放料閥主要用于反應(yīng)器，儲(chǔ)罐和其他容器的底部排料，借助于閥門底部法蘭焊接于儲(chǔ)罐和其他容器的底部，因此消除工藝介質(zhì)常在容器底部的殘留現(xiàn)象。放料閥根據(jù)實(shí)際情況的需要，放底結(jié)果設(shè)計(jì)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(nèi)腔裝有耐沖刷、耐腐蝕的密封圈，在開啟閥門瞬間，可以保護(hù)閥體不被介質(zhì)沖刷、腐蝕，并對(duì)密封圈進(jìn)行特種處理，使表面硬度達(dá)到HRC56~62，具有高耐磨、耐腐蝕的功能。閥瓣密封根據(jù)需要時(shí)封面均堆焊接有硬質(zhì)合金，密封面采用線密封，保證密封的可靠性，并可防止結(jié)疤。同時(shí)，采取短行程閥瓣的設(shè)計(jì)。在化工、石油、冶金、制藥、農(nóng)藥、染料、食品加工等行業(yè)廣泛使用。各種操作方式，例如，手動(dòng)，氣動(dòng)（彈簧復(fù)位式，雙作用式、帶手輪和不帶手輪），電動(dòng)、液動(dòng)，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.

維護(hù)保養(yǎng)和安裝使用注意事項(xiàng)
Performance of major equipment
1、　 閥門應(yīng)整體的存放在通風(fēng)干燥庫(kù)房?jī)?nèi)，嚴(yán)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(xì)檢查閥門，并清除閥門內(nèi)在運(yùn)輸、存放過(guò)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(yīng)注意各部的螺絲受力是否平衡、升降（活動(dòng)）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(yīng)安裝在無(wú)劇烈震動(dòng)和沖擊的地方，以及使用閥門無(wú)損害的場(chǎng)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(dāng)出料受堵塞時(shí)，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(yīng)盡量避免酸堿介質(zhì)交替使用（除中和反應(yīng)介質(zhì)），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(jù)介質(zhì)性能及使用期，應(yīng)經(jīng)常檢查閥體頂部四氟密封圈和孔板部的四氟薄片。如發(fā)現(xiàn)有損壞應(yīng)及時(shí)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(fā)現(xiàn)閥門面有損壞時(shí)應(yīng)立即停用，可用專門材料修補(bǔ)患處，或委托有關(guān)生產(chǎn)單位生產(chǎn)。
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.
