Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, the present invention provides an effective gas sampling device, including: waterproof dustcoat 1, filter mantle 2 and probe rod 3, waterproof dustcoat 1 is cylindricly, and its inside cavity. The probe rod 3 is connected with the waterproof outer cover 1, one end of the probe rod 3 is inserted into the waterproof outer cover 1, and the other end of the probe rod is exposed out of the waterproof outer cover 1. The filter mantle 2 with 3 one end of probe rod are connected just the filter mantle 2 is located inside waterproof dustcoat 1, the filter mantle 2 is cylindricly.
Referring to fig. 2 to 4, the waterproof housing 1 includes a cylindrical housing 11 and a nut 12 disposed at one end of the cylindrical housing 11, the nut 12 has an internal thread, the connection portion between the probe 3 and the waterproof housing 1 has an external thread, and the external thread of the probe 3 is screwed with the internal thread of the nut 12 to fixedly connect the probe 3 and the waterproof housing 1. The outer cylindrical surface of the probe rod 3 is provided with a flange 31, and the end surface of the flange 31 is abutted against the nut 12. The cylindrical cover 11 and the nut 12 are fixed together by welding, and the outer surfaces of the cylindrical cover 11 and the nut 12 are fully welded.
Referring to fig. 5, the filter housing 2 includes a filter housing base 21 and a housing 22 connected to the filter housing base 21, the filter housing base 21 is made of 304 stainless steel, the housing 22 is made of titanium alloy powder through die casting, and the housing 22 can filter particles with a size of 1.5 μm or more. The inside internal thread that is equipped with of filter mantle base 21, probe rod 3 with the junction of filter mantle 2 is equipped with the external screw thread, and the internal thread of filter mantle base 21 and the external screw thread spiro union of probe rod 3 are in order to be connected filter mantle 2 and probe rod 3 fixed connection.
