The paper disc pneumatic valve structure design of main parts

and diversion box welding. On face for Φ mm size, valve pneumatic valve and connection of diversion box form for welding. Interface under transverse size of Φ mm. With the flange welding. At the same time in order to decrease the difficulty of style in the whole system created to facilitate valve pneumatic valve installation, pneumatic valve body for special-shaped structure. Request of end face diameter from gradually transition to the upper end face diameter Φ Φ mm mm, upper and lower two end face are circular, and upper and lower the Angle between the two end face for °.
the paper disc pneumatic valve structure design of the main parts of the


valve pneumatic valve structure design of the 3 D CA D complete UnigraphicsNX environment, & lt; Valve pneumatic valve structure design in the 3 D CA D UnigraphicsNX environment. Damping arm and a heavy hammer and the center of gravity of the rolling elements, weight and movement parameters can be by CA D software solution by means of three dimensional CA D software, for valve pneumatic valve of a few moment balance calculation and analysis on the limit position. In order to make the pneumatic valve open and closed within the designated premise parameters, required by repeated trial, step by step to determine location and dimensions of the disc rolling pneumatic valve components. Design calculation, to accept the pressure, strong shear force and the stress concentration of part of the strength calculation and checking.

pneumatic valve body parts of pneumatic seat and USES the bolt connection between the flange, pneumatic valve body parts by pneumatic valve, flange, and pneumatic sealing gasket seating, etc. The flange welding on the pneumatic valve body. Middle device graphite entanglement keep seal gasket. Parts

damping arm damping arm parts by damping arm axis, damping, damping, baffle plate and pneumatic valve and other parts.
with the damping arm around rolling bearing axis, damping arm components are installed on the bearing axis. Pneumatic valve shaft by damping and damping force arm together. So as to achieve the purpose of the open or closed
it can adjust the size and number, damping piece is fixed on the lower end of the damping arm by bolts. In order to adjust the damping arm parts quality and center of gravity position, makes the valve pneumatic valve closed and open differential pressure can be adjusted. In addition, the movement process of damping piece in a closed fluid resistance effect, can reduce valve pneumatic valve closed at a certain level of water hammer effect. Block slice with damping arm through a pin shaft link. When block slice in contact with the pneumatic valve body in appearance, the damping arm block slice can prevent components inherit the open direction, to ensure that the valve pneumatic valve in the open position when the Angle of the largest °.
this makes contacts with pneumatic pneumatic valve seat valve, pneumatic valve and damped axis between the ball joint connection. Has a certain degree of freedom, can make small adjustments, the pneumatic valve with pneumatic seat contact is good, insist on sealing function.

heavy hammer parts weight and pressure difference of rotating shaft torque will be greater than the valve pneumatic valve weight of shaft torque, heavy hammer parts is mainly composed of a heavy hammer, adjust the connecting rod, a heavy hammer bracket and positioning block and other parts. Heavy hammer parts when the system is the function of differential pressure reaches a certain value. Under the pressure difference of smaller closed. When the spin valve pneumatic valve to a certain Angle, heavy hammer out with damping arm, reducing valve, pneumatic valve weight so as to reduce the impact of the pneumatic valve with pneumatic valve body, advances the reliability of the closed. The diameters of the heavy hammer damping adjustable arm free trip. A heavy hammer bracket to support a heavy hammer. Heavy hammer rod can adjust the weight in the relative position of scaffolding, thereby achieve fine-tuning for adjustment, will support made removable structure.
locking and positioning
must consider the bolt and the adjusting mechanism of locking and positioning. Pneumatic valve seat and the connection between the flange bolts under all adopt the locking washers, because valve pneumatic valve placed within the heap. In order to prevent the bolt slack off. Connection and fixation effect of bolt, screw, nut, and a shaft, adopts the way of fixed announces the pin. With adjusting bolts and nuts, finished, must be adjusted in the valve pneumatic valve adopts the way of fixed announces the pin again. Indicator

position valve pneumatic valve needs to be set on the pneumatic valve position indicator, because valve pneumatic valve installed in the reactor pool below the surface. In real time monitoring of valve pneumatic valve open or closed position. Valve pneumatic valve position indicator for the reed pipe. Permanent magnets installed in damping the arm on the parts of a piece damping, with the roll damping arm, built-in indicator of the dry reed pipe sensing device is fixed on the pneumatic valve body. When damping arm movements, the damping of permanent magnets with the movement, through the corresponding circuit connected when dry reed pipe, thus monitoring valve pneumatic valve position.
