DETAILED DESCRIPTION
[0023] The present invention provides a gas analysis sampling valve group, such as Figure 1-4 As shown, it includes a mounting base 101, and horizontal mounting plates 103 are fixed on both sides of the mounting base 101. The horizontal mounting plates 103 are provided with mounting holes 102, and are convenient for positioning and mounting with the air separation module through the mounting holes 102. The top of the mounting base 101 is provided with a plurality of mounting slots running through the top and bottom, and the control valve 115 can be installed in the mounting slot. A detachable snap plate 107 is installed on the upper end of the mounting base 101 and below the control valve 115 on each side. The snap plate 107 is connected to the top of the mounting base 101 by threaded mounting. A shock-proof gasket 108 is inserted under the snap plate 107 during installation. The shock-proof gasket 108 is annular and contacts and abuts against the outer end surface of the control valve 115.
[0024] It should be further explained that the shock-proof gasket 108 is an elastic gasket, which can reduce the vibration force and provide shock-proof protection for the control valve 115 .
[0025] Furthermore, a regulating valve 104 is rotatably provided at the top of the control valve 115 for regulating the flow of the control pipeline.
[0026] Furthermore, an input pipe 106 is provided on one side of an outer end surface of the control valve 115 , and a connecting pipe 116 is provided between two adjacent control valves 115 .
[0027] It is worth noting that the two control valves 115 form a group, and the connecting pipe 116 connects the two adjacent control valves 115 .
[0028] Furthermore, a mounting plate 110 is fixedly provided on one side of the top of the installation base plate 101 , and one end of the input pipe 106 passes through the mounting plate 110 and plays a stable supporting role.
[0029] Furthermore, a plurality of support detection boxes 105 are fixedly installed between the mounting plate 110 and the control valve 115 and at the top of the installation base plate 101 , and the support detection boxes 105 are arranged in a matrix.
[0030] Furthermore, a detection connecting pipe 117 is provided on the other side of the control valve 115 and is directly connected to the support detection box 105. A sampling pipe 111 is provided between the support detection box 105 and the mounting plate 110, and the sampling pipe 111 passes through the mounting plate 110 to provide support and stability.
[0031] It should be further explained that a flow rate detector is provided in the support detection box 105 to detect the flow rate of the air flow after the detection connecting pipes 117 on both sides are connected, and a vibration detector is provided in the mounting plate 110 .
[0032] Furthermore, a plurality of monitoring cavities 114 with outward openings are provided on one side of the front end of the installation base plate 101 . The monitoring cavities 114 are arranged in a matrix, and flow detection meters 113 are installed in the monitoring cavities 114 .
[0033] It should be further explained that the flow detection meter 113 is connected to the flow velocity detector signal in the support detection box 105, and realizes real-time monitoring and data display of the flow velocity.
[0034] When using this solution, the mounting base plate 101 is first driven to move as a whole to the mounting position in the air cooling module, and the horizontal mounting plates 103 on both sides are used to achieve a stable mounting connection.
[0035] Then, each control valve 115 is installed and inserted into the installation slot at the top of the installation base plate 101. At the same time, the shock-proof gasket 108 is installed and inserted. After the shock-proof gasket 108 contacts and abuts against the surface of the installation base plate 101, the snap plate 107 is installed and buckled onto the top of the shock-proof gasket 108, thereby achieving stable installation of the control valve 115 and further shock-proof effect.
[0036] Then, the various input pipes 106 are connected, and then the regulating valves 104 at both ends are adjusted to adjust the flow rate of the air separation raw materials flowing through the input pipes 106 and the connecting pipes 116. The flow rate detector in the support detection box 105 is used to detect the flow rate of the air separation raw materials passing through, and the signal is transmitted to the flow detection meter 113, which makes it convenient for the staff to read the flow rate, and further facilitates adjustment through the regulating valve 104 to achieve the best working requirement state.
[0037] When the air separation module is working and generates vibration, the inserted shock-absorbing gasket 108 can further achieve a shock-absorbing effect and improve the connection stability of the input pipe 106.
[0038] At the same time, the connection between the sampling pipe 111 and the mounting plate 110 provides a stable support effect for the support detection box 105. Since the support detection box 105 is stably set, the flow rate detection stability of the detection connecting pipes 117 on both sides is further improved, and the impact of the air separation valve due to vibration is minimized. At the same time, the overall vibration of the installation base plate 101 is detected by the vibration detector in the mounting plate 110, and a signal is output. The signal transmission is centralized through the Internet of Things technology. When the vibration force is too large, the staff can be warned in advance and prevent malfunctions.
[0039] When the sampling pipe 111 is connected to the instrument panel detector, part of the oxygen passing through the interior of the support detection box 105 can be extracted through the sampling pipe 111, thereby achieving the effect of sampling detection.
[0040] When the regulating valve 104 on one side is closed, the standard sample gas can be connected to the input pipe 106 on the other side. At this time, the standard sample gas flows through the analyzer to calibrate the instrument, thereby improving the detection accuracy.
[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
