ASCO solenoid pneumatic valve performance

aska ASCO solenoid pneumatic valve is applied to automatic control system. Many different kinds of electric actuator, in the way of action in different ways, such as Angle of travel Angle to the electric actuator is the output torque, and straight travel electric actuator is the output displacement of the thrust. Electric actuators in the system application of variety, should be selected to meet the need of pneumatic valve operation. The connection forms of pneumatic valve used most frequently. Aska ASCO solenoid pneumatic valve according to the joint surface shape can be divided into the following kinds: smooth type: used for pneumatic valve pressure is not high. Processing more convenient; Lenticular: high work pressure, can be used in hard washer; Mortise type: plastic deformation is larger washers are available, and in the corrosive medium is used more widely, the sealing effect is better. Trapezoidal groove: with oval metal ring gasket, used to the work pressure of kg/cm2 or pneumatic valve, pneumatic valve or high temperature. Lens: the washer is lens shape, made of metal. For work pressure of kg/cm2 or high pressure pneumatic valves, pneumatic valves or high temperature. O-ring type: this is a relatively new form of flange connection, aska ASCO solenoid pneumatic valve is with the emergence of a variety of rubber o-ring, and developed, it in a sealed connection.
aska ASCO solenoid pneumatic valve sealing ring with the cone, with medium relative to one side with a certain Angle, within the medium pressure to the cone, and passed to the sealing ring, on the cone Angle, two component, a parallel to the center line of the pneumatic valve body, the outward pressure pneumatic valve body wall to another. This component is the force behind. The more the greater the medium pressure, since the tight force is big. So this kind of connection form, aska ASCO solenoid pneumatic valve is suitable for high pressure pneumatic valves. Than the flange connection, to save a lot of material and manpower, but also need a certain pre-tightening force, in order to pressure pneumatic valve is not high, the use of reliable. Using the close sealing principle of pneumatic valves, is generally high pressure pneumatic valves. Aska ASCO solenoid pneumatic valve connection form also many, for example, some do not have to dismantle the small pneumatic valves, together with the pipe welding; Some non-metallic pneumatic valve, use socket type connection, and so on. Pneumatic valve users according to Hugh situation specific treatment.
aska ASCO solenoid pneumatic valve in the greasing operation, on the pressure changes regularly with peak valley. Pressure is too low, seal leakage or failure, the pressure is too high, greasing the jams, seal inside lipid hardening or seal and pneumatic ball valve, pneumatic valve plate lock. Aska ASCO solenoid pneumatic valve usually fat injection pressure too low, injecting grease into the pneumatic valve at the bottom of the cavity, more commonly occur in small brake pneumatic valve. And fat injection pressure is too high, on the one hand, to check on the mouth, so fat pore blocking determine to change the situation; Is lipid hardening on the other hand, to use cleaning fluids, repeated failure sealing grease of softening, and inject new replacement grease. In addition, aska ASCO solenoid pneumatic valve sealing type and sealing material, also influence on the pressure, different seal forms have different fat injection pressure, in general, hard seal fat injection pressure is higher than the soft seal.
