Disclosure of Invention

The utility model aims at providing a PVC electric power pipe with seal structure for solving between pipeline and the pipeline be connected the untight problem of sealing.

In order to achieve the above purpose, the utility model provides a following technical scheme: comprises a pipeline body; the pipeline sealing device is characterized by further comprising a sealing mechanism for sealing and connecting the pipeline body and a connecting mechanism for fixing the pipeline body and the pipeline body.

Further preferably, the sealing mechanism comprises a sealing element, a limiting table arranged on the sealing element and sealing rings arranged on two sides of the limiting table; the pipeline body is provided with an annular groove matched with the sealing ring.

Further preferably, a plurality of protrusions which are obliquely arranged are arranged on two sides of the sealing ring.

Further preferably, the connecting mechanism comprises connecting plates arranged at two ends of the pipeline body and bolts arranged on the connecting plates and used for fixedly connecting the pipeline body and the pipeline body.

The utility model has the advantages that: through sealing mechanism's setting, after annular groove and the sealing washer that will set up on the pipeline body aim at, cup joint the pipeline body on the sealing washer along the direction of protruding slope, at the in-process that cup joints, the pipeline body produces inside extrusion force to the arch, thereby order about the arch because receive the extrusion force and inwards compress, thereby increase the compactness of being connected between annular groove and the sealing washer, simultaneously through a plurality of bellied settings, form multistage sealed, improve sealed effect, and make pipeline body and sealing mechanism's being connected difficult for breaking away from through the close fit of annular groove and sealing washer, and simultaneously, the guide effect has been played in being connected of pipeline body and sealing mechanism, easy operation is convenient and labour saving and time saving.

Through coupling mechanism's setting, pass through bolted connection at the connecting plate of pipeline body both ends with setting up, played spacing fixed action to connecting between the pipeline body, connecting the in-process that carries out the fastening between the pipeline body through the bolt, make the pipeline body that cup joints at sealing mechanism both ends connect along the direction of protruding slope for be connected between pipeline body and the pipeline body inseparabler.

Detailed Description

The PVC power tube with a sealing structure according to the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1 to 4, a PVC power pipe having a sealing structure includes a pipe body 1; the pipeline sealing device is characterized by also comprising a sealing mechanism 2 which plays a role in sealing connection between the pipeline body 1 and a connecting mechanism 3 which plays a role in fixing the connection between the pipeline body 1 and the pipeline body 1; the sealing mechanism is arranged between the two pipeline bodies 1 through the arrangement of the sealing mechanism 2, and the pipeline bodies 1 are connected more tightly through the close fit of the pipeline bodies 1 and the sealing mechanism 2; through the setting of coupling mechanism 2, play spacing fixed action to being connected between pipeline body 1 and the pipeline body 1.

Further, the sealing mechanism 2 comprises a sealing element 21, a limit table 24 arranged on the sealing element 21, and sealing rings 22 arranged on two sides of the limit table 24; the pipeline body 1 is provided with an annular groove 12 matched with the sealing ring 22; through the setting of sealing mechanism 2, install sealing washer 22 in annular groove 12, through the cooperation of sealing washer 22 with annular groove 12 for the connection between the pipeline body 1 is inseparabler.

Furthermore, a plurality of obliquely arranged bulges 23 are arranged on two sides of the sealing ring 22; through the setting of a plurality of archs 23, at the in-process of connecting pipeline body 1, pipeline body 1 produces the extrusion force to arch 23, thereby order about arch 23 owing to receive the extrusion force after compression, the connection compactness between annular groove 12 and the sealing washer 22 has been increased, form multistage sealed, sealing effect has been improved, and through the inseparable cooperation of annular groove 12 and sealing washer 22, make pipeline body 1 be difficult for breaking away from with sealing mechanism 2's being connected, simultaneously, the arch that is the slope setting has played the guide effect to being connected of pipeline body 1 and sealing mechanism 2.

Further, the connecting mechanism 3 comprises connecting plates 31 arranged at two ends of the pipeline body 1 and bolts 32 arranged on the connecting plates 31 and used for fixedly connecting the pipeline body 1 and the pipeline body 1; through coupling mechanism 3's setting, will set up the connecting plate 31 at pipeline body 1 both ends and connect through bolt 32, play spacing fixed action to connecting between the pipeline body 1, connect the in-process that carries out the fastening between the pipeline body 1 through bolt 32, make the pipeline body 1 who cup joints at 2 both ends of sealing mechanism connect along the direction of protruding 23 slopes for be connected between pipeline body 1 and the pipeline body 1 inseparabler.

The utility model discloses a use: after the operator aligns the annular groove 12 of the pipe body 1 with the packing 22, the packing 22 of the sealing member 21 is inserted into the annular groove 12, and then the operator attaches another pipe body 1 to the packing 22 on the other side of the stopper 24 in the same manner.
