Upper end forms the effect of lock.
Preferably, described interior magnetic shoe ring set 8 and outer magnetic shoe ring set 9 are permanent magnetism magnetic cylinder, described handwheel 1
And pivot bush unit between described isolating cylinder 2.
The operation principle of this gate valve is: when valve needs to open and close, first handwheel 1 is sleeved on isolating cylinder
On 2, then rotating handwheel 1, inner magnetic core 7 concomitant rotation, owing to inner magnetic core 7 is rigidly fixed in support magnetic
On yoke 3, supporting yoke 3 internal is to threaded with valve rod 4, and such valve rod 4 will move up and down.
Due to the friction between screw thread and the pressure of medium, support yoke 3 and can do or the moving axially and week of up or down
To rock.Axial mobile meeting is limited by axial alignment system, and rocking by circumference of circumference is fixed
The constraint of ball bearing 16 in the system of position, supports yoke 3 and would be at a stable duty, valve
The keying operation of door will be brisk, flexibly.After keying operation completes, handwheel 1 can take off and take away, so
Both can prevent maloperation from bringing harm, artificial destruction can have been prevented again.
The above is only the preferred embodiment of the present invention, it is noted that general for the art
For logical technical staff, under the premise without departing from the principles of the invention, it is also possible to make some improvement and profit
Decorations, these improvements and modifications also should be regarded as protection scope of the present invention.
