Detailed Implementation

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Reference Figure 1-4 This utility model discloses a gas-fired power generation pipeline valve, comprising: a first housing 1, a second housing 2, a gas pipe 3, and a valve body 13. The first housing 1 and the second housing 2 are located on opposite sides of the gas pipe 3. The valve body 13 is connected to the gas pipe 3 via a connecting flange and is located between the first housing 1 and the second housing 2. Both the first housing 1 and the second housing 2 are provided with a through groove 14, a first injection groove 15, and a second injection groove 16. The through groove 14 is located inside the first injection groove 15, and the first injection groove 15 is located inside the second injection groove 16. The first housing 1 is provided with an injection pipe 4 and an injection tube 5. Pipe 2 5, injection pipe 1 4 and injection pipe 2 5 are respectively connected to injection tank 1 15 and injection tank 2 16. A box body 6 is fixedly connected to the side surface of the shell 2. A piston plate 17 is provided inside the box body 6. There are two piston plates 17, and a connecting column 18 is fixedly connected between the two piston plates 17. Pigment water is installed above the upper piston plate 17. A cover plate 8 is detachably connected to the upper surface of the box body 6. A transparent hollow column 11 is fixedly connected to the upper surface of the cover plate 8. A pressure relief valve 12 is provided on the upper surface of the transparent hollow column 11 and is connected to the transparent hollow column 11.

[0021] Specifically, after the gas pipe 3 is connected to the valve body 13, housing 1 and housing 2 wrap the valve body 13 and the connection between the valve body 13 and the gas pipe 3. Upon completion of installation, sealant is injected into the injection groove 15 and injection groove 26 through injection pipe 4 and injection pipe 25 to achieve a sealing effect. The double-layer design further enhances the sealing effect and reduces leakage. In the event of a leak in the valve body 13 or the connection between the valve body 13 and the gas pipe 3, the leaked gas passes through the area between housing 1 and housing 2 and the valve body 13 and the gas pipe 3. The gas enters the channel 14. Since the channel 14 of the housing 2 is connected to this area, the gas can smoothly enter the channel 14. When the pressure in the channel 14 is high, it will push the piston plate 17 in the box 6 to rise, thereby putting the pigment water above the piston plate 17 into the transparent hollow column 11, so that people can notice it in time. The air in the transparent hollow column 11 is discharged through the pressure relief valve 12. At the same time, due to the setting of the double-layer piston plate 17 and the cover plate 8, the piston plate 17 is blocked, thereby preventing gas leakage after the pigment water is discharged.

[0022] Fixing blocks 1 and 9 are fixedly connected to the side surfaces of the box body 6 and the cover plate 8. Fixing blocks 2 and 19 are fixedly connected to the side surfaces of the shell 1 and the shell 2. Fixing blocks 1 and 9 are fixedly connected by bolts. A liquid injection pipe 10 is fixedly connected to the upper surface of the cover plate 8. The liquid injection pipe 10 passes through the cover plate 8 and extends to the lower surface of the cover plate 8. A valve is provided on the liquid injection pipe 10. A transparent plate 7 is provided on the side surface of the box body 6.

[0023] Specifically, fixing block 19 and fixing block 219 are fixedly connected by bolts, so that the box body 6 and the cover plate 8, and the shell 1 and the shell 2 can be fastened. After the piston plate 17 is placed, pigment water can be injected into the box body 6 through the injection pipe 10, so as to facilitate observation. The valve on the injection pipe 10 prevents the pigment water from flowing out of the injection pipe 10 when it is pushed. The transparent plate 7 makes it easy to observe the position of the piston plate 17.

[0024] Working principle: During use, if a leak occurs in valve body 13 or at the connection between valve body 13 and gas pipe 3, the leaked gas will first fill the area between housing 1 and housing 2 and gas pipe 3. Since the through groove 14 is connected to this area, the gas will enter the through groove 14 and then enter the housing 6 through the connecting pipe between housing 6 and through groove 14. This will push the piston plate 17, causing it to rise, thereby pushing the pigment water inside housing 6 and squeezing it into the transparent hollow column 11, making it easier for people to detect that the gas has leaked.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
