Description
Technical field
The utility model relates to a kind of foreign trade tank car pressure testing device, and the hydraulic testing work for the foreign trade tank body of tank car, belong to the pressure test device field.
Background technology
For the field that fully opens up a market, improve the international popularity of industry.Recent year railway freight-car dominant Design producer has all strengthened the development dynamics of foreign trade railway freight-car.
The Special Railway Tank Vehicle of Central Asia state is different from China Special Railway Tank Vehicle structure, and former structure is more complicated.Especially at the tank body material and aspect requiring, different from state iron car, the environment temperature-60 that this car requires ~+50 ℃, hydraulic test pressure is 0.9MPa, and the upper plane of this car manhole collar is welded with a circle round steel, and sealing is poor, and the environment temperature-40 that state's iron car requires ~+50 ℃, hydraulic test pressure is 0.4MPa, above the manhole collar, is plane.So, in order to guarantee the quality of foreign trade tank car, must carry out pressure test to the tank car of producing.
Summary of the invention
The purpose of this utility model is for the quality that guarantees the foreign trade tank car, completes tank hydraulic pressure test, and a kind of foreign trade tank car pressure testing device is provided.
The purpose of this utility model realizes with the following methods:
The utility model comprises platen, it is characterized in that: on platen, be connected with water inlet pipe, rising pipe, gas outlet, pressure test pipe, water inlet pipe connects water supply connector by a water intake ball valve, rising pipe connects water out adapter by a water outlet ball valve, the gas outlet end connects a venting ball valve, and the pressure test tube end is connected with tensimeter by pressure test ball valve, connecting tube, pressure tapping.
Bottom at described platen has annular seal groove, in seal groove, is provided with sealing gasket.
At the edge of described platen by being evenly distributed in bolt slot.
The utility model has the advantages that: simple in structure, accurate positioning, parts interchangeability is good, and convenient operation can high-quality, the high efficiency tank hydraulic pressure test that completes the foreign trade tank car.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the upward view of platen.
Embodiment
With reference to accompanying drawing, the utility model comprises platen 19, on platen, be connected with water inlet pipe 1, rising pipe 12, gas outlet 14, pressure test pipe 3, the water inlet pipe pipe end connects water intake ball valve 2 by elbow 15, nipple 16, water intake ball valve connects water supply connector 17, rising pipe is connected with water outlet ball valve 10 by elbow 8, connecting pipe 9, the water outlet ball valve connects water out adapter 11, the gas outlet end connects venting ball valve 18, and the pressure test tube end is by internal thread pressure test ball valve 4, bend pipe 7, pressure tapping 6 Bonding pressure tables 5.Bottom at platen has annular seal groove, in seal groove, is provided with sealing gasket 13; At the edge of platen by being evenly distributed in eight bolt slots 20.During use, open manhole cover, the utility model is placed on to the manhole collar upper, with platen 19, utilize the bolt on the manhole collar to be connected the manhole collar, sealing gasket 13 can guarantee that both are closely connected.Respectively water supply connector 17, water out adapter 11 are connected with water pipe, can carry out hydraulic testing work.
