Description

TECHNICAL FIELD

[0001] The application relates to the technical field of pipeline accessory fittings, and particularly relates to a valve state rapid detection device. BACKGROUND

[0002] As a key component in a pipeline system, a valve is widely used in various industrial environments, especially in factory pipeline management, and its importance is self-evident. The main functions of the valve include opening and closing a pipeline, controlling the flow direction of a fluid, adjusting the flow of a conveying medium, and the like, so as to realize accurate control of fluid flow. Each valve at least has two basic states of opening and closing, and the switching of the states is realized through the movement of a rotating part inside the valve.

[0003] In a complex factory pipeline system, since the types and flow directions of the fluids in the pipelines are different, in order to ensure the safety and flexibility of the pipeline system, a valve needs to be separately arranged for each pipeline, so as to independently control and manage each pipeline. However, with the continuous expansion and complication of the factory pipeline system, the number of valves increases sharply, which undoubtedly brings great challenges to the daily management and maintenance of the factory.

[0004] The traditional valve state detection method mainly depends on the visual inspection of an inspector. The inspector needs to check the opening and closing states of each valve one by one, so as to ensure the normal operation of the pipeline system. Since the number of pipelines and valves in the factory is large and widely distributed, the inspector is difficult to complete the inspection of all the valves in a short time. The opening and closing states of the valves are not always easy to directly observe, especially when the valve is located in a difficult-to-access position or in a complex environment, the inspector is difficult to accurately judge the actual state of the valve.

[0005] Therefore, the application provides a valve state rapid detection device to solve the above problems. CONTENT OF THE UTILITY MODEL

[0013] Preferably, in order to prevent leakage at the connection between the valve body and the detection tube, a sealing ring is arranged on the detection tube to seal the gap between the detection tube and the valve body. The sealing ring is made of rubber material with wear resistance and corrosion resistance.

[0014] Preferably, a detector is arranged on the valve core in the valve body, a scale sensor is installed on the valve rod of the valve body, a display screen is arranged on the valve body and connected with the scale sensor, and a timer is also arranged on the valve body and connected with the display screen.

[0015] The application can display the opening and closing state of the valve in real time and intuitively through the bright and dark state of the LED lamp, and avoid the tedious and error of manual visual inspection. The valve state monitoring can be automatically completed without manual intervention, and the management efficiency and safety are improved. The application is suitable for various types and sizes of valves, and pipeline systems with different fluid media and flow rates.

[0016] The application measures the time required for the valve to rotate one degree scale during 360-degree rotation, to determine whether the valve rotation is stuck, the rotation linearity is smooth, and other performance states. When measuring whether the working state of any valve is good, the detector can be installed on the valve core.

Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0024] The embodiment provides a valve state rapid detection device, as shown in Figures 1-4 , the detection device comprises a valve body 1 and a detection structure 2 for detecting the opening and closing state of the valve body 1.

[0025] The detection structure 2 comprises a detection pipe 21 fixedly installed at the output end of the valve body 1, a generator 22 fixedly installed on the detection pipe 21, a rotating shaft 23 rotatably inserted into the detection pipe 21 and connected with the output end of the generator 22, an impeller 24 fixedly sleeved on the rotating shaft 23, and an LED lamp 25 electrically connected with the generator 22. The opening and closing state of the valve can be displayed in real time and intuitively through the bright and dark state of the LED lamp 25, avoiding the tediousness and error of manual visual inspection. The valve state monitoring can be automatically completed without manual intervention, improving the management efficiency and safety. It is suitable for various types and sizes of valves and pipeline systems with different fluid media and flow rates. The mechanical energy generated by fluid flow is used to generate electricity without external power supply, realizing the recycling of energy and energy saving and emission reduction. When the valve is in the open state, the fluid enters the inside of the detection pipe 21 through the valve body 1, impinges and drives the impeller 24 to rotate. The rotation of the impeller 24 is transmitted to the shaft of the generator 22 through the rotating shaft 23, so that the generator 22 starts to generate electricity. The electric energy is transmitted to the LED lamp 25 through the wire, so that the LED lamp 25 is bright, indicating that the valve is in the open state. When the valve is closed, the fluid flow is cut off, and the impeller 24 stops rotating. The generator 22 stops generating electricity due to lack of power input, and the LED lamp 25 is extinguished, indicating that the valve is in the closed state.

[0026] In order to facilitate the installation of the generator 22, a plurality of through-hole plates 221 are fixedly connected in an annular array near one end of the generator 22, and the through-hole plates 221 are fixedly installed on the detection pipe 21 by bolts. Through the installation mode of the bolts, the generator 22 is convenient to install or disassemble and maintain.

[0027] In order to facilitate the installation of the LED lamp 25, a lamp holder 222 is fixedly installed on the generator 22 and electrically connected with the generator 22, and the LED lamp 25 is threadedly inserted into the lamp holder 222. Through the threaded connection mode, the LED lamp 25 is convenient to install or disassemble.

[0028] The two ends of the detection pipe 21 are in the shape of a tapered pipe. Through the tapered pipe-shaped detection pipe 21, the flow rate of the liquid entering the detection pipe 21 from the valve can be accelerated.

[0029] The two ends of the valve body 1 are fixedly sleeved with first flanges 11, and the two ends of the detection pipe 21 are fixedly sleeved with second flanges 211, wherein the opposite first flanges 11 and second flanges 211 are fixedly connected by bolts.

[0030] The detection pipe 21 is provided with a sealing ring 3 for sealing the gap between the detection pipe 21 and the valve body 1. The sealing ring 3 is made of rubber material which is wear-resistant and corrosion-resistant.

[0031] The detector 4 is arranged on the valve core in the valve body 1, the scale sensor 41 is installed on the valve stem of the valve body 1, the display screen 42 is arranged on the valve body 1 and connected with the scale sensor 41, and the timer 43 is also arranged on the valve body 1 and connected with the display screen 42. When the working state of any valve is to be measured, the detector 4 is arranged on the valve core, the time required by the valve core in rotating through each 1 degree angle is measured through the timer 43 and the scale sensor 41, and the measurement record can be viewed through the display screen 42, so as to judge the performance state of the valve. The time required by the valve in rotating through each 1 degree scale in the 360 degree rotation is measured, so as to judge whether the valve rotation exists stagnation, whether the rotation linearity is smooth and other performance states.
