Abstract

The invention discloses a multifunctional pressure detecting and measuring switch, wherein a magnetic switch sliding frame is arranged on the surface of a cylinder body and axially arranged along the cylinder body, a magnetic switch is installed on the magnetic switch sliding frame, and a magnetic switch fixing bolt for fixing the position of the magnetic switch is arranged on the magnetic switchsliding frame; a positive-pressure detection input port is arranged in the rear end cover of the cylinder body, a vacuum-pressure detection port is arranged at a front end cover, a spring is arrangedin the cylinder body, and one end of the spring is connected with a piston; a magnetic ring is arranged on the piston; a pressure-indicating dial gauge is arranged at one side of the magnetic switch sliding frame and adapted to the moving position of the magnetic switch; a limiting bolt with scales is arranged at the end part of the cylinder body and connected with the other end of the spring; and a sealing device is arranged between the limiting bolt and the cylinder body. The invention has the functions of vacuum pressure measurement, positive pressure measurement, pressure difference measurement, vacuum pressure switching, positive pressure switching, pressure difference switching and the like and can satisfy various requirements.

Description

technical field [0001] The invention relates to a measuring switch, in particular to a multifunctional pressure detection and measuring switch. Background technique [0002] The usual pressure switch is an automatic controller that receives a pressure signal and acts. It has a pressure setting function. When the system pressure of the equipment reaches or exceeds the upper limit set by the pressure controller, the controller will automatically cut off the circuit, so that the equipment will stop and play an automatic protection role. When the system pressure is lower than the lower limit of the set pressure, the controller will automatically switch on the circuit to make the equipment return to normal operation. But the usual pressure switch does not have the function of adapting to various fluids, positive and negative pressure detection and measurement functions, pressure difference detection and measurement functions, etc. Contents of the invention [0003] In order t...
