Description
技术领域
本发明涉及PVC管技术领域,尤其涉及一种钢带增强PVC管。
背景技术
PVC管的主要成份为聚氯乙烯,加入适量的稳定剂、润滑剂、填充剂、增色剂等经塑料挤出机挤出成型和注塑机注塑成型,通过冷却、固化、定型、检验、包装等工序以完成管材、管件的生产。PVC管的最上层是漆,中间的主要成分是聚氯乙烯,最下层是背涂粘合剂,它是当今世界上深受喜爱、颇为流行并且也被广泛应用的一种合成材料。
PVC管材技术与设计原则:
1、树脂应选择PVC-SC5树脂或PVC-SG4树脂,也就是聚合度在1200~1000的聚氯乙烯树脂。
2、加入热稳定体系。根据生产实际要求选择,注意热稳定剂之间的协同效应和对抗效应。
3、须加入冲击改性剂。可以选择CPE和ACR冲击改性剂。根据配方中其他组成以及挤出机塑化能力,加入量在8~12份。CPE价格较低,来源广泛,ACR耐老化能力、焊角强度高。
然而现有的钢带增强PVC管仍存在不足之处:首先,大多采用组合粘接式结构,制造起来费时费力,同时粘接的结构,易受到高温的作用而脱落,结构稳定性较差,其次,内部无设置滤液结构,无法有效的将进入到PVC管内部的液体进行过滤处理,液体中杂质进入到管道的内部,既易导致管道内壁的磨损,同时也易导致管道的堵塞。
发明内容
本发明的目的在于:为了解决制造起来费时费力,同时粘接的结构,易受到高温的作用而脱落,结构稳定性较差的问题,而提出的一种钢带增强PVC管。
为了实现上述目的,本发明采用了如下技术方案:
一种钢带增强PVC管,包括内层PVC管、外层PVC管和设置在内层PVC管和外层PVC管之间的钢带圈,其特征在于,所述内层PVC管外表壁顶部安装有第一螺套,所述内层PVC管的外表壁位于第一螺套的下方套接有钢带圈,所述内层PVC管的外表壁底部开设有第二外螺纹,所述内层PVC管的外侧设置有外层PVC管,所述外层PVC管的内表壁顶部开设有配合第一螺套使用的第一外螺纹,所述外层PVC管的内表壁底部安装有配合第二外螺纹使用的第二螺套;现有的钢带增强PVC管大多采用组合粘接式结构,制造起来费时费力,同时粘接的结构,易受到高温的作用而脱落,结构稳定性较差,使得该钢带增强PVC管适用场合受限,因此,本申请通过采用组合旋接式结构,便于钢带增强PVC管的组装固定处理,既降低了组装钢带增强PVC管的工作量,同时也提升了钢带增强PVC管整体结构的稳定性;使用时,需要进行组装处理时,将钢带圈滑接至内层PVC管的外表壁,再将外层PVC管滑入到内层PVC管的外部,再转动内层PVC管或将外层PVC管,外层PVC管内侧的第一外螺纹,便会旋入至内层PVC管的第一螺套上,同时外层PVC管内侧的第二螺套,便会旋入到内层PVC管的第二外螺纹上,便完成了外层PVC管的初步固定,从而实现钢带增强PVC管的安装,简单可行,同时,便于更换增强钢带PVC管中的损坏部件,使得增强钢带PVC管的适用场合大大增多。
优选的,所述内层PVC管的顶端开口处固定连接有过滤筒,且过滤筒的内侧嵌设有滤网,所述过滤筒的一侧连通有排渣管,且排渣管的开口端外侧通过螺纹旋合连接有密封旋帽,通过采用上述技术方案,现有的PVC管未设置有滤网,液体直接进入到PVC管内并流过PVC管,此时,会出现液体中杂质在进入到管道的内部时,刮伤管道内壁,导致管道内壁的磨损,同时也容易导致管道的堵塞,影响后续液体通过PVC管,通过滤网的设置,可将进入到过滤筒内的液体,通过滤网进行过滤处理,液体继续在PVC管内流过,而滤渣留在滤网的一侧,但是,此时,仍存在问题,随着滤渣越来越多,会使得滤网处堆积较多的滤渣,也会影响后续液体通过PVC管,因此,此时,需要设置排渣管,利用排渣管便于杂质的冲洗排出,减少滤网处滤渣的堆积,另外,设置密封旋帽,便于排渣管开口处的密封处理,从而提高了PVC管的使用寿命。
优选的,所述钢带圈的内部关于钢带圈的竖直中线呈环形阵列开设有多组漏孔;通过采用上述技术方案,多组漏孔的设置,便于钢带圈的散热处理,同时,多组漏孔的开设,降低了钢带圈的材料用量,从而降低了钢带增强PVC管的制造成本。
优选的,所述第一螺套和第二螺套的尺寸相同,且第一螺套和第二螺套截面厚度与钢带圈的截面厚度大小相等;通过采用上述技术方案,便于钢带圈限位固定在内层PVC管和外层PVC管之间的缝隙处,从而提升了钢带圈固定的稳定性,同时,能够实现内层PVC管、钢带圈和外层PVC管间紧密贴合,避免由于液体流速过快,导致内层PVC管、钢带圈和外层PVC管的分离,影响PVC管的组装效果,从而提高了PVC管的适应性。
优选的,所述外层PVC管的两个开口端外侧均通过螺纹旋合连接有贯穿外层PVC管的固定螺柱,所述内层PVC管的内部靠近固定螺柱的一侧开设有配合固定螺柱使用的固定螺孔;通过采用上述技术方案,固定螺柱和固定螺孔的设置,便于旋紧后内层PVC管和外层PVC管的进一步固定处理,从而进一步提升了内层PVC管和外层PVC管安装固定的稳定性。
优选的,每个所述漏孔处均匀设置有截面为三角形的倒戗刺;通过采用上述技术方案,截面为三角形的倒戗刺能够对未被滤网过滤的滤渣进行二次碎裂,进一步减少了滤渣的体积,进一步降低了滤渣对PVC管管道的损伤,从而提高了PVC管的使用寿命;同时,截面为三角形的倒戗刺在液体压力下向外层PVC管的一侧运动,使得截面为三角形的倒戗刺刺入到外层PVC管的管壁上,进一步提高了外层PVC管与钢带圈间的紧密度,而被截面为三角形的倒戗刺碎裂的滤渣填补到钢带圈与内层PVC管间的间隙中,避免钢带圈与内层PVC管间发生脱离,从而进一步保证了内层PVC管、钢带圈和外层PVC管间的紧密度,同时,能够提高PVC管的使用寿命。
综上所述,由于采用了上述技术方案,本发明的有益效果是:
1、本发明中,采用组合旋接式结构,在内层PVC管的外表壁顶部和底部分别设置有第一螺套和第二外螺纹,同时在外层PVC管的内表壁顶部和底部分别设置有第一外螺纹和第二螺套,需要组装时,可将钢带圈滑接至内层PVC管的外表壁,再将外层PVC管通过第一外螺纹和第二螺套,旋入至内层PVC管的第一螺套和第二外螺纹上,旋入后,便可将外层PVC管的固定螺柱,旋入到内层PVC管的固定螺孔内,便完成了钢带增强PVC管的组装固定处理,这种结构便于钢带增强PVC管的组装固定处理,既降低了组装钢带增强PVC管的工作量,同时也提升了钢带增强PVC管整体结构的稳定性。
2、本发明中,内部设置有滤液结构,在内层PVC管的顶端设置有过滤筒,且在过滤筒的内部设置有滤网,并且在过滤筒的一侧设置有排渣管和密封旋帽,滤网可将进入到PVC管内部的水进行过滤处理,同时过滤下的杂质,在重力和水流的共同作用下,便会集中在排渣管的附近,打开密封旋帽,便可将杂质冲洗出,这种结构可将进入到PVC管内部的溶液进行过滤处理,既降低了管道内部的磨损,同时也提升了液体流通的稳定性。

作为本发明的一种具体实施方式,所述外层PVC管9的两个开口端外侧均通过螺纹旋合连接有贯穿外层PVC管9的固定螺柱10,所述内层PVC管1的内部靠近固定螺柱10的一侧开设有配合固定螺柱10使用的固定螺孔11;通过采用上述技术方案,固定螺柱10和固定螺孔11的设置,便于旋紧后内层PVC管1和外层PVC管9的进一步固定处理,从而进一步提升了内层PVC管1和外层PVC管9安装固定的稳定性。
作为本发明的一种具体实施方式,每个所述漏孔7处均匀设置有截面为三角形的倒戗刺71;通过采用上述技术方案,截面为三角形的倒戗刺71能够对未被滤网14过滤的滤渣进行二次碎裂,进一步减少了滤渣的体积,进一步降低了滤渣对PVC管管道的损伤,从而提高了PVC管的使用寿命;同时,截面为三角形的倒戗刺71在液体压力下向外层PVC管9的一侧运动,使得截面为三角形的倒戗刺71刺入到外层PVC管的管壁上,进一步提高了外层PVC管9与钢带圈6间的紧密度,而被截面为三角形的倒戗刺71碎裂的滤渣填补到钢带圈6与内层PVC管1间的间隙中,避免钢带圈6与内层PVC管1间发生脱离,从而进一步保证了内层PVC管1、钢带圈6和外层PVC管9间的紧密度,同时,能够提高PVC管的使用寿命。
工作原理:使用时,需要进行组装处理时,将钢带圈6滑接至内层PVC管1的外表壁,再将外层PVC管9滑入到内层PVC管1的外部,再转动内层PVC管1或将外层PVC管9,外层PVC管9内侧的第一外螺纹12,便会旋入至内层PVC管1的第一螺套2上,同时外层PVC管9内侧的第二螺套13,便会旋入到内层PVC管1的第二外螺纹8上,便完成了外层PVC管9的初步固定,在将外层PVC管9上的固定螺柱10旋入到内层PVC管1的固定螺孔11内部,便完成了外层PVC管9进一步固定处理,当钢带增强PVC管传输液体时,过滤筒3内部的滤网14,可将液体进行过滤处理,过滤下的杂质,由于重力和液体流动的作用,便会集中制排渣管4的附近,需要排出杂质时,旋开排渣管4上的密封旋帽5,滤网14上的杂质便可在水流的作用下冲洗出。
以上所述,仅为本发明较佳的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本发明揭露的技术范围内,根据本发明的技术方案及其发明构思加以等同替换或改变,都应涵盖在本发明的保护范围之内。
