Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as Figure 1 to Figure 6 As shown, a pneumatic amplifier that can realize the function of three-break position retention includes an air source port 4, a constant pressure chamber 6, a first amplifier 2, a second amplifier 3, a third amplifier 9, a fourth amplifier 8, and a nozzle 10. And a nozzle outlet pressure control device 11 close to the nozzle 10.

[0029] The nozzle outlet air pressure control device 11 includes a baffle near the nozzle 10 and a coil assembly for driving the baffle to move. Wherein, after the coil assembly is energized, the baffle can be controlled to approach or move away from the nozzle 10 .

[0030] The first amplifier 2, the second amplifier 3, the third amplifier 9 and the fourth amplifier 8 are all provided with a pilot air chamber 12 and an amplifying chamber 13, and the first amplifier 2 ...

Abstract

The invention discloses a pneumatic amplifier capable of achieving the three-outage position protecting function. The pneumatic amplifier comprises a gas source port, a constant-pressure cavity, a first amplifier, a second amplifier, a third amplifier, a fourth amplifier, a nozzle and a nozzle gas outlet pressure control device close to the nozzle. Through adjustment on the distance between the nozzle gas outlet pressure control device and the nozzle, the on-off states of a passage between a gas outlet, a gas inlet and an exhaust port can be controlled, and the three-outage position protectingfunction is achieved. The structure is simple, the three-outage position protecting function can be achieved without additionally arranging a power-loss comparator or an electromagnetic valve or an air lock valve or other components, cost is reduced, and installation is simplified.

Description

technical field [0001] The invention belongs to the technical field of pneumatic amplifiers, in particular to a pneumatic amplifier capable of realizing the function of three-break position protection. Background technique [0002] At present, the pneumatic amplifier for intelligent valve positioner cannot realize the three-break position protection function of power failure, signal failure and gas failure. When there is a need on site, only a power failure comparator, solenoid valve and air lock valve can be added to assist in completing this function. [0003] In the existing technology, when the gas or power of the instrument is cut off, the gas outlet and the exhaust port are connected to empty the gas in the actuator, and the actuator will return to the initial position. Additional accessories are added to realize the three-break position, which increases the complexity of the system. and user costs. Contents of the invention [0004] In order to solve the problem th...
