Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Examples, such as Figure 1-4 As shown, the utility model provides a reverse-thread fixed connection type solenoid valve, including: a pipe main body 1, and also including: a water inlet 8, which is arranged at one end of the pipe main body 1, and one end of the pipe main body 1 is provided with a reverse-thread external thread 14, and the inside of the water inlet 8 is slidably connected with a flexible fixing sleeve 11, and the inner wall of the flexible fixing sleeve 11 close to the outer surface of the pipe main body 1 is provided with a reverse-thread internal thread 12, the flexible fixing sleeve 11 is threadedly connected to the pipe main body 1, and the outer surface of the flexible fixing sleeve 11 is movably connected with a flexible joint 3.

[0024] Further, such as Figure 1-4 As shown, a limiting step 10 is provided on the inner wall of the flexible joint 3 near the pipe body 1, and a limiting step 2 13 is provided on the outer surface of the flexible joint fixing sleeve 11. The limiting step 2 13 cooperates with the limiting step 10. By cooperating with the limiting step 10 and the limiting step 2 13, the flexible joint 3 is axially limited, and the flexible joint 3 can rotate.

[0025] Further, such as Figure 1-4 As shown, the other end of the pipe body 1 is provided with a water outlet 6, and the other end of the pipe body 1 is provided with a reverse external thread 5. Through the setting of the reverse external thread 5, it is convenient to connect and fix the water outlet 6 of the pipe body 1 with the external pipe in a threaded connection manner.

[0026] Further, such as Figure 1-4 As shown, the inner wall of the flexible joint 3 is provided with a reverse internal thread 9, and the outer surface of the flexible joint 3 is provided with a plurality of anti-slip grooves in a circumferential array. The setting of the reverse internal thread 9 facilitates the connection and fixation of the flexible joint 3 with the external pipe in a threaded connection manner, and the setting of the anti-slip groove facilitates the rotation of the flexible joint 3.

[0027] Further, such as Figure 1-4 As shown, the outer surface of the pipe body 1 is fixedly connected with a valve body 2, and the flow and stop of water can be controlled by the setting of the valve body 2.

[0028] Further, such as Figure 1-4 As shown, a turbine assembly 7 is fixedly connected to the interior of the pipe body 1 at the water outlet 6, and a Hall sensor assembly 4 is fixedly connected to the outer surface of the pipe body 1. The arrangement of the turbine assembly 7 and the Hall sensor assembly 4 facilitates the detection of the flow of the fluid medium inside the pipe body 1.

[0030] Working principle: When in use, first insert the flexible joint fixing sleeve 11 into the interior of the flexible joint 3, and then insert the hexagonal wrench into the hexagonal groove of the flexible joint fixing sleeve 11 to limit the flexible joint fixing sleeve 11. At this time, the flexible joint fixing sleeve 11 can be inserted into the interior of the water inlet 8, and with the cooperation of the reverse internal thread 12 and the reverse external thread 14, the pipe body 1 is rotated, so that the water inlet 8 and the flexible joint fixing sleeve 11 are connected and fixed in a threaded connection manner. By cooperating with the limiting step 10 and the limiting step 2 13, the flexible joint 3 is axially limited. At this time, the flexible joint 3 can be rotated, and with the cooperation of the reverse internal thread 9, it can be connected and fixed with the external pipe in a threaded connection manner. Similarly, with the cooperation of the reverse external thread 5, the pipe body 1 can be connected and fixed with the external pipe in a threaded connection manner. In this way, with the cooperation of the flexible joint 3 that can be rotated, damage to the external pipe when the external pipe is twisted can be avoided, thereby preventing leakage, thereby improving the use effect of the solenoid valve.
