Background technique
Common double-acting actuating mechanism is air-cylinder type, and structure is complicated, and weight is big, and cost is high.Common air bladder formula is held
Row mechanism is generally divided into two kinds i.e. Single spring and multiple springs combined type, single-acting executing agency because counter spring force there are power outputs
It will be greatly reduced, and single-acting executing agency increases weight and cost because spring exists.
Executing agency's push rod and the common screw thread that is connected as of valve rod are direct-connected, connect reliable but do not have anti-rotating function, adjust
Save push rod and valve lever clearance be very troublesome, the connector of existing band guiding is generally clamping plate sliding friction formula, due to manufacture and
Installation error, resistance is very big during exercise for the two pieces matched, will lead to movement clamping stagnation when serious, if executing agency's thrust
The larger deformation that also will cause valve rod.
The connection of actuator bracket and valve bonnet, is usually the distribution connection of bolt and nut even circumferential, because of connecting hole
Limitation, executing agency and regulating mechanism installation angle fix, when use site space limit or be conducive to operation tune
Turn to cannot achieve when mode.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of pneumatic single diaphragm type double-acting actuating mechanism, volumes
Distance is adjustable between small, High power output, push rod and valve rod, convenient for disassembly and assembly.
To achieve the above object, the utility model is implemented with the following technical solutions:
A kind of pneumatic single diaphragm type double-acting actuating mechanism, including upper membrane cover, diaphragm, lower membrane cover, bracket, push rod, stroke
Diaphragm and push rod are equipped in direction board, upper membrane cover and lower membrane cover, push rod passes through slit nut component and straight travel regulating valve valve rod
Connection, the side inner wall of bracket are equipped with the guide pad of protrusion, slit nut component and guide pad sliding contact, slit nut group
Part includes seperated fixture block, guide wheel, and seperated fixture block is connected by clamping bar screws, is equipped with and cracks among two fixture blocks after combination,
One end of cracking is equipped with the groove that matches with guide pad, is respectively equipped with guide wheel on the fixture block of groove two sides, guide wheel is along rack inner wall
Two side roll of guide pad, fixture block after combination is respectively equipped with the screw thread to match with push rod and straight travel regulating valve valve rod up and down
Hole, upper and lower threaded hole centre are equipped with cavity, and a fixture block outer surface connects indicateing arm.
The rack inner wall of the slit nut component opposite side is equipped with stroke direction board.
The side of the upper membrane cover and lower membrane cover is respectively equipped with the first gas source interface and the second gas source interface.
The bracket is mounted on bonnet, by round nut.
Compared with prior art, the beneficial effects of the utility model are:
1. double-acting actuating mechanism uses single diaphragm type, cost is reduced, reduces volume.
2. because of the counter-force without single-acting formula spring, power output is bigger.
3. slit nut is separate structure, adjustment the distance between push rod and valve rod can be facilitated, and convenient for disassembly and assembly.
4. slit nut band anti-rotation structure, the rotation that push rod, valve rod can be effectively prevent to generate under out-of-balance force effect, prevent
There is guide wheel guide frame in transfer part position, reduces frictional resistance, not clamping stagnation.
5. bracket is connect with bonnet, using round nut, can make to install at an arbitrary position between two pieces.
