Abstract
The utility model discloses a ball valve with a switch indicating device. The ball valve comprises a valve body, a valve cover, a valve seat, a ball body, a valve rod and an operating mechanism, wherein a valve rod sleeve is arranged on the valve body; the valve rod penetrates through the valve rod sleeve, the inner end of the valve rod stretches into the valve body and is in linkage fit with the ball body, and the outer end of the valve rod extends out of the valve rod sleeve and is fixedly connected and matched with the operating mechanism; four proximity switches are distributed on the outer end face of the valve cover in a cross shape relative to the periphery of the valve rod; an indicating dial is sleeved at the outer end of the valve rod in a linkage mode; a contact rod in contact fit with the proximity switches is arranged on the indicating dial; the switch indicating device comprises a proximity switch controller; the proximity switch controller is in control connection with the proximity switches; a display screen used for displaying a switching state is in output control connection with the proximity switch controller. The ball valve has the advantages that the switch indicating effect is good, and an electric and automatic control function can be realized.
Description
Technical field
The utility model relates to a kind of ball valve, specifically refers to a kind of ball valve with switch indicating device.
Background technique
Ball valve is a kind of valve of present extensive use, and existing ball-valve structure generally comprises valve body, valve gap, spheroid and valve rod, operating device, and wherein operating device and valve rod are linked, and actuate valve stem drives spheroid and rotates, and finishes the switching motion of ball valve.The open/close states of existing ball valve all be to judge by the position of valve rod at present, but ball valve is in actual application; valve rod often can be removed, and to prevent misoperation, causes thus; the operator is difficult to accurate understanding to the open/close states of ball valve, has awkward shortcoming.
Summary of the invention
The purpose of this utility model is the shortcoming and defect that exists in order to overcome prior art, and provides a kind of switch indication accurately to understand, the ball valve with switch indicating device easy to use.
For achieving the above object, the technical solution of the utility model is to include valve body, valve gap, valve seat, spheroid and valve rod and operating device, described valve body upper valve rod cover, valve rod passes valve stem casing, its the inner is stretched in the valve body and with spheroid and is linked, its outer end is stretched out valve stem casing and is fixedly connected with operating device and cooperates, the crossing distribution all around of relative valve rod has four approach switchs on the exterior edge face of described valve gap, the outer end interlock of described valve rod is arranged with indicator panel, be provided with the contact lever that cooperates with the approach switch touching on this indicator panel, described switch indicating device includes the approach switch controller, this approach switch controller and approach switch control connection, and export the display screen that control connection is useful on the display switch state on this approach switch controller.
By this setting, utilize approach switch corresponding to contact lever touching, and by the on off state of approach switch controller at display screen demonstration ball valve, indicating effect is good.
Further arranging is to be connected with relay on the described approach switch controller, and described operating-controlling mechanism is electric actuator, this relay and electric actuator control connection.By this setting, so that the utility model can carry out control break to the on off state of ball valve by the approach switch controller, realized automatic operation.
In sum, the utility model has the advantages that the switch indicating effect is good, and can realize electronic automatic control function.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.
