[0019] Example
[0020] like Figure 1-3 As shown, a new type of stop valve is mainly composed of a first pipeline 1, a second pipeline 2, a ball 3 and a telescopic adjustment component. In order to solve the problem of large difference in liquid pressure between the main pipeline and the branch pipeline, a stop valve capable of adapting to the pressure regulation of the entire pipeline is designed, wherein the telescopic adjustment component is arranged in the first pipeline 1 and the second pipeline 2 for pressure regulation, the second pipeline 2 is detachably connected to the lower end of the first pipeline 1, the ball 3 is placed in the second pipeline 2 and can move up and down, and the lower end of the second pipeline 2 is sealed.
[0021] Two bosses 11 are integrally formed at the lower end of the inner wall of the first pipe 1. The two bosses 11 are arranged opposite to each other. The telescopic adjustment component is arranged at the lower end of the boss 11. The telescopic adjustment component includes a bolt member 4 and a spring 41. One end of the spring 41 is against the boss 11 through the bolt member 4, and the other end is against the ball 4. The bolt member 4 is arranged in a cylindrical structure. The upper end of the spring 41 is fixedly connected to the bottom end of the bolt member 4, and an annular groove 42 is provided at the top of the bolt member 4. The side of the bolt member 4 located inside the annular groove 42 is provided with an external thread. At the same time, a thread is provided at the bottom end of the boss 11. An annular through groove 12 and an internal threaded hole 13 are provided, wherein the annular through groove 12 cooperates with the annular groove 42, and the internal threaded hole 13 corresponds to the external thread 1; when in use, the spring 41 is installed under the boss 11 by rotating the bolt member 4, and when liquid enters, the ball 3 rises under the push of the liquid, thereby compressing the spring 41, and the liquid pressure is balanced by the rebound force of the spring 41. According to the liquid pressure difference in the pipeline, the distance between the spring 41 and the ball 3 can be adjusted, and the compression degree of the spring 41 can be adjusted to reduce the pressure fluctuation amplitude.
[0022] An upper connecting seat 5 is fixedly installed on the first pipe 1 located below the boss 11, and a lower connecting seat 6 is fixedly installed on the top of the second pipe 2, and a second internal threaded hole 51 is provided at the bottom end of the upper connecting seat 5, and a second external thread matched with the second internal threaded hole 51 is provided on the side of the lower connecting seat 6, and at the same time, a through hole matched with the inner diameter of the second pipe 1 is provided at the upper end of the upper connecting seat 5, and the through hole is connected with the second internal threaded hole 51, and a through hole matched with the second pipe 1 is provided on the lower connecting seat 6; an upper sealing layer 14 is bonded to the bottom end of the upper connecting seat 5 located outside the second internal threaded hole 51, and a lower sealing layer 21 is bonded to the top of the second pipe 2 located outside the lower connecting seat 6, and the lower end surface of the upper sealing layer 14 is meshed with the upper end surface of the lower sealing layer 21.
[0023] Working principle: When in use, first rotate the second pipe 2 to remove the lower connecting seat 6, and then rotate the bolt 4 to adjust the distance between the spring 41 and the ball 3 according to the internal pressure of different pipelines. The ball 3 compresses the spring 41 to fine-tune the compression of the spring 41 to reduce the pressure fluctuation amplitude and stabilize the feeding and medicated bath treatment process; if the pressure difference of the liquid inside the pipeline is too large, the spring 41 at the lower end of the bolt 4 can also be replaced to further increase the compression force and balance the pressure.
