A kind of novel butterfly plate safety check is mainly made up of component such as valve body, valve shaft, butterfly plate, oil control device, air-control device, butterfly plate open and close state electric signaling devices; Valve shaft and butterfly plate are arranged on valve body, on valve body, be also provided with source of the gas and process three positions, oil control device is arranged on valve shaft, oil control device is connected with valve shaft by spacing open tubular column, is provided with blade on valve shaft, on spacing open tubular column, is provided with oil cylinder, oil cylinder is divided into A chamber and B chamber by blade, oil-storing barrel is connected with A chamber by oil pipe, and B chamber is connected with a small ball by oil pipe, and small ball is connected by oil pipe with oil-storing barrel; Air-control device connects cylinder by solenoid valve by air pipe one end, the other end connects source of the gas and processes three linked piece composition, source of the gas processing three linked piece is arranged on source of the gas and processes on three positions, and source of the gas is processed three linked piece and is composed in series by moisture trap, reduction valve, pressure regulator, pressure gauge, mist of oil regulator and oil sprayer; In cylinder, be provided with piston, on piston, be connected with piston rod, between piston rod and pivoted arm, be provided with twin adapter; Cylinder one end is connected with support, is provided with butterfly plate open and close electrical signal position limit switch and butterfly plate start-stop position limit switch on support.
The design's oil control device working principle is as follows:
When valve shaft rotates counterclockwise, butterfly plate is opened, and at this moment blade is flapped toward B chamber, and the damping oil in B chamber unhinderedly returns to oil storage cylinder, and in this process, blade is to work under the state of micro-resistance, and butterfly plate is opened smoothly.
When valve shaft clockwise rotates, butterfly plate is closed, at this moment blade is flapped toward A chamber, thereby can change damping oil in A chamber by the open degree of control small ball and be back to the time in oil storage cylinder, also just affect indirectly the speed that valve butterfly plate is closed, play the effect of minimizing, elimination water hammer, this oily control mechanism is mainly realized the pooling feature of valve.
The design's air-control device working principle is as follows:
Opening and closing automatically of a, butterfly plate:
When solenoid valve is during in off-position; butterfly plate is automatically opened under the pressure-acting of medium own; Pneumatic actuator does not play a role; if while there is medium counter flow; butterfly plate can, under the acting in conjunction of counter-flow media pressure, butterfly plate deadweight, automatically be closed, and blocks medium counter flow; avoid blower fan reversing, thereby effectively protect the pipeline equipments such as blower fan.
B, positive closing butterfly plate, its specific operation are as follows:
When solenoid valve is during in "on" position, the clean oil fog body with pressure enters cylinder, and Pneumatic actuator plays a role, and valve butterfly plate can be closed rapidly in 3 ~ 5 seconds.
the beneficial effects of the utility modelby adopting said structure design, on this valve basis that butterfly plate opens and closes automatically under medium effect, there is the function of power-assist pooling feature and positive closing butterfly plate, valve is worn butterfly plate open and close state electric signaling device, opening encapsulation separates, and closes contact and seals, and reduces sealing wear, increase the service life, seal zero leakage simultaneously; Novel and reasonable structure, reliable working performance.
