Production process of lined fire hose

Abstract

The invention discloses a production process for fire hoses with linings. The production process is characterized by including braiding a lining tube into a hose blank to form a blank tube according to production specification requirements, treating the blank tube through a process of heat sealing after the length of the braided blank tube is capable of meeting production requirements, cooling the blank tube to obtain a finished product, and finally cutting off the finished product according to required production dimension so as to obtain fire hoses with required lengths. The production process has the advantages that the production process is simple and capable of realizing continuous production, and labor is saved while waste is reduced.

Description

technical field [0001] The invention relates to a production method of a fire-fighting hose, in particular to a production process of a lining-lined fire-fighting hose. Background technique [0002] The fire hose is a hose used to transport high-pressure water or foam and other flame-retardant liquids. At present, the most used fire hoses have rubber liners inside, and the processing technology of fire hoses with liners is as follows: first, according to the needs Cut the braided blank into a certain length, then pull the liner of matching size into the blank, then fill the blank with air and clamp both ends of the blank, and then put the blank into a certain The steam under pressure makes the liner and the billet thermally bonded. This process has the following disadvantages: 1. The clamping parts at both ends of the billet cannot be heated, so the gas bands at both ends need to be cut off, resulting in waste; 2. The liner is pulled in The inside of the blank is more diffi...

[0002] The fire hose is a hose used to transport high-pressure water or foam and other flame-retardant liquids. At present, the most used fire hoses have rubber liners inside, and the processing technology of fire hoses with liners is as follows: first, according to the needs Cut the braided blank into a certain length, then pull the liner of matching size into the blank, then fill the blank with air and clamp both ends of the blank, and then put the blank into a certain The steam under pressure makes the liner and the billet thermally bonded. This process has the following disadvantages: 1. The clamping parts at both ends of the billet cannot be heated, so the gas bands at both ends need to be cut off, resulting in waste; 2. The liner is pulled in The inside of the blank is more difficult, time-consuming and labor-intensive; 3. The outer diameter of the required liner is smaller than the inner diameter of the blank, resulting in poor firmness between the liner and the blank, which affects product quality; 4. The workbench used for processing is relatively large, Large area and high production cost
