Description
Technical field
The present invention relates to a kind of sealing device, especially relate to a kind of rubber covered wire vulcanization sealing device that is exclusively used in cable conductor.
Background technology
As everyone knows, the rubber continuous vulcanization equipment that present domestic cable machinery manufacturing firm produces mostly is simple production line, gone out end seal in the cable production process after, use the cooling water sealed steam, keep certain pressure.Multiple functional fewer in the present of home make rubber continuous vulcanization production line, majority is the most basic form.Multiple functional production line all has the moisture balance device, and the cooling section of certain-length is arranged in pipeline, and product is cooled off under pressure, avoids cooling off under the normal pressure situations such as issuable bubble.An important foundation of moisture balance device is exactly will guarantee end seal reliable, and the bore size of end seal circle is quite important with cooperating of product external diameter, when producing cable, one section lead-in wire must be arranged, for fitted seal circle bore size, just require the diameter that goes between and the identical Zhao of product diameter like this, in order to produce the cable of all size, just require to prepare abundant lead-in wire, cause a large amount of occupied funds.
The way that addresses this problem at present is to increase sealing together (lead-in wire sealing) endways after the sealing ring, is used for specially cooperating with going between.Finish at lead-in wire, cable socket being opened the lead-in wire sealing by end seal the time immediately, uses end seal circle ordinary production.After having adopted the lead-in wire sealing, just can use same lead-in wire (even steel cable) to draw the cable of different size.
Requirement to the lead-in wire sealing is: 1, sealing is reliable, can work under 1.5MPa pressure, and leakage rate can be controlled within the specific limits (when not leaking fully, pressure is excessive between sealing ring and the lead-in wire, and wearing and tearing are violent, and it is unreliable to use).2, open rapidly, by behind the end seal, arrive before the lead-in wire sealing about 15 at the cable socket of producing? about 0 second, must open sealing device, otherwise product is stuck in here, cause phenomenons such as decortication, fracture, cause shutting down completely.3, operability is good, leaks to be unlikely to spray on one's body the operator.And be simple and easy to use.
Conventional art has following defective and deficiency: general problem of lead sealing equipment existence of 1, using at present is exactly in use, and sealing ring is for once compressed, and these two aspects of the location of sealing ring and the adjusting of seal degree all have problems.2, opening of sealing device: at present the lead sealing equipment of making open basic employing hydraulic drive, be swift in motion, can open in about about 2 seconds, but need a cover hydraulic system, structure is more complicated also.Seldom some thread guide devices employing screw drive are also arranged, opening the lead-in wire sealing by hand, but this mode of operation speed is slower, just can open in about about 10 seconds, the surplus of operating time seldom, and is very high to operating personnel's qualification and the requirement of attentiveness intensity.
Summary of the invention
The present invention mainly is at the above-mentioned technical problem of existing in prior technology, a kind of good sealing effect is provided, opens rubber covered wire vulcanization sealing device rapid, simple in structure, easy and simple to handle.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of rubber covered wire vulcanization sealing device, comprise seal body, offer the through hole that the current supply cable lead-in wire passes through on the seal body, the both sides of through hole are provided with sealing ring, it is characterized in that described sealing ring front end is provided with the adjusting gland, described adjusting gland is bolted to the cover plate inboard by adjusting, described adjusting gland and sealing ring contact position are the orthodrome transition, and patch ends is provided with quick opening device.Comprise the sealing ring positioner in this device, sealing ring compresses the degree adjusting device, fast opening device.The present invention at first compresses adjusting with seal degree to the location of sealing ring and compresses in two steps and realize that so just can install sealing ring earlier in producing the process of preparing, accurately additional leakage is reduced in the location.In use, can in the light of actual conditions regulate the degree that compresses (location that this adjusting does not influence sealing ring compresses) of sealing ring, control corresponding leakage rate.Here the mode that adopts the adjusting gland to move forward and backward realizes, when compressing deficiency, screws the adjusting bolt, gland is moved inward compress sealing ring.When excessively compressing, unscrew the adjusting bolt, the pressure inside utilizing adds the gap between large sealing packing ring and the cable tail, so just can regulate leakage rate.The contact position of regulating gland and sealing ring adopts the orthodrome transition, avoids acute angle cutting sealing circle, and can avoid two kinds of situations like this: 1, sealing ring is cut damage.2, sealing ring sticks into gland, is crowded together when opening, and is difficult to open.
As preferably, described quick opening device has comprised to be driven pressing plate soon and is arranged on the guide ring of opening pressing back-end soon, and described to drive pressing plate soon fixing on the cover board by hold-down nut.By behind the end seal, both can rapidly open lead-in wire sealing in about about two seconds in the cable tail termination, open above-mentioned twice hold down gag simultaneously, and make the cable tail termination, guarantee ordinary production smoothly by this position.Opening device has adopted a kind of quick unfolding mode fast, promptly adopts length, the unequal pressing plate of width, when compacted position, utilizes the length of pressing plate to push down cover plate.When opening, only need revolve pressing plate with spanner and turn 90 degrees, at this moment the width of pressing plate is slightly less than the A/F on the cover plate, and cover plate is just opened under internal pressure automatically.Because cover plate is to be installed on the seal body with hinge, there is certain clearance, in order accurately to enter the opening of cover plate after the cover plate rotation, guide ring has been added in design, the relevant position chamfering of while pressing plate, so just guaranteed that pressing plate and cover plate by design fits, precision maneuver, have guaranteed to open fast.
As preferably, the width of described pressing plate is slightly less than the A/F on the cover plate, and the length of pressing plate is greater than the A/F on the cover plate.
As preferably, be provided with the annulus pressing plate that is used for fixing the sealing ring position between described sealing ring and the cover plate, described annulus pressing plate is fixed on the cover plate inboard by bolt.Adopt an annulus pressing plate to locate and compress sealing ring, simple in structure, easy and simple to handle.
As preferably, described sealing ring adopts the double-layer rubber made.Good sealing effect, manufacturing cost are cheap relatively.
As preferably, described annulus pressing plate is a two halves opposite opened structure.The annulus pressing plate is the two halves opposite opened, pulls down pressing plate and sealing ring when being convenient to open the lead-in wire sealing like this.
As preferably, described adjusting gland is a two halves opposite opened structure.Regulate gland and adopt the two halves opposite opened, pull down when being convenient to open.
Therefore, the present invention has good sealing effect, opens characteristics such as rapid, simple in structure, easy and simple to handle.
