Description

Technical Field

[0001] The utility model relates to the field of drainage pipelines, in particular to an exhaust valve and a device for realizing automatic emptying of sewage pipelines. Background Art

[0002] In the process of oil and gas field development, especially large-scale projects such as the Yuanba Gas Field of the Second Gas Production Plant of the Southwest Oil and Gas Branch of Sinopec, wastewater treatment and reinjection or external transmission are key links to ensure production safety, environmental protection and efficient use of resources. As an important natural gas production base, the efficient and stable operation of the wastewater treatment system of the Yuanba Gas Field is of great significance to maintaining the production efficiency and environmental friendliness of the entire gas field.

[0003] At present, Yuanba Gas Field generally uses diaphragm pumps, lifting pumps and other high-efficiency equipment in the sewage transport link. These equipment have been widely used in the field of oil and gas field sewage treatment due to their good sealing, corrosion resistance and flexibility of flow regulation. However, in the actual operation process, a problem that cannot be ignored gradually emerged: when it is necessary to clean the Y-type filter before the pump, maintain the external transport pump or perform other related operations, a certain amount of air will inevitably enter the sewage pipeline. The presence of these air, like a blood clot in the blood vessel, seriously hinders the normal operation of the external transport diaphragm pump, resulting in reduced pump efficiency, unstable operation or even shutdown, which in turn affects the efficiency and stability of the entire sewage transport system.

[0004] Traditionally, in order to solve this problem, operators have to manually dismantle the sewage pipe connection flange to empty it. This method is not only labor-intensive and time-consuming, but also highly dependent on the operator's experience and technical level. The slightest carelessness may cause secondary pollution or equipment damage. More importantly, since the emptying effect is difficult to accurately control, it often leads to incomplete emptying or excessive emptying. The former makes the problem unable to be fundamentally solved, and the latter may cause waste of energy and water resources, increasing operating costs.

[0005] In view of this, it is particularly important to explore a more efficient, convenient and environmentally friendly sewage pipeline emptying technology. The utility model came into being in this context, aiming to provide a solution that can automatically, quickly and effectively empty the air in the sewage pipeline through technological innovation, thereby ensuring the normal operation of equipment such as external transmission diaphragm pumps and improving the overall efficiency and stability of the sewage external transmission system. The utility model can not only significantly reduce the labor intensity of operators, reduce the problem of incomplete or excessive emptying caused by human factors, but also effectively avoid secondary pollution, and contribute to the sustainable development of Yuanba Gas Field and even the entire oil and gas field. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the prior art such as inconvenient exhaust operation in sewage pipelines, high labor intensity, and long time consumption, and to provide an exhaust valve and device for automatically emptying the sewage pipeline. After the utility model is adopted, there is no need for on-duty personnel to enter the site to dismantle the flange for emptying, which greatly reduces the workload and reduces the risks in the operation process. When the air passes through the emptying device, the gas is automatically discharged to ensure the normal operation of the sewage export pump.

[0007] In order to achieve the above-mentioned utility model purpose, the utility model provides the following technical solutions:

[0008] An exhaust valve for realizing automatic emptying of a sewage pipeline, characterized in that it comprises a movable chamber, an exhaust passage, a float, a sealing block and a connecting rod;

[0009] One end of the exhaust channel is connected to the movable chamber, and the other end of the exhaust channel is provided with an exhaust port;

[0010] The connecting rod is arranged in the exhaust channel, passes through the exhaust channel and extends into the movable chamber, and one end of the connecting rod extending into the movable chamber is connected to the float; a sealing block is also arranged on the connecting rod;

[0011] The float is located in the movable compartment, and the float can move up and down in the movable compartment together with the connecting rod;

[0012] The sealing block is located in the exhaust passage. The sealing block can move up and down in the exhaust passage together with the connecting rod. The sealing block can cooperate with the exhaust port to seal the exhaust passage.

[0013] The movable chamber at the bottom of the exhaust valve is used to connect the drainage pipe. When there is air in the pipe, the liquid level in the pipe is low, the float falls, and the exhaust port is opened. The air in the pipe can pass through the exhaust channel and be discharged from the exhaust port. After the air in the pipe is discharged, the liquid level in the pipe rises, driving the float, connecting rod and sealing block to rise together. After the sealing block rises, it blocks the exhaust port, thereby closing the exhaust port, thereby realizing automatic switching of the exhaust port switch.

[0014] Preferably, the connecting rod extends out of the exhaust port, and the connecting rod extending out of the exhaust port is also provided with a top cover, which is used to block foreign matter and prevent the foreign matter from entering the exhaust duct through the exhaust port.

[0015] Preferably, a connecting portion is provided at the bottom of the movable bin, and the connecting portion is used to connect with a pipeline, and the exhaust valve can be connected to a required pipeline through the connection.

[0016] Preferably, the connection part is one of a thread or a buckle. The connection effect of the thread and the buckle is relatively stable and easy to disassemble.

[0017] Preferably, the sealing block is made of rubber material, which has good sealing effect and can easily cooperate with the exhaust port to seal the exhaust port.

[0018] A device for automatically emptying a sewage pipeline, comprising an exhaust valve, an external delivery pump and a pipeline;

[0019] The exhaust valve is the exhaust valve for realizing automatic emptying of the sewage pipeline, and there is at least one exhaust valve; there is at least one external transfer pump; and the pipeline is used to connect the external transfer pump and the exhaust valve.

[0020] Preferably, the external transfer pump is arranged upstream of the exhaust valve.

