Use and selection of electronically controlled hydraulic knife type gate valve
The electric control hydraulic knife type gate valve is also called electro-hydraulic knife-type gate valve, electro-hydraulic knife valve, electro-hydraulic linkage thin gate valve, etc. Its nominal pressure national standard is 0.25MPa, 0.6MPa, 1.0MPa, 1.6MPa, 2.5MPa five. Constant pressure grade, with the recent process requirements, our company has developed a high-pressure electronically controlled hydraulic knife-type gate valve with a pressure of 4.0MPa and 6.4MPa in the reverse sealing packing method. The selection materials of the electronically controlled hydraulic knife type gate valve are WCB (cast steel), stainless steel "target=_blank> stainless steel, alloy steel, etc., electronically controlled hydraulic actuators are explosion-proof and common type; voltage is 380V, 415V, 660V respectively; can be customized according to customer needs with signal conditioning The electric control hydraulic actuator, the sealing valve seat is divided into two kinds of one-way sealing and two-way sealing. The sealing packing is silicone rubber, natural rubber, EPDM rubber, PTFE packing, graphite packing, high pressure medium. Fiber wool fabric is used. The valve body structure is clip-on and flange-type. The distance between the flanges is divided into fixed type and selective type (according to customer needs). The valve plate is made of stainless steel "target=_blank>stainless steel 304 , stainless steel " target=_blank> no Stainless steel 316, stainless steel "target=_blank> stainless steel 321 three. The valve body cavity of Qianfeng Electric Controlled Knife-Type Gate Valve has wear-resistant lining ceramics, corrosion-resistant lining rubber, lining stainless steel "target=_blank> stainless steel, monolithic cast stone, internal cavity carbon spray and other processes.
The electronically controlled hydraulic knife type gate valve is widely used in coal preparation, paper making, metallurgy, environmental protection, pharmaceutical, steel, municipal, sewage treatment, electric power, boiler, petroleum and other industries. The valve body structure of the electronically controlled liquid knife type gate valve is short. The structure is compact, the space is small, the operation mode is flexible and multi-selection, and the medium which cannot be controlled by other valves such as fiber, sand, granule, sludge, crystal and the like can be cut off. The former Feng electric control liquid movable knife type gate valve can be replaced with ordinary electronic control. The hydraulic gate valve is used.
