  金沙国际官网用橡胶接头主要由三部分组成,內胶层是由力威自主合成的橡胶来制 作的橡胶球体,增强层是采用帘子布来作为橡胶接头的添加物以增强橡胶接头的弹性 及耐磨性能,连接部分可以是法兰连接方式和套管连接方式,还有卡箍等多种连接方式可供选择。有人咨询问:橡胶软接头使用注意事项是什么?今天来介绍一下金沙国际官网橡胶软接头使用注意事项。

  Rubber joints for ventilation pipes are mainly composed of three parts. The inner rubber layer is a rubber ball made of rubber synthesized by Liwei. The reinforcing layer uses cord cloth as the additive of rubber joints to enhance the elasticity and wear resistance of rubber joints. The connecting part can be made of flange connection and sleeve connection, and there are many kinds of connection methods such as clamps. Someone asked: what are the precautions for the use of rubber soft joints? Today, I'd like to introduce the precautions for rubber flexible joint of Jinan ventilation pipe.

  金沙国际官网橡胶软接头安装时需要注意的事项有:

  Matters needing attention during installation of rubber soft joint of ventilation pipe include:

  1、橡胶接头在初次承受压力如安装试压等后或长期停用再次启用前,应将螺栓重新加压拧紧再投入运行橡胶伸缩器。

  1、 After the rubber joint bears the pressure for the first time, such as installation and pressure test, or before it is put into use again after being stopped for a long time, the bolt shall be re pressurized and tightened before being put into operation.

  2、当管道介质为酸,碱,油,高温及其他特殊材料时应选用高于管道工作压力一个挡位的橡胶接头。

  2. When the pipeline medium is acid, alkali, oil, high temperature and other special materials, the rubber joint with a gear higher than the working pressure of the pipeline shall be selected.

  3、连接橡胶接头的接口应是阀门法兰或符合GB/T9115.1(RF)的法兰。

  3. The interface connecting rubber joint shall be valve flange or flange conforming to GB / t9115.1 (RF).

  4、当管道产生瞬间压力且大于工作压力时应选用高于工作压力一个挡位的接头。

  4. When the instantaneous pressure of the pipeline is greater than the working pressure, the joint with a gear higher than the working pressure shall be selected.

  5、橡胶接头正常使用介质温度是0-60℃的普通水,特殊介质如:油、酸、碱、高温及其他腐蚀性和质地坚硬的情况下,应选用相对应的橡胶接头材质,不可盲目串用或通用。

  5. The normal use medium temperature of rubber joint is 0-60 ℃ ordinary water. In case of special medium such as oil, acid, alkali, high temperature and other corrosive and hard conditions, the corresponding rubber joint material shall be selected, and it is not allowed to be used in series or in general.

  6、高层给水或悬空给水,管道应固定在吊架,托架或锚架上,且不能让接头承受管道自身重量和轴向力,否则橡胶接头应配备防拉脱装置,并且其承受力大于管道轴向力。

  6. For high-rise water supply or suspended water supply, the pipe shall be fixed on the hanger, bracket or anchor frame, and the joint shall not bear the weight and axial force of the pipe itself, otherwise the rubber joint shall be equipped with anti pulling device, and its bearing force shall be greater than the axial force of the pipe.

  7、可曲挠橡胶接头使用在水泵进出口时,应位于近水泵一侧,与水泵之间应安装金属变径接头,且安装在变径的大口径处。

  7. When the flexible rubber joint is used at the inlet and outlet of the water pump, it shall be located at the side near the water pump, and a metal reducer joint shall be installed between the flexible rubber joint and the water pump, and it shall be installed at the large diameter of the reducer.

  8、当管道位移量≥接头的补偿量时,应增加接头的数量来平行位移量,严禁为了调整管道的超差,使接头处于限的挠曲位移和偏差状态,更不能超限度伸缩,位移,偏转等。

  8. When the displacement of the pipeline is equal to or greater than the compensation of the joint, the number of joints shall be increased to parallel the displacement. It is strictly prohibited to adjust the over tolerance of the pipeline, so that the joint is in the state of limited deflection displacement and deviation, not to mention the over tolerance expansion, displacement, deflection, etc.

  9、安装橡胶接头时,螺栓的螺杆应伸向接头外侧,每一法兰端面的螺栓按对角加压的方法反复均匀拧紧,防止压偏。丝扣接头应使用标准扳手匀力拧紧,不要用加力杆加力使活接头滑丝,滑棱,断裂,而且要定期定时检查,以免松动造成脱盘或渗水。

  9. When installing the rubber joint, the screw of the bolt shall extend to the outside of the joint, and the bolt of each flange end face shall be tightened repeatedly and evenly according to the method of diagonal pressure to prevent the pressure deviation. Screw thread joint shall be tightened evenly with standard spanner. Do not force the flexible joint with force bar to make the sliding thread, sliding edge and fracture. Besides, regular and regular inspection shall be carried out to avoid disc breaking or water seepage caused by loosening.

  10、使用或储存橡胶接头,应避免高温,臭氧,油及酸碱环境,用在室外或向阳迎风的管道应搭建遮阳架,严禁曝晒,雨淋,风蚀。橡胶接头表面严禁刷涂油漆和缠绕保温材料,因橡胶接头产品存在老化问题,应及时检查更换。

  10. When using or storing rubber joints, avoid high temperature, ozone, oil and acid-base environment. For outdoor or windward pipes, sunshade shall be set up. Exposure, rain and wind erosion are strictly prohibited. It is strictly prohibited to brush paint and wind insulation materials on the surface of rubber joint. Due to aging problems of rubber joint products, check and replace them in time.
