Pilot valve with its small size, compact structure, good sealing effect, high cutting capacity (up to the nominal pressure), a wide range of applications and long life and other characteristics of the automatic control system has been more and more widely used. The valve can be used as a blow-off valve, especially for high temperature, high pressure and large diameter cut off the occasion. The pilot-operated control valve has a top-down flow structure and a separate pressure-balanced pilot valve. As the valve closes, pressure builds back pressure through the gap between the main valve and the sleeve, Sealing, when the pilot valve flap and the main valve to meet the required pressure, the higher the media pressure, the more tight the valve seal. When you want to open the valve, let the actuator lift the valve stem, first open the pilot valve, as the pilot valve flap on the main valve flap and sleeve gap greater mobility, the main valve flap to balance, so as to compare Small force opens the main valve flap. Pilot valve design in addition to the valve to consider the closure of the valve performance, but also consider the stability of the valve performance and regulatory performance. Pilot valve seat valve passage to meet the flow capacity greater than the guide ring and the main valve flap and sleeve gap flow capacity and its open degree of opening control in the valve opening of 10% or less, otherwise it will have a valve open or small Flow range can not be adjusted. Spring design principles to meet the stiffness of the spring to resist medium pressure fluctuations, or in the pilot valve flap and the main valve will produce vibration and other issues. The main function of the guide ring is to increase the stability of the valve disc assembly and to limit the problem that the clearance between the main valve flap and the sleeve due to temperature causes a large gap between the circulation capacity and the pilot valve seat channel flow capacity. The function of the stop pin is to control the rotation tendency of the pilot valve flap and the main valve flap due to the vortex flow. The spring controls the tendency of the pilot valve flap and the main valve flap to vibrate up and down.
