[0012] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0013] 1. Due to the use of the air valve housing, valve plate, connecting rod, rotating device and protective assembly, when the valve plate in the inner cavity of the air valve housing needs to be opened and closed, the staff rotates the rotating rod in the rotating device. Since the second bevel gear on the rotating rod is meshed and connected with the first bevel gear on the connecting rod, when the rotating rod is rotated, the second bevel gear and the first bevel gear can be driven to rotate together. Since the first bevel gear is fixedly connected to the connecting rod and the valve plate is fixedly connected to the connecting rod, when the first bevel gear rotates, the valve plate can be driven to rotate in the inner cavity of the air valve housing, thereby controlling the angle of rotation of the valve plate in the inner cavity of the air valve housing and the opening and closing state of the valve plate in the inner cavity of the air valve housing. The entire operation process is simple and reliable, and is convenient for staff to operate. At the same time, the rotating device is operated only by manually rotating the rotating rod without the participation of a motor. Therefore, by comparison, the use cost of the air valve can be further reduced. Since the protective assembly is detachably installed at both ends of the valve plate, the two sets of protective assemblies can prevent the valve plate from being damaged during the opening and closing process, thereby playing a certain protective role for the valve plate.

[0014] 2. Due to the use of the connection handle, baffle plate and second fixing member, the two sets of baffle plates are fixedly connected by the connection handle, and the two sets of baffle plates are detachably fixedly installed at both ends of the valve plate by a plurality of sets of second fixing members, so it is convenient for the staff to hold the connection handle to disassemble and install the two sets of baffle plates. The baffle plates are installed at both ends of the valve plate, which can prevent the valve plate from being damaged after long-term opening and closing, and thus can play a good protective role on the valve plate itself.

[0015] 3. Due to the setting of the rotating handle, the rotating rod can be driven to rotate together by rotating the rotating handle, which makes it more convenient for the staff to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The embodiments of the present application provide an air valve that is easy to open and close, thereby solving the technical problem that the opening angle of the air valve disc in the prior art solutions is mostly controlled by motor drive. If the motor is damaged, the staff will not be able to open or close the air valve disc, which leads to an increase in the cost of using the air valve.

[0021] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] A damper that is easy to open and close, such as Figure 1 and Figure 2 As shown, it includes a damper housing 1, a valve plate 2 for closing the damper housing 1, a connecting rod 3 rotatably connected to the damper housing 1, a rotating device 4 for driving the connecting rod 3 to rotate, and a protective component 5 for covering the valve plate 2. The valve plate 2 is arranged on the connecting rod 3, and the valve plate 2 is located in the inner cavity of the damper housing 1. The rotating device 4 is arranged at the top of the damper housing 1, and the rotating device 4 is transmission-connected to the connecting rod 3. Protective components 5 are installed at both ends of the valve plate 2.

[0024] The rotating device 4 includes a supporting groove 41, a top cover 42 that is buckled at the opening of the supporting groove 41, a first fixing member 43 for fixing the top cover 42, a first bevel gear 44 arranged at the top end of the connecting rod 3, a second bevel gear 45 for driving the first bevel gear 44 to rotate, a rotating rod 46 connected to the second bevel gear 45, and a supporting seat 47 for supporting the rotating rod 46. The supporting groove 41 is arranged at the top end of the air valve housing 1. The first fixing member 43 is connected to the top cover 42 and the supporting groove 41. The first bevel gear 44 is meshedly connected to the second bevel gear 45. Two groups of supporting seats 47 that are symmetrically placed are arranged in the inner cavity of the supporting groove 41. The rotating rod 46 is rotatably connected to the two groups of supporting seats 47, and the two groups of supporting seats 47 are both arranged at the top end of the air valve housing 1.

