Existing reversing valve operated by handwheel when in use there are still it is certain the defects of, although existing reversal valve can carry out
Commutation acts on, but since existing structure of reversing valve is complicated, pursues its leakproofness and have led to installing and dismounting inconvenience, and
And the inside of reversal valve can not observe directly condition of commutation from outside, operate so very inconvenient when commutated.
Invention content
The purpose of the present invention is that solve the above-mentioned problems and provides a kind of reversing valve operated by handwheel have dismounting peace
Dress is convenient, the advantages of convenient for observation condition of commutation.
The present invention is achieved through the following technical solutions above-mentioned purpose：A kind of reversing valve operated by handwheel, including valve body, first
Liquid outlet, the second liquid outlet and inlet, it is characterised in that：One end installation threaded rod of the valve body, the one of the threaded rod
End setting turntable, the side installation crank of the turntable, the top of the valve body set first liquid outlet, and described first goes out
The side of liquid mouth sets the second liquid outlet, the bottom setting inlet of the valve body, the other end setting pedestal of the valve body, institute
State the other end setting push rod of threaded rod, one end setting driving column of the push rod, the first card of outer wall setting of the driving column
Block, the side of first fixture block set the second fixture block, install glass column between first liquid outlet and the second liquid outlet, institute
The both ends for stating glass column are respectively provided with communicating pipe, the inside installation activity plate of the glass column, the bottom setting bullet of the driving column
Spring, the top installation head cover of the driving column, the bottom of the head cover are threaded connector, and the inside installation of the driving column is solid
Determine bolt, the head cover is movably connected by nipple and driving column, and push rod is connected across head cover with fixing bolt, described
Crank is by the way that, in being rotatablely connected, and crank is mounted remotely from the side of center of turntable, described first goes out between turntable and threaded rod
Liquid mouth between glass column and the second liquid outlet by being interconnected, and be movably connected between movable plate and glass column, the biography
Dynamic column is connected, and driving column is connected by push rod with threaded rod by spring with pedestal, and the size of second fixture block is big
In second liquid outlet, and the first fixture block is arranged close to the side of the first liquid outlet.
Preferably, it is connected between the inlet and the first liquid outlet and the second liquid outlet.
The beneficial effects of the invention are as follows：
1st, by setting head cover at the top of driving column, head cover is mounted on by nipple on driving column, and push rod
Bottom stretch into head cover installation fixing bolt, push rod fixation can be prevented in transverse shifting by driving column by fixing bolt
When come off from push rod, cause inconvenient for use, the length of the second fixture block of driving column side in this way may be used much larger than the first fixture block
The second liquid outlet can be blocked with short-range adjusting threaded rod so that it is more convenient when adjusting, improve reversal valve
Sensitivity.
2nd, the configuration of the present invention is simple, connection is compact, by installing a glass between the first liquid outlet and the second liquid outlet
Glass column, glass column are connected by communicating pipe with the first liquid outlet and the second liquid outlet, the inside setting movable plate of glass column, living
Movable plate, which is sticked into just inside glass column, to carry out laterally movable, and when the first liquid outlet is closed, movable plate is due to the second liquid outlet
Pressure is moved towards the first liquid outlet, otherwise is moved towards the second liquid outlet, and solve reversal valve sealing is inconvenient to observe later
Which liquid outlet work the problem of condition of commutation intuitively can know from the position of movable plate.
