pipe valve (2) and a pressure gauge (3) are arranged on the top end of the upward elbow (5); one end of a hose (4) is connected with the exhaust pipe valve (2); and the other end is connected with a float ball with holes and comes into the tested flameproof transformer box body (8). The mine flameproof transformer static pressure test device provided by the utility model reasonably uses a communicating principle to carry out exhaust to avoid damage caused by lifting the flameproof transformer box body, and has the advantages of safe and convenient operation, no air dead angle and accurate pressure test value.
Description
Technical field
The utility model relates to a kind of mining explosion-proof transformer static pressure test apparatus, is specially adapted to the static pressure test of the explosion-resistant enclosure of relatively large ripple drum type brake FLP drill transformer, belongs to hydraulic technique field.
Background technology
Traditional mining explosion-proof transformer, in case top, have hand hole cover plate, can use for the exhaust of intaking in case, and ripple cylinder type flameproof cabinet adopts the ripple struction of a hydroforming, and perforate cannot be set at top, therefore when casing water inlet plane surpasses terminal box position, two ends, headroom and surface level form enclosure space, gas in enclosure space cannot be discharged, and can not meet the requirement to static pressure test in standard.
Common more small-sized ripple drum type brake explosion-proof casing, can utilize the row of higher tonnage to hang with station frame holds up whole casing so that air is discharged from top, the shortcomings such as quantities is large, processing safety is poor, the omnidistance row that needs hangs cooperation and this way exists, and exhaust is incomplete.
Utility model content
Technical problem to be solved in the utility model is that the mining explosion-proof transformer static pressure test apparatus of the tested Flameproof transformer casing inner sealing of a kind of effective discharge region gas is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of mining explosion-proof transformer static pressure test apparatus, comprise: water inlet pipe valve, it is characterized in that: described water inlet pipe valve is directly connected with tested Flameproof transformer casing, upwards bend pipe bottom connects tested Flameproof transformer casing by standard connection side flange, described upwards bend pipe top is provided with blow off valve and tensimeter, flexible pipe one end is connected with described blow off valve, and the other end is connected with ball float with holes and passes in tested Flameproof transformer casing.
The overall height of described upwards bend pipe surpasses the height of tested Flameproof transformer casing.
The specification of described standard connection side's flange is 490 * 490mm square flange.
The mining explosion-proof transformer static pressure test apparatus that the utility model provides, rationally utilizes law of connected vessels to carry out exhaust, and avoid slinging Flameproof transformer casing and cause damage, handling safety, easy, without air dead angle, pressure testing value is more accurate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is enforcement schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1-2, a kind of mining explosion-proof transformer static pressure test apparatus, comprise: water inlet pipe valve 1, it is characterized in that: described water inlet pipe valve 1 is directly connected with tested Flameproof transformer casing 8, upwards bend pipe 5 bottoms connect tested Flameproof transformer casing 8 by standard connection side flange 6, described upwards bend pipe 5 tops are provided with blow off valve 2 and tensimeter 3, and flexible pipe 4 one end are connected with described blow off valve 2, and the other end is connected with ball float 7 with holes and passes in tested Flameproof transformer casing 8.
The overall height of described upwards bend pipe 5 surpasses the height of tested Flameproof transformer casing 8.
The specification of described standard connection side's flange 6 is 490 * 490mm square flange.
Principle of work of the present utility model: when Flameproof transformer casing 8 is carried out to the hydraulic testing, standard connection side flange 6 and the square flange of Flameproof transformer casing 8 are connected and sealed, the ball float with holes 7 simultaneously flexible pipe 4 being connected is placed in tested Flameproof transformer casing 8, first from bend pipe 5 tops that make progress, carry out fast water injection to filling with, now ball float 7 with holes is on the water surface, now open after blow off valve 2, open into water pipe valve 1, by forcing pump to charged pressure water in tested Flameproof transformer casing 8, the gas in tested Flameproof transformer casing 8 top seal spaces can be discharged from blow off valve 2 from duct and the flexible pipe 4 of ball float 7 with holes, until all without gas, while being all water discharge, illustrate that the air in tested Flameproof transformer casing 8 drains, close blow off valve 2, entering along with press water in tested Flameproof transformer casing 8 now, observe tensimeter 3, monitor pressure in tested Flameproof transformer casing 8 while increasing to 1MPa, close into water pipe valve 1, maintain pressure and continue 10+2S, casing is answered ne-leakage, without distortion, for qualified.After pressure testing finishes, open blow off valve 2, carry out pressure release to normal pressure, complete pressure testing process.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
