Specific embodiment
1 to Fig. 5 knife gate valve embodiment for being used to convey mud a kind of to the utility model is done further in detail referring to the drawings
Explanation.
A kind of knife gate valve for being used to convey mud, including valve body 1, valve rod 2 and flashboard 3, the valve body 1 is installed with mutually
Mounting hole 11 and runner 12 are connected, valve deck 4 is equipped in the top of valve body 1, the valve deck 4 forms pressure cavities with valve body 1；Pacifying
It fills hole 11 and is equipped with valve component 5, the valve component 5 includes two symmetrical valve seats 51, and the flashboard 3 is placed in two
Between valve seat 51, the wherein end face of valve seat 51 and flashboard 3 is inconsistent, and other end and the side wall of mounting hole 11 are inconsistent, shape
Into first of sealing, first of sealing, which effective can avoid the impurity in fluid media (medium) from entering pressure cavities, influences knife gate valve
Normal operation, while also fluid medium plays the role of pressure buffer, when fluid media (medium) enters pressure cavities, pressure is empty at this time
