Anticorrosive spacer ring type flange of plate heat exchanger

Abstract

The invention relates to a Distance Ring flange used for a heat exchanger, mounted on a flow-in hole or a discharge hole of a plate heat exchanger and combined with a sensor, capable of preventing erosion caused by fluid passing through the internal of the Distance Ring flange used for a plate heat exchanger, and saving cost and enhancing performance, comprising a metal piece, with an internal made from metal materials and having a hollow cylinder shape, a plurality of sensor insert holes being arranged on the lateral side; a sealing piece made from corrosion resistant rubber materials or synthetic resin, capable of covering the inner column face, the lateral face of the metal piece, and the periphery of the sensor insert hole. The common metal piece used for the Distance Ring flange used for the plate heat exchanger in the invention is not exposed in a corrosion atmosphere, and the lower side of the sensor insert hole is sealed so as to avoid erosion effectively.

Description

technical field [0001] The invention relates to a spacer ring flange for a plate heat exchanger, which is combined with the inlet or outlet of the plate heat exchanger and equipped with pressure and temperature sensors to monitor the state of the fluid, especially a flange made of natural rubber, synthetic Rubber or synthetic resin seals wrap the inner cylindrical surface and side surface of the flange made of structural carbon steel and other materials. Spacer ring flanges for plate heat exchangers. Background technique [0002] A plate heat exchanger is a device that transfers the heat of the high-temperature fluid to the low-temperature fluid by contacting the pipe or plate between the high-temperature fluid and the low-temperature fluid, thereby cooling or heating the fluid. [0003] The above-mentioned plate heat exchanger not only detects the temperature or pressure of the two fluids flowing in or discharged and adjusts the flow rate, but also needs to control the temp...

AI Technical Summary

Problems solved by technology

[0009] In order to solve the problem that the existing materials cannot completely prevent the corrosion of the spacer ring flange and the manufacturing cost is too high, the purpose of the present invention is to provide a low-cost plate heat exchanger with different materials (synthetic rubber) that can completely prevent corrosion. and synthetic resin material) spacing ring flange
