Abstract
The utility model relates to a gas stable output device in petroleum chemical industry, in particular to a device capable of making nitrogen stably output. The utility model adopts the technical scheme that the device capable of making nitrogen stably output comprises a nitrogen inlet, a pressure stabilizing tank, a sampling port, an emptying valve, a pressure regulating valve, a flow regulating valve, a flow gauge, an outlet magnetic valve and an outlet one-way valve which are connected in turn, and is characterized in that a sampling pressure stabilizing tank is arranged between the nitrogen inlet and the pressure stabilizing tank, the sampling port and the emptying valve are arranged between the sampling pressure stabilizing tank and the pressure stabilizing tank in turn, and a communicating one-way valve is further arranged between the emptying valve and the pressure stabilizing tank. The device capable of making nitrogen stably output has short sampling acceptable time, stable pressure in the pressure stabilizing tank, simple structure and convenient installing, not only saves energy, but also saves time.
Description
Technical field
A kind of gas that the utility model relates in the petroleum chemical industry is stablized output unit, especially relates to a kind of device that can make the stable output of nitrogen.
Background technique
At present, nitrogen is indispensable a kind of protection gas in petroleum chemical industry, therefore; nitrogen generator just becomes indispensable equipment in the petroleum chemical industry, is discontinuous production technology but the present equipment of making nitrogen adopts, and the back connects a surge tank and comes steady pressure and sampling monitoring; yet; surge tank is big more, and jar internal pressure is stable more, but the qualified time of taking a sample is long more; be unfavorable for energy saving; surge tank is more little, and the qualified time of taking a sample is short more, but jar internal pressure is just unstable.
The model utility content
The utility model purpose is exactly the defective at existence of the prior art, and a kind of a kind of device that can make the stable output of nitrogen of take a sample qualified time weak point and pressure stability is provided.
Its technological scheme is: connected to form successively by nitrogen inlet, surge tank, sample tap, atmospheric valve, pressure regulator valve, flow control valve, flowmeter, outlet solenoid valve and outlet one-way valve, it is characterized in that: the sampling surge tank is set between nitrogen inlet and surge tank, sample tap and atmospheric valve are successively set between sampling surge tank and the surge tank, also are provided with between atmospheric valve and the surge tank and are communicated with one-way valve.
Described sampling surge tank is littler than the volume of surge tank.
Above-mentioned technology also can be improved to: connected to form successively by nitrogen inlet, surge tank, sample tap, atmospheric valve, pressure regulator valve, flow control valve, flowmeter, outlet solenoid valve and outlet one-way valve, it is characterized in that: the sampling surge tank is set between nitrogen inlet and surge tank, sample tap, atmospheric valve and electromagnetism outlet valve are successively set between sampling surge tank and the surge tank.
Effect of the present utility model is that the sampling qualified time is short, and the surge tank internal pressure is stable, and simple in structure, easy for installation, not only energy saving has also been saved the time.
Description of drawings
Embodiment:
Embodiment 1: with reference to accompanying drawing 1, sampling surge tank 1 is set between nitrogen inlet 0 and surge tank 5, sample tap 2 and atmospheric valve 3 are successively set between sampling surge tank 1 and the surge tank 5, also be provided with between atmospheric valve 3 and the surge tank 5 and be communicated with one-way valve 4, surge tank 5 is connected successively with pressure regulator valve 6, flow control valve 8, flowmeter 7, outlet solenoid valve 9 and outlet one-way valve 10 again, and sampling surge tank 1 is littler than the volume of surge tank 5.
During use, the surge tank 1 of will taking a sample is connected with nitrogen inlet 0, open sample tap 2 samplings, as the nitrogen gas purity deficiency, open atmospheric valve 3, defective nitrogen is discharged, treat that nitrogen gas purity that the control of nitrogen gas purity ANALYZER shows reaches setting value after, close atmospheric valve 3, open and be communicated with one-way valve 4, passing nitrogen enters in the surge tank 5, regulates pressure regulator valve 6, make its be operated in regulate under the pressure, regulate flow control valve 8 again, the flow that can obtain wanting is opened outlet solenoid valve 9, just can obtain qualified stable nitrogen output rapidly from one-way valve 10 then.
Embodiment 2: with reference to accompanying drawing 2, sampling surge tank 1 is set between nitrogen inlet 0 and surge tank 5, sample tap 2, atmospheric valve 3 and outlet solenoid valve 9 are successively set between sampling surge tank 1 and the surge tank 5, and surge tank 5 is connected with pressure regulator valve 6, flow control valve 8, flowmeter 7 and outlet one-way valve 10 more successively.
During use, the surge tank 1 of will taking a sample is connected with nitrogen inlet 0, opens sample tap 2 samplings, as the nitrogen gas purity deficiency, open atmospheric valve 3, defective nitrogen is discharged, after treating that nitrogen gas purity that nitrogen gas purity ANALYZER control shows reaches setting value, close atmospheric valve 3, open outlet solenoid valve 9, passing nitrogen enters in the surge tank 5, through regulating pressure regulator valve 6, make its be operated in regulate under the pressure, again through regulating flow control valve 8, directly obtain qualified stable nitrogen output rapidly from one-way valve 10.
Claims (3)
1, a kind of device that can make the stable output of nitrogen, connect to form successively by nitrogen inlet, surge tank, sample tap, atmospheric valve, pressure regulator valve, flow control valve, flowmeter, outlet solenoid valve and outlet one-way valve, it is characterized in that: the sampling surge tank is set between nitrogen inlet and surge tank, sample tap and atmospheric valve are successively set between sampling surge tank and the surge tank, also are provided with between atmospheric valve and the surge tank and are communicated with one-way valve.
2, the device that can make the stable output of nitrogen according to claim 1, it is characterized in that: described sampling surge tank is littler than the volume of surge tank.
