Problems solved by technology

At present, the existing check valves on the market basically cannot realize the function of adjusting the air volume. For the situation where the air volume needs to be adjusted, it is generally realized by adjusting the air valve, which has a complex structure and high cost.
At the same time, the existing check air valve is generally only suitable for one installation method, horizontal installation or vertical installation
In addition, in the existing check valve, the stability of the vane becomes poor after long-term use, and it is easy to deform

Embodiment 1

[0037] This embodiment provides an adjustable non-return air valve 100, the number of adjusting blades in the adjustable non-return air valve 100 is two, that is, the adjustable non-return air valve 100 is a double-blade adjustable non-return air valve 100 .

[0038] Specifically, please also refer to figure 1 , figure 2 , image 3 and Figure 4 , the adjustable non-return air valve 100 includes a valve body 1000 through which both ends pass through. In this embodiment, the material of the valve body 1000 is set according to the requirements of the actual application. As an exemplary material, the material of the valve body 1000 in this embodiment is metal, such as aluminum alloy, ordinary carbon steel, stainless steel, etc. . When the material of the valve body 1000 is ordinary carbon steel, it is preferable to provide an anti-corrosion layer on its surface. In this embodiment, the material of the valve body 1000 is set according to the requirements of the actual applica...

Embodiment 2

[0060] This embodiment provides an adjustable non-return air valve 100 , the adjustable non-return air valve 100 has one adjusting vane, that is, the adjustable non-return air valve 100 is a single-blade adjustable non-return air valve 100 .

[0061] Specifically, please also refer to figure 1 , figure 2 , image 3 and Figure 4 , the adjustable non-return air valve 100 includes a valve body 1000 through which both ends pass through.

Abstract

The invention provides an adjustable non-return air valve. A first air quantity adjustment assembly is arranged in a valve body, the first air quantity adjustment assembly comprises a first rotary shaft and a first adjustment blade, a first support assembly is fixed to the first rotary shaft, and the first support assembly is abutted against the leeward surface of the first adjustment blade; and an angle adjustment mechanism is arranged outside the valve body, the angle adjustment mechanism comprises a rotary sheet and a fixed frame, one end of the rotary sheet is fixedly connected with a first rotary shaft, an arc-shaped groove taking the first rotary shaft as a circle centre is formed in the fixed frame, a bolt is arranged at the other end of the rotary sheet, the bolt is arranged in the arc-shaped groove, a fastening assembly is connected to the bolt in a sleeving manner, the bolt keeps fixed in the arc-shaped groove when the fastening assembly is locked, and the bolt is capable of moving in the arc-shaped groove and then sequentially driving the rotary sheet, the first rotary shaft and the first adjustment blade to rotate when the fastening assembly is unlocked. The adjustable non-return air valve has an air quantity adjustment function.

Description

technical field [0001] The invention relates to the technical field of air volume adjustment, in particular to an adjustable non-return air valve. Background technique [0002] In piping systems such as ventilation and smoke exhaust, in order to prevent backflow, it is necessary to install a check valve in the piping system. The existing non-return air valves on the market basically cannot realize the function of adjusting the air volume. For the situation where the air volume needs to be adjusted, the air volume adjustment valve is generally used to realize the function, which has a complex structure and high cost. At the same time, the existing non-return air valve is generally only suitable for one installation method, horizontal installation or vertical installation. In addition, in the existing check valve, the stability of the vane becomes poor after long-term use, and it is easy to deform. Contents of the invention [0003] In order to overcome the deficiencies of...
