High-pressure vacuum thermal shrinkage furnace for corrugated stainless steel hose cladding and corrugated stainless steel hose cladding method

Abstract

The invention relates to a high-pressure vacuum thermal shrinkage furnace and a corrugated stainless steel hose cladding method. The high-pressure vacuum thermal shrinkage furnace comprises a guide rail component, a transmission mechanism, a box body, heat insulation cotton, a liner, a fixing frame component, an electric heating tube component, a clamping mechanism component, a fixing door, an electric box, a guide rail wheel component and a vacuumizing device, wherein the fixing door and the electric box are arranged on the guide rail component; the vacuumizing device and a temperature sensor are arranged on the fixing door; a microprocessor and a conducting electrode plate are arranged in the electric box; the electric heating tube component is arranged on a fixing frame component; the fixing frame component is arranged on the fixing door; and the clamping mechanism component is arranged on the box body. The cladding method comprises the following steps of: intercepting a corrugated stainless steel hose, mounting inserted connecting devices at two ends of the corrugated stainless steel hose, sleeving a polyethylene (PE) thermal shrinkage tube on the corrugated stainless steel hose, sleeving the corrugated stainless steel hose on the electric heating tube component, closing the fixing door in a sealing mode, vacuumizing the furnace body, electrifying the conducting electrode plate, heating the electric heating tube component, and performing heat preservation. The high-pressure vacuum thermal shrinkage furnace is convenient and labor-saving to operate, low in cost and good in effect.

Description

Technical field [0001] The invention relates to a high-pressure vacuum heat shrinking furnace for coating stainless steel corrugated hose and a coating method of stainless steel corrugated hose. Background technique [0002] The stainless steel corrugated hose used for the connection of gas appliances is mainly installed in civil kitchens. There are a large amount of chloride ions in the kitchen, such as oil, salt, sauce, vinegar, detergent, and tap water. The stainless steel corrugated hose is easy to be corroded by chloride ions, causing gas leakage in the gas pipeline. The prior art stainless steel corrugated hose used for connecting gas appliances usually does not have a protective layer or uses a PVC material as a protective layer. However, the PVC material has relatively poor flow properties, is very difficult to process, and has poor bending properties, which greatly limits the scope of application. Summary of the invention [0003] The technical problem to be solved by th...

[0002] Stainless steel corrugated hoses for connecting gas appliances are mainly installed in civilian kitchens. There are a lot of chloride ions in the kitchen, such as oil, salt, sauce, vinegar, detergent, tap water, etc., which contain a large amount of chloride ions. The stainless steel corrugated hose is easily corroded by chloride ions, causing gas pipeline leakage

The stainless steel corrugated hose used for connecting gas appliances in the prior art usually has no protective layer or uses PVC material as the protective layer. However, the flow performance of PVC material is relatively poor, it is very difficult to process, and the bending performance is poor, which greatly limits the scope of application.
