Abstract
The utility model relates to a water pipe seal device, in particular to a seal device used for the ram piston cooling pipe of a novel internal mixer, relating to an outer sleeve and a seal ring; the outer sleeve is fixedly connected with the a pressure cover to form an inner cavity; a slide sleeve is arranged in the inner cavity; a gap is formed between the slide sleeve and the circumference of the outer sleeve; the seal ring is mounted on the contact surface of the slide sleeve and the water pipe; in the water pipe seal device, the outer sleeve is in gap connection with the pressure cover and the water pipe; a plurality of seal rings are used for sealing between the slide sleeve and the water pipe; the slide sleeve can move in the inner cavity formed by the outer sleeve and the pressure cover; the slide sleeve is sealed by the seal ring; because the gap is formed between the slide sleeve and the circumference of the inner cavity, the slide sleeve is enabled to swing along with the water pipe; the threaded connection position of the cooling pipe and the ram piston can not be forced to fracture so that the seal and fracture problems of the ram piston cooling pipe of the internal mixer are solved effectively; the international blank is fulfilled by the water pipe seal device.
Description
One, technical field
The utility model relates to a kind of water pipe sealing device, is a kind of floating weight of banbury mixer cooling water pipe sealing device specifically.
Two, background technology
Banbury is widely used equipment in the rubber industry, the key equipment of stream in tire manufacturing plant especially.Need floating weight that the material that is refined is applied certain pressure during banbury work, the floating weight water flowing cooling of large-scale banbury.As shown in Figure 1, floating weight and charge door border gapped (A among Fig. 1) descends floating weight to be driven by collapsing of sizing material in working order, swings., existing water pipe sealing device such as Fig. 2, fairlead is equipped with overcoat outward, between overcoat and the fairlead sealing ring is housed, and sealing ring seals.Cooling water pipe and fairlead border are very close to each other, can not rock relatively, so the problem that ruptures very easily appear in cooling water pipe and the screw thread place that is connected of floating weight.This problem is prevalent on the machine of domestic and imported, and never is resolved.Water pipe is fracture in a single day, and whole equipment need stop and overhaul, and banbury one stops, and whole production line all will be paralysed, and has a strong impact on production.
Three, summary of the invention
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of novel floating weight of banbury mixer cooling water pipe sealing device is provided, and is simple in structure, effectively avoids the cooling water pipe fracture.
The technical scheme that the utility model is adopted for achieving the above object is: novel floating weight of banbury mixer cooling water pipe sealing device, relate to overcoat and sealing ring, overcoat and gland are fixedly connected to form inner chamber, sliding sleeve is housed in the inner chamber, sliding sleeve and overcoat border are gapped, and sliding sleeve and water pipe contact-making surface are equipped with sealing ring.
Described sliding sleeve and water pipe connect true face multiple-sealed circle are housed.
Between described sliding sleeve and gland and the overcoat sealing ring is housed.
Described sliding sleeve is the black polytetrafluoroethylene (PTFE) sliding sleeve that rockfills.
Gapped between described sliding sleeve and the inner chamber border, this gap is greater than all ring gaps between floating weight and the dog-house.
The utility model water pipe sealing device overcoat is connected with the water pipe gap with gland, seal by the many places sealing ring between sliding sleeve and the water pipe, slide in the inner chamber that overcoat and gland form slidably, and seal by sealing ring, since gapped between sliding sleeve and the inner chamber border, sliding sleeve can be rocked with water pipe, and cooling water pipe can be again because of stressed fracture with the screw thread place that is connected of floating weight, efficiently solve the sealing and the breakage problem of floating weight of banbury mixer cooling water pipe, filled up international blank.
Four, description of drawings:
Fig. 1 is the floating weight structural representation.
Fig. 2 is existing cooling water pipe sealed structural representation.
Fig. 3 is the utility model structural representation.
Five, the specific embodiment:
Novel floating weight of banbury mixer cooling water pipe sealing device as shown in Figure 3, the cooling water pipe 2 outer sealing devices that are equipped with, sealing device relates to overcoat and sealing ring, overcoat 4 is fixedly connected to form inner chamber with gland 6, the black polytetrafluoroethylene (PTFE) sliding sleeve 7 that rockfills is equipped with in activity in the inner chamber, sliding sleeve and water pipe contact-making surface are equipped with three seals circle 3, between sliding sleeve and gland and the overcoat sealing ring is housed, gapped B between sliding sleeve and the inner chamber border, this gap is greater than all ring gap A between floating weight 1 and the dog-house, with respect to existing fairlead 5 gapless structures, water pipe is difficult for stressed jackknifing.
