Embodiment 3:
The present embodiment is further optimized based on the above embodiments, further to better implement the present invention,
Especially use following setting structures:
Buried valve opening and closing operator further includes the overload protecting mechanism 7 being set in operator protection sleeve 2, the overload
Protection mechanism 7 is integrally located at 4 top of valve rod assembly or is located at 4 lower section of valve rod assembly, 5 top of planet gear reducing mechanism, this implementation
Example is illustrated so that former arrangement is placed as an example.The overload protecting mechanism 7 is mainly protected by overload protecting mechanism shell 7a, overload
Shield mechanism lower plate 7d and the spring 7b being installed in overload protecting mechanism shell 7a and bead 7c composition.Overload protecting mechanism shell
7a is formed by a top cover and a ring wall by screw fixation, and ring wall offers multiple vertical spring eyes being angularly distributed, mistake
Carry the bottom surface that protection mechanism lower plate 7d is connected to the ring wall of overload protecting mechanism shell 7a, overload protecting mechanism lower plate 7d and overload
Protection mechanism shell 7a can distinguish with respect to rotary motion, such as by overload protecting mechanism lower plate 7d and overload protecting mechanism shell 7a
It is fixed at the Internal and external cycle of bearing, spring eye abuts the top surface overload protecting mechanism lower plate 7d, and spring 7b is placed in the spring eye
Interior, the top of spring 7b abuts the bottom surface of the top cover of overload protecting mechanism shell 7a, and overload protecting mechanism lower plate 7d has quantity
Circular arc bottom groove consistent and one-to-one with spring hole number, circular arc bottom groove are used to align with spring eye, circular arc bottom groove
Groove depth is shallower for accommodating the bottom of bead 7c, and the bottom end of spring 7b, which abuts, has bead 7c towards circular arc bottom
The trend moved in groove makes to rotate in a circumferential direction between spring 7b and bead 7c, axial separation, bead cannot occur
The diameter of 7c is less than the aperture of spring eye.The top surface of the top cover of overload protecting mechanism shell 7a has square shaft, which protrudes into hand
Transmission connection is realized in the square hole of handle 3 therewith, overload protecting mechanism lower plate 7d is connect with the input terminal of valve rod assembly 4.In this way, mistake
It carries protection mechanism 7 to cooperate by vertical spring 7b and bead 7c, after employee's operation handle 3 has arrived extreme position, still
So continuing to rotate handle 3 makes the valve of buried valve body 9 carry out opening and closing operation, at this time just needs to use bigger torsion
Square, when the torque of mechanism operation is greater than safe torque, torque breaks through the limit that spring 7b is born, overload protecting mechanism shell 7a
Overload protecting mechanism lower plate 7d is not rotated when rotation or rotation amplitude is less than overload protecting mechanism shell 7a, and bead 7c is by groove
Effect jacked up, the spring 7b of overload protecting mechanism 7 can be compressed with bead 7c, until bead 7c is detached from original circular arc
After the groove of bottom, overload protecting mechanism shell 7a and overload protecting mechanism lower plate 7d carry out tick over, under overload protecting mechanism
The not raw rotation of plate 7d, ensure that the safety operation of equipment, is finally reached the protective effect to integral device.
Preferably, overload protecting mechanism shell 7a and overload protecting mechanism lower plate 7d can be used following mechanism and realize that revolution connects
Connect: the inner wall bottom end of the ring wall of overload protecting mechanism shell 7a has an interior annular, which forms necking, overload protection machine
Protruded at the top of structure lower plate 7d on the inside of overload protecting mechanism shell 7a, the top side detachable of overload protecting mechanism lower plate 7d it is fixed
There is a gland 7e, a bearing is provided between gland 7e and the ring wall of overload protecting mechanism shell 7a, 7e, gland in the bearing
Outer ring at, which makes gland 7e be pressed on interior annular indirectly in the top surface of the ring wall of overload protecting mechanism shell 7a
Top surface；The activity performance for not considering overload protecting mechanism shell 7a Yu overload protecting mechanism lower plate 7d, can also cancel bearing
Setting, gland 7e is directly pressed on to the top surface of interior annular.
Embodiment 4:
The present embodiment is further optimized based on the above embodiments, further to better implement the present invention,
Especially use following setting structures:
Due to valve opening to the process closed always within the scope of 90 °, however since space is limited, and be mounted with
After a set of planet gear reducing mechanism 5, operator top has a biggish revolving speed and amplitude including handle 3.It can not be with
Valve-opening position is corresponded to, therefore according to this situation, it needs to design a set of indicating mechanism here, to reach very big deceleration
Effect, and operator is finally made to complete the instruction operation within the scope of 90 °.
