[0035] Please refer to Figures 1-9, the present invention provides a technical solution: a double ram blowout preventer that is easy to disassemble, repair, and can be quickly installed. As shown in Figure 1 , Figure 2 and Figure 3 , it includes a blowout preventer structure 1. The blowout preventer structure 1 includes a blowout preventer housing 11. A disassembly and assembly component 12 is rotatably connected to the blowout preventer housing 11. A double ram blowout preventer body 13 is embedded in the blowout preventer housing 11. A first liquid inlet pipe 14 and a first liquid outlet pipe 15 are communicated with the double ram blowout preventer body 13. The first liquid outlet pipe 15 is located above the first liquid inlet pipe 14. The disassembly and assembly component 12 includes a first fixing plate 121. A rotating ring 122 is rotatably connected between the first fixing plates 121. A sealing cover 123 is fixed on the rotating ring 122. The sealing cover 123 is detachably installed on the double ram blowout preventer body 13 through bolts 124;

[0036] Among them, the telescopic structure in this application is a hydraulic cylinder. The hydraulic cylinder is a prior art. Two sets of disassembly and assembly components 12 are provided. The two sets of disassembly and assembly components 12 are symmetrically arranged, so as to quickly disassemble and install the double ram blowout preventer;

[0037] Specifically, two sets of first fixing plates 121 are provided. The two sets of first fixing plates 121 are symmetrically arranged. Three bolts 124 are provided on the sealing cover 123. The three bolts 124 are equidistantly distributed on the sealing cover 123;

[0038] In the above solution, the fluid enters the double ram blowout preventer body 13 through the first liquid inlet pipe 14, and the liquid is discharged through the first liquid outlet pipe 15 on the double ram blowout preventer body 13. The staff rotates the bolts 124, and the bolts 124 are disassembled from the sealing cover 123 and the blowout preventer housing 11 on the double ram blowout preventer body 13. The sealing cover 123 is rotated, and with the assistance of the rotating ring 122 on the first fixing plate 121, the sealing cover 123 is driven to rotate, so as to disassemble the gate valve plate in the double ram blowout preventer body 13.

[0039] As shown in Figure 1 , Figure 2 , Figure 4 and Figure 4 , an auxiliary sealing and temperature regulating structure 2 is embedded in the blowout preventer structure 1. The auxiliary sealing and temperature regulating structure 2 includes a water guide pipe 21. The water guide pipe 21 is communicated with a temperature regulating component 24 through a first drain pipe 22. The temperature regulating component 24 is communicated with the water guide pipe 21 through a first water inlet pipe 23. A heat dissipation component 25 is fixed on the temperature regulating component 24. The temperature regulating component 24 includes a first heating box 241. The first heating box 241 is communicated with a second heating box 244 through a second water inlet pipe 242.

A heat dissipation fan 253 penetrates through the second fixing plate 251. A heat conducting plate 252 is fixed on the surfaces of the first heating box 241 and the second heating box 244;

[0040] Among them, the water level sensor 243 is of the HM21 model, the temperature sensor is of the CWDZ11 model. The temperature sensor is fixed on the inner walls of the first heating tank 241 and the second heating tank 244. Heat conducting plates 252 are attached to the first heating tank 241 and the second heating tank 244. Multiple groups of heat dissipation fans 253 penetrate through the second fixing plate 251. The multiple groups of heat dissipation fans 253 are equidistantly distributed on the first heating tank 241 and the second heating tank 244, so that the heat dissipation fans 253 dissipate heat from the liquid in the first heating tank 241 and the second heating tank 244. Electric heating wires are embedded in the first heating tank 241 and the second heating tank 244, and the setting of the electric heating wires raises the temperature in the first heating tank 241 and the second heating tank 244;

[0042] In the above solution, with the assistance of the electric heating wire in the second heating tank 244, the liquid in the second heating tank 244 is heated. The heated liquid enters the interior of the water guide pipe 21 through the first water inlet pipe 23. The liquid heated in the water guide pipe 21 conducts heat to the fluid in the well pipe, avoiding the freezing of the fluid with too low temperature and affecting the normal use of the whole device. The used liquid enters the interior of the first heating tank 241 through the first drain pipe 22 and is heated with the assistance of the electric heating wire in the first heating tank 241. The heated liquid enters the interior of the second heating tank 244 through the second water inlet pipe 242 for convenient recycling. In the hot summer, the cooled water is stored in the first heating tank 241 and conducts heat with the assistance of the heat conducting plate 252. With the assistance of the heat dissipation fans 253 on the second fixing plate 251, the liquid is cooled, so as to ensure the cooling of the liquid in the pipeline in the double ram blowout preventer body 13, thus avoiding the pressure increase caused by the too high temperature of the liquid in the pipeline in the double ram blowout preventer body 13, resulting in seal failure and thus causing a blowout accident.
