Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valves, in particular to a clamp-type high-performance heating butterfly valve. Background Art

[0002] Wafer butterfly valve is a commonly used valve type, mainly used to control the flow of media in pipelines. Wafer butterfly valve uses two bolts to clamp the valve between the two flanges of the pipeline, without the need for welding or drilling on the pipeline. It has the advantages of simple structure, small size, light weight, and easy installation. Wafer butterfly valve is widely used in industrial fields such as petroleum, chemical industry, electric power, metallurgy, papermaking, and water treatment.

[0003] However, the existing wafer-type butterfly valve has a single adjustment method. The manual adjustment method of rotating the dial is time-consuming and labor-intensive, and the operation intensity is high. The reduction motor driven adjustment method can save physical strength and improve efficiency. Since the reduction motor is a wearing part, when the reduction motor is damaged, the valve cannot be used, thereby reducing the performance of the equipment. For this reason, a wafer-type high-performance heating butterfly valve is proposed. Utility Model Content

A first gear is fixedly provided on the worm, and a second gear is fixedly provided at the output end of the reduction motor. The first gear and the second gear are engaged for transmission, and an adjusting wheel is inserted into one end of the worm.

[0017] 1. Compared with the existing technology, this pair of high-performance clamp-type heating butterfly valve can adjust the butterfly valve in two ways by setting a reduction motor, an adjusting wheel, a turbine, a worm, a first gear and a second gear. The worm is driven by the reduction motor to save the physical strength of relevant personnel.

[0018] 2. Compared with the existing technology, this pair of high-performance heating butterfly valves with clamping type is equipped with a storage box, a pull rod, a clamping plate and a spring. After the valve is adjusted by using the adjusting wheel, the adjusting wheel can be pulled outward to separate it from the worm, which can reduce the probability of the valve plate opening and closing degree changing due to the adjusting wheel being accidentally touched. Then the two pull rods are pulled away from each other, and the pull rods drive the clamping plate, and then the spline is extended through the through hole on the top inner wall of the storage box into the storage box. Then the pull rod is released, and the two clamping plates are pushed close to each other by the spring to clamp the spline, thereby realizing the storage of the adjusting wheel and reducing the space occupied by the adjusting wheel.
