The side wall of the first connecting block is provided with an installation groove, and the interior of the installation groove is provided with a connecting mechanism. The inner side wall of the gate block is provided with a clamping mechanism, and the top of the gate block is provided with a closing mechanism.
[0007] As a further improvement of this utility model, the connecting mechanism includes two locking blocks disposed inside the mounting groove, a spring disposed between the two locking blocks, and the two ends of the spring being fixedly connected to the two locking blocks respectively. The inner walls on opposite sides of the second connecting block are provided with locking grooves that cooperate with the locking blocks.
[0008] As a further improvement of this utility model, the clamping mechanism includes a second hydraulic rod fixedly installed on the inner wall of the gate block, and an arc-shaped clamping plate is fixedly connected to the telescopic end of the second hydraulic rod.
[0009] As a further improvement of this utility model, the closing mechanism includes a closing plate disposed inside the gate block, the closing plate penetrating the inner wall of the gate block and being slidably connected to the gate block, a slider fixedly connected to the upper end of the closing plate, and sliding grooves provided on the inner walls of the two opposite sides of the gate block, the two ends of the slider being slidably connected to the two sliding grooves respectively, and a first hydraulic rod installed on the outer wall of the gate block, the telescopic end of the first hydraulic rod penetrating the gate block and being fixedly connected to the side wall of the slider.
[0010] As a further improvement of this utility model, a lever is fixedly connected to the side wall of the card block.
[0011] As a further improvement of this utility model, the two gate blocks are rotatably connected by two hinges.
[0012] The beneficial effects of this utility model are:
[0013] By setting up a hinge, a first connecting block, a second connecting block, and a connecting mechanism, the two gate blocks can be quickly connected and installed by connecting the first connecting block to the inside of the second connecting block and inserting the card block into the inside of the card slot.
[0014] By setting up a closing mechanism, the first hydraulic rod is extended, which drives the slider to move inside the groove. The slider then drives the closing plate to move, enabling the closing plate to close quickly and effectively preventing the rapid leakage of gas from the tubing and the occurrence of a blowout.
[0015] This invention enables the quick connection and installation of two gate blocks, effectively preventing the rapid leakage of gas from the tubing and thus preventing blowouts. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-4The pressurized operation gate blowout preventer includes two gate blocks 1, which are rotatably connected and rotatably connected by two hinges 10. A first connecting block 6 and a second connecting block 7 are fixedly connected to the side walls of the two gate blocks 1 respectively. The side wall of the first connecting block 6 is provided with an installation groove 13, and the interior of the installation groove 13 is provided with a connecting mechanism. The inner side wall of the gate block 1 is provided with a clamping mechanism, and the top of the gate block 1 is provided with a closing mechanism.
[0023] In this utility model, the connecting mechanism includes two locking blocks 12 disposed inside the mounting groove 13, and a spring 15 disposed between the two locking blocks 12. The two ends of the spring 15 are respectively fixedly connected to the two locking blocks 12. The inner walls on both sides of the second connecting block 7 are provided with locking grooves 11 that cooperate with the locking blocks 12.
[0024] The clamping mechanism includes a second hydraulic rod 8 fixedly installed on the inner wall of the gate block 1. The telescopic end of the second hydraulic rod 8 is fixedly connected to an arc-shaped clamping plate 9. When the second hydraulic rod 8 is activated, it extends and drives the arc-shaped clamping plate 9 to clamp onto the tube column.
[0025] The closing mechanism includes a closing plate 2 disposed inside the gate block 1. The closing plate 2 penetrates the inner wall of the gate block 1 and is slidably connected to the gate block 1. A slider 4 is fixedly connected to the upper end of the closing plate 2. Slide grooves 5 are provided on the inner walls of the two opposite sides of the gate block 1. The two ends of the slider 4 are slidably connected to the two slide grooves 5 respectively. A first hydraulic rod 3 is installed on the outer wall of the gate block 1. The telescopic end of the first hydraulic rod 3 penetrates the gate block 1 and is fixedly connected to the side wall of the slider 4. A lever 14 is fixedly connected to the side wall of the locking block 12. When the first hydraulic rod 3 is activated, it extends and drives the slider 4 to move inside the slide groove 5. The slider 4 drives the closing plate 2 to move, which enables the closing plate 2 to close quickly and effectively prevents the gas inside the tubing from leaking out rapidly and causing a blowout.
[0026] In use, this invention allows for the rapid connection and installation of two gate blocks 1 by rotating the two gate blocks 1, connecting the first connecting block 6 to the inside of the second connecting block 7, and inserting the locking block 12 into the slot 11. The second hydraulic rod 8 is then extended, causing the arc-shaped clamping plate 9 to hold the tubing. The first hydraulic rod 3 is then extended, causing the slider 4 to move inside the groove 5. The slider 4 moves the closing plate 2, enabling it to close quickly and effectively preventing rapid gas leakage from the tubing, thus preventing a blowout.
[0027] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
