Description

Fire-fighting rubber pipe

Technical Field

The utility model relates to a fire engineering field especially relates to fire control facility's adapting unit.

Background

The fire-fighting facilities are system engineering which is necessary for various places such as offices, businesses, enterprises, public welfare projects, residential districts and the like. In order to improve the fire-fighting quality of the facility, prolong the service life of the facility, ensure the continuous use safety of the facility and connect and match the fire-fighting pipe with better normal use performance with the fire-fighting apparatus.

The fire fighting pipe is installed at the joint of various fire fighting appliances and is a key elastic element connected between fire fighting equipment. PVC fire control pipe that uses in the tradition, resistant time, withstand voltage, ageing resistance can not satisfy the fire control facility long-term use far away and exposed demand, and the certain degree has brought the hidden danger for fire control safety.

Disclosure of Invention

In order to overcome not enough among the prior art, the utility model provides a fire-fighting rubber tube has that weatherability is good, bearing pressure is big, the bending capability is strong, cut out advantages such as according to the specification wantonly, and the product is tired ageing resistance is excellent moreover, can satisfy fire-fighting equipment continuous use and exposed needs.

In order to achieve the above purpose, the utility model adopts the following technical proposal; the utility model discloses a fire-fighting rubber tube, which comprises a tube core, an inner layer, a weaving layer and an outer layer, wherein the tube core is positioned at the innermost side of the rubber tube; the inner layer is tightly coated outside the tube core and is an ethylene propylene diene monomer mixed rubber material layer extruded with the tube core; the braided layer is coated outside the inner layer and is a braided layer of nylon wire multi-strand slurry; the outer layer is coated outside the braided layer and is a ternary ethylene propylene rubber material layer formed by constant-temperature cooling and extrusion molding.

The inner layer is extruded by selecting a machine core and a shell with a core according to specifications by adopting ethylene propylene diene monomer rubber compound; the weaving layer weaves the extruded inner layer blank with the core with pulp; the outer layer adopts a braided layer with good slurry, the braided layer is dried by an oven, the core and the shell of the outer layer are selected, the temperature is controlled well, and ethylene propylene diene monomer mixed rubber is used for extrusion.

Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has been obtained: firstly, the ethylene-propylene-diene monomer rubber material is selected, has strong weather resistance, and does not crack after being exposed to the sun for more than three years at normal temperature; secondly, the inner layer with core is extruded and braided in multiple strands, so that the bearing pressure of the fire-fighting hose is enhanced, and the bursting pressure is 5 MPa; thirdly, the braided layer is subjected to slurry dragging twice, so that the bonding strength between the inner and outer layer rubber materials and the braided layer is promoted, and the follow-up force of the rubber slurry is improved; fourthly, the inner layer, the woven layer and the outer layer of the rubber tube are extruded by a novel cold feeding extruder, and are cooled at constant temperature to control, so that the compactness of the rubber material of the product is effectively improved, and the rubber tube has good bending and coiling elasticity and long service life.

Detailed Description

As shown in figures 1 and 2, the ethylene propylene diene monomer rubber fire-fighting pipe of the utility model. The inner layer is made of ethylene propylene diene mixed rubber material, the core and the shell are selected according to specification requirements, the mouth shape temperature is controlled to be about 85 ℃, and the body temperature is controlled to be about 65 ℃, and the inner layer is extruded and molded through an extruder. The weaving layer is a blank of the extruded inner layer with the core, and the weaving layer is woven with pulp by a pulp passing boat, and the pulp soaking time is not more than 10 minutes. The joints are not overlapped, the spinning is sparse and uniform, and no suspension wire or jumper wire is arranged. After the outer layer, namely the inner layer, is woven with the pulp, the pulp is dragged twice, and then the outer layer, namely the inner layer, enters an oven to be dried, wherein the temperature of the oven is controlled to be about 180 ℃, and the speed is controlled to be about 10 m/min. After drying, the outer layer core and the outer shell are selected correctly, the temperature of the machine head and the machine body is controlled well, and the tube blank is extruded according to the specification requirement, and the thickness and the outer diameter of the tube blank tube wall meet the standard. And cutting the cooled pipe according to the requirements of fire-fighting equipment, and forming a final finished product after the pipe is qualified through inspection.

The foregoing is illustrative of the preferred embodiments of the present invention and is not to be construed as limiting the invention in any way. Therefore, under the prerequisite that does not deviate from the utility model discloses structural principle, a plurality of specifications and improvement made all should be regarded as belonging to the utility model discloses a protection scope.
