Abstract
The utility model discloses the sealing structure of a cable interface for a pressure vessel, which comprises a sealing member arranged in the cable through hole of a cable installation body, and a spiral plug. The spiral plug is provided with an intermediate hole used for at least one bundle of cables to pass through. The cable through hole is provided with an internal thread matched with the spiral plug. According to the utility mode, the sealing member in the cable through hole is deformed so as to tightly squeeze cables through screwing the spiral plug. Therefore, the gaps among cables are eliminated and the sealing performance of the installation part of cables is improved.
Description
Technical field
The utility model relates to the cable mounting technique, relates in particular to a kind of pressurized container cable interface sealing configuration with high sealing performance, can be adapted to the strict pressurized container of various operating conditions.
Background technique
The safe handling standard of pressurized container is comparatively strict, generally needs all kinds of parameter monitorings in the online detected pressures container, need draw some cables for this reason and supply transmission signal.In the cable interface sealing configuration of existing pressurized container, generally adopt material such as seal ring to seal, but the part distortion when adopting common O type circle is less relatively, makes the sealability of cable installation position dislike not enough slightly, there is bigger potential safety hazard undoubtedly in this.
The model utility content
To the defective of existing technology, the purpose of the utility model is to provide a kind of pressurized container cable interface sealing configuration, can effectively improve the sealability of cable installation position.
For solving above technical problem; The technological scheme of the utility model is: a kind of pressurized container cable interface sealing configuration; Comprise sealed member, be positioned at cable through hole on the cable fixing body, also comprise plug screw; Said plug screw offers and is conducted to less the intermediate hole that a branch of cable passes through, and said cable through hole is provided with and the supporting internal thread of said plug screw.
More excellent ground, said cable through hole is a ladder-type cable through hole.
More excellent ground, a thicker end of said ladder-type cable through hole accommodates elastomer, as with the supporting said sealed member of said cable through hole, offer on the said elastomer and be conducted to less the intermediate hole that a branch of cable passes through.
More excellent ground, said elastomer is a rubber pad ring.
More excellent ground, said cable fixing body is the flat cover of pressurized container, and said flat cover places the CONCENTRIC REDUCER front of pressurized container, and said CONCENTRIC REDUCER is installed on the flange of front and back.
Compared with prior art; The utility model pressurized container cable interface sealing configuration is provided with plug screw; In the process of its screw-in cable through hole, will make sealed member be out of shape; This just helps to improve the sealability of pressurized container cable interface sealing configuration, has eliminated potential safety hazard on largely, can satisfy pressurized container etc. to the have relatively high expectations seal request of occasion of operating conditions.
Description of drawings
Fig. 1 is the schematic representation of the utility model pressurized container cable interface sealing configuration one preferred embodiment;
Fig. 2 is that pressurized container cable interface sealing configuration shown in Figure 1 is applied in the schematic representation on the pressurized container.
Embodiment
The thought of the utility model pressurized container cable interface sealing configuration is, plug screw is set, and adopts screw-thread fit between itself and the cable through hole, makes its distortion through the crush seal parts, effectively improves the sealability of cable installation position.
In order to make those skilled in the art understand the technological scheme of the utility model better, the utility model is done further to specify below in conjunction with accompanying drawing and specific embodiment.
Referring to Fig. 1, the schematic representation of expression the utility model pressurized container cable interface sealing configuration one preferred embodiment.This pressurized container cable interface sealing configuration comprise the cable through hole 4 that is opened on the cable fixing body 3, with supporting sealed member 5 and the plug screw 2 of cable through hole 4; This plug screw 2 offers and is conducted to less the intermediate hole that a branch of cable 1 passes through; This cable through hole 4 is provided with the internal thread supporting with plug screw 2, forms screw connection structure between itself and the plug screw 2.
As shown in Figure 1, cable through hole 4 is a ladder-type cable through hole, and its thicker end is provided with the supporting sealed member 5 of elastomer conduct and cable through hole 4; Offer on this elastomer and be conducted to less the intermediate hole that a branch of cable 1 passes through, specifically can adopt the structure of rubber pad ring.
Pass through cable 1 during use earlier; Again plug screw 2 is screwed in the cable through hole 4; Make sealed member 5 distortion and and form drive fit between the cable 1; This just helps to improve the sealability of pressurized container cable interface sealing configuration, has eliminated potential safety hazard on largely, is adapted to the occasion that pressurized container etc. is had relatively high expectations to operating conditions especially.
Referring to Fig. 2, represent the application example of above-mentioned pressurized container cable interface sealing configuration on pressurized container.Cable fixing body 1 wherein is the flat cover 6 of pressurized container, and it places the front of the CONCENTRIC REDUCER 8 of pressurized container, and CONCENTRIC REDUCER 8 is installed on forward flange 7 and the rear flange 9.Like this through the screwing of plug screw 1, just can oppress rubber pad ring and deform, thus jam-packed cable 1, the gap of eliminating cable 1 and rubber pad ring finally forms good sealing; Especially, wherein the amount of screwing of plug screw 2 can be controlled the degree of sealing, helps to expand the application area of the utility model.
Only be the preferred implementation of the utility model below, should be pointed out that above-mentioned preferred implementation should not be regarded as the restriction to the utility model, the protection domain of the utility model should be as the criterion with claim institute restricted portion.For those skilled in the art, in spirit that does not break away from the utility model and scope, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
