[0019] Example: Figure 1-6 As shown, the utility model provides a stainless steel valve for an offshore platform, comprising a body 1, both ends of the body 1 are connected with a connecting pipe 11 by bolts, two protective covers 12 are arranged on both sides of the connecting pipe 11, the top of the protective cover 12 is hinged with a cover 13, the edges of both sides of one protective cover 12 are fixedly mounted with a first connecting block 2, the edges of both sides of the other protective cover 12 are fixedly mounted with a second connecting block 20 corresponding to the first connecting block 2, the middle of each first connecting block 2 is provided with a first circular groove 21, the inner portion of the first circular groove 21 is provided with a first connecting block 21, and the inner portion of the first circular groove 21 is provided with a first connecting block 20. A fixed plate 22 is fixedly installed on the top of the second connecting block 20, a first spring 23 is fixedly installed on the top of the fixed plate 22, a top plate 24 is fixedly installed on the top of the first spring 23, a guide rod 25 is rotatably passed through the middle of the fixed plate 22 and the top plate 24, two symmetrically distributed connecting rods 26 are fixedly installed on the outside of the guide rod 25, a handle 27 is fixedly installed on the top of the guide rod 25, a second circular groove 28 corresponding to the first circular groove 21 is opened in the middle of the second connecting block 20, and square grooves 29 are opened on both sides of the second circular groove 28 in the middle of the second connecting block 20.

[0020] One side of the cover 13 is rotatably connected to the rotating plate 3, and a first empty slot 31 is penetrated on one side of the rotating plate 3, and a fixing block 32 used in conjunction with the first empty slot 31 is fixedly installed on one side of one of the protective covers 12 close to the rotating plate 3, and a fixing seat 33 is fixedly installed on one side of one of the protective covers 12 close to the fixing block 32, and a second empty slot 34 is opened inside the fixing seat 33, and a second spring 35 is fixedly installed on the inner wall of the second empty slot 34, and a card column 36 is slidably clamped in the middle of the fixing seat 33, and the card column 36 is slidably clamped in the rotating plate 3, and two symmetrically distributed connecting columns 37 are fixedly installed on the outside of the card column 36, and the second spring 35 is fitted with the connecting column 37, and the connecting column 37 is slidably clamped in the fixing seat 33, and the connecting column 37 is located in the second empty slot 34, and a fixing slot 38 used in conjunction with the connecting column 37 is opened in the middle of the fixing block 32.

[0021] A circular groove 7 having a diameter greater than that of the second circular groove 28 is formed inside each second connecting block 20 . The circular groove 7 is provided to facilitate the rotation of the two connecting rods 26 .

[0022] Two symmetrically distributed semicircular grooves 4 are provided inside each second connection block 20 , and the semicircular grooves 4 and the square grooves 29 are in a cross shape. By providing the semicircular grooves 4 , the first connection block 2 and the second connection block 20 are more stably fixed together.

[0023] A first baffle 5 is fixedly installed on one side of the interior of each circular groove 7, and the first baffle 5 corresponds to the edge of one of the semicircular grooves 4. A second baffle 51 is fixedly installed on the other side of the interior of the circular groove 7, and the second baffle 51 corresponds to the edge of one of the square grooves 29. By setting the first baffle 5 and the second baffle 51, when the handle 27 is rotated, the guide rod 25 and the connecting rod 26 are driven to rotate. When one of the connecting rods 26 is in contact with the first baffle 5, it means that the semicircular groove 4 corresponds to the connecting rod 26. Then the handle 27 is released, and under the action of the rebound of the first spring 23, the connecting rod 26 is snapped into the corresponding semicircular groove 4, so that the connecting rod 26 can be snapped into the corresponding semicircular groove 4 more accurately, and the first connecting block 2 and the second connecting block 20 are fixed together. When one of the connecting rods 26 is in contact with the second baffle 51, it means that the connecting rod 26 corresponds to the square groove 29, and the second connecting block 20 and the corresponding protective cover 12 can be separated from the first connecting block 2 and the corresponding protective cover 12, and the two protective covers 12 are not fixed together.

[0024] A placement groove 6 having a diameter larger than the first circular groove 21 is provided on one side of each first connecting block 2 away from the second connecting block 20. The top plate 24 and the handle 27 are located in the placement groove 6. The placement groove 6 facilitates the placement of the top plate 24 and the handle 27.

[0025] The handle 27 is made of plastic, which increases the comfort between the hand and the handle 27 and makes it easier to turn the handle 27.

[0026] The length and height of the first slot 31 are both longer than those of the fixing block 32 , which makes it easier for the rotating plate 3 to pass through the first slot 31 and fix the cover 13 on the protective cover 12 .

[0027] Working principle: In actual use, when the two protective covers 12 are fixed together and installed on the connecting pipes 11 at both ends, the first connecting block 2 and the second connecting block 20 are aligned, and then the connecting rod 26 and the guide rod 25 are inserted into the corresponding second circular groove 28 and the square groove 29 to make the first connecting block 2 and the second connecting block 20 fit together, and then the handle 27 is turned, and the top plate 24 is pushed forward at the same time, and the first spring 23 is contracted, and then the connecting rod 26 is moved away from the square groove 29 by turning the handle 27. When the connecting rod 26 fits the first baffle 5, the handle 27 is released, and under the rebound action of the first spring 23, the connecting rod 26 is accurately stuck into the corresponding semicircular groove 4, thereby fixing the two protective covers 12 together and fixing them on the connecting pipes 11 at both ends;

[0028] When it is necessary to fix the cover 13 on one of the protective covers 12, the clamping column 36 is pulled in the opposite direction of the fixing block 32, driving the connecting column 37 to move, and the second spring 35 contracts, so that the clamping column 36 is disengaged from the fixing groove 38, and then the rotating plate 3 is rotated to make the first empty groove 31 on the rotating plate 3 pass through the fixing block 32, and at the same time make the rotating plate 3 and the protective cover 12 stick to each other, and then the clamping column 36 is released. Under the action of the rebound of the second spring 35, the connecting column 37 and the clamping column 36 are driven to rebound, so that the clamping column 36 is stuck in the rotating plate 3 and the fixing groove 38, thereby fixing the cover 13 on the protective cover 12.

[0029] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
