Description

Technical Field

[0001] The utility model relates to the technical field of exhaust valves, in particular to a three-way exhaust valve with three functions. Background Art

[0002] The exhaust valve functions properly by combining the functions of intake and exhaust.

[0003] When the water supply to the pipeline needs to be stopped, due to the large diameter of the pipe, water will flow from the high point to the low point. At this time, a vacuum area will be formed at the highest point of the pipeline. In order to avoid the pipeline being sucked flat due to the vacuum, an exhaust valve will be installed on the pipeline to input air into the pipeline. However, the air intake of the traditional exhaust valve is fixed and cannot be adjusted according to the pressure in the pipe. As a result, the air intake cannot meet the normal air intake requirements of the pipeline, and the vacuum in the pipeline will suck the pipeline flat. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figure 1-3 The three-way three-function exhaust valve shown in the figure comprises a valve body 1, a second connecting pipe 5 is arranged on one side of the valve body 1, a second sub-valve 6 is arranged on the top of the second connecting pipe 5, a second exhaust assembly 7 is arranged inside the second sub-valve 6, an exhaust structure is arranged on the other side of the valve body 1, a valve cover 106 is arranged on the top of the valve body 1, an air intake valve plate 101 is arranged on the bottom of the valve cover 106, a moving rod 103 is arranged on the top of the air intake valve plate 101, and a threaded sleeve in the middle of the moving rod 103 is arranged. An adjusting nut 104 is provided, a spring 105 is provided on the side of the adjusting nut 104 opposite to the valve cover 106, a sealing rubber 102 is fixedly connected to the bottom of the valve cover 106, a moving rod 103 is inserted and connected in the middle of the valve cover 106, and the moving rod 103 is inserted and connected in the middle of the spring 105, an insect-proof net 109 is provided on the top of the valve cover 106, a rain cover 107 is provided on the top of the insect-proof net 109, and hanging rings 108 are symmetrically provided on both sides of the rain cover 107.

[0027] It should be noted that the valve cover 106 is fixedly connected to the top of the valve body 1 by a connecting flange and bolts. A hole for gas to pass through is opened on the valve cover 106. When gas needs to be input into the interior of the valve body 1, the gas enters the interior of the valve body 1 through the hole on the valve cover 106. The two ends of the spring 105 are respectively fixedly connected to the top of the valve cover 106 and the bottom of the adjusting nut 104. When in use, it is used to push the adjusting nut 104 to the side away from the valve cover 106, so that the moving rod 103 and the intake valve plate 101 are driven to move upward through the adjusting nut 104, so that the intake valve plate 101 and the sealing rubber 102 are fitted. The sealing rubber 102 is made of rubber material. When the rubber material is squeezed, it will deform, so that the gap at the connection between the intake valve plate 101 and the sealing rubber 102 is filled by deformation, thereby increasing the sealing performance of the connection between the intake valve plate 101 and the sealing rubber 102.

[0028] The movable rod 103 is inserted and connected to the middle part of the valve cover 106, and the moving direction of the movable rod 103 is limited by the valve cover 106, and the moving direction of the air intake valve plate 101 is limited by the movable rod 103 that limits the moving direction; the insect-proof net 109 is an annular net, through which the gas flows and the movement of mosquitoes is blocked through the mesh; the rain cover 107 is located on the top of the insect-proof net 109, and is used to prevent rainwater from entering the interior of the valve body 1 through the insect-proof net 109; the lifting ring 108 is used to pass the lifting rope, so as to facilitate the transportation of the exhaust valve.

[0029] Furthermore, a vacuum area is formed in the pipeline, and the vacuum gas suction in the pipeline drives the intake valve plate 101 to move and thus be opened. The spring is gradually compressed under pressure, and the elastic force is gradually increased. While air is being taken in, the spring 105 adjusts. The greater the vacuum suction, the more air is taken in. At the same time, the spring 105 increases in size, and air is automatically replenished according to the needs of the pipeline to ensure that no vacuum is formed in the pipeline, thereby protecting the safe operation of the pipeline.

[0030] Specifically, the exhaust structure includes a first connecting pipe 2 arranged on the other side of the valve body 1, a first sub-valve 3 is arranged on the top of the first connecting pipe 2, a first exhaust component 4 is arranged inside the first sub-valve 3, the first exhaust component 4 includes a first float 401 inserted and connected inside the first sub-valve 3, and a large number of exhaust sealing rings 402 are arranged on the inner wall of the top end of the first sub-valve 3.

[0031] It should be noted that, when in use, the first float 401 is driven to move up and down inside the first sub-valve 3 as the liquid enters and flows out of the first sub-valve 3. When the liquid enters the pipeline, the air in the pipeline is squeezed into the first sub-valve 3 as the liquid enters, and the gas moves the first float 401 located inside the first sub-valve 3 upward, thereby releasing the bottom of the first sub-valve 3, so that the first float 401 is located in the middle of the first sub-valve 3, and then the gas flows out through the hole at the top of the first sub-valve 3. When the liquid enters the first sub-valve 3 When the air in the air is filled with water, the first float 401 moves upward with the help of the liquid until it moves to the top of the first sub-valve 3, blocks the top hole of the first sub-valve 3, and fits with the large exhaust sealing ring 402. The first float 401 squeezes the large exhaust sealing ring 402, so that the large exhaust sealing ring 402 seals the connection between the first float 401 and the large exhaust sealing ring 402 through deformation to prevent liquid from flowing out. The large exhaust sealing ring 402 is made of rubber. A cover body with the same function as the rain cover 107 is provided on the top of the first sub-valve 3.

[0032] Specifically, the second exhaust assembly 7 includes a ball cage 701 arranged on the inner wall of the top end of the second sub-valve 6, the interior of the ball cage 701 is interlaced with a second float 702, the top of the second float 702 is fixedly connected with a trace exhaust sealing ring 705, the top of the ball cage 701 is interlaced with an exhaust hood 703, the top of the exhaust hood 703 is fixedly connected with a guide rod 704, and the guide rod 704 is interlaced and connected to the inner wall of the top end of the second sub-valve 6.

[0033] It should be noted that the surface of the ball cage 701 is provided with holes for the flow of gas and liquid, and holes for the circulation of gas are provided at the top of the second sub-valve 6 and in the middle of the exhaust cover 703. The ball cage 701 is used to limit the moving direction and moving distance of the second float 702, and the second float 702 can only move inside the ball cage 701; an insect-proof net 109 and a rain cover 107 are also provided on the top of the second sub-valve 6 to prevent rainwater and mosquitoes from entering the interior of the second sub-valve 6 from the top of the second sub-valve 6; when in use, when liquid flows out of the second sub-valve 6, the second float 702 moves downward to open the hole at the top of the second sub-valve 6, so that the gas enters the second sub-valve 6 and enters the pipeline through the second connecting pipe 5 and the valve body 1; the material and function of the trace exhaust sealing ring 705 are consistent with those of the large exhaust sealing ring 402.

[0034] Furthermore, after the water supply is cut off, a small amount of air is first introduced into the pipeline from the second sub-valve 6, and then air is continuously added into the pipeline from the first sub-valve 3. When the liquid is removed from the first sub-valve 3, the first float 401 moves to the bottom of the first sub-valve 3 and blocks the bottom opening of the first sub-valve 3, due to insufficient air intake, the air intake valve plate 101 is opened by vacuum suction to allow air to flow in.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
