Embodiment Construction
[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0041] At present, the air valve cannot feedback the real-time status of the valve being fully open or fully closed, nor can it feedback whether the valve is in a state of slight exhaust and whether the main seal is leaking, which affects the stability of the air valve. Therefore, the inventors of the present application provide the following embodiments to solve the above problems.
[0042] Please refer to Figure 1-3 , this embodiment provides an air valve with signal transmission, which is used for removing air. The air valve includes a valve body 1, an inner core 2 movably installed in the valve body 1, a valve cover 3 fixedly installed on the valve body 1 and a...

The invention discloses an air valve with a signal transmission function. The air valve comprises a valve body, an inner core, a valve cover, a mounting structure, a signal transmitting device and a signal feedback mechanism, wherein the mounting structure comprises four groups of supporting columns, a protective cover and a protective net. The signal feedback mechanism comprises a support, two sets of proximity switches, a stroke contact block installed in the support in a sliding mode, a stroke rod fixedly installed on the stroke contact block, a piezoresistive pressure transmitter and a liquid level proximity switch; the two sets of proximity switches are used for feeding back that the air valve is in a valve closing state and a valve opening state respectively; the piezoresistive pressure transmitter is used for feeding back that the air valve is in a trace exhaust state; and the liquid level proximity switch is used for feeding back that the air valve is in a main seal leakage state. The air valve provided by the invention has the valve opening state feedback function, the valve closing state feedback function, the trace exhaust starting feedback function and the main seal leakage feedback function, the working state of the air valve can be mastered conveniently, and the use stability is guaranteed.
Description
technical field [0001] The invention relates to the field of valves, in particular to an air valve with signal transmission. Background technique [0002] The air valve is a special valve used to prevent the negative pressure in the pipe caused by the decompression wave in the transient process. It is usually installed when the dynamic water pressure is low during the normal operation of the pipeline, and liquid column separation may occur during the transient flow process. When the pressure in the pipeline is lower than the atmospheric pressure, the air is sucked in, and when the pressure in the pipeline rises above the atmospheric pressure, the air is discharged. During the exhaust process, when the liquid in the pipe is full of the pipe, the valve can be closed automatically, and the liquid is not allowed to leak into the atmosphere. The operation of the pipeline is safe. [0003] When filling the pipe with water, the faster the gas in the pipe is discharged, the faster...
