In order to solve the problems of the technologies described above; The technological scheme that is adopted is: the self-locking manually operated valve, comprise positioning seat, control lever, movement registration arm, precompressed locking spring, locking button and valve body, and positioning seat is installed in the control end of valve body; Positioning seat top is provided with first active face and second active face that links together; Have first positioning hole on first active face, have second positioning hole on second active face, first positioning hole and second positioning hole are communicated with through guiding groove;
One end of control lever is positioned at positioning seat inside and is connected with valve body; The other end of control lever is equipped with the locking button from top and the end that first positioning hole, second positioning hole and guiding groove reach positioning seat through screw thread; Control lever is positioned at the outer end of positioning seat and is set with movement registration arm; Movement registration arm has near an end inside of locking button the precompressed locking spring that is sleeved on the control lever is installed in groove and the groove, and movement registration arm is provided with positioning end near an end of positioning seat.
Described guiding groove is an elongate slots, or is r shape groove, or is curve bath.
The cross section of described positioning end is circular, or is square, or is trapezoidal, or is triangle, or is oval.
The width of described guiding groove is less than the width of positioning end, and described first positioning hole and the second positioning hole diameter are greater than the width of positioning end.
Described positioning seat is a case structure.
The utility model compared with prior art has following beneficial effect.
1, the precompressed locking spring between the utility model movement registration arm and the control lever makes the movement registration arm can be up and down; Control lever can be movable between two positioning holes on the positioning seat and guiding groove when movement registration arm was mentioned; The positioning end of movement registration arm lower end descends when operation puts in place and is fixed in the corresponding positioning hole; The location is reliable, and is simple to operate.
2, the utility model is equipped with the locking button in the control lever end through screw thread, when needing extended immobilization control lever position, screws the locking button, realizes single station self-locking, and avoiding the people is misoperation.
3, the positioning seat of the utility model adopts case structure, has strengthened non-deformability.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is done further to specify.
Fig. 1 is the structural representation of the utility model self-locking manually operated valve.
Fig. 2 is the left view of Fig. 1.
