进口气动调节阀是通过气动执行机构控制蒸汽流量的调节阀。工作原理是：当调节手轮旋转时，气动执行机构会带动阀杆移动，改变阀内通过的蒸汽流量，从而实现对蒸汽压力和流量的控制。在此过程中，气源（通常为压缩空气）通过阀体内部的通道流动，影响阀杆的移动，从而达到调节的目的

 The imported pneumatic steam regulating valve is a regulating valve that controls the steam flow rate through a pneumatic actuator. The working principle is that when the handwheel is adjusted to rotate, the pneumatic actuator will drive the valve stem to move, changing the flow rate of steam passing through the valve, thereby achieving control of steam pressure and flow. During this process, the air source (usually compressed air) flows through the channels inside the valve body, affecting the movement of the valve stem, thereby achieving the purpose of regulation

The operating temperature of the valve body material.Pressure range

The 100 Series is a new generation of high performance control valves with self-centering snap-in, non-threaded connection seats. The cage is axially faxed by the bonnet. The vaive cover and the valve body, the vaive seat and the valve body are metal-to-metal contact, and the gap between them is filled by the gasket to ensure sealing. The degree of compression of the bonnet gasket is determined by the pre-tightening force of the bolt on the bonnet. Only the coaxiality between the bonnet and the valive body is ensured, so that the vaive core and the valve seat are perpendicular to the center to facilinate strict Sealing requirements. When the bonnet is fully installed, its force is transmitted to the vaive seat through the cage or sleeve. Only when the height tolerances of the valve seat, cage or sleeve are very close, the gasket of the valve seat is properly compressed to ensure the sealing requirements without causing loakage of the seat gasket by overpressure. If the valve is assembled correctly, it is self-centering; the valve seat of the top guiding structure can be well matched with the valve core without grinding.
