New process of side tank mouth of pressure tank

Abstract

The invention discloses a novel side tank opening manufacturing process for a plastic inner container pressure tank for water treatment. The problem that in an existing manufacturing process of the plastic inner container pressure tank, a side tank opening is hard to form can be effectively solved. According to the technical scheme adopted to solve the technical problem, a metal ring is embedded into a plastic inner container layer, a plurality of threaded holes which are used for achieving fastening are prefabricated in the ring, a prefabricated pressing ring is buckled to the corresponding position outside a fiberglass winding layer, a corresponding number of screw holes and a groove which facilitates tight holding of the fiberglass layer are prefabricated in the pressing ring, screws are used for fastening the metal ring which is embedded into an inner container and the pressing ring which is buckled to the exterior of the winding layer together, in this way, the fiberglass winding layer at the position where a side opening is formed is tightly locked to the part below the pressing ring, and therefore it is guaranteed that the capacity of bearing pressure of the whole tank body cannot be reduced or is reduced slightly when the fiberglass winding layer is cut off at the opening position. In the figures, the numeric symbols are as follows: 4-inner container layer,5-fiberglass winding layer, 6-metal ring, 7-threaded holes, 8-pressing ring, 9-screw holes, 10-fastening screws, 11-O-shaped groove, and 12-holding groove.

Description

[0001] Technical field [0002] The invention relates to a new process for manufacturing a side tank mouth of a plastic liner pressure tank for water treatment, and belongs to the technical field of application of composite materials in water purification treatment equipment. Background technique [0003] At present, most of the pressure tanks used to hold various filter materials in water purification treatment equipment are made of glass fiber reinforced plastic composite materials. The outer surface of the tank is reinforced with a composite material of epoxy resin and glass fiber. On the central axis of the tank, the upper and lower ends of the tank are provided with inlet and outlet tanks, thus making a filter for holding various filters. The pressure tank body of the raw material must be leak-proof and withstand large fluctuations in water pressure. If it is possible to open a side port on this pressure tank at a position deviated from the central axis, which is special...
