With full size eccentric hemisphere popular new why pneumatic valve?

as the representative of the new type of pneumatic valve ball, eccentric hemisphere structure of pneumatic valve has its unique to some advantages, such as switch frictionless, seal is not easy to wear and open-close torque is small. Which can reduce the distribution of the specifications of the actuator. With multi-turn electric actuators, which can realize to adjust the medium and carefully cut off. Widely used in petroleum, chemical industry, urban water supply and drainage and other demanding cutting conditions.
with all sizes of pneumatic valve and eccentric hemisphere eccentric hemisphere pneumatic valve is now in the market by the strong demand for consumers? What exactly is the character attracted numerous manufacturers rush?
with full size pneumatic valve, eccentric hemisphere is a brand new full size of the structure of the eccentric hemisphere, pneumatic valve diameter and the internal flow is the same as a product, like a normal are reducing manufacture process. Full size eccentric hemisphere pneumatic valve is suitable for the particularly high requirements for traffic conditions, such as oil, chemical industry, electric power, metallurgy, electric power, etc. Adopting integrated full size manufacturing, pneumatic valve port completely open, head loss is zero. Pneumatic valve's sealing is reliable, wear resistance and long service life. Pneumatic ball valve in the open, after the ball crown in pneumatic valve body, without being directly eroded by medium. In addition, the function of automatic clean-up, hard seal eccentric hemisphere pneumatic valve adopts the blade shape of spherical cap edge, can effectively remove pipe fragments.
in addition, the jacket type eccentric hemisphere pneumatic valve has some unique characteristics, meet the necessary requirements of the development of broad areas for China today, which is why this kind of new type of pneumatic valve will rise so rapidly.
. Small pressure loss, wide open water damage is zero, the flow channel unobstructed completely; Lumen automatic cleaning, the core of the pneumatic valve rotating, automatic flushing pneumatic valve body cavity, the medium sundry clean and medium not deposit in the pneumatic valve cavity. Sphere as the hemispherical, circulation with the highest Cv value, to enhance the efficiency of pump system, the abrasion and reduced to a minimum.
. Grain abrasion resistant: using the principle of double eccentric in the process of closing, only by spherical cap at the last minute to tee, without friction; And pneumatic sealing ring wear-resistant self-lubricating alloy surfacing on the seat, not easy to wear and tear, is not easy to wash; Knife mouth ball ball cap and wipe clean and shearing action between the pneumatic valve seat, not easy to scale.
. Automatic compensation reliable sealing: positive pressure, using the principle of eccentric, sphere and pneumatic seat close more and more tightly so as to get a good seal; Back pressure, the floating type pneumatic seat under the effect of compression, the pneumatic valve seat with automatic push-on sphere, the higher the pressure, pneumatic seat to the sphere of more and more tightly, so as to get a good seal; Can keep the lasting tightly sealed, can adapt to the harsh working conditions. Under the long-term use, pneumatic valve seat seal wear or damage, if any, in the spring under the action of pneumatic valve seat with automatic ball tight, so as to get a good automatic compensation function.
. Medium: suitable for high velocity for sphere hidden in the side of the pneumatic valve cavity to form a direct port no flow resistance, strong eccentric crankshaft, fixed at high flow velocity in the medium of no vibration, no noise.
. Long life switch easily: no vulnerable parts, due to the effect of eccentricity, pneumatic ball valve opening and closing process with pneumatic valve seat sealing surface completely out, pneumatic valve seat surface and the spherical cap without bruises do without friction between spherical rotation, effectively reduce the operating torque twist, operating light; Pneumatic valve automatic compensation function, greatly improve the service life of pneumatic valve.
. Easy maintenance: the pneumatic valve jacket type design, spherical cap and a sphere from the pneumatic valve upper load; Maintenance when hoisted out just open the pneumatic valve cover the ball and the ball can be repair and seal ring and other accessories, do not have to keep the whole pneumatic valves unloaded from the pipeline, this to underground pipeline, especially the atomic energy industry ball pneumatic valve to bring great convenience.
. This pneumatic valve in maintenance work at the same time can take into consideration the retention of pipes in the medium, not cause waste of energy; This is free to use many of the early auxiliary work, made maintenance is relatively simple.
. In certain occasions, the pneumatic valve during the period to repair can not affect the normal operation of the pipeline system, as long as the closed flowing rapidly after take out the sphere assembly can be an immediate restoration of pipeline operation under pressure to reduce repair pneumatic valve benefit loss caused to the minimum.
