进口高压止回阀(进口止回阀***)德国奥莱斯
【进口高压止回阀】详细说明：
高压止回阀有非金属密封和金属密封两种，主要用于油矿钻井泥浆循环系统设备，控制水、油、泥浆、聚合物、粘土胶、***等管线的流通与关闭，适用于压力16.0MPa～40.0MPa，工作温度≤121℃。
High-pressure check valves h***e two kinds of non-metallic and metal seals. They are mainly used in oil drilling mud circulating system equipment to control the circulation and closure of pipelines such as water, oil, mud, polymer, clay glue and natural gas. They are suitable for pressure 16.0 MPa to 40.0 MPa and working temperature less than 121 C.
产品工作原理：
高压直通式单向阀阀瓣通过弹簧的压缩变形来增加阀瓣的密封预紧力，使初始密封更加可靠，当进口端介质压力大于弹簧的压缩力时，阀瓣向开启方向移动，此时阀门打开，流体通过支架的导流槽流入阀后；而当进口端压力降低时，阀瓣封闭，再加上介质回流的压力，使阀瓣比压达到密封要求而形成密封。
High-pressure through one-way valve disc through the compression deformation of the spring to increase the sealing preload of the disc, making the initial seal more reliable. When the pressure at the inlet end is greater than the compression pressure of the spring, the disc moves towa*** the opening direction, when the valve opens, the fluid flows into the valve through the guide groove of the support; and when the pressure drop at the inlet end is greater than the compression pressure of the spring, the disc moves towa*** the opening direction. When the valve is low, the valve disc is closed, coupled with the pressure of medium reflux, so that the specific pressure of the valve disc meets the sealing requirements and forms a seal.
产品特点：
1、可直通或立式安装（安装方便）。
2、上、下阀体用螺纹连接。成流线造型，造型美观。
3、适用于压力为10-40MPa的管道，密封性能可靠，经久耐用。
4、阀门阀瓣、阀座密封面堆焊司太立合金，高硬度经久耐用，***。
5、内部结构弹簧加载直通式，阀门在开启和关闭中无噪音，流体运动方向改变小，压力损失少，减少水锤，经济节能。
1. It can be installed directly or vertically (easy to install).
2. The upper and lower valve bodies are connected by threads. Streamlined shape, beautiful shape.
3. It is suitable for pipelines with pressure of 10-40 MPa. Its sealing performance is reliable and durable.
4. Surfacing Stellite alloy on valve disc and seat sealing surface, high hardness and durability, never wear and tear.
5. Internal structure spring-loaded through type, no noise in the opening and closing of the valve, little change in the direction of fluid movement, less pressure loss, less water hammer, economic and energy s***ing.
