　　Imported slow closing check valve

　　German Ward WODE imported slow closing check valve, also known as check valveIts function is to prevent the backflow of the medium in the pipeline. A valve that opens or closes by the flow and force of the medium to prevent backflow of the medium. Check valves belong to the category of automatic valves and are mainly used in pipelines where the medium flows in one direction. They only allow the medium to flow in one direction to prevent accidents. This type of valve should generally be installed horizontally in pipelines.

The imported slow closing check valve consists of a main valve, a one-way valve, a needle valve, a ball valve, a micro filter, and a pressure gauge to form a hydraulic control valve connection system. By utilizing hydraulic automatic operation, the main valve can achieve optimal opening and closing speeds. To prevent the occurrence of water hammer and achieve the effect of slow closing and noise reduction.

　　working principle

When the valve supplies water from the inlet end, the water enters the main valve control room through a micro filter, needle valve, and one-way valve, and then drains downstream through a ball valve. Because the opening of the needle valve is smaller than that of the ball valve, that is, the drainage speed of the main valve control room is greater than the inlet speed, the pressure in the control room decreases, and the inlet pressure acting on the lower end of the main valve disc opens the main valve to supply water downstream. When the pipeline stops supplying water, if the downstream water starts to flow back, a part of the backflow water enters the main control room through the ball valve. Due to the action of the one-way valve, the backflow water cannot flow out of the main control room, causing the main control room to gradually increase pressure and slowly close the main valve. This product uses hydraulic self control, does not require other devices or energy, is easy to maintain, and has smooth opening and closing. This valve product is widely used in water supply network systems such as high-rise buildings, living areas, and urban water supply projects.

　　Installation and adjustment of imported slow closing check valve:

The optimal installation method for the main valve is to install it horizontally on the pipeline, with the valve cover facing upwards. Other installation methods can also achieve the intended function

2. Before installation, remove any debris from the pipeline. During installation, pay attention to the arrow indicating the water flow outside the main valve body and follow the direction of installation

3. A gate valve and a filter should be installed in front of the main valve, and a gate valve should also be installed behind the main valve for easy maintenance

4. The pipeline must be washed before water supply

5. When testing the water, slowly open the gate valve in front of the main valve, gradually increase the pressure, and pay attention to whether the control pipeline outside the main valve body leaks water

6. The micro filter on the main valve should be cleaned during the main period, and the needle valve and ball valve should be adjusted together to achieve optimal opening and closing speed
