Embodiment Construction

[0017] Such as image 3 , Figure 4 As shown, the glass fiber wound pressure vessel of the present invention includes an inner liner 12 and a threaded joint 11 fixedly connected to the mouth and neck 121 at the top or bottom thereof, wherein:

[0018] The outer surface of the threaded interface 11 is provided with several circumferentially distributed anti-sliding positioning grooves 111 and anti-rotation blind holes 112, and an annular shallow groove 113 is opened on the top;

[0019] The mouth and neck 121 of the liner is wrapped around the threaded joint 11, and the two are welded by concave-convex fit at the junction.

[0020] When tightening the valve body 4 inserted in the threaded interface 11, the sealing ring 3 on the valve body 4 is pressed to tighten the gap between the top surface of the threaded interface 11 and the inner tank, so that the inner tank 12 and the top surface of the threaded interface 11 are tightly sealed. Press it to completely cut off the leakin...

Abstract

A pressure container without leakage is made up of the glass fibres through winding, and has internal container and screw connector with antiskid locating slots and antirotation blind holes. The mouth and neck of internal container and the screw connector for valve are matched in concave-convex mode and then fused together.

Description

technical field [0001] The invention relates to a glass fiber wound pressure vessel and a processing method thereof. Background technique [0002] Such as figure 2 As shown, the existing glass fiber wound pressure vessel 1' is composed of an inner tank 12' and a threaded joint 11' at the top or bottom thereof, and is a pressure vessel for holding water in a demineralized water treatment device. When the threaded joint 11' of the glass fiber (ie FRP) wound pressure vessel is connected to the liner 12', since the sealing ring 3 on the valve body 4 is pressed against the top / bottom surface of the threaded joint 11, its sealing performance is completely It depends on the strength of the fusion between the threaded interface 11 and the inner liner 12 and the integrity of the fusion surface. In the actual use of the pressure vessel 1, as the pressure rises and falls, the entire pressure vessel will expand and shrink slightly. When the welding strength is not ideal or the integri...
