Abstract
The utility model relates to a reversing valve, and belongs to the field of industrial devices. The reversing valve comprises a valve body, and is characterized in that a cylinder base is arranged on the upper part of the valve body; the upper part of the cylinder base is connected with a cylinder; a valve cover is arranged on the lower part of the valve body and is connected with the cylinder by a valve cover shaft; a fluororubber seal ring is arranged between the valve cover and a valve cover plate arranged on the lower part of the valve cover; and a coil of an electromagnetic valve of the cylinder is connected with a programmable logic controller (PLC). According to the reversing valve, the reversing is controlled by pneumatic power, and the reversing time is controlled by a PLC system, so that the requirement of arbitrarily set reversing time of a project can be met; because the reversing valve is sealed by the fluororubber seal ring, air tightness and stable pressure in a reversing process are realized; and moreover, the reversing valve can resist to a high temperature which can reach over 200 DEG C, so that high-temperature control reversing can be realized. The reversing valve has the appearance in a box body structure, and is easy to manufacture and reliable to use.
Description
Technical field
The utility model relates to a kind of selector valve, belongs to the commercial plant field.
Background technique
Selector valve of the prior art generally can not be adjusted turn around time arbitrarily, has caused many inconvenience to production, has increased cost, has reduced working efficiency.
The model utility content
According to above deficiency of the prior art, the utility model technical problem to be solved is: a kind of employing pneumatic control switching-over is provided, can satisfy that engineering sets arbitrarily turn around time demand selector valve.
The utility model solves the technological scheme that its technical problem adopted:
Described selector valve; Comprise valve body, its characteristics are: valve body top is provided with air cylinder base, and air cylinder base top connects cylinder; Valve body lower portion is provided with valve gap; Valve gap and cylinder are linked together by the valve gap axle, between the valve cover that valve gap and bottom are provided with viton seal ring are set, and the coil of cylinder solenoid valve links to each other with the PLC controller.
Described valve body supports air cylinder base, and cylinder is placed in above the air cylinder base by the bolt connection, and the valve gap axle is connected the drive valve gap and moves up and down with cylinder.
PLC controller control: the coil of PLC controller control cylinder solenoid valve, when coil gets when electric, cylinder is opened; When coil losing electricity, cylinder is closed.On cylinder, be provided with upper and lower control magnetic switch, when cylinder was opened, the upper limit magnetic switch had signal, and the expression cylinder is opened; When cylinder was closed, the lower limit magnetic switch had signal, and the expression cylinder is closed.When getting electric 5 seconds when cylinder solenoid valve, upper limit magnetic switch no signal, the PLC controller sends malfunction alarm; When cylinder solenoid valve dead electricity after 5 seconds, lower limit magnetic switch no signal, the PLC controller sends malfunction alarm.
Above-mentioned is the situation of one group of unit, and two groups of identical unit can be set in the described selector valve, has improved working efficiency.
The beneficial effect that the utility model had is:
The utility model adopts the pneumatic control switching-over, and can satisfy turn around time demand that engineering arbitrarily set by the control of PLC controller turn around time; Seal by viton seal ring, realized central air tight, the pressure stability of commutation process, and high temperature resistant degree, can reach more than 200 degree, can realize the high-temperature control switching-over.The profile of the utility model adopts housing structure, makes simply, uses reliable.
