Description
Technical field
The utility model relates to technical field of electric wires and cables, particularly relates to a kind of deep-sea cable radial direction and longitudinal water-blocking pressure test device.
Background technology
At present, cable is tested without special test equipment at the block-water performance of the radial direction had under hydraulic pressure and longitudinal direction, along with cable is more and more applied in deep water, the test of the watertightness performance of cable under hydraulic pressure, block-water performance just seems particularly important, the utility model aims to provide the inspection machine of a kind of longitudinal water-blocking of cable easily, radial water-resisting performance, wherein by converting simply, longitudinal water-blocking can the overall longitudinal water-blocking performance of detection streamer and the cable longitudinal water-blocking performance except insulation.
Summary of the invention
The purpose of this utility model is the deficiency overcoming above-mentioned technology, and provides a kind of deep-sea cable radial direction and longitudinal water-blocking pressure test device, meets cable radial direction and the testing requirements of longitudinal water-blocking pressure.
The utility model for achieving the above object, by the following technical solutions: a kind of deep-sea cable radial direction and longitudinal water-blocking pressure test device, it is characterized in that: comprise steel pipe, the two ends of described steel pipe are respectively equipped with screwed union, described screwed union coordinates with gland bonnet or cecum gland bonnet, is provided with packing ring and U-shaped rubber blanket between described screwed union and gland bonnet, and described steel pipe top is provided with tensimeter and pressure relief opening, steel pipe bottom is provided with water inlet, and described water inlet is connected with forcing pump by water inlet pipe.
The bottom of described steel pipe is provided with bracket.
Described steel pipe is placed on described bracket horizontal by 5 degree of angles.So that the air in emptying equipment.
The internal orifice dimension of described gland bonnet is greater than outside diameter of cable 0.5-1.0mm to be tested.
The beneficial effects of the utility model are: the utility model structure is simple, and a) adopt screwed union, U-shaped O-ring seal, packing ring, gland bonnet to combine, hydraulic pressure is larger, seals tighter, solves the difficult problem sealed between cable and equipment.B) structure is simple, and easy to manufacture, convenient experimental operation, cost is lower, is convenient to penetration and promotion.C) by simple transformation, be applicable to the radial direction of cable water pressure and the use of direction waterproof performance test simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, a kind of deep-sea cable radial direction and longitudinal water-blocking pressure test device, be made up of gland bonnet 1, packing ring 2, U-shaped rubber blanket 3, screwed union 4, pressure relief opening 5, tensimeter 6, the steel pipe 7 with spiral interface, bracket 8, water inlet 9, cecum gland bonnet 10, forcing pump 11.
During radial watertight performance test, cable from gland bonnet 1, packing ring 2, U-shaped rubber blanket 3, screwed union 4, with spiral interface steel pipe 7 in the middle of pass, both sides are by installing in U-shaped O-ring seal 3 to screwed union 4, metal washer 2 is compressed U-shaped O-ring seal 3, screwing hermetic lid 1, by gap seals between cable cover(ing) and steel pipe 3; By water inlet 9 water-filling in steel pipe 7, observe water in steel pipe by pressure relief opening 5 and whether be full of completely, be full of rear closedown pressure relief opening 5; Forcing pump 11 is connected with the water inlet 9 on steel pipe by flexible pipe, starts forcing pump 11, for providing hydraulic pressure in steel pipe 7; According to testing requirements, when hydraulic pressure reaches trial value, turn off forcing pump, pressurize is to test required time, and period slightly falls situation if any pressure, can start forcing pump 11 ftercompction at any time; After reaching the test duration, open water inlet 9 pressure release, bleed off the water in steel pipe 7, cable is extracted out from steel pipe 7, dissect cable and observe flooded condition.
Except insulation except direction waterproof performance test time, dismiss 10cm sheath in the centre position of cable sample, repeat above-mentioned action.
During the performance test of whole cable direction waterproof, cable is from the gland bonnet 1 of side, packing ring 2, U-shaped rubber blanket 3, screwed union 4, pass with in the middle of the steel pipe 7 of spiral interface, opposite side changes gland bonnet 1, packing ring 2, U-shaped rubber blanket 3 into cecum gland bonnet 10, and the test action of repeat radial watertightness performance can complete direction waterproof performance test.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from 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.
