Abstract
The utility model discloses a diaphragm-type pneumatic driver, wherein the driver is arranged on a valve cover (1) and comprises a spring (2), a lower cover (3), a spring pressed cover (4), a diaphragm (5) and an upper cover (6). A driving cavity is formed by connecting the lower cover (3) and the upper cover (6). The diaphragm (5) is arranged inside the driving cavity between the lower cover (3) and the upper cover (6), and divides the driving cavity into an A cavity (8) with pressure and a B cavity (9) free of pressure, wherein the spring (2) is arranged inside the B cavity (9) and the location of the spring (2) is limited by the spring pressed cover (4). The upper cover (6) is provided with two connectors, and one is used for connecting a pressure supply and the other is used for assembling an overload protector. The upper cover (6) is also provided with an indicating rod. The driving cavity of the diaphragm-type pneumatic driver is divided into the A cavity with pressure and the B cavity free of pressure, so that when the valve is opened or closed, the diaphragm can provide an opening force through transformation, and the whole diaphragm can be an effective pressure-bearing area for the pressure supply. Accordingly, the driving force is enhanced, requirement for the pressure supply is reduced, the service life of the driver is prolonged, and the interval time of maintenance is prolonged.
Description
Technical field
The utility model relates to a kind of valve pneumatic actuating device, and this device can be operated the switch of valve, and Pneumatic actuator is the diaphragm of rubber formula.
Background technique
Present known valve operating mechanism mostly is manually operated type, hydraulic piston controlling type, pneumaticpiston controlling type etc., type hand is unfavorable for long-range and automation control, hydraulic piston and air pressure piston type wear and tear aspect Sealing comparatively fast, need periodic maintenance, change Sealing, need higher operation pressure in operating aspect, pressure source is had relatively high expectations.
Summary of the invention
The purpose of this utility model is: a kind of diaphragm type pneumatic driver is provided, reduces the requirement to pressure source, solve manually, surge and other Pneumatic actuator is had relatively high expectations to pressure source and problem difficult in maintenance.
Technical solution of the present utility model is: driver is installed on the valve gap; this driver comprises spring, lower cover, spring capping, barrier film and loam cake; lower cover connects loam cake and forms actuator chamber; barrier film is installed between lower cover and loam cake in actuator chamber actuator chamber is divided into A with pressure chamber and B not with pressure chamber; mounting spring in the B chamber; spring is spacing by spring capping; on covered two interfaces; one is used to connect pressure source; another is used for the setting pressure overload protective device, on cover the installation indicating arm.
During installation, one of them interface of loam cake connects pressure source, another interface setting pressure overload protective device, and the A chamber forms the chamber that seals by barrier film, can seal certain gas pressure; During work, pressure enters the A chamber, diaphragm deflection, driving the spring capping pressure spring moves downward to the valve opening position, if this moment, pressure did not shed then driver is shown in an open position always, when shedding pressure, spring promotes barrier film and moves up to the valve closing position, has finished whole switch motion by such mode.
The utlity model has following advantage: 1, barrier film is divided into A with pressure chamber and B not with pressure chamber with whole actuator chamber, in the opening-closing process of valve, barrier film provides breaking force by distortion, whole barrier film all is effective lifting surface area of pressure source, increased the lifting surface area of pressure source greatly, increased driving force, reduced requirement pressure source; 2, barrier film is by self elastic working, and the barrier film place does not have physical friction, has reduced wearing and tearing, has improved the life-span of driver, has increased the service intervals time, has reduced maintenance cost; 3 adopt the mode of pneumatic drive to work, and spring is used to driver that restoring force is provided; 4, indicating arm plays stable and indicative function, has improved sealing stability.
Description of drawings
Fig. 1 is a diaphragm type pneumatic activation configuration schematic representation.
Among the figure: 1 valve gap, 2 springs, 3 lower covers, 4 spring cappings, 5 barrier films, 6 loam cakes, 7 indicating arms, 8 A chambeies, 9 B chambeies.
Embodiment
As shown in Figure 1; driver is installed on the valve gap 1; this driver comprises spring 2, lower cover 3, spring capping 4, barrier film 5 and loam cake 6; lower cover 3 connects loam cake 6 and forms actuator chamber; barrier film 5 is installed between lower cover 3 and loam cake 6 in actuator chamber actuator chamber is divided into A with pressure chamber 8 and B not with pressure chamber 9; mounting spring 2 in B chamber 9; spring 2 is spacing by spring capping 4; two interfaces are arranged on the loam cake 6; one is used to connect pressure source; another is used for the setting pressure overload protective device, and indicating arm 7 is installed on the loam cake 6.
During installation, one of them interface of loam cake 6 connects pressure source, another interface setting pressure overload protective device, and A chamber 8 forms the chamber that seals by barrier film 5, can seal certain gas pressure; During work, pressure enters A chamber 8, barrier film 5 distortion, driving spring capping 4 pressure springs 2 moves downward to the valve opening position, if this moment, pressure did not shed then driver is shown in an open position always, when shedding pressure, spring 2 promotes barrier film 5 and moves up to the valve closing position, has finished whole switch motion by such mode.
