鈥婬ow to make the ceramic ball valves have an extremely long service life
How to make the ceramic ball valves have an extremely long service life? First of all, we need to understand the working principle of the ceramic double-gate discharge valve, and then clearly define his installation and use points.
Ceramic double gate discharge valve working principle
The working process of the ceramic double-gate discharge valve is that when the ceramic double-gate discharge valve air source is introduced from the upper air inlet, the ceramic double-gate discharge valve stem drives the valve plate to move downward, and the valve is closed. When the air source is introduced from the lower air inlet, the valve stem drives the valve plate to move upward and the valve opens. A spring is loaded between the valve plate and the valve seat, and the spring force always presses the valve plate against the valve seat to ensure the sealing of the valve, and allows the valve plate to move vertically in the vertical direction, which helps to compensate for the thermal expansion and contraction of the valve parts, and It can overcome any influence of back pressure changes on the seal and prevent the particulate medium from entering between the two sealing faces.
During the opening and closing process, the valve plate can rotate, which causes grinding and polishing between the sealing surfaces. Moreover, due to the eccentricity of the valve body to the channel, eddy current is generated when the material is opened and discharged, and the formed material vortex will clean the valve by itself. Inner cavity. All the characteristics of the ceramic double-gate discharge valve make this valve have an extremely long service life, which provides a reliable guarantee for the safe operation of your system.
Ceramic double gate discharge valve installation and use points
1. The ceramic double-gate discharge valve should be read carefully before installation and check the valve type, diameter and technical parameters.
2. It is forbidden to apply the welding flange after installing the valve to avoid damage to the ceramic double gate discharge valve sealing ring. The installation distance of the ceramic double-gate discharge valve reserved from the pipeline should be appropriate, and the flanges should be shimmed on both sides.
3. The center of the two pipes and the center of the valve should be coaxial. The flange surface should be flat. The flange surface should not be deflected to ensure the clamping and normal operation of the valve. Tighten the bolts so that they are evenly symmetrical.
