Gate valves are mainly used for electric power, coal, mining, chemical industry, building materials industry such as cutting material role in the process of conveying. Currently normal gate has the following disadvantages: content of gate valve body sealing parts easy to wear and tear, and then make a gate valve plate switch does not reach the designated position, lead to series of material like now.
Seal gate valves including body, at the side of the valve body is equipped with the valve plate in and out of the hole, decorate in the valve plate in and out of the hole valve plate, the trilateral respectively the inside of the welding of the valve body sealing strip, sealing strip on the plane with the body on the plane coplanar; On one side of the valve plate, roller, on the other side set the wedge surface, in the body with the wedge surface relative welding section for wedge under seal.
Seal gate valve and gate valve for than features are:
On welded to the valve body sealing strip on the surface, so that the body of the sealing strip than existing gate valve seal is more wear-resisting.
The sealing strip is set to wedge shape, body sealing side is set to the wedge shape, so that ensure the valve plate and seal face seal shaped sealing strip.
Seal gate valve gate valve is more than the existing seal, solves the existing gate valve series of material and material leakage.
