[0016] The embodiment of the present application discloses a safety valve. Figure 1 、 Figure 2 , including a three-way pipe 1, which is connected to a safety valve 2, an automatic exhaust valve 3, a ball valve 4 and a pressure gauge 5. The safety valve 2, the automatic exhaust valve 3, the ball valve 4 and the pressure gauge 5 are common workpieces on the market. When the pressure in the three-way pipe 1 reaches a certain level, the safety valve 2 automatically connects with the outside world to discharge the medium in the three-way pipe 1, thereby ensuring the safety of the three-way pipe 1 and the pipeline or equipment connected to the three-way pipe 1. The automatic exhaust valve 3 can be used to discharge the gas in the pipeline or equipment connected to the three-way pipe 1. The ball valve 4 is used to facilitate the control of the opening and closing of the three-way pipe 1 and the pipeline or equipment. The pressure gauge 5 is used to facilitate the monitoring and display of the pressure in the three-way pipe 1. Compared with the safety valve with only the safety valve 2 in the prior art, the automatic exhaust valve 3, the ball valve 4 and the pressure gauge 5 have more functions. The safety valve 2, the automatic exhaust valve 3 and the ball valve 4 are respectively connected to one section of the tee pipe 1, and the pressure gauge 5 is connected to the connecting point of the three sections of the tee pipe 1, so that the safety valve 2, the automatic exhaust valve 3, the ball valve 4 and the pressure gauge 5 do not affect each other.
[0017] Reference Figure 1 、 Figure 2 、 Figure 3 The end of a section of the tee pipe 1 where the ball valve 4 is located is movably connected to a movable interface 6, which facilitates connecting the tee pipe 1 to a pipeline or equipment through the movable interface 6 and communicating with each other. A limit ring 7 extends from the end of the section of the tee pipe 1 where the ball valve 4 is located. The movable interface 6 is sleeved on the end of the tee pipe 1, and one end thereof abuts against the limit ring 7, so that the limit ring 7 limits the movable interface 6 and prevents the movable interface 6 from detaching from the tee pipe 1. A first snap ring groove 8 is formed on the outer wall of the tee pipe 1 at the limit ring 7, and a second snap ring groove 9 is formed on the inner wall of the movable interface 6. A sealing ring 10 is fixedly secured in the first snap ring groove 8 and the second snap ring groove 9, so that the sealing ring 10 is snapped and limited by the first snap ring groove 8 and the second snap ring groove 9, preventing the sealing ring 10 from detaching from the outer wall of the tee pipe 1 and the movable interface 6, thereby using the sealing ring 10 to block the gap between the outer wall of the tee pipe 1 and the movable interface 6.
[0018] Reference Figure 1 、 Figure 2 、 Figure 3 The inner wall of the movable interface 6 is provided with several internal threads of different diameters, enabling connection of a variety of pipes of different diameters through the movable interface 6. The internal threads, from the outside in, include a first internally threaded hole 11, a second internally threaded hole 12, and a third internally threaded hole 13. The first internally threaded hole 11, the second internally threaded hole 12, and the third internally threaded hole 13 are arranged from large to small, allowing connection of pipes of different diameters through the first internally threaded hole 11, the second internally threaded hole 12, and the third internally threaded hole 13, respectively, making the entire safety valve more flexible to use. The internal threads include not only the first internally threaded hole 11, the second internally threaded hole 12, and the third internally threaded hole 13, but can also have more threads to facilitate connection of pipes of more different diameters.
[0019] Reference Figure 2 、 Figure 3 A supporting spring and a sealing gasket 14 are provided in the movable interface 6. The two ends of the supporting spring respectively conflict with the end of the tee pipe 1 and the sealing gasket 14. The end of the supporting spring extends into the first internal threaded hole 11 in a natural state, so that the gap between the pipe and the tee pipe 1 is sealed by the sealing gasket 14. At the same time, the supporting spring is used to provide elastic force for the sealing gasket 14, so that the sealing gasket 14 can better seal the gap between the pipe and the tee pipe 1. The size of the sealing gasket 14 can be selected according to the diameter of the pipe to be connected, so that the sealing gasket can better match the pipe, thereby achieving better sealing of the gap between the pipe and the movable interface 6.
[0020] Unless otherwise specified, the device components involved in the above embodiments are all conventional device components, and the structural settings, working modes or control modes involved are all conventional settings, working modes or control modes in the art unless otherwise specified.
[0021] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
