Abstract
A blowout preventer pressure testing device control box for pressure testing of pressure devices of petroleum drilling blowout preventers consists of an electrical master switch, a plug-in type protective tube fuse, an intermediate relay, a connecting terminal, an AC contactor for controlling an electric pump, an AC contactor for controlling a water pump and a control box outer casing. An intermediate relay connection diagram includes supercharging, collar clamp opening, collar clamp closing, cylinder lifting, cylinder dropping, a sensor, a small collar clamp, a large collar clamp and electromagnetic valves. The electrical master switch, the plug-in type protective tube fuse, the intermediate relay, the connecting terminal, the AC contactor for controlling an electric pump and the AC contactor for controlling a water pump are all arranged in the control box outer casing and in electrical connection. The intermediate relay connection diagram includes that supercharging and the electromagnetic valve, collar clamp opening and the electromagnetic valve, collar clamp closing and the electromagnetic valve, cylinder lifting and the electromagnetic valve, cylinder dropping and the electromagnetic valve, and the sensor and the electromagnetic valve are all in circuit connection with the small collar clamp and the large collar clamp. The control box resolves problems that automatic switching can not be realized in the prior art, which is not favorable for safety pressure testing. The control box is used for pressure testing of blowout prevention pressure testing devices for petroleum drilling.
Description
Technical field:
The utility model relates to the preventer pressure testing device control box that the pressure testing of a kind of petroleum drilling preventer pressure testing device is used.
Background technology:
The petroleum drilling preventer prevents gas blowout accident, it is the visual plant that guarantees drilling safety, this utensil is before situ of drilling well is installed, will carry out pressure testing to its performance and detect, the preventer pressure testing device generally all has control box when producer buys, and what have does not have a control box yet, therefore need design new control box according to the preventer pressure testing device, existing control box can not be realized automatic conversion, is unfavorable for safe pressure testing, for this reason.We have developed a kind of preventer pressure testing device control box through practice, and trial effect is good.
The utility model content:
The purpose of this utility model provides a kind of preventer pressure testing device control box, and it has solved the original control box that exists in the prior art can not realize automatic conversion, is unfavorable for the problem of safe pressure testing.
The technical scheme that its technical matters that solves the utility model adopts is: preventer pressure testing device control box, by electric master switch, plug-in type protective tube fuse, auxiliary reclay, connection terminal, control electric pump A.C. contactor, control water pump A.C. contactor, the control box shell, auxiliary reclay connection layout: supercharging, clip is opened, clip closes, the liter of taking blame for others, take blame for others and fall, sensor, little clip, big clip, solenoid valve is formed: with electric master switch, plug-in type protective tube fuse, auxiliary reclay, connection terminal, control electric pump A.C. contactor, control water pump A.C. contactor all is contained in the control box shell, and each parts is circuit and connects; In the auxiliary reclay connection layout: supercharging and solenoid valve, little clip, big clip; Clip is opened and solenoid valve, little clip, big clip; Clip closes and the little clip of solenoid valve, big clip; Take blame for others and rise and solenoid valve, little clip, big clip; Take blame for others and fall and solenoid valve, little clip, big clip; Sensor and solenoid valve, little clip, big clip.Being circuit between them connects.
The beneficial effects of the utility model are: this control box is simple in structure, and is easy to operate, improves pressure testing quality and fiduciary level; Avoid the manually-operated conversion valve to cause error, improved the serviceable life of equipment under test; Maintenance is convenient, satisfied to greatest extent save time, the labour-saving demand.
