Pressure release space 5；The installing pipe 4 side relative with water supply connector 2 is provided with the movable span 6 to be connected with pressure release space 5；It is described
The motion bar 7 to match with it is installed in movable span 6；The inwall of movable span 6 is provided with a stopper slot 8, the middle part of motion bar 7
It is externally provided with the spacing ring 9 to match with stopper slot 8；A limit spring 10 is arranged with outside the motion bar 7, limit spring 10 is located at
In stopper slot 8；Described one end of limit spring 10 is contacted on spacing ring 9, and the other end is contacted on the inwall of stopper slot 8；The work
7 anterior termination of lever is relative with pressure release space 5, and 7 anterior termination of motion bar is provided with inlet opening 11；The 7 anterior outer wall of motion bar
Provided with some water holes 12 being circularly and evenly distributed；The spacing ring 9 is provided with some limbers being circularly and evenly distributed
13；The rear portion termination of motion bar 7 is provided with an extruded hole 14；The rear portion outer wall of motion bar 7 is provided with some circumferentially uniform points
Cloth send water hole 15；The outer wall of installing pipe 4 be provided with some equally distributed cushion holes 16, open and close hole 17, cushion hole 16 with
Hole 17 is opened and closed to be interspersed；Covered with an elastic membrane 18 at the cushion hole 16；The keying aperture side of hole 17 is hinged with one
Plate 19 is opened and closed, opens and closes and forms estuary between plate 19 and keying hole 17；Keying plate 19 back is provided with an arc elastic post 20,
Arc elastic post 20 is located in pressure release space 5；The installing pipe 4 side relative with water out adapter 3 is provided with one and the phase of installing pipe 4
The rectifying tube 21 of matching, rectifying tube 21 is in front wide and rear narrow round table-like.
The sebific duct 1 is wrapped with a thermal insulation layer 22, and thermal insulation layer 22 is flexible material.
Application method of the present utility model is as follows：First pass through water supply connector 2, hose assembly is attached to liquid by water out adapter 3
In pressure system, when the fluid pressure in hydraulic system is excessive, highly pressurised liquid will enter to installing pipe 4 by water supply connector 2
Pipeline in, and enter the pipeline of installing pipe 4 in when, highly pressurised liquid can impact to motion bar, make motion bar 7 towards pressure release
The direction of space 5 is moved, and now limit spring 10 is compressed, and motion bar 7 is moved by spacing ring 9 along the track of stopper slot 8
Dynamic, the front portion of motion bar 7 is progressed into stopper slot 8, and 7 anterior outer wall of motion bar is no longer covered by the inwall of movable span 6, originally
The highly pressurised liquid being full of in extruded hole 14 can then flow to by sending water hole 15 to flow out, and by the limbers 13 on spacing ring 9
Motion bar 7 is anterior.
With continually entering for highly pressurised liquid, highly pressurised liquid can be full of whole stopper slot 8, the highly pressurised liquid in stopper slot 8
Can then be flowed into inlet opening 11 by water hole 12, finally flowed into pressure release space 5, with pressure release space 5 highly pressurised liquid not
Disconnected savings, highly pressurised liquid can be full of whole pressure release space 5, and now the highly pressurised liquid in pressure release space 5 can then enter to opening and closing plate 19
Go and extrude, open and close plate 19 under the effect of the pressure with opening and closing the phase of hole 17 closure, be open and close in keying hole 17 after the masking of plate 19, high pressure
Liquid can not flow out pressure release space, can only constantly put aside in pressure release space 5, fluid pressure can then squeeze to elastic membrane 18
Pressure, when elastic membrane 18 is extruded, elastic membrane 18 then can enter row buffering to highly pressurised liquid by its own resilient, and with elastic membrane 18
Constantly it is extruded, elastic membrane 18 can be protruding in the pipeline of installing pipe 4, and the elastic membrane 18 after protrusion then can be to flowing into installing pipe 4
Highly pressurised liquid cause to hinder, so as to reduce the flow velocity of highly pressurised liquid, play the effect of compensator or trimmer pressure, and the elastic membrane 18 protruded
Not only there is the elastic performance of itself, be full of the buffering effect that its internal liquid flowing makes it have water pocket, make highly pressurised liquid
One of buffering itself is similarly formed, resource is utilized effectively, after row buffering is entered by the elastic membrane 18 of multiple protrusions,
Hydraulic pressure can then obtain gently.
However, to ensure that the liquid after hydraulic pressure recovers normal keeps normal flow, be not in the situation of interim card,
Rectifying tube 21 can carry out rectification to the liquid that is flowed out out of installing pipe, and rectifying tube 21 is in front wide and rear narrow round table-like, in liquid
In the case that body flow is constant, as the bore of rectifying tube 21 constantly becomes big, flowing through the fluid pressure of rectifying tube 21 can obtain again
Secondary buffering, make finally to be maintained at normal pressure from the liquid of water out adapter outflow, so that hydraulic system uses.
Understand in summary, the utility model can be inputted highly pressurised liquid to pressure release space by the extruding to motion bar 7
In 5, so as to play the effect of pressure release, when that can not carry out pressure release completely, fluid pressure can will then open and close plate 19 and close, now bullet
Property film 18 by elastic performance carry out second of pressure buffer, by highly pressurised liquid extruding cause to be protruding in the pipeline of installing pipe 4
Elastic membrane can then be buffered again to flowing through the liquid in installing pipe 4 again, highly pressurised liquid is farthest delayed
Punching, highly pressurised liquid can not be formed to sebific duct and oppress, be not in the situation of rupture, ensure the personal safety of staff, prolong
The service life of long length hose 1, and the highly pressurised liquid after being buffered can then keep normal flow, hydraulic system will not be caused to add
Heat, ensure operational efficiency.
In the case of fluid pressure is normal, motion bar can then reset in the presence of limit spring 10, and open and close plate 19
Then reset and open in the presence of elastic 0, pressure release space 5 is connected by opening and closing hole 17 with the pipeline of installing pipe 4, is full of originally
Pressure release space 5 can be then flowed out in the liquid in pressure release space 5, and the sebific duct 1 that flows down out is driven in the liquid for flowing through installing pipe 4, from
And the space vacateed in pressure release space 5 is for next pressure release.
Sebific duct 1 is wrapped with thermal insulation layer 22, and thermal insulation layer 22 is flexible material, and thermal insulation layer 22 has effect of heat insulation, can made
Hose assembly is in when hot environment is used and is also unaffected, and ensures stability when hose assembly uses.
