Abstract
The invention relates to a connecting method for strengthening the sealing connection of pipelines, which mainly solves the problem of poor connection and sealing effect in the pipeline connection in the prior art, and comprises the following steps: 1) preparing the connecting piece and the pipe fitting; 2) Cut and remove the inner layer at one end of the pipe fitting with a cutting tool, the length of the inner layer cut and removed is 0.5 mm to 2.5 mm, and the length of the cut and removed length is not less than the thickness of the ring flange; 3) the The product in step 2 is heated by clamping the heating tool. The heating temperature of the clamping heating tool is 150°C-170°C, and the clamping time is 8s-10s to soften it; 4) Put the pipe fitting through the heated end of step 3 Insert it into one of the connecting parts of the connecting piece and hold it for 5s~7s, so that the outer layer and middle layer on the pipe fitting that have not been cut and removed are embedded in the cavity formed by the annular flange, the annular end surface and the connecting part. The end face of the layer rests on the annular ledge.
Description
technical field [0001] The invention relates to a connection method for a connecting piece that strengthens the sealing connection of pipelines. Background technique [0002] A pipe connector is a component used to connect a water pipe, generally referred to as a water pipe joint. According to the materials used, it can be divided into plastic pipe connectors and metal pipe connectors, which are usually used in conjunction with water pipes of the same material. Most of the metal pipeline connectors sold on the market are connected by threads, and a small part is connected by external auxiliary ferrules. Due to the use of metal pipeline connectors, which are expensive, poor in corrosion resistance, easy to rust, and easy to pollute water sources, they are gradually replaced by plastic pipeline connectors. The connection of plastic pipeline connectors is usually through the connection with the water pipe. After applying glue, insert the water pipe into the pipe connector to ...
