Therefore, the gas drainage elbow can drain water from the second channel by operating the actuating assembly, and can also automatically drain water from the second section of the first pipeline, so that the gas in the gas transmission pipeline is continuously transported, avoiding excessive accumulation of water in the gas and causing gas transmission interruption.

DETAILED DESCRIPTION

[0018] like Figure 1 As shown, the gas delivery pipeline includes a first delivery pipeline 800, a second delivery pipeline 900 and a third delivery pipeline 1000. The first delivery pipeline 800 is horizontally arranged, the third delivery pipeline 1000 is vertically arranged and connected to the combustion chamber, the second delivery pipeline 900 is inclined and connects the first delivery pipeline 800 and the third delivery pipeline 1000, and the connection between the second delivery pipeline 900 and the third delivery pipeline 1000 forms a bent part of the gas delivery pipeline. Figure 1 It shows a situation where the water level accumulated at the bend of the gas transmission pipeline exceeds the bend, causing the gas to be unable to pass through the bend of the pipeline, resulting in interruption of gas transmission.

[0019] Given that Figure 1As shown in the situation, an embodiment of the present application provides a gas drainage elbow, which can avoid the interruption of gas transmission and maintain continuous transmission of gas in the gas transmission pipeline.

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] In the description of the present application, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limitations on the present application. The terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0022] The present application provides a gas drainage elbow, such as Figures 2 to 4 As shown, the gas drainage elbow includes a first pipe 100 , a second pipe 200 , a housing 300 , a valve core 400 and an actuating assembly 500 .

[0023] The first pipeline 100 is bent to form a first section 110 extending vertically upward and a second section 120 extending obliquely upward. The upper end of the first section 110 is used to connect to the gas delivery pipeline. Specifically, the first section 110 is connected to the plugging cover 700 at the bottom of the third delivery pipeline 1000 and communicates with the third delivery pipeline 1000.

[0024] One end of the second pipe 200 is connected to the first section 110. When the water level in the first pipe 100 exceeds the position of the second pipe 200, the water in the first pipe 100 flows toward the second pipe 200.

[0025] The housing 300 defines a first channel 310, a second channel 320 and a third channel 330. The axis of the second channel 320 coincides with the axis of the third channel 330, the second channel 320 and the third channel 330 are both connected and orthogonal to the first channel 310, and the first channel 310 and the second channel 320 are both connected to the outside of the housing 300.

[0026] For example, Figure 2 As shown, the housing 300 includes a first housing 380 and a second housing 390, and the first housing 380 and the second housing 390 are detachably connected; Figure 4 shows a schematic structural diagram of the first housing 380, Figure 5 A schematic structural diagram of the second housing 390 is shown.

[0027] The valve core 400 is movably installed in the third channel 330, and the end of the valve core 400 facing the second channel 320 is tapered. When the valve core 400 moves in a direction close to the second channel 320, the tapered end of the valve core 400 can press the port of the second channel 320, thereby blocking the first channel 310 and the second channel 320, and the water in the first channel 310 cannot flow out of the second channel 320. When the valve core 400 moves in a direction away from the second channel 320, the tapered end of the valve core 400 opens the port of the second channel 320, so that the first channel 310 and the second channel 320 are connected, and the water in the first channel 310 flows out of the second channel 320 to the outside of the housing 300.

[0028] The actuating assembly 500 is partially operably disposed in the housing 300 and connected to the valve core 400, and is configured to drive the valve core 400 to move along its own axis. A worker can operate the portion of the actuating assembly 500 located outside the housing 300 to cause the actuating assembly 500 to drive the valve core 400 to move along its own axis, and then the tapered end of the valve core 400 can press and open the port of the second channel 320.

[0029] The second pipe 200 is located in the first channel 310, and a gap is provided between the end of the second pipe 200 away from the first pipe 100 and the bottom of the first channel 310 to allow the valve core 400 to move. Water in the second pipe 200 can flow into the first channel 310, and when the valve core 400 opens the second channel 320, the water in the second pipe 200 passes through the first channel 310 and flows from the second channel 320 to the outside of the housing 300.

[0030] When the gas drainage elbow is in use, the first section 110 is connected to the bent part of the gas delivery pipeline, and water is kept at the bent part of the first pipeline 100, so that the gas delivery pipeline is isolated from the outside; the water in the gas delivery pipeline continuously enters the first pipeline 100 and accumulates at the bent part of the first pipeline 100. When the coke oven is used for a long time, the worker can operate the part of the actuating assembly 500 located outside the shell 300, so that the actuating assembly 500 drives the valve core 400 to move away from the second channel 320, so that the second pipeline 200 is connected to the second channel 320 through the first channel 310, and the valve core 400 located inside the first pipeline 100 is moved away from the second channel 320. The water above the second pipe 200 flows out from the second channel 320; then, the worker operates the part of the actuating assembly 500 located outside the housing 300, so that the actuating assembly 500 drives the valve core 400 to move in the direction close to the second channel 320, and the conical end of the valve core 400 presses the port of the second pipe 200, so that the first pipe 100 and the second pipe 200 are blocked; when the water in the first pipe 100 accumulates too quickly and the worker fails to waterproof the second channel 320 in time, the water level in the first pipe 100 rises, and after the water level is higher than the second section 120, the water in the first pipe 100 automatically flows out from the second section 120. Therefore, the gas drainage elbow can drain water from the second channel 320 by operating the actuating assembly 500, and can also automatically drain water from the second section 120 of the first pipe 100, so that the gas in the gas transmission pipeline is continuously transported, and the situation that the excessive accumulation of water in the gas leads to the interruption of gas transmission is avoided.

