Abstract
The utility model discloses a gate valve, which comprises a valve body, a movable valve plate in the valve body and four groups of switch devices arranged symmetrically on four corners of the valve body those are driven by power source through a transverse transmission shaft, two longitudinal transmission shafts. The switch devices are a worm gear composed of a worm and a worm wheel that is arranged on a longitudinal transmission shaft end and a nut arranged vertically on the valve body and that is driven by the worm wheel. The T-shaped active valve seat and fixed valve seat are arranged on two sides of the movable valve plate in the valve body. The T-shaped active valve seat is connected to the end of a lead screw extended out of the valve body. Such lead screw matches with the nut arranged on the valve body. In comparison with multilevel bevel gear driving, the driving method of such switch has the advantages of larger transmission ratio, large moment and stable driving etc. Meanwhile, the entire structure of the gate valve is more tight and the action more sensitive without blocking.
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of push-pull valve.
Background technique
Push-pull valve is widely used on the heavy caliber gas pipe line, makes switching element and uses.At present the switching mechanism of the removable valve plate of control push-pull valve is general adopts multistage bevel gear drive, because that the diameter of pipeline, opens and closes moment generally at 1-3 rice is bigger, causes existing switching mechanism complexity, bulky, is prone to the action card phenomenon of waiting indefinitely during keying.
The model utility content
The purpose of this utility model is active in one's movements when being a kind of the keying is provided, the push-pull valve of compact structure.
For achieving the above object, the utility model can be taked following technical proposals:
Push-pull valve described in the utility model, it comprises valve body, is movably arranged on the removable valve plate in the valve body, and be symmetricly set on four groups of switch gears on four jiaos of the valve bodies by what cross moving axis, two longitudinal drive shafts drove by power source, it is characterized in that: described switch gear is to be arranged on the worm gear pairs of being made up of worm screw, worm gear of longitudinal drive shaft end and by the screw on the valve body of being vertically set on of described worm gear drives; The both sides of removable valve plate are provided with movable valve seat of shape and fixed valve base in valve body, and the end of the leading screw that the movable valve seat of described shape is outer with extending valve body is connected mutually, and this leading screw is complementary with the described screw that is arranged on the valve body.
Advantage of the present utility model is that switch gear is to be arranged on the worm gear pairs of being made up of worm screw, worm gear of longitudinal drive shaft end and by the screw on the valve body of being vertically set on of described worm gear drives; The both sides of removable valve plate are provided with movable valve seat of shape and fixed valve base in valve body, and the end of the leading screw that the movable valve seat of described shape is outer with extending valve body is connected mutually, and this leading screw is complementary with the described screw that is arranged on the valve body.When pipeline need be opened or closure, when promptly needing mobile valve plate, power source just changes, cross moving axis, longitudinal drive shaft rotate successively, driving the quadruplet worm gear pairs be arranged on four jiaos of the valve bodies simultaneously rotates, worm gear and screw rotate simultaneously leading screw drive activity valve seat are moved backward, and sealing surface breaks away from, and valve plate moves into place as requested; And then make power source counter-rotating, and horizontal, longitudinal drive shaft rotates, and the quadruplet worm gear pairs that is arranged on four jiaos of the valve bodies rotates simultaneously, and worm gear and screw rotate simultaneously leading screw drive activity valve seat are moved forward, and sealing surface clamps, and finishes once and moves.The kind of drive of this kind switch compare with multistage bevel gear drive have that velocity ratio is big, moment is big and advantage such as stable drive, makes the overall structure of plate valve compact more simultaneously, action is sensitive more, stuck phenomenon can not occur.
