Description
Technical Field
The invention relates to an energy accumulator, in particular to an extension rod displacement type piston energy accumulator.
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.
Piston rods of piston energy accumulators on the market at present are not in an extending structure, so that a customer cannot conveniently and accurately control the liquid discharge amount of the energy accumulator, and the use effect is poor.
In summary, the present invention provides an extension rod displacement piston accumulator.
disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide an extension rod displacement type piston energy accumulator which is reasonable in structural design, can flexibly set a position switch through an extended piston rod, can further accurately control the liquid discharge amount of the energy accumulator, and is convenient and reliable to use.
In order to achieve the purpose, the invention is realized by the following technical scheme: extension bar displacement formula piston energy storage ware, which comprises a housin, gu fixed ring, first oil end cover, O type sealing washer, the retaining ring, a piston, two-way sealing device, one-way sealing device, the supporting ring, the guide bar, second oil end cover and direction sealing piece, casing both ends inner wall passes through O type sealing washer, the retaining ring is provided with first oil end cover and second oil end cover respectively, first oil end cover and second oil end cover outside are through solid fixed ring and casing cooperation, the casing is inside through two-way sealing device, one-way sealing device, the supporting ring is provided with the piston, the piston cooperatees with the guide bar, the guide bar passes second oil end cover and stretches out the casing setting, second oil end cover is provided with the direction sealing piece with guide bar outside cooperation department.
Preferably, the guide rod is further provided with a position control switch, so that the liquid discharge amount of the energy accumulator can be accurately controlled.
The invention has the beneficial effects that: structural design is reasonable, can set up position switch in a flexible way through the piston rod that stretches out, and then can the accurate control energy storage ware the displacement, convenient to use is reliable.
Drawings
the invention is described in detail below with reference to the drawings and the detailed description;
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is an enlarged view of part A of the present invention;
Fig. 3 is a left side view of the present invention.
Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.
Referring to fig. 1 to 3, the following technical solutions are adopted in the present embodiment: extension rod displacement type piston energy accumulator, including casing 1, solid fixed ring 2, first oil end cover 3, O type sealing washer 4, retaining ring 5, piston 6, two-way sealing device 7, one-way sealing device 8, supporting ring 9, guide bar 10, second oil end cover 11 and guide seal block 12, casing 1 both ends inner wall passes through O type sealing washer 4, retaining ring 5 is provided with first oil end cover 3 and second oil end cover 11 respectively, first oil end cover 3 and the cooperation of second oil end cover 11 outside through solid fixed ring 2 with casing 1, casing 1 is inside through two-way sealing device 7, one-way sealing device 8, supporting ring 9 is provided with piston 6, piston 6 and guide bar 10 cooperate, guide bar 10 passes second oil end cover 11 and stretches out casing 1 setting, second oil end cover 11 and guide bar 10 outside cooperation department are provided with guide seal block 12.
It should be noted that the guide rod 10 is further provided with a position control switch, so that the liquid discharge amount of the accumulator can be accurately controlled.
The invention can set the position switch at the position with specific size according to the requirement by extending the guide rod (piston rod) out of the shell of the energy accumulator, can accurately control the liquid discharge quantity of the energy accumulator, greatly improves the energy storage effect of the energy accumulator, is more convenient and reliable to use,
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
