Check valve works and common troubleshooting methods

The primary function of this type of valve is to permit the flow of a medium in only one direction while preventing reverse flow. These valves typically operate automatically, with the valve disc opening under the pressure of the flowing medium in the correct direction. When the flow attempts to reverse, the disc is pushed back into place by both the fluid pressure and its own weight, effectively closing the passage. This category includes two common types: swing check valves and lift check valves. Swing check valves feature a hinged mechanism that allows the disc to swing open and close. The disc rests against a slanted seat surface and is designed to ensure proper seating each time. The hinge mechanism provides sufficient clearance for the disc to fully contact the seat, ensuring a tight seal. The disc can be made entirely of metal or may include a leather, rubber, or synthetic cover depending on the application requirements. In the fully open position, the flow experiences minimal resistance, resulting in a relatively low pressure drop across the valve. Lift check valves, on the other hand, have a disc that moves vertically within the valve body. The disc lifts off the seat when the flow is in the correct direction and returns to the seat when the flow reverses. Like a gate valve, the flow path through a lift check valve is more restricted, leading to a higher pressure drop compared to a swing check valve. Additionally, the flow capacity of lift check valves is generally lower due to the narrower passage. Common issues with check valves include valve disc failure and media backflow. A broken disc often occurs when the pressure on both sides of the valve is nearly balanced, causing the disc to rock or flutter. This is particularly common with brittle materials like cast iron or brass. To prevent this, it's recommended to use check valves made from tougher materials. Backflow can occur due to damaged sealing surfaces or the presence of foreign particles. Repairing the sealing area and cleaning the valve can help restore proper operation and prevent unwanted reverse flow. Regular maintenance and inspection are essential to ensure reliable performance over time.

Customizable Series Products

How to make a request for a custom Container House? What details need attention?
Container houses can be customized and processed according to our needs. Size specifications, internal area divisions, and appearance styles can also be customized and processed. There are many different types of container houses that can be customized according to consumer needs. Custom processing. But how to put forward the corresponding requirements when customizing? What details should be paid attention to when customizing?

The overall design should be reasonable
In order to ensure the practicality of the container house, it is necessary to do a good job in the overall design when customizing the Prefabricated House. The customizable series of products need to take into account the specific floor area, internal volume, how much internal space is required, how to divide the area, etc. Generally, it is necessary to conduct on-site inspections, and to reserve the location of the corridor, etc. If the container house is used in the moving area of the construction site, then it is also necessary to ensure that the corresponding transportation channel is reserved to facilitate the staff to walk back and forth, and also to carry goods, etc., the design It is still necessary to ensure that it conforms to the situation on the spot.

Pay attention to material selection
The customizable series of products include a variety of product types. In addition to container houses, there are also custom container houses, custom light steel villas, etc. It is recommended to pay attention to the overall material of the custom. Different, the service life will definitely be affected as well. Therefore, we still have to pay attention to the specific conditions of its material. Generally, it is recommended to look at the actual product, pay attention to whether the cross section is uniform, and whether the thickness of the steel plate and the thickness of the coating are guaranteed. Moreover, we cannot ignore the details of the supporting frame, connectors and other details. We must ensure that the quality of each component is excellent, so that the container house can be used for a long time and its reliability is guaranteed.

Adjustments to blueprints
Customizable series of products may require multi-layer design, so it is recommended to make a request when customizing, and then the manufacturer will provide us with the corresponding design. If there are certain details that need to be adjusted on the design drawing, it must be completed quickly. Adjust, and then go for post-customization. Manufacturers will have their own design team, and after confirming that there are no problems in the design, they can proceed to construction.
