Check valve works and common troubleshooting methods

The primary function of this type of valve is to allow the flow of a medium in only one direction, while preventing reverse flow. These valves typically operate automatically, with the valve disc opening when fluid flows in the correct direction due to pressure. However, when the flow attempts to move in the opposite direction, the disc is pushed back into place by both the fluid pressure and its own weight, effectively closing the passage. This type of valve is commonly referred to as a check valve, and it includes two main types: the swing check valve and the lift check valve. In a swing check valve, the disc is hinged and rests against a slanted seat. The design ensures that the disc swings open smoothly and returns to the correct seating position each time. The hinge mechanism allows for sufficient movement so that the disc makes full contact with the seat, ensuring a tight seal. The disc can be made entirely of metal or may feature a leather, rubber, or synthetic covering, depending on the application requirements. When fully open, the swing check valve offers minimal resistance to fluid flow, resulting in a relatively low pressure drop across the valve. On the other hand, a lift check valve has a disc that moves vertically within the valve body. The disc lifts off the seat when fluid flows in the correct direction and falls back down under the force of gravity or fluid pressure when flow reverses. Similar to 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 a lift check valve is generally lower than that of a swing check valve. Common issues with check valves include broken discs and media backflow. A broken disc often occurs when the pressure on both sides of the valve becomes nearly equal, causing the disc to oscillate and eventually break, especially if it's made from brittle materials like cast iron or brass. To prevent this, it's advisable to use check valves constructed from more durable materials. Media backflow can result from damaged sealing surfaces or the presence of foreign particles. To address this, the sealing surface should be repaired or replaced, and any impurities should be removed to ensure proper operation. Regular maintenance and inspection are essential to keep check valves functioning efficiently and reliably.

Industrial Steel Buildings

Industrial steel structure buildings have a wide range of uses, and the high cost performance is worth choosing!
Industrial steel structure buildings are used in various industries, and their construction is convenient, and different steel structure buildings can be designed, which can also meet the needs of daily factories. Let's introduce the specific advantages of using steel structure buildings.

Wide range of uses
The scope of application of industrial steel structure buildings is still very wide. In addition to the use of factories as Steel Structure Workshop, some daily storage centers use Steel Structure Warehouse as warehouse, as well as gymnasiums, dormitories, etc., are actually buildings that can use steel structures. And not only the ground floor can be built, as long as the design is reasonable, then high-rise and multi-storey buildings can be constructed and applied.

Simple construction
Compared with traditional building construction, the construction of the steel structure itself is very simple, and all components are prefabricated and have certain standard sizes, which can be installed directly. The construction efficiency is high, and the construction of the plant can be completed in a short time. And generally it can be directly spliced, which greatly shortens the construction time, and the construction of large-scale buildings can be completed in less than one month.

High durability
Industrial steel structure buildings can be used for a long time, not just temporary use for a month or two, and the stability of the steel structure is also guaranteed. Moreover, the daily maintenance of the building is simple, and the design and construction of the building can be completed directly through computer design. Even if it is used in bad weather, there will be no problems, and it is suitable for long-term use.

beautiful and practical
Steel structure buildings come in many different colors, and manufacturers can also provide customized processing services. The design of the building is simple and beautiful, and it can also be decorated internally. Such a building has strong flexibility in use and can meet the requirements of different projects for long-term use.

Cost discount
Industrial steel structure buildings are light in weight, and the price of steel structures is favorable, and the cost performance is still good. Because of the high construction efficiency of its buildings, labor costs are also very cost-effective. It only needs to complete the design and construction, and the building can be put into use immediately, and the overall cost performance is also good.
