Section.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of embodiment of turbine butterfly valve of the invention；
Fig. 2 is the main view of Fig. 1.
Specific embodiment
The embodiment of turbine butterfly valve of the invention：As shown in Figure 1 and Figure 2, including valve seat 1, axis edge is installed in valve seat 1
Valve seat 1 is stretched out in the front end of the worm screw 5 that front-rear direction extends, worm screw 5, and worm screw positioning and locking device is equipped on extension.
Worm screw positioning and locking device includes the axle sleeve 8 being set on worm screw 5, has been wholely set locking wheel disc 6 on the outer peripheral surface of axle sleeve 8,
Spring catch 7 is radially inserted between axle sleeve 8 and worm screw 5, and the positioning of axle sleeve 8 and locking wheel disc 6 may be implemented in this way.Locking wheel disc
Locking arm is installed on 6, locking arm is made of locking ontology 3 and latch 2, and locking ontology 3 is to be installed on locking wheel disc top
The U-shaped structure of position is screwed into there are two lock-screw 4 on the cell wall of front side, can will lock ontology 3 by lock-screw 4
Rear side cell wall is pressed in the rear disk of locking wheel disc 5, realizes that the removable of locking arm and locking wheel disc 6 is connected, by it is this can
Radial position of the locking arm on locking wheel disc 5 can also be adjusted by tearing fixed structure open, that is, realize moving radially for locking arm；Latch
2 are vertically installed on the rear side cell wall of locking ontology 3, by adjusting the upper and lower radial position of locking arm, when the plate of latch
Two lock-screws 4 are tightened when compressing in face and the upper surface of valve seat, can be realized by latch 2 and the block cooperation of valve seat 1
The rotation stop of locking wheel disc 6, and then realize the rotation stop of worm screw 5, the disk body of locking wheel disc 6 is the connection realizing locking arm and being fixedly connected
Arm.In the present embodiment, due to realizing the fixation of locking arm and locking wheel disc 6 by lock-screw 4, in order to ensure fixed effect,
Locking wheel disc 5 be friction wheel disc, i.e., the disk of locking wheel disc 6 be can the high rubbing surface of coefficient of friction, locking can be increased in this way
Ontology 3 and locking wheel disc 6 mutually compress the frictional force between two mating surfaces of cooperation.
As advanced optimizing, due to the frictional force between locking ontology 3 and locking wheel disc 6 also with the contact area of the two
Related, moving up for locking arm and the contact area that both causes are reduced or are reduced and is excessive in order to prevent, lock the rear side slot of ontology 3
Wall extends downward into the lower edge of locking wheel disc 6, while the rear side cell wall for locking ontology 3 has the escape groove for avoiding worm screw 5.
Above-described embodiment specific operation process is as follows：First locking mounting base is set on worm screw 5, insertion spring catch 7 will
Axle sleeve 8 and worm screw 5 fasten, and then rotary worm 5 makes turbine butterfly valve be adjusted to predetermined angular, and locking arm is installed on locking later
On wheel disc 6, and guarantee that the upper surface of latch 2 and valve seat 1 compresses, finally tightens two lock-screws 4, worm screw 5 can be completed
Positioning and locking.
In above-described embodiment, due to any one position using locking wheel disc as linking arm, on locking wheel disc circumference
It can all realize the installation of locking arm, axle sleeve and worm screw can be adjusted to the predetermined angular of turbine butterfly valve in this way, at other after fixed
In embodiment, linking arm can also be installed in one end of linking arm, be needed using the strip structure radially extended along worm screw, axle sleeve
It is noted that when in use, axle sleeve and worm screw could be fixed after turbine butterfly valve is adjusted to predetermined angular, to guarantee to connect
The other end of arm upward, just will not influence the compression fit of latch and valve seat in this way.
In other embodiments, if linking arm uses the structure of locking wheel disc, axle sleeve and worm screw can also be using key connections.
In other embodiments, locking arm can also be slidedly assemblied in the sliding block in locking wheel disc disk using radially-directed
Structure, and sliding block positioning is realized by lock-screw, also needing could be by axle sleeve after turbine butterfly valve is adjusted to predetermined angular
It is fastened with worm screw.
In above-described embodiment, the disk of locking wheel disc is rubbing surface, in other embodiments, cell wall on rear side of locking ontology
Inner wall may be rubbing surface, also can guarantee the frictional force of the two, locks two mating surfaces of ontology and locking wheel disc certainly
It can be rubbing surface.
The embodiment of the worm screw positioning and locking device of turbine butterfly valve of the invention：As shown in Figure 1 and Figure 2, with above-described embodiment
In worm screw positioning and locking device structure it is consistent, details are not described herein for content.
