Description

увеличении ЛР регулирующий элемент стремитс прикрыть щель 8 и уменьшить расход воздуха и АР, Изменением усили пружины 9 с помощью винта 18 измен етс расход воздуха. Изменение давлени на выходе регул тора компенсируетс наличием корректирующего конуса 4. .as the LR increases, the regulating element tends to cover the slot 8 and reduce the air and AP flow rates. By changing the force of the spring 9 by means of the screw 18, the air flow rate changes. The change in pressure at the outlet of the regulator is compensated by the presence of correction cone 4..

При изменении давлени на входе регул тора , будет измен тьс давление в камере 20, что приведет к перемещению поршн 10. При увеличении давлени поршень 10 сожмет пружину 11, снижа тем самым заWhen the pressure at the inlet of the regulator changes, the pressure in the chamber 20 will change, which will lead to the movement of the piston 10. When the pressure increases, the piston 10 will compress the spring 11, thereby lowering

дание расхода и нейтрализу увеличение расхода от увеличени давлени на входе регул тора. При уменьшении давлени на входе, поршень под воздействием пружины 11 перемещаетс сжима пружину Э, тем самым увеличива задание расхода и нейтрализу снижение расхода от снижени давлени на входе.flow rate and neutralization increase in flow rate due to increase in pressure at the inlet of the regulator. When the inlet pressure decreases, the piston, under the influence of the spring 11, moves the compression spring E, thereby increasing the flow rate setting and neutralizing the decrease in the flow rate from the decrease in the inlet pressure.

Толкатель 12, выполненный в виде поршн , образует с камерой 20 демпфирующую пару, подавл автоколебани регулирующего элемента при работе регул тора,The pusher 12, made in the form of a piston, forms a damping pair with the chamber 20, suppressing self-oscillations of the regulating element during operation of the regulator,

Claims

; The claims

A gas flow regulator comprising a housing with inlet and outlet cavities between which a regulating body in the form of a first hollow piston is placed, the open end of which forms a throttling slit with the housing and is connected with a pusher made in the form of a second hollow piston with windows on the side surface moreover, the bottom of the first hollow piston is provided with an axial throttle hole in which a correction element is installed, made in the form of a cone rigidly connected to the housing, equipped with a fairing, the task spring and the setting spring nt, characterized in that, in order to increase the accuracy of regulation by compensating for the influence of pressure changes at the inlet of the regulator, an additional spring and an additional piston are installed in it, forming a cavity connected to the inlet cavity with the inlet and the second hollow piston through the second hollow piston a throttling hole, and in the cavity between the second hollow piston and the additional piston, a reference spring is installed, and an additional spring is installed between the additional piston and the set screw m.
