Description

Technical Field

[0001] This utility model relates to the field of pipeline equipment, and in particular to a venting device for pipelines. Background Technology

[0002] After the desulfurization system is installed, the pump needs to be inspected and maintained. A check valve is installed after the pump exits (to prevent liquid from flowing back into the pipeline). The installation of the check valve prevents the liquid in the pump outlet pipeline from being discharged and accumulates in the pipeline. If the pump is disassembled and hoisted, a large amount of liquid will flow out, which is inconvenient for pump inspection and maintenance. Utility Model Content

[0003] The purpose of this utility model is to provide a drainage device for pipelines that improves the drainage effect between the inlet pipe and the outlet pipe, and can prevent backflow of sediment or reduce the impact of water flow on the pipeline.

[0004] To solve the above-mentioned technical problems, this utility model provides a venting device for pipelines, including a venting pipeline, an inlet pipe connected to one end of the venting pipeline, and an outlet pipe connected to the other end of the venting pipeline. When the outlet pipe is placed horizontally, the end of the venting pipeline is inclined downward at a first angle and connected to the outlet pipe. When the inlet pipe is placed horizontally, the end of the venting pipeline is inclined upward at a second angle and connected to the outlet pipe.

[0005] Furthermore, a connecting assembly is provided at the connection between the discharge pipeline and the outlet pipe. The connecting assembly includes a connecting pipe for connecting the discharge pipeline and a secondary pipe for connecting the outlet pipe. A movable pipe is movably connected between two adjacent connecting pipes. The secondary pipe is connected to the movable pipe. When two adjacent connecting pipes are close to each other, the adjacent connecting pipe clamps and fixes the movable pipe.

[0006] Furthermore, a retaining ring is provided circumferentially at one end of the connecting pipe near the movable pipe. The retaining ring has several positioning grooves circumferentially, and the positioning grooves on two adjacent connecting pipes correspond to each other so that the secondary pipe is engaged in the positioning groove.

[0007] Furthermore, several connecting plates are spaced circumferentially on the side of the connecting pipe closest to the movable pipe, and adjacent connecting pipes are fixed together with the connecting plates by tie bolts.

[0008] Furthermore, a positioning ring is provided circumferentially on the inner side of the connecting pipe, and the end of the movable pipe matches the positioning ring so that when the secondary pipe is engaged in the positioning groove, the end of the movable pipe abuts against the positioning ring.

[0009] Furthermore, the positioning ring is inclined on the side away from the moving tube, and a sealing ring is provided circumferentially at the end of the moving tube.

[0010] Furthermore, the first angle is 40°-50°.

[0011] Furthermore, the second angle is 40°-50°.

[0012] Furthermore, a valve body is installed at the discharge pipeline, and a check valve is installed at the outlet pipe.

[0013] The beneficial effects of this utility model are as follows: By connecting the pump body between the inlet pipe and the outlet pipe, and connecting the vent pipe between the inlet pipe and the outlet pipe, the pump body is connected to the vent pipe. Since there is a problem that the liquid in the pump outlet pipe cannot be discharged and accumulates in the pipe, this solution can temporarily discharge the liquid at the pump outlet through the vent pipe, thereby improving the liquid discharge effect in the pipe without disassembling the pump body.

[0014] Meanwhile, when the outlet pipe is placed horizontally, by connecting the discharge pipe to the outlet pipe at a certain downward angle, the liquid in the outlet pipe will not flow back into the discharge pipe, thereby preventing liquid, mud, etc. from flowing back into the discharge pipe and the pump body, so as to avoid interference with the operation of the pump body.

[0015] When the inlet pipe is placed horizontally, the impact force of the water flow is relatively large. Therefore, by tilting the end of the discharge pipe upward at a certain angle and connecting it to the outlet pipe, the direct impact of the water flow on the outlet pipe can be effectively reduced.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0023] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0024] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0025] like Figures 1-5 The present invention provides a venting device for a pipeline, comprising a venting pipeline 1, an inlet pipe 3 connected to one end of the venting pipeline 1, and an outlet pipe 2 connected to the other end of the venting pipeline 1. When the outlet pipe 2 is placed horizontally, the end of the venting pipeline 1 is inclined downward at a first angle to connect with the outlet pipe 2. When the inlet pipe 3 is placed horizontally, the end of the venting pipeline 1 is inclined upward at a second angle to connect with the outlet pipe 2.

[0026] The pump body is connected between the inlet pipe and the outlet pipe, and the vent pipe is connected between the inlet pipe and the outlet pipe, so that the pump body is connected to the vent pipe. Since there is a problem that the liquid in the pump outlet pipe cannot be discharged and accumulates in the pipe, this solution can temporarily discharge the liquid at the pump outlet through the vent pipe, thereby improving the liquid discharge effect in the pipe without disassembling the pump body.

[0027] Meanwhile, when the outlet pipe is placed horizontally, by connecting the discharge pipe to the outlet pipe at a certain downward angle, the liquid in the outlet pipe will not flow back into the discharge pipe, thereby preventing liquid, mud, etc. from flowing back into the discharge pipe and the pump body, so as to avoid interference with the operation of the pump body.

