Model utility content
The purpose of this utility model is to provide a kind of pipe used in mine current-limiting apparatus, and this current-limiting apparatus is connected with tube fit and uses, and structure is simpler, fast, conveniently can realize pipeline current limliting.
To achieve these goals, the technical solution of employing is the utility model:
A kind of pipe used in mine current-limiting apparatus, comprise fuel tank, oil inlet pipe, oil outlet tube and current limiting tube, described fuel tank is connected by the filler opening of oil inlet pipe with current limiting tube upper end, fuel tank is connected by the oil outlet of oil outlet tube with current limiting tube lower end, described oil outlet tube upper end has oil pipe hole, on oil pipe hole, connected pipes hole switch, is provided with hydrovalve switch and one-way valve in oil outlet tube; Described current limiting tube comprises outer tube, interior pipe and contiguous block, and described outer tube is inner connects interior pipe by contiguous block, forms the oil storage tank between outer tube wall and outer wall of inner tube; Described fuel tank is connected with compression pump.
Preferably, described one-way valve is positioned at hydrovalve switch right, and described oil pipe hole is positioned at one-way valve right.
Preferably, described fuel tank upper end has fuel tank hole, fuel tank hole is connected with fuel tank hole switch.
Preferably, described contiguous block is set to four, and four contiguous blocks are divided into the interior edge face being connected to outer tube, and the side end face of described contiguous block has intercommunicating pore, and intercommunicating pore runs through contiguous block.
Preferably, described outer tube and interior pipe all adopt metallic material to make, and the hardness of interior pipe metallic material is lower than the hardness of outer tube metallic material.
The beneficial effects of the utility model are:
The utility model pipe used in mine current-limiting apparatus, the two ends of current limiting tube are connected with needing the pipeline of slip casting respectively, current limiting tube is made up of outer tube and interior pipe, in outer tube is connected by contiguous block, pipe forms the oil storage tank be positioned between inner and outer pipes, current limiting tube is connected with oil pipe device, oil pipe device is connected with fuel tank, when needing to change the aperture in current limiting tube, hydraulic oil in fuel tank enters into oil storage tank by oil pipe device, because interior pipe is made up of the metallic material that hardness is lower, along with increasing of hydraulic oil in oil storage tank, the internal pipe of hydraulic oil applies pressure, interior pipe generation deformation, the internal diameter of interior pipe is changed, realize the current limliting to fluids within pipes.This device being controlled the inner pore size of current limiting tube by hydraulic transmission system, structure is simpler, fabricating cost is lower, removable parts part is only needed when pipe used in mine current-limiting apparatus goes wrong, the maintenance cost in later stage is lower, and the inner pore size of current limiting tube can be controlled by the switch of regulating oil tank and oil pipe device, operate more simple and practical.
Accompanying drawing explanation
Fig. 1 is the overall sectional structure schematic diagram of pipe used in mine current-limiting apparatus.
Embodiment.
Below in conjunction with accompanying drawing, the utility model is described in detail:
Composition graphs 1, a kind of pipe used in mine current-limiting apparatus, comprises fuel tank 1, current limiting tube 2, oil inlet pipe 3 and oil outlet tube 4, described fuel tank 1 is connected with compression pump 11, oil pressure size in the controlled liquefaction case 1 of compression pump 11, one end of fuel tank 1 has fuel tank hole 12, fuel tank hole 12 is connected with fuel tank hole switch 13.Described current limiting tube 2 comprises outer tube 21, interior pipe 22 and contiguous block 23, outer tube 21 connects interior pipe 22 by contiguous block 23, form the oil storage tank 24 between outer tube 21 inwall and interior pipe 22 outer wall, outer tube 21 upper end has filler opening 211, and outer tube 21 lower end has oil outlet 212.Fuel tank 1 is connected with the filler opening 211 of current limiting tube 2 upper end by oil inlet pipe 3, and fuel tank is connected with the oil outlet 212 of current limiting tube lower end by oil outlet tube.Described contiguous block 23 is set to four, four contiguous blocks 23 are connected to upper and lower, left and right four end of outer tube 21 interior edge face, the side end face of described contiguous block 23 has intercommunicating pore 231, intercommunicating pore 231 runs through contiguous block 23, under the effect of contiguous block 23, oil storage tank 24 is divided into four parts, by intercommunicating pore 231, tetrameric oil storage tank 24 is connected together, described outer tube 21 and interior pipe 22 all adopt metallic material to make, and the hardness of interior pipe 22 metallic material is lower than the hardness of outer tube 21 metallic material.
Described oil outlet tube 4 has oil pipe hole 41, oil pipe hole 41 is provided with oil pipe hole switch 42, one-way valve 43 is provided with in the oil outlet tube 4 of oil pipe hole 41 left end, hydrovalve switch 44 is provided with in the oil outlet tube 4 of one-way valve 43 left end, when one-way valve 43 has hydraulic oil through out-of-date, oil can only flow to left from the right of one-way valve 43.
The working principle of the utility model pipe used in mine current-limiting apparatus is: be connected to by current limiting tube 2 between two pipelines, during normal work, first fuel tank hole switch 13, hydrovalve switch 44 are closed, oil pipe hole switch 42 is opened, then compression pump 11 pressurizes, and hydraulic oil enters in oil storage tank 24 along oil inlet pipe 3; Meanwhile, the air in oil storage tank 24 is got rid of through oil pipe hole switch 412, closes oil pipe hole switch 42; After oil is full of whole oil storage tank 24, the metallic material adopting hardness higher due to outer tube 21 is made, and the metallic material that interior pipe 22 adopts hardness lower is made, and interior pipe 22 shrinks under the effect of oil pressure, the internal diameter size of whole interior pipe 22 reduces, thus can play the effect of current limliting; After hours, close compression pump 11, open fuel tank hole switch 13, hydrovalve switch 44, oil is got back in fuel tank 1 by oil outlet tube 4 under gravity, now oil storage tank 24 is vacuum state, under the fluid pressure action such as the mud in pipeline, interior pipe 22 is set back.
