结构特点

Structure characteristic

•  采用高科技手段加工“密封副”,使密封面的硬度高达 HRC57-60 ,具有耐高温、耐腐蚀、 耐磨损等特性。与同等金属硬密封蝶阀、球阀相比,其使用寿命成倍增长。

•  采用半球直通式,开启后体内介质畅通无阻、流通阻力损失小、过流量大,具有节能和操作轻便省力等优点。

•  开启力矩小,楔紧力大。磨损后,能自行补偿,密封性好,性能稳定。

•  不受安装工况的限制,不受介质流动方向的限制。可任意角度安装,同时双向密封。

•  适用于水、气、热能、浆液、晶粒、粉状物料等介质,特别是能满足两相流溶液工艺流程中易沉淀、结垢、结晶、析出、杂物、异物混杂的介质、污水及腐蚀性、高冲刷性、琢磨性强的特殊需求。适用性广,可满足不同工况、不同介质的需求。

•  驱动形式多样,设有手动、蜗轮传动、电动、电液动、气动、自动调节等,充分满足不同工艺的需求。配套高科技智能控制系统,实现整个工程的自动化及联网控制。

•  The seal is processed in the high tech, which makes the hardness of seal face up to HRC57-60. It is endurable in high temperature, resistant in abrasion and antifriction. It has longer life than that of butterfly valve and ball valve with the same metal hardness.

•  It adopts hemisphere straight structure. The medium can flow without resistance after open the valve. The valve has the features of little in the lost of flow resistance, great in flow, saving energy and handy operation etc.

•  The open torque is little and the valve can self compensate after wearing because of big chocking force. The seal performance is good and stable.

•  It can be installed at any angle and sealed at two-way at the same time, which cannot be affected by the working condition and flow direction of medium.

•  It is suitable for medium such as water, gas, heat energy, crystal and powder material etc, especially suitable for medium of easy sedimentation, fouling, crystal, lumber, mixed with foreign impurity, sewage and medium with corrodibility, high scouring and great friction. The using of valve is wide and it can meet different condition and different medium demands.

•  The driving type is manual, worm gear, electric, electric hydraulic, pneumatic, automatic adjusting etc, which satisfies different process requirement. The whole engineering automation and network control can be realized when the valve is equipment with high tech intelligent control system.

使用说明:

 Working explanation

•  安装前必需清洁阀门内腔 , 不允许有任何杂物和污垢附着。

•  安装前先试运行及进行压力试验,无异常现象可上线安装。传动装置不允许作起吊用并严禁损坏。

•  安装时请认清介质流向并按阀体上指示箭头方位正确安装。安装时两法兰间需加密封垫片,然后均匀拧紧螺栓。

•  安装完毕后,试运行阀门,无异常现象方可投入使用。

•  The body must be cleaned before installed and there is no dirt and sundries clinging to the body.

•  Trial operation and pressure text is necessary for the valve. Install the valve after there is no abnormal condition. The driving device cannot be hoisted and avoid damage when installed.

•  Pay attention to the flow direction of medium and install the valve referring to the indicating arrow on the valve body. Add sealed shim between the two flanges and then lock down the bolt.

•  Debug the valve when the installation is over. The valve can be put into using if there is no abnormal condition.
