进口高压差调节阀美国阿卡迪亚品牌

进口高压差调节阀Product Description: The valve cage is a tubular body, three annular protrusions are arranged on the inner wall of the pipe of the valve cage, a through hole is arranged on the inner wall of the pipe at the upper end of the first annular protrusion, and the circumference of the through hole is evenly arranged; The valve core is a cylindrical body, a circle of grooves are arranged at the upper end of the outer side of the valve core column, three pairs of flat grooves are arranged outside the valve core column at the lower end of the groove, the upper and lower pairs of flat grooves are arranged horizontally along the outer side of the vertical body, and the middle pair of flat grooves are arranged longitudinally along the outer side of the vertical body. The valve cage is installed into the valve body, and the valve core is installed into the valve body through the valve cage. When the valve works, the fluid is throttled through the steps of the multi-stage valve core flat groove, so that the fluid with high pressure drop bends and flows along the axis of the valve core.进口高压差调节阀 Through the continuous turning and collision flow of the flow area formed between the valve core and the valve cage, the high pressure difference of the medium decreases continuously along the axis of the valve core, so as to effectively control the pressure drop and flow rate of the fluid and prevent flash and cavitation of the fluid. characteristic: The design principle of labyrinth multistage pressure reducing regulating valve is to stack many annular discs to form a throttling channel through the control valve, and make the annular discs form a fluid path by means of electric corrosion and laser (wire) cutting. The flow path is tortuous, forcing the fluid to throttle and make it pass through the tortuous flow channel, and the fluid plays the purpose of primary pressure reduction every time it passes through a corner. In this process, the kinetic energy of the fluid is consumed, the fluid flow rate is reduced, and the effect of multistage pressure reduction is achieved. However, 进口高压差调节阀for the occasion where the medium is dirty and contains solid particle fluid, if the multi-stage pressure reducing control valve with labyrinth structure is used, due to the narrow groove of labyrinth channel and right angle turning, multiple labyrinth channels are easy to be blocked by solid particle medium, which seriously affects the use effect of multi-stage pressure reducing control valve or completely loses the function of pressure reducing. Principle: When the valve works, the fluid is throttled through the flat groove steps of the multi-stage valve core, so that the fluid with high pressure drop bends and flows along the axis of the valve core. Through the continuous turning and collision flow of the flow area formed between the valve core and the valve cage, the design method of combining radial and axial during fluid flow is adopted, so that the high pressure difference of the medium decreases continuously along the axis of the valve core, so as to effectively control the pressure drop and flow rate of the fluid, Prevent the fluid from flashing and cavitation, and improve the service life of the control valve under harsh working conditions.
