Working principle

采用双偏心密封结构，关闭时越关越紧，开启后确保密封面与密封圈脱离接触，保护密封圈不受损伤，延长使用寿命。密封面、密封圈选用不锈钢制作，其耐锈蚀、耐高温性保证了密封性能的可靠。采用半轴结构，蝶板为桁架式结构，其强度高、过流面积大、流阻小、节省能源。本阀具有介质双向截止密封功能，其渗漏量为零。

手动高性能密闭蝶阀；通过转动手轮，经蜗轮副减速，带动阀轴、蝶板作90°范围内的旋转，达到截断、连通或调节流量的目的。阀门的开启或关闭位置均由限位机构限位，并有指示机构显示蝶板位置状态。

自动高性能密闭蝶阀；由电动执行器接受变送、调节DCS、PLC等上位仪表的控制信号或操作器手控信号，输出角位移带动传动轴，把动力传给阀轴带动蝶板作同步旋转运动，达到全开、全闭及任意调节的目的。电动执行器与蝶板的开度同步反馈0～10mA或 4～20mA直流电信号，用户可根据电流信号来控制蝶板的任意开度，达到调节的目的。

The valve adopts double eccentric sealed structure. The more it is close, the more it is tight. The sealing surface will separate from sealing ring, which prevent the sealing ring from damaging. The material of sealing surface and ring is stainless steel whose resistance of abrasion and high temperature ensure the reliability of sealing performance. It adopts half shaft structure and the butterfly disc is trussed structure, having the features of great strength, big flow area, little lost of flow resistance and saving energy. The valve has the function of stopping and sealing medium in double directions and without leakage.

Manual high performance sealed butterfly valve: rotate hａnd wheel to drive the valve axle and butterfly disc rotate in the range of 90°to cut off, connect or adjust the flow. The open or close position of the valve gate is limited by the limit device. The indicating device displays the position of butterfly disc.

Automatic high performance sealed butterfly valve: control signal or manual signal of DCS or PLC meter is accepted, adjusted and transmitted by electric actuator. Then the actuator outputs the angle moving to drive the transmission shaft. It drives the axle and disc rotating synchronously in order to adjust freely, full open and close. The open angle between actuator and disc’s sync feedback DC signal is 0～10mA or 4～20mA. User can control the random open angle of disc according as the current signal.

安装及调试：

Installation and regulation

l  安装前必须清洁阀体内腔，不允许有任何杂物和污垢附着（特别注意密封面、密封圈的清洁）。

l  安装前检查阀门各部位是否有松动现象，对阀门进行开启、关闭一个周期是否有异常现象，同时检查阀门的启闭位置是否准确。

l  水平安装或垂直安装的阀门阀轴应处于水平位置，传动装置不允许作起吊用，并严禁损伤。

l  本阀具有一定的双向密封性能，若只需控制单方向流动的介质时，其安装方向应参照阀体上箭头所示，该箭头所指为介质流向。

l  安装如示意图，加密封垫后均匀锁紧联接螺栓。

l  调整完成后必须进行综合性能检查：接通电源开启阀门，当阀门至“全开”“全闭”位置时，行程控制机构应准确地切断电源，而转矩限位机构处于临界动作状态。开度指示机构应准确地显示阀门的开启状态。

l  电动切换手动操作时，应切断电源，不得在手轮上再增加辅助杠杆，手轮顺时针旋转为关，反之为开，阀板开启角度为0°~90°。

l   The body must be cleaned before installed and there is no dirt and sundries clinging to the body, especially the sealing surface and ring.

l   Check the valve gate before install. Open and close the valve by hａnd for a period and check the open-close position of the valve gate.

l   The valve axle must be on the horizontal position when installed in horizontal or vertical. The transmission device cannot be hoisted and avoid damage when installed.

l   The valve has the feature of double-sealing performance. The installation direction should refer to the arrow on the valve body, which indicates the medium flow direction, when control the flow of medium in single direction. 

l   Installation of flange connecting valve is on diagram. Lock down the connecting bolt after add sealing washer.

l   Synthetic performance of the valve must be done after adjust is over: turn on the power and open the valve, the stroke control device should cut down the power exactly when the valve is in the state of full open or full close. While the torque limit device is in critical state. The open angle indicating device should display the open state of the valve gate exactly.

l   The power must be shut down when operating by manual. Assistant pole can’t be added to hａnd wheel. Clockwise rotation of hａnd wheel means open and anticlockwise means close. Open angle is 0~90°.

运输及保管：

Transportation and protection

l  运输时应避免撞击蝶阀及传动装置，阀门应处于全闭位置，以防在运输中密封面和传动部件损坏。

l  当阀门水平放置运输时，传动装置及传动部位应悬空，以防止传动轴受力过大而变形损坏。

l  该阀应存放在干燥的室内，不允许露天存放或堆置。长期存放时应使阀门处于关闭状态，各传动部位加润滑油，传动装置作防潮、防尘处理。

l   Avoid bumping of valve and transmission device. The valve is in full close in order to avoid damage of sealing surface and driving part.

l   Transmission device and part should be hung up when the valve is in horizontal in order to prevent damage of driving axle.

l   The valve should be stored in dry room. It should be in full close state when long stored. Add lubrication to the transmission part and the device should be dampproof and dustproof.

l  对阀门周期性维护时应全面检查阀的各密封部位、传动部位，对各密封部位应进行检测，对检测数据应记录在案。

l   Check the working condition of electric parts, control switch and sealing of pneumatic device regularly.

l   Add lubricant to the transmission parts regularly.

l   Check the sealing filler of the valve regularly. Complement or change filler avoiding leakage of medium.

l   Check the sealing parts and transmission parts thoroughly. Detect the sealing parts and the detecting data should be registered.
