Description
Technical field
The utility model is related to a kind of water hammer absorber applied at fluid circuit switch position, particularly one kind and can added
The water hammer absorber of pressure type.
Background technology
, it is necessary to set many switches on fluid circuit, to be released or to be shunted.When opening switch, switch one
High-pressure fluid has been put aside in side, and switch opposite side does not have fluid under normal circumstances, is opening the moment of switch, high-pressure fluid is quick
Ground flows through to switch opposite side, and at the opposite side, usually air, under the impact compress of high-pressure fluid, due to air
Mobility it is relatively poor, air can not be quickly obtained scattered, and air can press tube wall because of compression, if tube wall aging,
Or intensity is not high, then it can be broken through by air, so as to fluid can be caused to leak.
Chinese utility model patent（The patent No.：201220330688.6）A kind of water hammer absorber is disclosed, belongs to machinery
Technical field.It solves the problem of use of existing water hammer absorber is more inconvenient.This water hammer absorber, including cylinder,
There is valve element and plug, valve element is located at cylinder outer end in cylinder, plug is located at cylinder the inner, and cylinder outer end, which is fixed with, to be connect
Have between valve element and plug in head, cylinder on compressed air, joint and be connected with triple valve, one of water outlet of triple valve
End is connected with joint.This water hammer absorber, which has, is easy to use and installs conveniently advantage.
This water hammer absorber after a long time use, due to the aging of sealing ring on valve element, abrasive action, valve element in addition
Air-tightness between cylinder inboard wall face can be deteriorated.In use, valve element is difficult to reply again after energy absorption is realized
In place, and valve element when absorbing energy, the speed that moves axially can be too fast, and have influence on the performance of water hammer absorber effect.Very
Can extremely occur the entirely ineffective situation of water hammer absorber, this can bring hidden danger to the security of pipeline.
The content of the invention
The utility model technical issues that need to address：A kind of adding pressure type water hammer absorber, this water hammer absorber are provided
Using effect be ensure that, good protective effect can be provided for pipeline.
To solve the technical problem, the technical solution of the utility model：A kind of adding pressure type water hammer absorber, including cylinder
And coupling head, coupling head is fixedly connected in the one end of cylinder, provided with piston in cylinder, is formed on coupling head internal face convex
Shoulder, piston is limited in cylinder, it is characterised in that be provided with valve, valve and inner barrel in the other end of cylinder
Communicate, movable sealing structure be used to limit the gas in cylinder from valve outside spill on the outside of cylinder.
Valve is connected on valve seat, and coupling tunnel is formed with the other end of cylinder, and valve seat is fixed on coupling tunnel.
Provided with the stopper rod extending into valve seat on valve seat, the interior side of stopper rod is used for the air inlet for being sealed in valve,
And form described sealing structure.
Stopper rod is threadedly coupled with valve seat, and handwheel is provided with the outer end of stopper rod.
Valve seat, which is provided with, is used for the air gauge of air pressure in measuring cylinder body.
Therefore, the beneficial effects of the utility model：, can be by cylinder after this water hammer absorber is connected on pipeline
It is provided for measuring the air gauge of inner barrel pressure, or periodically toward by way of pressurizeing in cylinder so that piston and cylinder
Air between body the other end keeps certain pressure, and piston results in good energy-absorbing function by compressed air,
So that this water hammer absorber can provide good protective effect for pipeline well.Due to can toward aerating in inflator,
So that forming a higher pressure in inflator, this enables this water hammer absorber to apply in high-pressure fluid transfer conduit,
So as to obtain the effect that common water hammer absorber can not be reached.
Brief description of the drawings
Fig. 1 is the longitudinal sectional view of this adding pressure type water hammer absorber.
Embodiment
With reference to accompanying drawing, this adding pressure type water hammer absorber is applied on the pipeline of trandfer fluid, is particularly applied on pipeline
At the position of switch, structure includes cylinder 5 and coupling head 1.Hollow coupling head 1 is socketed in the one end of cylinder 5, and leads to
Cross the mode of welding and realize both be connected and fixed.It is provided with cylinder 5 on piston 4, the internal face of coupling head 1 and forms convex shoulder
3, piston 4 is limited in cylinder 5, under normal conditions, piston 4 is located in coupling head 1.Set on the outer peripheral face of piston 4
There are twice O-ring seals 2, this axial location of twice O-ring seals 2 on piston 4 is separated.The other end of cylinder 5 is
Blind end, is provided with valve 10, valve 10 inside cylinder 5 with communicating, and movable sealing structure is used in the other end of cylinder 5
Limit the gas in cylinder 5 from valve 10 outside spill over the outside of cylinder 5.Described sealing structure can be stopper rod 8 described as follows,
It can also be the unidirectional steel ball structure of spring.In aerating, sealing structure releases the closure to oral area in valve 10, and aerating is finished
Afterwards, sealing structure can realize timely closure to oral area in valve 10, in case gas is excessive.
For ease of assembling valve 10, hollow coupling tunnel 6, coupling tunnel 6 and cylinder 5 are formed with the other end of cylinder 5
Inside is communicated, and valve 10 is connected on valve seat 11, and the grafting of valve seat 11 is fixed in coupling tunnel 6.
Because valve 10 is assemblied on valve seat 11, therefore it is easy on valve seat 11 provided with the stopper rod 8 extending into valve seat 11.
Axial restraint is socketed with sealing gasket on the interior side of stopper rod 8, by fitting for the sealing gasket and the gas outlet of valve 10, so as to
When not needing aerating, and realize sealing of the interior side of stopper rod 8 to valve 10.
For ease of operating sealing and the breakdown action of stopper rod 8, handwheel 7, stopper rod 8 and valve seat are provided with the outer end of stopper rod 8
11 threaded connections, and it is easy to the stable axial action on valve seat 11 of stopper rod 8.
Air gauge 9 is set on valve seat 11, air gauge 9 is communicated with the inside of valve seat 11, the inside of valve seat 11 is interior with cylinder 5
Portion is communicated, and air gauge 9 can be intuitively reacted the air pressure in cylinder 5, to determine the need for the aerating toward in cylinder 5,
Or in fueling process, whether the air pressure in cylinder 5 reaches setting value, consequently facilitating the barometric information in cylinder 5 is understood in time,
To entering the accurate aerating in ground inside cylinder 5.
