Description

A kind of bladder type hydropneumatic accumulator of the anti-broken bolt of band
Technical field
The utility model is related to hydraulic accumulator technical fields, and in particular to a kind of bladder type hydropneumatic accumulator of the anti-broken bolt of band.
Background technology
Accumulator is a kind of energy savings device in hydraulic system, it is in due course is by the energy conversion in system Compression energy or potential energy store, and when system needs, and compression energy or potential energy are changed into the energy such as hydraulic pressure or air pressure and discharged Out, feed system is mended again.When system instantaneous pressure increases, it can absorb the energy of this part, to ensure entire system Unite pressure it is normal, and hydraulic system be one kind using fluid as working media, using fluid pressure energy and pass through control valve Equal attachmentes manipulate the device of hydraulic actuating mechanism work.And accumulator be broadly divided into operation when, hydraulic system pass through change pressure It is strong to increase or reduce active force, so that control mechanism is run.And in the quick variation of hydraulic load, easy to produce hydraulic pressure arteries and veins It is dynamic, it forms impact phenomenon and thus generates noise and vibrations;Simultaneously, hydraulic system is frequently necessary to carry rapidly in a short time High or reduction pressure, to adapt to the variation of extraneous load.Therefore, bladder type hydropneumatic accumulator becomes essential important in hydraulic system Component.Bladder type hydropneumatic accumulator can store the excess energy of hydraulic system, and be released again in hydraulic work system, both Pulsation can be reduced, reduce noise, and mass energy can be saved.Therefore various types of bladder type hydropneumatic accumulators also come into being.
In the prior art, various bladder type hydropneumatic accumulator technologies are increasingly ripe, but to the guarantor of bladder type hydropneumatic accumulator air bag But research is few for shield.And the gas that escapes naturally, it safeguards not in time, insufficient in the intracapsular air pressure of accumulator, air bag is damaged, causes Accumulator fails.When the insufficient pressure of air bag, balloon contraction makes air bag be compressed at the top of air bag, gets into Valve for aerocyst opening, holds Easily make air bag stress damaged, reduce the service life of air bag, increases operation cost.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of bladder type hydropneumatic accumulator of the anti-broken bolt of band, To solve above-mentioned deficiency.The device enables to the air bag of accumulator to prolong the service life, not cracky, improves the safety of device Property, to reduce use cost.
The purpose of this utility model is achieved through the following technical solutions:
A kind of bladder type hydropneumatic accumulator of the anti-broken bolt of band, including:Valve protective cover, charge valve, valve duct, retainer nut, shell, Capsule, spool, spring, rubber filler ring, support ring, valve block, screw plug, the bladder type hydropneumatic accumulator further include by valve duct with The anti-broken bolt of charge valve connection;The valve protective cover is arranged in the outside of charge valve;It is arranged between the shell and valve protective cover There is retainer nut;The front end of the anti-broken bolt is placed in capsule;The capsule is placed in shell;The housing chamber lower part is equipped with Spool, rubber filler ring, support ring;The lower edge of the spool is provided with spring;The lower part of the housing is provided with valve block;The valve Screw plug is additionally provided in housing.
Before using the bladder type hydropneumatic accumulator, it should simply be understood entire bellows air bag dispenser, pass through inflation first Gas is put by valve, then enters anti-broken bolt by valve duct, and using the stomata of anti-broken bolt, gas enters in capsule, makes Its air pressure increases, and balloon inflation expands, and squeezes spool, and the hydraulic oil in housing chamber is squeezed out;Conversely, then by hydraulic oil Into in housing chamber so that the air pressure of air bag reduces.When air bag pressure it is small to a certain extent after, anti-broken bolt will be pushed up, to So that air bag will not be compressed to inflation valve port, prevent from breaking valve nozzle, to which protection is not damaged to air bag, extends and use the longevity Life.
In said program, for optimization, further, the anti-broken bolt is the anti-broken bolt that can be slided.
Further, the anti-broken bolt front end is equipped at least a stomata.
Further, the length for being shorter in length than anti-broken bolt in the valve duct.
Further, the capsule be filled with nitrogen.
Further, the spool is mushroom valve.
The utility model has the beneficial effects that:The utility model enables to the air bag of accumulator, and cracky, extension do not make With the service life, is greatly improved to the service life of bladder type hydropneumatic accumulator, the safety of device is improved, in air pressure deficiency, as long as right Accumulator is inflated, accumulator energy normal use, to reduce use cost.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model;
In figure, 1- valve protective covers, 2- charge valves, 3- retainer nut, 4- capsules, 5- shells, 6- spools, 7- springs, 8- valves Housing, 9- rubber filler rings, 10- support rings, the anti-broken bolts of 11-, 12- screw plugs, 13- valves duct.
Specific implementation mode
The technical solution of the utility model, but the scope of protection of the utility model are described in further detail below in conjunction with the accompanying drawings It is not limited to as described below.
As shown in Figure 1,
