Description

Technical Field

[0001] The utility model relates to the technical field of wet relief, in particular to a wet relief device with a floating ball type antifreeze addition. Background Technique

[0002] Wet relief devices are widely used in the safety engineering of gas relief in medium and low-pressure pipelines and in occasions such as coal mine pipeline gas and low-pressure pipeline gas; its working principle is to ensure that related equipment (such as coal mine water ring vacuum pumps, gas transmission systems, etc.) works within a set pressure range. When the system pipeline pressure increases, the water surface in the inner sleeve drops and the water surface in the outer sleeve rises; when the water surface in the inner sleeve drops to expose the lower edge of the inner sleeve, gases such as gas will overflow and be emptied through the water, and the gas is emptied into the air through the water, so that the possible external fire source can be isolated from the gas in the system to achieve safe relief.

[0003] In winter or in areas with low temperatures throughout the year, the water in wet relief equipment will freeze. The frozen water will block the wet relief equipment, making it impossible to use the wet relief equipment normally. Therefore, antifreeze is used instead of water in low-temperature areas. Antifreeze will not freeze to prevent the wet relief equipment from being blocked; Chinese Patent Publication No. CN206669042 U discloses a liquid seal safety relief valve, including a water seal inlet pipe, a liquid seal, a water seal box, a gas storage cylinder, a water seal outlet pipe and a relief vertical pipe. The water seal inlet pipe is arranged on the upper part of the water seal box, the water seal inlet pipe is communicated with the inside of the water seal box and extends to the bottom of the water seal box. The water seal outlet pipe is arranged on the upper part of the side surface of the water seal box, the water seal outlet pipe is communicated with the water seal box, the liquid seal is arranged inside the gas storage cylinder, the water seal outlet pipe is connected with the relief vertical pipe, and the gas storage cylinder is arranged upside down and communicated with the upper part of the water seal box;

[0004] For the above relief valve, the antifreeze is located in the water seal box. When relief work is carried out, due to the relatively high gas pressure in the water seal inlet pipe, its moving speed is very fast, so a small amount of antifreeze will be carried into the water seal outlet pipe; after multiple reliefs, the antifreeze in the relief valve will be significantly reduced. To ensure the normal progress of subsequent relief work, the staff needs to manually open the water injection hole plug and add antifreeze to the water seal box through the water injection hole. However, due to the material of the water seal box, it is not transparent, so the staff cannot accurately know the amount of antifreeze in the water seal box in the first time. Therefore, the staff needs to frequently check the liquid level of the antifreeze, which not only increases the workload of the staff, but also affects the normal progress of the relief work. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a wet blow-off device with a floating ball type for adding antifreeze. A floating ball assembly is arranged in the inner chamber. The floating ball assembly floats on the liquid surface. When the liquid level drops, the floating ball assembly no longer blocks the connecting pipe, and the antifreeze in the connecting pipe will flow into the inner chamber. As the liquid level of the antifreeze in the inner chamber rises, the floating ball assembly rises synchronously and blocks the connecting pipe, and the antifreeze in the connecting pipe no longer flows into the inner chamber, thereby realizing the automatic addition of antifreeze into the inner chamber by using the floating ball assembly to solve the technical problems proposed in the above background technology.

[0006] To achieve the above object, the present utility model provides the following technical solutions:

[0007] A wet blow-off device with a floating ball type for adding antifreeze, including an outer cylinder. An inner cylinder is arranged inside the outer cylinder, and an inner pipe is arranged inside the inner cylinder. The upper end of the inner pipe is located outside the inner cylinder.

[0008] A connecting pipe is welded to the upper end of the outer cylinder and extends to the inside of the inner cylinder. One end of the connecting pipe located inside the inner cylinder is fixedly connected to the floating ball assembly.

[0009] The floating ball assembly includes a sleeve. The sleeve is hollow, and one side of the upper end of the sleeve is welded to the connecting pipe. Circular through holes are arranged on both sides of the upper end of the sleeve. A moving plate is arranged inside the sleeve, and the bottom of the moving plate is welded to a connecting piece. A floating ball is arranged on one side of the connecting piece away from the moving plate. A floating ring is arranged outside the floating ball and is fixedly connected to the connecting piece.

[0010] As a further technical solution of the present utility model, the outer cylinder is cylindrical, and an air inlet is welded to one side of the lower end of the outer cylinder, and an air outlet is welded to the side of the outer cylinder away from the air inlet. The space between the outer cylinder and the inner cylinder is an outer chamber, and both the air inlet and the air outlet are communicated with the outer cylinder. The top of the inner pipe is located at the upper end of the outer chamber.

