Description
Technical Field
The utility model relates to a straight stroke actuating mechanism connecting device.
Background
The actuator is a device that controls the drive component of the valve, converts the control signal into a corresponding action to control the position of a closure member in the valve connected to its output shaft or other adjustment mechanism. At present, the output shaft of the straight stroke executing mechanism and the valve rod of the control valve are rigidly connected. Due to the existence of machining errors and assembling errors, coaxiality and straightness deviation inevitably exist between the output shaft of the actuating mechanism and the valve rod. These deviations can lead to the cooperation between valve rod and the direction part not good, increase local resistance, and serious still can cause the valve rod to warp to lead to the complete machine of control valve to creep, the bite scheduling problem, seriously influence control accuracy.
SUMMERY OF THE UTILITY MODEL
In order to overcome the prior art problems, the utility model provides a straight stroke actuating mechanism connecting device.
The technical scheme of the utility model, a straight stroke actuating mechanism connecting device, including actuating mechanism push rod, valve rod, the actuating mechanism push rod passes through screw thread, fixed pin connection spherical bearing, and the split type bearing frame of both sides installation of spherical bearing, split type bearing frame are two lamella formulas, and split type bearing frame passes through the bolt and fixes with split type clamp splice, and the valve rod passes through the screw thread and is connected with split type clamp splice.
The beneficial effects of the utility model are that, this connecting device can be used to various pneumatics, electronic, electric liquid straight stroke actuating mechanism, can bring following profitable effect:
the influence of processing and assembling errors on the effective output of the actuating mechanism is eliminated, and the output efficiency of the actuating mechanism is improved;
the friction resistance caused by radial component force of the actuating mechanism and the pull injury of the push rod which is possibly caused are reduced;
the movement damage of the valve rod caused by the deformation of parts is reduced, and the service life of the whole machine is prolonged;
the split type clamping block is convenient to disassemble and assemble and low in manufacturing cost.
Drawings
FIG. 1 is a side view of the structure of the present invention; FIG. 2 is a top view of the present invention; fig. 3 is an additional view of the split bearing seat.
In the figure: 1. a split type bearing seat; 2. a spherical bearing; 3. a fixing pin; 4. an actuator push rod; 5. a valve stem; 6. a split type clamping block; 7. and (4) bolts.
Detailed Description
As shown in the figure, the straight stroke actuating mechanism connecting device comprises an actuating mechanism push rod 4 and a valve rod 5, wherein the actuating mechanism push rod 4 is connected with a spherical bearing 2 through threads and a fixing pin 3, so that the output force of an actuating mechanism can be transmitted through the spherical bearing 2 and is fixed by the fixing pin 3, the relative motion between the spherical bearing 2 and the actuating mechanism push rod 4 is avoided, and meanwhile, the transmission error caused by thread gaps is eliminated. Split type bearing frame 1 is installed to spherical bearing 2's both sides, and split type bearing frame 1 is two lamella formulas, and split type bearing frame 1 is fixed with split type clamp splice 6 through bolt 7, and valve rod 5 passes through the screw thread to be connected with split type clamp splice 6. The split bearing seat 1 can bear bidirectional load, negative effects of radial component force of eccentric load on the valve rod 5 can be eliminated to the maximum extent, and coaxiality deviation between the push rod 4 of the actuating mechanism and the valve rod 5 is compensated through the gap of the split bearing seat 1.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
