Main uses of Semir products

This product uses an electro-hydraulic linkage device to control the opening and closing of valves through reciprocating pushing. If equipped with sensors or digital display devices, it can be centrally or program-controlled in remote and high-altitude dangerous areas. It is widely used in oil, water, and steam pipelines such as food, paper, medicine, petroleum, and chemical industries to connect or cut off fibers, dust, chemical treatment wastewater, sedimentation tanks, asphalt, silo outlets, fruit juice, grains, and other media in the pipelines.

Characteristics, description, and working principle of Semir products

Hydraulic knife gate valve, also known as hydraulic knife type gate valve, is connected to the valve gate by a hydraulic cylinder piston rod. Its operating principle is to manually drive the hydraulic pump handle to press hydraulic oil into the upper and lower chambers of the hydraulic cylinder through a manual directional valve, which drives the piston rod to move up and down, thereby driving the opening and closing of the gate plate to achieve the valve opening and closing function.

PZ273Y electro-hydraulic knife gate valve is an integral knife gate valve structure, which includes a valve body, a gate plate, and a U-shaped sealing strip. The bottom of the chamber in the valve body is provided with a groove and an elastic U-shaped sealing strip. When the valve is closed, the gate plate moves downward, and the bottom edge of the gate plate contacts the sealing strip, compressing the sealing strip into the groove to achieve sealing between the valve body and the gate plate; When the knife gate valve is opened, the gate moves upward and the bottom edge of the gate disengages from the sealing strip. The sealing strip bounces up and the groove is flat, which can prevent the medium sediment from accumulating in the groove of the valve body during use, making it difficult to block and residue free. The pipeline is easy to clean, effectively improving the sealing effect of the knife gate valve and preventing leakage when the valve is closed. Longer service life, simpler maintenance, flange sealing surface with O-ring, no need for additional flange gasket, simple and convenient installation, low friction coefficient, flexible opening and closing.

Application scope and fields of Semir products

Knife gate valve, also known as knife gate valve or knife gate valve, is suitable for pipelines containing suspended particles and fiber materials such as pulp, sewage, coal slurry, ash and cement mixtures. It is cut off by a blade shaped gate that can cut through fiber materials. The valve body actually does not have a chamber, and the gate plate rises and falls in the side guide groove, and is tightly pressed against the valve seat by the bottom protrusion. If high medium sealing performance is required, an O-shaped sealing valve seat can be used to achieve bidirectional sealing. According to the driving mode, it is divided into manual knife gate valve, pneumatic knife gate valve, and electric knife gate valve.

Knife gate valves are suitable for coal preparation, ash discharge, slag discharge, urban sewage treatment, food, sanitation, medicine and other pipeline systems in mining power plants. The ultra-thin knife gate valve solves the difficult problems of high flow resistance, heavy weight, difficult installation, and large footprint of ordinary gate valves, flat gate valves, ball valves, globe valves, regulating valves, butterfly valves, and other types of valves due to its advantages of small volume, low flow resistance, light weight, easy installation, and easy disassembly. After the emergence of knife gate valves, a large number of general-purpose cut-off valves and regulating valves have been replaced by them. Until now, the United States and Japan have the largest usage of knife gate valves.
