Description

A kind of piston accumulator
Technical field
The utility model relates to a kind of piston accumulators, belong to hydraulic pressure auxiliary element technical field.
Background technique
Accumulator is indispensable auxiliary device in hydraulic system, can not only play buffering and Noise Reduction, but also can be with The a large amount of energy is saved, thus is widely used in hydraulic system.It is divided according to accumulator structure, accumulator common at present produces Product mainly have bellows and two kinds of piston type, and wherein bladder type hydropneumatic accumulator cannot bear frequent pressure oscillation and biggish load, no Leather bag break accident is then easily caused, piston accumulator then compensates for the defect of bladder type hydropneumatic accumulator well.
And existing piston accumulator, there are some defects, the end cap of piston accumulator is an integral structure, in this way Structure to will cause end cap volume big, be not easy to dismantle, while a kind of sealing element being used only inside existing accumulator and seals, reach Less than better seal effect.
Utility model content
In view of the above-mentioned problems, the technical problem to be solved by the present invention is to provide a kind of piston accumulators.
The piston accumulator of the utility model, it includes protective cap, heavy charge valve, single coil spring lock washer light type, interior hexagonal Fillister head screw, gas end end cap, locknut, shell, piston, support ring, two way seal, one-way sealing, O-ring seal, retaining ring and Oily end end cap, the housing forward end are provided with gas end end cap, and housing rear end is provided with oily end end cap, and gas end end cap and oily end End cap passes through locknut and connect with shell, and the housing central section is provided with piston, and piston is located at gas end end cap and oily end end It covers in closed cavity, the gas end end cap front center is provided with heavy charge valve, and is provided with guarantor on heavy charge valve Helmet, the protective cap is fixed by hexagon socket cap head screw and gas end end cap, and hexagon socket cap head screw and protection Cap junction is provided with single coil spring lock washer light type, the gas end end cap and oily end end cap and housing junction is provided with O-shaped sealing Circle and retaining ring, the piston and housing junction are provided with support ring, two way seal and one-way sealing.
Preferably, being all made of split type structure design between the gas end end cap and oily end end cap and locknut.
Preferably, the retaining ring is SB1 type, and retaining ring is made of polytetrafluoroethylene (PTFE) material.
The utility model has the beneficial effects that its structure is simple, rationally, gas end end cap and oily end end cap pass through lock for design Mother connect with shell, and split type structure design is all made of between gas end end cap and oily end end cap and locknut, so that front and rear cover Easily assembly, to reduce labor intensity, improves assembling quality, while setting between end cap and shell, between piston and shell There is multi-layer sealing structure, sealing effect is good, avoids oil leak, gas leak phenomenon.
