The outer edge surface of second sleeve 5 is equipped with the first groove 6 cooperated with pin 4, and the inside of second sleeve 5, which is equipped with, rotatably to be connected
Bar 7, the lower end of connecting rod 7 are equipped with the counterbore matched with valve rod 2, and the upper surface center of connecting rod 7 is fitted with top moving up and down
Bar 8, the rotation of mandril 8 can drive connecting rod 7 to rotate；Through the driving lever 9 for having left and right to place on mandril 8, driving lever 9 can be along mandril 8 or so
It is mobile, the second groove 12 for placing driving lever 9 is offered on the upper surface of connecting rod 7.
Embodiment two, on the basis of example 1, for the ease of using, the first sleeve 3, second sleeve 5, top
Bar 8, valve rod 2 axis be overlapped.
Embodiment three, on the basis of example 1, in order to enable 4 the first groove of clamping 6 of pin, the pin 4
Outer end is equipped with protrusion, is set with tension spring 10 on pin 4, one end of tension spring 10 is fixed in protrusion, and the other end of tension spring 10 is fixed
On 3 outer edge surface of first sleeve；The inner end of pin 4 is equipped with the inclined-plane of inclination upward.
Example IV, on the basis of example 1, in order to place 4 rotation of pin, the cross section of the pin 4 is side
Shape.
Embodiment five is equipped with multiple bearings between the connecting rod 7 and second sleeve 5 on the basis of example 1.
Embodiment six is fallen on the basis of example 1 in order to place dust, is equipped in the second sleeve 5
The lid 11 that can be swung, lid 11 it is wherein hinged between the upper surface of second sleeve 5 on one side.
Embodiment seven, on the basis of example 1, in order to make the rotation of mandril 8 that connecting rod 7 can be driven to rotate, the mandril
8 cross section is rectangular.
Embodiment eight, on the basis of example 1, the length of the driving lever 9 are less than the interior straight warp of second sleeve 5.
The use state of the utility model is, before use, valve body 1, valve rod 2 and first sleeve 3 are one, second sleeve
5, connecting rod 7 and the part being mounted in second sleeve 5 are integrated；When installation, valve body 1 is mounted on pipeline first
On, after being installed, second sleeve 5 is inserted into the inside of first sleeve 3, pin 4 can be stuck in 5 outer edge surface of second sleeve at this time
Groove in, make second sleeve 5 not and can be carried out rotation and move up and down.
Since the inner edge surface of connecting rod 7 and second sleeve 5 inside second sleeve 5 makes to be attached by bearing, the
It can not generate and move up and down between two sleeves 5 and connecting rod 7, therefore after second sleeve 5 is fixed, valve rod 2 can be inserted at this time
Into the counterbore of the lower end of connecting rod 7, rotating the rotation energy band ovable valve stem 2 of connecting rod 7 together, (cross section of valve rod 2 and counterbore is equal
