Composite end enclosure and processing process

Abstract

A composite end enclosure belongs to the technical field of central air conditioners. An end enclosure body is arranged on a vessel flange of the end enclosure, valve seats and rubber gaskets are arranged on the end enclosure body, a water inlet connector and a water outlet connector are arranged on the end enclosure body, and thereby the integrated composite end enclosure is formed. A processing process for the composite end enclosure includes the following steps: mold preparation, reinforcing material laying, vacuumization and closing of an upper mould and a lower mould, vacuumization, glue preparation, resin impregnation, curing, demoulding, trimming, post-trimming processing, inspection and warehousing. The invention has the advantages that: firstly, since the water inlet connector, the water outlet connector, the end enclosure and the vessel flange are formed in one step, the production efficiency is increased, metal material is saved, and the production cost is reduced; secondly, after connector flanges are removed from the product and locknuts and the gaskets are added on the product, the production cost is reduced, and the corrosion resistance, the tightness and the part replacement convenience are enhanced; thirdly, the processing process is simplified, the production period is shortened, and the working efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of central air conditioning. Background technique [0002] With the continuous and rapid growth of my country's national economic construction and the continuous improvement of people's living standards in our country, the demand for central air-conditioning is increasing. In order to meet the great pressure, it is necessary to adopt energy-saving and high-efficiency technologies to gradually solve this problem. The ocean is a huge renewable energy pool, which is very suitable as a low-temperature heat source for water source heat pumps. After years of experimental research and research by our company, the seawater source heat pump air conditioning system has been applied in areas where fresh water is scarce and seawater is abundant. However, due to the high salt content of seawater, which mainly contains sodium chloride, magnesium chloride and a small amount of sodium sulfate and calcium sulfate, seawater i...

Problems solved by technology

[0005] The purpose of the present invention is to provide a composite material head and processing technology to solve the poor sealing effect of the prior art, which is prone to seawater leakage; The flange is formed at one time, and the flange is hand-laid on the connecting pipe after it is needed; it is not conducive to environmental and labor protection, unstable quality, low pressure resistance, and low output; the time of seawater corrosion resistance is short, seawater leakage occurs, and it is difficult to replace the valve seat.
