Centre has a water injection hole, and this water injection hole is connected with water inlet pipe 7, water inlet pipe 7 other end with add
Water pump 8 connects, and has a water tank 9 to pass through outlet pipe 10 and add immediately below test bed framework 4
Water pump 8 connects, and pressure pump 8 upper end connects a water pressure gauge 11, starts pressure pump
8, make, by measuring tank cover 1 internal water flooding, to treat that water pressure gauge 11 reaches the force value of regulation, pressure (hydraulic) water
Pump 8 quits work, and observes by the state of measuring tank cover 1.After test, control hydraulic jack
5 promote push rod 6, make tested case cover 1 internal pressure relief, and water is back to water through rubber slab 3
In case.The shortcoming of this test method is: (1) push rod is to the thin case cover of cast aluminium material wall or casing
Class part applies pressure, causes rupturing.(2) part is thin due to wall, is applying certain pressure
Time make rubber slab be easy for being cut bad.
(3) utility model content:
The purpose of this utility model is to provide a kind of flameproof enclosure water test unit, and it is one
Kind of simple in construction, easy to install, do not damage by measuring tank cover and test equipment to flame-proof type
The flameproof enclosure of electric device for valve carries out the device of the water pressure test.
The technical solution of the utility model: a kind of flameproof enclosure water test unit, it includes close

Water pressure gauge, described water tank is positioned at the underface of test bed framework；It is characterized in that it also includes solid
Fixed rack and O RunddichtringO, described fixed support be fixed in test bed framework and with by measuring tank
Cover is fixing to be connected, and described O RunddichtringO seals fixed support and by the junction of measuring tank cover, institute
Stating fixed support and have a water injection hole, the described water inlet pipe other end is with the water injection hole on fixed support even
Connect.
Support bracket fastened underrun screw described above is fixed on the base plate of test bed framework.
Support bracket fastened endoporus described above with carried out the face of cylinder by the cylindrical fit face of measuring tank cover
And end face join merga pass screw fastening.
O RunddichtringO described above is arranged in support bracket fastened cylinder deep gouge, and with by measuring tank
The face of cylinder and the end face binding site of cover match.
Work process of the present utility model: start pressure pump, make by measuring tank cover internal water flooding,
Treating that water pressure gauge reaches the force value of regulation, pressure pump quits work, and observes by the shape of measuring tank cover
State.After test, unclamp by the trip bolt between measuring tank cover and fixed support, make tested
Examination case cover internal pressure relief, water is back in water tank.
Advantage of the present utility model and good effect be: 1, removes the portion such as hydraulic jack and push rod
Part, has saved the cost of testing stand, eliminates the hidden danger that hydraulic jack damages；2, removal pushes away
The pressure that pole pair is applied by measuring tank cover, eliminate that the case cover caused because of external pressure destroys because of
Element, the percent defective making external factor cause reduces to zero；3, reduce hydraulic jack and push rod side
The control in face, makes more convenient operation.
