Abstract

The fire hose consists of hose blank of woven fiber and composite waterproof layer in the inner wall of the hose blank, the composite waterproof layer is made of PVC plastic, and the hose blank has warp yarn of polyester thread and weft of polypropylene thread. The making process of the fire hose includes weaving the warp yarns and weft yarns to form compact tubular hose blank, passing the hose blank through extrusion mold of plastic pipe forming machine to coat the hose blank with composite PVC layer, cutting the hose into required length, and turning the inner layer of the hose into the outer layer. The fire hose has high combination strength between the hose blank and the composite layer, low cost and long service life.

Description

A kind of fire hose and manufacture method thereof

Technical field

The present invention relates to extinguisher, is the improvement to fire hose and manufacture method thereof.

Background technology

Existing fire hose is made up of the pipe of fibrage and the waterproof composite bed of pipe inwall, waterproof composite bed wherein adopts elastomeric material, its manufacture method is that fibrage is become into the tubular pipe, cutting into needs length, raw rubber is made the socket of respective length, diameter is less than the pipe internal diameter, rubber tube is placed in the pipe, one end is blocked, in the rubber socket of the other end, inject high temperature and high pressure gas, rubber tube is expanded, be close to the pipe inwall, the water band is made in the typing of the vulcanization of rubber simultaneously.

Because the adhesion of rubber waterproof composite bed and pipe is little, easily to peel off, service life is short.If rubber tube starts a leak in the composite sulfuration process in addition, can't repair, cause and scrap, quality is difficult for guaranteeing in the production process.

Summary of the invention

The object of the invention is to provide the bond strength height of a kind of waterproof composite bed and pipe, and the fire hose of long service life and manufacture method thereof are beneficial to use, and improve the quality of production.

The solution of the present invention is: a kind of fire hose, to form by the pipe of fibrage and the waterproof composite bed of pipe inwall, and described waterproof composite bed adopts the PVC plastics.

The warp of described pipe adopts polyester thread, and parallel adopts the polypropylene fibre line.

Its manufacture method is, earlier warp, parallel is woven into the tubular pipe, and by in the extrusion die of plastic pipe machine, the PVC composite bed is made the water band on the pipe outer wrapping with pipe, cut into need length after, the internal layer of water band turned over to skin get final product.

Described tubular pipe middle longitude and parallel are woven into the intensive cloth tube of atresia seam.

Advantage of the present invention is: compound with pipe in extrusion die when under high temperature, high pressure, being in a liquid state owing to PVC, and the bond strength height; In addition, in manufacture process,,, guaranteed quality because it at skin, can be repaired easily if composite bed starts a leak; Add that the PVC material is lower than rubber cost, fire hose of the present invention has that cost is low, the advantage of long service life.

The specific embodiment

The present invention will be further described according to embodiment below.

The fire hose of embodiment adopts soft PVC (PVC) as the waterproof composite bed.Because the terylene heatproof is than polypropylene fibre height, warp is higher than parallel on the braiding pipe well, more outstanding, contact with the core rod of extrusion die, so the warp of pipe adopts polyester thread, parallel adopts the polypropylene fibre line, because of the polypropylene fibre line lighter, strength ratio polyester thread height can reduce use amount in actual the use, so not only can reduce cost but also can increase the pressure that fire hose can bear.

The manufacture method that embodiment adopts is, earlier warp, parallel is woven into the tubular pipe, and tubular pipe middle longitude and parallel are woven into the intensive cloth tube of atresia seam.

By in the extrusion die of plastic pipe machine, pipe is enclosed within on the core rod of extrusion die, and makes it at the uniform velocity mobile with pipe.

Temperature adopts 200 ℃ in the die cavity of extrusion die, makes the PVC pellet melt the back and evenly wraps up outside pipe, forms composite bed and makes the water band.

After the water band cuts into and needs length, its internal layer turned over to skin promptly make finished product.

Claims

1. a fire hose is made up of the pipe of fibrage and the waterproof composite bed of pipe inwall, it is characterized in that: described waterproof composite bed adopts the PVC plastics.

2. fire hose according to claim 1, it is characterized in that: the warp of described pipe adopts polyester thread, and parallel adopts the polypropylene fibre line.

3. fire hose as claimed in claim 1 or 2, its manufacture method is: earlier warp, parallel are woven into the tubular pipe, by in the extrusion die of plastic pipe machine, the PVC composite bed is made the water band on the pipe outer wrapping with pipe, cut into need length after, the internal layer of water band turned over to skin get final product.

4. the manufacture method of fire hose as claimed in claim 3 is characterized in that: described tubular pipe middle longitude and parallel are woven into the intensive cloth tube of atresia seam.
