Dynamic pressure balance working principle of the pneumatic valve and how to use 2)

dynamic balance the pressure of the pneumatic valve, also self-reliance type differential pressure control, pneumatic valve, pressure controller, pressure balance valve of pneumatic and other famous, it is used to adjust the differential pressure of the pneumatic valve opening, the use of pressure drop in the pneumatic valve, make the management of change path resistance change, therefore, in the change of working conditions, to maintain the pressure basically remain unchanged, its principle is flow within a certain scope, can effectively control constant pressure control system, which increases the pressure, the system through pneumatic valve, close the small doohickey that can increase the pressure of the system, to ensure that the defendant, on the other hand, when the pressure drops, pneumatic valve automatically opens, differential pressure stays the same. Dynamic pressure balance principle of pneumatic valve: from the pneumatic valve, pneumatic valve cover, pneumatic valve spring, control of pipe pneumatic valve, pneumatic valve installed in the return pipe heating pipe, pneumatic valve working chamber by controlling the connecting pipe and the water supply. Eliminate the deviation caused by the external network traffic pressure fluctuations, increases when the water pressure P, small pressure difference between one and three laminated to drive down down pneumatic valve pneumatic valve core increase feeling, make the increase of P, in order to maintain a small two small constant. When the water supply pressure P decreased compound drive pneumatic valve core is moving, P or feeling, let little small 2 it is constant. No matter how in the change of pipeline pressure, dynamic pressure pneumatic valve can keep balance control object and the constant flow pressure. Use pneumatic valve: dynamic pressure balance, medium flow direction should be consistent with the direction arrow body; , pneumatic valve should be installed in the return pipe, impulse control, pneumatic valve, causing the pressure and the other end of the water supply pipe connections, suggested by the supplier in the guidelines for pressure pipeline installation/' pneumatic ball valve began to eliminate inhibition; Lead, prior to the pressure of water supply pipe should be installed filters, in order to avoid water quality and the loss caused by the automatic regulating pneumatic valve; Pneumatic valve should be installed before, water supply and return pipe pressure gauge is easy to adjust the control pressure; , such as heavy traffic, or found that the system is too small, because the blockage of debris may install components in front of the pneumatic valve can be/' closed - pneumatic ball valve Minutes, and then if it's lighter plug-ins, can be automatically eliminated, if not eliminate, pneumatic valve must open [ ] Check, eliminate the obstruction; Pressure adjustment, the control methods: adjust the pressure regulating lever anti-clockwise to observe.
