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 a back pressure valve device at the outlet of an extraction kettle that is convenient for pressure adjustment, including an outlet pipe and a back pressure valve body, and also includes a resonance sensing component and a pressure adjustment component. A back pressure valve body is fixedly connected to the side, and a resonance sensing component is fixedly connected to the outlet pipe to detect whether resonance occurs between the system and the back pressure valve body, and a pressure adjustment component is fixedly connected to the back pressure valve body. The outlet of the extraction kettle, which is convenient for pressure adjustment, is equipped with a back pressure valve device. When the induction diaphragm and the outlet pipeline resonate, the vibration amplitude of the induction diaphragm at this time is the largest. At this time, the closer the induction diaphragm is to the magnetic filling block, the closer the closed conductor is. The magnetic field is the strongest. At this time, the electric field voltage generated by the closed conductor reaches the working voltage of the piezoresistor, which makes the electrostrictive axis shorten, so that the pressure diaphragm is tightened. At this time, the natural frequency of the pressure diaphragm increases, so it can be Reduce the effect of resonance.

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...
