Abstract
The utility model discloses a compressor restrictor ring, which comprises a restrictor ring body, wherein the center of the restrictor ring body is a circular through groove, the wall surface of the through groove is provided with a plurality of grooves, and the cross section of each groove is triangular; when high-pressure gas passes through the throttling ring, the air flow makes the turning-back movement in different directions on the surface of the groove, the movement curve is similar to a wedge shape, the air flow continuously turns back in the groove to enable the movement speed of the air flow to be gradually reduced, the high-pressure air flow gradually tends to the medium-pressure air flow after the speed is reduced, and the large pressure reduction effect of the throttling ring body is achieved.
Description
Technical field
This utility model relates to a kind of compressor accessory, particularly to a kind of compressor restrictor ring.
Background technology
The effect of the restrictor ring in compressor is the gases at high pressure reducing pressure by regulating flow that will pass through, in becoming, the gas of low pressure, thus when gas is by follow-up sealing ring, reducing the impact to sealing ring, it is ensured that sealing effectiveness.
At present, the disclosed restrictor ring on market, inner wall smooth, gas by time the Pressure Drop that produces less, cause that follow-up sealing pressure is big.
Utility model content
The purpose of this utility model is to provide the compressor restrictor ring that a kind of Pressure Drop is bigger.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of compressor restrictor ring, including restrictor ring body, described restrictor ring body central is circular groove, and the wall of described groove is provided with some grooves, and the cross section of described groove is triangle.
Pass through technique scheme, when gases at high pressure are by restrictor ring, the fold return motion of different directions is there is in air-flow on the surface of groove, this curve movement wedge like, so air-flow continuous fold return motion in this groove makes its movement velocity be gradually lowered, and high pressure draught just trends towards middle pressure gas stream gradually by after reduction of speed, namely achieve the pressure drop effect that restrictor ring body is bigger.
This utility model is further arranged to: described channel section is equilateral triangle.
By technique scheme, the stability of equilateral triangle is higher, therefore groove shape and structure be hardly damaged.
This utility model is further arranged to: described groove is placed equidistant on groove.
Pass through technique scheme, it is ensured that when air-flow is by restrictor ring body, be constantly in the state of deceleration blood pressure lowering, it is provided that continual deceleration antihypertensive effect, it is achieved higher pressure drop effect.
This utility model is further arranged to: adjacent described groove composition latch, the cross section of described latch is isosceles trapezoid.
Pass through technique scheme, it is ensured that during gases at high pressure circulation, card tooth surface is not easy abrasion.
This utility model is further arranged to: spacing is card topland width 2.5 times of adjacent described latch.
By technique scheme, circulation place that end face is gas of latch, the groove between card tooth is air-flow blood pressure lowering place, by this pro rate, it is ensured that the circulation of gas and blood pressure lowering are in the state of stable adjustment.
This utility model is further arranged to: described restrictor ring body outer rim rounding.
By technique scheme, the outer surface transition of restrictor ring body is smooth, it is to avoid restrictor ring body cuts hands in use.
This utility model is further arranged to: described restrictor ring body is made up of PEEK.
By technique scheme, the mechanical performance of PEEK material is excellent, resistance to chemical attack, high temperature resistant, fire-retardant, it is adaptable to restrictor ring body.
In sum, this utility model has the advantages that the pressure drop effect that improve restrictor ring body, and structure is more stable.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Embodiment one: a kind of compressor restrictor ring, including restrictor ring body 1, described restrictor ring body 1 center is circular groove 2, and the wall of described groove 2 is provided with some grooves 3, and the cross section of described groove 3 is triangle; When gases at high pressure are by restrictor ring, the fold return motion of different directions is there is in air-flow on the surface of groove 3, this curve movement wedge like, so air-flow continuous fold return motion in this groove 3 makes its movement velocity be gradually lowered, and high pressure draught just trends towards middle pressure gas stream gradually by after reduction of speed, namely achieve the pressure drop effect that restrictor ring body 1 is bigger.
Preferably, described groove 3 cross section is equilateral triangle; The stability of equilateral triangle is higher, therefore groove 3 shape and structure be hardly damaged.
Groove 3 is placed equidistant on groove 2; The state of deceleration blood pressure lowering it is constantly in, it is provided that continual deceleration antihypertensive effect, it is achieved higher pressure drop effect when ensureing air-flow by restrictor ring body 1.
Preferably, adjacent described groove 3 forms latch 4, and the cross section of described latch 4 is isosceles trapezoid; When ensureing gases at high pressure circulation, latch 4 surface is not easy abrasion.
Embodiment two: with the difference implementing be, 2.5 times that spacing is latch 4 end face width of adjacent described latch 4; Circulation place that end face is gas of latch 4, the groove 3 between latch 4 is air-flow blood pressure lowering place, by this pro rate, it is ensured that the circulation of gas and blood pressure lowering are in the state of stable adjustment; Preferably, described restrictor ring body 1 outer rim rounding; The outer surface transition of restrictor ring body 1 is smooth, it is to avoid restrictor ring body 1 cuts hands in use.
Preferably, described restrictor ring body 1 is made up of PEEK; The mechanical performance of PEEK material is excellent, resistance to chemical attack, high temperature resistant, fire-retardant, it is adaptable to restrictor ring body 1.
In sum, this utility model has the advantages that the pressure drop effect that improve restrictor ring body 1, and structure is more stable.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made the amendment not having creative contribution as required by those skilled in the art after reading this specification, but as long as being affected by the protection of Patent Law in right of the present utility model.
