Description
Technical Field
The application belongs to the field of fluid power and pipeline cleaning, and particularly relates to a fluid pipeline locking unit and a fluid pipeline cleaning device comprising the same.
Background
In the field of fluid dynamics, particularly in the technical fields of transmission such as hydraulic pressure and air pressure, along with the continuous improvement of application requirements, high requirements are not only provided for the cleanliness of pumps, cylinder bodies, valves, motors, working media, working medium containers and the like, but also new requirements are provided for the cleanliness of fluid pipelines. Thus, a device for cleaning the contaminated fluid line is produced.
At present, the cleaning methods for fluid pipelines mainly include the following methods, for example: ultrasonic cleaning, wire brush cleaning, oil or chemical solvent cleaning, high pressure water jet flushing, or air flow blowing, etc. The ultrasonic cleaning has a good cleaning effect on the inner wall of the straight pipeline, but has a poor cleaning effect on the inner wall of the bent pipeline; when oil or chemical solvent is used for cleaning, oil stain or chemical residue can be remained in the fluid pipeline, and the environment can be polluted; when high-pressure water jet is adopted for washing, the cleaning effect on shorter pipelines is better, but the cleaning effect on longer pipelines is still poor; when the air flow is adopted for blowing and washing, although the high-pressure air flow can be utilized for quickly washing the pipeline, the effect of washing the fibrous particles adhered to the pipe wall or the joint of the pipeline and the rust in the field prepared pipeline is poor, and even if washing balls or sponges are used in the air flow, the washing effect is extremely limited, so that the requirement on cleanness is difficult to meet.
The existing fluid pipeline cleaning device has the advantages that the cleaning of the pipe wall is realized by controlling flushing liquid flow or air flow through a pulse valve, the control of flushing fluid is also realized by using an electromagnetic directional valve, the cost of the components is high, frequent switching is needed during the cleaning working condition, the service life is greatly influenced, the use cost and the maintenance cost are potentially increased, and the reliability and the stability of the fluid pipeline cleaning device using the valves are reduced. In addition, switching valves including pulse valve control, solenoid directional valves, etc. require manual operation or system control, which seriously affects the responsiveness and performance of the pipeline cleaning device. Moreover, if a plurality of such switching valves are used in the system, the coordination capability and the self-adaptation capability of the system are greatly reduced.
Due to limitations of use, installation and other requirements (for example, limitations in terms of pressure-bearing capacity, flow rate, positions of connecting ends and the like), fluid pipelines are various in types, for example, the fluid pipelines are divided into hoses (for example, rubber hoses, resin hoses and the like) and hard pipes (for example, cold drawn pipes, steel pipes, copper pipes and the like), the thicknesses of the fluid pipelines and the types of joints are different, and particularly for the hard pipes such as the steel pipes and the like, it is difficult to find universal cleaning devices to clean different pipelines. In terms of fluid pipelines, in most cases, the fluid pipelines need to be bent due to the limitation of spatial arrangement, and the cleaning difficulty of the pipelines is high, so that the existing pipeline cleaning device can not be applied to the pipelines.
In addition, in the process of cleaning the pipeline, a cleaning strategy is determined according to the pollution degree of the cleaned pipeline and the difficulty degree of cleaning the pollutants, the cleaning strategy of the traditional cleaning device has no objective basis, so that corresponding judgment can be carried out only by depending on the working experience of an operator, the formulated cleaning strategy is natural and unscientific, and the problems of labor waste, time waste, serious loss and the like caused by overlong cleaning time and the problems of unclean cleaning, incomplete cleaning and the like caused by overlong cleaning time are caused.
In the cleaning process of a fluid pipeline, one end of a cleaned pipeline needs to be connected with a fluid pipeline cleaning device, the traditional method is that a plurality of threaded interfaces and flange interfaces are arranged on the pipeline cleaning device, and when the fluid pipeline is cleaned, different cleaned pipelines are hermetically connected with the corresponding threaded interfaces and flange interfaces of the fluid pipeline; after the connection, cleaning the pipeline; after the cleaning, the cleaned pipeline is detached. In specific implementation, limited by space and design, the traditional fluid pipeline cleaning device is difficult to adapt to various different cleaned pipelines, the time for connecting and disassembling the cleaned pipelines is almost similar to the pipeline cleaning time, and the traditional fluid pipeline cleaning device is difficult to adapt to efficient and rapid cleaning of large-batch pipelines; in addition, after multiple uses, irreparable damage can be caused to the interface of the fluid pipeline. Therefore, an improvement of the fluid line locking unit of the fluid line cleaning apparatus is imperative.
Therefore, it is urgently needed to invent a fluid pipeline locking unit which can simultaneously meet the adaptation of fluid pipelines with different pipe diameters and different joints, can effectively improve the connection convenience and the disassembly and assembly efficiency of the cleaned pipeline, and can not damage the outer wall of the cleaned pipeline, and the fluid pipeline cleaning device which has the advantages of high cleaning efficiency, scientific cleaning strategy, good responsiveness, long service life, safe and reliable system and the like.
