放料閥主要用于反應器，儲罐和其他容器的底部排料，借助于閥門底部法蘭焊接于儲罐和其他容器的底部，因此消除工藝介質常在容器底部的殘留現象。放料閥根據實際情況的需要，放底結果設計為平底，閥體為V型，并提供提升和下降兩種工作方式的閥瓣。閥體內腔裝有耐沖刷、耐腐蝕的密封圈，在開啟閥門瞬間，可以保護閥體不被介質沖刷、腐蝕，并對密封圈進行特種處理，使表面硬度達到HRC56~62，具有高耐磨、耐腐蝕的功能。閥瓣密封根據需要時封面均堆焊接有硬質合金，密封面采用線密封，保證密封的可靠性，并可防止結疤。同時，采取短行程閥瓣的設計。在化工、石油、冶金、制藥、農藥、染料、食品加工等行業廣泛使用。各種操作方式，例如，手動，氣動（彈簧復位式，雙作用式、帶手輪和不帶手輪），電動、液動，齒輪等。
Discharge valveMainly used in reactors, storage tanks and other containers at the bottom of row material, by means of the valve at the bottom of flange welded to the bottom of the tanks and other containers, thus removing the process fluid often remains in the container at the bottom of the phenomenon. Discharge valve according to the actual needs of the situation, put the end result is designed to flat-bottomed, valve forVType, and to provide two kinds of work to upgrade and fall of the valve flap. Body cavity with erosion-resistant, corrosion-resistant seals, valve opening moments, you can protect the body from being medium erosion, corrosion, and seals for special processing, the surface hardness toHRC56 ~ 62With high wear and corrosion resistance capabilities. Flap valve cover seals are required when there is carbide reactor welding, sealing surface with thread sealing, to ensure the reliability of sealing and prevents scarring. At the same time, take a short trip valve flap design. In the chemical, petroleum, metallurgy, pharmaceutical, pesticide, dye, food processing and other industries widely used. A variety of operating methods, such as manual, pneumatic (spring reset type, double-acting type, with hand wheel and without hand-wheel), electric, hydraulic, gear and so on.

path scope:25 ~ 250mm
維護保養和安裝使用注意事項
Performance of major equipment
1、 閥門應整體的存放在通風干燥庫房內，嚴禁堆置或露天存放，閥門通徑兩端需板堵塞。
The valve should be kept in ventilated dry the whole warehouse is strictly prohibited, or stacked in open storage, the valve plate diameter at both ends of the need to plug.
2、 安裝前需仔細檢查閥門，并清除閥門內在運輸、存放過程中造成的損害。
Pre-installation required to double-check valve, and clear the valve internal transport, storage process of the damage caused.
3、 在安裝前應注意各部的螺絲受力是否平衡、升降（活動）是否靈活。
Departments should pay attention to before installing the screw force is balanced, lifting (activity) it is flexible.
4、 閥門應安裝在無劇烈震動和沖擊的地方，以及使用閥門無損害的場地。
The valve should be installed in the absence of severe vibration and shock of the place, and the use of the valve without damage to the venue.
5、 當出料受堵塞時，可以使用金屬桿或硬性工具疏通，要注意使用金屬桿或硬性工具不要損害閥瓣和密封圈接觸面。
When a material subject to blocking, you can use the metal bar or a tool to clear hard, pay attention to the use of metal rod or a rigid tool without doing damage to valve and valve seal contact surface.
6、 應盡量避免酸堿介質交替使用（除中和反應介質），以免縮短壽命。
Should try to avoid acid-base media used interchangeably (except in and reaction medium) in order to avoid shortening life expectancy.
7、 根據介質性能及使用期，應經常檢查閥體頂部四氟密封圈和孔板部的四氟薄片。如發現有損壞應及時更換再使用。
According to media performance and the use of period and should always check the valve orifice at the top of the Ministry of PTFE seals and PTFE sheet. If there are damaged should be replaced promptly re-use.
8、 若發現閥門面有損壞時應立即停用，可用專門材料修補患處，或委托有關生產單位生產。
If it is found there is damage to the valve face should be immediately suspended, can be specialized material repair the lesion, or entrust the relevant units of production.