[0011] As a further technical solution of the present utility model, the space between the inner pipe and the inner cylinder is an inner chamber for placing antifreeze. The inner pipe is L-shaped, and the bottom height of the inner pipe is higher than the bottom height of the inner cylinder. The outer chamber is communicated with the inner chamber through the inner pipe.

[0012] As a further technical solution of the present utility model, the upper end of the inner cylinder extends above the outer cylinder, and the top of the inner cylinder is welded to the bottom of the blow-off pipe. A plurality of blow-off ports are evenly arranged on the blow-off pipe. A top cap is welded to the top of the blow-off pipe, and the diameter of the top cap is larger than the diameter of the blow-off pipe.

[0013] As a further technical solution of the present utility model, the moving plate fits the inner wall of the sleeve, and the length of the moving plate is greater than the length of the sleeve. The diameter of the circular through hole at the upper end of the sleeve is the same as the inner diameter of the connecting pipe. One end of the connecting pipe away from the sleeve is fixedly connected to the antifreeze storage device, and both the air outlet and the air inlet are fixedly connected to the gas transportation pipeline.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. In the present utility model, gas enters the outer chamber through the air inlet, and then is discharged from the outer layer through the air outlet. The gas located in the outer chamber will enter the interior of the inner tube; the inner tube is communicated with the inner chamber. Therefore, under normal air pressure, the liquid level of the antifreeze in the inner chamber is flush with the liquid level of the antifreeze in the inner tube; when the air pressure in the gas transportation pipeline increases, the gas pressure in the inner tube will also increase, and the air pressure will suppress the antifreeze in the inner tube downward until the gas is discharged from the bottom of the inner tube and enters the inner chamber; the gas in the inner chamber moves upward and enters the relief pipe, and then is discharged through the relief port of the relief pipe; the top cap at the top of the relief pipe serves to cover the relief pipe and prevent external dust and other impurities from falling into the inner chamber through the relief pipe;

[0016] 2. In the present utility model, as the number of times of relief increases, the antifreeze in the inner chamber gradually decreases and the liquid level gradually drops. As the liquid level drops, the floating ball floating on the liquid surface synchronously descends. When the floating ball descends, it drives the moving plate to descend through the connecting member. After the moving plate descends, it no longer blocks the circular through-hole of the sleeve. The antifreeze in the connecting pipe will flow into the inner chamber through the circular through-hole of the sleeve, realizing the automatic addition of antifreeze into the inner chamber; after the liquid level of the antifreeze in the inner chamber rises, the floating ball synchronously rises, and the moving plate also rises following the floating ball until the moving plate blocks the circular through-hole of the sleeve. At this time, the antifreeze in the connecting pipe is blocked and no longer enters the inner chamber; through the cooperation of the floating ball and the moving plate, it can not only realize the automatic addition of antifreeze, but also keep the highest liquid level of the antifreeze in the inner chamber always at the same position, so that the pressure of the antifreeze in the inner chamber is always the same.

[0033] The described floating ball assembly 9 includes a housing 91 which is hollow, and one side of the upper end of the housing 91 is welded to the connecting pipe 7; circular through holes are provided on both sides of the upper end of the housing 91; a moving plate 94 is provided inside the housing 91, and the bottom of the moving plate 94 is welded to the connecting member 95; a floating ball 92 is provided on the side of the connecting member 95 away from the moving plate 94, a floating ring 93 is provided outside the floating ball 92, and the floating ring 93 is fixedly connected to the connecting member 95.

[0034] By adopting the above technical solution, gas enters the outer chamber 10 through the air inlet 2, and then is discharged from the outer layer through the air outlet 3, and the gas located in the outer chamber 10 will enter the interior of the inner tube 8; the inner tube 8 is communicated with the inner chamber 11, so under normal air pressure, the liquid level of the antifreeze in the inner chamber 11 is flush with the liquid level of the antifreeze in the inner tube 8; when the air pressure in the gas transportation pipeline increases, the gas pressure in the inner tube 8 will also increase, and the air pressure will press down the antifreeze in the inner tube 8 until the gas is discharged from the bottom of the inner tube 8 and enters the inner chamber 11; the gas in the inner chamber 11 moves upward and enters the relief pipe 5, and then is discharged through the relief port of the relief pipe 5; the top cap 6 at the top of the relief pipe 5 serves to cover the relief pipe 5 to prevent foreign dust and other impurities from falling into the inner chamber 11 through the relief pipe 5.

