In our agricultural irrigation, the length of our irrigation can not be exactly the length of PVC lay flat hose, especially in agricultural irrigation, which is hundreds of meters, thousands of meters or more. This requires PVC lay flat hose joints to connect PVC lay flat hose operation. Choosing a good PVC lay flat hose joint is also the guarantee to ensure the rapid operation of transportation and drainage.
1. Joints can be divided into plastic joints, aluminium joints, casting joints, die-casting joints and tank joints according to the material. Sizes range from 1.5 inches to 8 inches. The pressure of plastic joint is small and can be used for ordinary irrigation. The pressure of PVC lay flat hose joint increases in turn. The joints are divided into upper and lower parts, which contain rubber pads. When connecting, one hand holds the PVC lay flat hose interface, and inserts the protruding part of the PVC lay flat hose interface into the concave part of one end. The wrist rotates clockwise to make the interface clamp. It can be fastened at the groove, and the PVC lay flat hose interface is connected with clips at both ends.
2. Aluminum alloy joints can be matched with high-pressure PVC lay flat hose. Ground-poured PVC lay flat hose joints are generally matched with clips. Buy matched pressure joints, which are not easy to leak water and make irrigation more labor-saving.
3. Pre-assembly of jacketed pipe joints is an important link, which directly affects the reliability of sealing. The end face of the pipe should be level. After the pipe is sawed, it should be polished smoothly on the grinding wheel and other tools, and the burrs should be removed, cleaned and blown with high-pressure air for reuse.
Because of the working pressure limitation, the length of each PVC lay flat hose is generally prescribed, so we often need the PVC lay flat hose interface to realize the length of PVC lay flat hose. Therefore, in order to work quickly, besides choosing a good PVC lay flat hose, the PVC lay flat hose joints should also be well chosen so as to avoid leakage and bursting in the operation.
