Abstract
Aircraft environmental control system compensation rubber corrugated flexible pipe, belongs to aircraft environmental control system assembly type rubber hose.It is assembled by the corrugated body in tube wall vertical section and the outer becket of pipe, and its middle tube body is followed successively by inner glue layer, fabric reinforcement layer, mesoglea, outer fabric heavy seal coat and formed from inside to outside；Inner glue layer, the main body sizing material of mesoglea are silicon rubber；Fabric reinforcement layer and outer fabric heavy seal coat use the terylene buffering fabric crossed through coupling agent pretreatment.Its high-low temperature resistant（‑60~+250℃）, ageing-resistant performance it is stable, there is good elasticity, air-tightness, flex fatig resistance, fabric and rubber layer bonding strength to significantly improve, storage life 5 years, service life 10 years, meet the design requirement of new unmanned plane complete machine.It can prevent excessively expansion occur during flexible pipe use using assembled metal ring outside body.Pipe structure is simple, and compensating action is obvious, is easily installed and promotes.
Description
Technical field
The utility model belongs to aircraft environmental control system assembly type rubber hose.
Background technology
Unmanned plane environmental control system known to China is provided with one section of compensation rubber between switching regulator inlet valve and conduit at present
Glue bellows.Its working media is pressure air, and its main technique requirements is air pressure change to be resistant to, high-low temperature resistant impact, footpath
It is intended to that there is certain compensation function to axial direction；Its storage life is 3 years, and service life is 5 years；Body main body sizing material is
Natural rubber is used in combination with butadiene rubber；Enhancement layer uses individual layer knitted polyester cloth.As China's Aviation Industry and strategic development need
Will, unmanned air vehicle technique is also evolving.New unmanned plane it is also proposed higher to compensation rubber hose used in environmental control system
It is required that：Between temperature in use is -60 ~+250 DEG C, storage life is 5 years, service life is 10 years.Obviously it is existing compensation
Rubber corrugated flexible pipe can not meet to require, to meet the global design requirement of new unmanned plane, redesign a kind of aircraft ring
Control system is imperative with compensation rubber hose.
The content of the invention
The purpose of this utility model is a kind of new unmanned plane environmental control system compensation rubber corrugated flexible pipe of research, to solve
Meeting storage life 5 years, on the premise of service life 10 years, be provided simultaneously with excellent elasticity, air-tightness, flex fatig resistance,
The excellent properties such as high-low temperature resistant.
It is soft that technical solution adopted in the utility model is to provide a kind of type aircraft environmental control system compensation rubber corrugated
Pipe, it is assembled by the corrugated body in tube wall vertical section and the outer becket of pipe.In its middle tube body is followed successively by from inside to outside
Glue-line, fabric reinforcement layer, mesoglea, outer fabric heavy seal coat are formed；The inner glue layer, the main body sizing material of mesoglea are silicon rubber
Glue；The fabric reinforcement layer and outer fabric heavy seal coat use the terylene buffering fabric crossed through coupling agent pretreatment.
Compared with known technology, the utility model uses silicon rubber to be pre-processed for main body sizing material, enhancement layer using coupling agent
Terylene buffering cloth, its high-low temperature resistant（-60~+250℃）, ageing-resistant performance it is stable, there is good elasticity, air-tightness, resistance to bend
Scratch fatigue, fabric and rubber layer bonding strength significantly improve, storage life 5 years, service life 10 years, meet it is new nobody
The design requirement of machine complete machine.It can prevent excessively expansion occur during flexible pipe use using assembled metal ring outside body.Body
Simple in construction, compensating action is obvious, is easily installed and promotes.
Brief description of the drawings
Fig. 1 is vertical profile structural representation of the present utility model.
The outer fabric heavy seal coat 5- beckets of 1- inner glue layers 2- fabric reinforcement layer 3- mesoglea 4- in figure.
Embodiment
Structure and manufacture method step of the present utility model are described in detail below in conjunction with accompanying drawing：
As illustrated, the utility model is from inside to outside successively by inner glue layer（1）, fabric reinforcement layer（2）, mesoglea（3）, it is outer
Fabric heavy seal coat（4）Form.
Making step is as follows：Elastomeric compound cooperation-silica gel elastomeric compound preparation-back mixing slice-film pastes with buffering fabric calendering
Synthesize compound raw stock-be molded on mould tire（Two layers）- plus outer mold integrally vulcanizes-drives mould cooling-Burr removal-installation stainless steel
Becket（5）.
The connected mode of two ends is connected using stainless steel hose clamp.
