Изобретение относитс к теплоэнергетике , в частности к автоматиза-. ции контрол наличи пламени в топках . The invention relates to power engineering, in particular to automation. control the presence of flame in the furnaces.
Известно устройство дл контрол наличи пламени в топках, содержащее пневматический мост и включенные параллельно в его измерительную диагональ дифманометр и усилитель, соединенный с исполнительным механизмом, св занным с клапаном отсекателем подачи топлива 1 .A device for monitoring the presence of a flame in furnaces is known, comprising a pneumatic bridge and a differential manometer connected in parallel to its measuring diagonal and an amplifier connected to an actuator connected to the valve of fuel cutoff 1.
Однако известное устройство не позвол ет достичь требуемой надежности, так как переходный процесс в междроссельной камере измерительной ветви моста протекает дольше за счет того, что емкость из-за большей прот женности проведенной к контролируемому объекту пневматической линии чувствительного элемента всегда превьпвает емкость междроссельной камеры подпорной ветви моста.However, the known device does not allow to achieve the required reliability, since the transient process in the inter-throttle chamber of the measuring branch of the bridge takes longer due to the fact that the capacity due to the longer pneumatic line of the sensing element carried to the object being monitored exceeds the capacity of the inter-throttle camera .
Асинхронность переходных процес сов в междрвссельных камерах приводит к паразитному динамическому забросу перепада давлений в измерительной диагонали моста, что может привести к ложньш срабатывани м устройства. Этот заброс .достигает еще большей величины при включении и выключении прибора и может послужить причиной поломки дифманометра в измерительной The asynchrony of transients in inter-camera chambers leads to a parasitic dynamic injection of the pressure drop across the measuring diagonal of the bridge, which can lead to false positives of the device. This casting achieves even greater magnitude when the device is turned on and off and may cause a differential pressure gauge in the measuring device.
10 диагонали моста, а следовательно, и выхода из стро устройства в целом,10 diagonal of the bridge, and consequently, the failure of the device as a whole,
Цель изобретени - повьшение на дежности устройства.The purpose of the invention is to increase the reliability of the device.
Поставленна цель достигаетс тем, The goal is achieved by
15 что устройство снабжено переменным дросселем, включенным между усцлителем и пневматическим мостом.15 that the device is equipped with a variable choke connected between the actuator and the pneumatic bridge.
