Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail: as shown in Figure 1 to Figure 3, heavy caliber PE ball valve booster, comprise scaffold 1, the valve rod worm gear 4 of actuate valve stem rotation and the active worm screw 2 being connected outside force is provided with in described scaffold 1, described valve rod worm gear 4 is by the driven worm screw 32 that has been connected with a joggle, described driven worm screw 32 is arranged on dwang 3, described dwang 3 is provided with transmission worm gear 31, and described transmission worm gear 31 has been connected with a joggle described active worm screw 2.
Described valve rod worm gear 4 arranged wheel teeth portion 41 and take turns teeth portion 41 and to be meshed with described driven worm screw 32 by this and to be connected, to be central angles be in described cross section of taking turns teeth portion 41 100 ° fan-shaped.
Described scaffold 1 is positioned at valve rod worm gear 4 both sides and is provided with first Limit screw 5 and second Limit screw 6, described first Limit screw 5 and the adjustable length stretched in described scaffold 1 of described second Limit screw 6.
The number of teeth of described valve rod worm gear 4 is 23.
Described driven worm screw 32 is single head.
The valve rod worm gear 4 of this device is connected with the valve rod of ball valve, after valve rod worm gear 4 rotates, ovable valve stem just can be with to rotate, thus realize the opening and closing of ball valve.
During this device busy, first rotate initiatively worm screw 2 by outside force, then because the relation of engagement, initiatively worm screw 2 drives transmission worm gear 31 to rotate.Because transmission worm gear 31 and driven worm screw 32 are all positioned on dwang 3, so after transmission worm gear 31 rotation, driven worm screw 32 will be made also to rotate, and both angular velocity is identical.After driven worm screw 32 is rotated, then because the relation of engagement, just can order about valve rod worm gear 4 and rotate.Finally, valve rod worm gear 4 orders about valve rod and rotates, thus realizes the opening and closing of ball valve.
