Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the present invention provides an air inlet end switch for a QSF-III type plug-in air intake device, comprising: a sealing block 1 and a steel pipe 2; the sealing block 1 is cylindrical, a three-way pipeline is arranged on the top surface and the side wall of the sealing block 1, a first channel is arranged on the side wall of the sealing block 1 along the radial direction, a second channel is arranged from the center of one top surface of the sealing block 1 along the axial direction, and the first channel and the second channel are formed by intersection; the diameter of the section of the sealing block 1 is larger than the inner diameter of the steel pipe 2, the sealing block is embedded in the steel pipe 2 in an interference fit mode, symmetrical second through holes are axially formed in the outer portion of the steel pipe 2, and the aperture of each second through hole is smaller than or equal to that of a first through hole formed in the side face of the sealing block 1 by a first channel; the air inlet pipe of the QSF-III type plug-in air taking device is inserted into the first channel, and the steel pipe 2 is connected to a storage pipeline of the gas to be detected.
And the two ends of the steel pipe 2 are fixedly provided with baffle plates 3 for sealing the steel pipe 2.
Wherein, baffle 3 that is close to QSF-III type bayonet gas taking device one side sets for first baffle 31, and the middle part sets up the through-hole to make the admission pipe get into the first passageway of sealed piece 1 through first baffle, and first baffle 31 through-hole edge sets up the screw thread, and pass through screw thread fit's mode with the screw thread that sets up in the intake pipe pipeline outer wall, with intake pipe and steel pipe 2 fixed connection.
The utility model discloses a QSF-III type bayonet gas taking device inlet end switch utilizes old and useless material processing to form, and the effect and safety ring guard are carried in the loss reduction, can effectively solve problem and the hidden danger that exists when the gas sensor gauge outfit is daily changed, is calibrated and is maintained for the pipeline.
The method comprises the following steps:
firstly, a proper sealing block 1 is tightly sleeved in a first channel of an air inlet and outlet hole of a QSF-III type plug-in air intake and outlet device, and two holes with the same size are punched on the equal-diameter sealing block 1 in comparison with the air inlet and outlet hole of the air intake device.
Fixing the sealing block 1 on the inner wall of the steel pipe 2, drilling two holes with equal diameter at the position of the steel pipe 2 for fixing the sealing block 1, and sealing the tail end by a baffle 3.
