Using above-mentioned technical proposal, the first valve deck and the second valve deck that bonnet assemblies are arranged to be separately set, the first valve
Lid one end is connected with valve body, other end connection valve deck protection component.
A kind of above-mentioned novel top-mounted ball valve can be further arranged to：The valve rod protection component includes and the first valve deck
The first protection board abutted against, the one end of the valve rod away from valve body are equipped with the second protection board, the first protection board both sides point
Valve rod protection valve is not equipped with, and the valve rod protection valve other end is connected to the second protection board.
Using above-mentioned technical proposal, valve rod protection component includes the first protection board and the second protection board, in the first protection
Plate and the valve rod protection valve of the second protection board both sides connection can play the protective effect to valve rod and the first valve rod junction.
A kind of above-mentioned novel top-mounted ball valve can be further arranged to：The valve rod is equipped with connector sleeve, first valve
Lid and the first protection board are rotatably connected on connector sleeve respectively, and one end outer circumferential surface of the connector sleeve away from the first valve deck is equipped with support
Block, second valve deck are connected at supporting block and abutting and are equipped with supporting block-shaped consistent groove.
Using above-mentioned technical proposal, the first valve deck and the first protection board are rotatably connected on connector sleeve respectively by connector sleeve,
In the supporting block that the other end of connector sleeve is set together with the second valve deck abutting, the second valve deck is provided with and props up at supporting block
The groove that bracer is adapted towards shape at the second valve deck, the connection for being consolidated the second valve deck by the cooperation of groove and supporting block
At this.
A kind of above-mentioned novel top-mounted ball valve can be further arranged to：Second valve deck is equipped with the opposite connection set up
Hole, first protection board and the first valve deck are equipped with the threaded hole consistent with connection hole shape in connecting hole opposite position.
A kind of above-mentioned novel top-mounted ball valve can be further arranged to：The described one end of second valve deck away from the first protection board
Equipped with the connection bolt that the second valve deck, the first protection board and the first valve deck link together.
