DETAILED DESCRIPTION

[0024] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] The ventilation coupling valve according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0026] like Figure 5 and Figure 6 As shown, the ventilation coupling valve of an embodiment of the present invention comprises a coupling valve body, an observation structure 600 and a float 700.

[0027] Among them, such as Figure 2 and Figure 3 As shown, a protrusion 101 is integrally formed on the outer wall of the coupling valve body, and two through holes 102 penetrating the coupling valve body are opened on the protrusion 101.

[0028] It should be noted that, by providing the integrally formed raised portion 101 , the strength of the raised portion 101 is higher compared to welding or other methods.

[0029] like Figure 4 As shown, the observation structure 600 includes a mounting base 610 and a transparent arc-shaped cavity 620. The transparent arc-shaped cavity 620 is connected to the mounting base 610 and is integrally formed. The mounting base 610 is detachably mounted on the raised portion 101, wherein the two through holes 102 are respectively connected to the transparent arc-shaped cavity 620.

[0030] The float 700 is disposed in the transparent arc-shaped cavity 620 , wherein the aperture of the through hole 102 is smaller than the diameter of the float 700 .

[0031] As a possible scenario, the transparent arc cavity 620 is a hemispherical structure with a hollow interior, and the transparent arc cavity 620 can be made of transparent glass or transparent plastic to ensure that relevant staff can observe the movement of the float 700 through the transparent arc cavity 620.

[0032] It should be noted that the float 700 is made of lightweight materials, including but not limited to polyethylene, polypropylene or foam materials, to ensure the buoyancy of the float 700 in the liquid, and the float 700 is sprayed with a striking color, so that when the float 700 floats, relevant personnel can more clearly observe the amplitude of the movement of the float 700.

[0033] To clearly illustrate the above embodiment, in one embodiment of the present invention, Figures 1 to 3 As shown, the coupling valve body includes a valve body 100, a valve core (not shown in the figure), an exhaust valve (not shown in the figure) and a chain valve (not shown in the figure).

[0034] The valve body 100 serves as a basic frame for accommodating internal components and providing connection interfaces with other pipelines or equipment.

[0035] The valve core is arranged in the valve body 100 to control the opening and closing of the gas or liquid. The valve body 100 is connected to an exhaust valve interface 200, and the exhaust valve is arranged in the exhaust valve interface 200. A chain valve seat 300 is provided on the outer wall of the valve body 100, and the chain valve is arranged on the chain valve seat 300 to control the opening and closing of the exhaust valve.

[0036] It should be noted that controlling the opening and closing of the exhaust valve by the interlocking valve can ensure the stable use of the exhaust valve under high-pressure environment.

[0037] In addition, a communication port 400 is provided on the top of the valve body 100 , a flange 500 is provided on the bottom of the valve body 100 , and an observation structure 600 is provided on the valve body 100 , and the raised portion 101 is integrally formed with the valve body 100 .

[0038] Specifically, when using the ventilation coupling valve of the present invention, the connecting ports 400 at the upper and lower ends of the valve body 100 are connected to the flange 500 and the external pipeline, and the flow of liquid in the valve body 100 is controlled by the valve core, and the exhaust valve is controlled to be closed at a preset pressure through the interlocking valve.

[0039] When the liquid flows in the valve body 100, the liquid flows from the through hole 102 into the transparent arc-shaped cavity 620. As the flow rate of the liquid changes, the float 700 moves and changes in the transparent arc-shaped cavity 620. Relevant staff can visually observe the changes in the liquid flow in the valve body 100 through the changing amplitude and frequency of the float 700. The entire observation process is clearer and more intuitive, and the entire observation structure 600 is simpler and less costly.

[0040] In one embodiment of the present invention, threaded holes 103 are provided at the four corners of the protrusion 101, and mounting holes 601 are provided at the four corners of the mounting seat 610. The four threaded holes 103 correspond to the four mounting holes 601 one by one and are respectively locked by bolts.

[0041] It should be noted that when using bolts to lock the mounting seat 610 on the raised portion 101, an elastic gasket can be provided on the bolt. As the bolt passes through the mounting hole 601 and is threaded into the threaded hole 103, the elastic gasket is compressed to prevent vibration caused by long-term flow of liquid, which may cause the bolt to loosen.

[0042] In order to further improve the sealing performance of the connection between the mounting seat 610 and the raised portion 101 , an elastic sealing ring is provided at the connection between the raised portion 101 and the mounting seat 610 .

[0043] It should be noted that the elastic sealing ring is used to seal the connection between the mounting seat 610 and the raised portion 101. The mounting seat 610 is squeezed by bolts, causing the elastic sealing ring to deform and fill the connection between the mounting seat 610 and the raised portion 101.

[0044] In one embodiment of the present invention, scale lines are provided on the inner wall of the transparent arc-shaped cavity 620, and the scale lines are used to indicate the position of the float 700 in the transparent arc-shaped cavity 620. Relevant staff can observe the amplitude of the movement of the float 700 through the position of the scale lines.

[0045] As another possible situation, a plurality of concentric circles are provided on the inner wall of the transparent arc-shaped cavity 620 and are marked with scales, and relevant staff can observe the movement amplitude of the float 700 through the concentric circles.

[0046] In one embodiment of the present invention, the mounting seat 610 is a rectangular plate, and the raised portion 101 matches the mounting seat 610 .

[0047] It should be noted that the mounting seat 610 and the raised portion 101 may also be in other shapes such as an ellipse or a circle.

[0048] In summary, according to the ventilation coupling valve of the embodiment of the present invention, by setting a transparent arc-shaped cavity 620 on the outer wall of the valve body 100 and setting a float 700 in the transparent arc-shaped cavity 620, the operator can intuitively observe the liquid level or gas state inside the valve body 100. By integrally forming the protrusion 101 and the valve body 100, the installation strength of the connection can be enhanced and the service life can be improved. The overall structure is simple and the cost is low.
