The use of hydraulic control valve, we must first pay attention to selection. Improper selection will cause water blocking and air leakage. When selecting the hydraulic control valve, the displacement of the hydraulic control valve must be selected in accordance with the steam consumption per hour of the device multiplied by the selection magnification of 2-3 times the maximum amount of condensate. In order to ensure that the hydraulic control valve can discharge condensate as soon as possible while driving, the temperature of the heating equipment can be rapidly increased. The lack of energy discharged by the hydraulic control valve will cause the condensate to be discharged in time and reduce the thermal efficiency of the heating equipment.
When selecting a hydraulic control valve, the hydraulic control valve cannot be selected by nominal pressure, because the nominal pressure can only indicate the pressure level of the body of the hydraulic control valve, and the nominal pressure of the hydraulic control valve greatly differs from the working pressure. Therefore, it is necessary to select the displacement of the hydraulic control valve according to the working pressure difference. The working pressure difference is the working pressure before the hydraulic control valve minus the back pressure at the outlet of the hydraulic control valve. Selecting the hydraulic control valve requires accurate steam and water resistance, high sensitivity, improved steam utilization, no leakage of steam, reliable working performance, high back pressure, long service life, and easy maintenance.
The hydraulic control valve is a water pressure controlled valve. It consists of a main valve and its attached conduit, pilot valve, needle valve, ball valve and pressure gauge.
Hexagonal Steel Plate Mesh is developed from the expanded steel diamond mesh, whose mold has evolved. When we produce the hexagonal steel expanded plate mesh, we have to choose the strong toughness of metal plate because the angle between hypotenuse and the straight edge is too larger. But it is just because of this structure, the hexagonal stainless steel expanded metal lath has the property of diamond expanded metal mesh, meanwhile itself has: toughness, strong impact resistance, strong structure, beautiful appearance and other characteristics.
Material: Tough carbon steel plate, aluminum plate, stainless steel plate, aluminum magnesium alloy plate, copper plate, nickel plate and other plates customers need.
Specification: Thickness of plate: 0.8mm-6mm, short way of opening: 10-60mm, long way of opening 2-120mm. The width and length of plate is according to customers` requirements.
Use: Hexagonal steel expanded mesh is used in various fields, such as workshops, ships, ceilings, floors, walkways, pedals, trench covers, sides of the conveyor, fences, etc..
