Description

Clamping connection type glass fiber reinforced plastic pipeline

Technical Field

The invention relates to the technical field of glass fiber reinforced plastic, in particular to a clamping type glass fiber reinforced plastic pipeline.

Background

The glass fiber reinforced plastic pipeline is a light, high-strength and corrosion-resistant nonmetal pipeline. The glass fiber with resin matrix weight is wound on a rotating core mold layer by layer according to the technological requirement, and quartz sand is uniformly paved among the fibers at a long distance to serve as a sand inclusion layer. The pipe wall structure is reasonable and advanced, the function of materials can be fully exerted, the rigidity is improved on the premise of meeting the use strength, and the stability and the reliability of the product are ensured. The glass fiber reinforced plastic sand inclusion pipe has the advantages of excellent chemical corrosion resistance, light weight, high strength, no scaling, strong shock resistance, long service life compared with the common glass fiber reinforced plastic pipeline, low comprehensive manufacturing cost, quick installation, safety, reliability and the like, and is accepted by the majority of users. In the process of laying the pipeline, the glass fiber reinforced plastic pipeline is usually connected in a flange butt joint mode, the bolt screwing time is long, and the working efficiency is not high.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the technical problem that the connection of the traditional glass fiber reinforced plastic pipeline in a flange butt joint mode is long in time consumption is solved.

The invention provides a clamping type glass fiber reinforced plastic pipeline which comprises a first glass fiber reinforced plastic pipeline, a second glass fiber reinforced plastic pipeline and a clamping ring; a first flanging is arranged at one end, which needs to be connected, of the first glass fiber reinforced plastic pipeline, and a plurality of notches are formed in the first flanging;

a second outward flanging is arranged at one end, which needs to be connected, of the second glass fiber reinforced plastic pipeline;

the clamping plate is connected with the second flanging in a clamped mode, and the clamping plate is provided with a plurality of clamping blocks corresponding to the notches and connected with the first flanging in a clamped mode.

First FRP pipe and second FRP pipe pass through the mode fixed connection of the first flanging of snap ring joint and the second flanging, simple structure, and the operation is swift, and the second steel pipe can also rotate wantonly moreover, and the practicality is strong.

Further, the second outer flanging is coated with a sealing ring; the sealing ring is clamped on the second outward turning edge in a coating mode and is not easy to fall off.

Furthermore, the clamping plate is connected with an elastic sheet pointing to the inside of the clamping ring. When the first glass fiber reinforced plastic pipeline and the second glass fiber reinforced plastic pipeline are connected, the elastic sheet is deformed by pressure difference and generates restoring force, so that the first glass fiber reinforced plastic pipeline and the second glass fiber reinforced plastic pipeline are pressed.

Furthermore, the fixture block is provided with a positioning pin connected through a spring, and the first flanging is provided with a pin hole corresponding to and clamped with the positioning pin. The cooperation effect of locating pin and pinhole makes fixture block and first flanging joint back can not take place the rotation because of vibrations and lead to first FRP pipe way and second FRP pipe way to break away from.

Furthermore, one end of the positioning pin, which is close to the first glass fiber reinforced plastic pipeline, is provided with a pull ring. When the positioning pin is detached, the positioning pin can be separated from the pin hole only by pulling the pull ring, the operation is convenient, and the pull ring also plays a role in positioning the positioning pin, so that the positioning pin moves between the pull ring and the fixture block.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

As shown in figure 1, the invention is a clamping type glass fiber reinforced plastic pipeline, which comprises a first glass fiber reinforced plastic pipeline 1, a first glass fiber reinforced plastic pipeline 2 and a clamping ring 3; as shown in fig. 6 and 7, a first outward turning edge 11 is arranged at one end of the first glass fiber reinforced plastic pipeline 1 to be connected, and the first outward turning edge 11 is provided with three notches 12;

as shown in fig. 8, a second flanging 21 is arranged at one end of the first glass fiber reinforced plastic pipeline 2 to be connected, and the second flanging 21 is coated with a sealing ring 4;

as shown in fig. 4 and 5, one end of the snap ring 3 is provided with a snap plate 31 which is clamped with the second flanging 21, and the end of the snap plate 31 is connected with an elastic sheet 33 which points to the inside of the snap ring 3; the other end of the clamping ring 3 is provided with three clamping blocks 32 which correspond to the notches 12 and are clamped with the first flanging 11;
