DC6011   平行單閘板閘閥

    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系列平行單閘板閘閥（又稱平板閘閥）是生產過程中控制閥門的重要品種之一。平板閘閥具有良好啟閉特性。具有全通徑、流阻小、密封性好、開關方便等特點?？蛇m用于成品油的輸送管線和貯存設備：石油，天然氣和開采進口裝置以及帶有懸浮顆粒、纖維的介質管道。

平行單閘板閘閥結構原理與特點

帶導流孔閘板結構特點

1、閘板帶一與閥體通道相同口徑的通孔，閥門全開時，閘板導流孔與閥體通道形成直管段，可直接用毛球進行吹掃。
2、閘板開啟或關閉行程中閥座始終與閘板接觸吻合，軟閥座在閘板運行過程中能夠自動刮除閘板上的雜質，因此平板閘閥也適用于帶懸浮顆粒、纖維介質；且閥座密封面不會受到閥體熱變形的損壞。
3、兩閥座為浮動式，具有軟硬復合密封的特點，使用壽命長。當閥門內腔壓力異常升高時，浮動閥座可自動將高壓泄放排入管道。
4、閥體外部兩閥座處設有注脂閥，當閥門使用過程中由于密封副磨損發生泄漏時，可通過此處注入密封脂，防止閥門泄漏。
5、閥體下部設有排污閥，可排放閥門內部積存的污物。

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.

無導流孔閘板結構特點

閘閥不帶導流孔，閥門結構緊湊、體積小、重量輕。
閘閥可設計制造成V型、半圓形、五角形通道，使閥門具有調節性能，可任意開度調節，以滿足管道系統對流量的要求。
兩閥座為浮動式，具有軟硬復合密封的特點，使用壽命長。當閥門內腔壓力異常升高時，浮動閥座可自動將高壓泄放排入管道。
閥體外部兩閥座處設有注脂閥，當閥門使用過程中由于密封副磨損發生泄漏時，可通過此處注入密封脂，防止閥門泄漏。
閥體下部設有排污閥，可排放閥門內部積存的污物。

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.
