Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device with a back pressure valve at the outlet of the extraction kettle that is easy to adjust the pressure. The valve may resonate with the system, which will have a serious impact on the work of the back pressure valve, and may damage the back pressure valve and cause dangerous problems

Abstract

The invention relates to the technical field of extraction equipment, and discloses an extraction kettle outlet counterbalance valve device facilitating pressure adjustment. An outlet pipeline and a counterbalance valve body are included, and a resonance induction assembly and a pressure adjusting assembly are further included. The counterbalance valve body is fixedly connected to the left side of the outlet pipeline, the resonance induction assembly is fixedly connected into the outlet pipeline and used for detecting whether resonance occurs between the system and the counterbalance valve body or not, and the pressure adjusting assembly is fixedly connected into the counterbalance valve body. According to the extraction kettle outlet counterbalance valve device facilitating pressure adjustment, when an induction diaphragm and the outlet pipeline generate resonance, the vibration amplitude of the induction diaphragm is the largest at the moment, the induction diaphragm is closer to a magnetic filling block, the magnetic field where a closed conductor is located is the strongest at the moment, and the voltage of the electric field generated by the closed conductor reaches the working voltage of a piezoresistor at the moment; and an electrostriction shaft is shortened, so that a pressure diaphragm is tensioned, the inherent frequency of the pressure diaphragm is increased, and therefore the resonance influence can be reduced.

Description

technical field [0001] The invention relates to the technical field of extraction equipment, in particular to an extraction kettle outlet equipped with a back pressure valve device for easy pressure adjustment. Background technique [0002] When the pressure of the pipeline or equipment container is unstable, the back pressure valve can maintain the required pressure of the pipeline, so that the pump can output the flow normally. Generate upward pressure, when the pressure is high enough, the spring is compressed, the fluid pushes up the diaphragm to form a channel, and flows out from the outlet of the back pressure valve; if the fluid pressure is not enough, it will form a suffocating pressure, so that the inlet pressure rises until it reaches the rated pressure, The diaphragm is lifted up to form a passage, and the rated pressure of the back pressure valve can be adjusted, usually by adjusting the ejector rod at the upper end of the spring to adjust the length of the sprin...