[0031] Reference Figures 3 to 5 The housing 300 further defines a receiving chamber 370 and a fourth channel 340. The third channel 330 and the fourth channel 340 are both connected to the receiving chamber 370, and the axis of the fourth channel 340 is parallel to the axis of the third channel 330. The actuating assembly 500 includes a push rod 510, a connecting member 520 and a spring 530. The push rod 510 is installed in the fourth channel 340 and is partially located in the housing 300. The connecting member 520 is located in the receiving chamber 370, and the two ends of the connecting member 520 are respectively connected to the valve core 400 and the part of the push rod 510 extending into the receiving chamber 370. The spring 530 is located in the receiving chamber 370, and the two ends of the spring 530 are respectively connected to the connecting member 520 and the inner wall of the receiving chamber 370, so as to apply an elastic force toward the second channel 320 to the valve core 400.

[0032] When the worker pushes the push rod 510 upward, the push rod 510 moves and drives the valve core 400 through the connecting piece 520, so that the conical end of the valve core 400 opens the second channel 320, and then the first channel 310 is connected with the second channel 320, and the spring 530 is further compressed. When the worker gradually releases the push rod 510, the spring 530 pushes the connecting piece 520 to move downward, and the connecting piece 520 drives the valve core 400 and the push rod 510 to move downward, and finally the conical end of the valve core 400 blocks the port of the second channel 320, blocking the first channel 310 from the second channel 320.

[0033] Continue to refer to Figures 3 to 5 The housing 300 further defines a fifth channel 350, the axis of the fifth channel 350 coincides with the axis of the fourth channel 340, and the inner diameter of the fifth channel 350 is greater than the inner diameter of the fourth channel 340. The push rod 510 includes a first push section 511 and a second push section 512 connected to each other; the first push section 511 is located in the fourth channel 340, and one end of the first push section 511 extends into the accommodating chamber 370 and is connected to the connecting member 520; the second push section 512 is at least partially located outside the housing 300, and the outer diameter of the second push section 512 is greater than the outer diameter of the first push section 511; when the push rod 510 is pushed, the second push section 512 moves in the fifth channel 350, and the first push section 511 moves in the fourth channel 340.

[0034] Since the space in the housing 300 is small, the first push section 511 with a smaller outer diameter occupies less space, while the second push section 512 with a larger outer diameter is convenient for workers to operate. In addition, the bottom of the fifth channel 350 can limit the second push section 512, limit the maximum moving distance of the push rod 510, and prevent the spring 530 from being over-compressed.

[0035] Exemplarily, the first pushing section 511 and the second pushing section 512 are integrally connected.

[0036] Furthermore, if Figure 6 As shown, the side of the connecting member 520 that is away from the valve core 400 protrudes upward to form a first positioning portion 521; Figure 4 and Figure 5 As shown, the inner wall of the accommodating chamber 370 protrudes downward to form a second positioning portion 371 ; two ends of the spring 530 are respectively disposed at the first positioning portion 521 and the second positioning portion 371 .

[0037] The first positioning portion 521 and the second positioning portion 371 can position the two ends of the spring 530 to prevent the end portions of the spring 530 from being offset during compression or release of the spring 530, and the two ends of the spring 530 only need to be pressed against the side of the connecting member 520 facing away from the valve core 400 and the inner wall of the accommodating chamber 370, thereby facilitating the installation of the spring 530.

[0038] like Figure 3 and Figure 6 As shown, the gas drainage elbow further includes a sealing ring 600 disposed on the outer circumferential surface of the valve core 400. When the valve core 400 moves, the sealing ring 600 is in close contact with the inner wall of the third channel 330. The sealing ring 600 can seal the valve core 400 and the inner wall of the third channel 330 to prevent the water and gas in the first channel 310 from flowing out of the third channel 330.

[0039] The housing 300 is detachably connected to the first pipe 100, so that the housing 300 is more firmly fixed relative to the first pipe 100 and the second pipe 200. Specifically, the housing 300 defines a sixth channel 360, which is used to surround the first pipe 100; the inner wall of the sixth channel 360 clamps the first pipe 100.

[0040] The valve core 400 is provided with a connecting hole connecting the second channel 320 and the accommodating chamber 370. The connecting hole can balance the air pressure of the accommodating chamber 370 and the outside of the housing 300, avoiding the air pressure in the accommodating chamber 370 to be too high or too low, and ensuring the smooth movement of the valve core 400 in its own axial direction.

[0041] Furthermore, in the embodiment of the present application, the first pipe 100 and the third pipe are made of transparent materials. For example, the first pipe 100 and the third pipe are made of resin or glass. Workers can visually observe the water level in the first pipe 100 and the second pipe 200, and then determine whether drainage is needed.

[0042] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0043] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
