Abstract
The utility model relates to a gaseous switched systems in full -automatic laboratory, gas piping including a plurality of gas cylinder gas outlets, its characterized in that: still including controller and pressure sensor, check valve, automatic switch -over valve, adjustment valve, all setting up the check valve on the gas piping of each gas cylinder gas outlet, gas piping is connected to the automatic switch -over valve jointly behind the check valve, is connected to the system gas outlet after the adjustment valve is connected on the road to the outlet duct of automatic switch -over valve, the last pressure sensor that installs of gas piping, and each pressure sensor's signal output part is connected to the controller, and the automatic switch -over valve is connected to the controller. The utility model discloses structural design scientific and reasonable realizes that the zero clearance of many bottles of gases is taken a breath, and assurance test's continuity and reliability improve test efficiency and accuracy, practice thrift test time and gaseous cost.
Description
Technical field
This utility model relates to experimental apparatus for testing, particularly a kind of full-automatic laboratory air switched system.
Background technology
In Package Testing is tested, lot of experiments process all needs use test gas. Such as, the pressure system gas of cylinder in the detection of packaging pull resistance; Test purging gas etc. Laboratory is when detecting, it is necessary to use the gases such as nitrogen, oxygen, argon and helium. Need many bottles of gases just can complete for the gas that gas consumption is bigger. At present, in experimentation, after gas is finished one bottle, artificial single carry out the replacing of gas cylinder. This situation is it cannot be guaranteed that the continuous supply of gas, and gas stops even terminating with being easily caused test to half, causes wasting of whole pre-stage test. And, frequently from equipment dismounting easily gas leakage, if lacking defecator, the gaseous impurity of supply is too many, and the equipment that also can affect uses and testing result.
Summary of the invention
The purpose of this utility model is in that to overcome the deficiencies in the prior art, it is provided that a kind of gapless ventilation realizing many bottles of gases, it is ensured that the seriality of test and reliability, improves the full-automatic laboratory air switched system of test efficiency and accuracy.
This utility model solves its technical problem and is achieved through the following technical solutions:
A kind of full-automatic laboratory air switched system, gas piping including multiple gas cylinder gas outlets, it is characterized in that: also include controller and pressure transducer, check valve, automatic transfer valve, adjustment valve, the gas piping of each gas cylinder gas outlet is respectively provided with check valve, gas piping is commonly connected to automatic transfer valve after check valve, it is connected to system gas outlet after the outlet pipe of automatic transfer valve connects adjustment valve, gas piping is installed pressure transducer, the signal output part of each pressure transducer is connected to controller, controller connects automatic transfer valve.
And, described multiple gas cylinders are 2-5 platform gas cylinder.
Advantage of the present utility model and having the beneficial effect that
1, this full-automatic laboratory air switched system, the switching of both sides gas circuit adopts full-automatic mode to carry out, and when side airline pressure is lower than a certain setting value, system can be automatically switched off this road gas circuit, and automatically opens up another road gas circuit.When another road airline pressure is lower than a certain setting value, system can close again this gas circuit, automatically switches to again a road of gas, thus realizing full-automatic switching. Coroner has only to ensure systems stay stable operation at the gas cylinder of the side that replacing gas is used up in time.
2. this utility model scientific structure design is reasonable, it is achieved the gapless ventilation of many bottles of gases, it is ensured that the seriality of test and reliability, improves test efficiency and accuracy, saves test period and gas cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Accompanying drawing illustrates:
1-gas cylinder, 2-pressure transducer, 3-gas piping, 4-check valve, 5-automatic transfer valve, 6-system gas outlet, 7-adjustment valve.
Detailed description of the invention
Below by specific embodiment, the utility model is described in further detail, and following example are illustrative, is not determinate, it is impossible to limits protection domain of the present utility model with this.
A kind of full-automatic laboratory air switched system, gas piping 3 including multiple gas cylinder 1 gas outlets, it also includes controller and pressure transducer 2, check valve 4, automatic transfer valve 5, adjustment valve 7, the gas piping of each gas cylinder gas outlet is respectively provided with check valve, gas piping is commonly connected to automatic transfer valve after check valve, it is connected to system gas outlet 6 after the outlet pipe of automatic transfer valve connects adjustment valve, gas piping is installed pressure transducer, the signal output part of each pressure transducer is connected to controller, and controller connects automatic transfer valve.
Gas cylinder is 2-5 platform gas cylinder.
The operation principle of this full-automatic laboratory air switched system is:
The switching of both sides gas circuit adopts full-automatic mode to carry out, and when side airline pressure is lower than a certain setting value, system can be automatically switched off this road gas circuit, and automatically opens up another road gas circuit. When another road airline pressure is lower than a certain setting value, system can close again this gas circuit, automatically switches to again a road of gas, thus realizing full-automatic switching. Coroner has only to ensure systems stay stable operation at the gas cylinder of the side that replacing gas is used up in time.
Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope without departing from this utility model and claims, various replacements, to change and modifications be all possible, therefore, scope of the present utility model is not limited to embodiment and accompanying drawing disclosure of that.
