In figure: 1 valve body, 2 valve plates, 3 cavitys, 4 valve rods, 41 through-holes, 5 opening and closing elements, 51 nuts, 52 screw rods, 53 knobs, 54 are deeply Ditch ball bearing, 6 worm screws, 7 worm gears, 8 handles, 9 grooves.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

In the description of the present invention, it should be understood that term " on ", "lower", "front", "rear", "left", "right", The orientation or positional relationship of the instructions such as "top", "bottom", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.

Referring to figs. 1 to 3, a kind of fixed mechanism for valve, including valve body 1, the top of valve body 1 offer cavity 3, valve The bottom end of body 1 offers water cavity, is equipped with valve plate 2 in water cavity, the middle part of valve plate 2 is fixedly connected with valve rod 4, and valve rod 4 extends to sky In chamber 3 and interference fit has worm gear 7, and worm gear 7 is engaged with worm screw 6, and worm screw 6 is through valve body 1 and interference fit has handle 8, valve rod 4 It is equidistant in circumferential direction to offer at least one through-hole 41.

It is highly preferred that referring to Fig. 2, the quantity of through-hole 41 is six, so that every 60 degree of the rotation of valve rod 4 can be realized admittedly It is fixed.

The top of valve body 1 is equipped with the opening and closing element 5 being used cooperatively with through-hole 41, and opening and closing element 5 includes nut 51, screw rod 52,

Further, referring to Fig. 2, nut 51 is rotatably connected on the top of valve body 1, and screw rod 52 is threadedly coupled with nut 51.