[0021] The external transfer pump and the exhaust valve are connected by a pipeline. The external transfer pump is arranged upstream of the exhaust valve. The external transfer pump provides power for the sewage in the pipeline and then discharges the air in the pipeline through the exhaust valve.

[0022] Preferably, there are two exhaust valves and two external delivery pumps. Two exhaust valves and external delivery pumps can speed up the discharge of sewage.

[0023] Preferably, it also includes a one-way valve, which is arranged upstream of the external delivery pump and / or downstream of the exhaust valve. The one-way valve prevents sewage from flowing back.

[0024] Preferably, four one-way valves are provided.

[0025] Compared with the prior art, the utility model has the following beneficial effects:

[0026] The utility model protects an exhaust valve for realizing automatic emptying of a sewage pipeline, and automatically controls the opening and closing of an exhaust passage by floating up and down. This design significantly improves the automation level of the equipment, reduces the need for manual intervention, reduces operating costs, and improves the stability and reliability of the system. The exhaust valve has a relatively simple structure, and is mainly composed of a movable bin, an exhaust passage, a float, a sealing block, and a connecting rod. This concise design not only reduces manufacturing costs, but also makes it easier to repair and replace parts of the equipment when a failure occurs, thereby improving maintenance efficiency. Since the floating of the float is automatic according to changes in gas pressure or liquid level, this exhaust valve can adapt to different working environments and working conditions. Whether in a constant pressure environment or in an environment with large pressure fluctuations, it can work effectively to realize automatic emptying of the sewage pipeline.

[0039] Example 1

[0040] This embodiment provides an exhaust valve for automatically emptying a sewage pipeline, including a movable chamber 1, an exhaust channel 2, a float 3, a rubber sealing block 4, a connecting rod 5 and a top cover 6.

[0041] The movable bin 1 is designed to be cylindrical, and a threaded connection portion 11 is provided at the bottom thereof for being tightly connected to a drainage pipe. One end of the exhaust channel 2 is welded to the center of the top of the movable bin 1, and an exhaust port 7 is formed at the other end.

[0042] The connecting rod 5 passes through the exhaust channel 2, one end of which is fixedly connected to the float 3, and the other end passes through the exhaust port 7 and extends to a certain length. The extended part is equipped with a top cover 6 to prevent external foreign matter from entering. The float 3 is designed to be a lightweight material with a certain buoyancy to ensure that it can float freely up and down in the liquid.

[0043] A rubber sealing block 4 is installed on the connecting rod 5, in the part located in the exhaust passage 2. There is a gap between the sealing block 4 and the inner wall of the exhaust passage 2, so that air can pass through. The sealing block 4 can effectively seal or open the exhaust port 7 during the rising or falling process.

[0044] When there is air in the pipeline, the liquid level is low, and the float 3 falls, driving the connecting rod 5 and the sealing block 4 down, thereby opening the exhaust port 7 and allowing the air in the pipeline to be discharged through the exhaust channel 2. As the air is discharged, the liquid level in the pipeline gradually rises, and the float 3 rises accordingly, driving the sealing block 4 up through the connecting rod 5 until the sealing block 4 completely blocks the exhaust port 7, achieving automatic closure.

[0045] The opening and closing of the exhaust channel 2 is automatically controlled by the up and down floating of the float 3. This design significantly improves the automation level of the equipment, reduces the need for manual intervention, reduces operating costs, and improves the stability and reliability of the system. The structure of the exhaust valve 8 is relatively simple, making it easier to repair and replace parts when the equipment fails, improving maintenance efficiency. Since the floating of the float 3 is automatically carried out according to the change of gas pressure or liquid level, this exhaust valve 8 can adapt to different working environments and working conditions. Whether in a constant pressure environment or in an environment with large pressure fluctuations, it can work effectively to achieve automatic emptying of the sewage pipeline.

[0046] Example 2

[0047] This embodiment is expanded on the basis of the embodiment 1, and two exhaust valves 8 and two external transfer pumps 9 are adopted to improve the sewage discharge efficiency and the reliability of the system.

[0048] A device for automatically emptying a sewage pipeline comprises two exhaust valves 8 in the above embodiment, two external delivery pumps 9 and pipes connecting these components. The two exhaust valves 8 are respectively installed on two independent drainage pipes, and each pipe is equipped with an external delivery pump 9.

[0049] The two external transfer pumps 9 are both arranged upstream of their respective exhaust valves 8, and provide power for the sewage through the pipeline, pushing the sewage through the exhaust valve 8 to discharge the air in the pipeline.

[0050] In order to prevent sewage from flowing back in the system, in this embodiment, two one-way valves 10 are installed upstream of the external pump 9 and downstream of the exhaust valve 8 of each pipeline, for a total of four one-way valves 10. These one-way valves 10 ensure that sewage can only flow in one direction, thereby improving the stability and safety of the system.

[0051] Working principle: When the system is running, the two external pumps 9 work simultaneously to provide power for the sewage in their respective pipes. When the sewage flows through the exhaust valve 8, the exhaust valve 8 automatically switches the exhaust port according to the change of the liquid level in the pipe to ensure smooth discharge of air. At the same time, the presence of the one-way valve 10 effectively prevents the backflow of sewage in the system. The entire system greatly improves the sewage discharge speed and the operating efficiency of the system through the configuration of the dual exhaust valves 8 and the dual external pumps 9.

[0052] The above embodiments describe only the basic principles, main features and / or advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the embodiments. The above embodiments and the invention content of the specification only describe the principles or specific cases of the utility model. Without departing from the essence of the innovative idea of ​​the utility model, the innovative scheme of the utility model may also undergo various changes and improvements, and these changes and improvements all fall within the scope of protection required by the utility model.
