Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1-3, an overflow valve protection device that sealing performance is good, including overflow valve body 3, the inner wall welding of 3 import pipes of overflow valve body has into pipe 7, the outer wall welding that overflow valve body 3 is close to the bottom has the shell 5 of no end, the inner wall of shell 5 has inlayed rubber packing ring 4, the lateral wall welding that advances pipe 7 has to support pipe 6, support the arc inside wall of pipe 6 and the outer wall threaded connection of 3 import pipes of overflow valve body, support the arc outside wall of pipe 6 and the inside wall threaded connection of shell 5, so the leakproofness of this department is better, support the top of pipe 6 and rubber packing ring 4 tightly, can further improve the leakproofness of whole device, one side outer wall of overflow valve body 3 is equipped with alarm mechanism.

The utility model discloses in, the inner wall welding of 3 exit ends of overflow valve body has connecting pipe 2, and the inner wall screw thread of connecting pipe 2 is pegged graft and is had pressure sensor 1.

Wherein, alarm mechanism includes four horizontal poles 8, and the one end of horizontal pole 8 all welds with the lateral wall of overflow valve body 3, and the one end welding that overflow valve body 3 was kept away from to four horizontal poles 8 has same casing 11, and the inner wall of casing 11 has the treater through the bolt fastening, and one side outer wall of casing 11 is opened there are two spliced eyes, has warning light 9 and switch 10 through the bolt fastening respectively in the spliced eye.
