The high strength and low density of titanium and titanium alloys make them widely used in aerospace engineering. For example, titanium valves are extensively used in various pipelines of aircraft. Currently, with the advancement of science and technology and the increasing use of new materials in various industries, titanium valves have become essential products for various special environments and special fluid transmission systems. Titanium valves can be used to control the flow of various fluids such as air, water, steam, various corrosive media, slurry, oils, liquid metals, and radioactive media, mainly serving to cut off and throttle pipelines.
Titanium valves are forced sealing valves, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface to not leak. When the medium enters the valve from the bottom of the valve disc, the operating force needs to overcome the friction between the valve stem and the packing and the thrust generated by the medium pressure. The force to close the valve is greater than the force to open it, so the diameter of the valve stem must be large, otherwise, bending failure of the valve stem will occur. With the development of self-sealing valves, the flow direction of the medium in the globe valve was changed to enter the valve chamber from the top of the valve disc. At this time, under the action of medium pressure, the force to close the valve is small, and the force to open the valve is large, allowing for the adjustment of the valve stem diameter accordingly. Meanwhile, under the action of the medium, this type of valve is also more tightly sealed.
Titanium valves are floating ball-type air release valves made using Bernoulli's principle, which can remain fully open under the action of airflow. When the solid water column rises, the float ball can immediately float up and seal the air outlet. Titanium valves use a float ball of a specific diameter, producing aerodynamic force that keeps the ball suspended (open) when the airflow passes by, and the buoyancy generated when the solid water column rises causes it to float. An appropriately angled cone is located at the air inlet, ensuring that no matter how high the air pressure or speed, the air outlet will not be blocked.
Ultralight aluminum alloy valve body, small torque, and easy installation. Titanium valves are suitable for air conditioning and industrial water treatment equipment with strong anti-condensation capabilities. The die-cast aluminum alloy body prevents corrosion.
Excellent and durable sealing performance, with a unique multi-level progressive contact valve seat design that allows the valve plate to gradually contact the valve seat during closing. While ensuring good sealing performance, unnecessary torque is reduced, thus extending the valve seat's lifespan.
The reduction in torque results in a lighter and more compact driving device.
Titanium valves have a unique valve stem sealing ring to prevent liquid leakage.
Valve seats made from different materials are suitable for different working conditions, providing good corrosion resistance and sealing performance.
The spherical valve plate's movement trajectory makes the valve rotate flexibly. The valve plate is a complete sphere, and every part of the sealing surface is part of a sphere, including the axial sealing surfaces at the top and bottom of the valve plate. Although the sealing surfaces contact each other during sealing, they are very smooth, thus reducing torque and improving sealing performance, especially reducing the friction at axial sealing points.
