Abstract
一种耐高压柔性软管，在结构上由：铁氟龙管(1)、不锈钢编织网(2)、防潮纱管(3)、不锈钢波纹管(4)构成，其特征在于：设置在最外层的是具有均匀弯折性能的不锈钢波纹管(4)，并且在不锈钢编织网(2)和不锈钢波纹管(4)之间设置的是具有吸湿防潮及耐腐蚀作用的防潮纱管(3)，当弯曲耐高压软管时，具有均匀弯折性能的不锈钢波纹管(4)可以均匀地弯曲内层的铁氟龙管(1)，使弯折处形成一个与两边管体都相切的圆弧，进而均匀化了变形量，改善了耐高压软管由于弯折而产生的不均匀变形，为防止耐高压软管受力不均匀而破裂创造了条件。
A high-pressure-resistant flexible hose is structurally composed of a Teflon tube (1), a stainless steel braided net (2), a moisture-proof yarn tube (3), and a stainless steel corrugated tube (4). The outer layer is a stainless steel corrugated tube (4) with uniform bending performance, and a moisture-proof yarn tube (3 ), when bending the high-pressure hose, the stainless steel bellows (4) with uniform bending properties can evenly bend the inner Teflon tube (1), so that the bend forms a tangent to both sides of the pipe body The circular arc evens out the amount of deformation, improves the uneven deformation of the high-pressure hose due to bending, and creates conditions for preventing the high-pressure hose from being broken due to uneven force.
Description
技术领域： Technical field:
本发明涉及耐高压柔性软管结构技术。The invention relates to a high-pressure-resistant flexible hose structure technology.
背景技术： Background technique:
目前，传统耐高压软管是内层的聚四氟乙烯管(即铁氟龙管)在外层加固一层不锈钢丝的方法制作而成的，其不足点是：抗折弯性能不足，尤其是在高压状态下输送气、液体时，当弯曲耐高压软管时，由于耐高压软管管壁受压不均匀，导致管身折弯处各点变形不一致，进而造成耐高压软管破裂泄漏，耽误生产，造成生产安全问题。At present, the traditional high-pressure hose is made of a polytetrafluoroethylene tube (ie Teflon tube) in the inner layer and a layer of stainless steel wire on the outer layer. The disadvantages are: insufficient bending resistance, especially When transporting gas and liquid under high pressure, when the high pressure resistant hose is bent, due to the uneven pressure on the wall of the high pressure resistant hose, the deformation of the bending points of the pipe body is inconsistent, which in turn causes the high pressure resistant hose to rupture and leak. Delay production, resulting in production safety problems.
发明内容： Invention content:
本发明之目的是提出一种改善现有状况的耐高压软管。The object of the present invention is to propose a high pressure resistant hose which improves the existing situation.
本发明的关键在于：在结构上，有从内层到外层依次为铁氟龙管、不锈钢编织网、防潮纱管和不锈钢波纹管，The key of the present invention is: in terms of structure, there are Teflon tubes, stainless steel braided nets, moisture-proof yarn tubes and stainless steel corrugated tubes in sequence from the inner layer to the outer layer,
其特征在于：设置在最外层的是具有均匀弯折性能的不锈钢波纹管。It is characterized in that: the outermost layer is a stainless steel bellows with uniform bending performance.
本发明与现有技术比较的特点：由于设置在最外层的是具有均匀弯折性能的不锈钢波纹管，当弯曲耐高压软管时，具有均匀弯折性能的不锈钢波纹管可以均匀地弯曲内层的铁氟龙管，使弯折处形成一个与两端管体都相切的圆弧，进而均匀化了变形量，改善了耐高压软管由于弯折而产生的不均匀变形，为防止耐高压软管受力不均匀而破裂创造了条件。The characteristics of the present invention compared with the prior art: Since the outermost layer is a stainless steel bellows with uniform bending performance, when bending a high-pressure hose, the stainless steel bellows with uniform bending performance can evenly bend the inner The layered Teflon tube makes the bend form a circular arc tangent to both ends of the tube body, thereby uniformizing the deformation and improving the uneven deformation of the high-pressure resistant hose due to bending. The high-pressure hose is unevenly stressed and ruptured to create conditions.

具体实施方式： Detailed ways:
本发明在结构上由：铁氟龙管1、不锈钢编织网2、防潮纱管3、不锈钢波纹管4构成，Structurally, the present invention is composed of: Teflon
其特征在于：设置在最外层的是具有均匀弯折性能的不锈钢波纹管4，并且在不锈钢编织网2和不锈钢波纹管4之间设置的是具有吸湿防潮及耐腐蚀作用的防潮纱管3。It is characterized in that: the stainless steel
使用本发明输送高压气、液体时，若产生了弯折，由于在本发明的最外层是设置了具有均匀弯折性能的不锈钢波纹管4的，所以使得原本不具备均匀弯折性能的铁氟龙管1可以在弯折处形成一个与两端管体都相切的圆弧，即均匀弯折了铁氟龙管1，均匀分布了铁氟龙管1内壁的气、液体压力，为防止整个管体因受力不均匀而破裂创造了条件，由于设置在不锈钢波纹管4和不锈钢编织网2之间的防潮纱管3是呈软性的，可以使得不锈钢波纹管4与不锈钢编织网2充分接触，将内部管体的应力更好地分散到不锈钢波纹管4上，为进一步防止管体因受力不均匀而破裂创造了条件，并且防潮纱管3还可以阻止外界的水汽或液体进入管体内部，为防止外界液体渗入并接触而腐蚀内部管体创造了条件。When using the present invention to transport high-pressure gas and liquid, if there is bending, because the outermost layer of the present invention is provided with a
