Description
Technical Field
The utility model relates to a standard gas uses equipment technical field, in particular to standard gas cylinder shallow.
Background
At present, a bottle of standard gas is connected on the instrument by the standard gas. Because the daily use needs to repeatedly use the standard gas of the same variety with different concentrations, the repeated taking is inconvenient, the use efficiency is influenced, and the labor intensity of testers is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that the above-mentioned weak point that exists in the gaseous use of current standard provides a standard gas cylinder shallow, places the standard gas cylinder of same variety, different concentration on this standard gas cylinder shallow to convenient and practical.
The utility model discloses the technical problem that will solve can realize through following technical scheme:
a standard gas cylinder cart comprises a cart body, wherein a cylinder frame is arranged on the cart body, and a plurality of gas cylinder spaces for placing gas cylinders are arranged on the cylinder frame according to the number of standard gas cylinders of the same variety and different concentrations; a pipeline is laid on the bottle rack, the pipeline is provided with inlet connectors with the same number as the gas bottle spaces, each inlet connector is correspondingly arranged in each gas bottle space, an inlet valve is arranged on each inlet connector, the pipeline is provided with an outlet connector, and a pressure reducer is arranged on each outlet connector; the pipeline is also connected with a vacuum meter and a vacuum pump through a vacuum valve.
When the device is used, all inlet valves and vacuum valves are confirmed to be in a closed state, then standard gas cylinders of the same variety and different concentrations are placed in corresponding gas cylinder spaces and then connected with inlet connectors arranged in the gas cylinder spaces, after the cart is pushed to the position near an instrument, the vacuum valves and the vacuum pump connectors are connected, and then the outlet connectors are connected to the instrument. When the standard gas with a certain concentration is needed, the gas cylinder valve, the inlet valve and the pressure reducer of the standard gas with corresponding concentration are opened in sequence to be used normally. When the standard gas of another concentration is needed to be used, the gas cylinder valve and the inlet valve of the previous bottle of standard gas are closed firstly, the pressure reducer is closed after the reading of the pressure reducer meter is reset to zero, the vacuum valve is opened, the vacuum pump is opened, the pipeline is vacuumized, the vacuum valve is closed after the vacuum pumping, the gas cylinder valve, the inlet valve and the pressure reducer which need to use the standard gas of the concentration are opened in sequence, and the standard gas of different concentrations can be used normally, so that the standard gas is not interfered. After all experiments were completed, all cylinder valves and pressure reducers were closed. And opening all inlet valves and vacuum valves, and closing all inlet valves, vacuum valves and vacuum pumps after the pipeline is vacuumized.
The utility model discloses place the standard gas cylinder of same variety, different concentration on a shallow, make things convenient for the propelling movement, avoid taking repeatedly, improved the availability factor and reduced tester's intensity of labour.
Drawings
Fig. 1 is a schematic view of the overlooking principle of the standard gas cylinder cart of the utility model.
Detailed Description
The invention is further described below with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, there is shown a standard gas cylinder cart comprising a cart 10, a handle 1 may be provided on one side of the cart 10, and releasable wheels may be provided on the bottom of the cart 10 to facilitate pushing and positioning of the cart.
The cart 10 is provided with a bottle rack 20, and the bottle rack 20 is made of metal section bars or plastic section bars. The bottom of the bottle holder 20 is secured to the cart 10 using fasteners.
A plurality of gas bottle spaces 21 for placing gas bottles are configured on the bottle rack 20 according to the number of standard gas bottles of the same variety and different concentrations; one standard gas cylinder 30 is placed in each cylinder space 21.
A pipeline 40 is laid on the cylinder holder 20, the pipeline 40 has the same number of inlet joints 41 as the number of the gas cylinder spaces 21, each inlet joint 41 is correspondingly arranged in each gas cylinder space 21, and an inlet valve 42 is arranged on each inlet joint 41.
The pipe 40 has an outlet connection 43, on which outlet connection 43 a pressure reducer 44 is arranged; a vacuum pump 46 is also connected to the line 40 via a vacuum valve 45. A vacuum gauge 47 is provided between the vacuum valve 45 and the vacuum pump 46.
When the device is used, all the inlet valves 42 and the vacuum valves 45 are confirmed to be in a closed state, then the standard gas cylinders 30 of the same type and different concentrations are placed in the corresponding cylinder spaces 21 and then connected with the inlet connectors 41 arranged in the cylinder spaces 21, after the cart is pushed to the vicinity of the device, the vacuum valves 45 are connected with the vacuum pump connectors 48, and then the outlet connectors 43 are connected to the device. The vacuum pump connection 48 is a connection point between the vacuum pump 46 and the vacuum valve 45, and the vacuum pump 46 can be detached from the whole apparatus by detaching or attaching the vacuum pump.
When the standard gas with a certain concentration is needed, the gas cylinder valve, the inlet valve 42 and the pressure reducer 44 of the standard gas with the corresponding concentration are opened in sequence to be used normally. When the standard gas with another concentration is needed to be used, the gas cylinder valve and the inlet valve 42 of the previous bottle of standard gas are closed firstly, the pressure reducer 44 is closed after the reading of the pressure reducer meter is zero, the vacuum pump 46 is started, the pipeline 40 is vacuumized, the vacuum valve 45 is closed after the vacuum pumping, and then the gas cylinder valve, the inlet valve 42 and the pressure reducer 44 which need to use the standard gas with the concentration are opened in sequence to be normally used, so that the standard gas with different concentrations is ensured not to be interfered. After all experiments are completed, all cylinder valves and pressure reducers 44 are closed. All inlet valves 42 and vacuum valves 45 are opened, all inlet valves 42 and vacuum valves 45 are closed after the pipe is evacuated, and the vacuum pump 46 is closed.
