Embodiment Construction

[0013] A gas filter for a buoy-type pneumatic measuring instrument, comprising a gas filter housing 1, a water deflector 2, a deflector 3, a multi-function switch 4, an air pipe 5, an air source input joint 6, and a gas filter housing cover 7. Air source output joint 8, filter plate 9, screw 10, filter element 11, upper hollow bolt 12, slider 13, spring 14, lower hollow bolt 15, water bolt 16, bracket 17, explosion-proof plate 18, pressure gauge 19 , which is characterized in that a multi-function switch 4 is provided. When the multi-function switch 4 is located at a predetermined position, the gas passes through the switch and enters the gas filter. After the multi-function switch 4 rotates 180 degrees, the gas filter and the atmosphere are connected, and the gas filter The water in the filter flows into the water storage chamber; the gas is filtered twice through the filter element 11 and the filter plate 9 in the gas filter; the explosion-proof plate 18 can effectively preve...

Abstract

The invention discloses a gas filter applicable to a float type pneumatic measuring instrument. The gas filter comprises a gas filter shell, a water guide plate, a flow guide plate, a multifunctional switch, a gas pipe, a gas source input joint, a gas filter shell cover, a gas source output joint, a filtration plate, a bolt, a filter element, an upper hollow bolt, a sliding block, a spring, a lower hollow bolt, a water discharging bolt, a bracket, an anti-explosion plate and a pressure gage. The gas filter is characterized in that the multifunctional switch is arranged; when the multifunctional switch is in one position, gas enters the gas filter through the switch; after the multifunctional switch is rotated by 180 degrees, the gas filter is connected with the atmosphere, the water flows into a water storage chamber from the gas filter; the gas is filtered for three times in the gas filter through crude, middle and high filtration cups of the filter element and the filtration plate; the anti-explosion plate is capable of effectively avoiding the harm to the human body and equipment when accidents happen; and three filters which are connected in series can guarantee the quality of the filtered air.

Description

technical field [0001] The invention relates to the field of gas filtering devices, in particular to a gas filter for a buoy-type pneumatic measuring instrument. Background technique [0002] The buoy-type pneumatic measuring instrument has high requirements on the cleanliness of the gas, and the quality of the gas filtration directly affects the accuracy of the measurement, so high-precision gas filtration equipment is necessary. At this stage, the gas filters on the market have poor filtration effect, lack of multi-stage filtration, and the filtered gas and water oil are not separated, which is easy to cause pollution. Contents of the invention [0003] In order to solve the above problems, the present invention designs a filter plate and a filter element to filter twice in the gas filter, and connects three gas filters in series. The filter plate and the filter element in each gas filter are respectively coarse-effect filter unit, a medium-efficiency filter unit, and a...
