The beneficial effects of the present utility model:

The remote automatic control mud valve group provided by the utility model, through the electric actuator installed on the high pressure mud valve, when the mud valve needs to be opened for mud transportation, the remote control electric actuator is used to make the actuator work, thereby rotating the mud valve Turn on the screw on the top, open the valve on the corresponding channel, keep the mud inlet and mud outlet in circulation until the display is fully open, and then turn on the mud pump to pour the mud. The structure can greatly save the labor of workers and improve drilling efficiency.

Secondly, this remote self-control mud valve group can adjust the stroke of the mud valve screw, so that the mud valve will not be damaged due to excessive opening or closing, which has a good protective effect on the valve.

Finally, the electric actuator mechanism of the remote automatic control mud valve group is provided with a hand-electric switching handle, which can be switched to manual mode in the case of power failure. Turning the handwheel can also realize the opening or closing of the valve; and the structure cost is low, and the control convenient.

Detailed ways

The present utility model will be described in further detail below in conjunction with the accompanying drawings.

As shown in Figures 1, 2 and 3: a remote automatic control mud valve group, including 8 high-pressure mud valves 13 installed on the base 4, the mud valve 13 is provided with a mud inlet 1 on the left side, and the mud valve 12 is provided on the right side respectively. There are a three-way 10, a four-way 7, a mud outlet 8, and an electric actuator 3 is provided on the top of the mud valve 13.

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

A union 6 for connection is provided between the mud valve 13 and the mud inlet 1 , the mud outlet 8 , the three-way 10 and the four-way 7 .

The safety valve 2 and the mud inlet 1 are connected by flanges.

A flange 15 for connecting the electric actuator 3 is provided between the mud valves 13 .

The electric actuator 3 is an explosion-proof electric device with a travel control switch inside and a hand-electric switching handle outside.

The working principle of the present utility model:

As shown in Figure 4 and Figure 5: When the remote automatic control mud valve group works, first the valve group is fixed on the base 4, and then the electric actuator 3 is installed on the modified mud valve 13 through the flange 15, and set in manual mode. Check the stroke of the electric actuator 3 so that the adjusted stroke can just make the mud valve 13 fully open or fully closed. After the adjustment, the electric actuator 3 is powered on, switched to the electric mode, and the mud pump and mud channel to be opened are selected. For example, mud pump 2 and mud channel 1, first select the 2#, 6#, and 7# mud valves that need to be opened. When the indicator light is on, it means that the valve has been fully opened, and then close the other 5 mud valves. When the indicator light "closes in place" is on, it means that the valve has been completely closed. At this time, the No. 1 mud channel has been set up. Turn on the No. 1 pump to input the mud and start the drilling operation. When the mud pump is working, when abnormal high pressure is generated due to the obstruction of the mud channel, the pressure reaches the safety pressure set by the safety valve. At this time, the safety valve is automatically opened, so that the mud flows back into the mud tank through the safety valve to ensure drilling. Work safely.

The base 4 of the present design can replace the fixing supports 9 of different sizes according to the size of different pipe diameters, and the pipes are fixed by bolts. The designed electric actuator 13 can turn the switch handle 14 to switch to the manual mode when the power is turned off. At this time, by manually turning the handwheel of the electric actuator 13, the operation of opening or closing the valve can also be realized. When the pipeline pressure needs to be released, simply open the pressure relief port 5 mud channel to release the pipeline pressure. The control system of the remote self-control mud valve group can realize the self-checking function. When the electric actuator 13 fails, the system will automatically alarm and light up the red fault light. All cables pass through the bottom of the base through the wiring hole 11 , which ensures the cleanliness of the upper part of the base 4 and protects the cables at the same time.
