Description

Technical Field

[0001] This utility model relates to the technical field of pipeline exhaust devices, and in particular to a composite exhaust valve. Background Technology

[0002] In many fields such as water supply and drainage systems, heating systems, and industrial pipeline transportation, the effective emission of gas in pipelines is a key factor in ensuring the stable operation of the system. With the continuous expansion of the scale of modern urban construction, the pipeline network of various infrastructures is becoming more and more complex and large in scale, which puts forward higher requirements for the efficiency and reliability of exhaust equipment.

[0003] Traditional single-port exhaust valves can only release a large amount of air when the system is initially filled with water or when there are large pressure fluctuations. However, for the trace amounts of gas generated during normal system operation, due to the large exhaust port diameter, it is difficult to achieve continuous and stable exhaust. In terms of air intake, if ordinary exhaust valves cannot promptly draw in external air to balance the pressure when the pressure in the pipeline decreases, it may lead to negative pressure in the pipeline, causing pipeline deformation or damage. Therefore, the above problems need to be addressed. Utility Model Content

[0008] Preferably, the top cover has a first sliding groove extending longitudinally, the connecting rod is located in the first sliding groove, and a telescopic baffle is installed between the moving rod and the first sliding groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of the first vent hole, the second vent hole, and the micro vent, facilitates the venting of water through the first and second vent holes when the water pressure is high, and the venting of water through the micro vent when the water pressure is low, thereby achieving continuous and stable micro-venting and ensuring normal operation of the pipeline; furthermore, through the cooperation of the suspended ball, the connecting rod, and the moving rod, it is easy to press the moving rod inward, thereby driving the suspended ball down, and the water storage tank is connected to the first vent hole again, realizing the intake of air into the pipeline; finally, it solves the problem that the vent hole diameter of the existing device is too large, making it difficult to achieve continuous and stable micro-venting and unable to draw in air.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4This utility model discloses a composite exhaust valve, comprising a flange 1 for easy installation on a drain pipe; a main body 2 is mounted on the upper end of the flange 1 for easy venting; multiple equidistant first exhaust holes 3 are opened on the outer side of the upper end of the main body 2 for easy discharge of large amounts of gas; a top cover 4 is mounted on the top of the main body 2 for easy installation of a pressure gauge; a pressure gauge is mounted on the top cover 4; an exhaust pipe is connected to one side of the main body 2, and a miniature exhaust device 5 is mounted on the other end of the exhaust pipe for easy discharge of smaller pressure gases. A small amount of air is discharged; a filter screen 6 is installed on the inner bottom of the main body 2 to prevent impurities from entering the interior of the main body 2; a water storage tank 7 is installed directly above the filter screen 6, and multiple equidistant water inlets are opened on the outer side of the lower end of the water storage tank 7, and the outer side of the top of the water storage tank 7 is fixedly connected to the inner side of the main body 2; a suspended ball 8 is installed directly above the interior of the water storage tank 7, which facilitates the cooperation with the sealing ring 13; a sliding rod 9 is installed on the upper end of the suspended ball 8, which facilitates the up and down movement of the connecting rod 10; the upper ends of the sliding rod 9 are hinged to the connecting rods 10 on both sides, which facilitates the cooperation with the moving rod 11.

[0020] In this invention, each of the two connecting rods 10 has a movable rod 11 hinged to its other end, which facilitates the lifting and lowering of the suspended ball 8. The top cover 4 has a first sliding groove extending longitudinally, the connecting rod 10 is located in the first sliding groove, and a telescopic baffle 12 is installed between the movable rod 11 and the first sliding groove to prevent external impurities from entering the interior of the main body 2. A second sliding groove is longitudinally opened on the bottom surface of the first sliding groove, and the connecting rod 10 and the movable rod 11 are hinged and slidably connected in the second sliding groove. An exhaust plate 14 is sleeved on the sliding rod 9, which facilitates the cooperation with the first exhaust hole 3. Multiple second exhaust holes are opened on the periphery of the top surface of the exhaust plate 14, and a sealing ring 13 is fixedly connected to the bottom end of the exhaust plate 14. The sealing ring 13 facilitates the cooperation with the suspended ball 8 to divide the interior of the main body 2 into two chambers. The outer side of the sealing ring 13 is fixedly connected to the inner side of the main body 2, and the inner diameter of the sealing ring 13 is smaller than the maximum diameter of the suspended ball 8.

[0021] Working Principle: When using this invention, the device is first installed on the drain pipe via flange 1. When the drain pipe is first opened, there is a large amount of gas inside. The gas enters the water storage tank 7 through the filter screen 6, then passes through the suspended ball 8 through the second vent hole, and finally exits through the first vent hole 3. As the gas decreases, the air pressure decreases, and the water pressure increases. Some water will enter the body 2 under high pressure. At this time, the filter screen 6 can prevent impurities in the water from entering the body 2, thus extending the service life of the device. After the liquid enters, it pushes the suspended ball 8 to rise. With the cooperation of the slide rod 9 and the connecting rod 10, it drives the moving rod 11 to move to both sides. At the same time, the telescopic baffle 12 extends and retracts in coordination with the moving rod 11 to prevent external impurities from entering the body 2. When the suspended ball 8 abuts against the sealing ring 13, the body 2 is divided into two chambers. At this time, there is a small amount of air in the water, which is discharged through the vent pipe and the miniature vent 5. When air needs to be introduced, simply push the moving rod 11 inward, and the suspended ball 8 descends. At this time, the water storage tank 7 is connected to the first vent hole 3.
