The sealing mechanism of the Threaded Cartridge Valve is exquisitely designed to ensure excellent sealing performance under high pressure, high flow and vibration environments. The following is a brief description of its sealing mechanism design:
Sealing surface design
The Threaded Cartridge Valve usually uses a conical surface or a spherical cone surface as the sealing surface. This design can form a close line contact or point contact, effectively reducing the leakage channel. The angle and accuracy of the conical surface or the spherical cone surface are carefully calculated and optimized to ensure that sufficient sealing force can be generated under high pressure while reducing friction and wear.
Sealing material selection
The selection of sealing materials is crucial to the sealing performance of the Threaded Cartridge Valve. Under high pressure, high flow and vibration environments, the sealing material needs to have good wear resistance, corrosion resistance, high temperature resistance and good elastic recovery ability. Common sealing materials include rubber, polytetrafluoroethylene (PTFE), metal sealing rings, etc. These materials can be selected according to the needs of different working conditions to ensure the stability and reliability of the sealing effect.
Threaded connection and tightening
Threaded Cartridge Valve is directly installed on the oil circuit board of the hydraulic system through threaded connection. This connection method not only simplifies the installation process, but also improves the integration of the system. In order to ensure the sealing effect, the threaded connection part is usually made of high-strength materials, and is precision-processed and strictly quality-controlled. During the tightening process, it is necessary to tighten according to the specified torque to ensure the tightness and stability of the threaded connection.
Auxiliary sealing structure
In addition to the above-mentioned main sealing mechanism, Threaded Cartridge Valve may also use some auxiliary sealing structures to further improve the sealing performance. For example, O-rings or sealing rings are set around the sealing surface to increase the redundancy and reliability of the seal. These auxiliary sealing structures can provide additional sealing barriers to prevent medium leakage when the main sealing surface fails.
In summary, Threaded Cartridge Valve has an excellent sealing mechanism through precise sealing surface design, appropriate sealing material selection, reliable threaded connection and tightening, and the use of auxiliary sealing structures. This mechanism can maintain good sealing performance under high pressure, high flow and vibration environments to ensure the stable operation of the hydraulic system.
