Abstract
The utility model discloses a gas-liquid separating device for low temperature liquid, which comprises an inner container [1], an outer shell [5] and a shell, wherein the shell is located between the inner container and the outer shell and comprises a vacuum multilayer twisting heat insulating jacket [3], a liquid inlet [2], a liquid outlet [6] and a gas return port [4] are arranged on the shell, and one-way check valves are respectively arranged on the liquid inlet, the liquid outlet and the gas return port. The gas-liquid separating device has simple structure, convenient installation, and safe and reliable use, can be used to separate liquid and gas of low temperature liquid which flows through pipelines effectively, and can prevent a pump and a flowmeter from being damaged and influenced by gas etching.
Description
Technical field
The utility model relates to a kind of separator, is specifically related to a kind of gas-liquid separation device that is used for cryogenic fluid pump conveying or metering system.
Background technology
The cryogen pipeline of flowing through, because pressure changes or absorbs heat and can cause and produce bubble in the fluid, when passing through pump or flow measurement timing, because the existence of bubble, can form cavitation, the severe impairment that the inside components and parts of pump and quantifier are caused, and can have a strong impact on measuring accuracy, can't accurately obtain measuring numerical value.Count example with the mass flow of flowing through, when containing bubble 10%, error in dipping generally is increased to 15%～20%.
The utility model content
The purpose of this utility model provides a kind of cryogen gas-liquid separation device that is used for, and it can allow cryogen separate infringement and the influence of avoiding pump and flowmeter to avoid cavitating at the laggard promoting the circulation of qi liquid of the pipeline of flowing through.
The technical scheme that the utility model adopted is:
A kind of cryogen gas-liquid separation device that is used for, comprise by inner bag, shell, be positioned at the housing that the vacuum multi-lay winding insulating jacket between inner bag and shell is formed, inlet, liquid outlet, return-air mouth are set on housing, on inlet, liquid outlet, return-air mouth, one way stop peturn valve are set respectively.During application, at the front end of pump or metering device housing is installed, the inlet of housing is connected with the cryogen pipeline, enters in the housing to receive the cryogen that flows into from storage tank, allows cryogen carry out gas-liquid separation in housing; The return-air mouth of housing is connected with cryogenic liquid storage tank by muffler, can make the gas cooled via return air pipe in the housing return storage tank; The liquid outlet of housing and pump or metering device can allow the cryogenic liquid that does not contain bubble enter pump or metering device by the liquid outlet outflow, can reach the purpose of this utility model thus.
In order to understand the state of the cryogenic liquid in the housing at any time, on housing, be provided with thermal resistance and temperature sensor, Pressure gauge and pressure sensor, safety valve.
The utility model is simple in structure, and is easy for installation, safe and reliable, can effectively the cryogen behind the pipeline of flowing through be carried out gas-liquid separation, infringement and the influence of avoiding pump and flowmeter to avoid cavitating.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.
Among the figure: 1, inner bag; 2, inlet; 3, vacuum multi-lay winding insulating jacket; 4, return-air mouth; 5 shells; 6, liquid outlet.
The specific embodiment
In the structure shown in the figure, a kind of cryogen gas-liquid separation device that is used for of the utility model, comprise by inner bag 1, shell 5, be positioned at the housing that the vacuum multi-lay winding insulating jacket 3 between inner bag and shell is formed, inlet 2, liquid outlet 6, return-air mouth 4 are set on housing, on inlet, liquid outlet, return-air mouth, one way stop peturn valve are set respectively.Cryogen is carried out gas-liquid separation in storage tank flows into housing, make liquid in the fluid be in the bottom of housing, and gas then returns storage tank through the return-air mouth 4 at its top, and the liquid that does not contain bubble is then flowed out by liquid outlet 6, enters pump or metering device.
Claims (2)
1, a kind of cryogen gas-liquid separation device that is used for, it is characterized in that: comprise by inner bag [1], shell [5], be positioned at the housing that the vacuum multi-lay winding insulating jacket [3] between inner bag and shell is formed, inlet [2], liquid outlet [6], return-air mouth [4] are set on housing, on inlet, liquid outlet, return-air mouth, one way stop peturn valve are set respectively.
