Glass fibre winding water container

Abstract

The invention discloses a fiberglass coated water container which includes an inner liner, a thread interface fixedly connected at the neck of the top part or the bottom part of the inner liner as well as a fiberglass coated layer coated outside the inner liner to carry out pro+tection on the inner liner. An annular embedding structure used for embedding and fixing the end part of the fiberglass coated layer is correspondingly arranged on the outer wall of the thread interface. The fiberglass coated water container has a simple structure, is conveniently processed and manufactured, can reliably run for a long period and can effectively solve the hidden trouble problem existed in peeling off between the inner liner and the coated layer.

Description

technical field [0001] The invention relates to a pressure vessel, in particular to a glass fiber wound water vessel working under a certain pressure. Background technique [0002] Such as figure 2 As shown, the existing glass fiber-wound water container is composed of an inner tank 3, a threaded joint 2 on the top or bottom thereof, and a glass fiber winding layer 4 wound outside the inner tank 3. It is a water treatment device for treating water. water container. The liner is anti-leakage, but the pressure bearing capacity is low, and the glass fiber wound shell protects the liner from deformation and damage under internal pressure. In the actual use of the water container, with the rise and fall of the pressure, the entire pressure container will expand and shrink slightly. When the bonding strength between the winding layer and the inner tank does not reach the ideal situation or after the pressure container has been working for a long time, The winding layer will be ...
