The realization of the present invention is described in detail below in conjunction with specific embodiment.
With reference to shown in Fig. 1-2, preferred embodiment is provided for the present invention.
Instrument protector, including anti-ripple device 100, one end of anti-ripple device 100 is formed with input port 111, the opposite other end
Delivery outlet 131 is formed with, after fluid is entered by input port 111, is flowed out from delivery outlet 131 and then enters instrument, in anti-ripple device 100
Portion has the first anti-ripple room 110, the second anti-ripple room 120 and three proofings ripple room 130, one end of the first anti-ripple room 110 and input
Mouth 111 connects, and the opposite other end is formed with the first anti-wave hole 112；One end of second anti-ripple room 120 and the first anti-wave hole
112 connections, the opposite other end are formed with the second anti-wave hole 121；One end of three proofings ripple room 130 and the second anti-wave hole 121
Connection, the opposite other end are connected with delivery outlet 131.
Wherein, fluid presss from both sides in the flow velocity direction of the first anti-ripple room 110 and the vector in the flow velocity direction of the second anti-ripple room 120
Angle is not less than 90 degree, and vector angle mentioned herein refers to the flow velocity of fluid as vector, and fluid is in the first anti-ripple room 110
In flow velocity direction compared to the flow velocity direction meeting in the second anti-ripple room 120 there are one 90 degree of angle is not less than, certainly, be equal to
90 degree or close also possible, also in the range of the including of this patent, particularly, in order to make anti-ripple device 100 whole linearly
Shape, the flow velocity direction that fluid enters input port 111 is consistent with the flow velocity direction for flowing out delivery outlet 131, i.e. fluid thataway
Into anti-ripple device 100, just still thataway comes out.
Instrument protector provided in this embodiment, provides anti-100 structure of ripple device, and anti-100 inside of ripple device just has first to prevent
Ripple room 110, the second anti-ripple room 120 and three proofings ripple room 130, three anti-ripple rooms are by the path of the fluid of entrance into line direction
Change, so as to be effectively reduced the impact that fluid may be brought, and whole process carries out inside anti-ripple device 100, anti-ripple
Device 100 is in vertical shape, in outside without occurring as the general bending of bend pipe, so instrument connect anti-ripple device 100 compared with
For bridge piece, less space can be saved.
In the present embodiment, in order to further reduce stair impact, fluid the flow velocity direction of the first anti-ripple room 110 with
Vector angle in the flow velocity direction of the second anti-ripple room 120 is 180 degree, and is also convenient for manufacturing in the structure of 180 degree, because only
Three anti-ripple rooms can be isolated with two blocks of plates with holes.
In order to facilitate the into and out of fluid, in the present embodiment, the first sealing cover 210 and the second sealing are further included
Lid 220, one end that the first sealing cover 210 has input port 111 to the formation of anti-ripple device 100 are connected and sealed, the second sealing cover
The formation of 220 pairs of anti-ripple devices 100 has one end of delivery outlet 131 into sealed connection, the first sealing cover 210 and the second sealing cover
220 are each formed with the hickey being connected with external pipe, are so better able to facilitate the connection and installation of instrument protector, stream
Body also more easily enters instrument protector.
In the present embodiment, the first sealing cover 210 and the second sealing cover 220 are divided equally with the end face that anti-ripple device 100 is connected
Sealing ring 300 is not provided with, and sealing ring 300 can be sealed interface with good, prevent leakage.
In the installation of actual instrument protector, since its diameter and length are smaller, so being tightened installation meeting
It is inconvenient, in the present embodiment, the end face that the formation of anti-ripple device 100 has input port 111 is provided with the first flange 140, and first
For flange 140 for being threadedly coupled with the first sealing cover 210, the end face that the formation of anti-ripple device 100 has delivery outlet 131 is provided with second
Flange 150, for the second flange 150 for being threadedly coupled with the second sealing cover 220, its integrated straight has been widened in the addition of two flanges
Footpath so that it is more prone to stress when tightening installation, and it also provides installation space for the screw thread installation of sealing cover.
For vertically-mounted instrument protector, in the present embodiment, the hickey of the first sealing cover 210 and
The hickey of second sealing cover 220 is located on same axis.
For Horizontal pressure table protector, sometimes for the needs of space layout, the input terminal of entire instrument protector with
And output terminal needs to carry out arranged off-centre, so, in other examples, the hickey of the first sealing cover 210 and the
The hickey of two sealing covers 220 is not located on same axis, and such setting has effectively adapted to different space layouts will
It asks.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.
