Description

Technical Field

[0001] The present invention relates to the technical field of exhaust valves, and in particular to an exhaust valve with a pressure monitoring function. Background Art

[0002] Exhaust valves are widely used in the pump and valve industry for pipeline exhaust. The exhaust valves used on traditional pumps and valves have a relatively simple structure and are installed by installing a port on the corresponding pipeline of the pump and valve.

[0003] Existing valve pressure detection devices generally simply add a pressure gauge. For example, the existing patent CN201921396355.1 discloses a valve with a pressure detection feedback function, including a valve body shell, a water pressure sensor, a spring, a slider and a limit rod. When the water pressure is too low, the device performs auxiliary detection on the water pressure, and when the water pressure is insufficient, no water flows out when the valve is opened, and the water pressure condition is directly fed back. If the water pressure is too low, no output is performed to protect external demand equipment.

[0004] However, the above technical solution is not convenient for disassembly and maintenance when the pressure detection module in the valve needs to be replaced or maintained after being used for a long time, and it is also unable to reduce the impact of water flow when there is no need to detect the pressure in the valve, which may affect the detection accuracy of the pressure sensor and reduce the service life of the pressure sensor. In addition, the existing exhaust valve is not stable enough during installation, which may cause displacement during installation, thus affecting the installation.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention
