The technical solution adopted for the present invention to solve the technical problems is: the simple and easy water seal valve under a kind of negative pressure feed liquor state, comprise valve gap and valve body, valve body and valve gap are connected with rotatingshaft, rotatingshaft upper end is fixedly connected with the handle matched with rotatingshaft, valve gap upper end is provided with the guiding device for promoting rotatingshaft stability and valve bonnet seal, guiding device is fixedly connected with valve gap upper surface by bolt, guiding device cover is flexibly connected with rotatingshaft on the rotating shaft, bonnet lower surface central position is provided with annular for lift-off seal performance to lower convexity, the corresponding annular protrusion position of valve body upper surface offers stepped recess, valve body upper end is provided with the valve bucket that inner diameter is greater than valve gap outer diameter, valve bucket upward opening, valve bucket lower surface offers the axis hole matched with rotatingshaft, shaft hole diameter is greater than protruding diameter, valve bucket is arranged between valve body and valve gap, valve bucket, be bolted fixing between valve body and valve gap, valve bucket outer side wall is fixedly connected with boiler alarm, the nearly lower end position of valve bucket madial wall is fixedly connected with the level sensor be electrically connected with boiler alarm.
Further, boiler alarm is made up of shell, loudspeaker and power supply unit.
Further, height of projection is less than valve bucket bottom thickness.
Further, valve bucket is highly greater than the height of valve gap.
Further, valve bucket inner bottom surface and outer bottom are provided with the waterproof sealing layer for lift-off seal.
The invention has the beneficial effects as follows, simple and easy water seal valve under negative pressure feed liquor state of the present invention carrys out the valve bucket of poppet sealing by being provided with contain fluid between valve gap and valve body, and automatic water level alarm set is set on valve bucket, by with surface tension of liquid, not only thoroughly stop the gas leak phenomenon of ecto-entad under negative pressure state, prompting can also be sent in time, the Security of further poppet when valve inner bucket water position is too low.
