Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of exhaust valves, in particular to an exhaust valve for a water supply pipeline. Background Art
[0002] An exhaust valve, also known as a bleed valve or vent valve, is an indispensable device in a piping system. Its primary function is to quickly remove air from the pipe, thereby improving the efficiency of water delivery equipment and preventing pipe deformation or rupture due to gas accumulation. Typically installed at pump outlets or in water distribution lines, this device is used to eliminate air accumulation in the pipe, thereby improving the operating efficiency of the pipes and pumps. Dissolved gases in water precipitate as temperature rises, and gases generated during pipeline maintenance or renovation all need to be discharged through the exhaust valve. When negative pressure occurs within the pipe, the exhaust valve can quickly draw in outside air, protecting the pipe from damage. Therefore, the exhaust valve plays a key role in the water supply system. Installing an exhaust valve in a water supply pipe is essential to ensure smooth water flow and safe operation. However, when the amount of gas in the water supply pipe is large or the pressure is high, the existing drain valve has a small vent hole, resulting in a prolonged exhaust time and failing to meet exhaust requirements. To address this issue, we propose a water supply pipe exhaust valve. Utility Model Content
[0003] The purpose of the present utility model is to provide a water supply pipe exhaust valve to solve the problem proposed in the above background technology that when the amount of gas in the water supply pipe is large or the pressure is high, the exhaust time of some drain valves is prolonged due to the small exhaust hole, and the exhaust demand cannot be met.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water supply pipe exhaust valve, comprising a connecting pipe, a valve provided on the side of the connecting pipe, a water stop valve inside the valve, a runner rotatably connected to the outside of the water stop valve, the runner and the valve threaded connection, a ball plug tube fixedly connected to the top of the connecting pipe, a spherical plug provided in the ball plug tube, an exhaust pipe fixedly connected to the top of the ball plug tube, and an exhaust device also provided in the exhaust pipe.
[0005] The valve is in a horizontally placed terrace shape, and the end with a larger valve area is connected to the connecting pipe.
[0006] Among them, the water stop valve is round, and rubber plugs are fixedly installed on the upper and lower parts of the water stop valve.
[0007] Among them, the ball plug tube is a cavity that is thick in the middle and thin at both ends.
[0008] The diameter of the spherical plug is slightly larger than the diameters of the two ends of the spherical plug tube, and the spherical plug can slide freely in the spherical plug tube.
[0009] Among them, the exhaust device includes a sliding sleeve, which is fixedly connected to the exhaust pipe. A sealing ring is provided in the sliding sleeve. A sliding rod is fixedly connected to the upper part of the spherical plug. The sliding rod can slide freely in the sliding sleeve. A spring is provided between the upper part of the sliding rod and the exhaust pipe. An air plug is provided in the middle of the spring. The air plug is slidably connected to the exhaust pipe. Four exhaust holes are opened on the upper part of the exhaust pipe.
[0010] Among them, the four sides of the gas plug are fixedly connected with plug rods, the plug rods are located at different heights, and the plug rods can be plugged into the exhaust holes.
[0011] The utility model has at least the following beneficial effects:
[0012] Through the exhaust device, when the amount of gas in the water supply pipe is large or the pressure is high, when the water stop valve is opened, the gas can enter the exhaust valve, the spherical plug is pushed by the gas, and the spherical plug leaves the lower end of the spherical plug tube. At this time, the exhaust valve is in an open state, and the spherical plug drives the sliding rod to slide in the sliding sleeve and pushes the plug rod on the gas plug out of the exhaust hole. Since there are four exhaust holes and the height and length of the plug rod are different, a sufficient number of exhaust holes can be automatically opened under different gas amounts and pressures, so that the gas in the water supply pipe can be discharged in time, thereby improving the exhaust efficiency.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] Example 1
[0020] See also Figures 1 to 3 The utility model provides a technical solution: a water supply pipe exhaust valve, including a pipe 1, a valve 2 is provided on the side of the pipe 1, the valve 2 is a horizontal step-shaped valve 2, the end of the valve 2 with a larger area is connected to the pipe 1, a water stop valve 3 is provided in the valve 2, the water stop valve 3 is round, and a rubber plug 30 is fixedly installed on the upper and lower parts of the water stop valve 3, a runner 4 is rotatably connected to the outer side of the water stop valve 3, the runner 4 is threadedly connected to the valve 2, a ball plug tube 5 is fixedly connected to the top of the pipe 1, the ball plug tube 5 is a cavity with a thick middle and thin ends, and the ball plug tube 5 is a cavity with a thick middle and thin ends. A spherical plug 6 is provided inside, and the diameter of the spherical plug 6 is slightly larger than the diameter of the two ends of the spherical plug tube 5. The spherical plug 6 can slide freely in the spherical plug tube 5. When the water stop valve 3 is opened, the gas in the water supply pipe can enter the exhaust valve. The spherical plug 6 is pushed by the gas and leaves the lower end of the spherical plug tube 5, so that the exhaust valve is in an open state. If there is no gas in the water supply pipe, the spherical plug 6 will be pushed to the top of the spherical plug tube 5, so that the exhaust valve is closed. An exhaust pipe 7 is fixedly connected above the spherical plug tube 5, and an exhaust device 8 is also provided in the exhaust pipe 7.
[0021] The exhaust device 8 includes a sliding sleeve 80, which is fixedly connected to the exhaust pipe 7. A sealing ring 81 is provided in the sliding sleeve 80. A sliding rod 82 is fixedly connected to the upper part of the spherical plug 6. The sliding rod 82 can slide freely in the sliding sleeve 80. A spring 83 is provided between the upper part of the sliding rod 82 and the exhaust pipe 7. An air plug 84 is provided in the middle of the spring 83. The air plug 84 is slidably connected to the exhaust pipe 7. A plug rod 840 is fixedly connected to each of the four sides of the air plug 84. The plug rod 840 is at different heights. Four exhaust holes 85 are opened on the upper part of the exhaust pipe 7. The plug rod 8 40 can be plugged into the exhaust hole 85. After the gas in the water supply pipe pushes the spherical plug 6, the plug rod 840 on the air plug 84 is pushed out of the exhaust hole 85. Since there are four exhaust holes 85 and the height and length of the plug rod 840 are different, when the air pressure is high, the air plug 84 is pushed a longer distance and the number of exhaust holes 85 opened is more. When the gas in the water supply pipe is less, the air plug 84 is pushed a shorter distance and the number of exhaust holes 85 opened becomes less. Therefore, the exhaust volume can be automatically controlled according to the different air pressures in the pipe.
[0022] Example 2
[0023] like Figure 4 In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that a protective cover 9 is added outside the exhaust pipe 7 to prevent debris from entering the exhaust hole 85 and causing blockage.
