(1) When PVC lay flat hose is used and stored, it should avoid falling, collision and heavy pressure, so as to avoid the difficulty of assembly and disassembly caused by deformation.
(2) Before the connection of PVC lay flat hose, the sliding groove and sealing parts should be carefully inspected. If there are sludge and sand grains and other debris, they should be removed in time to prevent difficulties in assembling and disassembling and poor sealing.
(3) When connecting the internal buckle type interface, the claw should be inserted into the chute and then screwed in clockwise direction. When connecting PVC lay flat hose, it is necessary to straighten out the PVC lay flat hose in order to prevent the PVC lay flat hose from twisting and disconnecting itself.
(4) When connecting the plug-in interface, the spring pin of the female interface should be inserted until the sound of the spring pin extending to the slot of the male interface card is heard, so as to ensure the reliability of the connection.
(5) Pay attention to avoid contact with acid, alkali and other chemicals during storage to prevent corrosion of metal parts and deterioration of rubber sealing rings.