[0035] In this embodiment, the outer cylinder 1 is cylindrical, and an air inlet 2 is welded to one side of the lower end of the outer cylinder 1, and an air outlet 3 is welded to the side of the outer cylinder 1 away from the air inlet 2; the space between the outer cylinder 1 and the inner cylinder 4 is the outer chamber 10, and both the air inlet 2 and the air outlet 3 are communicated with the outer cylinder 1; the top of the inner tube 8 is located at the upper end of the outer chamber 10;

[0036] The space between the inner tube 8 and the inner cylinder 4 is the inner chamber 11 for placing antifreeze; the inner tube 8 is L-shaped, and the bottom height of the inner tube 8 is higher than the bottom height of the inner cylinder 4; the outer chamber 10 is communicated with the inner chamber 11 through the inner tube 8;

[0037] The upper end of the inner cylinder 4 extends above the outer cylinder 1, and the top of the inner cylinder 4 is welded to the bottom of the relief pipe 5; a plurality of relief ports are evenly provided on the relief pipe 5; a top cap 6 is welded to the top of the relief pipe 5, and the diameter of the top cap 6 is larger than the diameter of the relief pipe 5;

[0038] The moving plate 94 fits against the inner wall of the housing 91, and the length of the moving plate 94 is greater than the length of the housing 91; the diameter of the circular through hole at the upper end of the housing 91 is the same as the inner diameter of the connecting pipe 7, and the end of the connecting pipe 7 away from the housing 91 is fixedly connected to the antifreeze storage device, and both the air outlet 3 and the air inlet 2 are fixedly connected to the gas transportation pipeline.

[0039] By adopting the above technical solution, as the number of times of discharging increases, the antifreeze in the inner chamber 11 gradually decreases, and the liquid level gradually drops. As the liquid level drops, the floating ball 92 floating on the liquid surface synchronously descends. When the floating ball 92 descends, it drives the moving plate 94 to descend through the connecting member 95. After the moving plate 94 descends, it no longer blocks the circular through-hole of the sleeve 91, and the antifreeze in the connecting pipe 7 will flow into the inner chamber 11 through the circular through-hole of the sleeve 91, realizing the automatic addition of antifreeze into the inner chamber 11. After the liquid level of the antifreeze in the inner chamber 11 rises, the floating ball 92 synchronously rises, and the moving plate 94 also rises following the floating ball 92 until the moving plate 94 blocks the circular through-hole of the sleeve 91. At this time, the antifreeze in the connecting pipe 7 is blocked and no longer enters the inner chamber 11. By cooperating the floating ball 92 with the moving plate 94, it can not only realize the automatic addition of antifreeze, but also make the highest liquid level of the antifreeze in the inner chamber 11 always stay at the same position, so that the pressure of the antifreeze in the inner chamber 11 is always the same.

[0040] The working principle of the present utility model is as follows: The gas enters the outer chamber 10 through the air inlet 2, and then is discharged from the outer layer through the air outlet 3, and the gas located in the outer chamber 10 will enter the inside of the inner pipe 8; the inner pipe 8 is communicated with the inner chamber 11. Therefore, under normal air pressure, the liquid level of the antifreeze in the inner chamber 11 is flush with the liquid level of the antifreeze in the inner pipe 8; when the air pressure in the gas transportation pipeline increases, the gas pressure in the inner pipe 8 will also increase, and the air pressure will press down the antifreeze in the inner pipe 8 until the gas is discharged from the bottom of the inner pipe 8 and enters the inner chamber 11; the gas in the inner chamber 11 moves upward and enters the discharge pipe 5, and then is discharged through the discharge port of the discharge pipe 5; the top cap 6 at the top of the discharge pipe 5 serves to cover the discharge pipe 5 to prevent foreign dust and other impurities from falling into the inner chamber 11 through the discharge pipe 5;

[0041] By adopting the above technical solution, as the number of times of discharging increases, the antifreeze in the inner chamber 11 gradually decreases, and the liquid level gradually drops. As the liquid level drops, the floating ball 92 floating on the liquid surface synchronously descends. When the floating ball 92 descends, it drives the moving plate 94 to descend through the connecting member 95. After the moving plate 94 descends, it no longer blocks the circular through-hole of the sleeve 91, and the antifreeze in the connecting pipe 7 will flow into the inner chamber 11 through the circular through-hole of the sleeve 91, realizing the automatic addition of antifreeze into the inner chamber 11. After the liquid level of the antifreeze in the inner chamber 11 rises, the floating ball 92 synchronously rises, and the moving plate 94 also rises following the floating ball 92 until the moving plate 94 blocks the circular through-hole of the sleeve 91. At this time, the antifreeze in the connecting pipe 7 is blocked and no longer enters the inner chamber 11. By cooperating the floating ball 92 with the moving plate 94, it can not only realize the automatic addition of antifreeze, but also make the highest liquid level of the antifreeze in the inner chamber 11 always stay at the same position, so that the pressure of the antifreeze in the inner chamber 11 is always the same.
