Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
As shown in fig. 1, the long-life metal bellows type energy accumulator comprises a casing 1 and a rear cover plate 2, wherein the casing 1 is a tubular structure with a hollow interior and a closed end and an open end, the rear cover plate 2 is fixedly welded at the open end of the casing 1, a gas charging port 3 is arranged at the closed end of the casing 1, the gas charging port 3 is welded after being filled with gas with fixed pressure, and a liquid inlet pipe 4 is arranged on the rear cover plate 2;
the outer wall that back shroud 2 is located 1 inside one side of casing is fixed with spacing pipe 5 to the inside extension of casing, and the outside cover of spacing pipe 5 is equipped with ripple liquid storage pipe 6, and 6 one end of ripple liquid storage pipe is fixed on back shroud 2 and the other end extends to casing 1 inside, and ripple liquid storage pipe 6 is fixed with sealed lid 7 to the one end that casing 1 inside extended.
Further, the space between the corrugated liquid storage pipe 6 and the closed end of the shell 1 is used as a gas storage cavity, when the gas storage device is used, gas is filled into the gas storage cavity from the gas inflation inlet 3, and the gas extrudes the corrugated liquid storage pipe 6 in the gas storage cavity to enable the corrugated liquid storage pipe to move to one side of the limiting pipe 5, so that energy storage is performed.
The inside of feed liquor pipe 4, spacing pipe 5 and ripple liquid storage pipe 6 communicates each other, and the pipeline liquid among the outside pipe-line system enters into the inside to ripple liquid storage pipe 6 through feed liquor pipe 4 and spacing pipe 5 when pressure change to promote ripple liquid storage pipe 6 to make a round trip to stretch out and draw back and carry out pressure compensation.
Be connected with telescopic tube 8 between sealed lid 7 and back shroud 2, telescopic tube 8 is used for carrying out the angle spacing to making a round trip to stretch out and draw back of corrugated liquid storage pipe 6.
The outside cover of feed liquor pipe 4 is equipped with flange 10, and feed liquor pipe 4 passes through flange 10 and outside pipe-line system intercommunication.
On the basis, when the device is used, energy conversion is completed through compressed gas, gas with preset pressure is filled into the gas storage cavity, the corrugated liquid storage pipe 6 is compressed to the position of the limiting pipe 5 by the pressure of the gas, the sealing cover 7 is pressed on the rubber cushion layer 9 in a pressing mode, and the corrugated liquid storage pipe 6 can be slowly stretched to balance the pressure along with the hydraulic pressure of an external pipeline system;
when the pressure of the external pipeline system exceeds the internal pressure of the gas storage cavity, oil liquid in the external pipeline enters the corrugated liquid storage pipe 6 from the liquid inlet pipe 4, gas in the gas storage cavity is compressed, and the pressure in the oil liquid is converted into gas internal energy;
when the pressure of the external pipeline system is lower than the internal pressure of the gas storage cavity, the oil in the corrugated liquid storage pipe 6 flows to the external system under the action of high-pressure gas to release energy
