The specific embodiment
Below in conjunction with each embodiment and accompanying drawing thereof the utility model liquid interlayer container is described in further detail.
In embodiment illustrated in fig. 11, the liquid interlayer container comprises stainless steel inner container 1, carbon steel outer layer container 2, liquid dielectric 3 three parts; Stainless steel inner container 1 and carbon steel outer layer container 2 relative fixed; Full of liquid medium 3 in the closed interlayer that is constituted between inner bag 1 and the outer layer container 2.When the flowing material of packing in the stainless steel inner container 1 (gas or liquid) and when having certain pressure, because liquid can be thought the material that cannot compress under tens MPas (a hundreds of barometric pressure) condition, so, if there is pressure to exist in the inner bag 1 of described liquid interlayer container, this pressure can directly be passed to carbon steel outer layer container 2 by liquid dielectric 3, and the stainless steel inner container 1 interior suffered pressure and the equilibrium of pressure of liquid dielectric 3, thereby thin stainless steel inner container 1 can not destroyed.
In embodiment illustrated in fig. 22, on the stainless steel inner container 1 of liquid interlayer container pressurizer 4 is installed also, this pressurizer is a piston cylinder operator, is made of piston sleeve 6 and piston 5, and piston 5 can slide along piston sleeve 6.When the pressure that bears in the stainless steel inner container 1 different with the pressure of liquid dielectric 3 and when having difference of pressure, under this action of pressure, small slip will take place in piston 5 in sleeve 6, thereby the volume to inner bag 1 and interlayer carries out small adjustment, so that the external and internal pressure of stainless steel inner container 1 reaches balance, prevent that inner bag is destroyed under big action of pressure.
In embodiment illustrated in fig. 33, what installed on the stainless steel inner container 1 of liquid interlayer container is can be along the bellows-type pressurizer 4 of its axial stretching, bellows open end and inner bag fix, and its inner chamber is communicated with the other end closure of openings of bellows with interlayer.When inside and outside stainless steel inner container 1, having difference of pressure, the length of bellows changes along its length, to make the external and internal pressure of stainless steel inner container 1 reach balance, avoid stainless steel inner container 1 destroyed under big action of pressure by adjusting inner bag 1 interior volume with interlayer.
In embodiment illustrated in fig. 44, what install on the stainless steel inner container 1 of liquid interlayer container is diaphragm type pressurizer 4, and the diaphragm of being made by rubber or suitable material is fixed on the inner bag 1 with bonding way, is processed with through hole with the diaphragm corresponding section on the inner bag.The shape of this diaphragm type pressurizer 4 can change within the specific limits along its thickness direction.When the pressure in the stainless steel inner container 1 during greater than the pressure of liquid dielectric 3, diaphragm is pressed towards interlayer one side, and liquid dielectric 3 pressure raise, and reaches balance until the external and internal pressure of stainless steel inner container 1; If the pressure in the stainless steel inner container 1 is during less than the pressure of liquid dielectric 3, diaphragm is pressed towards opposite side, and the pressure of liquid dielectric 3 reduces, and finally makes the external and internal pressure of stainless steel inner container 1 reach balance.
