Abstract
The invention relates to a gate valve. The gate valve comprises a valve seat body (1), wherein a gate plate (6) driven by a power device (2) is arranged in the valve seat body. The gate valve is characterized in that supporting plates (5) are arranged at the symmetrical positions on the two sides of the valve seat body respectively, racks (5a) are arranged on the supporting plates, a transmission shaft (3) is arranged on one side of the gate plate, the two ends of the transmission shaft are respectively provided with a gear (3a), the gears (3a) are matched and meshed with the racks (5a), and the transmission shaft is connected with the gate plate in a matched mode through a bearing seat (4). The gate valve has the advantages that the structure is simple, the reliability is high, S-shaped twisting is prevented from being generated when the gate valve is opened or closed, force for opening and closing the valve is stable, and the maintenance rate is lowered.
Description
Technical field
The present invention relates to pipeline valve field, particularly a kind of push-pull valve.
Background technique
At present, push-pull valve is widely used in the pipeline fluid transporting system of chemical industry, machine building industry and all trades and professions, has the good characteristics such as flow resistance is little, compact structure, full-bore circulation.And existing push-pull valve, in the time of the operation that opens and closes flashboard, the flashboard being connected with valve body there will be snakelike swing in various degree, so that flashboard is stuck, and this has not only increased the weight of machine shop worker's labor intensity, has also affected manufacturing schedule.
Summary of the invention
While the object of the invention is to solve the push-pull valve keying flashboard under prior art, easily produce the problem of snakelike twisting, and a kind of push-pull valve is provided.
The object of the invention is to be achieved by the following technical programs:
A kind of push-pull valve, comprise valve body, in valve body, be provided with the flashboard being driven by power plant, it is characterized in that valve body bilateral symmetry position arranges respectively dunnage, dunnage is provided with tooth bar, and described flashboard one side is provided with transmission shaft, and transmission shaft two ends arrange respectively a gear, the wheel and rack engagement that cooperatively interacts, described transmission shaft is connected by bearing support and flashboard.
Described valve body inwall symmetrical position arranges respectively guide rail, and corresponding guide rail is connected with flashboard one Slideslip respectively, opens and closes further to ensure that flashboard is stable, prevents that flashboard from swinging.
Described tooth bar is provided with the calibrated scale with flashboard conjunction measuring, for measuring the opening degree of flashboard.
Beneficial effect of the present invention is simple in structure, and reliability is high, in producing snakelike twisting, makes valve opening and closing power stable in the time avoiding push-pull valve unlatching, closing operation, has reduced its maintenance rate.
Below just accompanying drawings and embodiment the present invention is further described.
