Manual hidden rod type knife gate valve has the advantages of simple and compact structure, reasonable design, light material saving, reliable sealing, flexible operation, small volume, smooth channel, small flow resistance, light weight, easy installation, easy disassembly and other advantages, can be in 1.0MPa-2.5MPa working pressure, working temperature of -29-550 DEG C under normal use.

     Knife gate valve: suitable for general petrochemical industry, cement paper powder, the environmental protection industry and other categories of slurry fluid. Manual hidden rod type knife gate valve of the gate with the shear function, can scrape the surface of the adhesive seal material, automatically remove debris, stainless steel gate to prevent leakage caused by corrosion.

    Knife gate valveProduct features 1, short length of the structure can make the pipeline, material saving, the whole system greatly reduce the weight of 2, small occupied space, can effectively support the pipeline strength, can reduce the possibility of pipeline vibration, the 3 gate selection of austenitic stainless steel, corrosion resistant performance is greatly improved, which can effectively prevent the seal packing seal and gate corrosion by 4, the leakage of flexible PTFE, reliable sealing, flexible operation, the 5 gate with the knife, can effectively brake off all kinds of debris in the medium

A,Hand operated lever type knife gate valveIt belongs to the valve technology field. The problem to be solved is to provide a gas knife gate valve with short structure, small size, reliable sealing and long service life. Includes valve body, valve cover, valve gate, and a transmission mechanism, its characteristics, structure, and the valve body is connected with the pipeline plane plate on the clamp gate using single gate, and one side of the body seat sealing, wedge contact between the other side of the back and the valve body, flow relative to the surface and sealing medium. The wedge contact structure is that the back surface of the sealing surface is provided with a wedge pressing block, and the other side of the valve body is provided with the adjusting top wire at the pressing block. The utility model has the advantages of short length of the valve body, light weight, the sealing surface of the valve seat can be avoided from the medium flushing, the sealing surface is pressed uniformly, the joint is tight, and the dust, tar, etc. on the sealing surface of the valve seat can be scraped away in the closing process, and the sewage discharge is convenient. Suitable for use in gas pipelines containing dust or tar.
