[0023] 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.

[0024] Embodiment 1

[0025] Combined with Figure 1 and attached Figure 3 A wind valve that is easy to assemble comprises a valve body 1, a valve plate 5 is arranged in the valve body 1, and a rotating shaft 4 that is easy to disassemble and assemble is inserted in the valve body 1.

[0026] Through the above structure, the rotating shaft 4 drives the valve plate 5 to rotate, which is convenient for controlling the air volume, and the rotating shaft 4 is easy to disassemble and assemble, and is convenient to use.

[0027] Combined with Figure 2 and attached Figure 4 An auxiliary shaft 8 rotatably connected to the valve body 1 is inserted on one side of the valve body 1, and a fixed block 9 is provided at one end of the auxiliary shaft 8 extending into the valve body 1. One end of the rotating shaft 4 extends into the fixed block 9, and a fixing structure is provided between the rotating shaft 4 and the fixed block 9.

[0028] Through the above structure, the auxiliary shaft 8 can be used to realize the rotation connection between the fixed block 9 and the valve body 1, and one end of the rotating shaft 4 extends into the fixed block 9 and is fixed as a whole, which is convenient for adjusting the valve plate 5.

[0029] Combined with Figure 4 and attached Figure 6 The fixing structure includes limiting holes 10 arranged at the top and bottom ends of the fixing block 9, grooves 11 are provided at both ends of one side of the rotating shaft 4, springs 12 are provided in the grooves 11, and limiting columns 13 used in conjunction with the limiting holes 10 are provided on one side of the spring 12.

[0030] Through the above structure, the rotating shaft 4 slowly approaches the fixed block 9, pinches the limit columns 13 on both sides, and squeezes the spring 12. When the rotating shaft 4 enters the fixed block 9, the limit column 13 is released, and the spring 12 rebounds with elastic force, driving the limit column 13 to enter the limit hole 10, thereby fixing the rotating shaft 4 and the fixed block 9 together and making the whole stable.

[0031] Embodiment 2

[0032] Combined with Figure 5 At least one fixing hoop 6 is provided on one side of the valve plate 5 . The fixing hoop 6 is clamped on the rotating shaft 4 and fixed integrally by fastening bolts 7 and nuts. Sealing rings are provided around the valve plate 5 .

[0033] Through the above structure, the valve plate 5 is directly fixed on the rotating shaft 4 by means of the fixing hoop 6, the fastening bolts 7 and the nuts, which is convenient for assembly. In addition, sealing rings are arranged around the valve plate 5. When the valve plate 5 is in a vertical state, the overall sealing is good.

[0034] Combined with Figure 1 and attached Figure 3 A locking structure is provided between the rotating shaft 4 and the valve body 1, and a turning handle 14 is provided at one end of the rotating shaft 4 extending outside the valve body 1. The locking structure includes a section of thread 15 arranged on the rotating shaft 4 and located outside the valve body 1, and a knob 16 is sleeved on the rotating shaft 4 and used to cooperate with the thread 15 and is threadedly connected to the rotating shaft 4.

[0035] Through the above structure, the knob 16 is continuously rotated to slowly approach one side of the valve body 1 so that it is tightly pressed against the valve body 1, thereby locking the rotating shaft 4 to prevent it from rotating at will and affecting the use.

[0036] Combined with Figure 1 A connecting plate 2 is disposed on both sides of the valve body 1, and a plurality of connecting holes 3 are disposed on the connecting plate 2.

[0037] Through the above structure, the valve body 1 and the external pipeline can be conveniently connected by using the connecting plate 2 and the connecting hole 3.

[0038] When the utility model is implemented:

[0039] The valve body 1 and the external pipeline can be connected by using the connecting plate 2 and the connecting hole 3, which is convenient for installation.

[0040] Insert one end of the rotating shaft 4 into the valve body 1, slowly move the rotating shaft 4 to make it close to the fixed block 9, pinch the limit columns 13 on both sides, and squeeze the spring 12. When the rotating shaft 4 enters the fixed block 9, release the limit column 13, and the spring 12 rebounds, driving the limit column 13 to enter the limit hole 10, fixing the rotating shaft 4 and the fixed block 9 together, and the whole is stable.

[0041] The valve plate 5 is directly fixed on the rotating shaft 4 by means of a fixing hoop 6, a fastening bolt 7 and a nut, so that the assembly is convenient. Moreover, sealing rings are arranged around the valve plate 5. When the valve plate 5 is in a vertical state, the overall sealing performance is good.

[0042] Turning the handle 14 drives the rotating shaft 4 to rotate, and the valve plate 5 rotates accordingly. The inclination angle of the valve plate 5 can be flexibly adjusted as needed. When the valve plate 5 reaches the target position, the knob 16 is turned continuously to make it slowly approach one side of the valve body 1 so that it is tightly against the valve body 1, thereby locking the rotating shaft 4 to prevent it from rotating at will and affecting its use.

[0043] Through the simple connection method and quick installation design, workers can quickly complete the assembly and installation of the air valve, thereby improving the installation efficiency of the entire project and facilitating subsequent maintenance or replacement of parts.
