Abstract

The utility model provides an intelligent device for emptying unqualified gas. The intelligent device comprises a qualified gas outlet, an unqualified gas outlet, a pipeline, a first pipeline, a second pipeline, a third pipeline, an inverted valve, a qualified purity pneumatic valve, an unqualified purity pneumatic valve, a flow control valve, a flowmeter, a pressure gauge interface, a purity sample port and a pressure-regulating valve. Through the intelligent device, intelligent management can be achieved by an intelligent controller in a unified manner to automatically detect purity of finished gas and control conversion of gas flow. The intelligent device can timely, accurately and clearly detect gas purity and control states of gas flow. Furthermore, the time difference during a gas flow conversion process is greatly shortened, purity of finished gas is ensured, and unqualified gas is prevented from entering use points to cause waste of finished gas or production accidents.

Description

Defective gas Intelligent evacuation device
Technical field
The utility model relates to gas purity purity equipment, especially detects and control purity, the flow of finished product gas, the gas evacuating device of pressure.
Background technique
In industrial production, the use purity of the gases such as oxygen and nitrogen is all had to higher requirement, it is the working effect that cannot reach expection that purity does not reach the gas that specify to require.Therefore in the production process of gas, must strictly control the purity of gas, need a kind of gas purity control gear.Control to finished product gas purity, with purity analysis instrument, detecting the purity of finished product gas follows the gas purity of intended target to compare, then, will meet the gas of target finished product gas purity requirement, by opening finished product gas pneumatic valve, open, defective gas pneumatic valve is in cutting out, finished product gas can flow out to user and use a little, if gas purity does not meet usage requirement, directly open defective gas pneumatic valve, defective gas is directly discharged; By the pressure regulator valve in device, carry out the adjusting of gas outlet pressure, by observing flowmeter, through flow control valve, carry out the adjusting of flow, make purity, flow, the pressure of final gas all reach usage requirement.
Model utility content
The purpose of this utility model is in order to guarantee can strictly control in gas generation the purity of gas.
In order to meet above-mentioned requirements, the utility model provides following technological scheme: a kind of defective gas Intelligent evacuation device, comprise qualified gas outlet, defective gas outlet and pipeline, also comprise the first pipeline, second pipe, the 3rd pipeline, safety check, qualified purity pneumatic valve, defective purity pneumatic valve, flow control valve, flowmeter, pressure gauge connection, purity sample tap and pressure regulator valve, described the first pipeline is branched off into second pipe and the 3rd pipeline along airflow direction, on described the first pipeline, along airflow direction, be provided with successively pressure regulator valve, purity sample tap, pressure gauge connection, flowmeter and flow control valve, on described second pipe, along airflow direction, be provided with successively defective purity pneumatic valve and defective gas outlet, on described the 3rd pipeline, along airflow direction, be provided with successively qualified purity pneumatic valve, safety check and qualified gas outlet.
The beneficial effects of the utility model: adopt this device just can realize purity that intelligent management detects finished product gas automatically by intelligent controller unification, control the conversion of gas flow; Can detect in time, accurately, clearly the state of a control of gas purity and gas flow; Significantly shorten the time difference existing in gas flow conversion process, and ensured the purity of finished product gas, avoided defective gas to enter into use point, caused scrapping or production accident of product.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of defective gas Intelligent evacuation device described in the utility model.
1, qualified gas outlet; 11, qualified purity pneumatic valve; 2, defective gas outlet; 22, defective purity pneumatic valve; 3, safety check; 4, flowmeter; 5, pressure gauge connection; 6, purity sample tap; 7, pressure regulator valve; 8, flow control valve; 91, the first pipeline; 92, second pipe; 93, the 3rd pipeline.
Embodiment
Below in conjunction with accompanying drawing, defective gas Intelligent evacuation device described in the utility model is further described.
As shown in Figure 1, the defective gas Intelligent evacuation device of the present embodiment, comprise qualified gas outlet 1, defective gas outlet 2 and pipeline, also comprise the first pipeline 91, second pipe 92, the 3rd pipeline 93, safety check 3, qualified purity pneumatic valve 11, defective purity pneumatic valve 22, flow control valve 8, flowmeter 4, pressure gauge connection 5, purity sample tap 6 and pressure regulator valve 7, the first pipeline 91 is branched off into second pipe 92 and the 3rd pipeline 93 along airflow direction, on the first pipeline 91, along airflow direction, be provided with successively pressure regulator valve 7, purity sample tap 6, pressure gauge connection 5, flowmeter 4 and flow control valve 8, on second pipe 92, along airflow direction, be provided with successively defective purity pneumatic valve 22 and defective gas outlet 2, on the 3rd pipeline 93, along airflow direction, be provided with successively qualified purity pneumatic valve 11, safety check 3 and qualified gas outlet 1.In the course of the work, gas to be detected enters the first pipeline 91, gathers gas sample detect purity through purity sample tap 6, if purity is defective, defective purity pneumatic valve 22 is opened, and gas is discharged by defective gas outlet 2; Pressure regulator valve 7 and flow control valve 8 start flow and the air pressure of adjustments of gas simultaneously, by observing the variation of pressure gauge connection 5 and flowmeter 4, finally make gas purity reach criterion of acceptability, qualified purity pneumatic valve 11 is opened, and qualified gas is emitted from qualified gas outlet 1.Safety check 3, for preventing gas backflow, affects gas purity.The defective gas Intelligent evacuation device of the present embodiment has adopted the Intelligent evacuation device that detects and control one at gas output end, replaced traditional large-scale self-contained unit that detects and regulate that is specifically designed to.On the one hand, save cost of production, on the other hand, can detect in time, accurately, clearly gas purity, and control and adjustments of gas purity.
The utility model is not limited to above embodiment and conversion.
