Abstract
The utility model discloses a sac type hydraulic buffer, which can adjust and eliminate pressure pulsations of liquids. The utility model is formed by that the opening end of a casing 2 is connected with a valve 5 with a dual channel 4 by a screw nut 3, wherein, an air sac 1 is arranged in the casing 2, one end of a casing 2 is provided with an opening, and the other end is provided with an opening for closing. The position, corresponding to the valve body 5, is provided with an inlet and an outlet joints 6 and 7 which are communicated with the dual channel 4. The utility model can reliably eliminate the high-frequency pressure pulsations of the liquids, and reduce the noises and vibrations of systems. The utility model has the advantages that structure is simple, installation and maintenance are convenient, sensitivity is high, the effect of buffering is good, the service life of an instrument is prolonged, etc.
Description
The utility model relates to a kind of hydraulic pressure auxiliary device, particularly relates to a kind of can regulate or eliminates the hydraulic pressure auxiliary device that fluid pressure is pulsed.
Industries such as at present domestic oil, chemical industry, metallurgy adopt bladder type hydropneumatic accumulator to eliminate the fluid pressure pulsation mostly.This accumulator is that the housing that closes up, the capsule in the housing and a valve body that is connected with housing constitute by two ends mainly.Be filled with gas in the capsule, can pass through the contraction and expansion storage pressure of capsule, and alleviate pulsation.But because accumulator only is provided with a passage, for this reason, when the liquid pulsation frequency was higher, air bag did not also have enough time to react liquid is directly passed through from connecting tube, and can't eliminate this high-frequency pressure pulsation.The pulsation of this high-frequency pressure is common in above-mentioned field, and it not only influences the working life of some accurate executive components and measuring cell in the system, causes adverse consequences but also will produce noise and vibration etc.
The purpose of this utility model is that a kind of high-frequency pressure pulsation both can eliminated will be provided, again can the raising system in working life of accurate executive component and measuring cell, and can reduce the capsule formula hydraulic bjuffer of noise and vibration.
The purpose of this utility model is achieved in that this model utility comprises the air bag in housing, the housing, the set poppet valve of valve body that is connected with housing and valve body central authorities, at one end constitutes through the valve body that nut is connected and fixed an inlet/outlet joint that is provided with Twin channel and is connected with Twin channel for uncovered its open-mouth end of housing.
The utility model makes this model utility reliably eliminate this pressure pulsation when the liquid pulsation frequency is higher owing to having taked Twin channel and air bag, poppet valve structure combining, reduces system noise and vibration.And have simple in structure, convenient for installation and maintenance, highly sensitive, a good buffer effect, the advantages such as working life that can prolong the relevant instrument and equipment of system.
In conjunction with the accompanying drawings the utility model is described in further details:
Fig. 1 is the overall structure schematic representation of capsule formula hydraulic bjuffer.
Capsule formula hydraulic bjuffer shown in Figure 1 is that to establish air bag 1, an end in one be that the open-mouth end of uncovered housing 2 connects a valve body 5 that is provided with Twin channel 4 by nut 3 and constitutes.Be provided with the inlet/ outlet joint 6,7 that is connected with Twin channel 4 in valve body 5 corresponding parts.Import and export joint 6,7 and is connected with valve body 5 flanges, at the poppet valve 9 that the central authorities of valve body 5 have a spring 8 to support, poppet valve 9 end and valve body bolt also are provided with an end cap 10 on the valve body 5 of poppet-valve 9 ends.In valve body 5 and housing 2, import and export joint 6,7 and end cap 10 each joint seal ring is set all.Import and export joint 6,7 docked and charged in air bag 1 by gas charging valve 11 certain pressure with system pipeline gas during use, but the passage that the utility model force fluid enters the Twin channel 4 that communicates with inlet union 6 valve body 5 from import connecting head 6 is to buffer, and another passage inlet/outlet joint 7 through Twin channel 4 flows out again.Liquid can directly stimulate air bag 1 like this, and when 1 contraction of fluid pressure rising air bag, pressure reduces air bag 1 and expands, and regulates and eliminate the high-frequency pressure pulsation with this, and pressure balanced liquid is exported from outlet connection 7.Cross low or liquid disappears when fluid pressure, poppet valve 9 cuts out Twin channel 4 automatically under the pressure effect of air bag 1, and when fluid pressure recovers just often, poppet valve 9 is just under the effect of fluid pressure and spring 8 and open automatically.This model utility is recovered proper functioning.This model utility is applicable to multiple liquid medium, can be widely used in fields such as oil, chemical industry, metallurgy, mine, engineering machinery.
