Abstract
The utility model discloses a butterfly valve opening and closing device, which is characterized by comprising a worm gear mechanism and a bevel gear transmission mechanism (4) formed by a pair of bevel gears. A worm gear (1) of the worm gear mechanism is connected onto a butterfly valve rod, one bevel gear of the bear gear transmission mechanism (4) is fixedly connected onto the end portion of a worm (3), another bevel gear is fixedly connected onto an output shaft (5), and the output shaft (5) is movably connected onto the support point. The butterfly valve opening and closing device adopts the worm gear mechanism and the bevel gear transmission mechanism to achieve opening and closing together, improves opening and closing efficiency and greatly improves opening and closing speed due to the fact that the bevel gear transmission mechanism is adopted.
Description
Technical field
The utility model relates to the start-stop device of butterfly valve.
Background technique
Butterfly valve is widely used in the industrial and agricultural production.The keying of macrotype butterfly valve is provided in a side of start-stop device realization keying special-purpose on the butterfly valve.At present, the start-stop device of macrotype butterfly valve commonly used is realized through the double worm and gear mechanism driving.Because the worm and gear transmission efficiency is low, it is low therefore to open and close efficient, has the slow-footed problem that opens and closes simultaneously.
The model utility content
The purpose of the utility model solves the macrotype butterfly valve start-stop device exactly and adopts the double worm and gear transmission, exists keying efficient low, opens and closes slow-footed problem.
The technological scheme that the utility model adopts is: a kind of butterfly valve start-stop device; It is characterized in that it comprises the bevel gear drive mechanism that worm-and-wheel gear and bevel-gear sett constitute; The worm gear of described worm-and-wheel gear is connected on the butterfly valve valve rod; A bevel gear of described bevel gear drive mechanism is fixed in the end of worm screw, and another bevel gear is fixed on the output shaft, and output shaft is actively connected on the fulcrum.
The bevel gear diameter that is fixed in the worm screw end of described bevel gear drive mechanism is greater than the diameter that is fixed in the bevel gear on the output shaft.
Described worm-and-wheel gear and bevel gear drive mechanism are positioned at housing.
The beneficial effect of the utility model is: because the utility model adopts worm-and-wheel gear and bevel gear drive mechanism to realize jointly opening and closing, improve keying efficient, owing to adopt bevel gear drive mechanism, keying speed improves greatly.
