产品描述：

德国洛克-进口污水复合式排气阀是专用污水管道工程的排气阀，与复合式排气阀原理一样，只是结构略作改动，杠杆机构稍有改进（把浮球控制在下部，使污物只能在阀体下部物污不会缠绕上部排气口上，不会影响密封性能。

The German locke imported sewage compound exhaust valve is the exhaust valve of special sewage pipeline engineering. The principle of the compound exhaust valve is the same as that of the composite exhaust valve, but the structure is slightly modified, and the lever mechanism is slightly improved (the floating ball is controlled at the lower part of the valve body, so that the dirt can only be on the lower part of the valve body, and the dirt will not be entangled on the upper exhaust port, and the sealing performance will not be affected.

产品工作原理：

管内污水在运作时，该阀活瓣停在定位架下部，进行大量排气，当空气排完时，污水进入阀内，球浮起，传动活瓣到关闭，停止排气。管内在运作时会自然产生少量气体，这些气体会集中到管内上部，到相当程度，阀内污水下降，浮球顺水下降，气从小孔排出。如出现停电、停泵，管内水流空时随时出现负压，浮球顺水下降，打开小孔带动大孔进行大量补气，确保管道安全。

When the sewage in the pipe is in operation, the valve of the valve stops at the lower part of the positioning frame for a large amount of exhaust. When the air is exhausted, the sewage enters the valve, the ball floats, and the valve is driven to close, and the exhaust is stopped. A small amount of gas will naturally be generated during the operation of the pipe. These gases will be concentrated in the upper part of the pipe. To a certain extent, the sewage in the valve will drop, and the floating ball will drop along the water, and the gas will be discharged from the small hole. In case of power failure and pump shutdown, negative pressure will appear at any time when the water flow in the pipe is empty, and the floating ball will drop along the water. The small hole will be opened to drive the large hole to make a large amount of air to ensure the safety of the pipeline.

产品性能及优点：

1、浮球控制在下部，使污物只能在阀体下部污物不会缠绕上部排气口上，不会影响密封性能。

2、本产品是专用污水管道工程的排气阀。

3、浮球为不锈钢，使用寿命长，***。

4、能够排除管道中的气体，减少阻力，节约能源。

5、当管道负压时，能快速自动吸气，防止管道破裂。

1. The floating ball is controlled in the lower part, so that the dirt can only be in the lower part of the valve body, and the dirt will not wrap around the upper exhaust port, which will not affect the sealing performance.

2. This product is the exhaust valve of special sewage pipeline engineering.

3. The floating ball is made of stainless steel, with long service life, safe and reliable.

4. It can remove the gas in the pipeline, reduce the resistance and save energy.

5. When the pipeline is under negative pressure, it can quickly and automatically aspirate to prevent the pipeline from breaking.

管道内气体产生的原因：

1、在管道安装完毕后 通水之前，管道内充满了空气。

2、水在水泵工作前后因压力发生较大的变化而出现气体。

3、管道系统内部水温发生变化，产生空气。

4、水在通过管道的一些附件，如阀门、三通、.弯头等，由于水压力发生较大变化，会产生气体。

5、管道系统的渗漏 。

6、管道维修.维护时，管道泄水或水锤等工作情况产生的负压进气。

1. After the installation of the pipeline, the pipeline is filled with air before water is supplied.

2. Water in the pump before and after the work due to a greater change in pressure and gas.

3. The water temperature inside the pipe system changes and produces air.

4. When water passes through some accessories of the pipeline, such as valves, tees, elbows, etc., gas will be produced due to large changes in water pressure.

5. Leakage of piping system.

6. Negative pressure air intake caused by pipeline drainage or water hammer during pipeline repair and maintenance.
