[0014] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation to the present invention. DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0016] like Figure 1-3 As shown, the pneumatic component structure of a pneumatic drain valve proposed by the utility model is arranged on the drain valve with a snap connection, and the drain valve is provided with a large float rod 2 and a connecting tube 1. The pneumatic component structure comprises a top tube bracket 9, a drain lifting rod, a top tube outer sleeve 6, a top tube core 5, a top tube inner sleeve 4, an air bag 3 and an air pipe joint 10. The top tube bracket 9 is snap-connected to the connecting tube 1, and the drain lifting rods are symmetrically arranged on both sides of the top tube bracket 9. The top tube outer sleeve 6 is clamped on the top tube bracket 9, the top tube core 5 is fixed on the top tube bracket 9 and penetrates the top tube bracket 9. The bottom of the air bag 3 is arranged on the top tube core 5, the top tube inner sleeve 4 is sleeved on the outside of the air bag 3, and the air pipe joint 10 is sleeved on the bottom of the top tube core 5. The drain lifting rod is provided with two groups, namely a small drainage lifting rod 7 and a large drainage lifting rod 8. The small drainage lifting rod 7 and the large drainage lifting rod 8 are movably connected relative to the top tube bracket 9, and the small drainage lifting rod 7 and the large drainage lifting rod 8 are respectively clamped on the large float rod 2.

[0017] During specific use, the air pipe joint 10 is connected to the pneumatic equipment. When the pneumatic equipment is running, air is taken in from the air pipe joint 10 into the air bag 3. The air bag 3 is deformed to lift up the inner sleeve 4 of the top tube together with the small drainage lifting rod 7 or the large drainage lifting rod 8, so that the large floating rod 2 can be lifted up, and the water flows out from the drainage hole and falls back under the action of gravity. The above is the use process of the entire improved pneumatic drain valve.

[0018] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
