Copper Rotary Screw Check Valve

The valve body of the copper swing thread check valve manufactured by Shengshi Huagong is made of high-quality copper, which has good casting performance and can be accurately cast into complex shapes to meet the design requirements of the internal flow channel of the valve. Threaded connection is one of the notable features of this valve. The valve has internal or external threads at both ends, which are screwed together with the corresponding external or internal threads on the pipeline to achieve tight installation of the valve and the pipeline. This connection method has the advantages of easy installation and disassembly, and does not require additional welding or flange connection tools. It has obvious advantages in some pipeline systems with limited space or frequent disassembly and maintenance.

Product advantages

(I) Compact installation structure

The check valve adopts a threaded connection method, which makes the installation structure of the copper thread check valve very compact. Compared with flange-connected valves, it does not require additional flanges and longer connecting bolts, greatly shortening the overall length of the valve. In scenarios where installation locations are limited, such as building pipe wells and narrow spaces inside equipment, this compact structure can be easily adapted, reducing the requirements for installation space and also reducing the overall space occupied by the pipeline system. For example, in pipeline renovation projects in some old buildings, where the space is narrow, the copper wire check valve can be installed smoothly with its compact structure without destroying too much of the original building structure, providing convenience for the upgrade and renovation of the pipeline system.

(II) Good sealing performance

The high-precision fit between the valve disc and the valve seat and the possible auxiliary sealing materials (such as rubber gaskets) give the valve excellent sealing performance. When the valve is closed, the valve disc is tightly pressed against the valve seat under the backflow pressure of the medium and its own gravity, forming a reliable sealing surface to effectively prevent medium leakage. Even under working conditions with large pressure fluctuations, the sealing structure between the valve disc and the valve seat can automatically adjust the sealing pressure, always maintain a good sealing effect, and meet the needs of various pipeline systems with strict sealing requirements. For example, in some chemical production processes, the medium pressure in the pipeline is unstable, and the copper wire check valve can stably maintain the seal, prevent the leakage of corrosive media, and ensure production safety and environmental safety.

(III) Efficient check performance

The valve disc of the copper wire check valve is reasonably designed and responds quickly. When the flow direction of the medium changes, the valve disc can be closed in a very short time, effectively cutting off the medium reflux channel and preventing a large amount of medium from flowing back. Its fast closing speed can significantly reduce the risk of damage to the equipment in the pipeline system caused by medium backflow, such as avoiding reverse damage to the pump and preventing the pressure equipment from overpressure due to medium backflow, etc., providing a strong guarantee for the safe and stable operation of the pipeline system. In some industrial production lines that have extremely high requirements for fluid delivery continuity, the efficient check performance of the copper wire check valve can ensure that the production process is not disturbed by the backflow of the medium, thereby improving production efficiency.

(IV) Easy operation and maintenance

The threaded connection method makes the installation and removal of the valve extremely convenient. During installation, you only need to use ordinary wrenches and other tools to tighten the threads of the valve and the pipe; when maintaining or replacing the valve, you can also easily remove it from the pipe. In addition, the internal structure of the valve is relatively simple, with a small number of parts, which is easy to inspect and repair. Daily maintenance work mainly includes regular inspections of the sealing condition of the valve disc and the valve seat, the movement flexibility of the valve stem, and whether the threaded connection is loose. The operation is simple, which reduces the maintenance cost and difficulty. For some small businesses or home users, the easy maintenance characteristics of the copper wire check valve make it an ideal choice. Users can perform simple maintenance operations by themselves without the need for professional maintenance personnel.
