一、进口不锈钢闸阀产品介绍：

德国《LOCKE》洛克--进口不锈钢闸阀是一个启闭件闸板，闸板的运动方向与流体方向相垂直，闸阀只能作全开和全关。闸阀关闭时，密封面可以只依靠介质压力来密封，即只依靠介质压力将闸板的密封面压向另一侧的阀座来保证密封面的密封，这就是自密封。大部分闸阀是采用强制密封的，即阀门关闭时，要依靠外力强行将闸板压向阀座，以保证密封面的密封性。本系列阀门阀体为不锈钢材质，可用于带有酸碱性介质中。

二、进口不锈钢闸阀工作原理：

进口不锈钢闸阀是管路系统中通过手轮转驱闸板沿通道轴线垂直方向移动切断接通介质流的控制部件，在使用过程中，阀门必须是全开或全关，不能用作调节流量。

6、可采用各种配管法兰标准及法兰密封面形式，满足各种工程需要及用户要求。

1、 Product introduction of imported stainless steel gate valve:

The imported stainless steel gate valve is a gate with opening and closing parts. The movement direction of the gate valve is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed. When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, only rely on the medium pressure to press the sealing surface of the gate valve to the seat on the other side to ensure the sealing surface, which is self sealing. Most gate valves are forced to seal, that is, when the valve is closed, the gate should be forced to the valve seat by external force, so as to ensure the tightness of the sealing surface. The valve body of this series is made of stainless steel, which can be used in acid-base medium.

2、 Working principle of imported stainless steel gate valve:

The imported stainless steel gate valve is a control component in the pipeline system, which can cut off the medium flow through the vertical movement of the gate along the channel axis through the hand wheel. In the process of use, the valve must be fully open or closed, and can not be used to adjust the flow.

3、 Performance characteristics of imported stainless steel gate valve:

1. Excellent material selection, in line with the relevant standards at home and abroad, the overall quality of materials is high;

2. It meets the requirements of advanced standards at home and abroad, with reliable sealing, excellent performance and beautiful appearance;

3. The sealing pairs are advanced and reasonable. The sealing surfaces of gate and valve seat are overlaid with Stellite Co based cemented carbide with different hardness. The sealing is reliable, high hardness, wear resistance, high temperature resistance, corrosion resistance, good scratch resistance and long service life;

4. After quenching and tempering and surface nitriding treatment, the valve stem has good corrosion resistance, abrasion resistance and abrasion resistance;

5. Wedge type elastic gate structure is adopted, thrust bearing is set in medium and large diameter, friction force is small, and impact handwheel is equipped, opening and closing is easy and free;

6. All kinds of piping flange standards and flange sealing surface forms can be adopted to meet various engineering needs and user requirements.
