DC6011   平行单闸板闸阀

    DC6011 series parallel single gate valve (also known as flat gate valve) is one of the important varieties of control valves in the production process. The flat gate valve has good opening and closing characteristics. It has the characteristics of full diameter, small flow resistance, good sealing and convenient switching. Applicable to pipelines and storage equipment for refined oil: petroleum, natural gas, and imported equipment for mining and media pipelines with suspended particles and fibers

    DC6011系列平行单闸板闸阀（又称平板闸阀）是生产过程中控制阀门的重要品种之一。平板闸阀具有良好启闭特性。具有全通径、流阻小、密封性好、开关方便等特点。可适用于成品油的输送管线和贮存设备：石油，天然气和开采进口装置以及带有悬浮颗粒、纤维的介质管道。

平行单闸板闸阀结构原理与特点

带导流孔闸板结构特点

1、闸板带一与阀体通道相同口径的通孔，阀门全开时，闸板导流孔与阀体通道形成直管段，可直接用毛球进行吹扫。
2、闸板开启或关闭行程中阀座始终与闸板接触吻合，软阀座在闸板运行过程中能够自动刮除闸板上的杂质，因此平板闸阀也适用于带悬浮颗粒、纤维介质；且阀座密封面不会受到阀体热变形的损坏。
3、两阀座为浮动式，具有软硬复合密封的特点，使用寿命长。当阀门内腔压力异常升高时，浮动阀座可自动将高压泄放排入管道。
4、阀体外部两阀座处设有注脂阀，当阀门使用过程中由于密封副磨损发生泄漏时，可通过此处注入密封脂，防止阀门泄漏。
5、阀体下部设有排污阀，可排放阀门内部积存的污物。

Structural Features of Shutters with Diversion Holes

1. The gate plate has a through hole with the same diameter as the valve body channel. When the valve is fully opened, the gate guide hole and the valve body channel form a straight pipe section, which can be directly blown with wool balls.

2. The valve seat is always in contact with the gate during the opening or closing stroke of the gate. The soft valve seat can automatically scrape off the impurities on the gate during the operation of the gate. Therefore, the flat gate valve is also suitable for suspension particles and fiber media And the sealing surface of the valve seat will not be damaged by the thermal deformation of the valve body.

3. The two valve seats are floating, with the characteristics of soft and hard compound seal, and long service life. When the pressure inside the valve cavity rises abnormally, the floating valve seat can automatically discharge high pressure into the pipeline.

4. There are grease injection valves at the two valve seats outside the valve body. When the valve leaks due to wear of the sealing pair during use, the sealing grease can be injected here to prevent the valve from leaking.

5. There is a drain valve in the lower part of the valve body, which can discharge the dirt accumulated in the valve.

无导流孔闸板结构特点

闸阀不带导流孔，阀门结构紧凑、体积小、重量轻。
闸阀可设计制造成V型、半圆形、五角形通道，使阀门具有调节性能，可任意开度调节，以满足管道系统对流量的要求。
两阀座为浮动式，具有软硬复合密封的特点，使用寿命长。当阀门内腔压力异常升高时，浮动阀座可自动将高压泄放排入管道。

Structural features of non-diversion gate

1. The gate valve does not have a diversion hole, and the valve has a compact structure, small size and light weight.

2. The gate valve can be designed and manufactured as a V-shaped, semi-circular, pentagonal channel, so that the valve has adjustable performance and can be adjusted at any opening to meet the flow requirements of the pipeline system.

3. The two valve seats are floating, with the characteristics of soft and hard compound seal, and long service life. When the pressure inside the valve cavity rises abnormally, the floating valve seat can automatically discharge high pressure into the pipeline.

4. There are grease injection valves at the two valve seats outside the valve body. When the valve leaks due to wear of the sealing pair during use, the sealing grease can be injected here to prevent the valve from leaking.

5. There is a drain valve in the lower part of the valve body, which can discharge the dirt accumulated in the valve.
