Abstract
The utility model discloses a kind of oily Water control valve device with position control, by control panel, return of stroke valve, solenoid directional control valve, oily water control valve, hydraulic pressure operates cylinder, inlet valve valve forms, it is effectively prevent the sealing damage of inlet valve valve caused by malfunctioning because of oily Water control valve device, realizes the movement of the hydraulic pressure operation cylinder of oily water control valve control and the mechanical latching relationship of inlet valve valve position.
Description
Technical field
The utility model relates to a kind of oily Water control valve device with position control.
Background technique
In power station, the seal operation of inlet valve valve operates cylinder using the hydraulic pressure of oily Water control valve device operation.When into
When water valve valve rotates, the sealing of valve, which necessarily is in, exits position, if the sealing of valve is miscarried into will cause sealing surface
Serious damage.In existing hydraulic pressure operation cylinder control device, closed only with the closed position electric signal of inlet valve valve
Lock form, without the closed position mechanical latching relationship with inlet valve valve.
According to above situation, invent a kind of oily Water control valve device with position control, realize the movement of hydraulic pressure operation cylinder with
The position mechanical latching relationship of inlet valve valve.
Summary of the invention
The purpose of this utility model provides a kind of oily Water control valve device with position control.The technology that the utility model uses
Scheme is: operating cylinder (5), water inlet by control panel (1), return of stroke valve (2), solenoid directional control valve (3), oily water control valve (4), hydraulic pressure
Valve valve (6) composition, wherein control panel (1) is fixed on inlet valve valve (6) and with inlet valve valve (6) together around fixing axle
Rotation, the control mouth B of return of stroke valve (2) are connected with the pressure oil port P of solenoid directional control valve (3), the control of solenoid directional control valve (3)
Hydraulic fluid port A is connected with the control chamber of oily water control valve (4), and two control chambers A, B of oily water control valve (4) operate cylinder (5) with hydraulic pressure respectively
Two control chambers O, C connection.
The characteristics of the utility model, is:
Using the inlet valve valve band control panel form rotated around fixing axle, realize only when inlet valve valve is in close stance
When setting, can operating hydraulic pressure operation cylinder investment inlet valve valve sealing make when inlet valve valve is in non-closed positions
The sealing of inlet valve valve realizes mechanical latching relationship in state of a control is exited, and effectively prevent caused by malfunctioning because of oily water control valve
Inlet valve valve sealing damage.
Detailed description of the invention
Fig. 1 is the organization chart of the utility model；
Specific embodiment
According to Fig. 1, a kind of oily Water control valve device with position control, including control panel 1, return of stroke valve 2, electromagnetism
Reversal valve 3, oily water control valve 4, hydraulic pressure operate cylinder 5, inlet valve valve 6, wherein control panel 1 be fixed on inlet valve valve 6 and with
Inlet valve valve 6 is rotated around fixing axle together, and the control mouth B of return of stroke valve 2 is connected with the pressure oil port P of solenoid directional control valve 3,
The control port A of solenoid directional control valve 3 is connected with the control chamber of oily water control valve 4, two control chambers A, B of oily water control valve 4 respectively with
Hydraulic pressure operates two control chambers O, C connection of cylinder 5.
When inlet valve valve is in the closed position, control panel 1 is rotated with inlet valve valve 6 to pushing down return of stroke valve 2
Triggering rod and push the spool of return of stroke valve 2 to reach the position on right side work functions shown in Fig. 1, pressure oil passes through row at this time
Journey reversal valve 2 reaches solenoid directional control valve 3, can operate the investment that 3 pairs of solenoid directional control valve oily water control valves 4 carry out hydraulic pressure operation cylinder 5
It is controlled with exiting, to control the investment of inlet valve valve sealing and exit.When inlet valve valve is in non-closed positions, work as control
When the triggering rod of making sheet 1 and return of stroke valve 2 is contactless, return of stroke valve 2 is in left position work under the action of itself spring
Make position, pressure oil is truncated, and can not reach solenoid directional control valve 3, the logical oil extraction of P, T of solenoid directional control valve 3, therefore oil control at this time
The control chamber of water valve 4 is only run in oil, makes valve sealing in exiting position and nothing so that oily water control valve 4 controls hydraulic pressure operation cylinder 5
Method investment.
