Abstract
The utility model provides a stifled core is sealed to two withholding, is including stifled core body, the head end of stifled core body is to being provided with a recess along the circumferencial direction that blocks up the core body between the tail end, the recess makes stifled core body forms two convex sealed bases, two along the axial in the both sides of annular groove be equipped with the zigzag recess on the lateral surface of sealed base, stifled core body overcoat is equipped with the PU pipe, PU outside of tubes side links closely on sealed base through the ring of withholding that corresponds with sealed base position for PU pipe with block up core body sealing connection, this device can use in the sea water environment of complicacy, advantages such as good, the resistant hydrostatic pressing of corrosion resistance, longe -lived, high reliability height are fit for improving present stifled core.
Description
Technical field
The utility model relates to a kind of pair and withholds seal plug core, is applied to Fibre Optical Sensor field of engineering technology.
Background technology
Now to listen sensor to block up cored structure reliability in briny environment not high for the main piezoelectric type water used, as the stifled cored structure used in sensory field of optic fibre, need long-term in the briny environment of complexity, the sealing of structure, resistance to pressure and corrosion resistance are very important consideration main points; Stifled core is mainly the stifled core of piezoelectric transducer at present, and its sealing structure is inadequate; Inner without any material water-proof material, water resistance is poor; Outside is subject to marine corrosion, unprotect measure, and reliability is not high; Point glue is inconvenient, and structural strength is inadequate, falls short of serviceable life; And the fibre optic hydrophone of a new generation needs decade-long serviceable life in briny environment, for protecting inner vitals not by marine denudation and destruction, more and more urgent to the hermetically-sealed construction demand of high reliability.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and defect and provides a kind of and can use in the briny environment of complexity, and high two of good corrosion resistance, resistance to hydrostatic pressure, life-span long, high reliability withhold seal plug core.
To achieve these goals, the technical scheme that the utility model adopts is:
Withhold seal plug core for a kind of pair, comprise stifled core body, the head end of described stifled core body is provided with a groove along the circumferencial direction blocking up core body between tail end, described groove makes described stifled core body form two sealing bases protruded vertically in the both sides of annular groove, the lateral surface of two described sealing bases is provided with incised groove, PU pipe is set with outside described stifled core body, be held on sealing base by the ring of withholding corresponding with sealing base position outside described PU pipe, the pressure withholding ring makes PU pipe be pressed in incised groove to realize PU pipe and blocks up being tightly connected of core body.
Described PU pipe is wringing fit with the sealing base blocked up on core body.
Described groove is inherent is arranged with two groups of through holes along stifled core body central line on the sealing base medial surface of tail end, often organize through hole and be provided with laterally zygomorphic two through holes, described sealing base is provided with semicircular set collar between two through holes often organized, described traction rope is arranged on set collar by through hole, and stifled core body is all stretched out at the two ends of traction rope.
Material water-proof material layer is filled with in groove between two described sealing bases.
Be provided with the passage arranging main cable in described stifled core body, the outside of described stifled core body is provided with two some glue holes and channel connection along channel direction.
Owing to adopting such scheme, two fastened structures formation dual seals that this device adopts two to withhold ring and compress, and there is filling material water-proof material in two parts of withholding between ring, water resistance and sealing property better, and fastened structure is simple, reliability is high, arranges semicircular set collar for fixed tractive by the groove that is arranged on stifled core body, fixing reliable, prevent traction rope from deviating from a relaxed state.
In sum, this device overcomes piezoelectric transducer and blocks up the defect that core body cannot use in marine environment, also has the advantage such as reliability of better sealing, longer serviceable life and Geng Gao.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is cut-open view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, further describe the embodiment of this patent.
As shown in Fig. 1 to 2, a kind of two withholds seal plug core, comprise stifled core body 4, semicircular set collar 5, PU pipe 1, the packed layer that blocks water withholding ring 2 and be made up of material water-proof material;
Be provided with the passage arranging main cable in described stifled core body, the outside of described stifled core body is provided with two some glue holes and channel connection along channel direction.Shelled the main cable 10 of exterior cover sheets naked fine 7 pass from described passage, in naked fine 7 and the junction of main cable 10, a little sprue 9 is set, thus are sealed in described passage naked fine 7, in order to ensure that naked fine 7 in passage is not corroded by other objects of outside, ensure the sealing of described channel orifices, glue is put in use in a some glue hole, because channel interior is plugged, now gas and the glue of stifled core inner can be discharged in another glue hole 8, the aperture making stifled core inner place naked fibre is filled full by glue, etc. reaching one after glue curing, naked fibre is well sealed and protective effect.
Stifled core body 4 external diameter is a bit larger tham PU pipe 1 internal diameter, ensure that PU pipe 1 can be held on the outside surface of stifled core body 4, withhold ring 2, by pressing machine, the pressure generation amount of withholding is applied to it, make it to be held on PU pipe 1, stifled core body 4 is provided with incised groove 41 in the position of withholding ring 2.
Withhold the value of the amount of withholding of ring 2 and stifled core body 4 outside surface adopts incised groove 41 size to need analyze as calculated according to the model of stifled core to draw, thus ensure that the anti-pull-out force of the sealing of stifled core body 4 and stifled core body 4 joint is sufficient;
The ring 2 of withholding of this device adopts two two fastened structures withholding ring 2, withhold ring 2 for two PU pipe 1 to be pressed on the incised groove 41 of stifled core body 4, part PU pipe 1 is embedded in incised groove 41 and forms stressed joint, in the groove 3 of stifled core body, adopt material water-proof material layer to fill;
This device is managed as watertight connector and PU and the intermediate connection structure part of traction rope 6, and traction rope 6, through the through hole 42 of stifled core body 4 end face, passes from another through hole 42 after walking around semicircular set collar 5, is formed and connects.For preventing traction rope 6 from jumping out from semicircle set collar inside groove in a relaxed state, increase the external diameter of semicircle set collar 5.
