[0002] A gas generator is a device that uses the heat energy generated by gas combustion to drive a generator to generate electricity. Such generators usually use natural gas, biogas, liquefied petroleum gas (LPG), coalbed methane, etc. as fuels. The gas generator converts the high-temperature and high-pressure gas generated by gas combustion into mechanical energy, and then converts the mechanical energy into electrical energy through the generator.

[0003] After retrieval, the existing Chinese patent publication number is: CN213982336U. When a gas generator set is in use, gas needs to be transported through a gas transmission pipeline to supply the normal operation of the gas generator set. The gas transmission pipeline is usually composed of several pipelines connected together, and the pipelines are connected by threads. The thread connection will cause wear of the threads during long-term use and frequent disassembly, reducing the sealing performance and increasing the risk of leakage. And if the thread connection is not tightened correctly during installation, leakage may occur, and the installation and disassembly efficiency of the thread connection is low.

[0004] In view of the above problems, for this reason, a leakage prevention device for a gas generator set is proposed. Content of the Utility Model

The first connector 2 is fixedly connected to one end of the first delivery pipe 1. Oil is delivered through the delivery pipe. A connecting pipe 204 is fixedly connected to the top end of the first delivery pipe 1. The outer wall of the first connector 2 is slidably connected with a disassembly shell 201. A spring groove 202 is opened on one side inside the disassembly shell 201. A first spring 203 is arranged inside the spring groove 202. A 205 is opened on the side of the disassembly shell 201 away from the spring groove 202. One side of the first connector 2 penetrates and is slidably connected with a sphere 206. Pull the disassembly shell 201 backward so that 205 reaches the position of the sphere 206. Then dock the first connector 2 with the second connector 208. During the docking process, the sphere 206 is lifted by the sleeve 209 and the first connector 2. Then the sleeve 209 is sleeved on the surface of the connecting pipe 204 for splicing. The anti-leakage installation component includes a second delivery pipe 207 and a second connector 208. The second delivery pipe 207 is arranged on one side of the first delivery pipe 1. A second connector 208 is sleeved outside the second delivery pipe 207. A sleeve 209 is fixedly connected to the side of the second delivery pipe 207 close to the first delivery pipe 1 and the sleeve 209 cooperates with the connecting pipe 204. When the sleeve 209 is sleeved on the connecting pipe 204, the connection is more sealed. A limit groove 210 is opened at the connection part of the sleeve 209 and the second delivery pipe 207 and the limit groove 210 cooperates with the sphere 206 so that the sphere 206 falls into the limit groove 210 for limiting.

[0024] Combined with Figure 3 and Figure 4 , a sealing gasket 3 is sleeved on the outer wall of the casing 209 to ensure the sealing performance of the connection.

An annular sleeve 6 is installed on the side of the second spring 5 away from the groove 4. The annular sleeve 6 cooperates with the sealing gasket 3. When the casing 209 moves towards the connecting pipe 204, the annular sleeve 6 compresses through the second spring 5 by the sealing gasket 3, so that the sealing gasket 3 is clamped into the groove 4 for sealing.

[0025] Working principle: When installing, pull the disassembly shell 201 backward so that 205 reaches the position of the sphere 206. Then dock the first connector 2 with the second connector 208. During the docking process, the sphere 206 is lifted by the casing 209 and the first connector 2. Then the casing 209 is sleeved on the surface of the connecting pipe 204 for splicing. At the same time, the sphere 206 falls into the limiting groove 210 for limiting. At the same time, when the casing 209 moves towards the connecting pipe 204, the annular sleeve 6 compresses through the second spring 5 by the sealing gasket 3, so that the sealing gasket 3 is clamped into the groove 4 for sealing, avoiding gas leakage and enabling quick splicing.
