进口高温调节阀美国阿卡迪亚品牌

进口高温调节阀Product Description: The purpose is to solve the shortcomings of the current regulating valve that is prone to sealing problems under high temperature, including the valve cover, valve seat and valve body. The regulating valve is provided with a medium channel and a switch channel. The valve cover is inserted with a valve rod, and the valve rod is fixedly connected with a valve core. The valve core slides in the switch channel and adjusts the medium flow speed of the medium channel. The valve core is detachably connected with the valve core upper cover, and the top of the valve core is provided with steps arranged along the circumferential direction, 进口高温调节阀A valve core sealing ring is arranged on the step, the valve core sealing ring is pressed on the upper cover of the valve core, and a valve core guide ring is arranged under the valve core sealing ring. The regulating valve greatly improves the sealing capacity under high temperature through the positioning mode of the valve core sealing ring, and the valve core guide ring is positioned together through the valve core pressing plate, which greatly simplifies the installation steps. characteristic: The valve core sealing ring of the structure is installed and fixed on the valve core with a spiral snap ring. When the valve body is at high temperature, the valve body will undergo certain deformation due to heating, expansion and contraction, which will significantly affect the sealing ability between the valve core and the valve cage. Therefore, the existing valve core sealing method is not conducive to its high-temperature performance. In view of this, there is an urgent need for a method that can still maintain good sealing at high temperature The valve rod is a regulating valve with smooth lifting and high temperature resistance. Principle: 进口高温调节阀The cross section of the upper cover of the valve core is annular, the upper cover of the valve core is provided with a plurality of countersunk holes along the circumferential direction, and the fasteners pass through the countersunk holes to connect the valve core and the upper cover of the valve core, and provide pressing force for the valve core sealing ring and the valve core guide ring. The upper cover of the valve core is fixed on the valve core in the axial direction through fasteners. Compared with the transmission mode, positioning in the side wall direction can better adapt to high-temperature heat rise and have better high-temperature resistance. Each solid part is arranged on the upper cover of the valve core at equal intervals, which can better distribute the stress and avoid stress concentration.
