The invention discloses a blow-down valve used for chemical production, and relates to the technical field of chemical valves. The blow-down valve used for chemical production comprises a valve body,a clamping device located outside the valve body, an adjustment device located in an inner cavity of the valve body, and a pressing device arranged above the valve body. The two sides of the valve body are fixedly sleeved with limiting sleeve plates. The left side of the valve body is fixedly sleeved with the clamping device. According to the blow-down valve used for chemical production, positioning rods and fastening devices are used in cooperation so that the structures of the valve can be connected more tightly; when the valve is blocked, the problem that bolts of the valve are rusted and cannot be disassembled easily after long-time use can be effectively solved, the maintenance convenience of the valve is effectively improved, and the service life of the valve is prolonged; and bearing sleeve plates are arranged in the valve body and between the limiting sleeve plates and connecting sleeves, so that the valve body is sealed, and the problem that an existing valve is prone to waterseepage is solved.
Description
technical field [0001] The invention relates to the technical field of chemical valves, in particular to a sewage valve for chemical production. Background technique [0002] The valve is a pipeline accessory used to open and close the pipeline, control the flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium, and the valve is a control component in the fluid conveying system, with cut-off, adjustment, diversion, Functions such as preventing backflow, stabilizing pressure, shunting or overflowing and pressure relief, especially with the rapid development of modern industry, the demand for valves is constantly increasing, so it is necessary to study them. [0003] Most of the existing valves use a screw to control the opening and closing of the valve. After a long time of use, the screw inside the valve is prone to rust and damage, and the water control part of the valve is not in close contact, resulting in water leakage ...
