Technical Field

The invention relates to the technical field of energy accumulators, in particular to a lining type piston energy accumulator with an alarm function.

Background

The accumulator is an indispensable auxiliary device in the hydraulic system, can play the roles of buffering and noise reduction, and can save a large amount of energy, so the accumulator is widely applied to the hydraulic system. According to the structural division of the energy accumulator, the conventional energy accumulator products mainly comprise a bag type energy accumulator and a piston type energy accumulator, wherein the bag type energy accumulator cannot bear frequent pressure fluctuation and larger load, otherwise, the bag type energy accumulator is easy to cause a leather bag rupture accident, and the piston type energy accumulator well makes up the defects of the bag type energy accumulator.

The common piston type energy accumulator in the market is single-layer carbon steel, alloy steel or stainless steel. And the bearing, corrosion resistance and cost cannot be effectively controlled. And the piston energy accumulator commonly used at present does not have an alarm device, can not effectively detect the working state of the energy accumulator, can not guarantee timely replacement and maintenance, and even can influence the system function.

In summary, the present invention provides a lined piston accumulator with an alarm function.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a lining type piston energy accumulator with an alarm function, which has the advantages of reasonable structural design, good pressure bearing effect, low cost and corrosion resistance, and can effectively detect the working state of the energy accumulator in time so as to ensure the timely replacement and maintenance and further ensure the system function.

In order to achieve the purpose, the invention is realized by the following technical scheme: the lining type piston energy accumulator with the alarm function comprises a protective cap, a heavy type inflation valve, a light spring washer, an inner hexagonal cylinder head screw, a high-pressure medium sensor, a gas end cover, a shell, a piston, a supporting ring, a two-way sealing device, a one-way sealing device, an O-shaped sealing ring, a check ring and an oil end cover, wherein a 316L stainless steel lining is arranged in the shell, the gas end cover and the oil end cover are arranged at two ends of the shell through the O-shaped sealing ring and the check ring, the high-pressure medium sensor and the heavy type inflation valve are arranged on the gas end cover, the protective cap is fixed on the gas end cover outside the heavy type inflation valve through the light spring washer and the inner hexagonal cylinder head screw, and the piston is arranged inside the shell through the supporting ring.

preferably, the high-pressure medium sensor is an alarm medium sensor.

The invention has the following beneficial effects:

1. The shell of the invention adopts a 316L stainless steel lining, which can bear high pressure, ensure corrosion resistance and greatly save industrial cost.

2. The high-pressure medium sensor is a medium sensor for alarming, and can effectively detect the working state of the energy accumulator in time so as to ensure the replacement and maintenance in time and further ensure the function of the whole system.