[0025] The valve disc 2 is fixedly connected to the connecting rod 3, and the valve disc 2 is located in the inner cavity of the air valve housing 1. The rotating device 4 is fixedly connected to the top of the air valve housing 1, and the rotating device 4 is transmission-connected to the connecting rod 3. Both ends of the valve disc 2 are detachably fixedly installed with protective components 5. The first bevel gear 44 is fixedly connected to the top of the connecting rod 3. The second bevel gear 45 is fixedly connected to the rotating rod 46. The support groove 41 is fixedly connected to the top of the air valve housing 1. The first fixing member 43 is preferably a bolt. A plurality of groups of first fixing members 43 arranged in a linear array are provided at both ends of the top of the top cover 42. Each group of first fixing members 43 passes through the top cover 42 and is threadedly connected to the support groove 41. The rotating rod 46 is rotationally connected to two groups of support seats 47, and the rotating rod 46 is clamped on the two groups of support seats 47. Both groups of support seats 47 are fixedly connected to the top of the air valve housing 1.

[0026] Due to the arrangement of the air valve housing 1, the valve plate 2, the connecting rod 3, the rotating device 4 and the protective assembly 5, when the valve plate 2 in the inner cavity of the air valve housing 1 needs to be opened and closed, the staff rotates the rotating rod 46 in the rotating device 4. Since the second bevel gear 45 on the rotating rod 46 is meshed and connected with the first bevel gear 44 on the connecting rod 3, when the rotating rod 46 is rotated, the second bevel gear 45 and the first bevel gear 44 can be driven to rotate together. Since the first bevel gear 44 is fixedly connected to the connecting rod 3 and the valve plate 2 is fixedly connected to the connecting rod 3, when the first bevel gear 44 rotates, the valve plate 2 can be driven to rotate in the inner cavity of the air valve housing 1, thereby controlling the rotation angle of the valve plate 2 in the inner cavity of the air valve housing 1 and controlling the opening and closing state of the valve plate 2 in the inner cavity of the air valve housing 1. The whole operation process is simple and reliable, and is convenient for the staff to operate. At the same time, the rotating device 4 is operated only by manually rotating the rotating rod 46 without the participation of the motor, so by comparison, the use cost of the air valve can be further reduced. Since the protective components 5 are detachably installed at both ends of the valve plate 2 , the two sets of protective components 5 can prevent the valve plate 2 from being damaged during the opening and closing process, thereby playing a certain protective role for the valve plate 2 .

[0027] like Figure 3 As shown, the protection assembly 5 includes a connecting handle 51, a baffle 52 for covering the valve plate 2, and a second fixing member 53 for fixing the baffle 52. Baffles 52 are provided at both ends of the connecting handle 51. A plurality of groups of second fixing members 53 arranged in an arc array are provided on both groups of baffles 52. Each group of second fixing members 53 is connected to the baffle 52 and the valve plate 2. The baffle 52 is a semicircular structure.

[0028] Both ends of the connecting handle 51 are fixedly connected with baffles 52, and the two groups of baffles 52 are symmetrically arranged with the connecting handle 51. Both groups of baffles 52 are provided with a plurality of groups of second baffles arranged in an arc array and threadedly connected to the valve plate 2.

[0029] Due to the arrangement of the connecting handle 51, the baffle 52 and the second fixing member 53, the two groups of baffles 52 are fixedly connected by the connecting handle 51, and the two groups of baffles 52 are detachably fixedly installed at both ends of the valve plate 2 by a plurality of groups of second fixing members 53, so it is convenient for the staff to hold the connecting handle 51 to disassemble and install the two groups of baffles 52. The baffles 52 are installed at both ends of the valve plate 2, which can prevent the valve plate 2 from being damaged after long-term opening and closing, and thus can play a good protective role on the valve plate 2 itself.

[0030] like Figure 2 As shown, the rotating device 4 also includes a rotating handle 48. The rotating handle 48 is arranged at one end of the rotating rod 46.

[0031] The rotating handle 48 is fixedly connected to one end of the rotating rod 46 .