[0028] When the inlet pipe is placed horizontally, the impact force of the water flow is relatively large. Therefore, by tilting the end of the discharge pipe upward at a certain angle and connecting it to the outlet pipe, the direct impact of the water flow on the outlet pipe can be effectively reduced.

[0029] It is worth mentioning that the venting pipeline has multiple ports, which are used to connect to the inlet pipe, the outlet pipe, and the vent for venting liquid. If there are multiple pipeline connections, they can all be connected to different ports of the venting pipeline to ensure pipeline connectivity. The pump body is located at the venting pipeline to assist the liquid in flowing from the inlet pipe through the pump body and into the outlet pipe. The vent is specifically used to discharge the liquid accumulated in the venting pipeline and the pump body and is not activated during normal use.

[0030] Wherein, the first angle is 40°-50°, the second angle is 40°-50°, and in the preferred embodiment of this solution, the first angle is 45° and the second angle is 45°.

[0031] In one embodiment of this solution, a valve body is provided at the discharge pipeline to control the discharge of liquid from the discharge pipeline. The valve body can be pneumatically controlled. A check valve is provided at the outlet pipe to prevent liquid from flowing back from the outlet pipe. The diameter of the discharge pipeline is DN50.

[0032] Preferably, a connecting assembly is provided at the connection between the discharge pipeline and the outlet pipe. The connecting assembly includes a connecting pipe 11 for connecting the discharge pipeline and a secondary pipe 12 for connecting the outlet pipe. A movable pipe 13 is movably connected between two adjacent connecting pipes 11. The secondary pipe 12 is connected to the movable pipe 13. When two adjacent connecting pipes 11 are close to each other, the adjacent connecting pipes 11 clamp and fix the movable pipe 13.

[0033] Specifically, since the angle between the outlet pipe and the discharge pipe is limited, it needs to be adjusted according to the horizontal setting of the outlet pipe or the inlet pipe. Therefore, the angle between the secondary pipe and the connecting pipe will change under different installation positions and usage adjustments. That is, the movable pipe and the connecting pipe are in a rotating fit. After the angle of the secondary pipe is adjusted, the two adjacent connecting pipes are brought close to each other and the sides of the secondary pipe are clamped and fixed so that the secondary pipe can stably maintain the current angle, thereby ensuring the connection angle of the outlet pipe.

[0034] It is worth mentioning that both adjacent connecting pipes can be connected to the drain pipe, or one connecting pipe can be connected to the drain pipe while the other connecting pipe is sealed. In this case, the sealed connecting pipe is only used to fix the secondary pipe and does not play a role in liquid transportation.

[0035] Preferably, a retaining ring 14 is provided circumferentially at one end of the connecting pipe 11 near the movable pipe 13. The retaining ring 14 has several positioning grooves 15 circumferentially, and the positioning grooves 15 on two adjacent connecting pipes 11 correspond to each other so that the secondary pipe 12 is engaged in the positioning grooves 15.

[0036] Specifically, when fixing the secondary pipe through the connecting pipe, the positioning grooves at the two adjacent retaining rings engage with the sides of the secondary pipe, so that when the two adjacent positioning grooves are close together, they form an annular fixing groove, thereby fixing the secondary pipe in the fixing groove and improving the angular stability of the secondary pipe.

[0037] In one embodiment of this solution, the positioning groove is configured in a semi-circular shape.

[0038] Preferably, a plurality of connecting plates 16 are provided circumferentially at intervals on the side of the connecting pipe 11 near the movable pipe 13, and adjacent connecting pipes 11 are fixed together with the connecting plates 16 by tie bolts.

[0039] Specifically, after the connecting pipe and the retaining ring are used to position the secondary pipe, the corresponding two connecting plates are connected by tie bolts, so that the two adjacent connecting pipes are connected and fixed by tie bolts, and the retaining ring is used to clamp the secondary pipe firmly.

[0040] Preferably, a positioning ring 17 is provided circumferentially on the inner side of the connecting pipe 11, and the end of the movable pipe 13 matches the positioning ring 17 so that when the secondary pipe 12 is engaged in the positioning groove 15, the end of the movable pipe 13 abuts against the positioning ring 17.

[0041] Specifically, during the process of clamping the secondary pipe as two adjacent connecting pipes approach each other, the end of the movable pipe approaches and eventually abuts against the positioning ring, so that the end of the movable pipe abuts against the positioning ring to maintain the waterproof effect between the movable pipe and the connecting pipe and avoid water leakage at the connection.

[0042] Preferably, the positioning ring 17 is inclined on the side away from the movable tube 13, and a sealing ring 18 is provided circumferentially at the end of the movable tube 13.

[0043] Specifically, the sealing ring enhances the sealing effect between the movable pipe and the positioning ring, thereby strengthening the leak-proof treatment.

[0044] Meanwhile, by setting the positioning ring at an angle on the side away from the movable pipe, the water flow can be reduced by the inclined structure when it flows through the positioning ring, ensuring smooth water flow at the junction of the connecting pipe and the movable rod.

[0045] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
