Abstract
The utility model provides an electric flap valve driven by a crankshaft, which has the advantages of small structure size and convenient installation. The electric flap valve comprises a driving arm, driven arms, heavy hammer arms, a heavy hammer and a valve plate, wherein, the driving arm is connected with an output shaft of a speed reducer; the heavy hammer is arranged at the top ends of the heavy hammer arms; Two driven arms and two heavy hammer arms are respectively connected with an upper valve plate shaft and a lower valve plate shaft, and symmetrically arranged along the driving arm. The electric flap valve has the advantages of small structure size, convenient installation, easy maintenance, low cost and smart size.
Description
Technical field
The utility model relates to a kind of electric rotating plate valve, is specifically related to a kind of with crank drive electric rotating plate valve.
Background technique
The electric rotating plate valve is by applying power, make the weight lifting that is connected with valve plate and open valve, falling and throttle down by the weight own wt.The available dynamic kind of drive is cam drive, and physical dimension is bigger, and inconvenience is installed.
Summary of the invention
The purpose of this utility model is in order to solve the deficiencies in the prior art, to provide a kind of physical dimension little, usefulness crank drive electric rotating plate valve easy for installation.
The technical solution of the utility model is: a kind of with crank drive electric rotating plate valve, comprise master arm, slave arm, weight arm, weight and valve plate, described master arm is connected with the speed reducer shaft, weight is located at the top of weight arm, slave arm and weight arm are two, are connected on the upper and lower valve shaft, and arrange along the master arm axisymmetric, when the drive end of slave arm arrived peak under master arm drives, valve was just opened fully.
The utility model adopts crank drive, when unpowered applying, valve is in closed condition, when master arm upwards turns to when contacting with slave arm, last valve plate begins to start, when slave arm turned to peak, last valve was opened fully, and master arm continues to rotate, master arm and slave arm break away from, this moment, slave arm was got back to original position under weight deadweight effect, and last valve plate also will be gone up valve closing again; When master arm is swung down to when contacting with slave arm, same working principle, the opening and closing of lower valve experience go round and begin again, and master arm whenever turns around, and each work of the upper and lower slave arm of driven is once.
The drive end of master arm and slave arm can adopt rolling bearing, and rolling bearing life is long, need not to lubricate, and rolling bearing is standard piece, is easy to buy, and also is convenient to change.
The beneficial effects of the utility model are: physical dimension is little, easy for installation, easy to maintenance, cost is low, size is light and handy.
