Description

Technical Field

[0001] The invention relates to the technical field of automatic valve quick docking, in particular to an automatic valve with quick docking sealing warning. Background Art

[0002] When the automatic valve is in use, the electronic control equipment is set to effectively control the opening and closing of the valve, thereby improving the stability of material flow and controlling the material delivery to different locations. The quick docking mechanism set on the automatic valve can improve the convenience between the automatic valve and the pipeline. However, during use, the docking position is prone to leakage, which can easily affect the stability of material delivery.

[0003] In order to overcome the above-mentioned defects, the prior art (application number CN202322097130.9, Chinese patent application with application date 2023-08-07) is an electric valve with leakage detection. The leakage sensor connection line is movably stuck on the wire support frame on the outer surface of the sensor opener and closeer, which has a wire management function. The annular opening arc with insulating performance has a certain anti-slip property, which can avoid the failure of contact sensitivity caused by a large arc of sagging of the wiring, effectively improve the protectiveness of the wiring installation, and operate the pressure piece after the electronic component fails. Under the active characteristics of the elastic part, the upper working state of the power contact rod is changed to the downward power-off state, so that the connection board loses power, and the red light of the power supply part goes out, indicating that the leakage sensor The sensing component stops working, while other sensing modules in the electric control box do not stop working. Under the condition of sharing a battery power supply, the leakage sensing component can be repaired separately, which can quickly improve the maintenance efficiency of accessories and effectively improve the performance of the electric valve. There is also a prior art (Chinese patent application with application number CN202411861735.3 and application date of 2024-12-17) a stop valve with automatic alarm function, which monitors the leakage signal by installing an alarm mechanism on the stop valve and setting a plurality of detection rods at the connection surface of the stop valve and the pipeline according to an equidistant array. When natural gas leaks from the connection surface, on the one hand, the connection surface will emit an airflow sound to form a first noise, and the airflow Acting on any detection rod to generate vibration to form a second noise, the first noise and the second noise collected are amplified by the microphone inside the detection rod, so that the noise sensor can receive the amplified sound more sensitively and accurately and alarm, further improving the sensitivity of the alarm mechanism; and the prior art (application number CN202022511793.7, Chinese patent application date 2020-10-26) a pressure reducing valve with an alarm structure, provided with a docking flange, an L-shaped pipe, a pressure transmitter, a receiver, an alarm and a controller. First, a suitable pressure transmitter is selected. The pressure transmitter is a device that converts pressure into an electric signal for control and remote transmission. It can measure pressure. The physical pressure parameters of gas, liquid, etc. sensed by the component sensor are converted into standard electrical signals. When the pressure inside the pressure reducing valve body changes too much, the pressure transmitter transmits the signal to the receiver, and the receiver transmits the signal to the controller. The controller controls the alarm to flash and beep, thereby warning the operator. Although the existing technology can complete docking and leakage detection, during the working process, an independent leakage warning device is required to detect the position of the quick connector, which is easy to affect the stability of the seal and easily cause inaccurate detection. When a leak occurs, it is difficult to seal and warn in time, affecting the use of sealing and warning effects, and when pressure relief occurs in the transportation of solid materials, it is difficult to find the blockage in time.
