Embodiment
Accompanying drawing is embodiment of the present utility model.
Below in conjunction with accompanying drawing summary of the invention of the present utility model is described further:
With reference to Fig. 1, Fig. 2, shown in Figure 3, comprise by valve gap 1, dome 2, gas-flow closure circle 3, sealed liner 4, sealed support 5, valve body 6, rotating shaft 7, pneumatic actuator 8, drive sleeve 9, adjusting screw 10, mechanical commutation valve 11, signal feedback device 12 and solenoid directional control valve A constitute, described dome 2 is installed in the rotating shaft 7 that is connected with pneumatic actuator 8, rotating shaft 7 is connected with drive sleeve 9, and the gas-flow closure circle 3 inflation backs that are embedded on the sealed liner 4 are fitted and connected with dome 2 spheres, are connected with sealed support 5 on the valve body 6, sealed support 5 is connected with sealed liner 4, described selector valve 10 is by adjusting screw 10 touch switchs that are installed on the connecting body, and described signal feedback device 11 is provided with power supply, and the two ends of its power supply are parallel with relay K successively, K switch 1, K switch 2, K switch 3, solenoid directional control valve A, be connected in series with pressure controller B and alarm W on the K switch 1, K switch 2, connect tutorial light X1 on the K switch 3, X2.The expansion of the keying of said dome 2 and gas-flow closure circle 3 is dwindled and is carried out synchronously.Pressure controller is connected with circuit and sends warning in the said signal feedback device 11.Reveal impaired the breaking of seal element, when choked flow is incomplete, in time send alarm signal, be convenient to staff's on-call maintenance and change damaged element.
Working principle:
During valve closing, relay electric-loss, solenoid directional control valve A is air inlet road, conducting pneumatic actuator 8 right ventricles and left chamber exhaust line under the effect of spring, pressure gas source is introduced in pneumatic actuator 8 right ventricles, drive pneumatic actuator 8 and drive be connected drive sleeve 9 and rotating shaft 7, rotating shaft 7 drives dome 2 rotations, when dome 2 during near the position, depress the mechanical commutation switch contact with the stop screw 10 on the drive sleeve 9 that rotating shaft 7 is connected, conducting seal ring air inlet road, make pressure gas source enter inflation in the gas-flow closure circle 3, realized that dome 2 revolves to turn 90 degrees and put in place and gas-flow closure circle 3 inflations, fit tightly two actions with dome 2 spheres and finish synchronously, valve is closed fully, material stops to flow;
During valve open, solenoid directional control valve A energising, conducting air inlet road, chamber, a left side and right ventricle's exhaust line, it is indoor that pressure gas source enters pneumatic actuator 8 left sides, valve is opened in rotating shaft 7 that driving is connected and dome 2 counterrotatings, and stop screw 10 breaks away from mechanical reverser release contact simultaneously, and conducting seal ring exhaust line is shunk the seal ring exhaust, valve is opened fully, the logistics conducting.Realized valve dome 2 close rotate in place and when opening and 3 inlet and outlet of gas-flow closure circle finish simultaneously, with quick opening and closing valve, exempted grey gas material to acutely washing away in the seal element opening-closing process.Synchronous realization obtains by regulating selector valve adjusting screw 10.
When its pressure was reduced to setting pressure when signal feedback device 12 began to take place to reveal in 3 damages of gas-flow closure circle; the pressure controller B conducting alarm buzzer W signal that gives the alarm reminds the staff in time to overhaul the repair and replacement damaged element; to protect other devices not suffer a loss, reduce maintenance expenses.
The effect of each element in the signal feedback device 12: relay K is the control switch of valve, be connected with the solenoid directional control valve A of pressure controller B-source K switch 1 (long closing), valve closing indicator light switch K2 (long closing), valve open indicator light switch K3 (long opening), control pneumatic actuator 8, be connected in series with pressure control device B and alarm W on the K switch 1, connect tutorial light X1, X2 on K switch 2, the K switch 3.
The course of action of signal feedback device 11: when valve closing, the relay K dead electricity, its K1 closure, pressure controller B energising, but when seal ring 3 internal air pressures when setting value is above, connect the contact disconnection of the pressure controller B of alarm, alarm W does not report to the police; When the air pressure in the seal ring 3 when setting value is following, connect the make contact of the pressure controller B of alarm W, alarm W powers alarm.When valve open, the relay K adhesive, its K1 disconnects, pressure controller B and alarm W outage, though the decline of seal ring 3 exhaust pressure, because of alarm W can not report to the police yet.Valve closing indicator light switch K2 is when valve closing, and tutorial light is bright, otherwise lamp goes out; Valve open indicator light switch K3 is when valve open, and tutorial light is bright, otherwise lamp goes out.
