Problems solved by technology

[0002] When the calibration platform in the prior art is in use, because it is single, it can only calibrate one instrument to be tested, which will bring a lot of trouble to the workers, and the efficiency is low, which not only affects the mood of the user, but also affects the work. Efficiency also has a big impact
The general calibration station can calibrate a few more devices, but the equipment is heavy and cannot go upstairs, and it is not easy to move.

Embodiment Construction

[0013] Such as Figure 1-Figure 5 As shown, a comprehensive calibration bench for a gas alarm has a housing 6 and a test system installed on the housing 6. The test system includes a plurality of control valves 2, a plurality of flow meters 3, Multiple inlet pipes 4, multiple outlet pipes 5, flow divider 7 and one-way valve 9; each inlet pipe 4 is correspondingly connected to a control valve 2, and multiple control valves 2 are connected to the flow divider 7 through the one-way valve 9 to divide the flow The device 7 is connected to the flow meter 3, and each flow meter 3 is connected to an external instrument to be inspected through an air outlet pipe 5.

[0014] In this embodiment, there are 4 control valves, 4 air inlet pipes, 12 air outlet pipes 5 and flow meters 3, and the diverter 7 has 13 holes. The inlet pipe 4 and the outlet pipe 5 are both silicone tubes. 12 products can be inspected at a time, four different concentrations of gas can be passed at one time, and the i...

Abstract

The invention discloses a comprehensive verification table of a gas alarm instrument and relates to the technical field of gas alarm instrument verification. The verification table comprises a shell and a testing system installed on the shell, wherein the testing system comprises a plurality of control valves, a plurality of flowmeters, a plurality of gas feeding pipes, a plurality of gas discharge pipes, a shunt and a one-way valve which are installed on the shell; each gas feeding pipe is correspondingly connected with one control valve; the plurality of control valves are connected with the shunt through the one-way valve; the shunt is connected with the flowmeters; and each flowmeter is connected with external equipment to be detected through one gas discharge pipe.

Description

Technical field [0001] The invention relates to a gas alarm device, and in particular provides a gas alarm device comprehensive calibration platform. Background technique [0002] When the calibration table under the prior art is used, due to its singularity, it can only calibrate one instrument to be checked, which will cause great troubles to workers and low efficiency, which not only affects the mood of users, but also affects the work. Efficiency also has a big impact. Generally, the calibration station can check several more equipments, but the equipment is bulky, cannot go upstairs, and is not easy to move. Summary of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a comprehensive calibration platform for a gas alarm, which has a wide range of applications, can pass multiple gases of different concentrations at a time, and has a fast inspection speed. [0004] The present invention is realized by t...
