Problems solved by technology
The intelligent locator used in this kind of working condition often has frequent failures due to harsh environmental conditions
[0003] In the prior art, the intelligent positioner includes a housing, an electric / gas conversion unit and a gas circuit module arranged in the cavity of the housing, and the existing electric / gas conversion unit structure often causes gas to be discharged randomly in the housing of the intelligent positioner. Due to the water, oil and other impurities doped in the gas, there will be water, oil and other impurities inside the smart positioner, which will cause erosion of the internal parts of the positioner, thus affecting its normal operation
[0004] Therefore, how to solve the problem that impurities such as water and oil easily remain inside the smart locator in the prior art has become an important technical problem to be solved by those skilled in the art

The invention discloses an intelligent positioning device with a one-way vent valve. The intelligent positioning device with the one-way vent valve comprises a base, a piezoelectric valve, a piezoelectric valve deck arranged on one side of the piezoelectric valve, a piezoelectric valve body arranged on the other side of the piezoelectric valve, and a gas channel module connected with the other side of the piezoelectric valve body, and a rubber mat is arranged between the piezoelectric valve deck and the piezoelectric valve and is provided with a gas guide groove communicated with a vent hole of the piezoelectric valve. When the rubber mat is tightly attached to the piezoelectric valve, a closed gas guide channel is formed between the gas guide groove and the piezoelectric valve, the rubber mat is provided with a gas guide column communicated with the gas guide groove, a gas outlet is formed in the base, the gas guide column guides gas out of the intelligent positioning device through the gas outlet of the base, and the gas outlet of the base is provided with the one-way vent valve. Due to the fact that the intelligent positioning device with the one-way vent valve is arranged in this way, gas discharged out of the piezoelectric valve can be guided out of the intelligent positioning device, and impurities contained in the gas are prevented from having adverse effect on the intelligent positioning device.
Description
technical field [0001] The invention relates to the technical field of positioner devices, in particular to an intelligent positioner with a one-way exhaust valve. Background technique [0002] At the industrial site, with the huge demand for raw materials in the energy and chemical industry, the coal chemical industry has achieved rapid development. Coal chemical industry is characterized by severe accumulation of coal dust on site, unclean gas source, and a large amount of impurities such as water and oil in the gas source. The intelligent locator used in such working conditions often fails frequently due to harsh environmental conditions. [0003] In the prior art, the intelligent positioner includes a housing, an electric / gas conversion unit and a gas circuit module arranged in the cavity of the housing, and the existing electric / gas conversion unit structure often causes gas to be discharged randomly in the housing of the intelligent positioner. Due to the water, oil ...
