放料阀主要用于反应器，储罐和其他容器的底部排料，借助于阀门底部法兰焊接于储罐和其他容器的底部，因此消除工艺介质常在容器底部的残留现象。放料阀根据实际情况的需要，放底结果设计为平底，阀体为V型，并提供提升和下降两种工作方式的阀瓣。阀体内腔装有耐冲刷、耐腐蚀的密封圈，在开启阀门瞬间，可以保护阀体不被介质冲刷、腐蚀，并对密封圈进行特种处理，使表面硬度达到HRC56~62，具有高耐磨、耐腐蚀的功能。阀瓣密封根据需要时封面均堆焊接有硬质合金，密封面采用线密封，保证密封的可靠性，并可防止结疤。同时，采取短行程阀瓣的设计。在化工、石油、冶金、制药、农药、染料、食品加工等行业广泛使用。各种操作方式，例如，手动，气动（弹簧复位式，双作用式、带手轮和不带手轮），电动、液动，齿轮等。
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.

维护保养和安装使用注意事项
Performance of major equipment
1、　 阀门应整体的存放在通风干燥库房内，严禁堆置或露天存放，阀门通径两端需板堵塞。
　 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、　 安装前需仔细检查阀门，并清除阀门内在运输、存放过程中造成的损害。
　 Pre-installation required to double-check valve, and clear the valve internal transport, storage process of the damage caused.
3、　 在安装前应注意各部的螺丝受力是否平衡、升降（活动）是否灵活。
　Departments should pay attention to before installing the screw force is balanced, lifting (activity) it is flexible.
4、　 阀门应安装在无剧烈震动和冲击的地方，以及使用阀门无损害的场地。
　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、　 当出料受堵塞时，可以使用金属杆或硬性工具疏通，要注意使用金属杆或硬性工具不要损害阀瓣和密封圈接触面。
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、　 应尽量避免酸碱介质交替使用（除中和反应介质），以免缩短寿命。
　Should try to avoid acid-base media used interchangeably (except in and reaction medium) in order to avoid shortening life expectancy.
7、　 根据介质性能及使用期，应经常检查阀体顶部四氟密封圈和孔板部的四氟薄片。如发现有损坏应及时更换再使用。
　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、　 若发现阀门面有损坏时应立即停用，可用专门材料修补患处，或委托有关生产单位生产。
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.
