Abstract
The utility model discloses an electric and manual valve, comprising a direct current motor, and a speed reducer, which is characterized in that: a manual rotating handle is fixedly arranged out the direct current motor and the speed reducer, the output shaft of the speed reducer is meshed with a valve core arranged in the valve body which is press-assembled on the station structure of the manual rotating bar through a pressure spring. The utility model has the advantages of rational structure, no high-speed rotation between rotor and the stator of the motor when the valve is opened and closed manually, less resistance of opening and closing valve, and less rotor and gear damage, simple structure and reliability.
Description
Technical field:
The utility model relates to a kind of valve.
Background technique:
At many liquid, in the gas automatic control system, electric valve is a kind of indispensable action power unit, but often because system down or cause out of control because of power failure, this moment, electric valve should have manual function, but it is at present existing electronic, the dual-use manual valve mainly contains two kinds: a kind of when being manual motor do not throw off with valve and be connected, direct rotational valve core and retarder shaft, because the general moment of torsion of mortor operated valve is bigger, rotating speed is very low, the retarder no-load voltage ratio is very big, directly rotate the retarder shaft and not only require great effort very much, and make the rotor high speed rotating, damage motor itself and control circuit easily; Retarder broke away from spool when another kind was manual, not can not the changeing of motor commentariess on classics, but on spool, need add manual handgrip in addition, complex structure uses also inconvenience.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and the rotor stator does not have electronic, the dual-use manual valve of relative movement in the time of manually.
Technical solution of the present utility model is:
A kind of electronic, dual-use manual valve, comprise direct current generator, retarder, the difference of itself and prior art is: manually revolve being packed in outside direct current generator, the retarder, the output shaft of retarder and spool engagement, spool is contained in the valve body, and valve body is fitted on the platform level structure that manually revolves handle by stage clip.
The utility model is rational in infrastructure, does not manually have high speed rotating between rotor and stator during the open and close valve, and open and close valve resistance is less, and not fragile rotor and gear, need not to install additional manual valve handle simultaneously, directly as manually revolving handle, utilization structure is simple, reliable for the motor outer casing.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is an embodiment's of the utility model a configuration diagram.
Embodiment:
A kind of electronic, dual-use manual valve, comprise direct current generator (1), retarder (2), manually revolve (3) are packed in outside direct current generator (1), the retarder (2), the output shaft of retarder (2) and spool (5) engagement, but axially can be free to slide, spool (5) is contained in the valve body (6), and valve body (6) is pressed to be engaged on by stage clip (4) and manually revolved on the platform level structure of (3).
Working principle of the present utility model is: drive spool (5) rotation by retarder (2) when motor (1) rotates, manually revolve (3) and a valve body (6) this moment and manually revolve (3) are in engagement, when rotating, motor (1) drives spool (5) rotation by retarder (2), this moment, manually choosing was in the relative fixed position to (3) and valve body (6), and motor (1) clockwise and anticlockwise can be finished the switch valve action.When needing the hand switch valve, to manually revolve (3) will be depressed towards valve body (6) direction, make manually to revolve (3) and valve body (6) are broken away from engagement, retarder this moment (2) still is in engagement with spool (5), retarder (2) rotates simultaneously when manually revolving (3) rotation, drive spool (5) rotation, finish manual open and close valve event.
Claims (1)
1, a kind of electronic, dual-use manual valve, comprise direct current generator (1), retarder (2), it is characterized in that: manually revolve (3) and be packed in outside direct current generator (1), the retarder (2), the output shaft of retarder (2) and spool (5) engagement, spool (5) is contained in the valve body (6), and valve body (6) is fitted in by stage clip (4) and manually revolves on the platform level structure of (3).
