After flowing through the joint body 1, the water flows to the pressure sensor 2.
As shown in fig. 1 and 2, the joint body 1 includes a tubular main body 3, and a partition plate is provided at a central position thereof so as to partition the main body 3 into left and right cavities. Liner tubes are arranged at two ends of the partition plate, first flow passages 5 penetrating axially are formed in the liner tubes, and cavities at two sides of the main body 3 are communicated through the first flow passages 5.
Both ends of the main body 3 are provided with internal threads, and are respectively in threaded connection with a first joint 4 and a second joint 12.
The first joint 4 is provided with a second flow passage 6 penetrating axially at the center, and a space is provided between the inner end of the first joint 4 and the partition plate, so that a third flow passage 7 is formed between the first joint 4 and the main body 3. There is a space between the first joint 4 and the liner tube such that the third flow passage 7 communicates with the first flow passage 5.
A fourth flow passage 13 penetrating axially is arranged at the center of the second joint 12, and a space is arranged between the inner end of the second joint 12 and the partition plate, so that a fifth flow passage 14 is formed between the second joint 12 and the main body 3. There is a spacing between the second fitting 12 and the liner tube such that the fifth flow passage 14 communicates with the first flow passage 5.
The water flow passes through the second flow passage 6, the third flow passage 7, the first flow passage 5, the fifth flow passage 14 and the fourth flow passage 13 in this order and then flows to the area of the pressure sensor 2. The second flow passage 6, the third flow passage 7, the first flow passage 5, the fifth flow passage 14 and the fourth flow passage 13 form two symmetrically arranged S-shaped structures, so that the flow speed of water flow is relieved, and the high pressure generated by the water hammer effect is reduced.
The first connector 4 is fixed with a first deflector 8 and a second deflector 10 which are arranged at intervals in a sleeving manner. As shown in fig. 3 and 4, the first deflector 8 is provided with two symmetrically arranged hole groups, each hole group being composed of two symmetrically arranged first deflector holes 9; the first deflector hole 9 is formed in a wedge shape, and an outlet thereof is a necking end. As shown in fig. 5 and 6, the second deflector 10 is provided with two symmetrically arranged hole groups, each hole group being composed of two symmetrically arranged second deflector holes 11; the second diversion holes 11 are wedge-shaped, and the outlets are necking ends.

The first and second deflectors 8 and 10 block the third flow passage 7 so that water flows only from the first and second deflector holes 9 and 11. The third and fourth deflectors 15 and 17 block the fifth flow passage 14 so that water flows only from the third and fourth deflector holes 16 and 18. When water flows out from the first diversion holes 9 and the second diversion holes 11, two opposite flushing occurs in sequence; two opposite-flushing occurs in sequence when the water flows out of the third diversion hole 16 and the fourth diversion hole 18; therefore, the water flow consumes inertial potential energy generated by the impact of the water hammer in the impact process, the impact pressure is higher, the impact is more intense, the consumed energy is larger, and the instant high pressure generated by the water hammer effect is counteracted.
In summary, under the combined influence of the curved waterway and the water flow opposite, the water flow pressure flowing out of the joint body 1 can be restored to the normal working pressure of the system, so that the pressure sensor 2 is effectively protected.
