一、进口黄铜闸阀产品详情：

德国《LOCKE》洛克--进口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。

二、进口黄铜闸阀技术参数：

公称通径：DN15-DN100

公称压力：1.6Mpa

适用温度：-20℃～150℃

适用介质：水、油、气

阀体材质：黄铜，青铜

连接方式：丝扣螺纹

传动方式：手轮

螺纹标准：ISO 228

三、进口黄铜闸阀工作原理：

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。本系列阀门阀体为黄铜材质。

四、进口黄铜闸阀性能特点：

1、流动阻力小。阀体内部介质通道是直通的，介质成直线流动，流动阻力小;

2、启闭时较省力。是与截止阀相比而言，因为无论是开或闭，闸板运动方向均与介质流动方 向相垂直;

3、高度大，启闭时间长。闸板的启闭行程较大，降是通过螺杆进行的;

4、水锤现象不易产生。原因是关闭时间长;

5、介质可向两侧任意方向流动，易于安装。闸阀通道两侧是对称的;

6、结构长度(系壳体两连接端面之间的距离)较小。

1、 Details of imported Brass Gate Valves:

The imported gate valve is a control part in the pipeline system that moves along the channel axis vertically through the hand wheel to cut off the medium flow. In the process of use, the valve must be fully open or closed, and can not be used to adjust the flow.

2、 Technical parameters of imported Brass Gate Valve:

Nominal diameter: DN 15-dn 100

Nominal pressure: 1.6Mpa

Applicable temperature: - 20 ℃ ~ 150 ℃

Applicable media: water, oil and gas

Body material: brass, bronze

Connection mode: screw thread

Transmission mode: hand wheel

Thread standard: ISO 228

3、 Working principle of imported Brass Gate Valve:

The 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 brass.

4、 Performance characteristics of imported Brass Gate Valve:

1. The flow resistance is small. The medium channel inside the valve body is straight, the medium flows in a straight line, and the flow resistance is small;

2. It is easy to open and close. Compared with the stop valve, because whether it is open or closed, the movement direction of the ram is perpendicular to the flow direction of the medium;

3. High height, long opening and closing time. The opening and closing stroke of the ram is large, and the lowering is carried out through the screw;

4. Water hammer is not easy to occur. The reason is the long closing time;

5. The medium can flow to both sides in any direction, easy to install. Both sides of gate valve passage are symmetrical;

6. The structure length (the distance between the two connecting ends of the shell) is small.
