Description
Technical Field
The utility model relates to a fiber reinforced cement pipe, especially a fiber reinforced cement is seal structure for pipe.
Background
The plant fiber reinforced cement pipe needs to be connected with the end parts of two cement pipes through a joint when being installed, the conventional joint structure at present consists of a cylindrical sleeve and two annular sealing rings, wherein the annular sealing rings are installed in grooves of the inner circle of the sleeve, and the end parts of the cement pipes are sleeved into the sleeve and are mutually buckled with the annular sealing rings when being connected, so that the sealing effect is realized.
And in order to improve the leakproofness of ring packing after connecting, the interior circle diameter of present ring packing can slightly be lighter than the external diameter of cement pipe when the design, and the cement pipe needs open ring packing and accomplish the connection when inserting promptly, and then utilizes ring packing's deformation and resilience effect to guarantee the compactness of its laminating. Although the connecting structure can achieve the required sealing effect, the installation and connection difficulty of the cement pipe can be correspondingly increased, namely the cement pipe is easy to cause collision interference and friction displacement of the annular sealing ring when the annular sealing ring is inserted into the cement pipe, so that an installer needs to repeatedly operate when the cement pipe is connected, and the working strength of workers is increased.
In addition, in order to accelerate the insertion efficiency during the actual installation of the cement pipe, the end part of the cement pipe is ground, namely the cement pipe and the annular sealing ring are removed at the position with large interference. Although the installation efficiency can be improved by the polishing mode, a gap is easily formed between the corresponding cement pipe and the annular sealing ring after polishing, so that the sealing effect of the annular sealing ring on the cement pipe is reduced.
Therefore, the existing fiber reinforced cement pipe cannot be rapidly inserted into the sealing ring under the condition of ensuring the sealing effect.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a seal structure for fiber reinforced cement pipe. The quick plug-in connection with the sealing ring can be realized under the condition of ensuring the sealing effect.
The technical scheme of the utility model: the sealing structure for the fiber reinforced cement pipe comprises pipe bodies, wherein adjacent pipe bodies are mutually connected through a connecting sleeve, the inner side of the connecting sleeve is connected with a sealing washer through a groove, the inner circle of the sealing washer extends to the outer side of the groove and is mutually attached to the outer wall of the pipe body, and a pressing ring mutually attached to the sealing washer is arranged on the outer wall of the pipe body; the cross-section appearance of seal ring is trapezoidal, and the medial surface of seal ring is the arcwall face.
In the sealing structure for the fiber reinforced cement pipe, the inner side surface of the sealing washer is simultaneously attached to the outer wall of the adjacent pipe body.
In the sealing structure for the fiber reinforced cement pipe, the end part of the pipe body is provided with the arc-shaped sealing opening, and the sealing opening and the sealing washer are mutually attached to each other at the arc-shaped surface.
In the sealing structure for the fiber reinforced cement pipe, the end part of the pipe body is provided with the positioning step, the positioning step is buckled with the connecting sleeve, and the clamp ring is positioned on the positioning step.
Compared with the prior art, the utility model can extrude the side walls at the two sides of the sealing washer through the compression ring after the pipe body is inserted through the matching of the pipe body and the compression ring, so that the thickness of the sealing washer is increased after the sealing washer is extruded and deformed, and the laminating tightness between the sealing washer and the groove and between the sealing washer and the pipe body is effectively improved; under the cooperation, the pipe body can be extruded and deformed after the sealing washer is inserted into the pipe body, so that the problem of interference between the sealing washer and the pipe body at the edge position is effectively solved, and the pipe body is quickly inserted into the sealing washer; the shape of the sealing washer is limited, and the sealing port at the end part of the tube body is arranged, so that the contact area between the sealing washer and the sealing port after being extruded can be further increased, and the sealing effect of the sealing washer is further improved; through the lock structure to location step and adapter sleeve, can also carry on spacingly to the inserted position of body, when location step and adapter sleeve were buckled completely promptly, the realization of explanation clamp ring was to seal ring's stable extrusion. Therefore, the utility model discloses can realize pegging graft fast with the sealing washer under the condition of guaranteeing sealed effect.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The labels in the figures are: the pipe comprises a pipe body 1, a connecting sleeve 2, a sealing washer 3, a compression ring 4, a sealing opening 101, a positioning step 102 and a groove 201.
Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. The sealing structure for the fiber reinforced cement pipe is shown in figure 1, and comprises pipe bodies 1, wherein adjacent pipe bodies 1 are mutually connected through a connecting sleeve 2, the inner side of the connecting sleeve 2 is connected with a sealing washer 3 through a groove 201, the inner circle of the sealing washer 3 extends to the outer side of the groove 201 and is mutually attached to the outer wall of the pipe body 1, and a pressing ring 4 mutually attached to the sealing washer 3 is arranged on the outer wall of the pipe body 1; the cross-sectional shape of the sealing washer 3 is trapezoidal, and the inner side surface of the sealing washer 3 is an arc-shaped surface.
The inner side surface of the sealing washer 3 is simultaneously attached to the outer wall of the adjacent pipe body 1.
The tip of body 1 is equipped with curved sealing port 101, and sealing port 101 and seal ring 3 are laminated each other in arcwall face department.
