Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, fig. 2, fig. 3: the utility model provides a long-range automatic control mud valve group, is provided with electric actuator 3 including installing 8 high-pressure mud valves 13 on base 4, mud valve 13 left side is provided with mud import 1, and mud valve 12 right side is provided with tee bend 10, cross 7, mud export 8 respectively, and mud valve 13 top.

The base 4 is respectively provided with a valve group lifting lug 12, a pipeline fixing support 9 and an electric actuator 3 wiring hole 11.

And a union 6 for connection is arranged between the slurry valve 13 and the slurry inlet 1, the slurry outlet 8, the tee joint 10 and the four-way joint 7.

The safety valve 2 is connected with the slurry inlet 1 through a flange.

The electric actuator 3 is an explosion-proof electric device, a travel control switch is arranged in the electric actuator, and a manual-electric switching handle is arranged outside the electric actuator.

The utility model discloses a theory of operation:

as shown in fig. 4 and 5: when the remote self-control mud valve group works, firstly, the valve group is fixed on a base 4, then an electric actuator 3 is arranged on a modified mud valve 13 through a flange 15, the stroke of the electric actuator 3 is set under a manual mode, so that the regulated stroke can just enable the mud valve 13 to be fully opened or fully closed, after regulation is finished, the electric actuator 3 is electrified and switched to an electric mode, a mud pump and a mud channel which need to be opened are selected, such as a mud pump 2 and a mud channel 1, the 2#, 6#, and 7# mud valves which need to be opened are selected firstly, when an indicator lamp is turned on in place, the valves are completely opened, then other 5 mud valves are closed, when the indicator lamp is turned off in place and is turned on, the valves are completely closed, at the moment, the mud channel No. 1 is set, and the input of mud can be carried out by opening the pump No. 1, and (5) performing drilling operation. When the mud pump works and abnormal high pressure is generated due to the fact that a mud channel is blocked and the like, the pressure reaches the safety pressure set by the safety valve, the safety valve is automatically opened at the moment, mud flows into the mud tank again through the safety valve, and the safe operation of drilling is guaranteed.

The base 4 of this design can change not unidimensional fixing support 9 according to the size of different pipe diameters to it is fixed with the pipeline through the bolt. The designed electric actuator 13 can rotate the switching handle 14 under the condition of power failure to enable the switching handle to be switched to a manual mode, and at the moment, the operation of opening or closing the valve can be realized by manually rotating the hand wheel of the electric actuator 13. When the pipeline pressure needs to be released, the pipeline pressure can be released only by opening the pressure relief port 5 and the slurry channel. The control system of the remote automatic control mud valve group can realize a self-checking function, and when the electric actuator 13 fails, the system can automatically alarm and light a red fault lamp. All cables pass through from the base bottom through wiring hole 11, have guaranteed the clean and tidy on base 4 upper portion promptly, have played the effect of protection cable again simultaneously.
