结构特点：
1、阀座采用O形密封圈密封和施加预紧力的浮动阀座结构，使平板闸阀进出口双向密封；并且该结构的启闭力矩仅为普通阀门的1/2，能达到轻松开、关阀门
2、在全开时，通道平滑为直线，流阻系数极小，无压力损失，可通毛球清扫管线
3、采用带自密封能力的填料结构，无需经常调节，开、关极为轻便，且密封性可靠，填料函处设有辅助密封油脂注入结构，密封性能可靠，真正达到零泄漏；解决了通用阀门填料处最容易外漏的弊病
4、平板闸阀关闭时能自动卸掉内腔高压，***使用安全
5、全封闭结构，防护性能好，可适应全天候要求

1.阀座的密封结构应为弹性有预紧力，上、下游密封座同时密封的结构。阀座与密封物间始终为面对面密封。
2.阀座有自清洗功能，并且在阀门开启或关闭过程中不受气流的直接冲刷。阀座应由有润滑、不磨损材料制成。
3.阀门执行机构的故障不会影响到阀门的其它部分，维修和更换工作能够在不拆下阀门的情况下进行。
(1) 轭架套管 – 铝青铜轭架套管配置针形止推轴承，程度减少操作扭矩。
(2) 阀杆 – 螺纹长度直到托架；销钉和点焊；具有稳定性。
(3) 压力密封 – 结构简单，配置分段扣环和镀银低碳钢垫圈，有助于拆卸和实现的阀帽密封。
(4) 阀座环 – 焊接阀座环垂直于流动通道，易于维护。
(5) 执行机构 – 这些阀门可以配置电动、液动或气动执行机构。DN300以下配置标准手动手轮，DN350以上配置斜齿轮操作机构。
(6) 轭架 – 完全装配式轭架通过抗震测试，易于维护和安装执行机构。
(7) 压盖 – 两件式，自调节压盖，避免被弹出。
(8) 整体后座 – 硬面，使用寿命最长。

Structure features:

1, seat O ring seals and pre-tightening force of the floating seat structure, make the seal of flat gate valve import and export; And the structure of the open-close torque is only 1/2 of ordinary valves, can achieve easily open and close the valve

2, when fully open, smooth channel for the straight line, small flow resistance coefficient, no pressure loss, can connect the bulb cleaning line

3, USES the packing structure with the sealing ability, without constant adjustment, features very light open and close, and the sealing is reliable, an auxiliary sealing grease injection structure is set in the packing, the sealing performance absolutely reliable and truly achieve zero leakage; To solve the packing place of universal valves to be easiest leak outward ills

4, flat gate valve is closed automatically removing the inner cavity and pressure, ensure use safety

5, fully closed structure, protective performance is good, can adapt to all requirements

1. The seat of the sealing structure should be elastic pre-tightening force, either upstream or downstream seal seat sealing structure at the same time. Seating and sealing seal between content is always face to face.

2. The seat has self-cleaning function, and in the process of the valve opened or closed without being directly eroded by the airflow. The seat should consist of lubrication, no wear materials.

3. The valve actuator fault will not affect other parts of the valve, repair and replacement work can be conducted without dismantling the valve.

(1) the yoke sleeve - aluminum-bronze yoke sleeve needle thrust bearing, the greatest degree to reduce operating torque.

(2) stem - length of thread until the carrier; Pin and spot welding; Has the stability.

(3) pressure seal - uncomplicated design, configuration of segmented retaining ring and mild steel silver plated gasket to aid disassembly and provide maximum bonnet seal.

(4) the seat ring - welded-in seat rings are perpendicular to the flow channel, easy to maintain.

(5) actuators - these valves can be furnished with electric, pneumatic or hydraulic cylinder actuators. 12 the following configuration standards manual handwheel, oblique gear operator DN350 above configuration.

(6) yoke - fully fabricated yoke is seismically testing, easy maintenance and actuator mounting.

(7) gland - two piece, self-adjusting gland, avoid being pop up.

Integral backseat - hardfaced (8), the longest service life.
