Description

Technical Field

[0001] The utility model relates to the technical field of safety valves, in particular to a safety valve with a filtering device. Background Art

[0002] The safety valve is a special valve that is normally closed under the action of external force. When the medium pressure in the equipment or pipeline exceeds the specified value, the medium is discharged to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value. Due to the poor water quality in the system containing a large amount of impurities such as mud and sand, after the safety valve is actuated, the sealing system is blocked by impurities, and the safety valve cannot be closed normally, thereby continuously leaking water. In order to avoid blockage of the safety valve, a filter device is generally installed at the front end of the safety valve, but the existing filter device has certain inconveniences when used.

[0003] A low-temperature safety valve with a filtering device is disclosed in the Chinese utility model patent application number: CN202120177293.6. The setting of the filter plate can achieve filtering effect and extend the service life, and an electric push rod is set. Most of the valves are manually operated with a switch, and the electric push rod is used to adjust the valve, which effectively saves human resources. However, the filtering device of the safety valve cannot automatically clean the filtered impurities during use, and the long-term accumulation of impurities will also affect the use of the safety valve. In addition, the filtering device of the safety valve is not convenient for removing the filtered impurities during use, which is easy to affect the working efficiency of the installed valve. For this reason, we propose a safety valve with a filtering device. Utility Model Content
