Description

一种螺纹短节管
技术领域
本发明涉及工业管道技术领域,尤其涉及一种螺纹短节管。
背景技术
工业管道是工矿企业,事业单位为生产制作各种产品过程所需工艺管道、公用工程管道及其他辅助管道。工业管道广泛应用于各工矿企业、事业单位等各行各业中,分布于城、乡各个地域。工业管道是压力管道中工艺流程种类最多、生产制作环境状态变化最为复杂、输送的介质品种较多与条件均较苛刻的压力管道。
短节是工业管道连接中常用的一种配件。常见的有螺纹短节,分为双头外丝、单头外丝、平头外丝几种,另外还有以法兰连接的短节等。
现有技术中的螺纹短节管在连接的过程中普遍存在安装困难的情况,由于为了保证气密性和安全性,螺纹短节管往往强度很大。由于在制作的过程中,精度的误差难免会出现差错,有时口径只是大了几毫米,就导致螺纹短节管无法正常安装上去,需要拿去返工,而且即使尺寸合适在安装的过程中也会尤为费力。
发明内容
本发明要解决的问题是提供一种螺纹短节管。
本发明的技术方案如下:一种螺纹短节管,包括管体,所述管体两端设有贯通贯通管体的管口;其特征在于所述管口上设有倒角;所述管体两端的管口为锥形管;所述管体的壁厚不大于3毫米;所述管体内径的最小处不小于6毫米。
进一步,所述倒角斜面与管口的角度不大于40度。
进一步,所述所述任意管口的锥形部分长度不大于管体管长的四分之一。
进一步,所述管体内侧或者外侧设有螺纹。
本发明的有益效果在于:通过本发明螺纹短节管,在螺纹短节管的两端设置倒角,方便安装;同时将螺纹短节管的两端做成锥形管,在即使存在部分口径差异的情况下仍然得以安装。
附图说明
图1为本发明的半剖图。
其中:A、倒角,        B、壁厚,
      D、内径,        L、管长,
      L1、锥形部分长度,          1、管体,
      2、管口。
具体实施方式
下面结合附图对本发明的具体实施方式做出简要说明。
一种螺纹短节管,包括管体1,所述管体1两端设有贯通贯通管体的管口2。所述管口2上设有倒角A,所述倒角A斜面与管口2的角度不大于40度。所述管体1两端的管口2为锥形管,所述所述任意管口2的锥形部分长度L1不大于管体管长L的四分之一。所述管体1的壁厚B不大于3毫米;所述管体1内径D的最小处不小于6毫米。所述管体内侧或者外侧设有螺纹。
所述管体的材料根据情况选取不同的材料,但当采用碳钢为材料的时候,要将表面经过煮黑处理。
部分尺寸对照表:
以上对本发明的一个实施例进行了详细说明,但所述内容仅为本发明的较佳实施例,不能被认为用于限定本发明的实施范围。凡依本发明申请范围所作的均等变化与改进等,均应仍归属于本发明的专利涵盖范围之内。
