Abstract
The utility model provides a manual flat valve with double-screw synchronous drive, which has the advantages of reasonable structure and labor-saving operation. The manual flat valve comprises a valve plate, screws, a hand wheel, a synchronous mechanism, a chain and a chain wheel, wherein, the hand wheel is arranged at one end of the screws, and the valve plate is arranged at the other end of the screws; the two screws are parallelly and symmetrically arranged along the middle shaft; the synchronous mechanism is arranged between the two screws, and comprises the chain and the chain wheel.
Description
Technical field
The utility model relates to a kind of manual dull and stereotyped valve, is specifically related to the manual flap type of a kind of double lead Synchronous Transmission.
Background technique
General manual dull and stereotyped valve aperture is less, adopts the transmission of monofilament bar usually, and if adopt the transmission of monofilament bar for the bigger manual dull and stereotyped valve of bore, will occur manual operation painstaking, drive situation of difficult.
Summary of the invention
The purpose of this utility model is in order to solve the deficiencies in the prior art, and a kind of manual flap type of double lead Synchronous Transmission of rational in infrastructure, rapid operation is provided.
The technical solution of the utility model is: the manual flap type of a kind of double lead Synchronous Transmission, comprise valve plate, screw mandrel, handwheel, lazy-tongs, chain and sprocket wheel, described screw mandrel one end is provided with handwheel, an end connects valve plate, screw mandrel is two, and be symmetrical arranged along axis is parallel, be provided with lazy-tongs between the screw mandrel, lazy-tongs comprise chain and sprocket wheel.
Because the existence of lazy-tongs, two handwheels can rotate simultaneously, make the transmissions simultaneously of two screw mandrels to drive the opening and closing of valve plate, both can one man operation, also can two people operation, and solved the manual problem that is difficult to drive of large caliber flat plate valve.
The beneficial effects of the utility model: 1, rational in infrastructure; 2, rapid operation.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As shown in drawings: the manual flap type of a kind of double lead Synchronous Transmission, comprise valve plate 1, screw mandrel 2, handwheel 3, lazy-tongs 4, chain 5 and sprocket wheel 6, described screw mandrel 2 one ends are provided with handwheel 3, an end connects valve plate 1, screw mandrel 2 is two, and be symmetrical arranged along axis is parallel, be provided with lazy-tongs 4 between the screw mandrel 2, lazy-tongs 4 comprise chain 5 and sprocket wheel 6.
