Abstract

The invention relates to a device for measuring transition function of a slide valve type pneumatic reversing valve, and belongs to the fields of industrial automation and system technology. The connection relationship is that: a stepping motor is fixed on the left side of a tool platform and is fixedly connected with the left end of a leading screw; a leading screw nut is arranged at the right end of the leading screw and is in contact connection with a linear guide rail 4 fixed on the tool platform through one end of a read head; the other end of the read head is in contact connection with a displacement sensor; the leading screw nut is connected with a tested valve body through a tested valve core; gas ports corresponding to the port 1 and the port 2 of the tested valve body are formed on the tool platform contacted with the bottom surface of the tested valve body; pressure sensors of the port 1 and the port 3 are arranged below the tool platform; a stop valve is arranged at the lower end of each pressure sensor; the top surface of the tested valve body is in contact connection with a plugging mechanism; the plugging mechanism is fixedly connected with a plugging cylinder through a piston rod of the plugging cylinder; and a gas source is arranged in the tool platform. The device can acquire the transition function of the tested valve precisely and efficiently and has a wide application range.

Description

technical field [0001] The invention relates to a measuring device for the transition function of a sliding valve type pneumatic reversing valve, belonging to the technical field of industrial automation and systems. Background technique [0002] The spool type pneumatic reversing valve is widely used in the field of industrial automation. In some applications, such as limit control, in order to make the limit control smoother, it is necessary to accurately measure the transition function of the reversing valve. At present, the detection of the transition function of the spool type pneumatic reversing valve is mostly done manually. This method not only cannot guarantee the test accuracy, but also has extremely low work efficiency. For occasions with high requirements on the transition function of the reversing valve, the application of the spool type reversing valve has been greatly restricted. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to p...
