Abstract
The invention relates to a cable seal module applied to various industrial fields. Daub and a gland head can not satisfy waterproof, fireproof and blast-proof requirements better in actual use, which is caused by the following reasons that the use of the daub relies on the proficiency level of a worker; the gland head needs to be arranged in a two-side way and also needs a large wrenching space while installing, a cable needs to be drawn out when maintaining, , and a thread is likely to loose after a long time use; and in addition, the current module seal technology is a symmetrical two-half structure generally, and a parting plane is linear (lying in being capable of stretching production) and leads to a linear waterproof and fireproof gap. Therefore, the seal can be ensured only by huge pressure, and the module is easy to fall off during installation and use, and meanwhile, the linear gap is not allowed in an explosion-proof occasion. The invention puts forwards a new solution aiming at the problems.
Description
Technical field
The present invention relates to cable, the technology of sealing such as pipeline.
Background technology
Existing cable sealing module two halfbody joint places up and down generally all is the plane, for fire prevention and waterproof, and the demanding occasion of flame proof, open under bigger pressure easily in the slit of straight line, causes the inefficacy of function; Especially in the occasion of Exd flame proof requirement, the slit of straight line is unallowed; And the slit of straight line needs reeded requirement to satisfy to creepage gap.And the characteristic of module is single, and is not good in occasion results of use such as fire-proof shields.Simultaneously, in the occasion of fire proof seals such as building requirement more than four hours, all adopt organic material to be difficult to satisfy the fireproof requirement.
Summary of the invention
At the defective that exists in the above-mentioned prior art, technical problem to be solved by this invention is to propose new module sealing structure, thereby under the constant situation of cost, proposes to solve the scheme of these defectives.
Description of drawings
Fig. 1 be seal modules of the present invention explosive view;
Shown in Figure 2 is front view of the present invention and end view;
Embodiment
Below in conjunction with description of drawings embodiments of the invention are described in further detail, but present embodiment is not limited to the present invention, every employing analog structure of the present invention and similar variation thereof all should be listed protection scope of the present invention in.
Cable sealing module explosive view as shown in Figure 1: two skeletons 1 that dig out a semicircular cavity in the middle of a side of cuboid involute a circular cavity.Skeleton is made up of several sections, is respectively fire prevention dilation or fire prevention part 3, elastic water-proof driving fit part 4, EMC masked segment 5, certainly skeleton 1 also can be wherein two parts or single part formation, makes up according to concrete actual needs, and the position of each several part can be changed.Each skeleton 1 cavity inner surface is bonded with semi-cylindrical envelope curve layer 2.Envelope curve layer 2 can be one or several layers of formation; Can bond together between envelope curve layer 2 each layer, also can stick on together; Every layer of the envelope curve layer can be constituted by three parts, be respectively fire prevention dilation or fire prevention part 6, elastic water-proof driving fit part 7, EMC masked segment 8, certainly the envelope curve layer also can be wherein two parts or single part formation, make up according to concrete actual needs, the position of each several part can be changed.Each layer or the part of the various piece of skeleton 1 or envelope curve layer 2 can have elasticity, the high temperature expansion characteristics, or have fire performance, perhaps have shielding character, perhaps the combination of several characteristics.
As shown in Figure 2 be the front view and the end view of the another one example used of the present invention: see from the side, there are projection and depression 9 in the side of two skeletons (perhaps skeleton and envelope curve layer), the projection of two skeletons and depression 9 corresponding fitting tightly when the driving fit, two skeletons 1 can be symmetries or asymmetrical, antisymmetric up and down.Projection and depression 9 can be circular, triangle, the trapezoidal various forms that waits.The horizontal and vertical of each envelope curve layer can have projection or depression, and corresponding skeleton has depression or projection, thereby makes the production assembling convenient.
