Description

Technical Field

[0001] The utility model relates to the technical field of automatic exhaust of water pipes, in particular to an automatic exhaust device for a water supply pipeline. Background Technique

[0002] Before the water is supplied after the pipeline installation is completed, the pipeline is filled with air. When there is a large amount of air inside the water supply pipeline, the accumulation of gas in the pipeline will affect the flow rate and flow of water, reduce the efficiency of the water conveyance equipment, or when the gas accumulates, it may also cause the pipeline to deform or rupture due to gas accumulation. At this time, the main function of the exhaust valve is to remove the gas in the pipeline to improve the use efficiency of the water pipe and the water pump, and protect the pipeline from damage caused by negative pressure.

[0003] Specifically, when exhaust is required, the exhaust valve is usually set at the highest point and local highest point of the water supply pipeline. By using the buoyancy of water to control the buoyancy ball to block the exhaust port, when the buoyancy of water decreases or disappears, the exhaust port is opened. During the pipeline operation stage, the exhaust valve can exhaust a small amount of gas under high pressure, and timely discharge the small amount of air released in the water to prevent the accumulation of air in the pipeline from causing an air bag to hinder the water flow. This process requires controlling the discharge flow rate of the gas to ensure that the air can be effectively removed without affecting the water flow stability or causing system pressure fluctuations due to too fast or too much gas discharge. At the same time, because the exhaust valve cannot quickly inhale air, it will cause the water supply pipeline to be unable to effectively cope with the negative pressure situation, thus affecting the normal operation of the pipeline. Based on the above problems, we propose an automatic exhaust device for a water supply pipeline. Content of the Utility Model

[0004] The utility model provides an automatic exhaust device for a water supply pipeline, which solves the problems put forward in the background technique.

[0005] To achieve the above object, the utility model is realized through the following technical solutions: an automatic exhaust device for a water supply pipeline, including a valve body, a cavity is opened inside the valve body, and a buoyancy ball is arranged inside the cavity. An inlet is opened at the bottom of the valve body, and a water supply pipeline is fixedly connected through the inlet. An air inlet pipeline is fixedly connected above the valve body, and the air inlet pipeline is communicated with the cavity. A suction device is fixedly installed on one side of the air inlet pipeline close to the valve body;

[0006] And the suction device includes a motor, an impeller, and a first connecting rod. The inner ring of the air inlet pipeline is fixedly installed with a first connecting rod that intersects, and a motor is fixedly installed at the center through the first connecting rod, and the output shaft of the motor is fixedly connected with the impeller;

[0007] An adjusting device is fixedly installed above the interior of the air inlet duct. The adjusting device includes an annular adjuster, a central shaft, a second connecting rod, a transmission shaft, a rotating pulley, a transmission plate, adjusting vanes, and a rotating shaft. The inner ring of the air inlet duct is fixedly installed with second connecting rods that cross each other, and a central shaft is fixedly connected at the center through the second connecting rods. A rotating shaft is movably installed outside the central shaft, and the rotating shaft is fixedly connected with adjusting vanes. A plurality of rotating pulleys are fixedly installed on the outer ring of the air inlet duct. An annular adjuster is sleeved outside the plurality of rotating pulleys, and the plurality of rotating pulleys can limit the annular adjuster. The outer ring of the annular adjuster is movably sleeved with a transmission plate through a pin, and a transmission shaft is fixed at the bottom side of the transmission plate. One end of the transmission shaft extends into the interior of the air inlet duct and is fixedly installed with an adjusting vane. The adjusting vane is fixed to the transmission shaft, and at the same time, the transmission shaft is movably sleeved with the air inlet duct.

[0008] Optionally, a buoyancy rod is fixedly installed inside the buoyancy ball, and a sealing ring is fixedly connected to the outer ring of the buoyancy rod. A sealing member is fixedly connected at the connection between the air inlet duct and the cavity, and a gasket that can form a sealing fit with the sealing ring is fixedly installed inside the sealing member. A hole is opened at the bottom of the cavity, and the buoyancy rod is movably sleeved through the hole and the hole can limit it.

[0009] Optionally, a plurality of support rods are fixedly connected to the top of the air inlet duct, and a dust-proof cover is fixedly connected through the support rods. A filter screen is fixedly installed between one side of the air inlet duct and the top of the air inlet duct where the dust-proof cover is located.

[0010] Optionally, a rotating handle is fixedly installed on one side of the filter screen above the air inlet duct, and the rotating handle is fixedly connected with a gear through a bottom transmission shaft. A gear tooth is opened on one side of the annular adjuster and can be engaged with the gear.

[0011] Optionally, threads are opened inside the left and right side pipes of the water supply pipe and can be used to connect other pipes. A handle is fixedly installed above the right side of the water supply pipe, and the water inlet and outlet can be controlled by rotating the handle.

[0012] The present utility model has the following beneficial effects:

[0013] 1. For this automatic air exhaust device of the water supply pipeline, by rotating the rotating handle to drive the gear to rotate, since the gear is engaged with the annular adjuster, the annular adjuster can be driven to rotate. While the annular adjuster rotates, the transmission plate movably connected to it can be driven to move. Since the transmission plate is fixedly connected to the transmission shaft, the transmission shaft can be driven to rotate. While the transmission shaft rotates, the adjusting vanes connected to it can be driven to rotate to adjust the air exhaust volume, so as to control the discharge of gas.

[0014] 2. The automatic air vent device for the water supply pipeline drives the impeller to rotate through a motor to suck a large amount of air from the air inlet pipeline, so as to maintain a negative pressure inside the water supply pipeline. At the same time, when there is a negative pressure in the pipeline, it can quickly suck in air to prevent the water supply pipeline from being damaged due to negative pressure. In addition, when water enters the pipe, the buoyancy ball stops at the lower part of the cavity for a large amount of air exhaust. When the gas is exhausted, the water enters the valve and floats the ball up through the cavity to close and stop the air exhaust. In this way, even a small amount of gas naturally generated during the normal operation of the pipeline can be excluded in time, ensuring the safety and efficiency of the pipeline.
