The invention discloses a swing type control valve. The swing type control valve comprises a swing reversing mechanism and a valve body sealing cover which are arranged in a mounting cavity, wherein the valve body sealing cover is arranged at the air outlet end of a valve body; the swing reversing mechanism comprises a speed reduction steering gear set; an input shaft of the speed reduction steering gear set is connected with a driving mechanism; an output shaft of the speed reduction steering gear set is in transmission connection with the valve body sealing cover and drives the valve body sealing cover to be opened and closed; a pilot pressure relief hole is formed in the valve body sealing cover; a pilot sealing cover matched with the pilot pressure relief hole is arranged on the valve body sealing cover; and when the control valve is opened, the swing reversing mechanism firstly opens the pilot sealing cover and then opens the valve body sealing cover. According to the swing type control valve, the valve body sealing cover can be quickly opened and closed, and a sealing surface of the valve body sealing cover and a valve body sealing opening are free of friction in the opening and closing process, so that the circumstance of damage of the sealing surface, leakage and venting are reduced, and the service life of the valve is prolonged; and pilot pressure relief is carried out through the pilot sealing cover, so that the torque required during opening is reduced, and the explosion-proof safety of a product is improved.
Description
technical field [0001] The invention relates to the technical field of metering control, in particular to a swing control valve. Background technique [0002] As people pay more attention to environmental protection issues and the continuous improvement of environmental protection awareness, natural gas as an emerging environmentally friendly energy source has received more and more attention and use. Control becomes an important issue. The special control valve for intelligent controller takes on the important role of executor in the entire gas metering system. Its performance not only directly affects the accuracy of metering control, but also directly relates to the safety of natural gas use. At present, the control valves equipped with smart gas flow meters usually use general-purpose DC geared motors to drive the opening and closing parts to make linear or rotary motions to complete the opening and closing of the valves. The reliability of the work is not high, the in...
