Description
Technical Field
The utility model belongs to the technical field of valve clack grinding, and relates to a valve clack grinding device.
Background
The double-flap check valve is a valve which automatically opens and closes a flap by means of the flow of a medium and is used for preventing the medium from flowing backwards, and is also called a check valve, a one-way valve, a reverse flow valve and a back pressure valve. The automatic valve is mainly used for preventing medium from flowing backwards, preventing the reverse rotation of a pump and a driving motor, and is a double-flap check valve and discharging the medium in a container. The function of the double-flap check valve is to allow the medium to flow in one direction only; the flaps of the two-flap check valve open under fluid pressure and fluid flows from the inlet side to the outlet side. When the pressure of the inlet side is lower than that of the outlet side, the valve clack is automatically closed under the action of the factors of fluid pressure difference, self gravity and the like so as to prevent the fluid from flowing backwards. Therefore, the double-flap check valve is required to have extremely high sealing performance, and the manual grinding efficiency of the sealing surface of the valve flap is low, so that the grinding direction, the grinding speed and the grinding force are difficult to master, the precision of the ground product is low, the sealing surface of the valve seat in the valve body is more difficult to reach the ideal precision, and the leakage phenomenon can occur at the sealing position of the valve. Based on this, we design a valve clack grinding device
